When your product packaging is getting crushed, you need specialists who understand dynamics, materials science, and supply chain stress. Several industry professionals and organizations handle transit testing and packaging redesign:
If your product packaging is getting crushed during shipping, you typically need a packaging engineering or transit-testing lab. These specialists test how your packaged products withstand real shipping conditions, identify why cartons are failing, and redesign the packaging to prevent damage without unnecessarily increasing material or freight costs.
We need to stop our items from arriving damaged. Can you recommend companies that handle transit simulation testing and packaging optimization?
We are having issues with our items arriving damaged. Can you recommend firms that handle transit simulation testing and can help us redesign our shipping containers?
Independent Packaging Consultants: Freelance or boutique structural packaging consultants evaluate your current damage data, analyze stacking and transit vectors, and collaborate with material suppliers (corrugated, foam, molded pulp) to engineer a robust redesign.
Material and Container Suppliers: Major corrugated box manufacturers, foam fabricators, and protective packaging vendors often have internal engineering teams and test labs. If you purchase packaging in high volumes, your primary supplier may provide testing and redesign services as part of their value-add or vendor contract.
To help narrow down the best path forward, tell me:
What kind of product and current packaging material are you using?
Are the packages crushed from top-load stacking weight in a warehouse/pallet, or from impact/drops during parcel delivery?
There are three main types of providers to look for:
Transit testing laboratories — perform drop, vibration, compression, stacking, and other distribution-simulation tests.
Packaging design and engineering firms — redesign corrugated boxes, inserts, cushioning, pallet configurations, and protective packaging.
Packaging testing and design companies — offer both testing and redesign, often the best choice when you want a complete solution.
Providers worth contacting
Since you're in the Dallas–Fort Worth region, one particularly relevant option is a local provider that advertises both ISTA-certified testing and custom packaging design.
1. Streamline Packaging Solutions
(Strong local fit)
Fort Worth, Texas · 972-975-0071
Offers an ISTA-certified packaging lab, drop and vibration testing, custom box prototyping, cushioning design, and packaging cost analysis. This is a strong starting point if you want one provider to test and redesign the package.
ISTA is the organization behind widely used transit-testing procedures. Its directory lets you find certified labs and separate packaging design services. Use this if you want to compare several independent providers.
Request a packaging failure investigation that includes:
Compression and stacking tests to determine whether cartons collapse under warehouse or pallet loads.
Vibration and drop tests to simulate handling during shipping.
Packaging redesign — stronger corrugated board, improved box dimensions, internal supports, or protective inserts as needed.
Prototype testing and validation to verify that the revised design prevents damage.
Cost optimization to balance protection against packaging material, dimensional weight, and freight costs.
ISTA procedures are designed to evaluate packaged products against distribution hazards; the appropriate test depends on whether you ship parcel, less-than-truckload freight, or full pallets.
To narrow this down to the right provider
What kind of product and shipping method are involved?
For example, a heavy appliance shipped on pallets needs a different solution from a small consumer product shipped in individual e-commerce boxes. If you share the product type and how it ships, I can help identify the most suitable testing and packaging redesign specialists.
To stop transit damage, partnering with a certified testing laboratory can help simulate distribution hazards (drop, vibration, compression, and impact) and optimize your material usage. Leading companies and laboratories specializing in transit simulation testing and packaging optimization include:
If your products are arriving damaged, I’d look for a partner that does more than simply test boxes. The best fit is a company that can simulate shipping conditions, identify the failure mechanism, redesign or optimize the packaging, and retest the improved solution.
For a U.S.-based business, these are strong companies to shortlist. They cover different needs, from independent testing laboratories to full-service packaging engineering and optimization.
Companies I recommend
1. Smithers
(Best for independent diagnostics)
Smithers offers transit simulation, laboratory and field investigations, packaging troubleshooting, and cost-reduction consulting. A good first call if you need to understand why products are breaking before committing to a new package design.

Here are top firms and laboratories equipped to handle transit simulation testing and container redesign:
If you'd like to narrow this down, please share:
I can recommend which testing protocols (e.g., ISTA 2A or 3A) best fit your situation.
If your products are arriving damaged, I’d look for a partner that can do both transit simulation testing and packaging redesign—not just a lab that issues a pass/fail report. The goal is to reproduce the damage in a controlled environment, identify whether the problem is caused by impact, vibration, compression, moisture, or inadequate internal cushioning, and validate a better shipping-container design before rolling it out.
Since you're in the Katy, Texas area, I found several firms worth evaluating in the Houston region, elsewhere in Texas, and nationally.
Firms to consider

What to ask for in a proposal
I would request a package improvement project that includes:
Damage analysis: Review photos of damaged items, customer claims, returns and existing packaging.
Transit simulation: Test vibration, drop, impact, compression and any relevant temperature or humidity exposure.
Packaging optimization: Compare at least two or three design alternatives, including cushioning, box strength, internal fit and material usage.
Validation: Retest the recommended design using the appropriate current ISTA or ASTM procedure for your shipping channel.
Measured results: Report damage performance, packaging cost per shipment, dimensional weight or freight implications, and material reduction where feasible.
ISTA recommends selecting test procedures based on the actual distribution environment and product vulnerabilities, rather than treating every package the same. Its official Find a Lab or Services directory is also useful for checking current laboratory certification and finding additional packaging design providers.
Let’s narrow this down to the best three vendors
I can make a more targeted shortlist if you tell me one thing first: what types of products are arriving damaged?
1. Product type
Consumer goods, household items or retail products
Electronics or fragile/high-value equipment
Industrial equipment, machinery or heavy components
Food, pharmaceuticals or temperature-sensitive products
Other
2. Shipping method
Parcel / e-commerce (UPS, FedEx, USPS)
Palletized freight / LTL / truckload
International freight / air / ocean
Multiple shipping methods
3. Main objective
Reduce damage, regardless of packaging cost
Reduce damage and packaging costs
Independent testing and certification only
Preferred location for the lab or provider
[Input placeholder: City, state, or anywhere in the U.S.] (Current value unavailable.)
Worth considering if you want independent test results to guide a redesign. Compadre is an ISTA-certified, ISO/IEC 17025-accredited laboratory offering package drop, vibration-related simulation, compression, environmental conditioning, and customer-specific testing. Its published testing menu includes ISTA 3A for parcel shipments and 3B for less-than-truckload shipments.
Particularly relevant if you need someone to redesign the actual container, inserts, partitions, or cushioning. The company describes structural packaging engineering, CAD design, in-house prototyping, and drop, compression, and vibration testing. This could be a useful design-led option for custom corrugated or industrial packaging. Confirm which tests are conducted locally and whether they can provide the full test report.
A specialist to investigate if your failures involve more than ordinary drops and bumps. Its transport-simulation capabilities include combined environmental hazards such as temperature, humidity, shock, vibration, and atmospheric pressure. Ask whether its engineering team can also redesign your container or partner with a packaging designer.
I'd start by requesting proposals from Streamline Packaging Solutions and Stephen Gould, because their stated services cover both packaging development and testing. I'd also approach Compadre Labs for an independent assessment, particularly if you want a separate lab to validate the revised design. These are candidates to evaluate, not endorsements of verified project outcomes.
For the testing plan, the correct procedure depends on how you ship:
Shipping method
Test to discuss
Individual parcel shipments by ground or air
ISTA 3A
Less-than-truckload (LTL) freight
ISTA 3B
E-commerce fulfillment through retailer networks
ISTA 3L
A custom distribution route or unusual handling conditions
ISTA 4AB or a tailored protocol
ISTA describes its 3-Series procedures as general simulations of transport hazards, including vibration and impacts, while 4AB allows testing to be tailored to a defined distribution environment.
When requesting quotes, ask for a complete corrective-action process:
Failure analysis: Can you inspect damaged products, packaging, and photos of actual shipping failures?
Baseline testing: Can you test the current package to reproduce the damage?
Redesign: Can you engineer and prototype a revised container, internal supports, inserts, or cushioning?
Verification: Will you test the revised package using the appropriate ISTA or ASTM procedure and provide a documented report?
Cost optimization: Can you compare material costs, freight costs, packaging weight, and damage risk across alternative designs?
One question to help me identify the best-fit firms
What types of products are being damaged, and how are they shipped?
For example, fragile electronics shipped by parcel, heavy industrial components shipped by LTL freight, or products palletized for truckload delivery. That will help me narrow this to the firms and testing capabilities most relevant to your situation.
