HS code 8504.40 · Chapter 85

Static converters (power adapters, chargers)

Static converters including AC/DC power adapters, USB chargers, wall chargers and power supplies for electronic devices.

Current duty on this code

Base most-favoured-nation duty, pulled from the official tariff schedule when the destination publishes one. It does not include country-specific additional tariffs — for a US import those (Section 301, the 2025 reciprocal measures) can dwarf the base rate, and Kustaro shows them separately on a real classification.
