Static converters, "other". Power banks with a battery are classified differently (heading 8507).
Section 301 list status is taken from the USITC "China Tariffs" reference (last updated July 28, 2026). Background on the lists is on USTR's Section 301 tariff actions page. Other duties on goods from China, such as IEEPA duties under U.S. notes 2(u)/2(v) to chapter 99, change often and are not included here; check the current HTS chapter 99 before you price. Exclusions, if any, are listed in U.S. note 20.
Sourcing notes
- Ask for UL 62368-1 or equivalent safety listing and FCC Part 15 test reports.
- Check DOE efficiency marking for external power supplies.
- Counterfeit certification marks are common; verify the listing number on the lab's own site.
These are common checks, not a full compliance list. Requirements depend on your exact product and sales channel.
