Heading 2836 covers carbonates; peroxocarbonates (percarbonates); commercial ammonium carbonate containing ammonium carbamate. It splits into 2 six-digit subheadings and 2 US tariff lines, 0 of which are duty-free under the general rate.
Headings are the four-digit level of the Harmonized System — the layer that is identical across all 160-plus countries that use it. The six-digit subheading is also international; the last two digits of each code here are US-specific and do not carry across to another country's tariff.
