Mechanical seals

Mechanical seals for rotating and reciprocating equipment

NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 8484 20 00 (Mechanical seals) 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 articles under Chapter 84 — particularly machinery components subject to pressure equipment or boiler regulations — may attract compliance at the equipment or assembly level rather than at the individual seal tariff line.

No partner government agency notification covers this tariff line.

A word of counsel

The principal risk at this tariff line is misclassification: seals that are integral sub-components of a complete regulated machine (pumps, compressors, reactor vessels) may be re-assessed by customs as parts of that parent assembly, triggering the compliance regime that attaches to the parent equipment under Chapter 84. Retrospective duty recovery and detention pending re-classification are live consequences of that determination. Importers should document the standalone nature of the seal and its intended use before shipment.

Frequently asked

Does HSN 8484 20 00 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 mechanical seal is imported as part of a complete pump or compressor assembly?

A complete assembly is classifiable under its own Chapter 84 heading for that machine type, which may carry distinct compliance or duty treatment separate from the standalone seal tariff line.
