Material transportation refers to a service that transports raw materials, semi-finished products or finished products from 

the place of production to the destination, which covers the business of all kinds of logistics and transportation companies. 

Material transportation industry can be divided into the following main categories:

1. Road transport industry: including truck transport and logistics distribution. Trucking transport is usually provided by

 freight companies or freight agents for short or long-haul freight transport. Logistics distribution refers to the delivery of

 materials from distribution centers or sorting centers to end-users or retailers.

2. Railway transportation industry: Railway companies provide long-distance freight transportation services, which are

 suitable for transporting large quantities of goods. Rail transport is generally more cost-effective than road transport, 

especially in mainland transport and international trade.

3. Air transport industry: Air cargo is mainly provided through airlines, which is suitable for transnational cargo transport 

and time-sensitive goods. Air transport is usually fast but more expensive.

4. Water transportation industry: including sea transportation and inland river transportation. Sea shipping is a common 

way of transporting large volumes of cargo, which can be done through container ships, bulk carriers, and oil tankers.

 Inland river transport is suitable for the transport of goods along the river area.

5. Pipeline transportation industry: mainly used for conveying liquid or gas materials, such as oil, natural gas and chemicals. 

Pipeline transportation is often managed and operated by energy companies or utilities.

6. Multimodal transport industry: Multimodal transport refers to the combination of different transport modes in order to

 transport materials more efficiently. For example, goods can be transported from the factory to the railway station, then

 transported to the destination and then delivered by truck.

The above is the main classification of the material transportation industry. With the development of technology and

 globalization, the material transportation industry continues to innovate and change, and strive to improve the transportation

 efficiency and reduce costs.
