Frequently Asked Trade News Questions

How often do import tariff rates change?

Tariffs can change during annual budget announcements, presidential trade decrees, or bilateral trade treaty adjustments. We update our databases monthly to reflect updates.

What is the difference between ad-valorem and specific duties?

Ad-valorem duties are percentages of the transaction value. Specific duties are fixed monetary charges per physical unit (like weight or count) of the cargo.

How do anti-dumping duties protect local markets?

Anti-dumping duties are steep protective surcharges imposed on imports priced below fair market values, neutralizing foreign subsidization.
