How to check if a business qualifies for US tariff refunds?

US importers of record who directly paid the tariffs or the person who takes ownership of the goods once they have cleared customs may be eligible for a refund, US Chamber of Commerce said. Refunds are only available for tariffs applied under IEEPA. Refunds are not available for Section 232, Section 301, Section 201, anti-dumping and countervailing duties.
