Corporate Philosophy

Gas Technologies for The Future

Through mini gas cylinders and related equipment, we contribute not only to the development of the industry but also to the achievement of safety and security, health, and the comfort of society.
As a member of society who engages in the gas industry, NTG cares about the environment. The carbon dioxide in NTG’s cylinders is not produced by burning chemical fuels. We purchase CO2 which is generated as a by-product in the manufacturing process of steel and petrochemical products, and reused for our products. NTG strives to protect the global environment and to enrich society while broadening and strengthening its technologies.

Code Of Conduct

Conflict Minerals Policy

NTG is aware of our legal responsibilities regarding Conflict Minerals.
We do not directly source or process the 3TG (Tin, Tantalum, Tungsten, or Gold). Our mini gas cylinders are made from steel and none of the 3TG minerals are contained within it. Even though a very small amount of Tin (Sn) is contained in our brass-body regulators (as an Fe-Sn alloy component), we have confirmed with our suppliers that the material is not a Conflict Mineral from the Democratic Republic of Congo or its surrounding countries. Therefore, we hereby certify that all NTG products are Conflict Mineral Free.

Labor Policy

NTG respects all applicable laws regarding labor rights. We do not use child labor in any of our facilities or subsidiaries. We expect that all the companies we do business with also agree with this policy statement.
