The 7-Point Factory Verification Checklist

1. Registration numbers, not logos

Ask for the FDA facility registration number and CE technical file reference, then verify them yourself on the FDA / issuer databases. A logo on a website proves nothing.

2. Batch-level documents

MSDS, COA and REACH for your exact SKU, per batch. If the supplier only shows one generic PDF for "the company", that's a warning.

3. Test samples yourself

Order samples and test adhesion on your own skin, spring-band tension, and packaging quality. Real factories ship samples fast; middlemen often stall.

4. Spot the trading company

Red flags: no physical factory address, refuses video audits, certificate names don't match the company, price suddenly jumps when you ask for documentation, or the "factory" is actually an office in a city far from any production line.

5. Payment safety

Use T/T with a deposit + balance against documents, or L/C for larger orders. Avoid 100% advance to a personal account. See our Trust & Payment Safety page.

6. Third-party audit

SGS, BV or TÜV can audit the factory on your behalf. A factory that welcomes audits is a factory with nothing to hide.

7. Visit or video call the line

A live video walkthrough of the production line is the cheapest audit you can do. Serious factories (like HLK) will happily arrange it.

What a Verified Factory Looks Like (We're the Example)

  • Batch COA / MSDS / REACH provided with every shipment.
  • 3,500 m² facility, 5 automated lines, in-house R&D — we are the manufacturer, not a trading office.
  • Factory visits and third-party audits welcome — our customers have filmed and audited our lines (see the factory tour).
  • Payment terms structured for buyer protection (deposit + balance against documents).

Factory Verification FAQ

How can I check if a factory's FDA registration is real?
Search the FDA Establishment Registration & Device Listing database with the facility number. Cross-check the registered name and address against the company you are dealing with.
How do I know if a supplier is a factory or a trading company?
Ask for a live video walkthrough, a business license showing "manufacturing", physical factory photos with identifiable machinery, and batch-level test documents. Trading companies typically cannot produce per-batch COAs or walk a production line.
What payment terms are safest for first orders?
A 30–50% deposit with the balance paid against shipping documents, or L/C for larger amounts. Avoid 100% advance to personal accounts. HLK offers deposit + balance-against-documents terms.
Does HLK allow third-party audits?
Yes. SGS, TÜV, BV or your own auditors are welcome. Several HLK customers have visited the factory and filmed the production lines.
