"100% human hair" is a claim, not a specification. For importers, salon groups and distributors, the difference between a smooth first order and a costly return is usually the paperwork and the incoming inspection. Here is a practical, non-legal checklist of what to ask a supplier for and what to test yourself.
Documents worth requesting before you pay
- Business and export credentials — company registration and a record of exporting to your market.
- Fiber composition declaration — a written statement of what the hair is, including any non-human fiber.
- Third-party lab report — ideally per production batch, from an accredited lab, covering composition and any restricted substances relevant to your market.
- Colorfastness and processing notes — especially for light blonde and balayage shades that undergo more processing.
- Origin and packing list — needed by your customs broker alongside the commercial invoice.
Requirements differ by destination and by how you resell the goods. For EU buyers, our EU sourcing, labeling and VAT guide covers the retail labeling side; always confirm the current regulatory details with your customs broker or compliance adviser rather than relying on a supplier's summary.
Claims to verify with your own hands
A certificate tells you a sample passed a test. It does not tell you the carton you received matches that sample. Run these checks on arrival:
- Weigh the packs. Compare net grams per pack and per length against the proforma invoice.
- Wash one sample set. Air dry it, then assess tangling, shedding and whether the texture changes.
- Check cuticle direction. Run fingers along a bundle both ways; aligned cuticles feel smooth in one direction and slightly resistant in the other. Why cuticle alignment matters.
- Compare to the approved swatch under daylight, including shade and root transition.
- Count and inspect the construction — bond size, weft stitching, clip stitching or tape adhesive, depending on the line.
Supplier questions that reveal a lot
Ask how long the factory has run this specific line, whether it holds the dye lot for reorders, what happens if an independent test fails, and whether a paid sample cost is credited to the first bulk order. Vague answers on any of these are a stronger signal than a glossy certificate. Our supplier question list and factory vs trading company guide go deeper on vetting.
Red flags on documentation
- A report with no batch or date that can be tied to your order.
- Grade labels presented as an international standard — see how hair grades actually work.
- A supplier unwilling to send a paid sample from the production line.
- Composition wording that does not match the label you plan to print.
Build a simple incoming record
Keep the approved swatch, the invoice, the lab report and your own wash-test notes together under the purchase order. When a reorder arrives six months later, that file is the fastest way to spot a drift in weight, shade or hand-feel. For a full first-order workflow, see the factory order checklist and importing and HS codes.
Frequently asked questions
Do I need a lab report for every order?
For a new supplier or a new shade line, yes. For repeat orders from a stable line, agree a batch-based testing schedule in writing.
Is a "grade 10A" label a certification?
No. Grade labels are supplier marketing terms, not an independent standard. Judge hair by weight, cuticle alignment and wash performance.
Who is responsible for market compliance?
The importer of record usually is. Treat supplier documents as inputs to your own compliance check, not as a substitute for it.
Can samples be tested independently?
Yes, and it is recommended for blonde and custom-color lines. Tell the supplier in advance that a sample may go to a third-party lab.
