Below 6.6 kV

Ceramic electrical insulators rated below 6.6 kV

NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 8546 20 31 (ceramic electrical insulators rated below 6.6 kV) 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, bill of entry, commercial invoice, packing list. Ceramic insulators rated at or above 6.6 kV, or insulators of glass or composite materials, fall under distinct tariff lines within Chapter 85 that may carry separate compliance obligations.

No partner government agency notification covers this tariff line.

A word of counsel

The absence of compliance at this tariff line does not extend to higher-voltage ceramic insulator grades or to insulators of other materials classified elsewhere in Chapter 85. A customs re-classification — triggered, for example, by a voltage rating discrepancy in the test report or technical documentation — carries the risk of retrospective compliance, including detention pending resolution. Verify the voltage rating and material composition against the commercial invoice and technical datasheet before filing.

Frequently asked

Does HSN 8546 20 31 require any pre-import registration?

A valid Importer-Exporter Code is required for any commercial import; no product-specific registration applies to this tariff line.

What changes if the ceramic insulator is rated at or above 6.6 kV?

Higher-voltage ratings are classified under a distinct tariff line within Chapter 85 and may attract separate compliance obligations, with re-classification by customs triggering retrospective requirements.
