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 3901.90.20

What is NCM 3901.90.20?

NCM 3901.90.20 (39019020) is the Brazilian (Mercosur) code for ethylene-carboxylic monomer copolymers. Its official Portuguese description is “Copolímeros de etileno e monômeros com radicais carboxílicos, inclusive com metacrilato de metila ou acrilato de metila como terceiro monômero”.

What is the HS code for NCM 3901.90.20?

HS 3901.90 (Ethylene polymers; in primary forms, n.e.c. in heading no. 3901). 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 3901.90.20?

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