The U.S. Department of Commerce has preliminarily determined that imports of monosodium glutamate (MSG) from Malaysia, made using glutamic acid from China, are circumventing antidumping duties on MSG from China. As a result, they have decided to suspend liquidation and require cash deposits for these imports. Importers and exporters must submit certifications demonstrating that MSG from Malaysia does not use Chinese glutamic acid to avoid these duties. Public comments and requests for a hearing are invited, and the findings will be verified before a final decision is made.
Simple Explanation
The U.S. government thinks some MSG, a kind of flavoring, is being mixed in Malaysia using stuff from China to avoid paying extra fees to bring it into the country, so they're asking sellers to show proof it isn't using the Chinese stuff.
