I built a free customs calculation platform with 140 features (240 countries)

Why I built POTAL

Customs calculation infrastructure shouldn't cost $4,000/mo. I compiled every feature from 10 competitors — about 140 in total. The most feature-rich platform has ~30 features.

POTAL offers all 140 features for free. Forever.

For developers

  • REST API + SDKs (Node.js, Python)
  • AI Agent Integration (ChatGPT, Claude, Gemini via MCP)
  • Batch classification (bulk processing)
  • 240 countries, 51 languages
  • WCO GRI classification rules in code

Key features

HS Code classification (AI + image), Total Landed Cost, FTA origin determination, sanctions screening, denied party screening, export controls, de minimis thresholds, customs document generation, real-time currency conversion, dashboard + analytics.
