Catalytic preparations and reaction initiators, other
HSN 3815 19 00 (other reaction initiators, reaction accelerators, and catalytic preparations — not elsewhere specified or included) 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. Catalytic preparations with supported active metals, or those intended for petroleum refining or chemical synthesis, may fall under more specific tariff lines within Chapter 38 that carry distinct compliance obligations.
The residual nature of this tariff line — 'other' within heading 3815 — makes misclassification the primary import risk: a catalytic preparation that belongs under a named subheading may be reclassified on customs examination, triggering retrospective compliance and detention. Preparations that also qualify as hazardous chemicals may attract obligations under separate environmental or safety frameworks at the chapter level. Verify the product's chemical composition, intended industrial use, and active-component specification against the customs tariff before filing.
