The dataset on export restrictions is an original dataset developed by the OECD for AMIS. It is constructed by gathering information from official legal documents, government websites and other reliable sources.

The data on import tariffs, tariff quotas and producer and consumer support were extracted from existing WTO or OECD databases. Links to these databases and their detailed methodology documents can be found below:

• Tariff Analysis Online facility (WTO). This facility allows you to access the WTO's Integrated Data Base (IDB) and Consolidated Tariff Schedules (CTS) database on-line
• Producer and Consumer Support Estimates database (OECD). Policy data and indicators on government support to agriculture.
