Audio visual stereo encoders
Audio-visual stereo encoders for signal processing
HSN 8543 70 94 (audio-visual stereo encoders) 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 electrical apparatus within Chapter 85 — particularly wireless transmission equipment, radio-frequency devices, and certain consumer electronics — may fall under sibling tariff lines that do carry BIS or Wireless Planning and Coordination compliance.
The absence of compliance at this tariff line is contingent on the product being correctly classified as a stereo encoder and not re-characterised on examination as a broadcasting transmitter, wireless device, or radio apparatus — categories within Chapter 85 that carry mandatory approvals. Re-classification by customs to a more specific or differently regulated tariff line triggers retrospective compliance, including detention pending the relevant licence. Verify the product's signal-transmission method and intended use before relying on the absence of compliance.
