Conclusion: The EAC certification (the unified certification of the Eurasian Economic Union, required for export to Russia, Belarus, Kazakhstan, and the other two member states) has a reference lead time of 20–60 working days and a reference cost of RMB 8,000–40,000, depending on the product category and whether a factory audit is required. When a certificate is questioned during customs clearance, the common reasons are that the product description and model list on the certificate are inconsistent with the invoice, or that the certificate status has not been updated in the union's unified registration system. It is recommended to check in advance the consistency between the certificate attachments and the customs declaration documents, and to retain the test reports for reference. The Shuwang testing and certification platform can assist with pre-review of documents and coordinate with certification bodies to follow up on certificate status, reducing customs clearance delays.
EAC certification is based on technical regulations such as TR CU 004/2011 and 020/2011, and some products require sample testing and factory inspection. The certificate is valid for up to 5 years, but annual surveillance audits are required. During customs clearance, Russian customs will verify the certificate registration number. It is recommended that sellers verify the validity of the certificate through the union's official website before shipping.
