What is NOT a characteristic of an International Health Certificate (IHC)?

The characteristic that is not true about an International Health Certificate (IHC) is its validity period. Typically, an IHC is valid for a certain duration following issuance, but the standard validity period tends to vary depending on specific regulations of the importing country, not a fixed 45 days.

International Health Certificates are vital documents for the export of animals, ensuring that they meet health and safety standards as required by the destination country. They must be endorsed after completion by an accredited veterinarian or a relevant authority, which ensures that all necessary health checks and vaccinations have been properly documented. Additionally, these certificates usually include detailed regulations that outline the health requirements and the conditions under which the animals can be exported.

Therefore, asserting that the IHC is valid for a uniform period of 45 days does not accurately reflect the nuances of international health regulations, making this the correct answer.
