I would like to know where I can find some data of export and import by products of the Harmonized System or any other system (code).
I need a site that has at least 40 years of the value of exports and imports by country (world too) and by products (most disaggregate level) .
I have tried with comtrade, IMF, and WTO. But, I have not found those values.
I really apprecciatte If someone can send me a link.
Sincerely,
José Tomás
