If the outer packaging of an international postal item displays any “dangerous goods labels” or “marks,” the item cannot be accepted for international mail (airmail or surface mail), even if the contents themselves are not classified as dangerous goods.
This is because it is not possible to determine from the exterior whether dangerous goods are included.
If such labels or marks are present on the outer packaging, please ensure that they are completely removed or obscured before sending the item.
For details, please refer to “Regarding the Removal of ‘Dangerous Goods Labels’ and ‘Marks’ from Postal Item Packaging.”
