CBP tightens IOR verification from 18 Sep; copper smelt/cast data rejected from 14 Sep

Summary

From 18 September CBP will verify Importer of Record (Form 5106) details, rejecting PO boxes or agent addresses-false data voids the IOR and blocks clearance. From 14 September entries lacking copper smelt and cast country for HTS 8544.42/8544.49 goods are rejected. Both steps raise compliance burden for importers and forwarders.
