Guidance on Posting of Outbound Air Mail Items
Sending of air mail items (including Speedpost) that contain dangerous articles (including lithium battery, perfume and nail polish) is prohibited. Air mail items containing dangerous articles will be returned to the senders without any postage refund and the senders may be prosecuted for posting dangerous articles. Sender intending to post a returned mail item again shall ensure that it does not contain any dangerous articles and shall pay its full postage.
What are dangerous articles?
Common products containing lithium batteries
Pressurised containers (aerosols)
All air mail items must pass x-ray screening before dispatching overseas. It was observed that some articles which are not lithium batteries, items containing any built-in lithium batteries or flammable liquid, are difficult to be differentiated as their shapes or materials bear close resemblance to lithium batteries or flammable liquid during x-ray screening. Rejected items may be opened for further examination.

In order to reduce the chance of mail items not containing lithium batteries being rejected in the x-ray screening and required to be opened for further examination, senders should take note of the following points:
- Please check product packaging and description carefully for wordings in the same category of “lithium battery” (e.g. “lithium-ion battery”, “lithium”, “LI-ION” etc.) in order to prevent posting of any lithium battery or product containing lithium batteries by mistake.
- Please take out any removable lithium battery contained in the equipment and post it without the lithium battery.
- Equipment containing non-removable lithium battery must not be posted.
- Please do not attempt to post lithium battery wrapped in tin foil or by covering up the original lithium battery indication. It will not escape the screening.

For aviation security check and to facilitate inspection of airmail items that are suspected to contain dangerous articles, senders who send mail items containing non-lithium battery must also take note of the following points:
- Please extract the removable non-lithium battery inside any mail item as far as possible and, when these items have to be posted, the non-lithium battery removed should be placed separately for posting and clearly stated in the customs declaration form (See “Completion of Customs Declaration Form” below).
- Please accompany the product specification or manufacturer document to indicate the type of battery when indication is not given on the battery or equipment that contains it.
- Please do not send any battery or equipment that contains battery which cannot be identified.
- Completion of Customs Declaration Form: If a mail item contains any article shaped like a product with lithium batteries, please give a detailed description of the article(s) in the customs declaration form (e.g. “charger with alkaline battery 2 nos.”, “crystal decorated mobile phone case 3 nos.”).
- Proper Packaging: Packaging which can be easily resealed such as padded envelopes, carton boxes, etc. should be used to facilitate inspection by our staff and sealing of mail items after inspection.
Senders of Bulk Air Mail Service are required to pay attention to the above matters and mail items containing articles with close resemblance to lithium battery or flammable liquid should be posted in separate bags as far as possible. Since mail sent via Bulk Air Mail Service would be processed on bag level, Hongkong Post would not open any mail bags during mail processing. As such, the whole mail bag would be returned to the sender when it is rejected by x-ray screening. For enquiries, please call our 24-hour general enquiry hotline 2921 2222.
