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 2903.77.31

What is NCM 2903.77.31?

NCM 2903.77.31 (29037731) is the Brazilian (Mercosur) code for heptachlorofluoropropanes (CFC-211). Its official Portuguese description is “Heptaclorofluoropropanos”.

What is the HS code for NCM 2903.77.31?

HS 2903.77 (Halogenated derivatives of acyclic hydrocarbons containing two or more different halogens; n.e.c. in headings 290371 to 290376, perhalogenated only with fluorine and chlorine). 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 2903.77.31?

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