Colloidal or semi-colloidal graphite
Colloidal or semi-colloidal graphite
HSN 3801 20 00 (colloidal or semi-colloidal graphite) 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 products within heading 3801 — artificial graphite blocks, plates, and carbon-based paste preparations — occupy separate tariff lines that may carry distinct compliance under Chapter 38.
Colloidal and semi-colloidal graphite dispersions are sometimes formulated into lubricant preparations or industrial coatings that customs may re-classify under a more specific heading; re-classification triggers retrospective compliance and detention pending resolution. The distinction between a pure graphite dispersion and a finished preparation based on graphite or other carbon is the principal classification risk within heading 3801. Verify the product specification — particle size, carrier medium, intended end-use — against the customs tariff before shipment.
