Questions about NCM 8533.39.10

What is NCM 8533.39.10?

NCM 8533.39.10 (85333910) is the Brazilian (Mercosur) code for wirewound potentiometers, over 20 W. Its official Portuguese description is “Potenciômetros”.

What is the HS code for NCM 8533.39.10?

HS 8533.39 (Electrical resistors; wirewound variable, including rheostats and potentiometers, for a power handling capacity exceeding 20W (excluding heating)). 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 8533.39.10?

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