How to read NCM 3920.10.91

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.
