Prior Notice deadline calculator
Choose how the food arrives and when it reaches the U.S. port. The calculator shows the latest time FDA must have confirmed your Prior Notice (2 hours before arrival by road, 4 by rail or air, 8 by water) and the earliest you can file in PNSI (15 days before), in port time and your time.
General information under 21 CFR 1.279; not legal or customs advice. Build in a margin: FDA must have confirmed the filing by the deadline.
