Scenario: A US ecommerce importer buys industrial LED control units routed through Rotterdam from a supplier in Netherlands. The importer has an invoice, product specification, origin evidence, transport mode, and a working HTS candidate but has not yet verified the final rate.
- Confirm what the product is made of, what it does, and how it is constructed or presented for retail.
- Check whether the evidence supports Netherlands as manufacturing origin rather than only the sale or dispatch location.
- Verify the complete US HTS line and applicable general or special rate in the current USITC schedule.
- Establish customs value from the transaction records and record any required additions.
- Check product-and-origin-specific additional measures separately; enter zero only after the check, not by assumption.
- Add applicable entry, vessel, brokerage, and carrier fees as separately labeled amounts.
- Save the source date and treat the result as an estimate for purchasing or pricing, not as a CBP determination.
Treat Rotterdam, a Dutch warehouse, or an EU distribution hub as ship-from facts, not automatic Dutch origin. For electronics and machinery, record function, power, components, and whether the item is a complete machine, part, or accessory. Keep anti-dumping, countervailing, Section 232, and other product-specific measures as separate verification questions.
