SITCSection 7
U.S. imports of parts of electric power machinery (excluding rotating generating equipment) (SITC 77129) totaled $348.6M in April 2026, traded with 64 countries.
Importers of Parts of Electric Power Machinery (Excluding Rotating Generating Equipment) paid $39.8M in duties in April 2026 — an effective duty rate of 16% on $245.6M in dutiable value, based on actual customs collections rather than the published tariff schedule. Parts of Electric Power Machinery (Excluding Rotating Generating Equipment) imports of $348.6M in April 2026 ran 10% below the year-to-date monthly average of $389.0M.
Last updated: April 2026 dataReplacement and production components for transformers, static converters, ballasts, and inductors — but not for rotating generators or motors — are captured under this residual parts heading, serving utilities, industrial OEMs, and MRO distributors. The exclusion of rotating electric plant parts is a critical scope boundary: parts for generators and motors are classified elsewhere, and misclassification between these categories is a common audit finding. Given the breadth of parent apparatus covered, importers must identify the specific equipment type for which a part is destined, as Section 301 tariff exposure and any applicable AD/CVD orders vary significantly by parent apparatus and origin.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The key question is whether the parent apparatus is a static device (transformer, converter, ballast, inductor) or a rotating machine (generator, motor). Parts designed and used exclusively with static power equipment belong here, while parts for rotating machinery are classified under separate HTS headings. When a component is used in both static and rotating equipment, the principal-use rule applies, and manufacturer documentation identifying the primary intended application is essential.
Importers should first confirm whether any active antidumping or countervailing duty orders cover the specific part type and country of origin by checking the Department of Commerce's AD/CVD order database. If an order may apply, a scope ruling request can provide certainty before large-volume entries. Additionally, Section 301 tariff applicability should be verified at the HTS subheading level, and a licensed customs broker should review entry documentation to ensure correct classification and deposit of estimated duties.
