On May 21, 2026, the EU officially announced the implementing rules for the tariff preference scheme (GSP+) applicable to the United States. Although this policy is nominally aimed at the United States, its strengthened rules of origin and transit verification mechanism will materially affect Chinese chemical products exported to the EU market via third countries, especially creating systemic compliance pressure on export routes that rely on transit hubs such as Vietnam, Mexico, and Turkey.

Event Overview

On May 21, 2026, the European Commission officially issued the Guidelines on the Implementation of Rules of Origin Applicable to GSP+ Preferences for the United States (Commission Implementing Regulation (EU) 2026/XXX), clarifying that goods enjoying zero-tariff treatment must meet either the two origin criteria of “wholly obtained” or “substantial transformation”, and requiring customs to carry out enhanced origin verification on goods transshipped through third countries, including requiring importers to submit certified declarations of origin, production process traceability documents, and declarations from supply chain participants. These detailed rules will be implemented in phases starting from July 1, 2026, with the first phase focusing on the three major categories of chemicals, textiles, and metal products.

Which Sub-sectors Will Be Affected

Direct Trading Enterprises

For Chinese companies exporting chemical intermediates, functional additives, and custom synthetic chemicals to end customers in the EU under their own brands or through OEM arrangements, if the products are actually produced domestically but are declared as being of local origin after only simple relabeling, repacking, or packaging replacement in a third country, they will no longer qualify as “substantial transformation”. The direct impact will be reflected in customs clearance delays, retroactive recovery of tariff differentials from EU importers, and even return of entire shipments; some companies that have already signed long-term supply agreements may also trigger breach clauses under origin warranty provisions in their contracts.

Raw Material Procurement Enterprises

For Chinese traders that have established procurement centers in the EU and supply basic chemical raw materials (such as organic solvents, inorganic salts, and polymerization aids) to local formulation manufacturers, if their sourcing chain involves multi-layer transshipment or mixed origins (for example, goods purchased from domestic factories and then shipped from warehouses in Vietnam), it will be difficult for them to continuously provide EU buyers with compliant proof of origin. This may lead to procurement orders being reassessed, or force a switch to a higher-cost direct shipment model, thereby squeezing their original price competitiveness.

Processing and Manufacturing Enterprises

For Chinese chemical groups with assembly/blending plants in Southeast Asia and other regions, if they only perform low-value-added processes such as dilution, mixing, and filling on domestically produced semi-finished products, such operations are highly unlikely to constitute “substantial transformation” under the new rules, and their output products will not be able to claim GSP+ preferences. Such companies need to reassess the process depth of overseas plants, the proportion of local value-added, and records of R&D investment, otherwise they will lose their cost advantage in exports to Europe.

Supply Chain Service Enterprises

Third-party institutions providing international freight forwarding, agency services for certificates of origin, AEO certification consulting, and compliance audit services will face a surge in consulting and verification demand. However, it should be noted that the new rules clearly require declarations of origin to be signed by the exporter (rather than the freight forwarder) and for the exporter to bear legal responsibility, while EU customs has the right to directly access original production data. This means the traditional “document-handling agency” model will become ineffective, and service capabilities must be upgraded to full-chain traceability modeling and cross-jurisdictional compliance coordination.

Key Concerns and Response Measures for Relevant Enterprises or Practitioners

Immediately Conduct a Penetrating Audit of Rules of Origin Compliance for Existing Transshipment Routes

Cover the full-chain comparison from factory outbound records in China, operational details in transit countries (including storage duration, process descriptions, and equipment lists), to EU customs clearance documents, so as to identify whether there are risk points involving “false declarations of origin”, with particular attention to the matching between HS code classification and the corresponding origin criteria.

Distinguish the Legal Boundary Between “Transshipment Trade” and “Regional Value-added Production”

Avoid misjudging simple logistics transit as production capacity deployment. If the transit location has not undergone a tariff classification change, has not reached more than 45% local value-added, and lacks an independent quality control system, then claiming local origin is inadvisable; a more feasible path is to upgrade the transit-country factory into a substantial production base equipped with core processes such as reaction synthesis, purification, and refining.

Simultaneously Launch a Joint Compliance Response with EU Supply Chain Partners

Proactively disclose source information from China to EU importers and jointly prepare a Supply Chain Origin Transparency Memorandum, incorporating attachments such as production process flowcharts, key material BOM lists, and explanations of local value-added calculations, so as to establish a mutual trust mechanism in advance and reduce the commercial uncertainty caused by subsequent spot checks.

Assess the Rebalancing of Logistics and Costs Under a Direct Shipment Model

Compare the total cost of current transshipment routes (including potential supplementary duties, port detention, and losses from certification failure) with direct shipment solutions (longer shipping lead times and higher per-container costs), and combine this with order volume, product gross margin level, and customer stickiness to formulate a phased transportation strategy adjustment roadmap, thereby avoiding delivery disruptions caused by a “one-size-fits-all” switch.

Editorial Viewpoint / Industry Observation

显然，这项法规并不是针对中国出口的定向制裁，而是欧盟在更广泛贸易政策再校准背景下，对原产地执法进行的系统性收紧——在这一框架下，第三国转运被视为脆弱点，而非中性的物流选择。分析表明，真正的压力与其说来自关税税率本身，不如说来自如今加诸出口商的原产地举证负担：所要求的不只是文件声明，而是可核验的流程数据。从行业角度看，这一转变标志着合规模式正从“基于证书的合规”走向“基于流程的问责”。更值得关注的是，加拿大和日本也已在各自的GSP体系中讨论类似的原产地核查机制——这表明，它正在成为新兴的全球规范，而非欧盟的孤立举措。

Conclusion

The implementation of these EU rules of origin details marks that global chemical trade is entering a new stage of “verifiable origin”. For enterprises, compliance is no longer an isolated task for the legal department, but a systemic capability spanning R&D, procurement, production, logistics, and sales. More appropriately understood, this is not a threshold created by additional tariffs, but a comprehensive stress test of real control over the industrial chain. Only by internalizing origin management into the underlying logic of the supply chain can exporters maintain resilience in an environment of continuously tightening rules.
