Canada Customs & Border Protection Policy

Authority: CATSA

Requires declaration for foods, plants, and select medicines. When flying internationally, you must comply not only with U.S. TSA regulations but also with the aviation security rules of your destination country and any transit hubs. For coin cell batteries, policies can vary significantly in regions like the European Union (governed by EASA) or the United Kingdom (CAA). Some countries impose stricter volume limits on liquids, absolute bans on specific electronics, or rigorous customs declarations for items in the Electronics category. Always check the official customs and aviation authority website of your arrival country before packing this item.

Airport Security & Customs Screening Procedure

During security screening for coin cell batteries, any device larger than a standard smartphone (such as laptops, tablets, or large camera equipment) must be removed from your carry-on luggage and placed in a dedicated screening bin with nothing underneath or on top. Power banks, spare lithium-ion batteries, and rechargeable devices must remain in your carry-on luggage and are strictly forbidden in checked baggage due to FAA cargo fire safety protocols. Turn off high-capacity battery units to prevent accidental activation during flight.

Step 3

Protect exposed terminals on spare batteries by covering contacts with tape or storing them in individual plastic pouches.

Step 4

Be prepared to remove large electronics (larger than a mobile phone) from your bag to lay them flat in a TSA screening tray.

Step 5

Store delicate screens and components inside a padded sleeve to protect them from impact during boarding and overhead-bin loading.
