Port Inspections

CBP Agriculture Specialists, please refer to manuals for general inspection guidelines. When performing inspections, look for yellowing and other pest evidence, and verify the products and packaging are free of red palm mite and any other pests. Also examine souvenirs of palm and leaf handicrafts carried by travelers from the Caribbean.
