MFN Base Rate (General)8.8¢/kg + 20%
Non-ad-valorem component: 8.8¢/kg (not included in the % total, enter quantity below)
MFN rate includes 8.8¢/kg. Enter quantity and customs value to convert the per-unit fragment into an ad-valorem equivalent (AVE) so the displayed total reflects the full rate.
AVE% = (per-unit amount x quantity) ÷ customs value x 100. Quantity 0 leaves the specific component out of the percent total.
Estimate the Merchandise Processing Fee and Harbor Maintenance Fee separately from the ad-valorem duty stack. Fees are charged on entered value, not as a percentage on top of the tariff.
Simulation, not a filing basis. This tool models the ad-valorem duty stack for directional analysis. It does NOT replace the official HTSUS, a licensed customs broker, or Commerce / USTR / CBP rulings. The total does not include antidumping or countervailing duties (AD/CVD), non-ad-valorem specific duty components, preferential FTA rates that require origin qualification, Chapter 98 provisions, Chapter 99 exclusions, or §232 absolute-quota fill status. Rates change frequently. Before entering any commercial shipment, verify the applicable rate in the USITC HTSUS and confirm with CBP or a licensed customs broker.
