SITCSection 7
U.S. imports of static converters (e.g., rectifiers) (SITC 77121) totaled $1.8B in April 2026, traded with 92 countries.
Importers of Static Converters (e.g., Rectifiers) paid $184.0M in duties in April 2026 — an effective duty rate of 13% on $1.4B in dutiable value, based on actual customs collections rather than the published tariff schedule. Static Converters (e.g., Rectifiers) imports of $1.8B in April 2026 ran 14% above the year-to-date monthly average of $1.5B.
Last updated: April 2026 dataRectifiers, inverters, converters, and regulated power supplies — collectively classified as static converters — are foundational components in renewable energy systems, industrial motor drives, data center power infrastructure, and consumer electronics. Unlike rotating machinery, static converters have no moving parts, relying on semiconductor devices to transform voltage, frequency, or current type. China-origin static converters across a wide range of HTS subheadings are subject to Section 301 tariffs, and solar inverters have drawn additional trade-remedy scrutiny, making origin and product-type documentation critical for importers serving the energy and electronics sectors.

Grid-tied and off-grid solar inverters are generally classified as static converters, though the specific HTS subheading depends on output characteristics such as single-phase versus three-phase and kVA rating. Solar inverters from certain origins have also been subject to antidumping and countervailing duty proceedings separate from Section 301 measures, so importers should verify the full trade-remedy landscape for their specific product and origin before entry.
The primary classification factors are the converter's function (rectifier, inverter, frequency converter, regulated power supply), its output power rating in kVA or watts, and whether it is single-phase or polyphase. Secondary factors such as input/output voltage range and intended application (e.g., telecommunications, industrial, consumer) may further determine the applicable HTS subheading. Manufacturer datasheets and technical drawings should accompany the entry documentation.
