What is the HS code for NCM 2836.99.11?

HS 2836.99 (Carbonates; n.e.c. in heading no. 2836 and other than lithium or strontium). The first 6 digits of an NCM code are its international HS code; the last 2 digits are Brazil's own split.

Is an NCM code the same as an HS code?

The first 6 digits are the same in every country. NCM adds an item digit (7th) and a subitem digit (8th). A code ending in 00 means Brazil does not split that HS code further.

Which countries use NCM 2836.99.11?

All Mercosur members use the same NCM codes: Argentina, Brazil, Paraguay and Uruguay.
