How to choose an envelope so as not to overpay for shipping?
The same document may cost more to ship if placed in a larger envelope. Therefore, it is worth choosing the packaging according to the contents, and then measuring and weighing the finished shipment.
A4 document submitted to DL
A document folded into thirds will usually fit in a DL envelope and may qualify for S format.
A4 document without folding
A C4 envelope allows you to send an A4 sheet of paper without bending it, but usually means M format.
When shipping documents, samples or other approved items may be considered envelopes available at AWIH, including protective and extended versions. It is always worth checking whether the type of shipment allows you to send a given content.
