HS Code for Granulated Slag: 2025 Complete Guide
TL;DR
HS code 2618.00 covers granulated slag from iron/steel production, key for sustainable construction trade. This 2025 guide details classification, updates, challenges, and shipping tips for importers/exporters worldwide.
What is the HS Code for Granulated Slag?
Granulated slag falls under HS code 2618.00 in the Harmonized System. This 6-digit code classifies "granulated slag (slag sand) from the manufacture of iron or steel" under Chapter 26: Ores, slag, and ash.
Exporters and importers use this HS code for customs declarations, tariffs, and trade statistics globally.
Granulated Slag Definition and Properties
Granulated slag is a glassy, granular byproduct from rapidly cooling molten blast furnace slag. It serves as a cement replacement in concrete, boosting sustainability.
- High silica and alumina content for pozzolanic reactions
- Density: 2.8–2.9 g/cm³, ideal for concrete mixes
- Particle size: Typically 0–4.75 mm (fine aggregate)
- Low water demand, improving workability
- Reduces alkali-silica reaction risks in concrete
Why HS Code 2618.00 Matters in International Trade
Accurate HS code classification ensures compliance and avoids delays in granulated slag shipments. The World Customs Organization (WCO) maintains HS as the global standard.
- Determines import/export duties and taxes
- Tracks trade volumes for market analysis
- Enables proper dangerous goods handling if applicable
- Supports quota and license requirements
- Facilitates origin rules in FTAs
