HS Code for Sulfuric acid

Sulfuric acid and oleum are classified under HS code 2807.00. This classification is part of Chapter 28 (Inorganic chemicals) and is a dedicated heading for one of the most significant industrial chemicals globally. Sulfuric acid (H2SO4) is classified here regardless of its concentration, provided it is not mixed with other chemicals in a way that changes its essential character to a prepared chemical product. Oleum, also known as fuming sulfuric acid, is a solution of sulfur trioxide in sulfuric acid and is included in this same heading because of its direct chemical relationship and shared industrial utility. The classification is straightforward because heading 2807 is a specific, non-split heading in many national tariffs, reflecting the commodity's status as a primary chemical building block used in fertilizers, mineral processing, and lead-acid batteries.

Products Included

• Concentrated sulfuric acid

• Oleum (fuming sulfuric acid)
• Chamber acid
• Contact acid

Common Misclassification

Sulfuric acid is sometimes misclassified under HS code 2806.10, which is for hydrogen chloride (hydrochloric acid), or HS code 2808.00, which covers nitric acid. These errors usually stem from administrative oversight in chemical inventory management. Additionally, spent sulfuric acid that is being returned for regeneration or disposal might be confused with waste chemicals in Chapter 38, but if it retains the characteristics of sulfuric acid, 2807.00 remains the primary classification.

FAQ

What is the HS code for sulfuric acid?

The HS code for sulfuric acid, including oleum, is 2807.00.

Does the HS code change for different concentrations of sulfuric acid?

No, whether it is highly concentrated 98% acid or diluted battery acid, it remains under HS code 2807.00 as long as it is a pure aqueous solution.
