How to use

  1. Enter your declaration fields — at minimum Tax ID, HS code, regime, and country of origin.
  2. Click Validate. The checker flags errors against TT 38/2015 (as amended by TT 39/2018) and the MST check digit.
  3. Fix the error-level issues, then file through your VNACCS-certified software (e.g. ECUS).

This is a pre-check only. VNACCS remains the authority on acceptance. Lane assignment (green/yellow/red) is customs' internal risk engine and is not predicted here. For production filing, verify with a licensed customs broker.
