Tariff situation in flux

Current Rate

16%

6% HTS + 10% Section 122

Est. Duty

$400–$17600

on $2500–$110000 watch

⚠ Current Section 122 rate expires Jul 24, 2026 — rates may change.

Exclusively available to Japanese customers. Requires local Japanese credit card and Japanese shipping address.

Previous 15% reciprocal deal now in limbo post-SCOTUS. Currently flat 10% Section 122. Japanese movements (Miyota, Seiko) are components, not finished watches — tariff applies to where the watch is assembled, not where the movement is from.

Tariffs are assessed based on where the watch is assembled, not where individual components originate. A watch with a Japanese movement assembled in the US incurs no import duty.
