HS Code for Municipal waste ash

Municipal waste ash is classified under HS code 2621.10 because it represents the solid residue remaining after the incineration of municipal waste. Chapter 26 of the Harmonized System is dedicated to ores, slag, and ash. Within this chapter, heading 2621 serves as a residual category for slag and ash that are not elsewhere specified. Subheading 2621.10 is specifically designated for ash and residues resulting from the incineration of municipal waste. This classification is determined by the origin of the ash—specifically, the combustion of household, commercial, and institutional waste collected by or on behalf of municipal authorities. The classification remains consistent regardless of whether the ash is intended for disposal in landfills or for recovery operations, such as use in construction materials or metal extraction. The chemical composition of this ash typically includes various oxides, silicates, and trace metals, but its classification is driven by its source as a byproduct of municipal waste incineration processes rather than its chemical purity.

Products Included

• Incinerator bottom ash (IBA) from municipal plants
• Fly ash resulting from municipal waste combustion
• Boiler slag from municipal waste incinerators
• Combined ash residues from municipal waste-to-energy facilities

Common Misclassification

Municipal waste ash is frequently confused with other types of ash classified under 2621.90. While 2621.10 is specific to municipal waste, 2621.90 covers coal ash, wood ash, and ash from other industrial processes. Another common error is attempting to classify these residues under heading 3825, which covers residual products of the chemical or allied industries. However, because 2621 specifically mentions ash from municipal waste incineration, General Interpretative Rule 1 dictates that the specific heading takes precedence over more general waste headings.

FAQ

What is the HS code for municipal waste ash?

The HS code for municipal waste ash is 2621.10, which specifically covers ash and residues from the incineration of municipal waste.

Does this code include ash from hazardous industrial waste?

No, ash from the incineration of hazardous waste is generally classified under 2621.90 or within Chapter 38, depending on its specific chemical nature and origin, as 2621.10 is strictly for municipal waste.
