With aduanasHQ + DUAE

How it really works

  • Step 1: Enter data once in aduanasHQ
  • Step 2: P4 validates against DUAE rules (before submitting)
  • Step 3: Click "Submit" → Automatic transmission via API
  • Step 4: DUAE responds in 8-15 seconds (accepted/rejected)
  • Step 5: P4 displays status in real time

Manual Process (DUAE Portal)

What you do now

  • Log in to the DUAE portal (with authentication)
  • Copy invoice/cargo manifest data manually
  • Look up tariff codes one by one
  • Wait for validation (it can take minutes if DUAE is slow)
  • If there is an error: Go back, correct it, resubmit

Problems: Typing errors, rejected declarations, time lost waiting on DUAE

Frequently Asked Questions - Cuba

A real API connection. We are not a web form that copies and pastes. aduanasHQ has direct API integration with the DUAE servers of the Aduana General de la República.

How it works:

  1. You enter data in aduanasHQ just once
  2. P4 validates against DUAE rules before submitting (preventing rejections)
  3. Click "Submit" → P4 transmits the digitally signed declaration to DUAE
  4. DUAE responds in 8-15 seconds with acceptance or rejection
  5. P4 shows the result immediately

Benefit: No copying/pasting, no logging in to the DUAE portal, no typing errors.

Yes, you can keep working. P4 automatically detects when DUAE is unavailable.

What happens:
