UPS's Happy Returns unit is bringing its label-free returns option to TikTok Shop, integrating itself in a popular e-commerce platform.

With the offering, shoppers will be able to return TikTok Shop orders to one of Happy Returns' nearly 10,000 locations without a box or printed label before the items are transported through the UPS network. The offering marks TikTok shop's only box-free, label-free returns option, Happy Returns said Tuesday.

Happy Returns said the move brings its service into one of the fastest-growing commerce ecosystems where people discover products and brands.

"Commerce today spans social platforms, marketplaces and owned e-commerce channels--retailers need logistics solutions that can connect all of it," Happy Returns' Chief Executive David Sobie said.

The service is now available for participating retailers across TikTok Shop, whether the merchant handles its own fulfillment or has orders fulfilled by the social-media platform, Happy Returns said.
