The United States maintains both an antidumping (AD) order (A-570-160) and a countervailing duty (CVD) order (C-570-161) on 2,4-dichlorophenoxyacetic acid (2,4-D) from China. Importers of this herbicide chemical from China should review whether their goods may fall within the scope of these Commerce orders, as both AD and CVD cash deposits may apply.
Scope — simplified screening examples, not full legal scope
The official written scope controls. The examples below are screening references only.
- •2,4-dichlorophenoxyacetic acid (2,4-D) in technical/acid form that may originate in China
- •2,4-D produced in China and imported as an active herbicide ingredient
- •Bulk 2,4-D acid shipments that may fall within the written scope
- •2,4-D that may be entered directly from China or through third parties
- •Chinese-origin 2,4-D acid intended for further formulation into herbicide products
- ?Certain 2,4-D derivatives (such as specific esters or amine salts) may fall outside the acid-form scope depending on Commerce's written language
- ?Finished, packaged herbicide formulations may be treated differently — importers should verify
- ?Other phenoxy herbicides not identified in the written scope
- ?2,4-D of a different country of origin (though separate orders may apply to that origin)
- ?Chemically distinct compounds that share only naming similarities
Who it affects
This typically matters for importers, formulators, and distributors bringing in 2,4-D acid or 2,4-D-based herbicide inputs of Chinese origin, and for anyone sourcing this active ingredient through intermediaries.
What the duty means
If covered, importers post cash deposits at entry; AD and CVD deposits may both apply because both orders exist. Rates vary by exporter/producer and administrative review and can be high. A 0% cash-deposit rate is NOT an exemption — the order still applies and entries must be declared.
Importer checklist — how to assess your risk
- ☐Gather the commercial invoice with the exact chemical description and form (acid, ester, salt).
- ☐Collect product spec sheets, technical data, and chemical composition/CAS details.
- ☐Document the intended use of the material (herbicide active ingredient vs. other).
- ☐Obtain country-of-origin support and manufacturing records tracing the material to its producer.
- ☐Identify the manufacturer and exporter names and confirm the specific producer/exporter combination.
- ☐Confirm HTS classification for screening, understanding it does not determine scope.
- ☐Consult a licensed customs broker or trade counsel to confirm scope for your specific product.
- ☐Do not rely only on supplier statements about coverage, origin, or duty status.
- ☐Verify the applicable cash-deposit rate against current Commerce results and CBP AD/CVD messages before filing.
Risks to watch
- ⚠Circumvention or transshipment findings if goods are routed through third countries to disguise Chinese origin.
- ⚠Scope inquiries where Commerce may clarify whether a specific 2,4-D form or derivative is covered.
- ⚠Using the wrong exporter/producer combination and applying an incorrect (often lower) deposit rate.
- ⚠Misdeclaration of origin or product, which can lead to penalties, retroactive duties, and enforcement action.
