Last updated: August 2026 dataCrude and refined elemental sulfur — the bulk commodity recovered from petroleum refining and natural gas processing — is the dominant product under this heading, with the US schedule separating crude/unrefined (2503000010) from refined sulfur (2503000090). Sulfur is a primary input for sulfuric acid, fertilizers (superphosphates), and rubber vulcanization, making it a high-volume industrial mineral. Canada is by far the largest US import source, driven by Alberta's oil sands and natural gas operations that generate large volumes of recovered sulfur as a byproduct.

Crude or unrefined sulfur (2503000010) is typically recovered directly from petroleum or gas processing with minimal further treatment — it may contain impurities and is often shipped in molten or granular form for industrial use. Refined sulfur (2503000090) has undergone additional purification to meet higher purity specifications required for certain chemical or agricultural applications. The distinction is based on the degree of processing and purity, and importers should obtain mill certificates or supplier specifications to support the correct line selection.
No. The heading explicitly excludes sublimed sulfur, precipitated sulfur, and colloidal sulfur — those forms are classified in Chapter 28 as inorganic chemicals. This heading covers only bulk elemental sulfur in its crude, refined, or other non-sublimed/non-precipitated forms. Importers dealing in pharmaceutical-grade or finely processed sulfur should confirm the correct chapter with a customs broker.
