If the courier items are overweight, you can negotiate with the courier company and ask them to pay the overweight fee according to the regulations of the courier company. Usually, the calculation method of the overweight fee of the courier company will be different according to different regions, different courier companies and different courier services, so the specific overweight fee to be paid may be different.
In addition, it is recommended to know the relevant regulations and charging standards of the courier company before sending the courier, so as to avoid paying extra fees due to unreasonable delivery. If you have any questions or unclear places, you can consult the customer service of the courier company to get more accurate answers and guidance.
