Opening only one bag near the container door may not represent an entire shipment. A sampling plan should define which lot is sampled, from how many locations, by what method and for what purpose.

Define the lot first

The sampling plan should follow lot structure. If a container contains multiple production lots, separate evaluation may be needed.

Use distributed selection

Packages should not all come from the easiest pallet or container-door area. Selection across different shipment locations can provide better representation.

When can composite sampling help?

Combining multiple increments can help evaluate average properties, but it can also hide a localized problem. The approach should match the decision being made.

Separate laboratory and retain samples

In addition to the test sample, a sealed reference or retain sample can support retesting or dispute investigation.

Maintain chain-of-custody records

Record who sampled, when, the lot, pallet/package reference, sample quantity, seal and transfer to the laboratory.
