Native Lump Sulfur
Large irregular lumps of elemental sulfur mined from caprock deposits, unrefined and suitable for crushing. The lumps are in a crude state with no processing beyond mining, and they are not sublimed, precipitated, or colloidal, so they fall under 2503.00.00.

Bolivian Huari Huari Sulfur
High-purity native sulfur from the Huari Huari mine in Bolivia, hand-collected from high-altitude lagoons. The sulfur is in a crude state with minimal processing, and it is not sublimed, precipitated, or colloidal, so it is classifiable under 2503.00.00.
Bulk Crushed Sulfur Rock
Bulk crushed sulfur rock, mined and crushed from native sulfur deposits, used directly in sulfuric acid production. The crushing process is a permitted mechanical treatment under Chapter 25 Note 1, and the product is not sublimed, precipitated, or colloidal sulfur, so it falls under tariff item 2503.00.00.
Bulk Lump Sulfur from Mines
Irregular lumps of native sulfur mined from surface outcrops, typically 99% pure with rock inclusions. This crude form of sulfur has not been sublimed, precipitated, or subjected to any processing beyond washing or crushing, and therefore falls under tariff item 2503.00.00.
Caprock Native Sulfur
Native sulfur extracted from limestone caprock formations above salt domes, mined via conventional methods. This crude sulfur is not sublimed or precipitated and is classified under tariff item 2503.00.00 as other non-sublimed, non-precipitated sulfur.
Crude Native Sulfur Ore
Raw sulfur extracted from natural volcanic deposits or caprock formations, containing impurities like dirt and moisture. This unrefined sulfur of natural origin is not sublimed or precipitated, and is classified under tariff item 2503.00.00.
Crude Natural Sulfur Ore
Crude natural sulfur ore extracted from volcanic or underground deposits, containing impurities like soil and moisture. It is in a crude state with no processing beyond washing or mechanical separation, consistent with Chapter 25 Note 1, and is not an excluded form, so it is classifiable under 2503.00.00.
