Direct Integration with the DGA's SIGA

We are not a form that copies data. We are a certified API connection to the Customs system.

With aduanasHQ + SIGA

How it actually works

  • Step 1: Enter data once in aduanasHQ
  • Step 2: P4 validates RNC/Cédula and SIGA rules (before submitting)
  • Step 3: Click "Submit" → Automatic transmission via API
  • Step 4: SIGA responds in 5-10 seconds (accepted/rejected)
  • Step 5: P4 shows real-time status
Result: 10 minutes on average per DUA vs. 50 minutes manually

Manual Process (SIGA Portal)

What you do now

  • Log into the SIGA portal (with a security token)
  • Copy invoice/packing list data manually
  • Validate RNC/Cédula manually, one by one
  • Look up tariff codes one by one
  • Wait for validation (can take minutes if SIGA is slow)
  • If there's an error: go back, fix it, resubmit
Problems: Typing errors, invalid RNCs, rejected declarations, wasted time
