Nitrogen

Traded in both gaseous and liquid form, nitrogen is a foundational industrial gas serving food packaging (modified-atmosphere preservation), electronics manufacturing, and chemical synthesis as an inert purge medium. Taiwan leads US import supply under tariff line 2804300000, followed by Canada and Japan — a supplier profile that reflects the density of semiconductor and electronics facilities in East Asia that export specialty nitrogen. Bulk liquid nitrogen shipments require cryogenic container compliance, and classification questions occasionally arise when nitrogen is co-packaged with other gases.
