Product classification
HS code for Barium carbonate: 2836.99
Carbonates, n.e.c. in heading no. 2836 and other than lithium or strontium.
Classification of barium carbonate under HS 2836.99
Barium carbonate is classified under Harmonized System (HS) code 283699. This classification falls within Chapter 28, which covers "Inorganic chemicals; organic or inorganic compounds of precious metals, of rare-earth metals, of radioactive elements or of isotopes." Specifically, heading 2836 is dedicated to "Carbonates; peroxocarbonates (percarbonates); commercial ammonium carbonate containing ammonium carbamate." Barium carbonate is an inorganic carbonate. Since it is not specifically enumerated in the more precise subheadings under 2836, such as those for lithium carbonates (283691) or strontium carbonate (283692), it falls into the residual category 283699, which covers "Other carbonates." This ensures that all carbonates not explicitly listed elsewhere within the heading are appropriately classified.

Codes often confused with 2836.99
Common mistake. Barium carbonate can sometimes be confused with other inorganic compounds. For example, HS 283620 covers "Sodium carbonate," which is a distinct chemical. While both are carbonates, their specific chemical compositions differ. Another potential misclassification might be with HS 283660, which covers "Barium sulfate." Although both compounds contain barium, their anionic components (carbonate vs. sulfate) are chemically distinct, leading to different classifications. Furthermore, it is important not to confuse it with the specific codes for other carbonates like HS 283691 (Lithium carbonates) or HS 283692 (Strontium carbonate), as these are explicitly excluded from the "other" category of 283699.
Top exporters and importers of HS 283699 (the code used for barium carbonate), 2025
In 2025, the largest exporter of HS 283699 (the code used for barium carbonate) in UN Comtrade data was China, with 31% of world exports; the largest importer in UN Comtrade data was the United States, with 12% of world imports. The United Kingdom reports $2.7B of its chapter 28 imports without product detail (confidential), so it may also belong among the top importers.

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).

Questions about barium carbonate
What is the HS code for Barium carbonate?
The HS code for Barium carbonate is 283699 (Carbonates; n.e.c. in heading no. 2836 and other than lithium or strontium). The HS code for Barium carbonate is 283699.
How do I classify Barium carbonate for customs?
Barium carbonate is classified under HS code 283699 — Carbonates; n.e.c. in heading no. 2836 and other than lithium or strontium. This is a 6-digit subheading level code.
Why is barium carbonate not listed under a more specific HS code?
Barium carbonate is classified under 283699 because it is an inorganic carbonate that is not specifically enumerated in other, more precise subheadings of 2836, such as those dedicated to lithium or strontium carbonates. The 283699 subheading serves as a residual category for all other carbonates not specified elsewhere within heading 2836.
Which countries are the top exporters of barium carbonate (HS 283699)?
In 2025, the top exporters of HS 283699 (the code used for barium carbonate) in UN Comtrade data were China ($304M, 31% of world exports), Germany ($216M) and Poland ($101M). World exports came to about $984M, 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 carbonate (HS 283699)?
In 2025, the top importers of HS 283699 (the code used for barium carbonate) in UN Comtrade data were the United States ($121M, 12% of world imports), Malaysia ($86M) and India ($49M). World imports came to about $1.0B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). The United Kingdom reports $2.7B of its chapter 28 imports without product detail (confidential), so it may also belong among the top importers.
Is the HS code for Barium carbonate the same in all countries?
The base HS code 283699 for Barium carbonate is internationally standardized for the first 6 digits across 200+ countries. Individual countries may add additional digits for national tariff lines and specific classifications.
What is the NCM code for barium carbonate in Brazil?
Brazil splits HS 283699 into 5 NCM codes, so the right one for barium carbonate depends on the product's details: 2836.99.11 (Magnesium carbonate, density under 200 kg/m³), 2836.99.12 (Zirconium carbonate), 2836.99.13 (Commercial and other ammonium carbonates), 2836.99.19 (Other carbonates), 2836.99.20 (Peroxocarbonates (percarbonates)).
