U.S. imports of Electrical Transformers (Other Than Liquid Dielectric), Power Handling Capacity Exceeding 1 KVA but Not Exceeding 16 KVA (HS 850432) totaled $17.6M in August 2026, imported from 52 countries.
Importers of Electrical Transformers (Other Than Liquid Dielectric), Power Handling Capacity Exceeding 1 KVA but Not Exceeding 16 KVA paid $4.4M in duties in August 2026, an average duty rate of 25.37% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataDry-type transformers in the 1–16 KVA range are widely used in commercial HVAC controls, machine tools, and light industrial power conditioning, and the entire heading resolves to a single 10-digit line (8504320000), making classification administratively simple once the liquid-dielectric and sub-1 KVA provisions are ruled out. Mexico and Canada are the leading US suppliers in this segment, with Vietnam and China also significant sources. The straightforward single-line structure means the primary classification risk lies in correctly establishing the rated KVA and confirming the transformer is dry-type rather than oil-filled.

Heading 8504.32 covers transformers exceeding 1 KVA but not exceeding 16 KVA, so a unit rated at exactly 16 KVA falls within this heading. A transformer rated above 16 KVA — even at 16.1 KVA — moves to heading 8504.33. The nameplate rated capacity is controlling, and importers should ensure invoices and technical data sheets reflect the precise rating to avoid misclassification.
Proximity to US industrial customers, USMCA preferential tariff treatment, and established manufacturing infrastructure for electrical equipment all contribute to Mexico and Canada's leading positions. For buyers evaluating supply-chain resilience, Vietnam is an emerging alternative, though lead times and logistics costs differ materially from North American sources.
