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

HS code 262190 covers a diverse range of slag and ash materials that are not classified elsewhere in chapter 26 of the Harmonized System. This industry plays a crucial role in the recycling and repurposing of industrial byproducts, contributing to the circular economy and reducing waste. The materials covered under this code have a wide range of applications, from construction materials to agricultural inputs, making it an important component of various industrial supply chains.

The production of slag and ash covered under HS 262190 typically involves the collection, processing, and refinement of industrial byproducts. This can include the separation of different types of slag and ash, as well as the removal of impurities and the preparation of the materials for their intended uses. The specific techniques employed may vary depending on the source and composition of the raw materials, as well as the desired end-product characteristics.

The main inputs required for the production of slag and ash under HS 262190 include the industrial byproducts themselves, such as slag from metal smelting, ash from power plants, and seaweed ash (kelp). Additionally, the industry may require specialized equipment for the collection, sorting, and processing of these materials, as well as energy sources and water for various stages of production.

The outputs of the HS 262190 industry include a wide range of slag and ash products that can be used in various applications. These may include construction materials like cement and concrete additives, agricultural inputs like soil amendments, and raw materials for other industrial processes. The specific outputs and their end-uses will depend on the composition and properties of the slag and ash produced. Some of the other HS codes that may consume the outputs of this industry include 2621 (Slag, dross (other than granulated slag), scalings and other waste from the manufacture of iron or steel), 2622 (Ash and residues (other than from the manufacture of iron or steel), containing metals or metallic compounds), and 3105 Mineral or chemical fertilizers containing two or three of the fertilizing elements nitrogen, phosphorus and potassium; other fertilizers; goods of this chapter in tablets or similar forms or in packages of a gross weight not exceeding 10 kg.
