Is the micro-camera a precision instrument? Overseas purchasing, is the camera a commodity that cannot be imported?

Micro-scale is a photographic equipment, not an instrument, nor a precision instrument. Purchasing is definitely no problem, but you have to pay customs duties. The main problem is that the purchasing platform must be a regular e-commerce platform to rest assured. WeChat merchants and unfamiliar shopping websites should be careful. In addition, there will be problems with after-sales service. Many manufacturers' products are guaranteed regionally, but there is no global guarantee. In case something goes wrong, it will be troublesome to repair it. Also, buying a camera is not necessarily cheaper than domestic ones.
