When consolidation pays for itself
If you buy from several suppliers, shipping each order separately means paying the fixed costs of freight and a customs entry more than once. Since the $800 de minimis exemption was withdrawn, every one of those shipments needs a full entry — which made splitting orders markedly more expensive than it was two years ago.
Orders wait for each other here at no cost for the first 10 days, which in practice covers most consolidation. The goods then travel as a single consignment — see freight forwarding from China to the USA for rates and transit times.
