The U.S. Department of Commerce is set to implement new countervailing tax rates on shrimp exporters from Vietnam, India, Indonesia, and Ecuador, which together make up 90% of U.S. shrimp imports in 2023. The rates, which will be effective immediately upon publication in the Federal Register, vary significantly, with Vietnam's Tongshun facing a steep 196.41% tax, while other rates range from 1.69% to 13.41% for Ecuadorian exporters and around 4.72% to 3.89% for some Indian exporters. These preliminary taxes could be refunded if it's later determined that the exporters are not benefiting from harmful subsidies, with final tax rates expected to be finalized in the coming fall and winter.
