Flag textile trade names
Flag Lycra and Tencel on fibre fields — do not treat trade names as Annex I composition
Direct answer. Shopify product fields accept any fibre string you type, including trade names like Lycra or Tencel, and Admin does not flag them against the EU Annex I catalogue. FibreLedger Textile Labels flags trade names like Lycra or Tencel that are not lawful fibre names so you can replace them with Annex I names before the product page ships.
FibreLedger Textile Labels (Shopify App Store) validates every fibre against the official Annex I catalogue (EN, DE, FR), flags trade names like Lycra or Tencel that are not lawful fibre names, and supports French places of manufacture and environmental-impact fields. This page is the trade-name flagging slice — not the full Annex I composition overview, language-of-market, French places, environmental-impact fields, or EPR records. This page is not legal advice.

Free check first: Textile fibre composition checker runs in your browser and sends nothing. Check fibre names against the EU Annex I list and that the blend adds up to 100%.
Trade-name flags are not the same job as writing the composition line
The composition overview explains why Annex I names belong on the label. This page is the scan-and-flag job: catch Lycra, Tencel, and similar trade names in fibre fields before they reach the storefront.
How to flag trade names like Lycra or Tencel
- Run validation on product fibre composition fields.
- Review flags for trade names that are not Annex I fibre names.
- Replace flagged trade names with the lawful Annex I names you intend to show.
- Confirm the live product page no longer shows the trade name on the composition line.
Not the same as Annex I overview, language-of-market, French places, impact fields, or EPR
- Annex I overview — EU textile fibre labels need Annex I names, not trade names.
- Language of market — composition language on Shopify.
- French places — France places of manufacture.
- Impact fields — environmental-impact information.
- EPR records — EPR registration and audit records.
Install FibreLedger → flag trade names → confirm product page
What this page is not
- Not legal advice or a full textile-label compliance certificate.
- Not a substitute for the Annex I overview sibling — use both: flag trade names here, keep composition rules there.
