TikTok Shop is tightening its control over fulfillment by changing how sellers access USPS shipping. The update forces sellers to adjust workflows or absorb higher shipping costs ahead of the new year. Here's what you need to know...
-
Starting in January, TikTok Shop will require all USPS shipping labels to be purchased and printed through TikTok Shipping.
-
USPS labels generated through platforms like Shopify, ShipStation, or Postal Service accounts will no longer be accepted, increasing TikTok Shop’s control over shipping on its marketplace.
-
TikTok Shipping offers label creation for USPS, UPS, and FedEx, but logistics firm Tactical Logistics Solutions expects many sellers to adopt hybrid strategies using USPS through TikTok when it makes sense and shifting more volume to UPS or FedEx when control and consistency are most important.
-
Axion, a third-party logistics provider, said it will avoid TikTok Shop labels due to margin pressure and operational complexity, and will choose to ship orders via UPS, FedEx, or Amazon Shipping.
-
Small and lightweight product sellers are most affected, as USPS is often the only cost-effective option, meaning higher shipping costs may be passed on to sellers or consumers.
