TikTok Shop US Logistics: USPS Labels, MCF & Tracking

TikTok Shop U.S. has updated its logistics policy, announcing that, starting October 27, 2025 (Pacific Time), certain fulfillment rules for cross-border, seller-fulfilled (POP) merchants will be adjusted. This TikTok Shop US logistics policy clarifies label and carrier use, with particular emphasis on the USPS shipping label requirement.

Under the new policy, merchants who ship via USPS must use the official labels provided by TikTok Shipping. If you choose other third-party logistics providers (non-USPS), the platform recommends planning capacity in advance to ensure on-time fulfillment.

For execution, the platform specifies the following:

• When using UPS Mail Innovations (UPS MI), DHL eCommerce, or FedEx SmartPost, only the corresponding carrier’s tracking numbers are supported. USPS tracking numbers may not be used for these services; otherwise, system validation will fail.
• Orders fulfilled through Amazon FBA Multi-Channel Fulfillment (MCF) are prohibited from using USPS labels.

In addition, TikTok Shop is encouraging merchants to adopt its official logistics solutions such as Fulfilled by TikTok (FBT). Sellers choosing these channels must maintain accurate inventory data and complete fulfillment through designated ERP systems or the Seller Center.

The platform advises affected merchants to complete logistics configuration updates before October 27 and promptly coordinate with overseas warehouse partners to adjust delivery methods. This helps prevent shipment failures or hit rates on fulfillment performance caused by incorrect tracking numbers or carrier selection.

Industry observers note the adjustments may be related to the September joint effort by TikTok and USPS to crack down on “postage-due” shipments and “fraudulent labels,” which led to delays for some cross-border parcels.

According to TikTok Shop, the update is intended to safeguard the consumer delivery experience and improve overall fulfillment efficiency.

For cross-border sellers, the practical steps are clear: align with platform rules, audit existing logistics channels, evaluate the cost-to-service trade-offs of official programs, and communicate early with overseas warehouses to ensure compliant, uninterrupted shipping. References to Amazon FBA MCF should also be reviewed to confirm that USPS shipping label restrictions are observed across workflows.

As this TikTok Shop US logistics policy takes effect, merchants should validate label sources, verify carrier mappings (UPS MI/DHL eCommerce/FedEx SmartPost), and document any Amazon FBA MCF constraints in their SOPs.
