注册Registration要求年产量超过1吨的所有现有***和新***及应用于各种产品中的化学物质注册其基本信息。只有通过注册的物质才能在欧盟内生产或进口。每一个物质的生产商和进口商须向化学管理署提交该物质的注册档案，并缴纳相应的费用。但是要求联合提交同一个物质的注册信息，即遵循“一个物质，一次注册”原则。作为联合注册的成员，可以与其他成员共同分摊注册的费用。为了易于管理、接受大量注册档案的提交，提交给化学署的注册档案需电子化处理。化学管理署会给每一个收到的注册档案一个注册编号和注册日期，并立刻把这些信息传递给注册人。在提交注册文档后的三周内，化学署会对提交的注册文档作一个完整性确认，以确定该档案符合REACH注册的要求。如果注册档案不完整，化学署将在注册提交之日起的三周内，通知注册人在规定的期限内提交进一步信息，把注册档案补充完整。对于分阶段物质，提供了预注册程序。通过预注册的物质，就可以继续在欧盟内生产和销售，只须在规定的***后期限前通过正式注册。对于分阶段物质，在期限内有大量的注册需要完成。因此，化学署对于每个提交的注册，需要在在3周内检查注册的资料是否完整；但是对于在截止日期前2个月内提交的每个注册，欧盟将在3个月内来检查注册是否完整。注册人需要在设定的期限内向化学署提交更新的档案，要求提交缺少的信息。然后化学署确定这些信息的提交日期，在3个星期内对更新的档案再进一步检查其完整性。如果注册人没在期限内能完成注册，注册将被化学署拒绝，制造商或进口商将不能开始或继续物质的制造或进口。如果有必要，化学署将会转送注册档案、注册号和日期、完整性检查的结果给成员国当局，制造商和进口商确立能够实施行动。为不完整的档案提交的补充信息，连同第二次完整性检查的结果提交给主管***。Alltheexisiting,newchemicalsubstancesitselfandwhichappliedtoeverymanufactureneedtoregistratebasicinformationwhentheoutputinquantitiesof1tonneormoreperyregisteredsubstancesareallowedtobemanufacturedorimported.EachmanufacturerorimporterofasubstanceshallsubmithisregistrationdossierforthesubstancetotheAgency,accompaniedbyafee.Buttheyshouldsubmittheinformationofthesamesubstancejointly,thatis”onesubject,oneregistration”.Asac***ortiummemberheonlyhastopayonethirdoftheregistrationfee.TheregistrationdossierssubmittedtotheAgencywillbehandledelectronicallytofacilitatethemanagementoftheexpectedamountofregistrati***thatwillbesubmitted.TheAgencyassignsaregistrationnumberandaregistrationdatetoeachregistrationdossierreceivedandimmediatelycommunicatesthisinformationtotheregistrant.Within3weeksoftheregistrationdate,theAgencyperformsanautomatedcompletenesscheckofthedossiertoascertainthatallelementsrequiredfortheregistrationareincluded.Iftheregistrationisincomplete,theAgencywillinformtheregistrantwithinthese3weeksfromtheregistrationdateaboutwhichfurtherinformationisneededandwillsetadeadlineforcompletionofthedossier.Forphase-insubstances,ac***iderablenumberofregistrati***areexpectedtoarrivejustbeforethedeadlinesfortheregistrati***.Therefore,theAgencyisgiven3monthsfromeachregistrationdeadlinetocheckthecompletenessofthoseregistrati***thath***ebeensubmittedwithin2monthsofthedeadlines.However,theAgencywillh***etocheckthecompletenessofregistrati***submittedmorethan2monthsbeforethedeadlines,within3weeksofreceipt.TheregistrantneedstosubmittherequestedmissinginformationinanupdateddossiertotheAgencywithinthesetdeadline.TheAgencythenconfirmsthesubmissiondateofthisinformationandmakesafurthercompletenesscheckwithin3weeksofreceiptoftheupdateddossier.Iftheregistrantfailstocompletehisregistrationwithinthesetdeadline,theregistrationwillberejectedbytheAgencyandthemanufacturerorimporterisnotallowedtostartorcontinuemanufactureorimportofthesubstance.TheAgencywillforwardtheregistrationdossier,theregistrationnumberanddate,andtheresultofthecompletenesschecktotheauthoritiesoftheMemberStatesinwhichthemanufacturersandimportersareestablishedtoenableenforcementaction,ifnecessary.Alsothefurtherinformationthatissubmittedforcompletionofthedossierwillbeforwardedtothecompetentauthoritytogetherwiththeresultofthesecondcompletenesscheck.)
