Prohibited Items Entering The United States
When you enter the United States, US Customs and Border Protection (CBP) enforces federal law at the border. Some goods that are easy to buy in Canada are still restricted, taxed, or banned in the US. This page summarizes common pitfalls; always confirm with CBP before you pack.
Fruits, Meats, And Animal Products
Many fresh items and meat products are prohibited or require advance permits because of animal-disease controls. Jerky, sandwiches with meat, hunting trophies, and pet food can all trigger agriculture secondary inspections.

Medications
Travellers may bring a personal supply of medication in many cases, but narcotics, injections, and large quantities can require extra documentation. Keep pills in original pharmacy packaging when possible and carry a copy of the prescription for controlled drugs.

Weapons, Ammunition, And Defensive Sprays
Federal and state rules interact at the border. Items such as Mace or pepper spray intended for use on humans, certain knives, firearm parts, and ammunition often require paperwork or are simply inadmissible in personal baggage. Declare firearms and ammunition through the proper channels—never hide them.

Currency
If you carry more than US $10,000 (or foreign equivalent) in cash or monetary instruments, you must report it to CBP using FinCEN Form 105. Non-reporting can lead to seizure and penalties.

Counterfeit Goods And Cultural Items
Fake designer goods, pirated media, and some cultural artifacts or wildlife products (even when sold legally elsewhere) can be seized. If you are unsure, leave it at home or obtain explicit import permission before travel.
