An importer desiring to import pesticides or devices into the United States must submit to EPA a Notice of Arrival of Pesticides and Devices (Environmental Protection Agency Form 3540-1 or Notice of Arrival ), prior to the arrival of the shipment in the United States. Through the Notice of Arrival, the importer reports vital information to EPA such as the major active ingredients, quantity, port of entry, and points of contact. This information allows EPA to make informed decisions, before pesticides arrive in the United States, as to whether such importation will pose unreasonable adverse effects on public health and the environment. The Notice of Arrival also provides contact information in the event of an emergency related to the movement of potentially toxic materials.
