U.S. imports of Photovoltaic DC Generators, Output Not Exceeding 50 W (HS 850171) totaled $867K in August 2026, imported from 10 countries.
Importers of Photovoltaic DC Generators, Output Not Exceeding 50 W paid $92K in duties in August 2026, an average duty rate of 11.24% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Photovoltaic DC Generators, Output Not Exceeding 50 W imports of $867K in August 2026 ran 52% above the year-to-date monthly average of $572K.
Last updated: August 2026 dataSmall-wattage photovoltaic DC generators — solar panels and integrated PV modules producing 50 W or less — serve consumer electronics charging, remote sensing, and off-grid lighting markets where compact form factor matters more than bulk power output. Vietnam is the leading US import source for this heading, reflecting the significant manufacturing shift in solar component production to Southeast Asia in recent years; China and Taiwan are also notable suppliers. Goods from China in this category may carry Section 301 exposure, and solar products from multiple Southeast Asian countries have been subject to antidumping and circumvention investigations, making origin documentation a compliance priority. The heading resolves to a single 10-digit line, 8501710000.

US antidumping and countervailing duty orders on crystalline silicon photovoltaic cells and modules have been extended to cover circumvention through several Southeast Asian countries. Importers should verify whether their specific product and country of origin are covered by any active orders or circumvention findings, and obtain appropriate certifications or scope rulings from CBP or the Department of Commerce before shipment.
The 50 W threshold is based on the module's rated maximum power output (Pmax) under standard test conditions (STC), as stated in the manufacturer's datasheet. Modules with a Pmax at or below 50 W fall under 850171 (single line 8501710000), while those exceeding 50 W are classified under 850172, which is further subdivided by output level. Importers should retain STC test reports to support classification.
