Start by classifying the goods under their exact 10-digit HTS code, then check whether that specific line appears on the Trade Agreement Between the United States and Japan staged-reduction schedule — unlike a comprehensive FTA, USJTA only covers a negotiated list of agricultural goods and select industrial categories like machine tools, fasteners, and musical instruments, so most Japanese manufactured goods don't qualify. If the HTS line isn't on that list, the shipment clears at the standard MFN (Column 1) rate, which this calculator estimates at a blended baseline of 0% pending your product's exact classification. Either way, add the Merchandise Processing Fee (0.3464% ad valorem) — USJTA does not waive it — plus the Harbor Maintenance Fee for ocean shipments, and any applicable Section 232 rate for steel, aluminum, or automotive products, to reach total landed cost.

There's no single flat "Japan rate" — duty is set per 10-digit HTS classification, and Japan doesn't have a comprehensive free trade agreement with the US the way Canada or South Korea does. Trade Agreement Between the United States and Japan eliminates or reduces duty only on a negotiated list of tariff lines, mostly agricultural products and specific industrial categories, so most Japanese-origin vehicles, electronics, and machinery still clear at standard MFN rates outside that agreement. This calculator uses a blended baseline of 0% to approximate the MFN rate pending your product's exact classification; automotive and metals categories in particular should be checked separately for Section 232 exposure, since that program can apply on top of or instead of the MFN rate.

Regardless of whether your product qualifies for USJTA preference, every formal entry carries a Merchandise Processing Fee of 0.3464% of the customs value (subject to statutory minimum and maximum caps) — USJTA is a targeted tariff-reduction program, not a blanket agreement, so it does not exempt qualifying shipments from MPF the way USMCA does for Canada and Mexico. Ocean shipments add a Harbor Maintenance Fee on top of that. Because the Section 321 de minimis exemption is suspended and written into federal regulation (19 CFR 10.151 and 19 CFR 145.31) effective June 24, 2026, there's no value threshold left that lets a shipment skip customs entry and fees entirely — every shipment from Japan now requires a real customs entry regardless of value.

It depends on the HTS classification, not on the fact that the goods are Japanese. If your product's 10-digit HTS line is one of the specific agricultural or industrial categories (such as machine tools, fasteners, or musical instruments) covered by Trade Agreement Between the United States and Japan's staged-reduction schedule, and the country of origin and country of export are both Japan, duty is eliminated or reduced according to that schedule. Everything else — which is most Japanese manufactured goods, since USJTA's scope is deliberately narrow — pays the standard MFN rate for its HTS classification, currently estimated by this calculator at a blended baseline of 0%. Goods transshipped or exported from a third country lose USJTA eligibility even if originally manufactured in Japan, so the export country matters as much as the origin country.
