Calculating the estimated billing weight and actual billing weight of the parcel is a function of iviBuy to protect the interests of both users and the platform. The difference in freight will be returned in time, which is benefited to users and let users cost no extra money.

What is estimated billing weight?

After the goods are put into storage, there will be a weight with the original packaging of the goods. When submitting the parcel, the system will estimate the packaging weight according to the weight of the goods in storage and calculate the total weight. If you request to remove the packaging when submitting the parcel, the weight after packaging will be inconsistent. That is the total weight when submitting the parcel is the estimated billing weight.

What is the actual billing weight?

After the parcel you submitted is packed, the warehouse will weigh and measure it. If the parcel arrives at the logistics provider's warehouse, the logistics provider does not adjust the billing weight of the parcel, that the actual billing weight is based on the warehouse weighing and measuring.
If the logistics provider adjusts the billing weight of the parcel, that the actual billing weight is based on the logistics provider's measurements. The actual billing weight can be inquired by clicking "details" on the parcel page 3 days after the it being sent out.

Tips:
International freight is billed according to the actual weight and volume weight of the parcel. When choosing the logistics route that will calculate the volume weight, if the volume weight of the parcel is greater than the actual weight, it will be charged on the volume weight, that the actual billing weight of the parcel is the volume weight.
If the actual billing weight of the parcel is greater than the estimated billing weight, the system will notify the user to complete the pending payment. If the estimated billing weight of the parcel is greater than the actual billing weight and exceeds the continued weight, the system will automatically refund the difference to your iviBuy account balance within 72 hours after the parcele is shipped.
