A private label denim program is five steps. Every delay and dispute in the industry traces back to one of them being skipped or rushed. Here is the sequence with honest timelines.
Step 1 · Tech Pack (Week 1)
Your tech pack is the contract: measurements by size, fabric spec (weight, composition, dye), construction details, trims, wash standard, labels. A complete tech pack converts a two-month email spiral into a three-week program. If you cannot produce one yet, ask the mill for their template — good mills keep them.
Step 2 · Sampling (Weeks 2–4)
Swatch → proto → fit → sealed PP. The sealed sample is the reference bulk is graded against. Never skip the seal — "we trust you" is how reorders stop matching. Full sampling timeline here.
Step 3 · Bulk Production (Weeks 5–9)
Fabric weaving and dyeing, cutting, sewing, washing, finishing. For a 50–500 pair run at a vertical mill this is 35–45 days. Ask for mid-production photos — a factory with nothing to hide responds in hours.
Step 4 · QC & Packing (Weeks 9–10)
- Measurement audit against the sealed sample, by size.
- Wash/color consistency check under D65 light.
- Hardware and label placement verification.
- Packing to your retail spec — poly, hanger, carton marks.
Step 5 · Logistics (Weeks 10–13)
Sea freight is the default; air freight is for launches that cannot slip. Incoterms decide who owns each leg — FOB is the cleanest for comparing factories. Confirm HS code and duty for your market before booking, not after.
First program: 90 days tech pack to door. Repeat orders of the same style: 45–60 days, because Steps 1 and 2 collapse into a confirmation round.
Where Programs Fail
- Skipping the sealed PP sample (disputes with no referee).
- Changing spec mid-bulk (restarts fabric, resets the clock).
- No mid-production checkpoint (surprises arrive in cartons).
