• Flag State: Must ensure compliance via inspections, issue Maritime Labour Certificate (≤5 years), require intermediate inspection between 2nd-3rd anniversary, and maintain DMLC Part I (national requirements) & Part II (shipowner measures).
• Port State: Accepts certificate/DMLC as prima facie evidence; may conduct detailed inspection if documents are invalid, conditions non-conforming, or complaints exist.
• Detention: Ship may be detained if conditions are hazardous or non-conformity is serious/repeated (Std A5.2.1.6).
• Trap: Certificate ceases validity if inspections not completed or ship changes flag.
