Effective/entry-specific deposit and liquidation treatment depends on Commerce and CBP instructions, not only the publication date.

Potassium phosphate salts imported from China may be covered by two U.S. Department of Commerce orders: antidumping case A-570-962 and countervailing duty case C-570-963. Importers researching these goods should verify scope, origin, and current cash-deposit rates before making entry, because both an AD and a CVD order may apply.

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 monopotassium phosphate (MKP) in dry or granular form
•May include dipotassium phosphate (DKP)
•May include tripotassium phosphate (TKP)
•May include tetrapotassium pyrophosphate (TKPP)
•May include various potassium phosphate salts in food, industrial, or technical grades
•May include such salts whether sold in bulk or packaged for further processing

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

?Sodium-based phosphate salts (a different chemistry) may fall outside this order
?Phosphoric acid itself, as distinct from finished potassium phosphate salts, may be outside scope
?Blended fertilizer formulations containing potassium phosphate may be treated differently depending on scope
?Products of a country other than China are not covered by these specific China cases
?Ammonium or calcium phosphate salts may fall outside this particular order

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

Who it affects

This typically matters for importers, distributors, and manufacturers sourcing potassium phosphate salts (such as MKP, DKP, TKP, or TKPP) of Chinese origin for food, industrial, agricultural, or technical uses.

What the duty means

If covered, importers may owe AD and/or CVD cash deposits at the time of 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. Because both an AD (A-570-962) and a CVD (C-570-963) order exist, both types of deposits may apply.

Importer checklist — how to assess your risk

☐Gather the commercial invoice description and confirm the exact chemical name and grade
☐Collect product photos, spec sheets, and a certificate of analysis showing composition
☐Document material composition and the specific potassium phosphate salt type
☐Record the intended use (food, industrial, agricultural, technical)
☐Assemble country-of-origin support, including manufacturing records
☐Identify both the manufacturer/producer and the exporter by full legal name
☐Verify the specific producer/exporter combination against current Commerce results
☐Determine the correct HTS classification and treat it as a screening aid only, not a scope decision
☐Confirm scope and applicability with a licensed customs broker or trade counsel, do not rely only on supplier statements, and verify the current cash-deposit rate against 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 is asked to rule whether a specific product or blend is covered
⚠Applying the wrong exporter/producer combination and therefore the wrong deposit rate
⚠Misdeclaration or failure to declare, which can trigger penalties and retroactive duty liability

The same product can be subject to trade-remedy orders from multiple countries, so importers should independently review each country of origin they source from without pursuing any evasion of applicable duties.

FAQ

Is there antidumping duty on potassium phosphate salts from China?

There is a U.S. antidumping order identified as case A-570-962 covering certain potassium phosphate salts from China, alongside a countervailing duty order under case C-570-963. Whether your specific product is covered depends on Commerce's written scope, so verify before entry.

Does a 0% deposit rate mean no duty?

No. A 0% cash-deposit rate is not an exemption. The order still applies, entries must still be declared under the case, and the rate can change through administrative reviews.

Are parts or unassembled potassium phosphate salts covered?

Potassium phosphate salts are a chemical product rather than an assembled good, but various forms, grades, and blends may still fall within or outside Commerce's scope. Confirm the specific form and composition against the written scope language.

Possible risk

Risk signal: Higher concern if the goods are potassium phosphate salts (such as MKP, DKP, TKP, or TKPP) of Chinese origin; a separate review is needed for blends, formulations, repackaged goods, and third-country processing. This does not mean the goods are covered.

Bottom line: Potassium phosphate salts from China may be covered by AD case A-570-962 and CVD case C-570-963; confirm scope, origin, exporter/producer identity, and current 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.
