Amplifiers
Electronic integrated circuits functioning as amplifiers
HSN 8542 33 00 (amplifier integrated circuits) 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 electronic integrated circuits within Chapter 85 — particularly processors, controllers, and memories — may fall under sibling tariff lines that carry compliance obligations, so precise classification of the IC function matters.
The absence of compliance at this tariff line applies specifically to ICs classified by their amplifier function; re-classification by customs to a different functional category within heading 8542 triggers retrospective compliance, including potential detention pending the applicable licence or certificate. Importers should confirm that the device's primary function — as declared in datasheets and invoices — is amplification, not processing, switching, or memory. Mismatched functional descriptions are the most common ground for customs re-examination in Chapter 85 electronics.
