A pre-production sample (PP sample) is the last sample a factory makes before cutting bulk fabric — produced on the actual production line, in the actual fabric and trims, with all labels and packaging. Approving the PP sample is the green light for mass production, so it deserves your full attention.
Where PP Samples Fit in the Process
The typical sample sequence runs: proto sample (first look at the design) → fit sample (fit corrections in muslin or actual fabric) → salesman samples (for showing buyers) → pre-production sample (the exact bulk standard). Some brands add a TOP (top of production) sample pulled from the first bulk units as a final confirmation.
What to Check on a PP Sample
Measure every spec point against your tech pack tolerances. Check fabric hand, color, and shrinkage against approved swatches; test zippers, snaps, and buttons for function; verify label placement and legal content; inspect stitching density and seam finishes. Photograph and document every deviation — then decide: approve, approve with comments, or reject and re-sample.
Who Pays and How Long It Takes
Sampling fees typically run $50–$300 per style, often credited against the bulk order. Expect 1–3 weeks per sample round depending on the factory's workload. Never skip the PP sample to save time — a rejected bulk shipment costs orders of magnitude more than one more sample round.
FAQs
- What is the difference between a PP sample and a fit sample?
- A fit sample checks measurements and fit, often in substitute fabric. A PP sample is made in actual bulk fabric and trims on the production line — it represents exactly what bulk will look like.
- How many PP sample rounds are normal?
- One to two rounds is typical. More than three usually signals a tech pack problem or a factory capability problem.
- Can I approve a PP sample by photo?
- Photos help for quick checks, but physical approval is the industry standard for anything beyond simple styles — hand feel, true color, and construction quality don't photograph reliably.
- What happens after PP approval?
- The factory cuts bulk fabric. Any change after this point usually triggers re-sampling charges and delays, so the PP approval is contractually significant.
