About importing lithium-ion battery from China

US duties on lithium-ion battery are estimated by stacking the product's normal (MFN) tariff with the additional layers that apply to goods from China. In the current 2026 schedule, Lithium-ion battery carries an MFN rate of 3.4%, plus a Section 301 China layer and a forced-labor/security base where applicable.

On top of duty, US Customs charges a Merchandise Processing Fee (MPF) of 0.3% (min $34.58, max $670.86, effective 1 October 2026) and, for ocean freight, a Harbor Maintenance Fee (HMF) of 0.1%. The ad-valorem MPF rate is unchanged; only the minimum and maximum rose for fiscal year 2027.
