2. On-site factory quality audit to verify consistent production control

3. Document review of your full technical dossier

4. Issuance + registration into FGIS

5. Annual surveillance audit + periodic sample retesting during certificate validity (1–5 years)

• Scheme 3C (batch certificate):

1. Sample testing only

2. No factory audit

3. Valid only for the specified shipment batch quantity, no annual surveillance

• Scheme 4C: for single unique equipment / project machinery

3. Legal rights the certificate gives you

1. Goods can be imported, cleared by customs and freely circulated across all five EAEU countries (no separate national certification required)
