Notice Regarding Tariffs on U.S. Goods

We're aware that several countries have either increased or instituted tariffs on U.S. goods in recent months. This situation continues to evolve, and we recommend that you consult the appropriate resource for your nation's current tariff rates.

Canadian Customers:

We are specifically aware that as of August 1, 2025 Cananda has imposed a 25% tariff that applies to shipments of our Pet Intolerance Test and other goods. This tariff will be assessed in addition to any relevant taxes and processing fees typically charged by Canadian customs.

Q: Do I have to pay shipping to return my samples for the Pet Intolerance Test?
Yes, unfortunately we are not able to provide a prepaid mailer for tests sent outside of the U.S.


Q: Do I have to fill out the Pet Health Certificate when returning my Pet Intolerance Test samples?
No, the Pet Health Certificate is not required, but we strongly recommend including it with your pet’s samples. This document helps verify your pet’s health and can prevent delays if Customs inspects the shipment. While optional, it’s a helpful step to ensure smooth delivery! To complete the certificate, simply provide:

  • Your veterinarian’s name and clinic address
  • Your signature
  • The current date
