The linear hydraulic cylinders AD/CVD investigations have advanced following a preliminary finding of injury involving imports from five countries. Importers, equipment manufacturers, customs brokers, and drawback filers should now prepare for potential cash deposits, changing entry requirements, scope questions, and higher landed costs.
What the Preliminary ITC Determination Means
The Investigations Continue on Two Tracks
The U.S. International Trade Commission determined that there is a reasonable indication that imports of linear hydraulic cylinders are materially injuring the domestic industry. The antidumping investigations cover Canada, China, India, Mexico, and South Korea. The countervailing duty investigations cover China, India, and Mexico.
This preliminary injury finding does not establish that dumping or subsidization occurred, nor does it impose a final antidumping or countervailing duty order. It allows the investigations to continue. The Department of Commerce will generally evaluate dumping margins, subsidy rates, scope issues, and company-specific information, while the ITC later considers whether the domestic industry is materially injured or threatened with material injury.
The petitions were filed on July 29, 2026, and the ITC held its preliminary conference on August 19. The Commission ultimately voted 5-0 in favor of an affirmative preliminary injury determination, with one commissioner not participating. Commerce subsequently continued its separate antidumping and countervailing duty proceedings.
Preliminary Commerce Decisions Are the Next Operational Trigger
The most immediate concern for importers is Commerce's preliminary determinations. Preliminary countervailing duty decisions are expected around November 2026, while preliminary antidumping determinations are expected around January 2027, although agency schedules can change.
An affirmative preliminary determination typically causes U.S. Customs and Border Protection to suspend liquidation and require cash deposits for covered entries made on or after the applicable effective date. If critical circumstances are found, requirements can sometimes apply retroactively to certain earlier entries.
Importers should not wait for final orders before evaluating exposure. Purchase orders, customs bonds, broker instructions, product classifications, supplier representations, and landed-cost forecasts may all require attention before preliminary deposit rates become effective.
Scope and Classification Require Product-Level Review
HTSUS Subheadings Are Starting Points, Not Final Answers
Products associated with the investigations are entered under HTSUS subheadings 8412.21.00 and 8412.90.90. These provisions generally cover linear-acting hydraulic power engines and motors, including cylinders, and certain related parts.
Importers should not assume that an HTSUS number alone determines whether merchandise is subject to an AD/CVD case. The written product scope generally controls. Tariff classifications assist administration and targeting, but they are not substitutes for comparing the physical merchandise against the complete scope description.
A useful product review should document the cylinder's construction, dimensions, operating characteristics, material composition, end use, assembly condition, and included components. Technical drawings, bills of materials, catalogs, model numbers, and supplier specifications can be more important than commercial descriptions such as hydraulic component, actuator, machinery part, or replacement assembly.
Parts and Third-Country Processing May Create Complexity
Potential coverage of barrels, piston rods, components, unfinished articles, and assemblies requires careful monitoring as Commerce develops the scope. An importer purchasing complete cylinders can usually identify the product more readily than a company importing individual parts or incorporating subject-country components into equipment assembled elsewhere.
Third-country assembly does not automatically remove AD/CVD exposure. Depending on the final scope language and subsequent agency analysis, Commerce may consider where components originated, the extent of processing, and whether the imported article falls within the physical description of covered merchandise.
Importers should map supply chains beyond the country shown on the commercial invoice. The review should identify the producer, component origins, country of manufacture, assembly location, and any supplier changes made after the petition was filed. Customs brokers should also avoid making scope decisions from abbreviated invoice descriptions without supporting technical information.
Where uncertainty remains, importers may need trade counsel to evaluate scope procedures and available agency guidance. Classification and origin analyses should be documented separately because a correct tariff classification does not necessarily resolve AD/CVD coverage.
Managing Cash Deposits, Entries, and Drawback
Open Orders and Entry Data Need Immediate Attention
Importers should identify open purchase orders, goods in production, in-transit shipments, warehouse inventory, and unliquidated entries involving linear hydraulic cylinders or related parts from the five named countries. This inventory should include the manufacturer, exporter, entered value, anticipated entry date, HTSUS classification, and expected use.
Supplier-specific rates can differ significantly from country-wide or all-others rates. Importers therefore need accurate manufacturer and exporter identities, not merely the name of an intermediary, distributor, or trading company. Customs brokers will also need the correct AD/CVD case numbers once Commerce issues instructions for affirmative preliminary determinations.
Commercial agreements should be reviewed for responsibility for additional duties, deposit increases, post-entry corrections, record production, and reimbursement certifications. Because cash deposits are estimates rather than necessarily the final liability, an entry can remain financially uncertain until liquidation after the relevant administrative process.
Importers should incorporate potential deposits into landed-cost planning without treating an alleged margin as a confirmed final rate. Procurement teams may also evaluate sourcing alternatives, but any country-of-origin change must reflect genuine production facts rather than routing or minimal processing.
AD/CVD and Ordinary Duties Must Remain Separate
Antidumping and countervailing duties are generally not eligible for duty drawback. Ordinary customs duties paid on the same entry may still qualify when statutory and procedural drawback requirements are satisfied, such as through a qualifying exportation or destruction.
This distinction makes charge-level accounting essential. An entry may include ordinary customs duty, merchandise processing fees, antidumping deposits, countervailing duty deposits, and other charges. A drawback calculation should not treat the entire payment to CBP as potentially recoverable.
Importers and brokers should preserve entry summaries, line-level duty data, case numbers, deposit amounts, liquidation status, inventory records, and export documentation. When hydraulic cylinders are incorporated into machinery that is later exported, the drawback analysis may also require careful linkage between imported merchandise, manufacturing activity, substituted merchandise where permitted, and the exported article.
Separating AD/CVD amounts from eligible ordinary duties protects claim accuracy and supports more reliable refund forecasting. It also prevents potential AD/CVD exposure from obscuring legitimate drawback opportunities elsewhere in the same import program.
- On September 30, 2026, the USITC determined by a 5-0 vote (one commissioner recused) that there is a reasonable indication of material injury to the U.S. industry from allegedly dumped linear hydraulic cylinders imported from Canada, China, India, Mexico, and South Korea, plus subsidized imports from China, India, and Mexico. The investigations (Nos. 701-TA-802-804 and 731-TA-1799-1803) now move to the final phase, with Commerce continuing its AD/CVD work. The public ITC report is due by November 16, 2026.
- The ITC determinations were published in the Federal Register on October 14, 2026. Covered products fall under HTSUS subheadings 8412.21.00 and 8412.90.90. Petitioners include the Hydraulic Cylinders Fair Trade Coalition and nine U.S. producers such as Aggressive Hydraulics Inc., Hol-Mac Corporation, and Texas Hydraulics Inc.
- Commerce initiated the AD investigations covering all five countries and CVD investigations for China, India, and Mexico on September 9, 2026. Alleged dumping margins range from 56.79-157.12 percent (Mexico) to 248.33-744.85 percent (Canada). CVD preliminary determinations are scheduled around November 12, 2026, with AD preliminaries around January 26, 2027.
- Trade law practitioners flagged a mid-September 2026 deadline for scope comments. Petitioners have advocated a broad scope that includes steel barrels, piston rods, related components, and potentially cylinders assembled in third countries using subject-country parts.
Frequently Asked Questions
Which Countries Are Covered by the Hydraulic Cylinder Investigations?
The antidumping investigations cover Canada, China, India, Mexico, and South Korea. Countervailing duty investigations also apply to China, India, and Mexico. Coverage ultimately depends on the merchandise, producer, exporter, origin, applicable scope language, and Commerce instructions, not merely the country from which goods were shipped.
Are Cash Deposits Already Required?
The ITC's preliminary injury determination does not itself establish cash deposit requirements. Deposits typically begin after Commerce issues an affirmative preliminary antidumping or countervailing duty determination and CBP receives corresponding instructions. Effective dates can vary, particularly if critical circumstances or other special timing rules apply.
Do HTSUS Codes 8412.21.00 and 8412.90.90 Automatically Establish Coverage?
No. These subheadings identify product categories associated with the proceedings, but the written scope generally controls. Merchandise entered under another subheading may potentially be covered if it satisfies the scope, while merchandise entered under a listed subheading may fall outside the case when its characteristics do not match the covered product.
Can AD/CVD Cash Deposits Be Recovered Through Duty Drawback?
Generally, no. Antidumping and countervailing duties are excluded from drawback. However, ordinary customs duties paid on the same entry may remain eligible if all applicable drawback conditions are met. Claim calculations should clearly separate ordinary duties from AD/CVD deposits and assessments.
What Should Customs Brokers Request From Importers?
Brokers should request complete manufacturer and exporter identities, technical product descriptions, part numbers, country-of-origin support, entry dates, and any available scope analysis. They should also confirm that importer instructions address the appropriate AD/CVD case numbers once those numbers and deposit requirements become operational.
How Stable Software Can Help
Keep Recoverable Duties Separate From AD/CVD
The hydraulic cylinder investigations illustrate why drawback programs need precise treatment of duty categories. AD/CVD amounts are generally ineligible, but ordinary customs duties on qualifying merchandise may still support refunds when the relevant exportation or destruction requirements are met.
DrawbackAI is flat-license duty drawback software that U.S. customs brokers can white-label for importer clients while filing under their own filer codes. Stable Software charges a flat software license and never takes a percentage of the refund. Brokers seeking to expand drawback services without surrendering a share of client recoveries can evaluate how DrawbackAI fits their operating model.
