About HS Code 251820
This HS code encompasses dolomite that has undergone calcination or sintering, processes involving high-temperature treatment to alter its chemical and physical properties. This processed form, often referred to as "dolime" or "sintered dolomite," is a crucial commodity in global trade, valued for its enhanced reactivity and specific industrial applications. Countries with advanced metallurgical industries, particularly steel production, are significant importers, as calcined dolomite serves as a refractory material and a flux. It's also vital for environmental applications like water treatment and flue gas desulfurization. Exporters are typically nations with abundant raw dolomite reserves and the energy-intensive facilities required for calcination. The trade involves specialized bulk carriers and careful handling due to its reactivity. Understanding the degree of calcination is important, as it impacts the material's properties and suitability for different end-uses, making it distinct from raw dolomite.
Products Under This Code
Calcined dolomite, Sintered dolomite, Dolime, Refractory-grade calcined dolomite, Metallurgical dolime, Agricultural dolime, Water treatment dolime
Real World Examples
RHI Magnesita Dolime, Vesuvius Refractories Dolime, Lhoist Dolime, Carmeuse Dolime
Common Misclassification
This code is frequently confused with 251810 (dolomite, not calcined or sintered) due to the shared base material; the distinction lies solely in the thermal processing. It might also be mistaken for certain magnesium oxides under 251990 if the magnesium content is the primary focus, but 251820 specifically refers to calcined dolomite.
Products Classified Under 2518.20
Industry
This code belongs to the Minerals & Fuels industry.
Trade Overview
Key importers include Japan, South Korea, and Germany, with major exporters being China, Brazil, and the USA.
