Travelers entering the United States must declare all agricultural or wildlife products.
Travelers entering the United States must declare all agricultural or wildlife products to U.S. Customs and Border Protection officials. You must also tell them if you visited a farm or were in contact with animals before traveling to the United States.
U.S. agricultural inspectors will examine your items to be sure they meet entry requirements and do not harbor harmful foreign pests or diseases. U.S. inspectors have the authority to make a final determination about whether your products can enter the country. We recommend that you keep receipts and original packaging of agricultural products as proof of their country of origin.
As long as you declare all of the agricultural products you are bringing with you, you will not face any penalties—even if an inspector determines that they cannot enter the country.
