About This Launch
A browser tool for sellers preparing EU product identifiers ahead of 1 November 2026. Paste up to 25 rows of merchant product ID, non-standardised manufacturer ID and standardised ID (EAN/GTIN), then use Check these rows to flag missing fields, duplicate merchant SKUs and GS1 check digits. Nothing is uploaded, and JavaScript is required.
It is free. The page also promotes a paid $29 EU Customs Product Data Checker for full Shopify CSV exports. Not affiliated with the European Commission or any customs authority. General guidance, not legal, tax or IT advice.
Why I Built This
It was built to help sellers prepare product identifiers before 1 November 2026, with a quick check that runs in the browser and uploads nothing.
