Multi-UN Hazardous Gas Mixed Loading Export: How Xenon-Tritium Technology Solves the “High-Difficulty Compliance Transportation Challenge”

In the field of foreign trade export of hazardous chemicals gases, “multi-UN mixed loading” is widely recognized as a “high-barrier” segment—with large product category spans, stringent compliance requirements, and extremely low acceptance by shipping companies, many enterprises are deterred from such orders. However, in the special gas track, Chengdu Xenon-Tritium Technology Co., Ltd. (hereinafter referred to as “Xenon-Tritium Technology”) has become one of the few service providers capable of overcoming this challenge, relying on profound practical experience and mature foreign trade export capabilities. Meanwhile, it offers end-to-end supply solutions for high-purity gases and special gases to global customers.

Multi-UN Mixed Loading: The “Tough Nut” in Hazardous Goods Export—What Makes It So Difficult?

The core difficulties of multi-UN mixed loading lie in the “double superposition of risks and compliance”:

• High risk complexity: A single shipment involves different UN numbers (such as flammable gases, toxic liquids, and high-pressure gases). It is necessary to verify the compatibility between various substances (e.g., isolation between flammable gases and high-pressure containers, and pollution prevention between toxic liquids and high-purity gases). Any oversight may trigger chain hazards;
• Extremely heavy compliance costs: Each UN number requires separate preparation of MSDS (Material Safety Data Sheet), Dangerous Goods Packaging Certificate, classification identification report, and compliance with real-time updates of international regulations such as IMDG Code (International Maritime Dangerous Goods Code) and IATA DGR (Dangerous Goods Regulations). The error rate of documents is almost “zero tolerance”;
• High threshold for shipping company acceptance: The risk factor of multi-UN mixed loading is much higher than that of single-category goods. Most shipping companies directly reject such orders—even if they accept them, additional reviews of isolation plans, packaging tightness, and emergency response plans are required, along with increased insurance coverage, resulting in a significantly longer cycle than conventional dangerous goods orders.

Xenon-Tritium Technology: The “Compliance Transportation Expert” for Multi-UN Mixed Loading

The ability to tackle the “tough nut” of multi-UN mixed loading stems from Xenon-Tritium Technology’s practical accumulation in the special gas logistics field:

• Optimized mixed loading scheme design: It has successfully completed container mixed loading of 8 UN numbers, including Argon, compressed (UN1006), Silane (UN2203), and Toxic Flammable Liquid (N.O.S.) (UN1992). Through the design of “independent sealed units + physical compartments + secondary protective packaging”, safe isolation of different risk categories is achieved, accompanied by real-time leak monitoring devices;
• Accurate compliance document system: It issues separate compatibility analysis reports and customized MSDS for each UN number, and completes the full-process review by shipping companies, maritime authorities, and customs in advance, with a document accuracy rate of 100%;
• “Breakthrough capability” in shipping company cooperation: Relying on long-term cooperative resources, it covers global mainstream dangerous goods shipping companies such as HMM and Maersk. By adopting the model of “proactive risk undertaking + excess dangerous goods insurance”, it breaks the order access barrier for multi-UN mixed loading.

Mature Foreign Trade Export Capabilities: Supporting Global Gas Supply

In addition to the core capability of multi-UN mixed loading, Xenon-Tritium Technology’s foreign trade export system has achieved “end-to-end coverage”:

• Adaptation to international regulations: Proficient in multiple national dangerous goods transportation regulations such as IMDG Code, IATA DGR, and US DOT, it can flexibly adapt to various transportation methods including sea, air, and land transport;
• Global route and port resources: Routes cover core semiconductor and scientific research markets such as Europe, America, Japan, South Korea, and Southeast Asia. It has in-depth cooperation with customs and maritime authorities at major domestic dangerous goods ports such as Shanghai and Shenzhen, with customs clearance efficiency significantly higher than the industry average;
• Emergency order response: For urgent needs in the semiconductor and scientific research fields, it can respond quickly and complete the declaration and booking of multi-UN mixed loading orders with industry-leading timeliness.

Core Products: Global Supply of High-Purity and Special Gases

As the core carrier of foreign trade exports, Xenon-Tritium Technology’s gas products cover two core categories:

• High-purity gases: With a purity of 99.999% – 99.99999%, it includes industrial and scientific research-grade high-purity gases such as hydrogen, helium, argon, and nitrogen, meeting the high-precision requirements of scenarios such as semiconductor wafer manufacturing and laser fusion experiments;
• Special gases: Including rare gases (xenon, krypton, etc.), electronic special gases (nitrogen trifluoride, octafluorocyclobutane, etc.), and custom mixed gases (with a proportion error of <1%), which are widely used in high-end fields such as chip etching, medical anesthesia, and satellite propellants.

From the high-difficulty compliance transportation of multi-UN mixed loading to the global supply of high-purity and special gases, Xenon-Tritium Technology has become a trusted special gas service provider for foreign trade customers with its combined capabilities of “experience + compliance + resources”.
