These updates align with revised hazardous cargo classification guidelines issued by PSA Group, particularly concerning lithium-based batteries and battery-powered equipment. The reclassifications impact port-side operational requirements—including cargo handling procedures, stowage segregation, emergency response protocols, and documentation standards.
Reclassification of battery-related dangerous goods
Certain battery-related UN numbers will be reclassified from PSA Group 3 to PSA Group 2, reflecting an elevated risk profile under PSA’s updated safety framework.
The affected UN numbers are:
UN3090, UN3091, UN3171, UN3480, UN3481, UN3536, UN3551, UN3552, UN3556, UN3557, and UN3558.
These revised classifications—and the corresponding DG handling surcharges—apply exclusively to containers transshipped through Singapore.
Mandatory monitoring for high-risk battery shipments
In addition, PSA Group will implement mandatory real-time monitoring services for selected battery-related dangerous goods during port dwell periods. This measure responds to a documented increase in thermal incidents and operational exceptions involving lithium battery cargo, as cited in PSA’s latest safety advisory. Monitoring will be required where extended container dwell times at terminal facilities may heighten thermal runaway risks.
Customer compliance requirements
ONE urges shippers to submit complete, accurate, and timely dangerous goods declarations in accordance with the International Maritime Dangerous Goods (IMDG) Code and local regulatory requirements. Non-compliance—including incomplete declarations, misclassification, or failure to arrange mandatory monitoring—may result in cargo rejection, service delays, financial penalties, or operational suspension.
Effective date and applicability
The updated DG handling charges and monitoring requirements take effect on 3 August 2026 for all non-FMC-regulated trades, FMC-regulated trades, and Canada-bound shipments. Additional local surcharges or contingency fees may apply, subject to prevailing port authority regulations and contractual terms.
