Chapter 91 classification notes

Classification depends on the display type (analog vs digital), case material (precious metal vs base metal), and movement type (mechanical vs quartz). Luxury watches face IP enforcement and counterfeit seizures. Swiss origin marking has specific legal requirements.

Frequent misclassification in this chapter

Smart watches may classify under 8517 (telecom apparatus) rather than 9102 (watches) depending on their primary function. Watch cases with precious metal plating — classify by the base metal, not the plating.

Classification certainty

The 6-digit level shown here is the internationally harmonised layer. Duty rates attach to national 8-10 digit tariff lines, which differ by country — use the duty calculator for lane estimates. For binding certainty, request a ruling from the destination customs authority.
