This educational explainer covers the U.S. antidumping (AD) duty order on monosodium glutamate (MSG) from China, identified by case number A-570-992. This is an AD order only; no countervailing duty case is listed here for this product from China. Importers should verify whether their specific goods may fall within the order's scope.

Scope — simplified screening examples, not full legal scope

The official written scope controls. The examples below are screening references only.

Products that may be covered (examples)

•May include monosodium glutamate (MSG) in crystalline or powdered form
•May include MSG sold under trade or brand names but chemically identical
•May include MSG regardless of grade or purity level where it meets the scope description
•May include MSG imported in bulk packaging for food or industrial use
•May include MSG in retail-sized consumer packaging
•May include MSG that has been blended only minimally where the scope still applies

Products that may require separate review or may fall outside this order

?Certain seasoning blends or finished food products containing MSG as one ingredient among many may fall outside the order (verify)
?Other glutamate compounds that are not sodium salts may be outside scope (verify)
?Products that are chemically distinct flavor enhancers rather than MSG may be excluded (verify)
?MSG originating from countries other than China would not be covered by this particular order (separate orders may apply)

Scope control: Any HTS codes are screening references only; Commerce's written scope language controls whether a product is covered, and blended, repackaged, or intermediate forms may still fall within scope depending on that language.

Who it affects

This typically matters for importers, distributors, and food manufacturers bringing MSG of Chinese origin into the United States, including those buying through traders or third-country intermediaries.

What the duty means

Antidumping duties are collected as cash deposits at entry; rates vary by exporter/producer and administrative review and can be substantial. A 0% cash-deposit rate is NOT an exemption — the order still applies and entries must be declared as subject merchandise.

Importer checklist — how to assess your risk

☐Gather the commercial invoice with the exact product description and chemical name
☐Collect product photos, spec sheets, and certificates of analysis showing composition and purity
☐Confirm the material composition to determine whether the product is MSG as described in the scope
☐Document the intended use (food additive, industrial, etc.)
☐Obtain country-of-origin support and manufacturing records
☐Identify the exact manufacturer, exporter, and producer/exporter combination
☐Determine the tentative HTS classification for screening purposes
☐Consult a licensed customs broker or trade attorney to confirm scope
☐Verify the applicable cash-deposit rate against current Commerce review results and CBP AD/CVD messages before filing, and do not rely only on supplier statements

Risks to watch

⚠Circumvention or transshipment findings where MSG is routed through a third country to disguise Chinese origin
⚠Scope inquiries that may broaden or clarify coverage of specific product forms
⚠Declaring the wrong exporter/producer combination and applying an incorrect deposit rate
⚠Misdeclaration or misclassification penalties for failing to declare subject merchandise

The same product may be subject to separate orders in other countries — for example, MSG from Indonesia has its own case — so each country of origin should be reviewed independently without any attempt to evade duties.

FAQ

Is there antidumping duty on monosodium glutamate from China?

There is a U.S. antidumping duty order on MSG from China under case number A-570-992; whether your specific goods fall within its scope depends on Commerce's written scope language and should be verified.

Does a 0% deposit rate mean no duty?

No. A 0% cash-deposit rate is not an exemption — the order still applies, entries must be declared as subject merchandise, and rates can change through administrative reviews.

Are blended or repackaged MSG products covered?

They may still be covered depending on Commerce's scope language; minimally processed, blended, or repackaged forms can fall within scope, so importers should verify with a licensed broker.

Possible risk

Risk signal: Higher concern if the goods are crystalline or powdered MSG of Chinese origin; a separate review is needed for seasoning blends, formulations, repackaged goods, and any third-country processing.

Bottom line: MSG from China may be covered by antidumping order A-570-992; confirm scope, origin, exporter/producer identity, and current cash-deposit rates before entry.

Not a scope determination or filing advice — confirm coverage and current deposit rates with a licensed customs broker and the latest Commerce/CBP instructions before entry.
