Thermistors

Thermistors, variable resistors for temperature sensing

NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 8533 40 30 (Thermistors) 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 components under Chapter 85 — particularly fixed resistors, certain capacitors, and assembled electronic modules — may fall under tariff lines that do carry compliance obligations.

No partner government agency notification covers this tariff line.

A word of counsel

The principal importer risk at this tariff line is misclassification: thermistors incorporated into or presented with a larger assembly may be re-classified by customs under the finished-product heading, which can carry its own compliance regime. Retrospective compliance on re-classification may result in detention pending the relevant licence and recovery of differential duty. Verify that the goods are imported as discrete components, not as part of a sub-assembly, before relying on the absence of compliance here.

Frequently asked

Does HSN 8533 40 30 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 thermistor is integrated into a finished electronic assembly or module?

A finished assembly may be classified under a different heading within Chapter 85 that carries its own compliance requirements, triggering retrospective obligations on customs re-classification.
