The U.S. Department of Commerce International Trade Administration has a relatively new online research tool for exporters and importers to use in looking up tariff rates from partners whom the U.S. has either entered into or is currently negotiating a free trade agreement with. I have reviewed the features of this new tool and find it extremely user friendly and helpful for tariff related research. Give it a try and let me know your feedback. The tool can be located at:
