集装箱铁水联运是多式联运的重要组织形式，是优化运输结构、促进交通物流降本提质增效的重要抓手。当前，铁路和水路运输在集装箱货物装载、安全检查要求及作业流程等方面仍存在差异，影响联运衔接效率。为贯彻落实《关于加快推进多式联运“一单制”“一箱制”发展的意见》有关要求，健全集装箱多式联运标准体系，交通运输部组织编制了推荐性国家标准《集装箱铁水联运装载和安全检查技术规范》（GB/T 48309—2026），将于2027年1月1日起正式实施。
该标准将规范铁路和水路运输衔接环节的装载加固和安全检查作业，提升集装箱铁水联运的作业协同性、安全性和运行效率，促进交通物流降本提质增效，为推动多式联运高质量发展提供有力支撑。
Container intermodal transportation is an important organizational form of multimodal transportation, which is an important lever to optimize transportation structure, promote transportation and logistics cost reduction, improve quality and efficiency. Currently, there are still differences between railway and waterway transportation in terms of container cargo loading, safety inspection requirements, and operational processes, which affect the efficiency of intermodal transportation. In order to implement the relevant requirements of the "Opinions on Accelerating the Development of 'One Order System' and 'One Container System' in Multimodal Transport" and improve the standard system of container multimodal transport, the Ministry of Transport has organized the compilation of the recommended national standard "Technical Specification for Loading and Safety Inspection of Container Iron and Steel Intermodal Transport" (GB/T 48309-2026), which will be officially implemented from January 1, 2027.
This standard will standardize the loading reinforcement and safety inspection operations in the connection between railway and waterway transportation, improve the operational synergy, safety, and operational efficiency of container intermodal transportation, promote cost reduction, quality improvement, and efficiency enhancement in transportation and logistics, and provide strong support for promoting high-quality development of multimodal transportation.
