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

Pentafluoroethane (R-125) imported from China may fall within the scope of two U.S. Department of Commerce orders: antidumping case A-570-137 and countervailing case C-570-138. Because both an AD and a CVD order exist, importers should carefully review whether their goods are covered and verify current requirements before entry.

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 pentafluoroethane (R-125) in bulk or containerized form
•May include R-125 sold as a standalone refrigerant/fluorochemical
•May include R-125 whether packaged in cylinders, drums, or ISO tanks
•May include R-125 of Chinese origin regardless of purity grade specified in the scope
•May include R-125 intended for use in refrigerant blends before further blending
•May include R-125 imported for downstream processing

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

?Finished refrigerant blends may be treated differently depending on Commerce's written scope
?Other individual refrigerant gases (e.g., R-32 or R-134a) that are not R-125
?Products where R-125 is not the subject merchandise as defined in the scope
?Merchandise from countries other than China (which would fall under other orders, if any)

Scope control: Any HTS codes are screening references only; Commerce's written scope language controls whether a product is covered, and unfinished, in-process, or blended forms may still be covered depending on that scope.

Who it affects

This typically matters for importers, distributors, and manufacturers bringing in pentafluoroethane (R-125) or blends containing R-125 of Chinese origin, including those sourcing refrigerant gases for HVAC, refrigeration, or fire-suppression applications.

What the duty means

AD and CVD cash deposits are collected at entry and vary by exporter/producer combination and administrative review; rates can be high, and because both orders exist, both AD and CVD deposits may apply. A 0% cash-deposit rate is NOT an exemption—the order still applies and the entry must be declared.

Importer checklist — how to assess your risk

☐Gather the commercial invoice description and confirm the chemical identity as R-125.
☐Collect product spec sheets, safety data sheets, and material/purity composition details.
☐Document the intended use and whether the product is standalone R-125 or part of a blend.
☐Obtain country-of-origin support and manufacturing records for the merchandise.
☐Identify the exact manufacturer and exporter names and their producer/exporter combination.
☐Determine the tentative HTS classification for screening purposes only.
☐Confirm scope applicability with a licensed customs broker or trade counsel.
☐Do not rely only on supplier statements about coverage or origin.
☐Verify the applicable 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.
⚠Scope inquiries that may clarify whether specific forms or blends are covered.
⚠Using the wrong exporter/producer combination, which can change the applicable deposit rate.
⚠Misdeclaration or misclassification exposing the importer to penalties and retroactive duties.

The same product may become subject to orders in multiple countries over time, so importers should review each origin they source from independently and rely on verified facts rather than evasion strategies.

FAQ

Is there antidumping duty on Pentafluoroethane (R-125) from China?

There is an antidumping order (A-570-137) and a separate countervailing duty order (C-570-138) on R-125 from China; whether your specific goods are covered depends on Commerce's written scope, and importers should 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, the entry must be declared, and rates can change through administrative reviews.

Are blends or partially processed R-125 covered?

They may still be covered depending on Commerce's written scope language; importers should confirm how blends and in-process forms are treated rather than assuming exclusion.

Possible risk

Risk signal: Higher concern if the goods are pentafluoroethane (R-125) of Chinese origin; separate review is needed for blends, formulations, repackaged goods, and third-country processing. This does not state your goods are covered.

Bottom line: Pentafluoroethane (R-125) from China may be covered by A-570-137 (AD) and C-570-138 (CVD); confirm scope, origin, exporter/producer identity, and current deposit rates before entry.
