1. China’s Export Policy Conditions
Exporting 35kV oil-immersed transformers to the Middle East must first comply with China’s export management policies, including export licensing, inspection and quarantine, and tax incentives, which lay the foundation for legal export.
First, export licensing and filing. 35kV oil-immersed transformers belong to general mechanical and electrical products, and no special export license is required under normal circumstances. However, enterprises must complete export filing procedures with the relevant departments, truthfully declare product information such as model, specification, capacity, and IP rating, and ensure that the declared content is consistent with the actual product. For enterprises engaged in export business for the first time, they need to complete the record registration in the customs and foreign trade management systems to obtain the qualification for export operation.
Second, inspection and quarantine requirements. In accordance with the mandatory technical specification SN/T 1179.1-2007, all exported 35kV oil-immersed transformers must pass the inspection and quarantine by the entry-exit inspection and quarantine department (or designated third-party institutions) before export[2]. The inspection covers appearance quality, dimensional accuracy, performance indicators (insulation resistance, transformation ratio, DC resistance, etc.), and IP23 protection level verification. Only after passing the inspection and obtaining the inspection and quarantine certificate can the product be exported. For batch exports (more than 10 units), random sampling inspection shall be carried out in accordance with the standard, and full inspection shall be implemented for batches of less than 10 units to ensure product quality meets export requirements[2].
Third, export tax incentives. According to China’s export tax policies, 35kV oil-immersed transformers are included in the list of products eligible for value-added tax (VAT) refund (exemption)[4]. Eligible export enterprises can apply for VAT refund after completing export procedures, which helps reduce export costs and improve product competitiveness. The specific refund rate shall be implemented in accordance with the latest announcement of the State Taxation Administration, and enterprises need to provide complete export documents (customs declaration form, invoice, inspection certificate, etc.) to complete the refund application.
2. Middle East Import Access and Tariff Policies
Middle Eastern countries have relatively strict import access management for power equipment, and their tariff policies and import licensing requirements vary slightly, but there are common policy norms that need to be followed.
First, import licensing and filing. Most Middle Eastern countries (such as Saudi Arabia, the United Arab Emirates, and Kuwait) require foreign enterprises to complete import filing or obtain an import license before exporting power equipment. Enterprises need to provide product technical documents, certification reports, and enterprise qualification certificates to the local customs and relevant regulatory authorities for filing. For example, in the UAE, enterprises need to register with the Federal Customs Authority and provide product conformity documents to obtain import access qualifications[1].
Second, tariff policies. Tariff rates for 35kV oil-immersed transformers vary by country. Thanks to the China-UAE Comprehensive Economic Partnership Agreement (CEPA) which took effect on May 1, 2024, 35kV oil-immersed transformers exported from China to the UAE are included in the immediate zero-tariff category, which was previously subject to a 5% basic tariff of the Gulf Cooperation Council[1]. For other Middle Eastern countries (such as Saudi Arabia and Oman), the import tariff rate is generally 5%-10%. To enjoy preferential tariffs, products must meet the origin criteria of relevant trade agreements, such as the regional value content (RVC) not less than 40% for CEPA[1].
Third, pre-shipment inspection (PSI). Many Middle Eastern countries (including Saudi Arabia, Kuwait, and Qatar) require pre-shipment inspection for imported power equipment[3]. Enterprises need to entrust an internationally recognized inspection agency to conduct on-site inspection of the goods before shipment, including product quality, specifications, packaging, and labeling, and obtain a pre-shipment inspection certificate, which is a necessary document for customs clearance in the importing country.
3. IP23 Rating and Product Certification Policy Requirements
The IP23 rating is a key technical requirement for 35kV oil-immersed transformers exported to the Middle East, and its compliance must be supported by relevant certifications and test reports to meet local policy requirements.
First, IP23 rating compliance verification. The IP23 rating means that the transformer is protected against solid foreign objects with a diameter of more than 12.5mm and vertical dripping water. Middle Eastern countries require that exported transformers must provide a formal IP23 test report issued by a qualified third-party institution, proving that the product meets the requirements of the IEC 60529 standard (the international standard for protection levels). The test report must clearly indicate the test items, test methods, and test results, and be recognized by the importing country’s regulatory authorities.
Second, mandatory local certification. Middle Eastern countries have mandatory certification requirements for imported power equipment, and the specific certification types vary by country[3]. For example, Saudi Arabia requires products to obtain the SABER certification, which includes product conformity assessment and supplier qualification review; Kuwait requires the KUCAS certification, which combines pre-shipment inspection and product certification; the UAE requires products to comply with ESMA (Emirates Authority for Standardization and Metrology) standards and obtain relevant conformity certificates. These certifications must clearly indicate that the product meets the IP23 rating requirements and comply with local technical regulations.
Third, international standard compliance. In addition to local certification, 35kV oil-immersed transformers must also comply with international standards recognized by Middle Eastern countries, such as IEC 60076 (international standard for power transformers)[3]. The product’s technical parameters, performance indicators, and IP protection level must be consistent with the requirements of these international standards, and the relevant test reports must be provided to prove compliance.
4. Environmental and Safety Compliance Policies
Middle Eastern countries are increasingly paying attention to environmental protection and safety, and have formulated relevant policies and regulations for imported power equipment, which must be strictly followed by export enterprises.
First, environmental protection requirements. The insulation oil used in 35kV oil-immersed transformers must meet the environmental protection standards of the importing country, and must not contain harmful substances such as polychlorinated biphenyls (PCBs). Enterprises need to provide an insulation oil environmental protection test report to prove that the product meets the local environmental protection regulations. In addition, the packaging materials of the product must be environmentally friendly and recyclable, and must not cause environmental pollution.
Second, safety compliance requirements. The transformer must meet the local electrical safety standards, including insulation performance, short-circuit withstand capacity, and grounding protection. For example, the insulation resistance of the high-voltage winding to the low-voltage winding and ground must meet the requirements of SN/T 1179.1-2007, and the short-circuit withstand capacity must comply with IEC 60076 standards[2]. The product must be equipped with a complete safety protection device to avoid safety accidents during operation.
Third, labeling and documentation requirements. The transformer’s nameplate must be marked in both English and the local language (such as Arabic), clearly indicating the product model, rated parameters, IP rating, manufacturer information, production date, and certification marks[3]. In addition, complete technical documents (including product manual, test report, certification certificate, and origin certificate) must be provided, and the documents must be consistent with the actual product to avoid customs clearance risks.
5. Enterprise Qualification and Document Compliance
Export enterprises must have corresponding qualifications and ensure the completeness and authenticity of export documents to meet the policy requirements of both China and Middle Eastern countries.
First, enterprise qualification requirements. Export enterprises must have valid business licenses, export operation qualifications, and product production licenses (if required). For enterprises producing 35kV oil-immersed transformers, they must have a complete quality management system (such as ISO 9001 certification) to ensure stable product quality. Some Middle Eastern countries also require enterprises to provide supplier qualification certificates to prove their production capacity and product quality level.
Second, document compliance requirements. The key documents required for export include customs declaration form, commercial invoice, packing list, inspection and quarantine certificate, pre-shipment inspection certificate, product certification certificate, IP23 test report, origin certificate, and import license (if required). All documents must be true, complete, and consistent, and there must be no errors or inconsistencies to avoid being rejected by the local customs. For products enjoying preferential tariffs under CEPA, a formal China-UAE CEPA origin certificate must be provided[1].
Conclusion
Exporting 35kV oil-immersed transformers with IP23 rating to the Middle East involves multiple policy links, including China’s export management policies and the import access, certification, and tariff policies of Middle Eastern countries. Enterprises must strictly comply with the relevant policy conditions, including completing export filing and inspection and quarantine procedures, obtaining local mandatory certifications, ensuring IP23 rating compliance, and providing complete and authentic documents. By mastering these policy conditions, enterprises can effectively avoid trade risks, ensure smooth customs clearance, and improve the competitiveness of products in the Middle East market. With the continuous deepening of China’s economic and trade cooperation with Middle Eastern countries, especially the implementation of the China-UAE CEPA, the policy environment for export has become more favorable. Export enterprises should pay close attention to the policy changes of various Middle Eastern countries, strengthen technical and compliance management, and promote the healthy development of the export business of 35kV oil-immersed transformers.
