The NFU is meeting with senior US officials this week on resuming beef and lamb exports to the country.
President Meurig Raymond is leading a UK delegation to Washington. It will meet with the EU ambassador to the US and other US representatives to discuss exports as well as EU-US trade talks and food safety standards.
Mr Raymond said: "UK beef and lamb exports have been banned since the 1990s. Efforts are underway to resume exports, but progress, especially on lamb has been slow. I will meet senior officials to press for progress and promote the quality of our excellent products.
"At the same time, this visit is a chance for us to highlight the world-class welfare standards that set us apart from the rest of the world and that must be recognised in future trade deals."
He said the visit would also give UK industry chiefs the chance the learn more about US approaches to regulation and how it differs from regulation in the EU.
"I am particularly keen to find out more about the US’s approach to adopting and taking advantage of emerging biotechnology and the country’s differing approach to plant protection products," Mr Raymond said.
According to the Food and Drink Federation the US was worth £563 million to UK food and drink in 2014, with trade increasing £49.6m.
