Product classification
HS code for Sulfuric acid: 2807.00
Sulphuric acid, oleum.
Classification of sulfuric acid under HS 2807.00
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.

Codes often confused with 2807.00
Common mistake. 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.
Top exporters and importers of HS 280700 (the code used for sulfuric acid), 2025
In 2025, the largest exporter of HS 280700 (the code used for sulfuric acid) in UN Comtrade data was China, with 14% of world exports; the largest importer in UN Comtrade data was Chile, with 19% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
