Fly ash|HS Code

Fly ash harmonized system code

Product Overview Fly Ash, classified under HS Code 2621, is a by-product obtained from the combustion of pulverized coal in electric power generating plants. This high-quality material is characterized by its spherical shape, grey or light tan color, and fine particle size, typically falling within 10-100 micrometers. The product is subjected to extensive processing to ensure low carbon content, high fineness, and improved pozzolanic activity. Under HS Code 2621, Fly Ash is further classified into subcategories such as ash and residues from the incineration of municipal waste and ash and residues containing arsenic, metals, or their compounds. Fly Ash is predominantly used in the construction industry as a supplementary cementitious material, enhancing the performance of concrete and offering significant environmental benefits. Its value proposition lies in its cost-effectiveness, quality improvement capabilities, and sustainability quotient. HS Code Classification & Trade Specifications The complete HS Code structure for Fly Ash is 2621.10.00. This includes Chapter 26 (ores, slag, and ash), Heading 2621 (other slag and ash, including seaweed ash), and Subheading 2621.10 (ashes and residues from the incineration of municipal waste). The classification rationale for Fly Ash under this code is due to its production process involving incineration and its primary usage as a residue in varied industries. In terms of trade, Fly Ash is commonly packaged in large, moisture-proof bags or bulk containers to preserve its quality during transportation. The shipping requirements adhere to the National and International Standards for Fly Ash Used in Concrete (ASTM C618 and EN450 respectively). These standards specify the chemical and physical requirements, ensuring the product's suitability for use in cement and concrete production. It's crucial to note that the Fly Ash's trade description should comply with World Trade Organization and customs documentation standards, highlighting its specifications, processing levels, and quality attributes.

Fly ash Chapter Note

1.- This Chapter does not cover : (a) Slag or similar industrial waste prepared as macadam (heading 25.17); (b) Natural magnesium carbonate (magnesite), whether or not calcined (heading 25.19); (c) Sludges from the storage tanks of petroleum oils, consisting mainly of such oils (heading 27.10); (d) Basic slag of Chapter 31; (e) Slag wool, rock wool or similar mineral wools (heading 68.06); (f) Waste or scrap of precious metal or of metal clad with precious metal; other waste or scrap containing precious metal or precious metal compounds, of a kind used principally for the recovery of precious metal (heading 71.12 or 85.49); or (g) Copper, nickel or cobalt mattes produced by any process of smelting (Section XV). 2.- For the purposes of headings 26.01 to 26.17, the term “ores” means minerals of mineralogical species actually used in the metallurgical industry for the extraction of mercury, of the metals of heading 28.44 or of the metals of Section XIV or XV, even if they are intended for non-metallurgical purposes. Headings 26.01 to 26.17 do not, however, include minerals which have been submitted to processes not normal to the metallurgical industry. 3.- Heading 26.20 applies only to : (a) Slag, ash and residues of a kind used in industry either for the extraction of metals or as a basis for the manufacture of chemical compounds of metals, excluding ash and residues from the incineration of municipal waste (heading 26.21); and (b) Slag, ash and residues containing arsenic, whether or not containing metals, of a kind used either for the extraction of arsenic or metals or for the manufacture of their chemical compounds.
