A New Era of Safety: Understanding the Critical IMDG Code Update for Shipping Plant-Based Carbon (UN 1361)
What International Buyers Need to Know About SP978 and Its Impact on Your Supply Chain
As a leading international freight forwarder based in Shenzhen, China, we are at the forefront of global supply chain compliance. A significant regulatory shift is underway that directly impacts the shipment of common goods like charcoal, bamboo charcoal, coconut shell charcoal, and other plant or animal-based carbon products. The International Maritime Organization (IMO) has introduced a mandatory new provision — Special Provision 978 (SP978) to the IMDG Code (Amendment 42-24) for UN 1361, CARBON, animal or vegetable origin.
This is not a minor technical adjustment; it represents a fundamental evolution in how safety is managed for dangerous goods. For international buyers sourcing these products from China and globally, understanding SP978 is crucial for ensuring supply chain reliability, avoiding costly delays, and fulfilling your duty of care.
From a "Checklist" to a "Continuous Control" Mindset
Traditionally, shipping safety for such materials often relied on a Classification Test Report. This report, while essential, primarily confirms the laboratory properties of a submitted sample.
SP978 changes the game. It explicitly states that the standard UN N.4 test (for self-heating substances) can no longer be used to exempt these goods from the IMDG Code. The rule acknowledges the inherent risk of these materials and shifts the focus from proving a sample is "safe" to ensuring the entire shipment is prepared and handled safely.
Key Requirements Under SP978: What Has Changed?
The new regulation mandates a holistic, process-driven safety approach. Key obligations now extend back to the manufacturing and pre-shipment stages:
Mandatory Pre-Treatment: Bulk material must undergo a stabilization process before packaging. Shippers must choose one of two approved methods:
- Aging: Store the unpackaged material under cover but in the open air for at least 14 days after production; OR
- Inert Gas Treatment: After pyrolysis, treat the material with steam and cooling, and package it under an inert atmosphere (e.g., nitrogen). Subsequently, the packages must be stored under loose cover or in the open for at least 24 hours before transport.
Strict Packaging Condition: Material can only be packed on the day its temperature is 40°C or lower. This ensures a safe "starting state" for the logistics journey.
Engineered Stowage & Segregation: For cargo transport units (e.g., containers), specific engineering controls are required to prevent heat accumulation:
- A minimum 30 cm top space must be maintained inside the unit.
- Packages must not be stacked higher than 1.5 meters, OR if in larger blocks (max. 16 m³), a 15 cm gap must be left between blocks.
Implications for Global Procurement and Logistics
For international buyers, this means:
- Enhanced Due Diligence: Your sourcing and quality control must now consider the supplier's post-production treatment processes. A standard product specification sheet is no longer sufficient.
- Supply Chain Transparency: You and your logistics partners need clear documentation and possibly verification that the mandatory pre-treatment (14-day aging or inert gas process) has been correctly completed.
- Logistics Planning: The new stowage rules affect container loading plans and may influence pricing and space utilization. Working with a forwarder deeply knowledgeable in these new dangerous goods protocols is critical.
Conclusion: Partnering for a Compliant and Resilient Supply Chain
SP978 is a milestone born from industry lessons, moving dangerous goods safety from a point-in-time check to a full-process risk management system. It underscores that safety is a shared responsibility across the entire supply chain—from the production facility, to the packer, the forwarder, and the carrier.
At Goodhope Freight, we are proactively integrating these new requirements into our operational protocols and advisory services. We are prepared to guide our partners—both suppliers and buyers—through this transition, ensuring your shipments of UN 1361 materials are not only compliant but also secure from origin to destination.
