HS 2931.59 (Halogenated organo-phosphorous derivatives; other halogenated organo-phosphorous derivatives, n.e.c. in item no. 2931.5). 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.
