Shipping Coconut Charcoal as Dangerous Goods: UN 1361, IMDG Amendment 42-24 and SP 978 (2026)

The 2026 reality in three sentences

Coconut shell charcoal moves by sea as UN 1361 CARBON, Class 4.2, a substance liable to spontaneous combustion.

The route by which a shipper could test charcoal out of the dangerous goods regime under the self-heating test (Special Provisions 925 / 223) ended on 1 January 2026, when IMDG Code Amendment 42-24, adopted by IMO Resolution MSC.556(108), became mandatory.

Special Provision 978 now sets the conditions under which charcoal is carried — weathering, packing temperature and headspace — and it is a set of carriage conditions, not an exemption.

What changed with Amendment 42-24

Before 2026, much charcoal moved as general cargo on the strength of a self-heating test report. That route is closed. The table summarizes the practical difference for a shipper in Semarang.

"UN 1361 certified" doesn't exist

UN 1361 is a transport classification: a four-digit UN number assigned to carbon of animal or vegetable origin. No laboratory or authority issues a certificate for it, so a supplier cannot be certified to it. When a supplier uses that wording, ask what document they actually mean.

What a supplier can legitimately show is evidence that the cargo is classified, prepared and packed correctly: a Dangerous Goods Declaration naming UN 1361, a weathering certificate, a safety data sheet with transport information in section 14, vanning survey records with temperature readings and photos, and a laboratory COA for the product itself.

SP 978 conditions in practice

Special Provision 978 turns into concrete steps on the packing floor and at the container. Each condition has an evidence document the carrier or buyer can ask for.

The DG document stack

A charcoal container leaves Semarang with a set of documents that must agree with each other. Inconsistent dates or weights between them are a common reason for a carrier to hold a booking.

Carriers that accept charcoal

Carrier stances change quickly and differ by trade lane. These are the carriers we book charcoal with; the factory reports the same document request across them: DGD, weathering certificate, SDS and vanning records. Acceptance still depends on lane, vessel and written DG approval. Ask us for the current position on your lane before booking.

When a booking is rejected

In the first 48 hours, get the reason in writing from the carrier's DG desk, check it against the DGD and weathering certificate, and tell the buyer. Do not re-submit the same booking unchanged to another branch office.

Common causes are a missing or inconsistent DGD, weathering dates that do not meet SP 978, a missing SDS section 14, a lane or vessel that does not accept Class 4.2, and declared weights that differ between documents.

Rebooking order: correct the documents and re-submit to the same carrier; if the carrier does not accept Class 4.2 on that lane, book an alternative carrier that does; adjust the sailing date only after the documents are fixed.

Container loading and tonnage

Payloads below are by format. Cubes pack densely; Hexagonal carries 17 t per 20' and 25.5 t per 40'.

Stuffing rules

• Load only charcoal that has completed weathering and is at or below 40 °C.
• Keep at least 30 cm of headspace below the container roof.
• Use a clean, dry container with no holes or residue.
• Record temperatures and take photos during stuffing for the vanning survey.
• Factory maximum: 15 cartons high, reduced where necessary to preserve at least 30 cm headspace and meet the carrier-approved stowage plan. Confirm dunnage with the carrier before loading.

Incoterms for DG cargo

We quote FOB Semarang. The table shows how responsibility for the dangerous goods booking and paperwork shifts under the three terms buyers ask about most.

Transit times from Semarang

Indicative port-to-port days, depending on carrier, transshipment and season. Owner-confirmed planning ranges; confirm the sailing schedule with the carrier before booking.

How we verify

We check regulatory facts against the regulator's own text first (IMO, EUR-Lex, national customs and standards bodies), then carrier advisories, then forwarders. Each fact carries the date it was last verified. Shipping content is reviewed every 6 months, or sooner when a rule changes.
