Slag and ash n.e.c. in chapter 26; including seaweed ash (kelp) and ash and residues from the incineration of municipal waste

HS v2017 Code: 2621

About slag and ash n.e.c. in chapter 26; including seaweed ash (kelp) and ash and residues from the incineration of municipal waste

HS code 2621 covers a diverse range of slag, ash, and residues that are not classified elsewhere in chapter 26 of the Harmonized System. This industry plays a crucial role in the broader waste management and recycling ecosystem, as it processes various by-products and waste streams from industrial, municipal, and agricultural activities. The materials covered under this code have a wide range of applications, making it an important sector within the import/export trade landscape.

Production process

The production techniques for the materials classified under HS code 2621 can vary depending on the specific type of slag, ash, or residue being processed. In general, the key steps involve the collection, sorting, and processing of these materials. This may include mechanical separation, thermal treatment, or chemical processing to extract valuable components or prepare the materials for further use or disposal.

Production inputs

The main inputs required for the industries covered by HS code 2621 include the various waste streams and by-products from industrial, municipal, and agricultural activities. This can include items such as 2618 (Granulated slag (slag sand) from the manufacture of iron or steel), 2619 (Slag, dross (other than granulated slag), scalings and other waste from the manufacture of iron or steel), and ash from the incineration of municipal solid waste. Additionally, specialized equipment and machinery may be required for the processing and treatment of these materials.

Production outputs

The materials classified under HS code 2621 have a wide range of applications and can be consumed by various other industries. The processed slag, ash, and residues may be used as construction materials, soil amendments, or in the production of 2621 (Slag, dross (other than granulated slag), scalings and other waste from the manufacture of iron or steel). Additionally, the recovery of valuable components from these materials, such as metals or minerals, can lead to their use in other manufacturing processes or as feedstock for 2620 (Ash and residues (other than from the manufacture of iron or steel), containing metals or metal compounds), 2619 (Slag, dross (other than granulated slag), scalings and other waste from the manufacture of iron or steel), or 2618 (Granulated slag (slag sand) from the manufacture of iron or steel).
