U.S. exports of Sublimed, Precipitated, and Colloidal Sulfur (HS 280200) totaled $132K in August 2026.
Importers of Sublimed, Precipitated, and Colloidal Sulfur paid $1K in duties in August 2026, an average duty rate of 1.24% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Sublimed, Precipitated, and Colloidal Sulfur imports of $107K in August 2026 ran 82% below the year-to-date monthly average of $587K.
Last updated: August 2026 dataProcessed through sublimation or precipitation to achieve fine particle size and high purity, these specialty sulfur forms (classified under 2802000000) are distinct from crude or recovered sulfur and serve niche applications in agriculture (fungicides and soil amendments), rubber vulcanization, and pharmaceutical manufacturing. Japan and China are the leading sources for US imports of this heading. The processing method — sublimed versus precipitated versus colloidal — determines particle size and surface area, which are critical specification parameters that buyers should confirm against technical data sheets.

Sublimed sulfur (flowers of sulfur) is produced by vapor condensation and has a relatively coarse particle size; precipitated sulfur (milk of sulfur) is chemically deposited and finer; colloidal sulfur is an ultrafine suspension. All three fall under 2802000000, but their particle-size and purity differences make them non-interchangeable in applications such as agricultural fungicides or rubber compounding — buyers should specify the form explicitly in purchase contracts.
Sulfur-based fungicides registered under FIFRA are regulated by the EPA, but elemental sulfur imported in bulk as a chemical intermediate (rather than as a formulated pesticide product) generally enters under standard CBP procedures. If the imported material is a formulated pesticide product, EPA registration and labeling requirements apply. Consult a licensed customs broker or regulatory counsel to confirm the correct entry pathway for your specific product.
