Granulated Blast Furnace Slag (GBFS)
Granulated blast furnace slag is produced by rapidly quenching molten slag from iron production with water, resulting in glassy, granular particles known as slag sand. It falls under HTS 2618.00.00.00 as granulated slag specifically from iron or steel manufacture, used primarily as a supplementary cementitious material in concrete production.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used for metal extraction or chemical compounds
Chapter notes limit 2620 to slag for metal recovery or chemical manufacture, unlike cementitious uses.
If ground into Portland blast furnace slag cement
Processed into finished cement, it shifts to Chapter 25 under cement headings, not raw granulated slag.
If from municipal waste incineration
Chapter note excludes municipal waste ash from 2620 and places it in 2621, distinct from iron/steel slag.

Import Tips & Compliance
• Verify the slag originates from iron or steel manufacture via supplier certification to avoid misclassification as other wastes
• Ensure particle size and granulation meet 'slag sand' specs; test for metallic content per statistical notes
• Obtain environmental clearances as slag may be regulated for heavy metals; declare assay quantity accurately
