What is changing

Decathlon is making the following changes in product attributes: 

• The condition of the product becomes mandatory, to distinguish new and second-hand products.
• New GPSR attributes are available to provide manufacturer information (legal requirement).
• Language attributes are simplified for Belgium with the removal of nl_BE and fr_BE attributes, to keep only the fr_FR and nl_NL attributes.
• The sizes of the Apparel and Footwear categories are simplified, with fewer attributes and fewer valid values.
• Specific "Best for Sale" attributes become mandatory for certain categories (running shoes, treadmill, trampoline, etc.) to improve product visibility. The list of valid values is simplified for some attributes.

The detailed list of changes is available here 

Decathlon allows merchants several weeks to adapt to the changes before the attributes become mandatory. 
All merchants must complete the required attributes by week 24 of 2025 (09-13 June).

What you have to do in Lengow

Decathlon is planning the completion campaign from week 21 (19-23 May) to week 24 (09-13 June) of 2025. 

The new attributes and values are already available in Lengow, but are not marked as mandatory yet. 
The outdated ones will be removed after the completion period.

• "GPSR - Warnings" (available soon) optional but recommended: List of values you can choose from if your product is matching one of these warnings.
