Chemical storage tanks with a total internal (geometric) volume greater than 0.1 m³ (100 l)
Chemical storage tanks, internal volume greater than 100 litres
HSN 8419 89 16 (chemical storage tanks with a total internal volume greater than 0.1 m³) 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. Other equipment under Chapter 84 designed for temperature-treatment processes — such as pressure vessels or heat exchangers — may fall under tariff lines that carry distinct compliance obligations.
The absence of compliance at this tariff line applies to chemical storage tanks imported for general industrial use; tanks that function as pressure vessels or that form part of a regulated process plant may be re-classified to a tariff line carrying statutory obligations, triggering retrospective compliance and detention pending resolution. Importers should verify that the product specification — design pressure, material of construction, intended process use — aligns precisely with this tariff line before relying on the absence of compliance.
