The first 6 digits are the international HS code, so their meaning is the same in every country; Brazil publishes the text in Portuguese. Digits 7 and 8 are Brazil's own split of that HS code. The full 8-digit code is used on import declarations (DUIMP), invoices (NF-e) and tax filings.

Questions about NCM 2930.90.84

What is NCM 2930.90.84?

NCM 2930.90.84 (29309084) is the Brazilian (Mercosur) code for 1,2-Bis(2-chloroethylthio)ethane. Its official Portuguese description is “1,2-Bis(2-cloroetiltio)etano”.

What is the HS code for NCM 2930.90.84?

HS 2930.90 (Organo-sulphur compounds; n.e.c. in heading no. 2930). 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 2930.90.84?

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