Customs value and origin
The duty you pay hangs on two things: the value you declare and where the goods originate. Build a defensible customs value, test First Sale and tariff-engineering angles, prove preferential or marked origin, and see whether drawback, inward processing or a bonded warehouse can suspend or reclaim the duty entirely.
- Customs Value Builder →Dutiable customs value under WTO Article VII + WCO TAR Article 8 adjustments.
- US First Sale Rule Eligibility Checker →Does your multi-tiered import (factory to middleman to US importer) qualify for First Sale valuation under the Nissho Iwai three-prong test — duty saved by declaring the earlier sale price, and the CBP paper trail.
- Tariff Engineering Classification →Where legal tariff engineering can lower the duty rate for a classification — and where reclassification crosses into fraud.
- Preferential Origin Checker →Can your shipment claim 0% preferential duty under USMCA, EU-UK TCA, or another FTA — rules-of-origin + proof-of-origin check.
- US Country of Origin Marking Checker →Must your imported goods carry US country-of-origin marking, how to mark them (legible, indelible, conspicuous, in English), and whether a J-list exception applies — to avoid the 10% marking duty.
- US Duty Drawback Feasibility Checker →Reclaim up to 99% of the US customs duty paid on imported goods later exported or destroyed — eligibility check and refund estimate.
- EU Inward Processing Relief Checker →Do your non-EU goods qualify for EU Inward Processing — which suspends import duty and VAT on goods processed in the EU and re-exported — and how much it suspends for your shipment.
- US Bonded Warehouse vs Direct Entry Checker →Store a US import in a customs bonded warehouse (defer duty up to 5 years, pay nothing on the re-exported share) or clear it on a direct consumption entry — with the cashflow math.
