Macadam of slag, dross or similar industrial waste; whether or not incorporating the materials in Tariff item 2517.10.00

HS v2022 Code: 251720

About macadam of slag, dross or similar industrial waste; whether or not incorporating the materials in tariff item 2517.10.00

HS code 251720 covers macadam, a type of road surfacing material made from slag, dross, or other industrial waste products. This industry plays a crucial role in the construction and infrastructure sectors, providing a cost-effective and sustainable alternative to traditional aggregates. The production and use of macadam contribute to the circular economy by repurposing industrial byproducts that would otherwise be discarded.

Production process

The production of macadam under HS code 251720 typically involves crushing, screening, and processing slag, dross, or other industrial waste materials. These raw materials are carefully selected and blended to meet specific quality and performance requirements. The crushed and graded materials are then compacted and bound together to create a durable, long-lasting surface for roads, pathways, and other infrastructure applications.

Production inputs

The main inputs for the production of macadam under HS code 251720 are slag, dross, and other industrial waste materials. These byproducts are sourced from various manufacturing and processing industries, such as 720110 iron and steel production, 281410 inorganic chemical production, and 252100 lime and cement production. In addition to the raw materials, the industry also requires specialized machinery and equipment for crushing, screening, and compacting the macadam.

Production outputs

The primary output of the industry covered by HS code 251720 is macadam, a type of road surfacing material. This macadam can be used in the construction and maintenance of roads, highways, and other transportation infrastructure. The output of this industry may also be consumed by industries related to 680100 building and construction, 680200 prefabricated buildings, and 680500 other articles of stone, plaster, cement, asbestos, mica or similar materials.
