UK Online Trade Tariff

What it does

The UK Online Trade Tariff: a Rails backend that imports updates and serves commodity codes, duties, measures, quotas, certificates and rules of origin, the public website and duty calculator, an admin tool and a Python tool for Electronic Tariff files. Runs as a UK or Northern Ireland service on PostgreSQL, OpenSearch and Redis. MIT with Crown copyright; the seed data is not a complete tariff.
