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 handles the byproducts and residues generated from various industrial and municipal processes. The materials classified under this code have a wide range of applications, making it an important segment of the import/export trade.

Production process

The production techniques for the materials covered under HS code 2621 can vary significantly depending on the specific type of slag, ash, or residue. In general, the key steps involve the collection, sorting, and processing of these materials. This may include activities such as incineration, pyrolysis, or other thermal treatment methods to extract valuable components or prepare the materials for further use or disposal.

Production inputs

The main inputs required for the industries covered under HS code 2621 include the raw materials themselves, which can come from a variety of sources, such as industrial processes, municipal waste, and seaweed harvesting. Additionally, these industries may require specialized equipment and machinery for the collection, sorting, and processing of the materials, as well as energy sources and other utilities to power the production facilities.

Production outputs

The outputs of the industries covered under HS code 2621 can be diverse, as the processed slag, ash, and residues can have a wide range of applications. These materials may be used as inputs for other industries, such as 2619 (Slag, dross (other than granulated slag), scalings and other waste from the manufacture of iron or steel), 2620 (Slag, ash and residues (other than from the manufacture of iron or steel), containing metals, arsenic or their compounds), or 2713 Petroleum coke, petroleum bitumen and other residues of petroleum oils or of oils obtained from bituminous minerals. Additionally, some of the outputs may be used in construction, agriculture, or other specialized applications.
