2. How will vPost decide which packages to repack?
We will repack your package if the difference between the actual weight and volumetric weight is 2kg or more.
Will you repack every package that has more than 2kg difference between the actual weight and volumetric weight?

4.Here are some scenarios in which we will not repack:
a. when the package contains leather products, e.g. handbags, purses, coats, etc.
b. when the package contains products with flammable or alcoholic contents, e.g. perfume samples, perfumes, body mist samples, etc. (These products will be disposed off if discovered during the repacking process. Click here to view the list of prohibited items.)
c. when the package is marked 'FRAGILE'.
d. when the package is obviously a gift, i.e. packed in a gift box, secured with ribbon and gift card, etc.

There are also packages which are specially packed to ensure breakable items are cushioned. As such packages would potentially be bulky, the difference between the actual weight and volumetric weight may be higher. We will take into account such instances and repack only when the safety of the package will not be compromised.

The decision to repack a package will be made at the discretion of vPost.
