Gaskets and joints of metal sheeting combined with other material
HSN 8484 10 90 (gaskets and similar joints of metal sheeting combined with other material, or of two or more layers of metal — residual category) 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. Gaskets and sealing components destined for specific end-use equipment — such as pressure vessels or boilers under Chapter 84 — may attract compliance obligations at the equipment or assembly level rather than the component tariff line.
The principal risk at this tariff line is misclassification: mechanical seals (separately classified within heading 8484) and gasket sets or assortments put up in pouches each occupy distinct tariff lines that may carry differing duty rates or compliance treatment. Where a customs officer re-classifies the goods to a more specific line on examination, retrospective compliance and detention pending re-assessment follow. Importers should verify that the product specification — materials of construction, layering, and form of presentation — precisely matches the residual 'Other' category before shipment.
