What Is a Pre-Production Sample Actually For?
A pre-production sample is not a preview. It is the reference standard your bulk order gets measured against — the physical document that says what "correct" means. Once you approve it, it is the benchmark for any later dispute.
The bulk order will match the approved sample, not what you meant. Every minute spent checking it costs one unit; every problem missed costs the whole order.
What Five Checks Should You Run, in Order?
1. Fabric weight and hand feel
- Weigh it. Kitchen scales are enough. Compare against the spec: a 38×42cm 12oz tote has a calculable fabric area and weight. A bag noticeably lighter than expected is the most common substitution.
- Check the weave is even, held up to light.
- Confirm the fibre matches what you ordered — cotton, cotton/poly blend, jute.
2. Dimensions
- Measure all three. Width, height, gusset depth. State whether height is measured with or without handles — this is a frequent source of mismatch.
- Measure the handle length and width, and the drop (shoulder clearance).
- Agree a tolerance in writing. Fabric bags are sewn, not moulded; a small tolerance is normal and a stated one prevents argument later.
3. Stitching and construction
- Check stitch density is even and there are no skipped stitches.
- Look for reinforcement where handles meet the body — box stitch or bar tack. This is the single most common failure point on a tote.
- Turn the bag inside out. Seam allowances, overlocking and thread ends tell you more about the workshop than the outside does.
- Check thread colour, and that it is consistent throughout.
4. Logo and print
- Compare colour against a physical Pantone reference, in daylight. Never approve colour from a screen or a phone photo.
- Measure print size and position, including distance from seams and base.
- Check registration on multi-colour prints — no gaps or overlaps between colours.
- Scratch the print firmly with a fingernail. It should not lift.
5. Packing
- Individual polybag, hangtag, care label, barcode — whatever your PO specified.
- Check the label wording and fibre percentages match exactly what you told the factory to print. Compliance obligations sit with you as importer, so this is your check to make, not theirs.
- Confirm carton quantity and dimensions if your warehouse has constraints.
What Two Checks Do Most Buyers Skip?
These take ten minutes and prevent the failures that reach your customer.
- Load test. Fill the bag with the weight it is meant to carry — groceries, books, whatever the use case is — and carry it. Handle attachment failures are the number one complaint on promotional totes, and they show up immediately under load.
- Wash test. Wash the sample the way an end user would. Check for shrinkage, colour bleeding, and print cracking or lifting. A reusable bag that cannot be washed is not reusable in any way that matters.
If a sample fails either test, you have just saved the entire order. If it passes, you have documented that it passes.
How Should You Properly Approve a Sample?
- Approve in writing, referencing the sample. "Sample received 12 March approved" is a usable record; a verbal yes is not.
- Keep a counter-sample. Ask for two identical samples — approve one, keep one sealed and labelled. If bulk quality is disputed, you have the reference.
- Photograph it from all sides, including the inside and the handle attachment, with a ruler in frame.
- List any conditions explicitly. "Approved subject to handle length increased to 65cm" — and confirm the change is understood before production starts.
- Do not approve a sample you have not physically handled. Photos hide weight, hand feel, stitch quality and true colour — the four things most worth checking.
