Slag, ash and residues; (not from the manufacture of iron or steel), containing mainly lead; leaded gasoline sludges and leaded anti-knock compound sludges

HS v2017 Code: 262021

About slag, ash and residues; (not from the manufacture of iron or steel), containing mainly lead; leaded gasoline sludges and leaded anti-knock compound sludges

HS code 262021 covers a range of industrial waste and residues that contain primarily lead. This includes slag, ash, and sludges generated from various manufacturing processes, particularly those involving leaded gasoline and anti-knock compounds. These materials are an important part of the broader waste management and recycling industry, as they need to be handled and disposed of properly to mitigate environmental and health risks associated with lead exposure.

Production process

The production techniques for materials under HS code 262021 typically involve the collection, storage, and processing of various industrial waste streams. This may include the skimming of sludges from storage tanks, the separation of solid residues from liquid waste, and the stabilization or encapsulation of the lead-containing materials to reduce their hazardous properties.

Production inputs

The main inputs for this industry are the waste streams generated by other manufacturing processes, particularly those involving leaded fuels and additives. This includes waste from petroleum refineries, automotive repair shops, and other industrial facilities that handle or use leaded products. The industry also requires specialized equipment and facilities for the safe handling, transportation, and processing of these hazardous materials.

Production outputs

The primary outputs of this industry are stabilized or encapsulated lead-containing materials that can be safely disposed of or, in some cases, recycled and reused. These materials may be sent to 170401 Waste glass or 170402 Waste glass, other than from the production of glass, ceramic or enamelled products for further processing, or they may be sent to specialized hazardous waste disposal facilities. The industry also generates secondary outputs, such as recovered lead, that can be used as inputs for other industries, such as 780110 Unwrought lead; lead bullion.

Revisions to 262021

Classification codes are adjusted frequently. The code may have been revised or replaced between system versions. The table below shows the history (newest to oldest) of the code 262021. The most recent 1 version of this code (262021) is in the HS v2022 system:
