Executive Summary
Throughout 2026, the U.S. Department of Commerce and the International Trade Commission have maintained a genuinely active pace of antidumping and countervailing duty actions against imports from China. New orders have been issued on products ranging from fiberglass door panels, with duties reaching well into triple digits, to erythritol, a sugar substitute now facing substantial rates. Sunset reviews have confirmed the continuation of existing orders on corrosion inhibitors, wood mouldings, oil country tubular goods, passenger vehicle tires, kitchen shelving, and citric acid, among others. Administrative reviews remain underway across dozens of additional product categories, including aluminum foil, activated carbon, and various chassis and subassemblies. While most actions in 2026 have resulted in continued or new duties, a notable exception occurred in March, when the ITC rejected proposed tariffs on Chinese active anode material (graphite anodes)—a surprising reversal that spared a critical segment of the electric vehicle battery supply chain from a combined duty rate that would otherwise have reached roughly 160–170%. This analysis provides a comprehensive roundup of China-related trade remedy actions in 2026 and examines what these trends suggest for importers going forward.
China AD/CVD Roundup: A Comprehensive Review of 2026 Actions Targeting Chinese Imports
(2026年中国反倾销反补贴税综述：贸易救济行动全面扩张)
1 · New Orders: Duties Imposed in 2026
Fiberglass Door Panels — Duties Reaching Well Into Triple Digits
One of the more significant new AD/CVD actions of 2026 targeted fiberglass door panels from China. In early July 2026, the U.S. International Trade Commission made a unanimous affirmative final determination finding that U.S. fiberglass door panel producers had been materially injured by unfairly dumped and subsidized imports from China.
Commerce had previously published affirmative final determinations in mid-June 2026, finding meaningfully different rates depending on company cooperation status. Individually examined companies faced dumping margins of 41.82% and 104.31%, alongside individually calculated subsidy rates of 66.22% and 58.50% respectively. Separate-rate applicants that cooperated with the investigation but were not individually examined faced a combined 73.07% antidumping rate. Several named companies that did not cooperate with the investigation were assigned adverse-inference subsidy rates of 186.46%, and the China-wide entity — covering all producers and exporters not specifically listed — received an adverse-inference antidumping rate of 147.85%. The “all others” countervailing duty rate, applicable to companies not individually examined or named, was set at 60.64%.
The AD and CVD orders became applicable in early August 2026 and will generally remain in effect for a minimum of five years, subject to potential annual review through Commerce’s standard administrative review process.
A meaningful takeaway here: the substantial gap between cooperating and non-cooperating company rates serves as a fairly stark reminder of the consequences of failing to participate meaningfully in Commerce investigations. Importers sourcing from Chinese fiberglass door panel manufacturers may benefit from verifying their suppliers’ actual cooperation status with the underlying investigation.
Erythritol — Substantial Duties on a Widely Used Food Ingredient
In late March 2026, Commerce issued AD and CVD orders on erythritol from China. Antidumping cash deposit rates range broadly from roughly 85% up to over 180%, while countervailing duty cash deposit rates fall in a considerably lower range of roughly 4.5% to 8.6%. Erythritol, a sugar substitute widely used across food and beverage products, now faces substantial duties likely to meaningfully affect landed costs for importers operating in the food ingredients sector.
Temporary Steel Fencing — New Orders Issued
In mid-May 2026, Commerce issued AD and CVD orders on temporary steel fencing from China, affecting a fairly broad range of construction and event-related products relying on this equipment category.
Several Investigations Currently Underway
Beyond finalized orders, several new investigations remain in progress. A countervailing duty investigation concerning truck bed covers from China was initiated in mid-March 2026, following a petition filed in late February. A separate countervailing duty investigation covering certain choline salts from China was initiated in late July 2026, following a petition received in late June. And antidumping and countervailing duty investigations concerning n-cyclohexylbenzothiazole-2-sulfenamide, commonly known as CBS and used as a rubber accelerator in tire manufacturing, were initiated in June 2026.
Separately, in May 2026, a new AD/CVD case was filed against stationary and portable air compressors from China, Malaysia, and Vietnam, alleging both unfair subsidies and dumping across the affected countries.
Glyphosate — A Notable Exception
Not every action in 2026 has resulted in imposed duties. In a fairly notable development, AD and CVD injury investigations concerning glyphosate from China were ultimately terminated following withdrawal of the underlying petitions. The petitions, originally filed in late June 2026 by a major agricultural chemical company and its subsidiary, were subsequently withdrawn, bringing the investigation to a close without any duties ultimately imposed.
2 · Sunset Reviews: Orders Continued Throughout 2026
Sunset reviews periodically determine whether existing AD/CVD orders should be continued or instead revoked. Throughout 2026, Commerce and the ITC have continued numerous existing orders affecting Chinese products, generally finding that revocation would likely lead to continuation or recurrence of dumping, subsidization, and material injury to domestic industries.
Corrosion Inhibitors — Continued in Early August
In early August 2026, the ITC determined that revocation of existing AD and CVD orders on certain corrosion inhibitors from China would likely lead to continuation or recurrence of material injury. Commerce subsequently published a notice of continuation, with the orders covering tolyltriazole and benzotriazole in all grades and forms remaining in effect going forward.
Wood Mouldings and Millwork Products — Continued in Late June
In late June 2026, the ITC similarly determined that revocation of AD and CVD orders on wood mouldings and millwork products from China would likely lead to continuation or recurrence of material injury, with Commerce publishing a corresponding continuation notice shortly thereafter.
Additional Continuations Across Diverse Sectors
Oil country tubular goods from China, used extensively in oil and gas exploration and production, saw their AD and CVD orders continued in late June 2026. Orders on certain passenger vehicle and light truck tires from China have similarly been continued. Kitchen appliance shelving and racks from China saw their orders continued in April 2026. Citric acid and certain citrate salts from China had their orders continued in late May 2026. Crepe paper products from China saw continuation effective mid-July 2026. And polyethylene terephthalate film, sheet, and strip from China—alongside comparable products from India, Taiwan, and the United Arab Emirates—saw continuation effective late March 2026.
Separately, sunset reviews have been formally initiated, though not yet concluded, for several additional product categories including boltless steel shelving units prepackaged for sale, chassis and subassemblies, non-refillable steel cylinders, and small vertical shaft engines—all from China.
Mattresses — A Particularly High Continued Rate
A sunset review determination specifically found that revocation of the existing countervailing duty order on mattresses from China would likely lead to continuation or recurrence of countervailable subsidies at a rate approaching 98%—among the highest confirmed rates across this year’s sunset review activity.
3 · Administrative Reviews: Ongoing Activity Across Dozens of Categories
Administrative reviews can result in meaningful changes to AD/CVD cash deposit rates for specific companies and review periods. Numerous reviews involving Chinese products remain actively underway throughout 2026.
Activated Carbon and Aluminum Foil
Preliminary results for an administrative review of the antidumping order on activated carbon from China, covering the period from April 2024 through March 2025, found dumping margins in the range of roughly $0.83 to $0.86 per kilogram. An earlier review covering the prior twelve-month period had found considerably lower margins, illustrating how rates can shift meaningfully between review periods.
Separately, preliminary results for an administrative review of the antidumping order on aluminum foil from China, covering the same April 2024 through March 2025 period, found a dumping margin of roughly 62%.
Chlorinated Isocyanurates and Aluminum Extrusions
Preliminary results for a countervailing duty administrative review covering chlorinated isocyanurates from China, addressing the 2023 calendar year, found a subsidy rate of roughly 19% for one specific company, while the review was rescinded with respect to 41 additional companies found to have no reviewable entries during the relevant period.
Scope rulings have also been issued on aluminum extrusions from China covering the first quarter of 2026, with related administrative reviews continuing separately.
Additional Ongoing Reviews Worth Monitoring
Numerous additional administrative reviews have been initiated across a genuinely wide range of product categories, including common alloy aluminum sheet, crystalline silicon photovoltaic products, gas-powered pressure washers, wood moldings and millwork products, frozen warmwater shrimp, certain refrigerant chemicals, alloy and carbon steel threaded rod, corrosion inhibitors, disposable aluminum containers and related packaging products, truck and bus tires, wooden cabinets and vanities, and mobile access equipment and related subassemblies.
Scope rulings addressing forged steel fittings and walk-behind lawn mowers from China have also been issued during this period, clarifying which specific products fall within existing order coverage.
4 · The Graphite Anode Reversal: A Rare and Notable Exception
One of the more genuinely notable developments in 2026 was the ITC’s decision to reject proposed tariffs on Chinese graphite anodes—a critical component used in electric vehicle battery production.
One of the more genuinely notable developments in 2026 was the ITC’s decision to reject proposed tariffs on Chinese active anode material (AAM) — commonly referred to in industry coverage as graphite anodes — a critical component used in electric vehicle and energy-storage battery production.
In a 2-1 vote on March 12, 2026, the ITC issued a final negative determination, finding that Chinese AAM imports had not materially injured or threatened to materially retard the establishment of the relevant U.S. domestic industry (a somewhat different, and higher, legal standard than the “material injury” test applied in most AD/CVD cases, since the U.S. AAM industry was still in the process of being established). As a result, Commerce did not proceed to issue either AD or CVD orders on this product.
This represented a fairly striking reversal given the final rates Commerce had already calculated the prior month. In February 2026, Commerce’s final affirmative determinations put the combined antidumping and countervailing duty rate at roughly 160% to 170% for most Chinese exporters — a figure that would have applied on top of the existing 25% Section 301 tariff and a separate 10% global tariff already in effect on the product.
Why this particular case matters: the graphite anode reversal demonstrates that even within a genuinely aggressive enforcement environment, the ITC’s material injury determination remains a meaningful and independent hurdle within the overall process. Importers facing potential AD/CVD exposure should not assume duties are simply inevitable once an investigation begins—the ITC’s separate injury analysis represents a genuinely consequential part of the broader process.
5 · Key Trends and Enforcement Patterns Worth Understanding
A Genuinely Broad Sectoral Footprint
China-related AD/CVD actions in 2026 span an extraordinarily wide range of industries. Building materials, including fiberglass door panels, wood mouldings, and temporary steel fencing, represent one major category. Chemicals, spanning corrosion inhibitors, erythritol, glyphosate, choline salts, and CBS, represent another. Metals and steel products, including aluminum foil, aluminum extrusions, forged steel fittings, steel cylinders, oil country tubular goods, and steel shelving, form a substantial third category. Automotive-related products, including truck bed covers, passenger and truck tires, and various chassis products, represent a fourth. Consumer goods, spanning mattresses, kitchen shelving, disposable aluminum containers, and paper products, form a fifth category. Energy-related products, including crystalline silicon photovoltaic products and graphite anodes, represent a sixth. And food and agriculture products, including citric acid, frozen shrimp, and glyphosate, round out a seventh distinct category.
The China-Wide Rate Gap
Across multiple orders issued in 2026, non-cooperating companies have consistently faced meaningfully higher rates than companies that cooperated fully with the underlying Commerce investigations. The fiberglass door panel case illustrates this pattern clearly, with the China-wide antidumping rate settling considerably above the rates applicable to individually examined, cooperating companies. The erythritol case shows a similarly wide spread between highest and lowest applicable rates. And the graphite anode case, before its ultimate reversal, would have applied considerably different rates depending on individual company cooperation status.
A meaningful takeaway: companies that do not cooperate meaningfully with Commerce investigations tend to face the highest applicable duty rates by a considerable margin. Importers generally benefit from verifying that their suppliers have genuinely participated in any applicable reviews, rather than assuming cooperation status by default.
A Fairly Consistent Sunset Review Continuation Pattern
Nearly all sunset reviews concluded during 2026 have resulted in continuation of the underlying orders rather than revocation. This pattern suggests that once an AD/CVD order is established, it tends to remain in effect for many years—potentially decades in some cases—as domestic industries consistently demonstrate that revocation would likely lead to recurrence of material injury.
An Active Scope Ruling Trend
Multiple scope rulings have been issued throughout 2026 on various Chinese products, including aluminum extrusions, forged steel fittings, and walk-behind lawn mowers, among others. Scope rulings determine whether particular products genuinely fall within the coverage of existing AD/CVD orders—representing a genuinely important compliance consideration for importers whose products sit near the boundary of existing order language.
6 · Practical Considerations for Importers
Verifying AD/CVD Status Across the Full Product Portfolio
With new orders, continued orders, and numerous ongoing reviews collectively affecting dozens of product categories, importers generally benefit from verifying the current AD/CVD status of essentially every product sourced from China, rather than assuming a product remains duty-free simply because it was not previously subject to duties.
Confirming Supplier Cooperation Status
As the fiberglass door panel and erythritol cases both demonstrate clearly, non-cooperating suppliers face substantially higher duty rates than their cooperating counterparts. Importers may benefit from confirming that their suppliers have genuinely participated in relevant Commerce investigations and reviews, and obtaining reasonable documentation of that cooperation status where practical.
Monitoring Sunset Review Schedules
Sunset reviews generally occur every five years and can result in either continuation or revocation of existing orders. Importers may benefit from monitoring sunset review schedules relevant to products they source, and adjusting landed cost projections accordingly as review outcomes become known.
Tracking Administrative Review Results Closely
Administrative reviews can result in meaningful changes to applicable cash deposit rates, sometimes quite significant ones depending on the underlying facts. Importers generally benefit from tracking review results relevant to their products and adjusting duty deposits and pricing strategies accordingly as new determinations are published.
Considering Scope Ruling Requests Where Ambiguity Exists
Where genuine ambiguity exists about whether a particular product falls within the scope of an existing AD/CVD order, importers may benefit from considering a formal scope ruling request to Commerce. This process generally provides greater certainty and can help prevent costly surprises at the point of entry.
Preparing for Ongoing New Investigations
With new investigations continuing to be initiated on a fairly regular basis—covering products such as truck bed covers, choline salts, CBS, and air compressors in 2026 alone—importers generally benefit from monitoring Federal Register announcements closely and preparing to respond to Commerce questionnaires promptly if their suppliers are ultimately selected for individual examination.
Building Broader Compliance Capacity
Consistent with broader trade fraud enforcement priorities described in the DOJ-DHS Resource Guide, AD/CVD evasion generally remains a top enforcement priority for federal authorities. Importers are well served by maintaining robust compliance programs capable of verifying origin, classification, and valuation accurately—and ensuring that transshipment schemes are not inadvertently facilitating AD/CVD evasion within their broader supply chains.
7 · Conclusion: The China AD/CVD Landscape Heading Into Late 2026
The AD/CVD landscape affecting Chinese imports in 2026 is characterized by several consistent themes: new orders covering products ranging from fiberglass door panels to erythritol, each carrying rates reaching well into triple digits; continued orders confirmed through sunset reviews across a genuinely diverse set of product categories including corrosion inhibitors, wood mouldings, oil country tubular goods, tires, shelving, citric acid, crepe paper, and PET film; ongoing administrative reviews affecting dozens of additional product categories; new investigations continuing to emerge on products including truck bed covers, choline salts, CBS, and air compressors; and one particularly notable reversal, with the ITC’s rejection of proposed graphite anode tariffs standing out as a genuine exception to the broader pattern.
The underlying message for importers appears fairly consistent: China-related AD/CVD exposure remains broad, deep, and continuing to grow across 2026. Products not previously subject to duties may become subject to them through new investigations. Products already subject to existing duties may see their rates change meaningfully through administrative reviews. And products that appear, on their face, to fall outside existing orders may still ultimately be pulled within scope through formal scope rulings.
Importers who treat AD/CVD compliance as a one-time check performed at initial sourcing, rather than as an ongoing monitoring obligation requiring sustained attention, expose themselves to genuinely significant financial risk over time. The cost of non-compliance—whether arising through misclassification, undervaluation, or transshipment—has generally never been higher than in the current enforcement environment.
The broader takeaway: in 2026, China-related AD/CVD exposure is no longer a relatively niche concern affecting only a handful of specialized importers. It has become a genuinely mainstream compliance issue touching virtually every industry sector with meaningful China sourcing exposure. Importers are well served by treating AD/CVD due diligence as a genuinely core supply chain function, rather than an occasional afterthought addressed only when problems arise.
This analysis reflects AD/CVD actions involving China as announced through August 2026. Specific duty rates, order scopes, and review periods remain subject to official Federal Register notices and subsequent Commerce and ITC determinations. Importers should consult with customs counsel and trade compliance professionals for guidance tailored to their specific products and supply chains.
