How to Vet an Overseas Clothing Manufacturer: A 12-Point Checklist

Most brands pick their first apparel manufacturer through a personal referral, a LinkedIn intro, or a trade show. That's fine as a starting point — but "someone I trust said they're good" is not vetting. Vetting is a specific set of questions with specific answers, followed by specific verification steps.

Here's the checklist we wish more founders used before signing a production agreement.

1. Is there a current, credible social-compliance audit?

Ask for the audit report, not just the certificate. You want to see findings, corrective actions, and renewal date. A factory confident in its compliance will share the full report; one that shares only the certificate is hiding the findings.

Credible audit bodies for apparel: SMETA, SA8000, WRAP, BSCI. If the factory holds a Fair Trade USA or GOTS certification, those include social audits as well.

2. Does their certification actually match your claims?

If you're selling "organic cotton" on your hang-tag, the factory needs to be GOTS-certified for the specific processes your garment goes through (stitching, printing, packing — not just the fiber). If you're claiming "Fair Trade," the factory must hold Fair Trade USA or Fairtrade International certification and be willing to pay the premium into the worker fund.

A factory with GOTS can't automatically make a Fair Trade-labeled product. Different audits, different labels.

3. Will they share reference clients?

A factory producing for real brands can name them (with permission). Ask for 2-3 reference clients in your size bracket and ideally your category. Actually call them. Ask: "How has the factory handled mistakes? How's communication? Would you use them again?"

4. What's their MOQ — and what happens below it?

Get MOQ in writing, along with per-piece cost at 500 / 1,000 / 2,000 / 5,000 units. The shape of the quantity curve tells you how their economics actually work. Steep curves mean they're subsidizing your small order to win the business; shallow curves mean they're set up for your quantity range.

5. Who is the factory of record?

Ask this explicitly: "If I send you 1,000 units of production, are you making them yourself, or are you subbing part or all of it to another factory?"

Sub-contracting is legal and common. It becomes a problem when:

• The sub-contractor doesn't hold the same certifications
• You're not told
• Quality control at the sub is weaker

Ethical factories disclose sub-contracting upfront. Sketchy ones don't.

6. What are the payment terms?

Standard in apparel: 30% deposit with the PO, 70% balance against shipping documents (before or upon shipment). Variations exist (50/50, milestone payments on sampling + bulk + shipping). If a factory is demanding 100% upfront, walk.

Watch also for currency clauses: are you locked to a specific exchange rate, or exposed to currency movement between PO and shipment?

7. What's the sampling timeline and cost?

Expect $40-100 per sample depending on complexity, with 2-3 revision rounds typical. A factory that quotes "free samples" at MOQ levels below 1,000 units is either sloppy, overpromising, or absorbing sampling cost into per-piece pricing (i.e. you pay for it anyway).

8. How do they do quality control?

Good factories have:

• Inline QC — stitch operators do self-checks and first-piece approvals each shift
• End-of-line QC — trained inspectors check finished garments
• Final inspection at an agreed AQL level (2.5 is standard, 1.5 is strict)

Great factories also accept third-party inspection pre-shipment (SGS, QIMA, Bureau Veritas) without flinching.

9. Communication cadence and point of contact

You want a named account manager, ideally fluent in the language you operate in, reachable by a channel that fits your workflow. Test the cadence during sampling: if responses take 48 hours during sampling, they'll take a week during production.

10. What's their compliance with your destination market?

• California Prop 65 (if selling into CA) — chemical disclosure
• EU REACH — restricted substances
• US CPSC — children's product safety if applicable
• EU CSRD / German LkSG — supply-chain due diligence reporting

A factory that produces regularly for US or EU buyers will know these. A factory that doesn't will look blank when you ask.

11. What happens if you pull the order mid-run?

Unlikely but possible. Standard answers:

• Cancellation before fabric is purchased: full refund of deposit minus sampling costs
• After fabric is purchased but before cutting: deposit forfeit, no further liability
• After cutting: pay for materials and WIP (work in progress)
• After stitching: pay for the whole order

Get the answer in writing.

12. Is the factory willing to host an on-site visit?

Serious ethical factories welcome visits. They schedule a tour, introduce you to management, let you walk the floor. A factory that resists in-person visits after you've committed to an order is a red flag.

If you can't visit personally, an agent visit or a third-party factory audit (Sedex, SGS) serves the same purpose.

Using the checklist

Don't run all 12 as a single interrogation email; that doesn't work. Instead:

• Before the first quote request: confirm 1, 2, 4 (compliance, certification match, MOQ)
• During quote discussion: 3, 5, 6, 7 (references, factory of record, payment, sampling)
• Before the PO: 8, 9, 10, 11 (QC, communication, destination compliance, cancellation)
• Before first bulk shipment: 12 (visit or third-party audit)

Pace it. Factories that pass each stage are factories worth producing with.
