Product classification
HS code for Barium sulphate: 2833.27
Sulphates, of barium.
Classification of barium sulphate under HS 2833.27
Barium sulphate, when in its manufactured or synthetic form, is classified under HS code 283327. This classification falls within Chapter 28 of the Harmonized System, which covers inorganic chemicals, organic or inorganic compounds of precious metals, of rare-earth metals, of radioactive elements or of isotopes. Specifically, heading 2833 pertains to sulphates, alums, and peroxosulphates (persulphates). The subheading 283327 is designated for "Sulphates; of barium," clearly identifying the chemical compound. This classification is crucial for distinguishing synthetic barium sulphate from its naturally occurring mineral form, barytes, which is classified elsewhere due to its origin and minimal processing.

- Baroid (drilling fluid additive)
Codes often confused with 2833.27
Common mistake. A common misclassification occurs with natural barium sulphate, known as barytes, which is classified under HS code 251110. The distinction lies in the origin and processing: 283327 is for chemically manufactured or synthetic barium sulphate, while 251110 is for the natural mineral form, even if it has undergone crushing or grinding. Another potential confusion could be with other sulphates of metals, which fall under codes like 283329 (other sulphates of metals), but the specific chemical identity of barium sulphate directs it to 283327.
Top exporters and importers of HS 283327 (the code used for barium sulphate), 2025
In 2025, the largest exporter of HS 283327 (the code used for barium sulphate) in UN Comtrade data was China, with 70% of world exports; the largest importer in UN Comtrade data was India, with 14% 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 that did not report are estimated from what other countries recorded trading with them. 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).

How do I classify Barium sulphate for customs?
Barium sulphate is classified under HS code 283327 — Sulphates; of barium. This is a 6-digit subheading level code.
What is the difference between synthetic barium sulphate and barytes for HS classification?
Synthetic barium sulphate (283327) is a chemically manufactured product, whereas barytes (251110) is the natural mineral form of barium sulphate, even after physical processing like grinding.
Which countries are the top exporters of barium sulphate (HS 283327)?
In 2025, the top exporters of HS 283327 (the code used for barium sulphate) in UN Comtrade data were China ($54M, 70% of world exports), Japan ($10M) and the United States ($4.6M). World exports came to about $77M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of barium sulphate (HS 283327)?
