How to Prepare for a Pre-Shipment Inspection: What to Send Your Inspector / QC Company

Most disappointing inspections do not fail at the factory. They fail at the desk of the importer who booked them — because the inspector was never told what "good" looks like. An inspector is not a mind reader. They verify your goods against a standard, and if you do not supply that standard, they fall back on generic defaults and their own judgement. You then receive a report that technically "passed" but never checked the three things that actually matter to your customer.

The single highest-leverage thing you can do to get value from a pre-shipment inspection is to brief it properly. This guide walks through exactly what to send your inspector or QC company — and when to send it — so the inspection measures your product against your requirements.

Why the brief matters more than the inspection

Think of the inspector as an independent referee. A referee needs the rules of the game before kick-off. Give a clear rulebook — specifications, an approved sample, tolerances, acceptance criteria — and the referee can make objective calls that both you and the supplier will respect. Give nothing, and every judgement becomes a matter of opinion, which is exactly where buyer-supplier disputes come from.

A well-prepared brief does three things: it tells the inspector what to check, it defines the line between "acceptable" and "defective," and it gives you an objective basis to hold the supplier accountable — this order, and the next one.

The 7 things to send your inspector

Here is the core package. You do not need all of it for every product, but the more you provide, the more precise and defensible the result.

1. Purchase order & quantities

Send the PO so the inspector can confirm they are looking at the correct product and reconcile quantities. If your order has an assortment — say 30% small, 40% medium, 30% large, split across three colours — spell it out. Quantity and mix errors are among the most common findings, and they are only catchable if the inspector knows the target.

2. Specification, tech pack or drawings

This is the objective standard. For garments it is the tech pack; for mechanical parts it is the engineering drawing with tolerances; for electronics it is the spec sheet and safety requirements. Whatever form it takes, it turns "does this look right?" into "does this conform?" If your specification is thin, that is the first thing to fix — an inspector cannot enforce a requirement that was never written down.

3. The approved (golden) sample

A golden sample is a production unit you have inspected and signed off as the reference. The inspector compares the batch against it for colour, materials, construction and finish. Ideally the factory holds a sealed, dual-signed sample and you hold a matching one. Without a golden sample, "matches the approved standard" is subjective — and subjective calls are the ones that turn into arguments after the goods land.

4. Measurement sheet and tolerances

List every point of measurement, its target value, and the tolerance the inspector should apply (for example, chest width 52 cm, tolerance +/- 1 cm). Tolerances matter enormously: a part that is "1 mm off" is a pass or a fail depending entirely on whether you specified +/- 0.5 mm or +/- 2 mm. Do not leave the inspector to guess — a missing tolerance is a missing decision.

5. Packaging and labelling requirements

Packaging is where perfect products become unsellable. Give the inspector the retail artwork, the barcode type and placement, the shipping-mark format, and any care or regulatory labels required for the destination market. For Amazon sellers this includes FNSKU labels, poly-bag suffocation warnings and carton box-ID rules — see our Amazon FBA inspection checklist. A barcode that does not scan can hold up an entire shipment.

6. AQL levels and inspection level

Tell the inspector your Acceptable Quality Limits — commonly 0 for critical, 2.5 for major and 4.0 for minor — and the inspection level (General Level II is the usual default). These decide how large a sample is drawn and how many defects are allowed before the lot fails. If AQL is new to you, our AQL tables guide explains it, and the free AQL sample size calculator turns your order quantity and AQL into the exact sample size and accept/reject numbers in seconds.

7. Special tests and acceptance criteria

Finally, list any tests beyond the visual: function tests, a carton drop test, a pull test on small parts, a colour-fastness rub test, needle detection for garments, a hi-pot test for electronics. For each one, define the pass/fail criterion. "Test the zipper" is vague; "operate each zipper through 30 open-close cycles with no breakage or detachment" is something an inspector can objectively verify. For how these map to defect severity, see critical, major and minor defects explained.

Who confirms the goods are ready — and when

Here is a practical reality that trips up first-time importers: you usually will not know the exact day production finishes. Factories run late, catch up, or repack, and the completion date moves. So timing is not something you pin down alone from your desk weeks in advance.

In practice, the factory notifies the inspection company when the goods are ready, and the QC company stays in touch with the factory to confirm that production has reached the right stage — typically 80% or more produced and packed — before an inspector is sent. Your role is to make that coordination possible: give your inspection provider the factory's contact person, book with a few days' lead time, and authorise them to arrange the exact date directly with the factory. A good inspection company will chase the factory for a firm ready-date and schedule the visit accordingly — so you are not left guessing, and the inspector does not turn up to half-finished goods.

Three mistakes that ruin an inspection before it starts

Make the brief reusable: use a template

Most of this brief is the same from order to order. The efficient approach is to build a structured inspection checklist once, per product category, and reuse it — updating only the specifics each time. That way nothing is forgotten and your inspector receives a consistent, complete package every shipment.

We publish free, editable pre-shipment inspection report templates by product category — apparel, electronics, footwear, furniture, homeware, toys, mechanical parts and Amazon FBA. Each lays out the checkpoints, sampling structure and acceptance fields so you can hand your inspector a professional brief in minutes. And our AI report tools (launching soon) go further — building a tailored template directly from your spec and tech-pack, and reviewing completed reports against the AQL.

A quick timeline

Preparation is unglamorous, but it is the difference between an inspection that protects you and one that simply happened. Send a clear brief, and the report becomes a genuine second opinion you can act on — approve, reject or negotiate — with confidence.
