The first 6 digits are the international HS code, so their meaning is the same in every country; Brazil publishes the text in Portuguese. The last two digits are 00 because Brazil does not split this HS code further. The full 8-digit code is used on import declarations (DUIMP), invoices (NF-e) and tax filings.

Questions about NCM 2903.46.00

What is NCM 2903.46.00?

NCM 2903.46.00 (29034600) is the Brazilian (Mercosur) code for fluoropropanes HFC-227ea, -236cb, -236ea, -236fa. Its official Portuguese description is “1,1,1,2,3,3,3-Heptafluoropropano (HFC-227ea), 1,1,1,2,2,3-hexafluoropropano (HFC-236cb), 1,1,1,2,3,3-hexafluoropropano (HFC-236ea) e 1,1,1,3,3,3-hexafluoropropano (HFC-236fa)”.

What is the HS code for NCM 2903.46.00?

HS 2903.46 (Saturated fluorinated derivatives of acyclic hydrocarbons; 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea), 1,1,1,2,2,3-hexafluoropropane (HFC-236cb), 1,1,1,2,3,3-hexafluoropropane (HFC-236ea) and 1,1,1,3,3,3-hexafluoropropane (HFC-236fa)). 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 2903.46.00?
