It is important as an importer to inquire about imported products that are subject to anti-dumping or countervailing duties. As an importer, if you purchase goods subject to these types of duties, you will likely have to pay SIMA duties, otherwise you may have to pay additional duties, interest, etc. You can deal with a customs broker, who will verify whether your products are subject to anti-dumping or countervailing duties and guide you through the refund of these duties under SIMA.
