EAC CoC vs EAC DoC Full Comparative Guide (2026 Official EAEU Rules)
Both documents carry equal legal validity for customs clearance & sales across all 5 EAEU nations (RU/BY/KZ/KG/AM). The applicable type is strictly defined by the corresponding TR CU technical regulation — you cannot choose freely.
