HS 8504 — Electrical transformers, static converters and inductors
Electrical transformers, static converters (such as rectifiers) and inductors — the heading most power adapters and chargers are classified under.
What falls under HS 8504?
Products commonly classified under this heading include:
- power adapters
- phone and laptop chargers
- USB power supplies
- voltage converters
These are examples, not a classification ruling. The exact code — and your duty rate — depend on the finished product and your destination country.
What moves your duty rate?
For goods under HS 8504, the rate you pay usually turns on:
- power rating (wattage)
- whether sold with the device it powers or separately
- destination country and energy-efficiency rules
Duties vary widely by the full commodity code and destination. This page is a starting point — verify the rate with your customs broker before you commit.
Estimate your landed cost
Once you have a duty rate from your broker or the tariff schedule, put it into the landed-cost calculator with your product cost and freight to see the all-in number per unit. For the category-specific questions — supplier checks, compliance, freight — see the buyer's guide: Importing electronics accessories from China.

How is a phone charger classified?
A standalone charger or power adapter is usually a static converter under heading 8504. If it ships inside a retail set with the phone, the set may be classified as a whole — describe how it is packaged.
