The “golden age” of duty-free direct shipping is over. With the suspension of De Minimis (Section 321) benefits, sellers shipping individual parcels from overseas are facing a “logistical extinction event” of high tariffs and customs delays. This guide provides the blueprint for the strategic pivot: moving from risky direct-to-consumer air mail to high-performance domestic bulk fulfillment. By importing in bulk and utilizing a US-based 3PL like FBMFulfillment, you protect your margins, bypass the “De Minimis death knell,” and leverage 2-day delivery as a competitive weapon. Adapt your supply chain now before your margins hit zero.
