The EU's harmonized legal-guarantee notice and conditional GARAN durability label took effect September 27, 2026. If you sell consumer goods into the EU, your listings and storefront need an audit now.

The underlying regulation was adopted a year earlier, in September 2025. What changed is application. eBay says listings missing applicable information may be hidden until corrected.

The Mandatory Notice vs. the GARAN Label

Two separate disclosures are easy to confuse.

The mandatory notice explains existing legal guarantee rights every EU consumer already has. It applies broadly.

The GARAN label describes an additional commercial durability guarantee offered by a producer. It qualifies only when the guarantee costs the consumer nothing extra, covers the entire product, and lasts longer than two years. Offering it is voluntary. Using the label becomes mandatory once the offer qualifies.

A promise covering one component does not meet the whole-product condition. A return window is not a durability guarantee.

Keep separate records for the statutory notice, the producer guarantee, and your own return policy. Collapsing them into one generic warranty field creates errors when the same catalog feeds multiple markets.

What eBay Handles and What You Supply

eBay adds the legal guarantee notice automatically to eligible business listings. Where a qualifying producer guarantee exists, you supply Brand, Model, and Durability Guarantee in whole years from three to 99.

That range is a data entry limit, not an invitation to promise 99 years or to default every listing to three.

Request the actual guarantee statement from suppliers and match it to the specific model. Record producer, duration, covered product, terms, and evidence source. Assign one person to approve changes to those fields.

Then view the live listing as a buyer in the relevant market. Saving an item-specific value does not prove the notice renders correctly across desktop, mobile, and variations.

Why Your Feed Integration Needs Testing

eBay's developer documentation says the new aspect uses existing listing structures with no API schema change required. Category eligibility and localized aspect names still apply.

That is the familiar integration trap: the API accepts the field while your feed generator omits it, mistranslates it, or overwrites it on the next inventory sync.

Test one eligible product with supported guarantee data before any bulk change. Run your normal repricing and stock-sync jobs, then verify the values survived. For products without a qualifying guarantee, leave the field empty rather than populating it to satisfy a completeness score.

Keep an exception queue for ambiguous supplier statements. Escalate those rather than letting automation turn uncertain text into a public commitment.

Auditing Your Own Storefront

For direct sales, use the Commission's official notice and label files. Online displays must appear in color and follow a fixed design.

Customer service needs the same distinction as your product data. A defective product claim, a producer's extended guarantee, and a change-of-mind return should not receive identical scripted responses.

Return handling workflows give you operational structure for separating those cases, though they do not substitute for country-specific legal guidance.

Start with your highest-revenue EU listings and products carrying long warranty claims. Verify supplier evidence, inspect the customer-facing display, and keep dated screenshots. Watch for hidden-listing notices and feed errors after each catalog update.
