HS Code for Colloidal sulphur

Colloidal sulphur is classified under HS code 2802.00. This heading is unique because it specifically enumerates three distinct forms of sulphur: sublimed, precipitated, and colloidal. Chapter 28 covers inorganic chemicals, and heading 2802 is the dedicated provision for these refined or specially processed forms of sulphur. Colloidal sulphur is typically prepared by the action of an acid on a solution of a thiosulphate or by mechanical grinding in the presence of protective colloids. This results in a product where the sulphur particles are so fine that they remain in suspension. The classification is straightforward because the Harmonized System provides a specific heading that names the product, satisfying GRI 1. This heading excludes crude sulphur, which is classified in Chapter 25.

Products Included

• Milk of sulphur (precipitated sulphur)
• Flowers of sulphur (sublimed sulphur)
• Colloidal sulphur suspensions
• Refined sulphur for laboratory use

Common Misclassification

The most common misclassification for colloidal sulphur is HS code 2503.00, which covers sulphur of all kinds, other than sublimed, precipitated, and colloidal sulphur. Importers often default to Chapter 25 for mineral products, but the specific processing required to create colloidal sulphur moves it into Chapter 28. Additionally, if colloidal sulphur is prepared as a fungicide for retail sale, it may be misclassified under HS code 3808.92. However, if it is pure colloidal sulphur without added surfactants or carriers for agricultural use, 2802.00 remains the correct code.
