How Long Does Custom Knitwear Production Take?

Short answer: Plan for a minimum of 55–65 days from an approved tech pack to goods on a boat, and closer to 90 if you include two sample rounds. Sampling alone is 7–10 working days per round; bulk production is 35–50 days; finishing and QA add 5–7; ocean freight to a US or EU port is another 28–40. Anything a factory quotes as “30 days all in” is either a stock programme or a lie you will discover at the port.

Most buyers think of lead time as one number a factory gives them. It isn’t. It is four numbers that stack, and the factory only controls one of them well. The rest are physics, holidays, and customs — none of which a supplier’s salesperson can actually bend.

The Real Timeline, Stage by Stage

Sampling Is Where Projects Die

Buyers lose more calendar time in sampling than in production, and almost none of it is the factory’s fault. The usual killers: a tech pack that arrives without a graded size spec, a colourway approved late, a PP sample sent back for a change that should have been caught at proto. Each round trip by courier is 4–6 days each way, and most buyers underestimate how many they will need. My blunt advice: spend the money on a clean tech pack and a real proto round, because every day you save in sampling is a day you keep before the Chinese New Year cliff.

The Chinese New Year Cliff

This is the single biggest lead-time risk in the knitwear calendar and Western buyers consistently forget it. The holiday shuts knitting, dyeing and finishing across the Yangtze Delta for two to three weeks, and everything queued behind it slips by the same amount. A bulk order confirmed in early January ships; the identical order confirmed in mid-February is three weeks late before it starts. If your goods need to land before March, your bulk order should be confirmed before the holiday, not after.

Peak Season Tax

August through October is when everyone in the Northern Hemisphere wants the same machines. Capacity tightens, overtime gets priced in, and a 40-day programme quietly becomes 48–55. If your delivery window is autumn/winter, confirm by May or June. Confirming in August and expecting a 40-day turn is how brands miss their own launch dates.

How to Compress the Timeline Honestly

Conclusion

Lead time is not a number a factory gives you; it is a chain of four numbers, and three of them are outside the factory’s control. The buyers who ship on time are the ones who start sampling early, book yarn before the holiday, and treat the production calendar as part of the design brief rather than an afterthought.

Key Takeaways for Buyers

How We Schedule Production

We map the calendar before we quote, because a sweater quoted in August with a September ship date is a different job from the same sweater quoted in February. We give you a dated timeline — sampling, bulk, finishing, vessel — and we tell you plainly when a date is unrealistic. Send us your tech pack and target delivery month and you will get a schedule you can build a launch around, not a number you have to negotiate.
