Maritime Dangerous Goods — Regulatory Watch
CINS’s August 2026 recommendation paper argues that Special Provision 188 needs a limit at the container level, not just the package level, and backs the case with its own incident data and a real-world fire.
The Cargo Incident Notification System (CINS) has published a recommendation paper calling for tighter control of Special Provision 188 (SP188) of the IMDG Code, the clause that lets qualifying lithium-ion cells and batteries move as non-dangerous cargo. SP188 was written with a single package in mind — a phone battery, a laptop pack. CINS argues it was never adjusted for what happens once hundreds of those packages end up sharing one container.
CINS calls the resulting condition, in its own words, “out of sight, out of control.” Rather than scrapping SP188, the paper recommends tying the exemption to whether the transport chain can actually see and track the batteries moving through it.
What CINS Recommends
- Mandatory declaration for all lithium-ion batteries, including shipments currently exempt under SP188;
- A new CTU (Cargo Transport Unit)-level quantity limit, to stop unlimited accumulation of SP188-eligible batteries inside one container;
- A specific number for that limit — CINS recommends capping SP188 relief at 20 kg gross battery mass per CTU, citing the existing SP963 nickel-metal hydride threshold (100 kg per CTU) as a workable precedent; anything above the cap would need full IMDG declaration and compliance under Chapter 5.4;
- Conditional relief, with the SP188 exemption preserved only where the transport chain keeps visibility, traceability and control, rather than as a default “non-DG” acceptance route;
- Evidence drawn from CINS’s own incident file, updated as of 1 July 2026, covering misdeclaration, packaging failures, battery quality issues and stowage/emergency-response challenges.
How the Numbers Interact
The 30 kg and 20 kg figures aren’t the same limit, and it’s easy to conflate them. SP188’s existing 30 kg cap applies per package. CINS’s proposed 20 kg cap would apply per container, added up across every package inside it. A single 25 kg package sits comfortably under the package limit on its own, but already exceeds CINS’s recommended CTU limit by itself — one compliant package could still trigger full Chapter 5.4 declaration for the entire container. Going the other way, five ordinary 4 kg consumer-electronics packages reach that same 20 kg threshold through plain accumulation, with no single package anywhere near its own limit.
What This Covers — and What It Doesn’t
Scope: Lithium-Ion Only
CINS limits its recommendations to lithium-ion cells and batteries — UN 3480 and UN 3481 — whether shipped alone or packed with equipment. Lithium metal batteries (UN 3090 and UN 3091) are not covered by this paper. SP188 treats that chemistry under its own separate thresholds, and CINS makes no proposal on it here. The two are easy to mix up in day-to-day compliance work, so it’s worth keeping them separate from the outset.
The Evidence Behind the Recommendation
| Root cause | What CINS observed | What it implies |
|---|---|---|
| Misdeclaration | Equipment containing lithium-ion batteries booked as ordinary consumer goods; declared specifications not matching the cells found on inspection | Carrier screening at acceptance isn’t catching everything; the gap starts at the shipper’s declaration |
| Battery quality | Defective cells, poor manufacturing quality and high states of charge, concentrated in low-cost shipments with weak packaging | Individual battery size alone doesn’t capture the risk — cell quality and accumulation matter just as much |
| Packaging non-compliance | Missing inner packaging and terminal protection, batteries exceeding SP188 size limits, inconsistent test reports and markings | SP188 relief should depend on verified compliance, not assumed compliance |
| Safety-framework gaps | Reduced visibility undermining stowage, segregation and emergency planning as volumes and product types multiply | Maritime operations need a workable control point at the container level |
One Container, Dozens of “Invisible” Packages
CINS’s incident file includes cases where large numbers of individually SP188-compliant battery packages — each correctly tested, packaged and marked — were consolidated inside a single container. The single red square marks one package where a cell has failed. Nothing in SP188 requires the container itself to carry a mark, a placard or a transport document, so the accumulated load carries no warning until something goes wrong.
Operational Consequences CINS Has Recorded
CINS’s incident file records fires and explosions in ships, terminals and depot yards; large concentrations of small SP188-eligible batteries building up inside single containers; fire spreading beyond the originating box into surrounding cargo, with stability concerns where holds are flooded during firefighting; extended shore response requiring multiple containers to be discharged and later handled as waste; and hydro-pen or punch-nozzle firefighting systems losing effectiveness where stowage position restricts access.
A Real-World Case: X-Press Godavari (2020)
Transport Malta’s investigation into a 2020 fire aboard the X-Press Godavari shows what this accumulation risk looks like in practice.
| Vessel | X-Press Godavari (IMO 9353735), Malta-flagged, Singapore-managed |
| Date | 28 September 2020 |
| Location | Sandheads Anchorage, off Kolkata, India |
| Cargo | 500 cartons lithium-ion batteries (7,450 kg) plus rechargeable torches and spares (9,311 kg), China to Kolkata |
| SP188 status | Every package correctly marked and certified; no container-level marking, placard or declaration required or provided |
| Crew awareness | ∼90 minutes fighting an unidentified fire before the charterer confirmed cargo contents |
| Firefighting | No water mist lance (not required for a ship built in 2008), insufficient CO2/dry-chemical for a 40-ft box; boundary cooling only |
| Duration | Fire fought for 37+ hours, from first smoke to shore firefighters still working the box |
| Outcome | No injuries; container craned off at Kolkata; burning cargo spilled onto the container below during unloading |
| Aftermath | Operator (Sea Consortium) briefed the master, tightened charterer declaration checks, issued a fleet circular |

At a Glance: SP188 Today vs. CINS’s Proposal
| Aspect | SP188 Today | CINS Recommends |
|---|---|---|
| Per-package limit | 30 kg gross mass (except when installed in/packed with equipment) | Unchanged — CINS targets the CTU, not the package |
| Per-CTU limit | None | 20 kg gross battery mass per CTU |
| Declaration below threshold | Not required | Mandatory declaration for all lithium-ion shipments, regardless of threshold |
| Above the threshold | N/A — no CTU threshold exists | Full IMDG Code declaration and compliance under Chapter 5.4 |
| Scope | Multiple battery chemistries, per SP188 conditions | Lithium-ion only (UN 3480/3481); excludes lithium metal batteries |
| Status | In force | Recommendation paper (August 2026) |
What This Means, by Role
Shippers & Exporters
No rule change yet — SP188 packaging, testing and marking obligations stand as-is. CINS’s push for universal declaration is one to track regardless.
Freight Forwarders & NVOCCs
Non-Vessel Operating Common Carriers (NVOCCs) and other forwarders should consider whether booking systems can already flag cumulative battery mass per container, ahead of any threshold becoming mandatory.
Ocean Carriers & Ship Officers
The Godavari case is the reference incident for this accumulation risk, and a reasonable benchmark for reviewing internal SP188 acceptance and consolidation practices now.
Terminals, Ports & CFS Operators
CINS is focused on what accumulates inside one box rather than on any single shipment, which bears on how consolidated battery cargo gets screened.
Insurers & P&I Clubs
CINS names insurers explicitly as an audience for this paper — its framing of accumulated risk is likely to feed into how these shipments get underwritten.
Action Items to Consider Now
For Freight Forwarders
- Add a “Total Net/Gross Battery Weight per Container” field to booking software, so master-carton aggregation is calculated automatically at load-planning stage rather than caught after the fact
- Request test reports and SP188 compliance certificates for every consolidated battery booking, not only spot checks
- Flag consolidations approaching CINS’s suggested 20 kg/CTU figure for extra scrutiny
- Watch for updates to CINS’s incident data and any follow-up guidance
For Vessel & Fleet Managers
- Review SP188 acceptance and consolidation practices against the Godavari case now
- Confirm firefighting capability for lithium-ion container fires — water mist lances, adequate CO2/dry-chemical stock for a 40-foot box
- Avoid direct-sun deck stowage for known or suspected battery consolidations where operationally possible
- Brief masters and crews on EmS fire-schedule consultation for suspected undeclared battery fires
- Consider an internal declaration requirement now, as Sea Consortium did after 2020
The Code Sets a Floor, Not a Ceiling
SOLAS Chapter VII makes the IMDG Code mandatory, but it sets a minimum. Nothing in SOLAS or the Code stops a carrier or shipper from adopting CINS’s recommended controls voluntarily, ahead of any future Code amendment. Sea Consortium, the Godavari’s manager, did exactly that after the fire — briefing the master on documentation requirements, requiring charterers to confirm shippers had properly declared contents, and circulating the incident fleet-wide. The Code required none of it.
