What is the difference between VOC and COI inspection certificates?
VOC跟COI认证的区别
They are basically same and follow the same documentary process with same documents. Normally we call it COI inspection when we inspect the cargo before loading and VOC inspection after pass Custom Clearance in the destination.
VOC 跟COI认证所需的文件以及文件流程基本一样，一般装柜前验货就是COI认证，目的地清关后验货则为VOC认证。
In connection with issuing VOC and COI certificates, the quality of the goods which is essential must be agreed by both parties and should be covered in the purchase documents. Observational tests check the conformity of materials and goods. The supplier and manufacturer should provide laboratory confirmation of compliance reports and the inspector should sign them. Once the process is completed, the VOC will be attached to the certificate.
在签发VOC跟COI证书过程中，产品以及产品材料的质量至关重要。买卖双方需认同货物的质量并且在合同内写明质量要求标准。一般我们会根据工厂提供的实验室测试报告以及标准证书进行测试，确认其质量以及性能。通常文件一致通过，VOC认证就会在第一时间签发。
