Your product title is longer than TikTok Shop's character cap. Titles must be concise and fit within the platform's display constraints.
TikTok Shop enforces a tight title length (typically 60 characters for US, 34 in some markets) so product names render cleanly in mobile feed cards. Sellers porting Amazon-style titles stuffed with keywords, sizes, and color variants commonly overflow this limit. The system truncates and then rejects rather than display a malformed title.
