What a pre-shipment inspection is for
A pre-shipment inspection (PSI) takes place when at least 80 percent of the order is packed and the rest is finished on the line. An inspector draws a random sample of cartons, opens them, checks the products against the approved golden sample and the spec sheet, and reports whether the lot passes, fails or is held for a decision. It does not make a bad lot good. It tells you, before the balance payment and before the container is booked, whether the goods match what was agreed.
For tents the inspection has to go further than a visual check, because many failures only show when the tent is pitched: a short pole section, a misplaced clip, a fly that does not reach the stakes, a seam tape that lifts when the fabric is under tension. That is why the pitch test sits at the centre of every tent checklist. The general approach is set out on the quality control page; this note is the working list.
Before the inspector arrives
An inspection is only as good as the reference it checks against. Three documents need to be in the inspector's hands before the visit:
- The spec sheet, with fabric denier and thread count, coating, pole alloy and diameter, floor material, zip sizes, kit contents, label positions and carton marks. See writing a tent spec sheet.
- The golden sample or photos of it, signed and dated, so colour, print, stitching and finish can be compared side by side.
- The inspection plan: sampling level, AQL limits, which tests are run on how many units, and what counts as critical, major and minor. The stated working default on the desk is ISO 2859-1 / ANSI Z1.4 general inspection level II, AQL 2.5 for major defects and 4.0 for minor, confirmed per order.
The checklist by area
| Area | What is checked | How | Typical sample |
|---|---|---|---|
| Quantity and packing | Carton count, carton marks, barcodes, assortment | Count against packing list, scan barcodes | All cartons counted, sample opened |
| Kit contents | Poles, stakes, guy lines, bags, manual, repair parts | Count against kit list | Every sampled unit |
| Pitch test | Tent stands as designed, pole fit, clip and sleeve positions, fly coverage | Full set-up per the manual | A subset of the sample, agreed per order |
| Seams and tape | Stitch density, seam tape adhesion, puckering | Visual, tension check, water spray on seams | Spray test on a subset |
| Zips | Smooth run, slider lock, tape stitching, pull tabs | Open and close each zip several times | Every sampled unit |
| Poles and frame | Section length, shock cord tension, ferrules, hex leg wall, rivets, joints | Measure, assemble, inspect for burrs and cracks | Every sampled unit |
| Fabric | Colour against golden sample, denier and coating per spec, holes, stains | Visual under daylight, compare to sample | Every sampled unit |
| Print and logo | Colour, position, registration, rub fastness on canopies | Compare to approved proof, rub test | Every sampled printed unit |
| Dimensions | Floor footprint, peak height, packed size | Tape measure on pitched tent and bag | Subset of pitched units |
| Labels | Care label, warning labels, tracking labels, country of origin | Check text and position against artwork | Every sampled unit |
| Cartons | Drop resistance, carton strength, inner packing | Drop test to ISTA 1A | One or more cartons per order |
The pitch test is not optional
A tent that has never been pitched has not been inspected. The pitch test catches the failures that a folded tent hides: pole sections cut to the wrong length, a hub that does not lock, a sleeve sewn short, clips on the wrong side, a fly that sits too high to shed water off the inner. On canopies it shows a leg that does not slide, a truss that binds or a top that does not reach the corners. The pitch test procedure describes the sequence in detail, including timing, measurements and what the inspector photographs.
Pitch a share of the sample, not one unit. A single tent that pitches well proves little about a lot of two thousand. The number of units pitched is set in the inspection plan; for complex tents such as air or cabin tents it is usually smaller than the full sample because each pitch takes time, so the plan has to say which defects the pitched subset is looking for.
Water checks: what they can and cannot show
Hydrostatic head is a fabric test to ISO 811, done in a lab on a fabric sample. An inspector at the factory cannot repeat it. What the inspector can do is spray the seams, zip covers and floor corners of a pitched tent and look for water coming through, and peel-check the seam tape at the corners where it tends to lift. The fabric figure is verified from the test report for the fabric lot, confirmed per order. Neither check promises that a finished tent stays dry in every condition; pitch, tension and ventilation matter too. See why tents leak.
Classifying defects
Every finding is classified before the inspection, not after it. A common split:
- Critical: a defect that could injure the user or breaks a legal requirement, such as a missing warning label on a kids play tent, a sharp burr on a canopy leg or a wrong flame-resistance label. Usually zero accepted.
- Major: a defect that stops the product working or would lead to a return: a pole that does not fit, a zip that splits, a seam that leaks under spray, a missing stake bag.
- Minor: a cosmetic defect that does not stop use: a loose thread end, a small stain, a slightly off-centre label.
The defect list is the most useful document in the file. Write each one down with a photo example and the class it belongs to. Tent AQL sampling explains how the counts turn into a pass or fail.
Cartons and drop tests
A tent can pass every product check and still arrive with a bent pole or a split carton. A drop test to ISTA 1A on a packed carton shows whether the inner packing holds the poles and frame in place. Canopy cartons are long and heavy, about 158x27x27 cm for a 10x10 ft commercial reference set, so corners and ends take the impact. Check the carton marks, the gross weight and the carton dimensions against the packing list, because freight is charged on volume.
After the report
- Read the defect summary, not just the pass or fail line.
- For a failed lot, agree the rework: sort and replace, re-sew, re-pack.
- Book a re-inspection on the reworked lot before release.
- Record the findings in the order file so the next order starts with the same checklist and the known weak points.
