HTS Code: 2618 — Granulated Slag from Iron or Steel Manufacture

This classification pertains to granulated slag, also referred to as slag sand, which is a granular material formed as a byproduct during the manufacturing of iron and steel. This material is generated when molten slag is rapidly cooled, producing a glassy, granular substance that has various industrial applications.

Granulated slag is commonly utilized in the construction industry, cement production, and as an aggregate in concrete, owing to its hydraulic cementitious properties. It serves as an environmentally friendly alternative to Portland cement by enhancing concrete durability and reducing greenhouse gas emissions.

Code Hierarchy

• Section V:
• Mineral Products (Chapters 25-27)
• Chapter 26: Ores, Slag and Ash
• Heading 2618: Granulated slag (slag sand) from the manufacture of iron or steel.
• US HTS Code (10-digit): 2618.00.00.00 – The full classification for granulated slag without further subdivision under this heading.

Detailed Breakdown of Subheadings

The heading 2618 currently has a single recognized 10-digit code specifying granulated slag from iron or steel production:

What is NOT Classified Here?

To ensure correct classification, the following are excluded:

• Other types of slag such as air-cooled slag or pelletized slag are classified under different headings.
• Iron ore, iron ore concentrates or other mineral ores are classified under Chapter 26 but different headings than 2618.
• Blast furnace slag in forms other than granulated or slag sand are not included here.
• Slag residues intended for metal recovery may be classified elsewhere depending on composition and use.

Notes

• Industrial Use:
• The granulated slag covered by this code is valued for its cementitious properties and environmental benefits in construction.
• Import/Export Considerations: Tariff rates for this heading vary by country and trade agreements; always verify current duty rates.
• Environmental Impact: Using granulated slag reduces reliance on natural resources and lowers carbon emissions associated with cement production.
