    A strong Supply Chain Manager does not simply find a supplier with a good price and ask for samples. The process is closer to commercial sourcing + forensic due diligence + quality engineering + compliance.

    The OECD’s current guidance frames this as risk-based due diligence: identify risks, prioritize them, prevent/mitigate them, track results, communicate, and remediate where necessary. It also emphasizes that companies should not assume a certificate or third-party audit alone proves responsible conduct.

    1. Start by defining the supplier you actually need

    Before searching Asia, build a supplier specification:

    • Product and technical specifications
    • Annual/monthly volume
    • Target landed cost
    • Required MOQ
    • Quality tolerances
    • Required certifications
    • Packaging requirements
    • Lead-time target
    • Payment terms
    • Incoterm preference
    • Destination markets
    • Required production capacity
    • IP/confidentiality requirements
    • Regulatory requirements for the destination country

    This prevents a common mistake: selecting the "cheapest factory" before determining whether it can actually meet the commercial and technical requirements.


    2. Build a longlist of 20–50 potential suppliers

    A manager will normally use several channels, rather than relying on one marketplace.

    Common sourcing channels

    B2B marketplaces

    • Alibaba
    • Global Sources
    • Made-in-China
    • IndiaMART
    • TradeIndia

    Trade shows

    • Canton Fair
    • Hong Kong trade shows
    • Vietnam Expo
    • regional industry-specific exhibitions

    Industry associations

    • Manufacturing associations
    • Chambers of commerce
    • Export associations

    Sourcing agents

    • Particularly useful when entering an unfamiliar country or product category.

    Referrals

    • Existing suppliers
    • Customers
    • freight forwarders
    • industry contacts
    • engineering consultants

    Direct factory research

    • Search manufacturers by product + country/region and approach them directly.

    The objective at this stage is not to pick a supplier. It is to create a sufficiently broad candidate pool.


    3. Separate "trader" from "manufacturer"

    This is one of the most important steps in Asian sourcing.

    A company may present itself as a manufacturer when it is actually:

    Your company → Trading company → Factory → Subcontractor

    That can create problems with price, quality, traceability and intellectual property.

    Ask:

    1. What is your legal company name?
    2. What is the registered factory address?
    3. Which products do you manufacture in-house?
    4. What processes are subcontracted?
    5. How many production lines do you have?
    6. How many employees?
    7. What is your monthly capacity?
    8. Who owns the facility?
    9. How long have you operated at that location?
    10. Can we conduct a factory audit?

    Then compare the answers against the physical factory.

    For example, if a company claims it manufactures 100,000 precision-machined components/month but has 25 employees and six machines, the numbers don't add up.


    4. Verify the legal entity

    Obtain and independently verify:

    • Business registration
    • Registered company name
    • Registration number
    • Factory address
    • Legal representative/ownership
    • Export license where applicable
    • Tax/VAT information
    • Bank-account ownership
    • Relevant industry licenses
    • Certifications
    • Litigation/insolvency information where available

    Don't simply accept PDFs supplied by the salesperson.

    For example, the Indian Embassy in Beijing explicitly advises companies dealing with Chinese suppliers to exercise due diligence and notes that preliminary credential checks can be supplemented with business licenses, financial documentation, industry qualifications and professional verification.

    Critical test: the company name on your contract, the company receiving your money, the company holding the relevant licenses, and the company operating the factory should make sense together.


    5. Check financial health

    A supplier can produce excellent samples and still be a terrible supplier if it is financially unstable.

    Look for:

    • Years in business
    • Revenue trend
    • Major customers
    • Employee count
    • Production investment
    • Debt/financial distress indicators
    • Payment behavior
    • Ownership changes
    • Dependence on one customer
    • Dependence on one raw-material supplier

    For an important supplier, consider a professional credit report.

    Red flags

    Be particularly careful if:

    • They demand 100% payment upfront.
    • Their bank account belongs to a different company.
    • They suddenly change bank accounts.
    • They refuse reasonable financial questions.
    • Their claimed capacity is inconsistent with the factory.
    • Their price is dramatically below every competitor.
    • They have recently changed legal entities.
    • They cannot explain ownership clearly.

    6. Audit the factory — preferably before committing significant money

    This is where sourcing becomes serious.

    A factory audit should examine at least:

    Production

    • Machinery
    • Production lines
    • Capacity
    • Production flow
    • Maintenance
    • Automation
    • Bottlenecks
    • Subcontracting
    • Production planning

    Quality

    • Incoming inspection
    • In-process inspection
    • Final inspection
    • Testing equipment
    • Calibration
    • Non-conformance procedures
    • Corrective actions
    • Traceability
    • Batch records

    Warehouse

    • Raw-material storage
    • Finished goods
    • FIFO/FEFO where applicable
    • Inventory controls
    • Lot identification
    • Environmental controls

    People

    • Number of workers
    • Skilled vs. unskilled workforce
    • Training
    • Turnover
    • Shift structure
    • Management experience

    EHS/social compliance

    • Worker safety
    • PPE
    • Emergency exits
    • Fire systems
    • Working hours
    • Wage practices
    • Worker accommodation where relevant
    • Environmental controls

    And don't let a beautiful showroom substitute for looking at the actual production floor.


    7. Don't treat certifications as proof by themselves

    A supplier might show:

    • ISO 9001
    • ISO 14001
    • ISO 45001
    • BSCI
    • Sedex/SMETA
    • SA8000
    • FSC
    • GOTS
    • RoHS
    • CE-related documentation
    • industry-specific certificates

    These can be useful evidence, but they aren't a substitute for your own risk assessment.

    The OECD specifically cautions that certification and sustainability initiatives can support due diligence but cannot replace the company's own responsibility for identifying and addressing risks.

    Verify:

    Certificate → issuing organization → certificate number → scope → factory address → expiration date.

    The scope is particularly important. A certificate covering one facility or product category doesn't necessarily cover everything the supplier sells you.


    8. Audit the supply chain behind the factory

    This is where sophisticated procurement teams distinguish themselves.

    Ask:

    "Where does your material come from?"

    Not merely:

    "Can you make my product?"

    For critical materials, identify:

    Tier 1: Your supplier
    ↓
    Tier 2: Their material/component supplier
    ↓
    Tier 3: Raw-material source

    The OECD notes that significant supply-chain risks can sit beyond the direct supplier and that limiting due diligence to Tier 1 can miss important upstream risks.

    For example:

    Your electronics supplier

    → PCB manufacturer
    → semiconductor supplier
    → copper supplier
    → mineral/refining chain

    You may therefore need traceability requirements in your contract.


    9. Run a sample-development process

    Never approve a supplier solely from a catalog sample.

    A better process is:

    RFQ → technical review → sample → testing → revision → pre-production sample → pilot production → inspection → approval

    Have engineering/quality compare the sample against a controlled specification.

    Record:

    • Dimensional results
    • Material composition
    • Performance
    • Appearance
    • Packaging
    • Reliability testing
    • Failure modes
    • Deviations

    If the supplier cannot reproduce the approved sample consistently, don't move to mass production.


    10. Test their real production capability

    One of the best supplier-vetting techniques is to give multiple finalists the same RFQ and specification.

    Compare:

    FactorSupplier ASupplier BSupplier C
    Unit price$$$
    MOQ
    Lead time
    Tooling
    Capacity
    Quality score
    Audit score
    Financial risk
    Compliance
    Communication
    Payment terms
    Landed cost

    This often reveals that the lowest quoted price isn't the lowest total cost.


    11. Calculate landed cost, not factory price

    A $10 product isn't necessarily cheaper than an $11 product.

    Calculate:

    Landed Cost =

    Product price

    • tooling
    • packaging
    • inspection
    • inland freight
    • export costs
    • ocean/air freight
    • insurance
    • customs duty
    • tariffs
    • brokerage
    • destination handling
    • compliance/testing
    • expected quality losses

    Also model:

    • Currency fluctuations
    • MOQ/inventory carrying costs
    • Lead-time variability
    • Expedite costs
    • Defect rates

    This is where a Supply Chain Manager adds considerably more value than simply negotiating unit price.


    12. Conduct compliance and sanctions screening

    This depends heavily on the destination market.

    For a U.S. importer, forced-labor compliance is particularly important. CBP's June 2026 guidance consolidates enforcement under several authorities, including the UFLPA, and explicitly encourages importers to conduct supplier due diligence before importing.

    Depending on the product, screen for:

    • Forced labor
    • Child labor
    • Sanctions
    • Export controls
    • Conflict minerals
    • Environmental requirements
    • Product safety
    • Chemical restrictions
    • IP infringement
    • Anti-bribery risks
    • Country-of-origin issues

    Don't wait until Customs stops a shipment to discover that your supplier cannot document its upstream supply chain.


    13. Investigate the supplier's customers

    Ask for references from real customers.

    Ideally obtain references that resemble your business in:

    • Product
    • Volume
    • Geography
    • Quality requirements

    Ask:

    • How long have you worked with them?
    • Do they deliver on time?
    • How consistent is quality?
    • How do they handle defects?
    • How quickly do they respond?
    • Have prices changed unexpectedly?
    • Have they ever stopped production?
    • Would you use them again?

    One especially useful question:

    "What do you wish you had known before you started working with them?"


    14. Evaluate communication as part of supplier quality

    This sounds soft, but it isn't.

    During the qualification process measure:

    • Response time
    • Technical understanding
    • Accuracy
    • English/communication capability
    • Willingness to disclose information
    • Ability to understand drawings/specifications
    • Speed of corrective action
    • Escalation behavior

    If a supplier takes 10 days to answer a simple technical question during qualification, imagine what happens when a production line has a problem on Friday night.


    15. Use a weighted supplier scorecard

    For a typical industrial supplier, something like this can work:

    CategoryWeight
    Quality capability25%
    Cost / landed cost20%
    Capacity & operations15%
    Financial stability10%
    Delivery performance10%
    Compliance / ESG10%
    Engineering capability5%
    Communication5%

    Then establish automatic fail criteria.

    For example:

    • Failed factory audit
    • Fraudulent certification
    • Unacceptable forced-labor risk
    • Cannot demonstrate traceability
    • Refuses inspection
    • Materially misrepresented manufacturing capability
    • Serious IP concerns

    A supplier shouldn't be able to compensate for a compliance failure with a low price.


    16. Start small

    Don't immediately give a new Asian supplier your entire global volume.

    A safer progression is:

    Qualification

    ↓

    Sample

    ↓

    Pilot order

    ↓

    First production run

    ↓

    Performance monitoring

    ↓

    Increase volume

    ↓

    Strategic supplier status

    For a strategically important component, consider qualifying two suppliers rather than putting the entire supply chain with one factory.


    17. Put the relationship into a proper contract

    The supplier agreement should address:

    • Exact specifications
    • Approved materials
    • Quality standards
    • Inspection rights
    • Defect/rejection procedures
    • Warranty
    • Delivery requirements
    • Incoterms
    • Payment
    • Tooling ownership
    • Mold ownership
    • IP ownership
    • Confidentiality
    • Subcontracting restrictions
    • Change-control procedures
    • Traceability
    • Compliance obligations
    • Audit rights
    • Termination
    • Dispute resolution
    • Governing law

    One particularly important clause is:

    Supplier may not change materials, manufacturing location, subcontractor, tooling, process or critical component without prior written approval.

    Otherwise you can approve one factory/process and receive something materially different six months later.


    A practical "Asia supplier qualification" workflow

    I'd structure the entire process like this:

    1. Define requirements
    ↓
    2. Find 20–50 suppliers
    ↓
    3. Initial questionnaire
    ↓
    4. Legal/company verification
    ↓
    5. Commercial comparison
    ↓
    6. Compliance screening
    ↓
    7. Technical review
    ↓
    8. Factory audit
    ↓
    9. Sample + laboratory/engineering testing
    ↓
    10. Customer references
    ↓
    11. Pilot order
    ↓
    12. Pre-shipment inspection
    ↓
    13. First shipment
    ↓
    14. Supplier performance scorecard
    ↓
    15. Quarterly/annual requalification

    That is essentially turning "find me a cheap Asian supplier" into a controlled supplier qualification system.

    The biggest mistakes to avoid

    🚩 Choosing on price alone
    🚩 Assuming a marketplace badge means the supplier is trustworthy
    🚩 Never visiting/auditing the factory
    🚩 Accepting certificates without verification
    🚩 Paying a different company's bank account
    🚩 Failing to identify subcontractors
    🚩 Not testing production samples
    🚩 Ignoring Tier-2/Tier-3 suppliers
    🚩 Giving 100% of the volume to an unproven supplier
    🚩 Having no contractual change-control mechanism

    The overarching principle is "trust, but verify—and keep verifying." OECD's current framework likewise emphasizes risk-based, ongoing due diligence rather than a one-time supplier check.

    If you're doing this professionally, I'd turn the process into a 100-point supplier qualification scorecard + factory audit checklist + supplier questionnaire + red-flag checklist. That gives a Supply Chain Manager something they can actually use to qualify suppliers in China, Vietnam, India, Thailand, Malaysia, Indonesia, or elsewhere in Asia.

    Finding and vetting suppliers in Asia requires a rigorous, multi-layered approach to mitigate risks like quality drift, IP theft, communication breakdowns, and financial instability . For a Supply Chain Manager, it is a strategic process broken down into two main phases: Discovery (Finding) and Due Diligence (Vetting).

    Phase 1: Finding Suppliers in Asia (Discovery)

    Supply Chain Managers rarely rely on a single channel. A diversified sourcing strategy uses a mix of digital, physical, and network-based discovery methods:

    1. B2B Digital Marketplaces & Directories
      • Platforms like Alibaba.com and Global Sources are standard starting points for initial mapping.
      • Pro-Tip: Look past generic trading companies to find direct manufacturers by checking their business scope, machine lists, and export history.
    2. Industry-Specific Trade Fairs
      • Attending major physical exhibitions—such as the Canton Fair in China, Computex in Taiwan, or Hanoi-based manufacturing expos in Vietnam—remains invaluable . Face-to-face interaction allows managers to evaluate initial sample quality on the spot and gauge responsiveness.
    3. Local Sourcing Agents and Third-Party Consultants
      • Hiring boots-on-the-ground agents who speak the local language (Mandarin, Vietnamese, Bahasa, etc.) and understand regional business etiquette drastically cuts down search time.
    4. Peer Networks and Industry Referrals
      • Leveraging trusted logistics partners, freight forwarders, or non-competing peers in your industry often yields recommendations for factories with proven track records.

    Phase 2: Vetting Suppliers in Asia (Due Diligence)

    An online profile or shiny catalog is only an advertisement. A professional vetting process requires deep background checks across legitimacy, capability, and compliance:

    1. Legal and Business Registration Check
      • Business License Verification: Request the official local business license (e.g., a Chinese Unified Social Credit Code certificate). Check if they are registered as a manufacturer or a trading company.
      • Corporate Registry Search: Cross-reference the company name and registration number with local government databases or legal registries to check for active lawsuits, tax arrears, or bankruptcy flags.
    2. Operational and Capacity Audit
      • Factory Audit: Hire a third-party inspection agency (such as SGS, TÜV Rheinland, or AsiaInspection) to conduct an on-site audit. They evaluate shop-floor machinery, labor count, shift management, and actual production capacity.
      • Quality Management Systems (QMS): Verify authentic certifications like ISO 9001, but do not stop at the certificate copy—ask to see standard operating procedures (SOPs) and calibration records for testing equipment.
    3. Sample Testing & Prototyping (Golden Samples)
      • Order working prototypes or "golden samples." Run them through destructive and non-destructive stress testing in your home market to verify real-world material compliance and tolerance alignment.
    4. Financial and Ethical Compliance
      • Credit Health: Assess their financial stability to ensure they aren't over-leveraged or relying heavily on your upfront deposit to pay off old debts.
      • Social Accountability/ESG: Review compliance with labor laws, worker safety, fair wages, and environmental disposal regulations (e.g., WRAP, BSCI, or SA8000 audits) to protect your brand reputation.
    5. Contractual and IP Protection Safeguards
      • Ensure that before sharing detailed technical drawings or CAD files, an NNN Agreement (Non-disclosure, Non-use, Non-circumvention) tailored to the local jurisdiction (such as enforceable Chinese Mainland courts if sourcing in China) is signed by the legal entity.

    If you're currently working on a sourcing project, let me know:

    • What product category or industry are you targeting?
    • Which Asian country or region are you focusing on (e.g., China, Vietnam, India, Taiwan)?

    I can share more tailored red flags to watch out for or a sample factory audit checklist.

    Discovering and vetting new suppliers in Asia requires a mix of digital B2B directories, physical trade exposure, localized data intelligence, and third-party audit partners . Relying purely on digital storefronts leaves a supply chain manager vulnerable to trading companies masquerading as direct manufacturers.

    Top Discovery Platforms & Directories

    • Alibaba.com is the global giant for broad category coverage across China and wider Asia. Filter strictly by Verified Supplier and Assessed Supplier badges, and dig into real factory addresses and video audits rather than surface-level product listings.
    • Global Sources is heavily favored for electronics, hardware, and components. It relies on a rigorous background-check process and pairs its digital directory with massive biannual trade shows in Hong Kong.
    • Made-in-China.com is known for stringent supplier background credentials, transparent business license checks, and downloadable third-party audit reports.
    • HKTDC Sourcing (Hong Kong Trade Development Council) is an ideal channel for connecting with vetted manufacturers based in Hong Kong and mainland China, offering structured buyer-supplier matching services.
    • IndiaMART is the leading ecosystem for sourcing specifically from Indian manufacturers and alternative South Asian production hubs.

    Due Diligence & Verification Services

    • QIMA offers comprehensive on-the-ground supplier audits, ethical inspections, and laboratory product testing across Asia to verify factory capabilities before signing contracts.
    • SGS provides independent corporate and factory evaluations, verifying compliance with international quality, environmental, and labor standards.
    • Local Business Registry Checks: For China, cross-referencing a supplier's Unified Social Credit Code via the National Enterprise Credit Information Publicity System confirms registered capital, legal status, and administrative penalties.

    Specialized Sourcing & Regional Agents

    When remote validation isn't enough, local sourcing agencies can physically inspect shop floors, check sub-tier supplier networks, and manage contract execution transparency. Top firms include:

    • Dragon Sourcing (multinational procurement and spend management across Asia)
    • Jing Sourcing (popular for mid-market manufacturing and oversight in China)
    • MoveToAsia (specialized in scaling supply chains across Vietnam and Southeast Asia)

    If you'd like to narrow this down, please share:

    • What product category or industry (electronics, apparel, heavy machinery, etc.) are you sourcing for?
    • Are you focusing strictly on China , or expanding into Southeast Asia / South Asia?

    I can provide a more tailored blueprint or specific compliance checklists for your sector.

    Best resources for discovering and vetting Asian suppliers

    For a supply chain manager, the strongest approach is to use supplier-discovery platforms to build a shortlist, independent data sources to verify the companies, and on-the-ground audits to validate their actual capabilities. No marketplace badge, certificate, or supplier-provided document is sufficient on its own.

    I’d organize the process into five stages: discovery, legal and financial verification, compliance screening, factory validation, and ongoing risk monitoring.

    1. Best supplier-discovery resources

    These are the platforms I’d use first, depending on the country, product category, and level of supplier maturity you need.

    These platforms serve different purposes. Using two or three complementary channels is generally more useful than relying on a single directory. A comparative review of Asian sourcing marketplaces also identifies differences in regional coverage and verification depth.

    My recommendation: Start with Alibaba plus one category-specific or regional source. For high-value, complex, or business-critical components, supplement online discovery with trade-fair exhibitors, referrals from existing suppliers, and local sourcing specialists.

    2. Best resources for supplier due diligence

    These are the resources I would prioritize before approving a new supplier, especially one receiving a significant purchase order or advance payment.

    A. Verify the legal entity and ownership

    • China: National Enterprise Credit Information Publicity System — check the exact Chinese legal name, unified social credit code, registration status, business scope, and registered address.
    • Across Asia-Pacific: AsiaVerify — a commercial research option for registry data, ownership connections, court records, and other risk indicators. Confirm which jurisdictions and records are covered for your target supplier.
    • Southeast Asia: ASEAN Trade Repository — useful for country-specific trade rules and regulatory research, though it is not a universal corporate registry.

    Check: Does the legal name on the business license match the contract, invoice, bank-account beneficiary, and audit report? Is the supplier a manufacturer, trading company, or both?


    B. Screen sanctions and regulatory risks

    Check: Screen the supplier's legal name, aliases, relevant owners and intermediaries, and other transaction parties as appropriate. Investigate potential matches rather than assuming similar names are definitive matches. Assess applicable U.S. and other jurisdiction-specific requirements.


    C. Validate certifications and quality systems

    • IAF CertSearch — verify accredited management-system certifications, such as ISO 9001, where available.
    • ISO certification guidance — understand how certification bodies and accreditation affect the credibility of a certificate.

    Check: Confirm the certificate number, issuing body, validity, covered site, and scope. An ISO 9001 certificate is evidence of a quality-management system, not proof that every product will meet your specifications.


    D. Arrange independent factory audits and inspections

    • SGS — supplier audits, inspections, testing, and verification services.
    • Bureau Veritas — supplier qualification, factory assessments, and quality and compliance services.
    • Intertek — product testing, inspections, and supplier assurance.

    These are established third-party service providers. Scope, geographic coverage, and available audit programs vary by country and product.

    Check: Verify the production site in person or through a qualified independent auditor. Examine production equipment, capacity, quality-control records, traceability, subcontracting, labor conditions, and corrective-action procedures.


    E. Cross-check real-world trading activity

    • Panjiva and ImportGenius — commercial trade-intelligence resources that can help identify shipment activity, trading relationships, and potential sourcing leads where records are available.
    • ASEAN Trade Repository — consult country-specific customs rules, origin requirements, and trade procedures.

    Check: Compare the supplier's claimed export history, product range, capacity, and customer references against independently available evidence. Trade data can be incomplete, and absence of a shipment record does not establish that a supplier is illegitimate.

    3. The due-diligence workflow I recommend

    The most effective process is risk-based: perform inexpensive desktop checks on every candidate, then spend more on the suppliers that could materially affect your business.

    Step 1 — Build the longlist

    Initial screening

    Identify 10–20 potential suppliers using two or more sourcing channels. Send the same RFQ, technical specification, forecast volumes, and quality requirements to each candidate.


    Step 2 — Verify identity and documentation

    Desktop due diligence

    Obtain the legal registration details, factory address, ownership information, relevant certifications, bank details, customer references, and disclosure of subcontractors. Cross-check these independently.


    Step 3 — Assess financial, legal, and compliance risk

    Risk screening

    Screen sanctions and adverse information, investigate ownership concerns, review available financial or credit reports, and map product-specific regulatory and forced-labor exposure.


    Step 4 — Validate capability

    On-site and technical validation

    Audit shortlisted factories, validate samples, conduct product testing, verify production capacity, and inspect traceability and quality systems. Require a corrective-action plan for material gaps.


    Step 5 — Approve with controls

    Qualification and onboarding

    Start with a controlled pilot order, use contractually defined specifications and acceptance criteria, establish appropriate payment protections, and monitor delivery, defects, corrective actions, and compliance over time.

    4. Supplier qualification scorecard

    I recommend using a weighted scorecard so sourcing decisions are comparable across countries and procurement categories.

    Illustrative thresholds

    This is a prioritization aid, not a compliance certification. A strong overall score must never override a confirmed sanctions issue, material fraud concern, critical quality failure, or other mandatory disqualifier.

    [Reset scores]

    For critical components or sole-source suppliers, I would raise the requirements for financial resilience, business continuity, process controls, and sub-tier visibility. For low-risk, easily replaceable items, a lighter qualification process may be proportionate.

    5. Common red flags to investigate

    Warning signRecommended response
    Supplier refuses to provide its legal registered namePause qualification until identity is verified
    Contracting entity and bank beneficiary differIndependently verify the relationship before payment
    Factory address cannot be reconciled with the audit reportArrange independent site verification
    Prices are far below competing quotesCheck specification differences, capacity claims, and fraud risk
    Certifications cannot be independently verifiedTreat the relevant capability as unverified
    Supplier will not disclose material subcontractingAssess traceability and operational control risks
    Unexpected changes to payment instructionsVerify through a known, independent communication channel
    Repeated quality failures or unrealistic lead timesRequire corrective action and validate capacity before scaling

    6. Which resources should you invest in first?

    My practical shortlist would be:

    For every new supplier: marketplace discovery, official company registry checks, applicable sanctions screening, certification verification, and reference checks.

    For strategic or higher-risk suppliers: independent factory audits, commercial credit reports, ownership and adverse-media research, and shipment intelligence where available.

    For complex or regulated supply chains: specialized labor and ESG assessments, product testing, origin and sub-tier traceability, and professional legal or trade-compliance advice where warranted.

    The key is to distinguish supplier discovery from supplier approval. A directory helps you find candidates; independent evidence and physical validation establish whether they are suitable to do business with.
