HSN and GST Rate for Miscellaneous Chemical Products - HSN Chapter 38

In this article, we explore the HSN code and GST rate for miscellaneous chemical products categorized under Chapter 38 of the HSN Code. HSN Chapter 38 specifically does not include:

  1. Artificial graphite (heading 3801);
  2. Insecticides, rodenticides, fungicides, herbicides, anti-sprouting products and plant-growth regulators, disinfectants, and similar products as described in heading 3808;
  3. Fire-extinguisher charges or fire-extinguishing grenades (heading 3813);
  4. Mixtures of chemicals with foodstuffs or nutritive substances used in human food preparation (generally, heading 2106);
  5. Ash and residues containing metals, arsenic or their mixtures, aligning with Note 3(a) or 3(b) to Chapter 26 (heading 2620);
  6. Medicaments (heading 3003 or 3004);
  7. Spent catalysts used for extracting base metals or manufacturing chemical compounds of base metals (heading 2620), those mainly for recovering precious metals (heading 7112), or catalysts comprising metals or metal alloys in forms such as finely-divided powder or woven gauze (Section XIV or XV).

For the classification of certified reference materials, heading 3822 has priority over other headings within the Schedule, except for products of Chapter 28 or 29.

Key Inclusions under Heading 3824

Heading 3824 comprises goods not classified under any other heading in this Schedule, such as:

  • Cultured crystals (excluding optical elements) weighing 2.5g or more each, of magnesium oxide or halides of alkali or alkaline-earth metals;
  • Fusel oil; Dippel’s oil;
  • Retail-packaged ink removers;
  • Retail-packaged stencil correctors, other correcting fluids, and correction tapes (excluding those of heading 9612); and
  • Fusible ceramic firing testers, such as Seger cones.

Definition of Municipal Waste

Across the Schedule, “municipal waste” is defined as waste typically gathered from households, hotels, restaurants, hospitals, shops, offices, roads, and construction and demolition sites. It generally includes a diverse mix of materials like plastics, rubber, wood, paper, textiles, glass, metals, food scraps, and furniture pieces. However, it excludes:

  • Individual recovered materials from waste such as plastics, rubber, wood, and paper;
  • Industrial waste;
  • Waste pharmaceuticals; and
  • Clinical waste.

Classification of Other Wastes under Heading 3825

"Sewage sludge" under heading 3825 is identified as sludge from urban effluent treatments, encompassing pre-treatment waste and unstabilized sludge, while stabilized sludge suitable for fertilizers is categorized under Chapter 31.

The term “other wastes” under this heading applies to:

  1. Contaminated medical waste containing pathogens and requiring unique disposal methods;
  2. Waste organic solvents;
  3. Metal pickling liquor wastes, hydraulic fluids, brake fluids, and anti-freeze fluids; and
  4. Other chemical or allied industry wastes.

However, wastes composed chiefly of petroleum oils or bituminous mineral oils belong to heading 2710.
