Cargo is transported by air, ship, automobile or rail. Freight shipments are usually boxes or containers of products, but person-to-person freight is also common. Sampling and scanning are used to ensure the correct shipment. Domestic and international shipments are common, with ocean freight being the preferred method for large quantities.
Cargo is generally defined as freight transported by air, ship or automobile methods. Sometimes freight is displaced by rail, but this method is generally less common. In most cases, shipments consist of boxes or containers filled with material or products being transported from one company to another, however, combined together, person-to-person freight accounts account for a substantial portion of worldwide shipping. Most freight shipments are domestic, but due to the globalization within business markets, international freight shipments are also common. For safety and product handling reasons, containers are often scanned and sampled.
One of the primary considerations for shipping large quantities of cargo from one company to another is to have a system in place to make sure that the cargo shipped is exactly what was ordered. This is especially true with international shipments, where transportation charges can be expensive and the time taken to return the unsatisfactory product is often excessive. Most companies use various methods of sampling goods to avoid these problems.
Freight sampling typically involves checking shipping containers or boxes at various points during the shipment. These checks are usually performed on random containers and the results are reported to both the shipper and the receiving party. Larger companies may have their own staff who take samples, but in many cases the work is outsourced to private contractors who specialize in the field.
Cargo scanning is usually performed by local authorities to check the contents of packages or containers. The scans are normally performed by officials trained in the use of scanning devices using X-ray and gamma-ray technology. More often than not, they are able to verify the contents of the cargo without having to actually open the packages. If the imaging results do not match the information on file for a particular shipment, the container is typically opened and carefully examined.
Most goods are shipped domestically, often using a combination of air and automobile transportation for shipping and delivery. Some businesses that require periodic large cargo shipments often use trucking companies for pickup and delivery services. Businesses that ship a large amount of products on a regular basis often have their own fleets of trucks that handle their shipping needs.
In most cases, large international shipments are shipped via ocean freight. This is because the size and weight restrictions placed on air travel make it an impractical and expensive method for companies shipping large quantities of goods. Some international companies use their own ships to transport goods, although it is much more common to contract the services of shipping lines.
