What changed: Starting November 12, 2026 (PT), shops found charging excessive shipping fees or using inaccurate or manipulated product weights will have the order-creation estimate kept at or above the estimate at shipment, so lowering weight before Ready to Ship won't cut the fee; it covers TikTok Shipping Standard Delivery, CBT (Collection by TikTok) and Express orders.
When: Deadline: Nov 12, 2026.
Who is affected: TikTok Shop sellers (Best sellers).
What to do: Audit package weights (product plus packaging, labels and bundled items) and keep shipping fees separate from product price before Nov 12; flagged shops get a violation notice in Seller Center and can appeal through Seller Support.
