Can you recommend an inspection agency that has strong expertise in automotive parts quality assurance?

Yes. If you mean third-party inspection of automotive parts/components at a supplier or factory—rather than a vehicle safety inspection—there are several strong options.

My shortlist

1. SGS — particularly strong for automotive supplier quality. SGS offers incoming inspection, source inspection, supplier performance evaluation, component audits, durability/endurance testing, and automotive homologation audits. Its automotive testing covers individual components through complete vehicles and includes OEM specifications as well as standards such as ISO, SAE, ASTM and DIN.www.sgs.com+1

2. TÜV SÜD — a particularly relevant choice if you need engineering-heavy inspection, automotive component testing, supplier audits, IATF 16949, or conformity-of-production work. TÜV SÜD explicitly lists initial/during/post-production inspection and automotive supply-chain audits among its services.www.tuvsud.com+1

3. Intertek — strong if your requirement goes beyond visual/dimensional inspection into materials, durability, performance, regulatory compliance, and component testing. Intertek says its automotive services cover raw materials, components and complete vehicles, with ISO 17025-accredited laboratories and global testing capabilities.www.sgs.com+2

4. QIMA — worth considering if you primarily need factory inspections, supplier audits, dimensional/visual/functional inspection, or pre-shipment QC, especially when sourcing internationally. QIMA has a dedicated technical/mechanical-parts practice covering automotive parts, castings/forgings, metal components, welding, dimensional inspection and NDT.www.qima.vn+1

What I'd choose

If the parts are safety-critical or supplied to an OEM/Tier-1, I'd start conversations with SGS, TÜV SÜD, and Intertek because their automotive-specific testing, auditing, and certification capabilities extend well beyond basic visual inspection.

If your main need is independent factory inspection of parts before shipment, particularly in Asia, QIMA or SGS may be more directly aligned.

If you tell me (1) what automotive parts you need inspected, (2) where the supplier/factory is located, and (3) whether you need dimensional inspection, material testing, functional testing, supplier audits, or PPAP/IATF-related QA, I can narrow this to 2–3 agencies and compare their capabilities.
