id identifier Fix “Duplicate listing detected” on TikTok Shop
TikTok detected an item that's very similar to another listing in your catalog or another seller's catalog. Can suppress delivery on both items pending review.
What you see in TikTok Shop:
Duplicate listing detected TikTok flags duplicate listings — variants not grouped under one SPU, same product listed in multiple categories, or resold products matching other sellers' identical listings.
Variant items need shared SPU. Multi-category listing of the same SKU triggers detection. For resold products, brand authorisation typically wins in duplicate-detection scenarios.

Resold products matching other sellers' identical listings
How to fix it
- 1
Identify the suspected duplicates
Seller Center → Products → flagged items.
- 2
If they're variants, group under spu_id
Same product in different sizes/colours should share an spu_id. This consolidates them in TikTok's view.
- 3
If multi-category, pick one canonical category
Don't list the same SKU in multiple categories — it triggers duplicate detection.
- 4
If reselling, verify brand authorisation
TikTok increasingly favours brand-authorised sellers in duplicate-detection scenarios.

Will my listing be removed if duplicate?
