‘Product of’ and ‘Grown in’

'Product of' and 'Grown in' means that each significant ingredient or part of the product originated in the country claimed and almost all of the production processes occurred in that country.

‘Product of’ is often used for processed food and ‘Grown in’ is mostly used for fresh food.

For example

• If ‘Product of Australia’ appears on a packet of smoked salmon, this means the salmon was both caught and smoked in Australia.
• If ‘Grown in Australia’ appears on an apple, it was grown in Australia.
