我国有机原料及中间体行业在国际贸易中面临的形势与对策

我国是亚洲有机中间体生产国家中最具影响力和竞争力的国家，但最近几年我国遭遇了越来越多的针对化工产品的反倾销指控和各种壁垒障碍等，严重影响了我国的外贸出口。本文分析了反倾销案发生的特点及原因，重点分析了几种重要产品的进出口形势，并对在反倾销应诉和申诉过程中如何更好地维护自身利益提出了建议。

印度启动炭黑反倾销期中复审

日前,印度商工部决定对原产于中国、澳大利亚、俄罗斯和泰国的橡胶用炭黑启动反倾销期中复审。印度商工部将根据复审中各方提交的资料重新计算各应诉企业的倾销幅度和损害程度,据此重新裁定各应诉企业的反倾销税率和未应诉企业的反倾销税率。倾销调查期为2010年4月1日至2011年3月31日,损害调查期为2007年4月1日至2011年3月31日。

2005年化工产品贸易摩擦大事记（一）

中国加入世界贸易组织(WTO)后,对外贸易迅速增长,世界排名仅次于美国和德国上升至第三位,但由于部分国家和地区滥用反倾销措施,使中国成为最大的受害者。1995-2005年,中国已连续10年成为世界反倾销头号目标国,共遭受反倾销390起。本文汇集了2005年中国化工领域遭遇的反倾销案件,以及中国对国外化工产品进行的反倾销诉讼。     

美可能对我国聚四氟乙烯进行反倾销立案调查

据中国五矿化工进出口商会报道，美国很可能对我输美聚四氟乙烯（PTFE）进行反倾销立案调查。 2005年12月8日，美国国际贸易委员会对原产于意大利和日本的聚四氟乙烯的反倾销日落复审投票后决定，继续实施反倾销措施。该起反倾销案件的申诉方是杜邦公司（E．I DuPont）。     

政策要闻

我国在阿根廷草甘膦反倾销案中获胜据报道,阿根廷政府4日宣布,终止对华草甘膦反倾销调查,不征收反倾销税。组织该案应诉的中国五矿化工进出口商会认为,四位一体的反倾销应诉机制对胜诉的结果起到了积极的作用。草甘膦是我国农药行业单项出口最大的产品。我国生产的草甘膦约有80%用于出口,阿根廷则是我国草甘膦出口的最大市场。根据海关统计,2002年,阿根廷市场占我国草甘膦出口总量的33%。在长达近两年的反倾销调查期内,我出口草甘膦的涉案金额达5800万美元。可以说,该反倾销案的胜诉对我国草甘膦生产、出口企业意义非同一般。五矿商会石化部…     

美国商务部重新确定轮胎双反调查强制应诉企业

10月6日，美国对华轮胎反倾销反补贴调查中的强制应诉企业山东永盛橡胶集团有限公司决定退出应诉。鉴于此，10月7日，美国商务部分别重新确定了反倾销和反补贴调查的强制应诉企业。     

用“反倾销”武器保护自己

用“反倾销”武器保护自己自８０年代末以来，欧洲、美国、日本的企业频频在其本国对我国提出“反倾销”诉讼，而我国企业界起而应诉者甚少，致使市场拱手交还他人，退出该国市场。近年来，在我国市场上，我国企业界的行为似乎又更为“礼让”。国外某些大公司，为获得我国...     

Insect antifeedant properties of anthranoids from the genusVismia

Direct observation of freeze-thaw instability of latex coatings via high pressure freezing and cryogenic SEM

Despite its industrial importance, the subject of freeze-thaw (F/T) stability of latex coatings has not been studied extensively. There is also a lack of fundamental understanding about the process and the mechanisms through which a coating becomes destabilized. High pressure (2100 bar) freezing fixes the state of water-suspended particles of polymer binder and inorganic pigments without the growth of ice crystals during freezing that produce artifacts in direct imaging scanning electron microscopy (SEM) of fracture surfaces of frozen coatings. We show that by incorporating copolymerizable functional monomers, it is possible to achieve F/T stability in polymer latexes and in low-VOC paints, as judged by the microstructures revealed by the cryogenic SEM technique. Particle coalescence as well as pigment segregation in F/T unstable systems are visualized. In order to achieve F/T stability in paints, latex particles must not flocculate and should provide protection to inorganic pigment and extender particles. Because of the unique capabilities of the cryogenic SEM, we are able to separate the effects of freezing and thawing, and study the influence of the rate of freezing and thawing on F/T stability. Destabilization can be caused by either freezing or thawing. A slow freezing process is more detrimental to F/T stability than a fast freezing process; the latter actually preserves suspension stability during freezing.

Gordon Best Paper Competition.     

Ethanol and (−)-α-Pinene: Attractant Kairomones for Bark and Ambrosia Beetles in the Southeastern US

In 2002–2004, we examined the flight responses of 49 species of native and exotic bark and ambrosia beetles (Coleoptera: Scolytidae and Platypodidae) to traps baited with ethanol and/or (−)-α-pinene in the southeastern US. Eight field trials were conducted in mature pine stands in Alabama, Florida, Georgia, North Carolina, and South Carolina. Funnel traps baited with ethanol lures (release rate, about 0.6 g/day at 25–28°C) were attractive to ten species of ambrosia beetles (Ambrosiodmus tachygraphus, Anisandrus sayi, Dryoxylon onoharaensum, Monarthrum mali, Xyleborinus saxesenii, Xyleborus affinis, Xyleborus ferrugineus, Xylosandrus compactus, Xylosandrus crassiusculus, and Xylosandrus germanus) and two species of bark beetles (Cryptocarenus heveae and Hypothenemus sp.). Traps baited with (−)-α-pinene lures (release rate, 2–6 g/day at 25–28°C) were attractive to five bark beetle species (Dendroctonus terebrans, Hylastes porculus, Hylastes salebrosus, Hylastes tenuis, and Ips grandicollis) and one platypodid ambrosia beetle species (Myoplatypus flavicornis). Ethanol enhanced responses of some species (Xyleborus pubescens, H. porculus, H. salebrosus, H. tenuis, and Pityophthorus cariniceps) to traps baited with (−)-α-pinene in some locations. (−)-α-Pinene interrupted the response of some ambrosia beetle species to traps baited with ethanol, but only the response of D. onoharaensum was interrupted consistently at most locations. Of 23 species of ambrosia beetles captured in our field trials, nine were exotic and accounted for 70–97% of total catches of ambrosia beetles. Our results provide support for the continued use of separate traps baited with ethanol alone and ethanol with (−)-α-pinene to detect and monitor common bark and ambrosia beetles from the southeastern region of the US.     

Methyl 2,4,6-decatrienoates Attract Stink Bugs and Tachinid Parasitoids

Halyomorpha halys (Stål) (Pentatomidae), called the brown marmorated stink bug (BMSB), is a newly invasive species in the eastern USA that is rapidly spreading from the original point of establishment in Allentown, PA. In its native range, the BMSB is reportedly attracted to methyl (E,E,Z)-2,4,6-decatrienoate, the male-produced pheromone of another pentatomid common in eastern Asia, Plautia stali Scott. In North America, Thyanta spp. are the only pentatomids known to produce methyl 2,4,6-decatrienoate [the (E,Z,Z)-isomer] as part of their pheromones. Methyl 2,4,6-decatrienoates were field-tested in Maryland to monitor the spread of the BMSB and to explore the possibility that Thyanta spp. are an alternate host for parasitic tachinid flies that use stink bug pheromones as host-finding kairomones. Here we report the first captures of adult and nymph BMSBs in traps baited with methyl (E,E,Z)-2,4,6-decatrienoate in central Maryland and present data verifying that the tachinid, Euclytia flava (Townsend), exploits methyl (E,Z,Z)-2,4,6-decatrienoate as a kairomone. We also report the unexpected finding that various isomers of methyl 2,4,6-decatrienoate attract Acrosternum hilare (Say), although this bug apparently does not produce methyl decatrienoates. Other stink bugs and tachinids native to North America were also attracted to methyl 2,4,6-decatrienoates. These data indicate there are Heteroptera in North America in addition to Thyanta spp. that probably use methyl 2,4,6-decatrienoates as pheromones. The evidence that some pentatomids exploit the pheromones of other true bugs as kairomones to find food or to congregate as a passive defense against tachinid parasitism is discussed.
