Methodology
What the numbers are, where they come from, and what they do not include.
Where the data comes from
Every figure on this site is built from Comex Stat, the Brazilian Ministry of Development, Industry, Trade and Services (MDIC) system that publishes the country's import and export declarations. We use the official monthly CSV files for 1997 to 2021 and the official API for 2022 onwards. Nothing is scraped from private sources and nothing is estimated.
What is measured
Imports are recorded by 8-digit NCM code, origin country and month. Values are declared FOB in US dollars, as published by MDIC. We do not convert historical values to reais, because exchange rate choices would change the comparison and hide the original figure.
What is not included
Brazilian law keeps company-level customs information confidential. Comex Stat contains no company names, no CNPJs, no importer identities and no bills of lading, and neither do we. Anyone selling "official Brazilian importer records" is either using a private maritime manifest feed or misrepresenting the source.
Duties and landed cost
Import duty (II) comes from the TEC tariff table, IPI from TIPI. PIS/COFINS is applied at 11.75% on CIF, and state ICMS is grossed up at the destination state's rate. Ex-tarifario reductions and state ICMS benefits are not applied, and the estimate excludes SISCOMEX, AFRMM, freight and insurance unless you enter them. Where a code has no published rate, the chapter median is used and the response flags it.
Code revisions
The NCM has been revised several times since 1997. Codes retired in earlier revisions remain in the history under their original number. A long series for one code can therefore mix natures across revisions. Compare within a revision when precision matters.
Refresh and corrections
The dataset is refreshed monthly when MDIC publishes. Last data month: October 2026. Found something that looks wrong? Write to [email protected] with the code and period.
