通常需要认证文件有：invoice，装箱单、报关单、合同、授权书、营业执照、销售证书等等LETTER OF AUTHORIZATIONA授权委托书认证 印尼大使馆加签

LOA是什么文件呢？为什么印尼买家要求LOA要做印尼大使馆认证呢？

您好， LOA是授权书，英文全称叫 APPOINTMENT LETTER，这是出口到印尼这个国家的时候，印尼买家，进口商那边要求中国出口商填写好后盖章出具给他们的一份文件，这份文件还要求要做印尼在中国的大使馆加签，简称是LOA证书大使馆认证；

LOA的内容有固定，一般印尼进口商们会提供APPOINTMENT LETTER的格式，按照格式填写好信息之后打印出来盖章签名就可以了，如果没有提供格式的话，也可以联系我司，我司可以提供格式给您参考；

怎么办理APPOINTMENT LETTER印尼大使馆认证呢？

答：如果需要办理APPOINTMENT LETTER使馆认证的话，首先是先准备好文件，先将APPOINTMENT LETTER填写好，然后打印出来，盖章签名之后加营业执照复印件一份，以及一份给印尼大使馆的保函，也是打印盖章就可以了，然后将这些文件邮寄给我司，我司收到文件之后会帮您安排送印尼大使馆进行认证加签，认证完毕之后会将文件邮寄给您；
