For orders outside the EU, local import duties, taxes, or tariffs may apply and are the responsibility of the customer
Hong Kong falls in the 12.5% flat Section 301 forced-labor tier (effective July 24, 2026). Major component manufacturing hub — many microbrands source cases and components from HK.
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.
