From Tech Pack to Bulk Order: What Happens in 30 Days at Our Factory
When buyers ask about lead time, most factories give a single number — "30 days," "45 days" — without explaining what actually happens inside that window. That's understandable from a sales perspective, but it leaves buyers unable to tell a realistic timeline from an optimistic one, or to plan their own launch or restock schedule with any confidence.
This is a walkthrough of the real kidswear manufacturing process at our factory — what genuinely happens between a confirmed tech pack and a finished bulk shipment, week by week, so you know what to expect and what to ask about if a supplier's timeline looks vague.
Before Day 1: What Needs to Be Locked First
The 30-day clock doesn't start when you first reach out — it starts once a few things are confirmed:
- Final tech pack or approved reference sample
- Fabric selection and color confirmation (including any lab dip approval, if it's a custom color)
- Size run and quantity breakdown per size and colorway
- Any special requirements — printing, embroidery, magnetic closures, custom trims
Buyers sometimes lose a week or more here without realizing it, because a "confirmed" tech pack still has an open question about fabric weight or a missing size breakdown. Getting these details locked before production is scheduled is the single biggest lever for keeping the timeline accurate.
Week 1: Sampling and Fabric Sourcing
Once specs are confirmed, two things happen in parallel:
Sample production — Our pattern-making and sampling team produces a physical sample based on the approved tech pack. For most styles, this takes about 5–7 days. You'll receive photos and, if needed, a physical sample shipped for hands-on approval.
Bulk fabric sourcing — At the same time, we begin sourcing and inspecting the fabric quantity needed for the full production run. For standard fabrics (organic cotton, bamboo viscose blends) this usually runs in parallel with sampling; for less common materials or custom-dyed lots, this step can extend the overall timeline, which is worth flagging early if your design calls for anything non-standard.
Week 1–2: Sample Approval
This is the stage most likely to add unplanned time to a project — not because of the factory, but because approval rounds take as long as the buyer's internal review process takes.
A single, clear round of feedback (fit adjustment, color correction, trim swap) typically adds 3–5 days to produce a revised sample. Multiple rounds of open-ended feedback can add weeks. The fastest projects are the ones where the buyer has a clear, specific list of changes rather than a general "make it feel more premium" note — the more specific the feedback, the faster the turnaround.
Week 2–3: Bulk Cutting and Sewing
Once the sample is approved, the order moves into scheduled production. This includes:
- Bulk fabric cutting according to the graded pattern and size run
- Sewing across multiple stations, following the approved sample as the production standard
- In-line quality checks throughout — not just at the end — so issues get caught during assembly, not after a full batch is finished
Week 3–4: Finishing, Inspection, and Packing
The final stage covers everything that turns sewn garments into a shippable order:
- Trimming, pressing, and any final embellishment (printing, embroidery, tag attachment)
- Quality inspection based on AQL 2.5 sampling standards — checking stitching, sizing accuracy, color consistency, and safety details like snap security and label compliance
- Folding, poly-bagging, and cartoning according to your packing specification
- Preparation of compliance documentation — CPC certificates, test reports, and any market-specific paperwork (CPSIA for the US, REACH/EN 71 for the EU/UK)
What Can Extend the Timeline — and What Doesn't Have To
Things that reasonably extend 30 days:
- Custom-dyed or hard-to-source fabric
- Complex construction (multi-panel garments, technical trims like magnetic closures at scale)
- Multiple rounds of sample revision
- Large orders spanning many colorways and sizes simultaneously
Things that shouldn't:
- Standard styles using stock fabric and a single clear round of sample approval
- Reorders of a previously approved style
- Private label orders where only labels/packaging change, not construction
If a supplier's quote adds significant time for a straightforward reorder, it's worth asking specifically why — sometimes it's a legitimate scheduling constraint, and sometimes it's just a default buffer that hasn't been adjusted for your actual order.
Why This Matters Beyond Just Timing
Knowing the real breakdown isn't just useful for planning your launch date. It also tells you where quality control actually happens — and a factory that can walk you through in-line checks during sewing, not just a final inspection, is generally a stronger sign of consistent quality than one that only talks about the end-stage inspection.
Final Thought
A 30-day timeline is only meaningful if you know what's inside it. The more specific a supplier can be about each stage — sampling, fabric sourcing, approval, bulk production, inspection — the more you can trust the number they've given you, and the easier it becomes to plan your own launch, restock, or seasonal drop around it.
