Common Issues found in Mail Security Inspection

All mail items must pass the security check before despatching to other destinations. It is observed that some articles which are not dangerous, such as ordinary battery, circuit board, shaped hard disc, etc, are difficult to be differentiated from dangerous articles as their shapes or materials bear close resemblance to dangerous articles during x-ray screening. Hongkong Post may arrange these items to be opened for further examination.

Lithium battery is nowadays the most common dangerous article found in mail item.

Posting Liquid

The other most common article that could hardly be ascertained as non-dangerous is liquid. We shall return all mail items containing unidentified liquid. Senders are hence recommended not to post any item that contains liquid. If it has to be posted, the liquid must be contained in its original packing with composition and ingredients clearly indicated to facilitate security check. In addition, supporting document such as Material Safety Data Sheet (MSDS) should also be provided.

Proper Packaging

Packaging with sufficient protection which can be easily resealed should be used to facilitate inspection by our staff and resealing of mail items after inspection. Hongkong Post is not liable for any damage of article in the mail processing as well as the examination process.
