U.S. imports of Nickel-Metal Hydride Storage Batteries (HS 850750) totaled $59.6M in August 2026, imported from 35 countries.
Importers of Nickel-Metal Hydride Storage Batteries paid $6.2M in duties in August 2026, an average duty rate of 9.31% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Nickel-Metal Hydride Storage Batteries imports of $59.6M in August 2026 ran 12% above the year-to-date monthly average of $53.2M.
Last updated: August 2026 dataNickel-metal hydride (NiMH) rechargeable batteries occupy a well-established niche in hybrid electric vehicles, consumer electronics, and industrial applications where cadmium-free chemistry and moderate energy density are priorities. All US imports under this heading are consolidated into a single 10-digit line (8507500000), simplifying entry but placing the classification burden on distinguishing NiMH from the closely related nickel-cadmium (8507.30) and lithium-ion (8507.60) headings. Japan leads US supply — a legacy of its early dominance in hybrid-vehicle battery technology — with China and the United Kingdom also contributing. Importers should document the specific electrochemical system clearly, as NiMH and NiCd cells can appear physically similar.

The distinction is electrochemical: NiMH batteries use a hydrogen-absorbing alloy anode, while NiCd batteries use a cadmium anode. Manufacturer specifications, material safety data sheets, and IEC battery designation codes (e.g., HR for NiMH, KR for NiCd) are the primary documentation CBP will look to. Physical appearance alone is insufficient, as both chemistries appear in similar cylindrical and prismatic formats.
Under the current US schedule, all NiMH storage batteries — whether automotive-grade hybrid-vehicle packs or consumer AA/AAA replacement cells — are consolidated into a single 10-digit line (8507500000). Unlike the lead-acid and nickel-cadmium headings, there is no separate EV-power-source subheading for NiMH, so end-use does not change the classification, though it may affect admissibility or safety-standard requirements.
