Semiconductor-based transducers
Semiconductor-based transducers (pressure, temperature, chemical sensors)
HSN 8541 51 00 (Semiconductor-based transducers) is not covered by a Bureau of Indian Standards Quality Control Order and carries no Partner Government Agency clearance requirement at the tariff-line level. Import follows the standard customs procedure: Importer-Exporter Code (IEC), bill of entry, commercial invoice, packing list. Other semiconductor devices within Chapter 85 — including photovoltaic cells, LEDs, and certain diodes and transistors — may fall under tariff lines that do carry compliance obligations.
Chapter 85 is one of the most actively regulated chapters in India's Quality Control Order framework; neighbouring tariff lines covering solar photovoltaic cells, certain LEDs, and other semiconductor devices carry mandatory BIS certification. A misclassification — or a product description broad enough to invite re-examination — can result in detention pending re-classification and retrospective compliance. Verify that the product specification, including sensing principle and application, squarely supports classification at 8541 51 00 before shipment.
