Macadam of slag, dross or similar industrial waste; whether or not incorporating the materials in item no. 2517.10

HS v2017 Code: 251720

About macadam of slag, dross or similar industrial waste; whether or not incorporating the materials in item no. 2517.10

HS code 251720 covers macadam, a type of road surfacing material made from slag, dross, or other industrial waste. 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, reducing waste, and minimizing the environmental impact of construction activities.

Production process

The production of macadam under HS code 251720 typically involves crushing, screening, and processing slag, dross, or other industrial waste materials. These materials are then combined and compacted to create a durable, load-bearing surface suitable for use in roads, pathways, and other construction applications.

Production inputs

The main inputs for the production of macadam under HS code 251720 include slag, dross, and other industrial waste materials. Specialized machinery, such as crushers, screens, and compactors, are also essential for the processing and shaping of these materials. Additionally, binders or additives may be used to enhance the performance and durability of the final macadam product.

Production outputs

The primary output of the industry covered by HS code 251720 is macadam, a versatile construction material used in a variety of applications. Macadam is commonly used in the construction and maintenance of roads, highways, and other transportation infrastructure. It may also be used in the production of 251710 Pebbles, gravel, broken or crushed stone, of a kind commonly used for concrete aggregates, for road metalling or for railway or other ballast, shingle and flint, whether or not heat-treated, 251720 Macadam of slag, dross or similar industrial waste, whether or not incorporating the materials cited in subheading 2517.10, and 251730 Tarred macadam.
