About HS Code 251810
This code covers raw, unprocessed dolomite, a common carbonate mineral composed of calcium magnesium carbonate. In international trade, it's primarily exchanged as a bulk commodity for industrial applications. Major importers are typically countries with robust construction, steel, glass, and agricultural sectors that require this mineral as a raw material. Exporters are often nations with significant natural dolomite deposits and the infrastructure for quarrying and transportation. Key things to know include its use as an aggregate in concrete, a flux in metallurgy (especially steelmaking), a source of magnesium in agriculture (soil conditioner), and as a raw material for glass and ceramics. Its uncalcined state means it hasn't undergone high-temperature processing, distinguishing it from its calcined counterpart and making it suitable for applications where its chemical stability is preferred or further processing is done domestically. The trade volume is substantial, driven by global industrial demand.
Products Under This Code
Raw dolomite lumps, Crushed dolomite aggregate, Dolomite sand, Dolomite blocks, Dolomite slabs, Agricultural dolomite powder, Glass-grade dolomite
Real World Examples
Carmeuse Dolomite, Graymont Dolomite, R.W. Sidley Dolomite, US Aggregates Dolomite
Common Misclassification
This code is often confused with 251820 (calcined or sintered dolomite) because both are dolomite, but the key distinction is the processing state. It can also be confused with 252100 (limestone flux) if its primary use as a flux is emphasized, but dolomite has a distinct chemical composition.
Products Classified Under 2518.10
Industry
This code belongs to the Minerals & Fuels industry.
Trade Overview
Top importers include China, India, and Germany, while major exporters are Canada, the USA, and Turkey.
