我国公民要去国外学习、工作、居住，或是在国内办理出国签证时，通常需要使用某些国内公证处出具的涉外公证书，如出生公证、未受刑事处分公证、授权委托书公证、合同公证等等。这些公证书在送国外使用前可能需要办理领事认证；企业因境外经贸活动需要，常需向贸促会申请原产地证、发票、装箱单等，或向出入境检验检疫机构申请原产地证明、动植物出口检疫证明书等,上述文书在发往国外使用前，可能需办理领事认证。
通常公民个人或企业出国办理事务或进行企业活动，外国驻华使领馆或该国的有关部门会向当事人提出文书领事认证要求。如果对方要求您办理领事认证，那么您应当按对方的要求准备相应的文书。

When Chinese citizens want to study, work, live abroad, or apply for visas abroad in China, they usually need to use some foreign-related notarization certificates issued by domestic notary offices, such as birth notarization, notarization without criminal punishment, notarization of power of attorney, contract notarization, etc. These notarizations may need to be certified before they are sent to foreign countries for use; Enterprises often need to apply to CCPIT for certificates of origin, invoices, packing lists, etc., or to the exit-entry inspection and quarantine agency for certificates of origin, animal and plant export quarantine certificates, etc. due to overseas economic and trade activities, and the above documents may need to apply for consular certification before they are sent to foreign countries for use.

Ordinarily, citizens or enterprises go abroad to handle affairs or carry out enterprise activities, and foreign embassies and consulates in China or relevant departments of that country will put forward document consular certification requirements to the parties concerned. In case the other party requires you to apply for consular certification, you should prepare the corresponding documents as required by the other party.
