Finding a good factory for your clothing brand is never easy, but sourcing knitwear comes with its own unique challenges. Unlike cut-and-sew garments, sweaters are made from scratch using yarn. The factory you choose needs to understand yarn types, knitting gauges, and finishing techniques — not just operate a sewing line.
A knitwear manufacturer checklist is a list of questions that covers factory background, machines, yarn, sampling, MOQ, QC, lead time and contract terms. Use it before you commit to sampling or bulk production. It takes about 30 minutes to go through, and it filters out most factories that will waste your time or money.
Here is the short version. Ask about: who owns the factory and how long it has run, what machines and gauges it has, how it sources yarn, how sampling works, what the MOQ is per style/color/size, how QC and inspection work, what the real lead time is, and how you will communicate during production. If a factory answers all of these clearly, you have a workable partner. If answers are vague, walk away.
Why a checklist matters before you order knitwear
Knitwear is not like cutting and sewing a woven garment. The yarn, the machine gauge, the stitch structure and the finishing all decide the final product. A mistake in any of them shows up in the finished sweater, not in a spec sheet.
Most problems brands hit with a factory fall into the same patterns: the MOQ was higher than expected, the gauge came out wrong, the yarn substitution changed the handfeel, the sample looked fine but bulk looked different, or the lead time slipped by weeks. Every one of these was visible before the order if someone asked the right question.
A checklist forces both sides to be specific. “We do quality control” tells you nothing. “We run a final inspection on 100% of garments and use AQL 2.5 on random lots” tells you something real.

Factory background and credentials
Start with the basics. These questions establish who you are actually dealing with.
1. Are you the factory or a trading company? This is the first question for a reason. Many “manufacturers” in China are trading companies that pass orders to factories. That is not automatically bad, but it adds a layer between you and production. If you want direct control, ask for proof: factory name, address, photos of the workshop. If you would rather start with a factory you can verify, see our custom knitwear manufacturer page and the OEM vs ODM in knitwear manufacturing breakdown.
2. How long have you been making knitwear? Look for years of actual knitwear production, not years in business. A company can trade garments for a decade and still be new to knitting.
3. What is your monthly production capacity? Ask in pieces per month for knitwear, and how many machines that represents. Compare it to your order size. A factory doing 200,000 pieces a month can handle your 2,000-piece order easily. A factory doing 5,000 pieces a month cannot.
4. What gauges do you run? A good knitwear factory covers a range, typically from coarse (3GG, 5GG) to fine (12GG, 14GG, 16GG). If your product needs 7GG and the factory only runs 12GG, they will either outsource or push you to a different gauge. Both change your product.
5. Who are your current clients? You don’t need names. You need to know the factory works with brands in your market and at your quality level. Ask what kind of products they make most: men’s, women’s, kids’, basic or fashion styles.
6. Can you show me your business license and export experience? A factory that exports regularly can answer questions about incoterms, export documents and shipping without hesitation. If they hesitate, your shipment will be the first one they figure out.
Machines and production capacity
Machines decide what the factory can actually make. Ask specific questions, not “what can you do?”
7. What knitting machine brands and types do you have? Flat knitting machines (Stoll, Shima Seiki or Chinese brands like Jinlong) all knit differently. Ask what they run. This also tells you if they can do shaped knitting or mostly cut-and-sew panels.
8. How many machines per gauge? One 12GG machine is not “we do 12GG.” Ask how many machines run each gauge. This affects how fast your order moves and whether they can handle your quantity in one run.
9. Do you do fully fashioned or cut and sew? Fully fashioned knitting shapes the garment on the machine. Cut and sew knits panels and cuts them. They look and fit differently, and cost differently. Know which one you are buying.
10. What finishing and linking equipment do you have? Linking (joining knitted panels) is the step where quality lives or dies. Ask if they do it in-house. A factory that outsources linking loses control of a critical step.
11. Can you handle trims, embroidery and other decoration in-house? If your design needs embroidery, prints or special buttons, find out now whether it’s in-house or subcontracted. Subcontracted work adds lead time and another QC gap.
Yarn and materials
Yarn is the biggest cost and the biggest variable in knitwear. Nail it down early.
12. Do you source yarn for me or do I supply it? Most factories can source yarn. Ask who they buy from and whether they can show yarn mill names. If you supply yarn, confirm they can handle your yarn and who is responsible if it arrives late.
13. What yarn counts and compositions can you run on your machines? Not every yarn runs on every gauge. A 2/48Nm wool runs fine on 12GG; a thick boucle needs a coarse gauge. Ask what they have actually knit, not what they claim. Our yarn count and machine gauge matching guide explains how this pairing works.
14. Can you match a specific yarn? If you have a reference yarn from a brand or a mill, ask whether they can match it: count, twist, fiber blend, color. Yarn matching is a real skill and takes samples.
15. How long does yarn sourcing and dyeing take? Stock yarn is fast. Custom-dyed yarn adds 2–4 weeks depending on the mill. This is a lead time question disguised as a yarn question.
16. What happens if yarn is defective or short? Ask about yarn shrinkage, dye lot differences and who carries the risk. Good factories check yarn before production and flag issues early.
Sampling and development
Sampling is where you learn how the factory works. It is also where most miscommunication shows up.
17. How long does a sample take, and how many rounds are included? A typical knitwear sample takes 7–10 working days. Ask what happens if the first sample is wrong. Are revisions free? Up to how many? Who pays for yarn and labor on the second sample?
18. Do you make a fit sample, a strike-off, or both? For knitwear, a gauge swatch (strike-off) is cheap and fast. A full garment sample is slower. Ask which you get first and whether you can approve the swatch before the full sample.
19. What do you need from me to start sampling? A tech pack, a sketch, a reference garment, or just a description? Ask what format they prefer. This tells you how professional their development process is.
20. Can you grade sizes from one sample? Confirm they can produce size grading (S–XL or your size range) from a single approved sample, and whether grading is included or charged.
MOQ, pricing and payment
Money questions are the ones people avoid, and the ones that cause the most pain later.
21. What is your MOQ per style, per color and per size? These are three different numbers. A factory may say “100 pieces” but mean 100 pieces per style, with minimums per color and per size on top. Get the real structure. Low-MOQ knitwear production in Dalang changes the math for small brands.
22. How do you price: FOB, EXW or CIF? Know what the price includes. Ask for a breakdown of yarn cost, knitting cost, finishing cost and trims. A factory that can break down its price understands its own costs. One that can’t is guessing.
23. What is your payment schedule? Typical terms are a deposit (30–50%) before production and balance before shipment. Ask about payment methods: T/T, L/C, PayPal. Confirm what happens to your deposit if production fails.
24. What happens if bulk production deviates from the sample? Ask how they handle defects, color differences and sizing issues in bulk. Do you get a discount, a re-run, or a refund? Get the answer in writing.
Quality control and inspection
QC is not a checkbox. It is a process. Ask how it actually works.
25. What QC checks happen during production? A serious factory checks yarn on arrival, knitting in progress, finishing, and does a final inspection before packing. Ask for the stages. Ask if you can send a third-party inspector (SGS, Bureau Veritas, or your own QC) to the factory.
26. What is your acceptable defect rate? AQL (Acceptable Quality Limit) 2.5 is common for knitwear. If a factory won’t name a number, that’s an answer in itself.
27. How do you handle defects found at final inspection? Confirm the factory repairs, replaces or refunds defective pieces, and who pays for the re-inspection.
Lead time and logistics
28. What is your lead time from sample approval to delivery? Bulk production for knitwear typically runs 15–30 working days after sample approval, depending on quantity and style complexity. Ask what their current lead time is, not their ideal one. Factories with full capacity quote longer lead times and mean it. If you are planning a full range, our custom sweater manufacturing page shows how the pieces fit together.
29. What is your shipping process? Ask about incoterms, packing, carton details and how they handle export documents. If you are importing from China, confirm they have experience with your destination country’s requirements.
30. What happens if the order is late? Ask about their track record and whether they build buffer time into their quoted schedule. A factory that quotes a realistic time and meets it is worth more than one that promises fast and delivers late.
Communication, tech packs and contracts
31. Who is my contact, and what is their English level? You will live with this person for months. Ask who handles your account and how quickly they respond. Time zones matter too: China is 8 hours ahead of London, 13–15 hours ahead of New York.
32. Do you work from tech packs? Send them a sample tech pack and ask for feedback. If they ask smart questions about stitch, gauge and measurements, good. If they say “no problem” to everything, be careful.
33. Will you sign a contract covering price, MOQ, lead time, QC and IP? Your designs, patterns and samples are your property. Confirm the factory agrees in writing not to sell your designs to other buyers, and that your patterns and samples are returned or destroyed after production.
Red flags that should stop you
Some answers end the conversation:
- “We can do everything.” No factory does everything well. Specialization matters in knitwear.
- No clear answer on MOQ structure. They are hiding something, usually higher minimums.
- “Sample is free, just pay shipping.” Fine sometimes. But if they promise free samples of everything without asking about your product, they are not focused on your project.
- No QC process to describe. If QC is “we check everything,” there is no process.
- Rushing you to pay a deposit. A real factory wants your specs and your product details first, not your money.
- Yarn substitution without telling you. If they swap yarn to “save cost” after you approved a spec, that is a breach of trust. Confirm in the contract that yarn changes need written approval.

Frequently asked questions
What is the most important question to ask a knitwear manufacturer?
The most important question is “are you the factory or a trading company?” It determines everything else: control, communication, pricing and QC. After that, ask for the MOQ structure per style, per color and per size, because that is where surprises hide.
How long does a knitwear sample take?
Typically 7–10 working days for a first sample, depending on yarn availability and style complexity. A gauge swatch can be faster. Ask the factory for their current sampling schedule and how many revision rounds are included.
What is a typical knitwear MOQ?
It depends on the factory. Many Chinese knitwear factories in Dalang work with low MOQs, often 100–300 pieces per style, with separate minimums per color and per size. Always ask for the full structure, not a single number.
Should I pay for samples?
Sometimes. Reasonable factories charge for development work when it involves yarn, pattern or labor, and credit the cost against your bulk order. Be suspicious of factories that promise unlimited free samples without asking about your product first.
How do I protect my designs when working with a factory?
Use a written contract that states your designs, patterns and samples are your property, and that the factory will not sell them to other buyers. Keep records of what you sent. Confirm the factory agrees to return or destroy patterns and samples after production.
