Factory Sample Timeline Explained: The 6 Sample Types and How Long Each Takes (2026 Guide)

A factory does not make a sample. It makes six, in sequence, each one answering a different question that bulk production needs answered before the line starts. Most first-time founders ask for "a sample," receive a single garment that looks roughly right, approve it, and discover six weeks later that the color is off, the XL grades wrong, the construction broke down on the bulk line, or there's no signed reference for the AQL inspector to measure against.

This guide walks the six sample types in the order they actually happen. What each one costs, how long each one takes, what you inspect on each, and which ones founders skip — at predictable cost later.

The six sample types, in order

1. Proto sample — does the concept exist?

The proto sample (sometimes "prototype" or "first sample") is the factory's first physical answer to your tech pack. It proves the pattern is drawable, the construction method works, and the material can be sourced. It is not a fit-correct, color-correct, or production-correct garment — it's a feasibility check.

• Cost: $50–150 (sometimes free for repeat customers or large MOQ commitments)
• Time: 2 weeks (1 week for simple knits, 3 weeks for complex constructions)
• Rounds: 1–2 typical
• What you inspect: Does the silhouette match the sketch? Is the construction method what you specified (French seam vs overlock, bound vs blind hem)? Is the fabric weight in the right neighborhood?

What you don't inspect at proto stage: exact fit, exact color, finishing quality. Those come later. If your proto comes back in stock cotton when you specified bamboo jersey, that's a substitution conversation — not a rejection.

2. Fit sample — does the sizing math?

The fit sample is built in your base size (usually M for womenswear, M or L for menswear) to validate measurements, drape, and how the garment sits on a real body. Try it on a real fit model — not a mannequin, not a fit form, a body that matches your spec's measurements within 1cm.

• Cost: $40–100
• Time: 1 week (after proto approval)
• Rounds: 2–3 typical for a new pattern
• What you inspect: Every measurement on your spec sheet, head-to-toe. Sleeve length, body length, shoulder width, hem circumference, armhole depth. Drape under arms, across the chest, at the waist. Stretch recovery if knit.

After fit sample approval, request graded size samples (S/M/L/XL or your full range). The largest and smallest sizes are where grading errors compound — a 1cm error per size becomes 4cm at XL. Catch it in sampling, not in bulk.

3. Lab dip — does the color match?

A lab dip is a small fabric swatch (usually A4-sized) dyed to your Pantone or color reference. It's the proof that the dye-house can hit your color on this fabric, at this GSM, in this finish. It is not a garment — it's a swatch.

• Cost: $30–80 per color per round
• Time: 1 week per round
• Rounds: 2–3 per color is standard; complex colors (deep blacks, fluorescents, neon, certain reds) can need 4–5
• What you inspect: Color match under D65 daylight (or your retail-environment light). Delta-E tolerance — request Delta-E ≤1.5 in writing. Color across the swatch (no streaking). Hand-feel (some dyes stiffen the fabric).

The lab dip is the lowest-cost QC step in your production. A wrong color caught at lab dip costs $30–80 to re-dye. The same color caught after bulk dyeing costs $2,000–5,000 to re-do 200m of fabric. The same color caught after cutting costs the entire run.

Specify D65 light (international daylight standard) for color approval. Some factories will approve under cool white office lighting — colors look different and you'll get a surprise when goods land at your retailer.

4. Pre-production sample (PPS) — does the bulk line build it right?

The pre-production sample (PPS, sometimes "size set sample" or "production sample") is built on the actual production line, using bulk fabric, by the operators who will run the bulk order. It's the most important sample in the sequence — it proves the bulk line can replicate what your senior pattern-maker built in the sample room.

• Cost: $80–150
• Time: 2 weeks (after lab dip + fit are both approved)
• Rounds: 1, ideally — if it fails you've lost 2 weeks
• What you inspect: Everything. Construction quality, stitch density, seam allowance, finishing, label placement, care-label content, color match against approved lab dip, measurements against approved fit sample. Compare side-by-side with your fit sample — they should be near-identical.

The PPS is the reference your AQL inspector will measure bulk against. Sign it off with photo evidence + filled-in measurement sheet + a sealed garment. Without a signed PPS, you have no contractual grounds to reject defects in bulk.

5. Salesman samples — can your buyers see it?

Salesman samples are the multi-piece sets you take to trade shows, send to wholesale buyers, or use for retailer presentations. Usually one set per colorway, in your base size. Some founders skip these entirely (if you're DTC with no wholesale channel) — others need 5–20 sets across multiple SKUs.

• Cost: $50–100 each (often cheaper per piece than PPS because the line is already tooled)
• Time: 2 weeks (can run in parallel with bulk production start)
• Rounds: 1
• What you inspect: Same as PPS — but with extra attention to anything a buyer will hold to the light. Hangtags, packaging, polybag print, the inside of the garment (buyers flip them inside-out).

If you're pre-selling for next season, salesman samples may need to be built before bulk production — which adds 2–3 weeks to the front of your timeline. Factor this in if you're showing at a trade show.

6. Golden sample — the archived reference

The golden sample is the signed-off PPS, formally designated as the master reference for AQL inspection of the bulk. It's sealed, labeled with the PO number + date + signatures, photographed from 8 angles, and archived in two places: at the factory, and in your office.

• Cost: $100–200 (to produce a clean additional copy + ship to you)
• Time: 1 week (after PPS approval)
• Rounds: 1
• What you inspect: Nothing new — but you photograph and document every detail. Stitch count per inch, label placement to the millimeter, color reading on a spectrophotometer if you have one.

The golden sample is what an SGS, Bureau Veritas, QIMA, or Intertek inspector physically holds during DUPRO and PSI inspections. If a bulk garment differs from the golden sample, it's a defect. If you don't have a golden sample, the inspector has nothing to measure against — and your contractual AQL terms become unenforceable.

What it adds up to — a realistic sampling timeline

For a first product (knit apparel, single colorway), the sampling-to-bulk-start sequence looks like this:

Add a second colorway: +3 weeks (lab dip rounds run in parallel for some factories, sequentially for others — ask before you assume).

Add a complex construction (suiting, structured outerwear, denim with wash development): +4–6 weeks, mostly in proto and PPS rounds.

This is why first-time founders are routinely surprised that "the factory said 8 weeks for production" turns into 18 weeks from brief to goods on shelf. The 8 weeks is bulk production. The 10 weeks before it is sampling.

What most founders skip — and what it costs them

The pattern: every skipped sample type is a question that didn't get answered at the cheap stage. The question gets answered anyway — but at the expensive stage. Bulk re-dye is 50–100× more expensive than lab dip re-runs. Bulk rework is 10–30× more expensive than PPS revisions.

How sample fees fit into the factory quote

Sample fees show up in your factory quote either as a line item (preferred — you can see what you're paying for) or rolled into a "development fee" (ask the factory to break it out). Typical sample budget for a first product:

• Simple knit (T-shirt, hoodie): $400–700 total sample fees
• Complex knit (drape-front cardigan, sweater dress): $600–1,000
• Woven blouse/shirt: $700–1,100
• Outerwear/suiting: $1,000–2,000+

Some factories waive sample fees on orders above a certain MOQ threshold (usually 3,000+ units). Most do not. For a first product on a 300–1,000 unit MOQ, plan to pay them.

How Frenzee handles sampling

Every product brief in Frenzee triggers a sampling sequence — proto, fit, lab dip rounds, PPS, golden sample — each with its own approval gate, its own deadline, and its own checkpoint. Sample fees are tracked per round so you can see what you've spent and what's left. Sign-off requires photo evidence + a measurement sheet for fit and PPS gates. Golden samples are logged with PO number + signed date + archive location.

When the bulk production starts, the AQL inspection rules are pre-populated against the signed PPS and golden sample. You don't have to remember to ask SGS or QIMA for a specific reference — it's already in the inspection brief.

The six sample types are not optional. Frenzee just makes sure you do them in order, with the right inspections, and don't discover the gap after the line has already started.
