I agree with that assessment 100%. A lot of NTBs are things that people often don't see or hear about. It could be a departure from international standards; it could be increased processing times; it could be stepped-up inspections where they're not warranted—all these things. A lot of them are procedural based, or other factors that are not visible to most people most of the time.
To Dave's point, while there are some that are tied to intellectual property, I would say that the vast majority are not.
