Unfortunately not. There is a thing called The Tariff, a document that explains exactly what you need to pay (as an individual or as a company).

Some also need to pay VAT, some don't.
It's pretty hard to figure out.

Food items are generally 0% duty 0% vat, but it depends exactly what they are and where they are imported from.
