Product Sampling Checklist: What to Check

A practical checklist for evaluating supplier samples from China — materials, finish, dimensions, function and documentation.

Why samples decide everything

A sample is the supplier's promise made physical. Approving a sample without checking it against your brief is how quality problems get imported.

What to check

  • Materials: match your specification, not just your description
  • Finish: surfaces, seams, printing, and plating — where corners get cut
  • Dimensions: measure, don't eyeball — tolerance matters
  • Function: assemble and use it the way your customer will
  • Packaging: what the customer receives, and what survives shipping
  • Documentation: test reports, material certificates, and the sample's production date

Before you approve

  • Compare the sample against the written brief, not your memory of it
  • Confirm the production version will match the approved sample — in writing
  • Ask whether the sample was handmade or from the production line (handmade samples can hide real production quality)
An approved sample is a contract. Approve it deliberately, in writing, against a checklist.
