What Japan actually pays on cast-iron parts, not advanced beyond cleaning, and machined
Importers of HS 8411.91 (cast-iron parts, not advanced beyond cleaning, and machined ) from Japan actually paid 10% on the taxed portion of the value in 2026-06 — 0.17% 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% → 10%, with the largest single step +6.8pp in 2025-04. Measured from official US duty receipts · as-of 2026-06 · confidence: measured, not modelled. The HTS base rate is Free — importers actually paid 10%, so the trade-war overlay added 10 pts, measured at the border (not a summed rulebook estimate).
