HS Code for Steel slag

Steel slag is classified under HS code 2619.00, which specifically covers slag, dross (other than granulated slag), scalings, and other waste resulting from the manufacture of iron or steel. This classification is determined by the material's origin as a byproduct of metallurgical processes. Unlike granulated slag, which is processed into a fine, glass-like substance for cement manufacturing, steel slag in this category typically consists of the stony waste separated from metals during smelting or refining. The classification follows the General Rules of Interpretation (GRI) 1, as the heading text explicitly names waste from iron or steel manufacture. It is essential to distinguish these materials from ores or concentrates, as they are secondary products rather than primary mineral sources. The physical state—whether in lumps, powder, or dust—is a primary factor in determining the correct subheading within Chapter 26. The material must be a byproduct of the iron and steel industry to qualify here; if it is a byproduct of non-ferrous metal extraction, it would be moved to heading 2620. Furthermore, the absence of granulation is the defining characteristic that separates 2619.00 from 2618.00.

Products Included

• Steel furnace slag
• Blast furnace dross
• Iron scale from rolling mills
• Smelting waste
• Steel scrap residues

Common Misclassification

Steel slag is frequently confused with HS code 2618.00, which is reserved exclusively for granulated slag (slag sand) from the manufacture of iron or steel. The distinction lies in the physical form; granulated slag is cooled rapidly with water or steam to create a glassy granule, whereas 2619.00 covers air-cooled or unprocessed slag. Additionally, if the slag contains significant amounts of other metals like lead, zinc, or copper, it may be classified under 2620.11 through 2620.99 depending on the predominant metal content.

FAQ

What is the HS code for steel slag?

The HS code for steel slag (non-granulated) is 2619.00.

Is granulated slag classified under the same code?

No, granulated slag is classified under HS code 2618.00 because it has undergone a specific cooling process to make it suitable for cement production.
