The joint ventures and solely invested companies by Praxair (China) Investment Co have raised the prices of bulk oxygen, bulk nitrogen, bulk argon, and carbon dioxide by 10 per cent in northern, eastern, and southern China markets since the beginning of April this year.

Praxair explained that the price increases mainly resulted from rising fuel and energy costs in producing oxygen, nitrogen, argon and carbon dioxide. Praxair has taken this action as an effort to ensure customer reliability and service in the tight supply market of these products.

Praxair is also advising its distributors of additional charges for exceeding contract volumes. In addition, the company will be reviewing the pricing structure for direct customers where the existing contracts permit.
