"U.S. Customs and Border Protection (CBP) must adapt to the changing ways business is conducted due to the increasing volume of low-value packages, driven by direct-to-consumer e-commerce. The shift from traditional methods of importing via large, containerized shipments to small, low-value packages has presented new challenges for CBP. The growing volume of these small packages, coupled with the actionable data challenges CBP and other federal agencies face, requires new methods and resources in order for CBP to continue carrying out its mission of facilitating trade and enforcing trade laws."
