I think we will often encounter customers such questions, 

whythe goods to your warehouse size will become larger?DHL

Why the cargo box will be more 1-2cm, obviously

 my goods are new boxes,....

Before answering this question,

 let's take a look at how international courier companies measure the size of goods.

Here take DHL as an example,

 as an important part of the transaction process,

 weighing and billing for the parcel is essential,

 DHL operation guide also has a special introduction.

What is Volumetric Weight?

Volumetric weight is

 a method used in the transportation industry

 to calculate the weight of lightweight shipments.

Volumetric weight is the

 weight of a shipment obtained by taking the volume of the shipment and

 using a conversion formula.

Volume weight formula = length cm × width cm × height cm / 5000

 international freight is based on the weight of goods and volume weight billing,

 when the volume weight of the parcel is greater than the actual weight will be billed in accordance with the volume weight.

Different courier companies total billing weight calculation method is a little different

 to UPS the most special.

The operation of the irregular goods:

 the actual operation of the volume of weight has three kinds of measurement:

 ① standard parcel measurement:

 parcels for the standard carton size,

 according to the carton length, width and height of the volume of weight calculation.

Example: such as DHL channels, parcel length 15, width 30, height 20,

 then the volume weight = (15 × 30 × 20) / 5000 = 1.8KG,

 and the actual weight of 1.2KG,

 the parcel according to the volume weight of 1.8KG calculation of freight charges, the final

 billing weight of 2KG.

 ② curved parcel measurement:

 such as parcels due to the extrusion of goods leading to the case of the plane of the case of the expansion deformation of the bulge,

 then the parcel is calculated according to the longest side.

Example: such as DHL channel, the actual length of the carton 15, width 30, height 20;

 due to the extrusion of goods, after sealing the box length 18, width 33, height 22,

 then the volume of weight = (18 × 33 × 22)/5000 = 2.7KG,

 while the actual weight of 2KG,

 the parcel according to the volume of weight 2.7KG calculation of freight charges,

 the final billing of the weight of 3KG.

 ③ Irregular parcel measurement:

 because of the actual size of the goods need to be packaged into irregular packages

, then the

 package is calculated according to the

 longest side of the package. 

③ Irregular parcel

 measurement: Because of the actual size of the goods need to be packed into irregular parcels,

 the parcel is calculated according to the longest side of the volume weight.

Example: If DHL channel,

 the longest length of irregular parcel is 15, the longest width is 40, the longest height

 is 25

, then the volume weight = (15 × 40 × 25) / 5000 = 3KG,

 and the actual weight is 2KG,

 the parcel is calculated according to the volume weight of 3KG freight.

DHL actually operates

 the laser measurement in the middle carefully:

 the parcel detection is a 3D lens + algorithm solution, which

 automatically takes the length of the side at the bulge and derives the volume weight.

It is capable of realizing millimeter-level recognition accuracy.

Measuring machine uses

 V-SLAM algorithm in the field of industrial robotics

 for real-time positioning of the lens to

 improve the stability of the product to the environment, and

 can be used in the warehouse and other disturbing environments;

 Combined with the barcode recognition technology and weighing sensors,

 the barcode can be quickly identified and associated with the volume weight data.

It is able to recognize the barcode and correlate it with the volume and weight data. The volume information of the goods can be accurate to 0.5mm error, with

 high precision, and it can realize the volume weighing under static and dynamic conditions at the same time.

Whether it is sea or air transportation,

 measurement of size, whether it is carton packaging or irregular packaging

 will be the longest or the most convex out of the point to measure the size of the

 actual shipment with you, the size of some of the larger,

 because the transportation and loading and unloading of the handling may produce deformation of the box,

 but the gap will not be too big, basically,

 1-2cm belongs to the normal category.

Another regulatory requirements,

 most freight forwarding companies,

 there will be a security check machine,

 similar to the subway through the security check,

 to detect liquid powder batteries and so on.

First of all, from the professional ethics,

 the business of the regular freight forwarding company,

 in fact, the whole process can not see the goods,

 the size of the shipping system data are subject to

 business is not a hammer sale,

 lose a customer than to develop a customer is too easy.

To cooperate with customers,

 honesty and trustworthiness is the most basic professional ethics.
