Other chemical storage tanks
Chemical storage tanks, other than standard types
HSN 8419 89 17 (Other chemical storage tanks) 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. Pressure vessels, heat exchangers, or process equipment elsewhere in Chapter 84 that incorporate temperature-treatment functions may fall under sibling tariff lines attracting distinct compliance obligations.
Classification of industrial process equipment within Chapter 84 is fact-sensitive: a tank that also performs heating, cooling, or pressure containment may be pulled by customs into a more specific tariff heading that carries compliance requirements. Re-classification on examination triggers retrospective duty recovery and detention pending clearance. Importers should confirm the tank's design function, operating pressure, and temperature range against the customs tariff before relying on the absence of compliance at this tariff line.
