Last updated: August 2026 dataElemental oxygen traded under HTS 2804400000 serves critical roles across steelmaking, chemical synthesis, medical gas supply, and wastewater treatment. Japan leads US import supply, followed by Mexico and Italy, reflecting both proximity and specialty-gas manufacturing capacity. Because oxygen is classified as a compressed or liquefied gas, shipments must comply with DOT hazardous materials transport regulations, and medical-grade oxygen is additionally subject to FDA oversight as a drug product. Importers should confirm purity specifications and container certifications before entry, as grade distinctions affect both classification and end-use compliance.

Under heading 280440, all elemental oxygen — regardless of purity grade — falls under the single 10-digit line 2804400000. However, purity grade is commercially critical: medical-grade oxygen must meet FDA drug product standards, while industrial-grade oxygen is governed by DOT hazardous materials rules for compressed gases.
Importers generally need a Material Safety Data Sheet (SDS), DOT-compliant container certification, and, for medical-grade oxygen, FDA drug establishment registration and labeling compliance. Consult a licensed customs broker or the relevant agency to confirm current admissibility requirements.
