Tarred macadam

HS v2017 Code: 251730

About tarred macadam

HS code 251730 covers tarred macadam, a type of road surfacing material that has been widely used in construction and infrastructure projects around the world. Tarred macadam is a mixture of graded aggregates, such as crushed stone or gravel, bound together with a bituminous binder, typically tar or asphalt. This durable and weather-resistant material plays a crucial role in the development and maintenance of transportation networks, contributing to the smooth and efficient movement of goods and people across the global economy.

Production process

The production of tarred macadam involves several key steps. First, the aggregates are carefully selected, crushed, and graded to the desired size specifications. The bituminous binder, such as tar or asphalt, is then heated and mixed with the aggregates, creating a homogeneous mixture. This mixture is then laid and compacted on the desired surface, forming a smooth and resilient road surface that can withstand heavy traffic and environmental conditions.

Production inputs

The main inputs required for the production of tarred macadam include crushed stone or gravel, bituminous binders (such as tar or asphalt), and specialized equipment for mixing, transporting, and laying the material. The quality and consistency of the aggregates and binders are critical to ensuring the durability and performance of the final product. Additionally, the production process may require energy sources, such as fuel for heating the binders, and skilled labor to operate the equipment and ensure proper installation.

Production outputs

Tarred macadam, produced under HS code 251730, is primarily used as a surfacing material for roads, highways, and other transportation infrastructure. Its output is often consumed by 230690 (Bituminous mixtures based on natural asphalt, on natural bitumen, on petroleum bitumen, on mineral tar or on mineral tar pitch (excl. mastic asphalt)) and 680800 Panels, boards, tiles, blocks and similar articles of vegetable fibre, of straw or of shavings, chips, particles, sawdust or other waste of wood, agglomerated with cement, plaster or other mineral binders.
