About HS Code 290431
This specific HS code targets Perfluorooctane Sulphonic Acid (PFOS), a synthetic fluorinated compound known for its surfactant properties and chemical stability. PFOS and its derivatives have been widely used in various industrial and consumer products due to their water and oil repellent characteristics. Historically, it was a key ingredient in fire-fighting foams, metal plating, textiles, paper coatings, and photographic materials. However, due to its persistence in the environment, bioaccumulation, and potential toxicity, PFOS is now largely restricted or banned under international agreements like the Stockholm Convention. Trade in PFOS is highly regulated, with most countries phasing out its production and use. Importers might include specialized industries with specific exemptions for critical applications, or those involved in remediation efforts. Exporters are typically chemical companies in countries that previously manufactured PFOS, now managing existing stocks or producing for very limited, approved uses. Key things to know are the stringent international regulations, the need for proper documentation for any permitted trade, and the ongoing global efforts to find safer alternatives.
Products Under This Code
Perfluorooctane sulfonic acid (PFOS), Potassium perfluorooctane sulfonate, Ammonium perfluorooctane sulfonate, Lithium perfluorooctane sulfonate, PFOS-based fire fighting foam concentrates, PFOS-containing textile treatments
Real World Examples
3M (historical producer of PFOS, now phased out), Chemours (fluorochemicals, but PFOS largely restricted), Daikin (fluorochemicals, but PFOS largely restricted)
Common Misclassification
Can be confused with other per- and polyfluoroalkyl substances (PFAS) under different HS codes, such as PFOA (Perfluorooctanoic acid) or its salts, which fall under other specific subheadings or broader organic fluorine compounds (e.g., 2903).
Products Classified Under 2904.31
Industry
This code belongs to the Chemicals industry.
Trade Overview
Trade is highly restricted globally, with limited imports/exports primarily for specific exempted uses or existing stock management, often involving countries like China, USA, and EU member states under strict regulations.
Frequently Asked Questions
What is HS code 290431?
HS code 290431 covers: Derivatives of hydrocarbons; perfluorooctane sulphonic acid, whether or not halogenated.

What products fall under HS code 290431?
Perfluorooctane sulfonic acid (PFOS), Potassium perfluorooctane sulfonate, Ammonium perfluorooctane sulfonate, Lithium perfluorooctane sulfonate, PFOS-based fire fighting foam concentrates, PFOS-containing textile treatments
What are common misclassifications for HS code 290431?
Can be confused with other per- and polyfluoroalkyl substances (PFAS) under different HS codes, such as PFOA (Perfluorooctanoic acid) or its salts, which fall under other specific subheadings or broader organic fluorine compounds (e.g., 2903).
How is HS code 290431 structured?
HS code 290431 is a 6-digit subheading under the Harmonized System. The first 2 digits (29) identify the chapter, digits 3-4 (04) identify the heading, and digits 5-6 (31) specify the subheading. This code is standardized globally by the World Customs Organization.
