俄罗斯采购需求：中国物流公司，中国仓储服务，食品出口，服装出口，医疗设备出口，中国清关

I'm looking for detailed guidance on how to register the Russian Carnet ATA within the CCPIT system. Specifically, I would appreciate any step-by-step instructions or requirements that need to be met during the registration process. Additionally, if you could provide me with the direct link to the relevant registration portal or any official resources, it would be extremely helpful. Your assistance in this matter is much appreciated!
