§ FAQFrequently asked
- How do I confirm whether HTS 7304.59.80.45 fits my goods?
- Having a wall thickness less than 12.7 mm. Compare the complete hierarchy and notes with materials, function and imported form. Neighboring entries support comparison, not interchangeable classifications.
- Can I use this amount as final total duty?
- Conditional estimate (incomplete). The example uses an illustrative value. Supply actual origin, value and policy facts in the workbench, keeping confirmed components, estimates and unevaluated items separate. Unresolved conditions are not zero duty.
- Does an AD/CVD reference establish shipment coverage?
- 14 case references were found, but an HTS reference alone does not establish coverage. Review scope, origin and producer conditions separately; cash deposits are not automatically calculated here.
- How do I check the data version?
- Base HTS data updated: September 29, 2026; release: 2026HTSRev20. A refresh date is not the effective date of every policy; check USITC and the relevant original rules.
