TikTok Shop enhances shipping options through the Postal Service for its sellers.

Starting January, TikTok Shop will mandate that all U.S. Postal Service shipping labels be purchased and printed through TikTok Shipping, affecting sellers' fulfillment processes. While sellers can still engage directly with other carriers, any USPS labels from external sources will be rejected, consolidating TikTok's control over shipping. This change may complicate logistics for some e-commerce providers, as they evaluate whether to adapt to TikTok's system or opt for other carriers, with an emphasis on cost implications for shipping small and lightweight products.
