Thyristors
Thyristors, other than photosensitive devices
HSN 8541 30 10 (Thyristors) 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. Certain other semiconductor devices within Chapter 85 — including photovoltaic cells, LEDs, and assembled modules — may carry compliance requirements under sibling tariff lines.
The absence of compliance at this tariff line does not extend to related semiconductor devices classified elsewhere in Chapter 85: photosensitive thyristors, diacs, and triacs fall under a distinct tariff line and may attract separate regulatory treatment. Re-classification by customs on examination — based on photosensitivity, assembly state, or end-use — triggers retrospective compliance and potential detention. Verify the product specification against the customs tariff, particularly the photosensitive/non-photosensitive distinction, before relying on the absence of compliance here.
