When you need a legalised certificate of analysis in China
A certificate of analysis (COA) reports the test results for a batch of product against its specification. Regulators and buyers abroad use it to check quality for registration samples, tenders and each consignment. The certificate of analysis is issued by the manufacturer's quality control department or an accredited testing laboratory for a specific batch.
Drug regulators across South-East and South Asia register many Indian medicines and typically ask for the regulatory certificates in a legalised form.
In China, pharmaceutical dossiers are reviewed by the National Medical Products Administration (NMPA). Legalised documents from India are typically part of the file for registration samples for regulators, batch release for each shipment and tender quality compliance.
A certificate of analysis issued in India is attested by an Indian Chamber of Commerce, then by the Ministry of External Affairs (MEA), and finally legalised by the Embassy of China in New Delhi.
Although China joined the Apostille Convention in 2023, in our processing experience Indian commercial documents for China are still legalised through the Chinese Embassy, so that is the route we follow.
