The SA Post Office has seen a rise in the number of international airmail parcels that cannot be dispatched as they contain items that are classified as unsafe for air cargo. Regulations regarding the transport of air cargo have been tightened. No substance that could combust, explode or leak out in transit may be posted. Items that are no longer allowed as airmail include lithium batteries, liquids, creams and lotions. All outgoing mailbags are scanned for items not allowed as air cargo, and all bags contained banned items are returned after being screened. Customers are, therefore, requested not to include such items in parcels they send abroad. Other substances that may not be posted include any flammable or explosive items. Most countries do not allow the import of poisons, drugs, or medication without an import permit. Further, items that may not be posted are uninsured jewellery or precious stones or precious metals, or any film or publication which falls in category XX or X18 of the Films and Publications Act 65 of 1996 as amended.Make sure your parcel arrives safely Parcels must be packaged securely, as they are transported in bulk. If your mail item does not fill the container, fill it with packaging material like shredded paper or polystyrene to act as a shock absorber. When ordering an item from abroad, ask the sender to put your cellphone number on the parcel. That way you can be notified by SMS when the parcel is ready for collection.
