Every wholesale buyer eventually asks the same question: is this company actually a factory, and will what ships match what I approved? This guide is the checklist we hand to buyers ourselves — because a buyer who verifies properly has fewer disputes, and disputes are what kill long-term orders.
Step 1 — Factory or trading company? (Ask the wrong question and you learn nothing)
Asking "are you a factory?" gets a yes from almost everyone. Ask instead:
- "Which factory does the cutting and sewing for this style?" — a real producer names its lines and can put you on a video call with the floor.
- "Can I see the business licence scope?" — Chinese licences state whether the entity is manufacturing or trading.
- "Where is the fabric sourced?" — a factory knows its mill; a reseller knows its price list.
Being a trading company is not a disqualifier — we operate as a manufacturer-and-export partner with dedicated production lines, and many of the best quality controllers in the market are trading companies that sit between you and several factories. What matters is that the company owns the quality outcome and says honestly what it is.
Step 2 — Judge the first sample like a buyer, not a guest
The sample is the factory's real resume. Check in this order:
- Weigh it. A kitchen scale tells you if the "320 gsm fleece" is actually 320. Fabric weight is the single most faked spec in pet apparel.
- Measure the chest and back against the size chart. If the garment ignores the chart the factory itself sent, nothing else on paper is trustworthy.
- Look inside. Finished seams, covered raw edges, bar-tacks at stress points (leg openings, harness slots), consistent stitch density. Inside photos reveal more than outside ones.
- Test the hardware. Zipper runs ten times without catching; snaps don't pop under a firm tug; D-rings are welded or riveted, not glued.
- Wash it once. Colour bleed or pilling after a single wash predicts returns after ten.
Step 3 — Verify the fabric claims in writing
Ask for a material declaration listing fibre composition per layer (shell / membrane / lining / filling). Reputable suppliers provide it because their own compliance depends on it. Then spot-check: burn-test a scrap (polyester melts and beads; nylon melts and drips with a celery-like smell; cotton chars and ashes). It takes two minutes and catches the classic "wool blend" that is 100% acrylic.
Step 4 — Ask to see the QC process, not just the QC promise
Everyone says "we do strict quality control." Useful questions:
- Is there in-line inspection (during sewing) or only final inspection?
- What is the AQL on final inspection? (Normal trade goods: 2.5 major / 4.0 minor.)
- Do you provide a per-size measurement sheet from the production batch? (Not the sample — the batch.)
- Will you send pre-shipment photos of actual cartons with our PO numbers visible?
If the answers are vague, the control is vague.
Step 5 — Welcome a third party
SGS, TÜV, BV and Intertek all do per-order inspections in China for a few hundred dollars. A supplier who resists third-party inspection is telling you something. A supplier who offers to share the inspection report before you pay the balance is telling you something else. We expect buyers to use inspectors and build the report into the payment schedule.
Step 6 — Stress-test communication on a small order first
Place a deliberately small first order (100–300 pcs) and measure: quote turnaround, answer time on a change request, honesty when something goes wrong, and whether shipping documents arrive before the cargo does. The first order is a paid test of the second order.
Step 7 — Structure payment so both sides have skin in the game
The normal, defensible structure is a deposit (typically 30%) and the balance after inspection passes (70% before shipment). Be cautious of anyone demanding 100% upfront before production, and equally cautious of "balance after delivery" offers from unknown parties — the cost of a bad factory is never zero, it just moves.
The one-line version
Verify the fabric with a scale, verify the process with questions, verify the people with a small first order, and let a third party verify the batch. Any manufacturer confident in its work will help you do all four.
