Sulfur (Crude, Refined, and Other — Excluding Sublimed, Precipitated, and Colloidal)

U.S. imports of sulfur (crude, refined, and other — excluding sublimed, precipitated, and colloidal) (HS 250300) totaled $78.3M in April 2026, traded with 11 countries.

Last updated: April 2026 data

Recovered as a byproduct of petroleum refining and natural gas processing, bulk sulfur in crude or refined form is one of the most widely traded industrial minerals, serving as the primary feedstock for sulfuric acid and fertilizer manufacturing. The US schedule divides this heading into crude/unrefined sulfur (2503000010) and refined sulfur (2503000090), with the processing grade determining classification. Canada is the dominant supplier, reflecting the proximity of Alberta's oil sands operations, with the United Arab Emirates and India also significant sources. Sublimed, precipitated, and colloidal sulfur forms are explicitly excluded and classified elsewhere.

Frequently Asked Questions

What distinguishes crude sulfur from refined sulfur for HTS classification under this heading?

Crude or unrefined sulfur (2503000010) is the raw, minimally processed form typically recovered directly from gas or petroleum streams. Refined sulfur (2503000090) has undergone further purification. Both exclude sublimed, precipitated, and colloidal forms, which are classified under different headings.

What countries account for the largest share of US sulfur imports under this heading?

Canada is by far the leading supplier, driven by its large petroleum and natural gas sector. The United Arab Emirates and India are also notable sources, followed by Italy and China.
