What Japan actually pays on with internal combustion piston engine of a cylinder capacit
Importers of HS 8711.30 (with internal combustion piston engine of a cylinder capacit) from Japan actually paid 7.3% on the taxed portion of the value in 2026-06 — 7.3% across everything shipped, taxed or not. Measured from official duty receipts, not the rulebook: the statutory MFN base rate on this code is Free. Over the window the rate on the taxed portion moved null% → 7.3%, with the largest single step +11.2pp in 2025-09. Measured from official US duty receipts · as-of 2026-06 · confidence: measured, not modelled. The HTS base rate is Free — importers actually paid 7.3%, so the trade-war overlay added 7.3 pts, measured at the border (not a summed rulebook estimate).

HS 8711.30. The schedule base rate is
Free; importers from Japan actually paid 7.3% on the
dutiable value in 2026-06 — the trade-war overlay added 7.3 points, measured at the border. Measured, not modelled.
Over the window the collected rate moved % (2023-07) → 7.3% (2026-06), largest single step +11.2pp in 2025-09.
Landed cost vs the benchmark
Japan's lower duty (7.3% vs 17.5%) lets it price up to 9.5% above China at the factory and still match on duty-inclusive customs cost. But on the LATEST measured prices, China actually lands cheaper — $11.61/kg vs $24.24/kg (duty in, freight out).
