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 8541.21.91

What is NCM 8541.21.91?

NCM 8541.21.91 (85412191) is the Brazilian (Mercosur) code for heterojunction FETs (HJFET, HEMT) under 1 W. Its official Portuguese description is “De efeito de campo, com junção heterogênea (HJFET ou HEMT)”.

What is the HS code for NCM 8541.21.91?

HS 8541.21 (Electrical apparatus; transistors, (other than photosensitive), with a dissipation rate of less than 1W). 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 8541.21.91?

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