U.S. imports of Semiconductor Diodes (Excluding Photosensitive and LED) (HS 854110) totaled $49.9M in August 2026, imported from 49 countries.
Importers of Semiconductor Diodes (Excluding Photosensitive and LED) paid $4.8M in duties in August 2026, an average duty rate of 10.52% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataZener diodes, microwave diodes, and general-purpose semiconductor diodes — split by current-carrying capacity at the 0.5-ampere threshold — are foundational components in power management, signal processing, and RF circuits across consumer, industrial, and automotive electronics. China and Taiwan together dominate US import flows under this heading, with Malaysia and Japan rounding out the primary supply base. Section 301 tariffs apply to imports from China, making origin documentation and first-sale valuation practices particularly important for cost management.

The US schedule classifies general semiconductor diodes (other than photosensitive) into those rated at or below 0.5 A (8541100070) and those above 0.5 A (8541100080). Zener diodes (8541100050) and microwave diodes (8541100060) have their own dedicated lines, as do chips and wafers for non-photosensitive diodes (8541100040). The correct line depends on the device's rated current and functional type as documented in the manufacturer's datasheet.
Manufacturer datasheets specifying device type (Zener, microwave, rectifier, etc.) and rated forward current are the primary classification evidence. For mixed shipments, a packing list that itemizes part numbers by type and current rating allows each line item to be assigned to the appropriate 10-digit HTS code, reducing the risk of a blanket NESOI classification that could be challenged at entry.
