With a dissipation rate of less than 1 W
Transistors with dissipation rate below 1 W
HSN 8541 21 00 (transistors with a dissipation rate of less than 1 W) 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, light-emitting diodes, and higher-dissipation transistors — may fall under tariff lines that do carry compliance obligations.
The principal importer risk at this tariff line is misclassification: transistors with a dissipation rate of 1 W or above are classified separately within heading 8541 and may attract distinct compliance requirements. Semiconductor devices assembled into modules, panels, or finished consumer electronics may also trigger product-specific obligations under Chapter 85. Re-classification on customs examination triggers retrospective compliance, including detention pending the applicable certification.
