Monosodium Glutamate — China — A-570-992

An AD/CVD measure is a U.S. trade remedy that may apply to imported goods covered by an antidumping (AD) or countervailing duty (CVD) proceeding. For a product described as Monosodium Glutamate, the key issue is whether the imported merchandise fits the measure’s legal product scope—not simply whether the commercial description, ingredient name, or tariff classification looks similar.

AD duties address imports that are allegedly sold at less than fair value, while CVD duties address benefits that a foreign government is found to have provided to producers or exporters. These measures typically affect importers, foreign exporters, manufacturers, and sometimes specific product forms or origins. An importer may face additional cash-deposit requirements, entry documentation obligations, and later duty assessments, so the scope and current official instructions should be reviewed carefully.

The Harmonized Tariff Schedule (HTS) classification can help identify potentially relevant entries, but it does not by itself decide whether merchandise is covered. Coverage generally depends on the written scope, including product characteristics, composition, packaging, exclusions, and country or producer/exporter details. If the facts are unclear, a customs broker or trade-remedy specialist may need to analyze the scope before importation.

What to check

• Read the official measure scope and compare it with the product’s composition, physical form, packaging, and intended use; do not rely on the product name alone.
• Confirm the correct HTS classification, but treat it as a screening tool rather than proof that the goods are included or excluded.
• Check the country of origin and the actual manufacturer and exporter, because AD/CVD treatment can depend on those facts.
• Review the current official cash-deposit, certification, and entry-reporting instructions before filing an entry.
• Keep product specifications, supplier records, origin support, and scope-analysis documents; ask a customs broker or trade-remedy counsel about borderline products.
