Label claim check sheet

Copy this sheet into your chat with a supplier. Each word on a label gets a question that makes it checkable. For the Kora material, empty rows are marked.

Under research, not yet verified · Basis of the claim row: source summaries that Indonesia has no specific environmental claims rule and that general consumer protection law applies, and EU claims rules that vendor sources say apply from 27 September 2026. We have not read the official text. Ask your legal adviser.

How to use the sheet

  • Copy only the rows that appear on the label or brochure in front of you.
  • Send the questions before you buy swatches.
  • File the answers with the lot number, so your own claim has a basis later.

A simple rule

Write on your product label only what you can prove for that product. If the supplier's evidence covers the starting material only, make your claim just as narrow.

Questions buyers ask

How do I use the label claim check sheet with a supplier?

Copy only the rows for words that appear on the label or brochure in front of you, send the questions before you buy swatches, and file the answers with the lot number so your own claim has a basis later.

What should I ask when a supplier writes bioleather or tested?

For bioleather: what it is made from, how many layers and which tests exist, since the word has no fixed technical limit. For tested: laboratory name, method and edition, date and the lot tested. For the Kora material, nothing is published on either.

What is the simplest rule for writing material claims on my product label?

Write only what you can prove for that product. If a supplier's evidence covers the starting material only, make your own claim just as narrow. Ask a legal adviser about the rules, since the sheet's source summaries were not checked against official texts.
