中国商务部同日发起两项反倾销调查：欧盟对位芳纶长丝与欧盟、日本乙叉降冰片烯被点名
北京——中国商务部11月6日同日宣布发起两项反倾销立案调查：一项针对原产于欧盟的进口对位芳纶长丝，另一项针对原产于欧盟和日本的进口乙叉降冰片烯。两项调查均应中国国内产业申请发起。
乙叉降冰片烯调查由商务部2026年第56号公告发布：商务部10月9日收到恒河材料科技股份有限公司代表中国乙叉降冰片烯产业提交的申请，倾销调查期为2025年7月1日至2026年6月30日，产业损害调查期为2023年1月1日至2026年6月30日。乙叉降冰片烯是合成三元乙丙橡胶的第三单体，可提升橡胶的硫化速度与交联密度，也用于合成树脂、塑料、弹性体与医药中间体，归入税则号列29021990。调查自11月6日起开始，通常应在2027年11月6日前结束，特殊情况下可延长6个月。
商务部新闻发言人答记者问时表示，申请人提供的初步证据显示：2023年至2026年上半年，自欧盟进口的对位芳纶长丝数量持续处于高位，价格累计跌幅超过50%；自欧盟等地区进口的乙叉降冰片烯数量2023年至2025年累计增长27.35%，2026年上半年同比增长56%，价格整体呈下降趋势。申请人主张上述倾销进口产品对中国国内产业的生产经营造成了损害，审查后两项申请均符合立案条件。对位芳纶是高强度合成纤维，广泛用于防弹防护、航空航天与光缆等领域。
发言人还指出，欧盟今年以来已对中国产品发起16起贸易救济调查，案件数量同比接近翻番，其中9起、近六成涉及化工产品；10月中旬以来，欧盟又接连对中国糠醇、聚偏二氟乙烯等产品发起反倾销调查。中方表示在贸易救济领域一贯审慎、克制，将根据中国法律和世贸组织规则开展调查、充分保障各利害关系方的权利并客观公正裁决，同时重申保护主义提升不了竞争力、通过对话协商解决关切才是正道。

China Opens Two Anti-Dumping Probes in One Day, Targeting EU Para-Aramid Yarns and EU and Japanese Ethylidene Norbornene
Beijing — China's Ministry of Commerce announced two new anti-dumping investigations on November 6: one into imports of para-aramid filament yarns from the European Union, and another into imports of ethylidene norbornene (ENB) from the European Union and Japan. Both were opened at the request of Chinese domestic industries.
The ENB probe was issued as the ministry's Announcement No. 56 of 2026. The ministry received the application on October 9 from Henghe Materials Technology Co. on behalf of China's ENB industry. The dumping investigation period runs from July 1, 2025 to June 30, 2026, and the injury period from January 1, 2023 to June 30, 2026. ENB is the third monomer used in EPDM rubber, where it raises curing speed and crosslink density, and is also used in synthetic resins, plastics, elastomers and pharmaceutical intermediates; it falls under tariff line 29021990. The investigation began on November 6 and is normally to conclude by November 6, 2027, extendable by six months in special circumstances.
A ministry spokesperson said preliminary evidence from the applicants showed that imports of para-aramid filament yarns from the EU remained at high volumes from 2023 through the first half of 2026 while prices fell by more than 50 percent cumulatively, and that ENB imports from the EU and other sources rose a cumulative 27.35 percent between 2023 and 2025 and 56 percent year on year in the first half of 2026, with prices trending down. The applicants allege the dumped imports injured China's domestic industries, and the ministry found both applications met the criteria for opening investigations. Para-aramid is a high-strength synthetic fiber used in body armor, aerospace and optical cables, among other applications.
The spokesperson also noted that the EU has opened 16 trade remedy investigations into Chinese products so far this year, nearly double the number in the same period last year, with nine of them — almost 60 percent — involving chemical products, and that since mid-October the bloc has launched further anti-dumping probes into Chinese furfuryl alcohol and polyvinylidene fluoride. China said it has consistently been prudent and restrained in trade remedies, would investigate in line with Chinese law and WTO rules, protect all parties' rights and rule objectively, and reiterated that protectionism does not improve competitiveness and that dialogue is the right way to address concerns.
