Shipping to the United States
We're happy to offer free shipping on all Plaque Guard orders to the United States. As a Canadian product, Plaque Guard qualifies for duty-free entry under the Canada-United States-Mexico Agreement (CUSMA), and the vast majority of our U.S. customers receive their orders without any additional charges.
That said, we want to be fully transparent: U.S. trade and customs regulations are subject to change, and under the current administration, policies have been evolving rapidly. While we ship in full compliance with CUSMA, U.S. Customs and Border Protection (CBP) retains the authority to assess fees at their discretion.
Please be aware that you may be charged for any of the following at the time of import:
- Customs brokerage fees
- Import processing fees
- Duties or tariffs
These charges, if applied, are determined solely by U.S. Customs and Border Protection and are outside of our control. Koa Healthcare is not responsible for any fees assessed by CBP upon entry of your shipment into the United States.
We recommend that U.S. customers stay informed about current import regulations. You can find up-to-date information directly from U.S. Customs and Border Protection here: U.S. Customs & Border Protection – USMCA
If you have questions before placing an order, we're always happy to help
