Cost sharing deals work when they are formula based, time boxed, and tied to the actual duty paid. ## How do importers claim duty refunds when goods are returned or destroyed? Duty paid on goods that are returned, rejected, or destroyed is not always lost. Refund, drawback, and relief mechanisms exist, but each demands proof, deadlines, and paperwork created before the goods disappear. ## How do importers audit past entries for duty overpayments they can recover? Importers routinely overpay duty through classification errors, missed preferences, and valuation mistakes, and a structured audit of past entries turns those errors into refund claims within the correction windows customs allows. ## How do importers prepare for a de minimis rule change before it lands? De minimis rules let low value shipments enter with simplified handling and, in many cases, no duty. When governments tighten those rules, high volume low value import models change overnight.
