category_id categorisation Fix “Missing category mapping” on TikTok Shop
TikTok Shop uses its own product category taxonomy (separate from Google's). Items without a mapped category_id are rejected because TikTok can't route them to the right shopping surfaces.
What you see in TikTok Shop:
Missing category mapping TikTok uses its own category taxonomy distinct from Google's. Items without TikTok-specific category mapping can't be routed to appropriate shopping surfaces and get rejected.
The fix is mapping each item to TikTok's category_id (different from google_product_category). For multi-channel catalogs, maintain both — Google's GPC for Google/Pinterest/Meta, TikTok's category_id for TikTok specifically.
Top causes
- 1
Feed uses google_product_category but no TikTok category_id
- 2
category_id maps to a TikTok category that no longer exists (taxonomy updates)
- 3
Auto-mapping based on title keyword matched the wrong TikTok category
How to fix it
- 1
Get TikTok's current category taxonomy
TikTok Seller Center → Categories → download the latest taxonomy CSV.
- 2
Map each product to a TikTok category_id
Either manually for small catalogues, or via a mapping table that takes google_product_category as input and outputs the closest TikTok category_id.
- 3
Populate the category_id field
Add the category_id to each row in your TikTok feed. Don't rely on auto-mapping unless your titles are extremely consistent.
- 4
Re-submit and verify
Submit through Seller Center. Items typically clear within 2-4 hours after re-submission.

Invalid availability
TikTok Shop's availability field is stricter than Meta's or Google's. It accepts specific values ('in stock', 'out of stock', 'preorder') and rejects anything else. Items with invalid availability are rejected from the catalog.
Read moreImage too small for TikTok
TikTok Shop's minimum image resolution is 600×600 — higher than Google's or Meta's. Items with smaller images fail validation. TikTok also prefers vertical aspect ratios for video-first placements; a square image will work but won't perform as well.

FAQ
Can I use google_product_category instead?
TikTok prefers its own category_id but accepts google_product_category as fallback for items without a TikTok mapping. Include both for best coverage.
How often does TikTok update its taxonomy?
Typically twice a year. Updates can deprecate old category_ids, which is why feeds drift into errors over time. A quarterly remap is reasonable maintenance.
