The U.S. Department of Commerce maintains an antidumping (AD) duty order (case A-570-124) on certain vertical shaft engines between 99cc and up to 225cc, and parts thereof, from China. This is an AD order only; no countervailing (CVD) case is listed here. Importers of these small engines or engine parts from China should carefully review whether their goods may fall within its 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)

•Vertical shaft gasoline engines rated between 99cc and up to 225cc that may be used in lawn mowers and similar outdoor power equipment
•Small vertical shaft engines imported as standalone units within the stated displacement range
•Certain engine parts and components of such vertical shaft engines, as described in the written scope
•Engines within the covered displacement range imported already assembled onto or incorporated into equipment, depending on scope language
•Replacement or aftermarket engine parts for covered vertical shaft engines
•Unassembled or partially assembled small vertical shaft engine kits that may fall within scope

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

?Horizontal shaft engines, which are generally a different configuration
?Engines with displacement below 99cc or above 225cc, outside the stated range
?Larger vertical shaft engines used in heavy equipment beyond the covered displacement
?Electric or battery-powered motors rather than internal-combustion gasoline engines
?Finished consumer products where the engine is not the covered merchandise (verify against scope)

Scope control: Any HTS codes are screening references only; Commerce's written scope language is what controls whether a product is covered, and parts, unfinished, or unassembled engines may still be covered depending on that scope.

Who it affects

This typically matters for importers of small gasoline vertical shaft engines (99cc-225cc) from China, importers of engine parts, and companies importing outdoor power equipment that may contain covered engines.

What the duty means

Covered goods generally require an AD cash deposit at the time of entry; 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. This order also involved a critical circumstances finding, meaning certain past entries could be subject to retroactive duties.

Importer checklist — how to assess your risk

☐Gather the commercial invoice with a precise product description including engine displacement in cc.
☐Collect product photos, spec sheets, and technical documentation showing shaft orientation and displacement.
☐Confirm the material composition and configuration (vertical vs. horizontal shaft, gasoline vs. electric).
☐Document the intended use and end application of the engine or part.
☐Verify and retain country-of-origin support for the engine and key components.
☐Identify the exact manufacturer and exporter names and confirm the specific producer/exporter combination.
☐Determine the correct HTS classification as a screening step, not a scope conclusion.
☐Consult a licensed customs broker or trade counsel to confirm scope and applicable AD treatment; do not rely only on supplier statements.
☐Verify the current cash-deposit rate against the latest Commerce administrative review 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 specific engines or parts are covered.
⚠Applying the wrong exporter/producer combination and therefore the incorrect deposit rate.
⚠Misdeclaration, undervaluation, or misclassification exposing the importer to penalties and retroactive duty assessment.

Small vertical shaft engines may be subject to trade orders in different countries, so importers should independently review each country of origin without engaging in any origin-manipulation.

FAQ

Is there antidumping duty on small vertical shaft engines from China?

There is an AD order (case A-570-124) on certain vertical shaft engines between 99cc and up to 225cc, and parts thereof, from China. Whether your specific goods are covered depends on Commerce's written scope, so 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 merchandise must be declared, and rates can change through administrative reviews, so importers should confirm current rates before filing.

Are parts or unassembled engines covered?

Parts and unassembled or partially assembled engines may still fall within scope depending on Commerce's written scope language; importers should verify rather than assume they are outside the order.

Possible risk

Risk signal: Higher concern if the goods are gasoline vertical shaft engines between 99cc and up to 225cc of Chinese origin; a separate review is needed for engine parts, unassembled kits, engines incorporated into finished equipment, and any third-country processing.

Bottom line: Small vertical shaft engines (99cc-225cc) and parts from China may be covered by AD case A-570-124; 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.
