SÃO PAULO, BRAZIL — Brazil’s zero-tariff wheat quota announced in March has gone into effect for 750,000 tonnes of wheat and is open to any country with no end-date, Reuters reported. 

Producers in the United States, Canada and Russia are expected to see most of the benefit from the quota, according to industry group Abitrigo.

Brazil is a net importer of wheat, producing around 5 million tonnes per year compared to consumption of about 12 million tonnes.

Most of that comes from Argentina, which has benefited from a zero-import tax for years, the news agency said. The United States has been a regular source of wheat, but on a much smaller scale.
