U.S. exports of Photovoltaic Semiconductor Devices (NESOI) (HS 854149) totaled $95.2M in August 2026.
Importers of Photovoltaic Semiconductor Devices (NESOI) paid $1.7M in duties in August 2026, an average duty rate of 2.84% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataPhotosensitive diodes, photosensitive transistors, optocouplers (optical coupled isolators, 8541498000), and other photovoltaic semiconductor devices not elsewhere specified serve critical roles in signal isolation, photodetection, and optoelectronic sensing across industrial automation, medical devices, and telecommunications. Italy and Japan lead US imports under this heading, with Taiwan, Canada, and Mexico also significant — a geographically diverse supply base that reflects the breadth of specialty optoelectronic manufacturing. Optocouplers in particular are widely used in safety-critical isolation circuits, making component-level traceability an important procurement consideration.

Optical coupled isolators have a dedicated 10-digit line (8541498000) within 854149, separate from photosensitive diodes (8541491050), photosensitive transistors (8541497080), and their respective chip/wafer lines. An optocoupler combines an LED emitter and a photosensitive detector in a single package to provide electrical isolation; its classification in 8541498000 is based on this combined optoelectronic isolation function rather than on either constituent device alone.
Photovoltaic cells (854142, 854143) are designed to convert light into electrical power for energy generation. Photosensitive devices under 854149 — such as photodiodes, phototransistors, and optocouplers — are designed to detect light or transmit signals optically, not to generate usable power. The intended function (power generation vs. signal detection or isolation) is the primary classification distinction, and it should be supported by the manufacturer's datasheet and product specifications.
