Imports of truck bed covers from China now face significant preliminary antidumping exposure, with cash deposit rates ranging from 46.77% to 107.41%. Importers and customs brokers must align product scope, supplier combinations, entry dates, and companion countervailing duty requirements before filing or forecasting landed costs.
Preliminary Antidumping Rates and Effective Dates
The preliminary affirmative less-than-fair-value determination in case A-570-223 covers sales examined during the period from July 1 through December 31, 2025. It establishes preliminary dumping margins and directs U.S. Customs and Border Protection to suspend liquidation and collect antidumping cash deposits for covered entries made on or after October 1, 2026.
Published Margins and Cash Deposit Rates
The cash deposit rates are slightly lower than the corresponding weighted-average dumping margins because of adjustments for subsidy offsets:
| Exporter or Entity | Dumping Margin | Adjusted Cash Deposit Rate |
|---|---|---|
| Hangzhou Golden Sun Autoparts Co., Ltd. | 51.35% | 51.17% |
| Wenzhou Tianmao Automobile Parts Co., Ltd. and Wenzhou Chaoming Auto Parts Co., Ltd., treated as a single entity | 46.95% | 46.77% |
| Eligible non-examined separate-rate producer-exporter combinations | 49.56% | 49.38% |
| China-wide entity | 107.58% | 107.41% |
These rates are preliminary deposit requirements, not final duty assessments. Final antidumping liability is generally determined through subsequent administrative procedures and may be higher or lower than the amount deposited at entry. Importers therefore need to treat the deposit as both an immediate cash requirement and a continuing duty-risk position.
The Final Determination Has Been Postponed
At Golden Sun’s request, the final determination has been postponed until no later than 135 days after publication. The provisional measures period has also been extended to no more than six months. This gives Commerce additional time to complete its analysis, but it also extends the period during which importers may need to fund preliminary deposits while liquidation remains suspended.
Products Within the Truck Bed Cover Scope
Scope analysis is especially important because the investigation reaches multiple truck bed cover designs, materials, and packaging configurations. Product descriptions used in catalogs or commercial invoices may not be sufficient to establish whether merchandise is covered.
Included Designs, Dimensions, and Materials
The scope generally includes truck bed covers with an actual width of 45 to 75 inches and an actual length of 55 to 100 inches. Covered forms include folding, roll-up, one-piece, and retractable designs made from materials such as aluminum, steel, fiberglass, carbon fiber, plastic, or water-resistant fabric.
Mounting hardware is also included when it accompanies the cover and is entered or invoiced with it. Mounting kits entered or invoiced with the truck bed cover may therefore form part of the covered merchandise rather than a separate, duty-free accessory. Importers should review bills of materials, packaging specifications, purchase orders, and invoice line structures to identify these configurations consistently.
The listed tariff classification, 8708.29.5160, is provided for customs convenience. The written product description is dispositive, so classification under a different tariff provision does not necessarily remove an otherwise covered product from the proceeding.
Key Scope Exclusions
Truck caps and camper shells that increase the height of the truck bed by at least 12 inches are excluded. The scope also excludes merchandise already covered by existing antidumping or countervailing duty orders, including certain products subject to orders on aluminum extrusions from China.
These exclusions require evidence rather than assumptions. An importer relying on the truck-cap exclusion should generally retain dimensional drawings and product specifications demonstrating the required height increase. When relying on an existing-order exclusion, compliance teams should document why the merchandise falls within that other order and ensure the correct case treatment is reported. Mixed-material products and assemblies incorporating aluminum extrusions may require particularly careful analysis.
Cash Deposit and Entry Compliance Priorities
The operational impact extends beyond applying a percentage to entered value. The correct antidumping cash deposit rate depends on the exporter-producer combination, the identity of the Chinese supplier, the entry date, and the status of companion countervailing duty provisional measures.
Combination Rates and China-Wide Exposure
Separate rates generally apply only to the producer-exporter combinations that qualified for them. A listed exporter shipping merchandise from an unapproved producer does not automatically receive the exporter’s lower rate. Combinations without an applicable separate rate may be subject to the 107.41% China-wide cash deposit rate.
For shipments exported through a third country, CBP generally applies the rate associated with the Chinese producer or exporter that supplied the merchandise. Brokers should not substitute the country of shipment, invoicing intermediary, or third-country seller for the relevant Chinese party. Manufacturer identification must be captured before entry filing and matched against the applicable case instructions.
Importers should establish controls that validate:
- The actual manufacturer and exporter for every shipment
- Whether the producer-exporter combination has a separate rate
- The entry date relative to the October 1, 2026 effective date
- The declared customs value used to calculate deposits
- Whether companion antidumping or countervailing duty cases apply
- Whether any scope exclusion is supported by technical records
Interaction With Countervailing Duty Deposits
Truck bed covers from China are also subject to a companion countervailing duty investigation. Preliminary CVD rates range from 8.72% for Hangzhou Golden Sun Auto Parts to 100.95% for certain companies subject to adverse facts available, with a 20.25% all-others rate.
AD and CVD deposits may apply concurrently, creating substantial combined cash requirements. The published AD deposit rates reflect subsidy-offset adjustments while CVD provisional measures remain effective. If those provisional measures expire before the AD provisional period ends, CBP may be instructed to collect the unadjusted AD rates instead: 51.35%, 46.95%, 49.56%, or 107.58%, as applicable. Deposit teams should monitor case-message changes rather than hard-code the initially adjusted rates for future entries.
- Commerce issued a preliminary affirmative LTFV determination on truck bed covers from China (A-570-223) on September 29, 2026 (published in the Federal Register October 1, 2026; 91 FR 62495), finding sales at less than fair value during the POI of July 1–December 31, 2025; cash deposit requirements (adjusted for subsidy offsets) took effect for entries on or after October 1, 2026.*
- Estimated weighted-average dumping margins/cash deposit rates include Hangzhou Golden Sun Autoparts Co., Ltd. at 51.35%/51.17%; Wenzhou Tianmao Automobile Parts Co., Ltd./Wenzhou Chaoming Auto Parts Co., Ltd. (single entity) at 46.95%/46.77%; multiple non-examined separate-rate companies at 49.56%/49.38%; and the China-wide entity at 107.58%/107.41% (AFA). The AD final is scheduled around February 15, 2027.
- Companion CVD investigation (C-570-224) had a preliminary affirmative determination published July 31, 2026 (rates 8.72% for Hangzhou Golden Sun Auto Parts to 100.95% AFA for several companies, 20.25% all-others), with cash deposits effective from that date; the CVD final was due around October 13, 2026 (unless postponed). ITC final-phase injury investigations include a staff report around October 1, 2026, and hearing on October 15, 2026.
- Industry coverage highlighted the AD cash deposits taking effect October 1 (e.g., International Trade Today and Law360 reports of September 29–30, 2026 noting potential triple-digit combined duties). A practitioner post on X on October 1, 2026, summarized the FR notice, rates of 46.95%–107.58% (cash deposits 46.77%–107.41%), and October 1 effective date.
Frequently Asked Questions
When Did the Antidumping Cash Deposit Requirement Begin?
Suspension of liquidation and preliminary antidumping cash deposits apply to covered truck bed covers entered, or withdrawn from warehouse for consumption, on or after October 1, 2026. Earlier entries are generally outside this preliminary suspension instruction, although separate proceedings or later determinations may require independent review.
Does HTSUS Classification Determine Whether a Cover Is Subject?
No. HTSUS 8708.29.5160 is identified for convenience, but the written scope controls. Merchandise classified elsewhere may still be covered if its physical characteristics match the scope. Conversely, classification under the listed subheading does not by itself establish that every product is subject.
Can an Importer Use a Listed Exporter’s Rate for Every Shipment?
Not necessarily. Separate rates are typically tied to approved producer-exporter combinations. A shipment involving a different producer may receive the China-wide rate even when the exporter appears on a separate-rate list. Importers and brokers should verify both parties before transmitting the entry summary.
Are Preliminary Cash Deposits the Importer’s Final Duty Liability?
No. Cash deposits secure estimated duties while the investigation and later duty administration continue. Final assessment rates may differ from the preliminary deposits. Importers should preserve entry-level records, account for potential duty changes, and avoid treating the deposited amount as a fixed final cost.
Do Antidumping and Countervailing Deposits Apply at the Same Time?
They can. When both provisional measures are active, a covered entry may require separate AD and CVD deposits. The combined impact can be substantial, particularly for companies subject to adverse-facts-available rates. Importers should model each case separately and monitor whether provisional measures expire or deposit instructions change.
How Stable Software Can Help
Strengthening AD/CVD Entry Controls
Managing truck bed cover entries requires reliable links among products, manufacturers, exporters, case numbers, effective dates, and deposit rates. Manual spreadsheets can leave brokers and importers exposed to outdated rates, unapproved supplier combinations, and inconsistent scope decisions.
Stable Software helps trade teams centralize customs data, automate entry validations, monitor antidumping and countervailing duty exposure, and maintain defensible audit trails. Configurable workflows can flag China-wide rate risk, identify missing manufacturer data, and support deposit forecasting before cargo reaches the port. This gives customs brokers, auto-accessory importers, and compliance managers stronger control over high-value entries while reducing the operational burden of changing trade-remedy requirements.
