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 2844.43.30

What is NCM 2844.43.30?

NCM 2844.43.30 (28444330) is the Brazilian (Mercosur) code for iodine-131 radioactive isotope. Its official Portuguese description is “Iodo-131”.

What is the HS code for NCM 2844.43.30?

HS 2844.43 (Radioactive elements, isotopes and compounds; other alloys, dispersions (including cermets), ceramic products and mixtures containing these elements, isotopes or compounds). 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 2844.43.30?

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