Are PVC threads NPT?

Could you please clarify for me if PVC threads are indeed NPT (National Pipe Thread Tapered) compatible? I understand that NPT is a standardized threading system commonly used in piping and plumbing, but I'm not sure if PVC threads specifically adhere to this standard. Is there a distinction between PVC threads and NPT threads, or are they interchangeable in certain applications? It would be great if you could provide some insight into this matter.
