U.S. imports of Sulfur (Excluding Sublimed, Precipitated & Colloidal Forms) (SITC 27410) totaled $92.1M in September 2026, imported from 16 countries.
Importers of Sulfur (Excluding Sublimed, Precipitated & Colloidal Forms) paid $13K in duties in September 2026, an average duty rate of 0.01% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Sulfur (Excluding Sublimed, Precipitated & Colloidal Forms) imports of $92.1M in September 2026 ran 32% above the year-to-date monthly average of $69.9M.
Last updated: September 2026 dataCrude and refined elemental sulfur — recovered primarily as a byproduct of petroleum refining and natural gas processing — is a foundational chemical feedstock for sulfuric acid production, fertilizer manufacturing (particularly phosphate fertilizers), and rubber vulcanization. Sublimed, precipitated, and colloidal sulfur are explicitly excluded from this heading, which covers the bulk commercial grades most relevant to agricultural and industrial supply chains. The US is both a significant producer and importer of elemental sulfur, with trade flows driven by refinery output cycles and fertilizer demand seasonality.

Sublimed sulfur (flowers of sulfur), precipitated sulfur, and colloidal sulfur are excluded from SITC 27410. These refined forms are used in pharmaceuticals, agriculture (fungicides), and specialty chemicals, and are classified under separate chemical headings. The distinction matters because duty treatment and end-use documentation requirements may differ.
Sulfur is a key input for phosphoric acid and phosphate fertilizer production. Import demand typically rises ahead of spring and fall fertilizer application seasons, when sulfuric acid plants ramp up production. Importers and traders often build inventory in the preceding months, making Q4 and Q1 active periods for sulfur trade logistics.
