Ask Us How You Can Help Keep U.S. Ag Exports Competitive. We strongly recommend farmers verify that their seed varieties are approved for major export markets. We plan to selectively test loads delivered to our grain handling facilities. We reserve the right to reject crops with unapproved traits. If you have seed that is not approved for major export markets, we encourage you to check with your seed sales representative to see if your order can be exchanged for seeds that are approved for global use.
