What happened?
TikTok Shop’s U.S.-Mexico logistics policy states that non-FBT cross-border sellers will be subject to the new shipping-charge arrangements from March 12, 2026, while FBT sellers will be subject to the corresponding rules from June 29, 2026. Shipping charges are generally calculated using the higher of actual weight and dimensional weight. For some non-FBT orders, the weight verified by the carrier may also be used. The platform will handle or prepay relevant import taxes and adjust the final amount charged to sellers in settlement. Non-FBT parcels are also subject to size and weight limits: the maximum listed dimensions are 38 × 48 × 58 cm and the maximum weight is 22 kg. The policy is particularly relevant to lightweight bulky goods, home products, soft-packaged products and large, low-priced items. Sellers should remeasure outer cartons, optimize packaging and avoid discrepancies between system data and the carrier’s actual measurements.
What does this mean for cross-border sellers?
The TikTok Shop U.S.-Mexico program charges based on the higher of actual and dimensional weight, which may raise logistics costs for lightweight bulky goods, home products and large low-priced items. Non-FBT parcels must also stay within 38 × 48 × 58 cm and 22 kg, so packaging and system data need to be rechecked.
What should sellers do now?
- 1This week, separate non-FBT and FBT products shipped from the United States to Mexico, create a checklist under the rules effective March 12, 2026 and June 29, 2026, and identify the applicable stores, products and effective dates.Dimensional weight

- 3Redesign packaging for lightweight bulky goods, home products, soft-packaged products and large low-priced listings; prepare a before-and-after size and weight comparison, and sample-check that carrier-verified weights match system data.
