Apparel Lead Time: Sampling vs Bulk Production Explained
When brands plan a knitwear collection, the most common planning mistake is treating sampling and bulk production as one continuous timeline. They are two distinct phases, each with its own variables. Understanding how long each stage realistically takes helps you set launch dates, book freight, and avoid costly rush fees. This guide breaks down typical lead times for knitted apparel, what influences them, and how to shorten them without cutting corners.
What Is Apparel Lead Time?
Lead time is the total duration from placing a confirmed order to goods leaving the factory. For knitted garments, it generally splits into:
- Sampling lead time — from tech pack submission to approved sample
- Bulk production lead time — from approved sample (and deposit) to finished, packed goods
- Shipping time — separate from factory lead time, and outside the factory’s control
Note that factory lead time refers to production schedules only, not transportation commitments. Always plan shipping separately based on your chosen Incoterm and freight mode.
Sampling: Typical Timeline
Sampling usually moves through several rounds, and each round takes longer than buyers expect:
- Proto sample (first sample) — usually 7–14 days after tech pack is received, depending on fabric availability
- Fitting / revision samples — each round typically adds 5–10 days
- Pre-production (PP) sample — made with bulk fabric and confirmed trims, usually 5–7 days
- Shipping sample — optional, sent from the bulk run before dispatch
A straightforward knitwear style can be approved in 2–3 weeks; a style that needs custom yarn development, dyeing to a specific color standard, or multiple fit corrections may take 4–6 weeks. The biggest driver of sampling time is not factory speed — it is the speed of feedback between buyer and factory.
Bulk Production: Typical Timeline
Once the PP sample is approved and the deposit is received, bulk production of knitted apparel at a mid-size factory generally follows this pattern:
- Fabric knitting and dyeing — 10–15 days if yarn is readily available; longer for specialty or imported yarn
- Cutting and sewing — 10–20 days depending on quantity and style complexity
- Printing / embroidery — often done off-line; adds 3–7 days if outsourced
- Finishing, QC and packing — 3–5 days, including final inspection
For a typical order in the thousands of pieces, a realistic bulk window is 25–45 days. For context, our factory produces around 200,000 knitted garments per month with a 150-person team, which means even 10,000-piece programs move through cutting and sewing without long queue times. Orders starting at the 500-piece MOQ level are usually completed at the faster end of the range.
Factors That Extend Lead Time
- Holidays — Chinese New Year (2–3 weeks) is the biggest single factor; plan orders to ship before it or start after
- Custom fabrics and yarns — melange, slub, or certified yarns (organic cotton, recycled polyester) may require sourcing lead time before knitting even starts
- Slow approvals — each extra sample round adds a full cycle of queue, make, and ship
- Peak season — June–September for knitwear overlaps with other buyers’ pre-holiday production; capacity tightens
- Incomplete tech packs — missing measurements or construction notes trigger questions back and forth before production can start
How to Shorten Your Lead Time
- Submit a complete tech pack: measurements, fabric spec (including GSM), construction details, colors, and trim list
- Consolidate feedback — collect all comments from your team and send one revision note per round
- Choose stock-supported fabrics over fully custom developments when your launch date is fixed
- Approve the PP sample quickly; bulk cannot be scheduled into cutting until PP approval and deposit
- Book freight early during peak season — even a fast factory cannot compensate for a fully booked vessel
A Realistic Planning Example
For a 2,000-piece hoodie program on standard 320 GSM fleece with light embroidery:
- Weeks 1–3: proto sample, one fit correction, PP sample
- Weeks 4–8: bulk production including fabric, sewing, embroidery, QC and packing
- Week 9 onward: shipping (sea freight to US West Coast typically around 2–4 weeks; air freight days)
Total from tech pack to goods in port: roughly 8–12 weeks. Brands that plan to this rhythm rarely pay rush fees.
FAQ
Q: How fast can a sample be made?
A: A proto sample on available fabric is typically ready in about 7–14 days after we receive a complete tech pack.
Q: Does a bigger order take much longer?
A: Not proportionally. Knitting and dyeing scale well; the sewing line schedule is the main variable. A 10,000-piece order may only add a few days over a 2,000-piece order of the same style.
Q: Can lead time be quoted before I have a tech pack?
A: We can give an indicative range, but a firm production schedule requires the approved sample, confirmed quantities, and deposit.
Q: How quickly do you respond to inquiries?
A: Quotations are typically returned within 5 working days (UTC+8) of receiving full order details.
