Related Products under Tariff item 2520.10.00
Agricultural Gypsum Pellets
Agricultural gypsum pellets made from natural, uncalcined gypsum for soil pH adjustment and sulfur supplementation. The pelleting process is mechanical and does not alter the chemical structure, keeping it within the scope of this heading.
Anhydrite Mineral
Natural anhydrite mineral, a calcium sulfate without water of crystallization, mined as rock or powder. It is explicitly listed in the tariff item alongside gypsum and is not subjected to calcination or other chemical processing.
Blue Diamond Gypsum
High-grade gypsum ore from Blue Diamond Mines, Nevada, unprocessed and shipped in bulk for wallboard manufacturing. As crude gypsum, it falls under this tariff item, which covers products in the crude state or after limited mechanical processing.
Calcined-Free Gypsum Aggregate
Crushed gypsum aggregate for concrete admixture, verified non-calcined and used to improve workability. The crushing process is mechanical and does not change the product's structure, so it remains classified as crude gypsum under this item.
Construction Grade Gypsum
High-purity gypsum lumps selected for wallboard manufacturing, in crude form before calcining. This tariff item covers gypsum in the crude state or after mechanical processing such as crushing, but not calcined products.
Dentstone Gypsum Rock
Specialty gypsum ore for dental stone production, selected for uniform crystals and high strength. As uncalcined gypsum, it falls under this item; calcination into alpha hemihydrate would change its classification.
