HS v2022 Code: 3825

About residual products of the chemical or allied industries, not elsewhere specified or included; municipal waste; sewage sludge; other residual products.

HS code 3825 covers a diverse range of residual products from the chemical and allied industries that do not fit into other more specific classifications. This industry plays a crucial role in the broader economy by managing and repurposing waste streams that would otherwise pose environmental and logistical challenges. The products covered under this code are essential for sustainable waste management and the circular economy.

Production process

The production techniques for the items under HS code 3825 can vary widely depending on the specific type of residual product. In general, the processes may involve collection, sorting, treatment, and in some cases, further processing or conversion of the waste materials into usable products. This can include techniques such as incineration, pyrolysis, distillation, and chemical or biological treatment.

Production inputs

The main inputs for the industries covered by HS code 3825 are the various waste streams and residual products generated by other manufacturing and municipal activities. This can include things like used solvents, spent catalysts, municipal solid waste, sewage sludge, and other by-products or leftover materials from chemical, industrial, and commercial processes. The specific inputs will depend on the type of residual product being produced.

Production outputs

The outputs of the industries under HS code 3825 can be quite diverse, as the residual products may be further processed, repurposed, or disposed of in various ways. Some of the outputs may include 3824 (Prepared binders for foundry moulds or cores; chemical products and preparations of the chemical or allied industries (including those consisting of mixtures of natural products), not elsewhere specified or included), 3915 Waste, parings and scrap, of plastics, and 3821 (Prepared culture media for the development or maintenance of micro-organisms (including viruses and the like) or of plant, human or animal cells).
