On 17 October 2025, the Ministry of Commerce (MOFCOM) received an expiry-review application submitted by Jilin Petrochemical Company of CNPC and Shanghai Sinopec Mitsui Elastomers Co., Ltd. (hereinafter referred to as the "Applicants") on behalf of the domestic ethylene-propylene-diene monomer (EPDM) rubber industry. The Applicants contend that, should the anti-dumping measures be terminated, dumping of EPDM rubber originating in the United States, South Korea and the European Union is likely to continue or recur, and injury to the domestic industry is likewise likely to continue or recur. They therefore request that MOFCOM initiate an expiry-review investigation into the anti-dumping measures applicable to such imports and maintain the measures. No expiry-review application was filed with respect to EPDM rubber originating in the United Kingdom.

        Pursuant to Article 48 of the Anti-Dumping Regulations of the People's Republic of China, MOFCOM has decided, as of 20 December 2025, to open an expiry-review investigation into the anti-dumping measures on EPDM rubber originating in the United States, South Korea and the European Union. The matter is hereby announced s follows:

  Continuation of the anti-dumping measures  

       Upon MOFCOM's recommendation, the Customs Tariff Commission of the State Council has decided that, during the expiry-review investigation, the anti-dumping duties shall continue to be imposed on EPDM rubber originating in the United States, South Korea and the European Union at the rates and within the scope set out in MOFCOM Announcement No. 60 of 2020. The anti-dumping measures applicable to EPDM rubber originating in the United Kingdom will expire and be terminated on 20 December 2025.

The anti-dumping duty rates imposed on each company are as follows:

U.S. companies

1、The Dow Chemical Company   （ 222.0%）
2、Exxon Mobil Corporation         （214.9%）
3、ARLANXEO USA LLC                 （219.8%）
4、Lion Copolymer Geismar,LLC    （219.8%）
5、Other U.S. companies               （222.0%）

South Korean companies

1、KUMHO POLYCHEM Co.,Ltd.           （12.5%）
2、Lotte Versalis Elastomers Co.,Ltd.    （21.1%）
3、Other South Korean companies       （24.5%）

European Union companies
1、ARLANXEO Netherlands B.V.ARLANXEO Netherlands B.V.     （18.1%）

  Product Scope Under Review  

        The product scope is identical to that covered by the original anti-dumping measures announced in MOFCOM Notice No. 60 of 2020, namely:

       English name: Ethylene-Propylene-non-conjugated Diene Rubber或Ethylene Propylene Diene Monomer（EPDM）

       Physico-chemical characteristics: EPDM is a terpolymer of ethylene, propylene and a non-conjugated diene. At room temperature it appears as a white to light-yellow solid that is easy to mix. Its physical, chemical and processing properties vary with molecular structure, which in turn is determined by the type of third monomer, Mooney viscosity, oil-extension level, etc. EPDM offers good ageing, chemical, low-temperature and dielectric properties.

       Main uses: EPDM is used widely in construction, wire & cable, automotive and transportation sectors.Construction，single-ply roofing membranes, etc. Wire & cable: power-feed lines for civil and commercial buildings, construction-machine cables, mining cables, nuclear-plant cables, automotive ignition wires, control & signal cables, etc. Automotive: non-tyre parts for cars, trucks and buses—radiator and heat-resistant hoses, sealing strips, rubber belts, body & chassis parts, rain strips, floor mats, grommets, etc. Transportation: door/window seals, anti-vibration pads, water-stop strips, etc.

       The product is classified under China’s Customs Import & Export Tariff headings 40027010 and 40027090.

Issues to be Reviewed
       Whether the expiry of the anti-dumping measures on EPDM rubber originating in the United States, South Korea and the European Union is likely to lead to the continuation or recurrence of dumping and injury.

  Time-limit for the Investigation  

       The investigation begins on 20 December 2025 and must be completed by 20 December 2026 (excluding the date of issuance).
