Will you be subject to customs duties when you bring back a batch of photographic equipment from abroad?

No, last time I went back to China, I brought a batch of old computers collected on EBAY. It doesn't matter if you don't exaggerate. Customs may not check that you brought five old machines to check for new portable lenses last time. Tragedy is best not to look too much. You can take your head off, and you'd better bring a CCD. It's also fragile, just don't exceed 20KG.

The customs also checked the exit regulations that only one cigarette can be brought. How many people were checked for bringing two cigarettes? Not that I know of.
