The CSL Globe® US Tariff Search Engine uses official tariff data from the U.S. International Trade Commission (USITC). It shows the product description, base duty rate and any extra U.S. tariffs that may apply.
Search by product name or tariff code, choose any country or region of origin, and set the planned entry date. You can verify the source directly on the USITC website.
We update the tool when the U.S. government publishes a new tariff schedule or policy change, so each search uses the latest available rules.
In October 2026, the tool was updated with the tariff schedule published on October 9. That update included a change to an exclusion from the U.S. tariffs on Chinese goods.
The HTS line is the starting point. These programs can add duties, change the rate or require importer-specific evidence.
Additional duties apply to covered goods and can change by product list, exclusion and effective date. Check the underlying HTS Chapter 99 heading against the article and origin.
National-security measures cover selected steel, aluminum, copper, vehicles and derivative products. Product scope and non-U.S. content can affect the applicable duty.
Country measures can sit outside the ordinary HTS line and may stack with Section 301 or Section 232. The entry date and product exclusions must be checked together.
Antidumping and countervailing duty rates can depend on the written product scope, producer and exporter. An HTS code does not by itself establish the case rate.
A special rate requires qualifying origin, a valid preference claim and supporting records. The HTS symbol alone does not show whether a shipment is eligible.
