The Tariff Refund Checker is an online tool designed to help businesses determine if they are eligible for refunds on tariffs and import duties. It evaluates various factors such as the nature of the item, its value, and any applicable regulations to assess whether a refund is possible. Users can submit details about their tariff or import duty bill, returned item, CAPE issue, or carrier invoice directly through the tool's user-friendly interface. The checker provides an analysis and recommendations on whether a broker review is warranted for potential refunds.
