A trading company is a commercial business that buys products and sells it to customer. It handles products in a wide range of industries and is involved in all stages of the supply chain from development and purchasing of raw materials to manufacture, processing, distribution, and sale, providing services with high added-value. The function of a trading company is to identify constantly changing customer needs and to provide services that are a step ahead of the times.
There are two types of trading companies: general trading companies and specialized trading companies.
A general trading company operates in a wide range of fields and focuses more on business investment than on the basic trading business. In contrast, a specialized trading company operates a business in a specific field and focuses primarily on the trading business.

NST has a long history in each of the four business areas of steel, industrial supply & infrastructure, foodstuffs, and textiles, and has established a position in the top class of each industry. While a specialized trading company operates a specific business in a specific field, a multiple specialty trading company operates multiple specialty business areas as a single company. Because it operates businesses with professionalism and a high degree of specialization in each of the four business areas, NST is a multiple specialty trading company rather than specialized trading company.

A multiple specialty trading company constructs a solid position within the industry for specialized trading in multiple different business areas, and at times combines them organically to produce new value and business.
NST is a multiple specialty trading company that operates in the four core business areas of Steel, Industrial Supply & Infrastructure, Foodstuffs, and Textiles, and makes wide-reaching contributions to society by supporting basic human needs for food, shelter, and clothing.
The steel business and industrial supply & infrastructure business handle primarily industrial goods, while the foodstuffs business and textile business handle primarily consumer goods. The foodstuffs business provides food. The textiles business provides clothing. The steel business and industrial supply & infrastructure business provide shelter. In this way, NST operates four very different businesses as a single company, and utilizes the synergistic effects among them while expanding its business.
