What Are Countervailing Duties and How Do They Work

In April 2025, the US Department of Commerce set final countervailing duty rates on solar cells from four Southeast Asian countries. Cambodia's country-wide rate: 3,400%. Not a typo. Importers who had posted cash deposits at 729% based on the preliminary determination now owed nearly five times more per entry. Countervailing duties are additional import duties that US Customs and Border Protection collects on goods found to benefit from foreign government subsidies, applied on top of the regular tariff rate. They exist to offset that subsidy-driven pricing edge. And in 2025, CVDs are actively reshaping landed costs across dozens of product categories.

Countervailing duties apply when foreign governments subsidize exports

Foreign government subsidies directed at specific producers or sectors can trigger countervailing duties on any product those producers export to the US. Not every government program counts. The legal test in 19 USC § 1677(5A) requires the subsidy to be "specific," meaning directed at identifiable companies, industries, or geographic zones.

Subsidies can take many forms. Direct cash grants. Below-market loans from state-owned banks. Tax breaks reserved for firms that export. Government-provided land at discounted rates. One case we worked through involved discounted electricity from a state utility feeding a single industrial park where every tenant was an export manufacturer. That qualified.

The April 2025 solar investigation broke new ground. Commerce traced subsidies from China's government flowing through factories in Cambodia, Malaysia, Thailand, and Vietnam. The plants sat in Southeast Asia. The funding came from Beijing. Commerce Secretary Howard Lutnick framed it as holding China accountable for "transnational subsidies through other countries." If you're sourcing from any factory backed by Chinese state financing, that precedent applies to your supply chain regardless of the factory's physical location.

The US CVD investigation process from petition to final order

From petition to final order, the CVD timeline runs about 10 to 14 months. What catches importers off guard: the financial exposure kicks in long before the case wraps up.

A domestic industry files the petition simultaneously with Commerce and the US International Trade Commission. Commerce has 20 days to decide whether to initiate. Most petitions clear that bar. From there, two agencies work in parallel. Commerce measures the subsidy. The ITC measures the injury. Both have to say yes. If either finds nothing, the case dies.

The moment that changes an importer's cash flow: Commerce's preliminary determination, 65 to 130 days after initiation. If affirmative, CBP suspends liquidation on every entry of the subject merchandise and starts collecting cash deposits at the estimated CVD rate. Those deposits can reach back retroactively up to 90 days before the preliminary determination. Goods that already cleared customs get a surprise bill.

Commerce's final determination follows 75 days later. The ITC issues its injury finding shortly after. Both affirmative? Commerce publishes the CVD order in the Federal Register, and the deposits become the new baseline.

Here's where import teams get burned. The preliminary rate is a rough estimate. Cambodia's preliminary solar CVD was 729%. Final rate: 3,400%. A customs broker we spoke with had three clients who built their Q1 2025 import budgets around the preliminary number. By April, the landed cost math on those shipments was upside down.

How CVD rates get calculated and applied to imports

The CVD rate an importer actually pays depends on the producer. Commerce assigns each investigated producer an individual rate based on the subsidies that producer received. Producers not individually examined get an "all others" rate. Producers who refuse to answer Commerce's questionnaires get hit with "adverse facts available," which means Commerce uses the worst available data. That 3,400% Cambodia rate? The producers didn't respond.

For any importer, the practical question is: how do I find the rate on my product? The answer is Commerce's ACCESS database (Antidumping and Countervailing Duty Centralized Electronic Service System at access.trade.gov). Every CVD order is filed there by case number, with the applicable HTS subheadings and producer-specific rates. Cross-referencing your HTS code lookup against ACCESS before placing a purchase order is the minimum check.

After a CVD order takes effect, importers post cash deposits with CBP on every entry. But the deposit is not the final number. During the anniversary month of the order, interested parties can request an administrative review. Commerce recalculates the actual subsidy for that period. Rate dropped? Refund. Went up? Bill plus interest, sometimes 18 months after the entry.

One trap that keeps catching people: a zero-percent cash deposit does not mean the goods are exempt. CBP's own AD/CVD FAQ spells this out. Zero just means the last review set the deposit at zero. If the next review finds new subsidies, the importer owes the full amount retroactively. We talked to one company that received a $340,000 duty bill on entries from a period where their deposit rate had been zero the entire time. The review caught a subsidy program Commerce hadn't identified in the original investigation.

Sunset reviews happen every 5 years. Commerce and the ITC evaluate whether revoking the order would bring subsidization back. Most orders survive. The CVD on Chinese solar cells has been active for over a decade, extended most recently in 2025.

CVD orders currently active on US imports

As of May 2025, the Commerce Department maintains 742 active AD and CVD orders. The growth trajectory matters more than the total. In fiscal year 2025, 91 new petitions hit across 27 industries. Broadest spread in a decade.

Look at the 2025 product range alone. Solar cells from Southeast Asia. Active anode material from China. Float glass from China and Malaysia. Oleoresin paprika from India. Steel reinforcing bar from Algeria and Egypt. Hardwood plywood from multiple Asian exporters. Van-type trailers from Canada and Mexico. Fresh mushrooms from Canada. Three years ago, half these products had zero AD/CVD history.

Running an HTS code lookup on a new product line without cross-checking active CVD orders is how import teams end up with CBP penalty notices. Every order ties to specific HTS subheadings, and CBP requires that case information on the entry summary. Miss it, and you face delayed liquidation. Worst case: doubled duties under the reimbursement presumption rule in 19 CFR 351.402. This customs compliance gap hits hardest when an established operation expands into a product it hasn't imported before, and nobody on the team realizes the HTS subheading carries an active order.

China holds the largest share of active CVD orders. But the geographic spread keeps growing. India, Vietnam, Indonesia, Cambodia, Malaysia, Canada, Mexico. No sourcing country sits outside US trade remedy jurisdiction.

Countervailing duties vs antidumping duties

Countervailing duties and antidumping duties often land on the same product from the same origin country, but they fix different problems. Antidumping duties go after pricing: a foreign producer selling in the US below home-market prices or below production costs. CVDs go after government action. The subsidy, not the exporter's pricing decision, is what Commerce measures.

A single product can carry both. The calculations run independently.

AD rates tend to be higher. In a prior anti-circumvention investigation on Chinese solar cells, the highest antidumping duty hit 238.95%. The corresponding CVD: 15.24%. Dumping margins capture the full pricing gap. CVD rates capture only the measured government subsidy.

One approach that consistently fails: assuming the AD duty already covers the subsidy. It doesn't. The two are separate line items on the entry summary. Commerce makes limited adjustments for overlap, but importers cannot offset one against the other.

Both duty types stack on top of normal tariffs. Solar panels entering the US in 2025 carry Section 201 tariffs at 14%, reciprocal tariffs, AD duties, and CVDs. Four separate layers on one shipment. Steel importers face a similar pile-up where Section 232 tariffs sit alongside AD/CVD orders. Chinese goods carry Section 301 tariffs on top of all of it. Without trade compliance software cross-referencing HTS subheadings against the current order list, the manual lookup eats hours every week for any mid-sized import operation.

FAQ

How long does a countervailing duty order last?

CVD orders stay in effect until Commerce and the ITC revoke them. Every 5 years, both agencies conduct a sunset review under Section 751(c) of the Tariff Act of 1930. If they determine that revoking the order would bring subsidization and injury back, the order continues. Most survive. Some have been active for over a decade.

Can an importer appeal a countervailing duty rate?

Importers can request an administrative review during the anniversary month of the CVD order. Commerce recalculates the rate using current-period data. Beyond that, Commerce or ITC determinations can be challenged before the US Court of International Trade, with further appeals to the US Court of Appeals for the Federal Circuit.

What happens if an importer fails to report AD/CVD information on an entry?

CBP requires the AD/CVD case number and applicable cash deposit on every entry summary for covered merchandise. Missing or inaccurate reporting triggers penalties and potential doubling of duties under 19 CFR 351.402 if CBP presumes the foreign producer reimbursed the duties.

Do countervailing duties apply to goods from US free trade agreement partners?

FTA status provides no exemption from countervailing duties. CVDs are imposed based on findings of subsidization and injury, not on trade agreement status. Canada and Mexico, both USMCA partners, have faced active CVD investigations on products like van-type trailers and fresh mushrooms in 2025.

What is the difference between customs import duties and countervailing duties?

Customs import duties are the baseline tariff rate on goods by HTS classification. Countervailing duties are an additional layer imposed after Commerce finds that foreign government subsidies benefited the producers. An importer pays both on covered merchandise.

The 742 active orders and 91 new petitions in fiscal year 2025 point in one direction. CVD exposure now covers product categories that carried no trade remedy history 3 years ago. For import operations still running HTS code lookups against the AD/CVD order list by hand, the workload breaks down past a few dozen entries per month. AI trade compliance platform flags active AD/CVD orders against HTS subheadings during product screening, before the goods leave the origin country, so the entry summary is correct on first filing and the duty bill holds no surprises.
