The state government is working to ensure products such as seafood continues to reach international customers, including through trade offices in other countries and potential flights into Hong Kong and the United Arab Emirates.
Trade and Investment Minister David Ridgway met with seafood exporters in Port Lincoln on Friday to discuss freight measures and options going forward.
The commonwealth has also been providing support through the federal government's $110 million International Freight Assistance Mechanism (IFAM).
This has included securing a deal with Singapore Airlines to fly produce out of Adelaide to Singapore every Wednesday, including Eyre Peninsula seafood.
Mr Ridgway said the government had also ensured exporters had been kept up to date through staff in trade and investment offices in China, Japan, South Korea, United States, Malaysia and the UAE.
"We are optimistic we can continue to partner with the federal government to continue that service," he said.
Mr Ridgway said the government was talking to exporters about the possibility of more international flights, including to Hong Kong and the UAE. Trade concerns between Australia and China were raised following China's introduction of 80 per cent tariffs on the barley market.
Mr Ridgway said however that China remained an important market, but the government was also ensuring market diversity.
"We have not seen anything directly affecting fresh seafood and meat here at the moment," he said.
"China is an important market and will continue to be an important market."
Eyre Peninsula Seafoods executive director Andrew Puglisi said it was imperative to maintain export customers and income, which for the company was more than $1 million per year.
"All these things are stepping stones to keep our business successful going forward," he said.
"Export customers are a major part of our business and without them it's much harder."
