A typical custom knitwear order takes 7–10 working days for sampling and 15–30 working days for bulk production. The full process, from your first tech pack to finished goods, usually runs 8–12 weeks once you count yarn confirmation, sample approvals, finishing, and shipping.
Most of that time isn’t spent knitting. It’s spent on decisions — yarn, gauge, colors, trims — and on the finishing steps that make a sweater actually sellable.
If you’re a brand planning a collection, the practical takeaway is simple: work backwards from your launch date, lock the spec at sampling, and don’t treat the quoted lead time as the whole timeline.
The short answer: sampling, bulk, and the gap between them
Here’s what a realistic custom knitwear timeline looks like at a mid-size Chinese knitwear factory:
| Stage | Typical time | What happens in this stage |
|---|---|---|
| — | — | — |
| Sampling | 7–10 working days | Yarn review, first sample, measurement check, fitting notes |
| Bulk production | 15–30 working days | Yarn ordering, knitting, linking, finishing, QC, packing |
| Full project, kickoff to shipment | 8–12 weeks | Everything above, plus your approval time and transit |
At Lewen Garment, a simple style samples in 7–10 working days from confirmed spec. Complex styles — heavy cables, intarsia, special yarns — take longer, and the timeline is confirmed before sampling starts.
Two things to notice.
First, sampling and bulk are separate commitments. You don’t get one combined timer. You get a sample, you approve it (or send it back with changes), and only then does bulk production start.
Second, the 8–12 week number is a planning figure, not a factory promise. It’s what a realistic calendar looks like when you include the back-and-forth that every custom project has. A straight reorder of an existing style with stock yarn will be faster. A new style with custom-spun yarn, a jacquard pattern, and three colorways will be slower.
What actually drives production time
Not all knitwear takes the same time. These factors move the number more than anything else:
Style complexity. A plain 12-gauge pullover is fast. A cable-knit style needs pattern programming. A jacquard needs a pattern grid and multi-color feeding. An intarsia style means yarn changes mid-row for every color block. Each one adds setup and machine time.
Yarn status. This is the biggest hidden variable. If the yarn is a stock item the factory already carries, knitting can start quickly. If you want a specific fiber blend, custom-spun yarn, or dyed-to-order colors, the yarn order itself takes weeks before a single stitch is knitted. Ask about yarn availability before you ask about lead time.
Gauge. Different gauges use different machine ranges. A factory’s 7-gauge machines and 12-gauge machines are separate pools. If your style needs a gauge that’s fully booked, you wait for machine capacity, not for knitting speed.
Color count. Every additional colorway is a separate dye lot, separate yarn stock, and separate production run. Four colors isn’t four times the work — but it’s not one times the work either.
Finishing. Fully-fashioned knitwear goes through washing, drying, steaming, and pressing. Treatments like anti-pilling, softening, or shrink-resist finishing add steps. If you’ve seen a sweater that looked “factory-fresh,” finishing is why — and it takes time.
Trims and details. Buttons, zippers, embroidery, and prints are usually sourced separately. A custom button with your logo can take longer than the garment itself. Decide trims early.
QC. Final inspection is not optional. A factory that skips it will ship you the savings in the form of defects. Good factories schedule inspection as a real step, not a hope.
Sampling: the stage people underestimate
The 7–10 working day sample window is the factory’s production time for the sample. It assumes the spec is clear and the yarn is available. It does not include:
- your response time when the sample arrives
- revision rounds (each round is another 7–10 working days)
- yarn changes made after the first sample
Realistically, most brands go through two to three sample rounds on a new style. First sample checks construction and measurements. Second sample fixes the issues. Third sample happens when the second round introduced a new problem or when the buyer changes something.
You can compress this. Send a proper tech pack — measurements, stitch details, yarn spec, reference photos. Or send a reference garment. The less the factory has to guess, the fewer rounds you’ll need.
One more thing: sampling and bulk are not always the same machine or the same worker. A factory may knit your sample in its development room, then move production to the main floor. Confirm the sample was made with the same gauge and yarn as the bulk order will use.

Bulk production: 15–30 working days, broken down
A bulk knitwear order moves through these stages:
- Yarn ordering and dyeing — if the yarn isn’t stock. This step happens before anything else and often runs in parallel with your final sample approval.
- Knitting — the fabric or fully-fashioned panels are knitted on the machines.
- Linking and sewing — panels are joined. Fully-fashioned styles are linked stitch-to-stitch; cut-and-sew styles are cut and sewn. Linking is skilled hand work and is usually the capacity bottleneck.
- Finishing — washing, drying, steaming, pressing, and any special treatments.
- Final inspection and packing — measurement checks, defect checks, folding, polybagging, and carton packing.
The 15–30 working day range covers all five steps for a standard order. Where you land in that range depends on the factors above: yarn, complexity, color count, and how full the factory’s schedule is.

Why quoted lead times differ between factories
Every factory will quote you a lead time. They won’t all be honest in the same way.
Capacity utilization. A factory running at 90% capacity quotes longer times because it’s true. A factory running at 40% quotes shorter times because it wants the order. Neither is lying; both are telling you about their schedule.
Production line structure. Some factories run dedicated lines per customer. Others mix styles through shared machine pools. Dedicated lines are more predictable; shared pools are cheaper but slower during peaks.
Seasonality. Knitwear has a hard seasonal curve. From around April to September, factories are filling autumn/winter orders. This is when lead times stretch. In the off-season, the same factory can turn orders around noticeably faster.
The sales quote vs. the production reality. A salesperson quoting 20 days may not know the knitting floor is booked out for three weeks. Ask for a written schedule with dates, and ask what happens if the date slips. A factory that commits in writing is a factory that has thought about it.
How to plan your production calendar
Work backwards from your on-sale date:
- On-sale date — when the collection hits your store.
- Minus transit — sea freight from South China to the US or Europe is typically 3–5 weeks; air freight is days but costs multiples more.
- Minus bulk production — 15–30 working days, plus buffer for delays.
- Minus sampling and approvals — 3–6 weeks for a new style with revisions.
- Minus initial development — a week or two for yarn and gauge discussion before the sample order.
For an autumn/winter knitwear line, that math usually puts your bulk order somewhere around June–July for a September–October launch, and your sampling a month or two before that. If you’re sourcing closer to the season, expect to pay for air freight or to accept fewer style options.
Two calendar realities worth planning around:
Chinese New Year. Factories in China typically close for 1–2 weeks and take another week or two to ramp back up. Orders placed in January often land in March. If your launch can’t slip, don’t schedule a new development project in that window.
If you’re still comparing factories, how to choose a reliable knitwear manufacturer in China covers what to check when a salesperson quotes you a lead time.
Your own approval speed. Every day you hold a sample is a day of factory idle time you’re paying for later. Set internal deadlines for sample review. The fastest factory in China can’t help you if your team sits on a sample for two weeks.
Common mistakes that add weeks
- Starting bulk before sample approval. The factory follows your written instruction. If you say “go” on a sample with pending changes, you own the result.
- Changing the spec mid-production. Yarn, gauge, or measurement changes during bulk don’t just add time — they usually mean scrapped panels and a restart.
- Leaving trims until the end. Custom buttons and embroidered labels have their own lead times. Order them when you order the yarn, not when the garments are finished.
- Describing colors in words. “A warm cream” means nothing to a dyer. Use Pantone references or physical yarn cards. Color approval is one of the slowest loops in knitwear; make it objective.
- Ordering at peak without a contract date. A verbal “we need it by October” in August is a hope, not a schedule. Get a written production schedule with milestone dates.
FAQ
How long does knitwear sampling take?
Typically 7–10 working days at Lewen Garment, from confirmed spec to finished sample. Each revision round adds another 7–10 working days. Providing a complete tech pack or reference garment reduces the number of rounds.
How long does bulk knitwear production take?
Typically 15–30 working days, depending on yarn availability, style complexity, color count, and the factory’s schedule. Stock yarn and a simple style land at the short end; custom-spun yarn or jacquard patterns land at the long end.
Why is my knitwear order taking longer than the quoted lead time?
The usual causes: yarn wasn’t in stock, a sample revision wasn’t counted, trims arrived late, or the factory was fuller than the sales quote suggested. A written schedule with dates — and your own fast sample approvals — prevents most of this.
Does a higher MOQ make production faster?
Not really. MOQ affects how long the knitting and finishing stages run, but the fixed costs — yarn ordering, machine setup, pattern programming, sample rounds — take the same time regardless of quantity. A bigger order uses capacity longer; it doesn’t move the start date earlier. For how low MOQs work in practice, see low MOQ knitwear sourcing.
When should I start production for an autumn/winter knitwear line?
For a September–October launch, plan sampling around March–April and bulk production around June–July. That leaves room for sample revisions, sea freight, and the usual small delays. If you’re later than that, expect air freight costs or a compressed style count.
