1. Classification — Class I does not settle the route
The scope of what counts as a veterinary medical device is set by notice. You confirm whether the product is designated before anything else, because that is what decides whether it is regulated at all.
Class comes next, and this is where human-use instinct misleads. On the human-use side the class fixes the route. On the veterinary side Classes II–IV are product approvals, while Class I qualifies for notification only when it is substantially equivalent to a product already approved or notified. A Class I device with no precedent goes through approval.
A schedule and budget built on “Class I, so notification” collapses if the route turns out to be approval. Checking the class is not enough — you have to check precedent.
