On September 29, 2026, the U.S. Department of Commerce announced an affirmative preliminary countervailing duty determination on fixed and portable air compressors from China, Malaysia and Vietnam. On the same day, the Directorate General of Trade Remedies of India initiated anti-dumping and countervailing investigations, respectively, into internally threaded copper tubes from China, Thailand and Vietnam.

The two sets of cases involve different products and jurisdictions, and are at different procedural stages: the U.S. case is only a preliminary determination, and the Indian cases are only initiations; neither amounts to a final conclusion on duty imposition. But viewed together, they send a signal of greater value to Chinese enterprises going global: trade remedy investigations are simultaneously examining Chinese and Southeast Asian production capacity along cross-border supply chains. It is no longer sufficient for an enterprise to prove only that "the goods are produced in Vietnam, Thailand or Malaysia"; that does not answer the investigating authorities' follow-up questions on subsidies, pricing, related-party transactions and government support.

I. What the latest developments show

The preliminary determination published by the U.S. Department of Commerce shows a preliminary subsidy rate of 3.84% for the Chinese mandatory respondent FNA (Zhejiang) Co., Ltd.; several other named Chinese enterprises were assigned a preliminary rate of 112.29% because facts available with an adverse inference were applied; the rate for all other Chinese enterprises is 3.84%. The preliminary rate for the named Malaysian enterprises and "all others" is 92.86%, while Vietnamese enterprises received differing results of 0.35%, 37.20% and 74.39%. The U.S. Department of Commerce also stated that the final countervailing duty determination will be aligned with the final determination in the companion anti-dumping investigation, currently expected to be published on February 11, 2027, unless postponed. The U.S. International Trade Commission had previously made a preliminary finding of a reasonable indication that the subject imports materially injure or threaten material injury to the domestic industry of the United States.

These figures are, first of all, procedural results, not final findings that the enterprises violated the law. In particular, the official statement expressly explains that the high rates marked with an asterisk are based on "facts available with an adverse inference." This shows that the actual duty risk arises not only from what support an enterprise received, but also from whether the enterprise can respond to questionnaires and supplemental questions on time, completely and consistently.

The Indian cases better reflect the trend of parallel review of cross-border production capacity. The Directorate General of Trade Remedies of India initiated investigations under Case No. 6/53/2026-DGTR and Case No. 6/54/2026-DGTR, respectively, examining dumping and subsidies at the same time with respect to the same type of internally threaded copper tubes from China, Thailand and Vietnam. Anti-dumping focuses on export prices and normal value, while countervailing focuses on financial support attributable to a government or public body that confers a benefit on a specific enterprise or industry. The two tracks may proceed on the basis of the same set of procurement, production, financing and sales materials, but their legal elements and the focus of the defense are not the same.

II. Why Southeast Asian production capacity cannot inherently insulate against countervailing duty risk

Rules of origin, anti-circumvention and countervailing measures are often conflated into a single issue within an enterprise. In fact, they answer three different questions.

Rules of origin determine which country goods should be attributed to; anti-circumvention review examines whether processing in a third country is circumventing existing trade remedy measures; countervailing review examines whether production and export are supported by government support against which countermeasures may be taken. Even if a product obtains Vietnamese or Thai origin through genuine and sufficient manufacturing activities, that does not mean the local factory has not received preferences for land, tax, financing, energy or industrial parks, still less does it mean that equipment, raw materials, guarantees and funding arrangements provided by the Chinese parent company will not be questioned by the investigating authority.

For enterprises going global, what really needs to be drawn is not a "certificate-of-origin roadmap," but four interlocking maps: a map of legal persons and control relationships, a map of manufacturing and procurement, a map of funds and guarantees, and a map of government support. The investigating authority may issue questionnaires to exporters, producers, related parties and relevant governments respectively, and conduct cross-verification through customs data, corporate annual reports, bank materials and public policies.

This is also why "the local company is independently registered," "there are factory buildings and equipment locally" and "the product has obtained a certificate of origin" can prove only part of the facts. The countervailing analysis will continue to ask: how was the land use right obtained, and was the price below an appropriate benchmark; whether loans, insurance, export credit and parent company guarantees provided measurable benefits; whether income tax reductions and exemptions, duty-free import of equipment and industrial park rebates are specific; whether electricity, natural gas or raw materials are provided by government-controlled entities on preferential terms; and whether transactions in equipment, raw materials and technology between the Chinese related parties and the Southeast Asian factory are on normal commercial terms.

III. The biggest risk is often not “having received subsidies,” but being unable to explain where the money came from

Many companies understand a subsidy as a sum of cash paid directly into an account by the government. In trade remedies, the concepts of “financial contribution” and “benefit” are usually broader and may cover direct grants, tax reductions or exemptions, preferential loans, loan guarantees, the provision of goods or services by the government, and government purchases of goods. Whether a particular measure constitutes a countervailable subsidy must still be determined in light of the law of the investigating country, the specificity of the program, the calculation of benefit and the attribution standards; one cannot simply conclude that a subsidy exists merely because a preference is present.

In responding to an investigation, however, evidentiary gaps themselves magnify risk. In the preliminary determination in the US air compressor case, the enormous differences in the rates applied to different companies serve at least as a reminder of the consequences of “adverse inferences”: where the investigating authority considers that necessary information was not provided, that responses cannot be verified, or that a party has failed to cooperate to the best of its ability, it may use other information on the record and make adverse choices. The final rates may of course still change, but companies cannot treat a response as an ordinary round of document submission.

Common gaps include: group financing arranged centrally by headquarters, with overseas factories unable to explain the actual cost of funds; bank loans nominally obtained by a local subsidiary but guaranteed or secured by deposits from the Chinese parent company; equipment transferred by related parties free of charge or at low prices, with no complete pricing basis on the books; industrial parks building factories, refunding rent or bearing infrastructure costs on the company’s behalf, while the contracts and accounting treatment are scattered; tax preferences stated in tax returns, while the legal and export teams do not know the basis on which they apply; and raw materials purchased through related trading companies, with the manufacturing enterprise unable to trace through to the suppliers and the pricing.

These issues do not necessarily mean that the company has of course received a countervailable benefit, but they make it difficult for the company to prove the contrary. The core capability in trade remedies is not merely to advance legal arguments, but to make contracts, bank records, accounting, tax, customs, production capacity and group decision-making records tell the same story.

IV. Law × Finance × Risk × Transaction × Geopolitics: How to approach such cases

From a legal perspective, companies should first distinguish among initiation, preliminary determination, final determination and the assessment order, and should not mistake a preliminary rate for a final liability; at the same time, they should confirm the product scope, the period of investigation, the response deadlines, the sampling rules and the related-party disclosure requirements. Missing a registration or questionnaire deadline often leaves a company in a very passive position when it later seeks to supplement information.

From a financial perspective, a subsidy investigation is in essence a re-pricing of the company’s cost of capital and cost of public resources. Loan interest rates, guarantee fees, land prices, energy prices, tax burdens and government grants may all be converted into a benefit per unit of product and ultimately feed into the duty rate. The CFO cannot leave the forms to the foreign trade department alone, but should take the lead in reconstructing the financing, guarantees and tax preferences.

From a risk perspective, companies should model three scenarios at the same time: no provisional measures, duties at the individual rate, and duties at a high adverse-inference rate. The modeling should not look only at tariffs, but should also incorporate cash deposits, retroactive adjustments, customer claims, inventory write-downs, tightening of credit lines and order diversion.

From a transactional perspective, contracts need to specify the obligations to cooperate during the investigation, data provision, price adjustments, allocation of tax burdens and termination mechanisms. If the importer holds the US or Indian filing materials and the exporter holds the cost and subsidy materials, and the parties have no cooperation clause, key evidence can easily break down.

From a geopolitical perspective, cases covering both China and Southeast Asia show that regulators increasingly decline to treat supply chain relocation as a simple binary switch between “made in China” and “made in Southeast Asia.” Industrial policy, the source of capital, dependence on equipment and raw materials, regional capacity expansion and injury to the ultimate market are being placed within the same analytical framework. A Southeast Asian footprint still has commercial value, but that value should come from genuine production efficiency, proximity to markets and supply chain resilience, rather than from an assumed insulation from trade remedy risk.

V. Companies should build a “subsidy evidence chain”

First, establish a government support ledger organized by 'legal entity—factory—project—year.' Record item by item the basis for the application, approval documents, amounts, accounting entries, conditions of use, beneficiary entities, and whether the support is tied to exports or production volume. Even for projects that did not receive support, retain verification working papers; do not simply write 'none.'

Second, trace the funding paths through to the final cost. For bank loans, shareholder loans, guarantees, letters of credit, export insurance, factoring, and equipment financing, explain transaction by transaction the source of funds, pricing benchmark, guarantee structure, and actual use. For group cash pools or cross-border cash-pooling arrangements in particular, distinguish who is the borrower, who bears the cost, and who actually uses the funds.

Third, review related-party transactions. When a Chinese parent company provides equipment, raw materials, technology, trademarks, management services, or financing to a Southeast Asian subsidiary, it should retain the pricing methodology, comparable transactions, payment records, and board authorization. Countervailing duty, anti-dumping, transfer pricing, and customs valuation proceedings may examine the same transaction from different angles, and the positions taken must not conflict with one another.

Fourth, prepare questionnaire-grade data in advance. Sales, costs, production volume, procurement, inventory, government support, and related-party information should be traceable from the general ledger to the original vouchers and reconcilable with customs and tax filings. If hastily assembled spreadsheets cannot be recalculated and version differences cannot be explained, credibility will be lost quickly during the verification stage.

Fifth, incorporate the timetable into the crisis response plan. Upon receiving notice of an investigation, immediately complete the preliminary screening of the product scope, confirmation of related parties, decisions on which entities should respond, and preservation of documents; for decisions on whether to apply for a separate rate, participate in sampling, submit injury defenses, and coordinate actions with industry associations, assign responsible persons and deadlines.

VI. How This Article Differs from Origin Compliance

The website has previously discussed 'how to determine U.S. origin after moving the supply chain to Southeast Asia.' The core of that question is substantial transformation, tariff classification, production processes, and consistency of declarations. This article addresses a different level: even if Southeast Asian origin is established, a company may still face countervailing measures because of local or cross-border government support, related-party financing, and failure to cooperate in providing information.

Therefore, the origin evidence chain and the subsidy evidence chain must proceed in parallel. The former answers where the product acquires its economic nationality; the latter answers whether the production cost contains government support that is attributable, specific, and confers a benefit on the company. The two share BOM, process, and procurement materials, but they cannot substitute for each other.

Conclusion

The preliminary determination in the U.S. air compressor case and the initiation of the anti-dumping and countervailing duty investigation into Indian internally threaded copper tubes have not yet reached final conclusions, and it would be inappropriate to assert on that basis that any company has already violated the law or will necessarily bear a particular duty rate. They are nonetheless sufficient to remind management that as Chinese companies extend their production capacity, financing, and procurement networks into Southeast Asia, trade remedy risks will extend along the same networks.

'Where to produce' is only the first question. The harder second question is: under what conditions do land, equipment, raw materials, energy, and funds enter the factory, who provides the preferences, who receives the benefits, and can the company explain this with continuous, verifiable materials. Building this set of questions into an evidence chain at the time the investment is implemented is far more valuable than hastily supplementing materials after receiving an investigation questionnaire.
