Shipping Coconut Charcoal as Dangerous Goods (UN 1361): The 2026 Compliance Hub

By Mohamad Sinno, Charcoal Expert · Reviewed by Budi Hartanto, shipping specialist, 25 years in forwarding as of 2026 · Last updated 29 July 2026

The 2026 reality in three sentences

Coconut shell charcoal ships as UN 1361, CARBON of animal or vegetable origin, Class 4.2, PG III. Since IMDG Amendment 42-24 took force on 1 January 2026, no test result takes it outside the Code. SP 978 sets conditions instead; the binding one is timing — the weathering clock runs from production, not booking.

Those dates come from the instrument itself: the amendment was adopted by IMO Resolution MSC.556(108) on 23 May 2024, deemed accepted on 1 July 2025, and entered into force on 1 January 2026, with voluntary application allowed from 1 January 2025. Much of what still ranks for this question was written before that date and reads in the future tense.

PT. Coco Reina Global Charcoal Indonesia declares and ships its coconut shell charcoal briquettes as UN 1361, Class 4.2, packing group III. It holds unpacked material for at least 14 days after production before packing, and at least 28 days in total from raw-material receipt to container stuffing. It packs at a measured material temperature of 20–30 °C, against the 40 °C day-of-packing ceiling Special Provision 978 sets. Everything below is the sequence that produces those numbers, and the places it breaks.

What changed with Amendment 42-24

Amendment 42-24 withdrew the special provisions that let a charcoal consignment test its way out of the IMDG Code and replaced them with SP 978, which sets conditions for carrying the cargo rather than a route around it. The change followed a fire record: CINS members recorded at least 68 fire incidents on board ships between January 2015 and December 2022 — data CINS describes as incomplete, and which exclusively involved charcoal produced as fuel, most of it misdeclared (CINS, September 2024).

Regulatory position last verified 29 July 2026 against Resolution MSC.556(108).

Before: a passed self-heating test could keep a charcoal consignment outside the Code

Under the previous regime a consignment that passed the UN N.4 self-heating test could be carried outside the Code's dangerous-goods requirements, under special provisions 925 and 223. Both were removed and replaced by SP 978; CINS records that the two had let shippers seek acceptance of charcoal outside the full application of the Code (CINS, September 2024).

After: SP 978 sets conditions of carriage, not a way around it

SP 978 states that the UN N.4 test shall not be used to exempt UN 1361 from the Code, that without testing the material is assigned to at least packing group III, and — unless the competent authority approves otherwise — that unpacked material is weathered under cover in the open air for a minimum of 14 days before packing, or steamed, cooled and packed under an inert gas atmosphere and held at least 24 hours. It caps material temperature at 40 °C on the day of packing, and requires a minimum 30 cm headspace in the container. For the clause itself, what the test still decides and what it never certified, see how Class 4.2 and Special Provision 978 now apply to UN 1361 charcoal.

What Amendment 42-24 did not change

It changed the route out of the Code, not the classification. Charcoal was Class 4.2 before the amendment and remains Class 4.2 under it, and the product did not become more hazardous on 1 January 2026. The amendment does not set any carrier's commercial acceptance policy, and nothing in it makes a consignment or a producer "certified" — UN 1361 is a transport classification, and there is no certificate behind it.

The compliance workflow, origin to vessel

Shipping charcoal compliantly is a six-step sequence that starts at the kiln and ends at the vessel. Each step produces a document the next step depends on, and the rules behind those steps come from three different places — the Code, industry guidance, and the individual carrier. This page ends at the vessel; it describes how Coco Reina's coconut shell charcoal briquettes reach it.

Steps 1–2: classify the cargo, then start the weathering clock

The weathering period runs from the day the material is produced, not from the day a container is booked. Whether a shipment can be compliant is therefore settled weeks before it is scheduled — a booking cannot buy back a period that was never run.

Our regime is two-stage and the stages do not overlap: raw material cures at least 14 days before processing, and finished material is held at least 14 days after production before stuffing — at least 28 days in total. Production lead time is 15 working days for a 20 ft and 20 for a 40 ft, excluding packaging, QC and vessel booking, which is the window the clock has to sit inside. Loading is from Jakarta (Tanjung Priok) as the primary port, with Semarang also used. Charcoal is also traded under other names, and CINS records the concern that these may conceal the true nature of the cargo (CINS, September 2024, section 1.3) — which is how misdeclared consignments reach ships whose crews do not know what they are carrying; the classification above is what goes on the paperwork.

Steps 3–4: build the document set, then get the booking approved

The document set is built at origin and has to agree with itself: the declaration, the weathering statement, the safety data sheet and the bill of lading all describe one shipment, and a disagreement between any two of them is what a dangerous-goods desk rejects. Amendment 42-24 added three entries to the transport document for UN 1361 — date of production, date of packing, and material temperature on the day of packing — and those come off the factory's batch log rather than being estimated at booking.

Per shipment we issue the export declaration, commercial invoice, packing list, bill of lading, certificate of origin, safety data sheet, dangerous goods declaration, the SP 978 weathering and packing-temperature statement, and a per-batch lab report. The weathering certificate is issued on Coco Reina letterhead and signed by Mohamad Sinno. On the bill of lading the cargo description reads UN 1361, CARBON, ANIMAL OR VEGETABLE ORIGIN (coconut shell charcoal), Class 4.2, PG III, as it appears on the bill of lading. For what each document proves and who issues it, see the DGD, weathering statement, MSDS, survey and certificate of origin, document by document.

We have moved UN 1361 full container loads with four lines: MSC from Jakarta and Semarang, and Maersk, CMA CGM and PIL from Jakarta. That is a shipping record, and it is a different statement from the approval status further down — the two lists answer different questions. On how a line's review works, see getting a charcoal DG booking approved with an ocean carrier.

Steps 5–6: stuff the container below the temperature limit, then survey it

Charcoal may be packed only when the material's own temperature is at or below 40 °C on the day of packing. We measure it each stuffing day and record 20–30 °C, which is the margin the declaration reports rather than a limit restated. Headspace of at least 30 cm is maintained in the container, with the stow geometry SP 978 sets; the detail sits with stuffing the container, choosing the incoterm and costing the sea leg. A vanning survey then records the stuffed container. We supply the weathering record and the vanning survey to buyers on request.

Which of these requirements are Code text, which are industry guidance, and which are one carrier's policy

Requirements quoted for charcoal shipments do not all carry the same weight, and pages that run them together leave a shipper unable to tell what is negotiable. Treating guidance as law means over-documenting; dismissing a carrier requirement as "only guidance" loses the booking.

When bookings go wrong

Most of what is written about Class 4.2 self-heating cargo concerns the fire at sea. That is the underwriter’s failure case. The one a shipper actually meets is a booking refused at document review, with the container standing while the paperwork is rebuilt — which is why charcoal sea freight compliance is a documentation discipline before it is a safety one.

Anatomy of a refused charcoal booking

In December 2025 one of our bookings was rejected for an incomplete weathering certificate. The certificate was completed and resubmitted, and the booking cleared in one day. The carrier stays anonymous.

The date is the part worth reading twice. December 2025 is before 1 January 2026, so this refusal did not come from the Code — it came from a carrier enforcing ahead of it. That was not unusual: Hapag-Lloyd required full dangerous-goods compliance for charcoal from 1 April 2025, and Maersk’s Philippines customer advisory stopped accepting non-DG charcoal bookings from 1 October 2025. A shipper reading only the Code's mandatory date would have been nine months behind the earliest of them.

It cleared in a day because the certificate was incomplete — a document defect, and documents can be re-issued. Had the weathering period been short, nothing could have been re-issued, because the clock runs from production. That is the distinction the table below is organised around, and it is the one that decides whether a refusal costs a day or a month.

Read the two tiers differently. The carrier rows are acceptance conditions those lines publish, so they are grounds a booking is actually refused on. The Code rows are requirements: a file missing them is incomplete on its face, and no source says which line refuses on which. Carrier positions also move — re-confirm the current requirement with the line before booking.

Compliance is not acceptance: the second gate

A charcoal consignment that meets every IMDG requirement can still be refused. Acceptance is a commercial decision each line makes on top of the Code, and the conditions differ line by line: one requires the shipper to be pre-audited before it will take the booking at all (Maersk Philippines advisory, 1 October 2025), another refuses charcoal offered in bulk without packaging (Hapag-Lloyd, in force from 1 April 2025). Meeting SP 978 is necessary, not sufficient.

Nothing in the Code creates a pre-audit requirement, yet Maersk's Philippines customer advisory (effective 1 October 2025) makes approved- shipper status a precondition of booking at all. We hold approved-shipper status with four lines: MSC from January 2026, CMA CGM from January 2026, Maersk from March 2026 and PIL from June 2026. That is an approval status granted by each line separately — it is not a certification, and it says nothing about any line we have not named. The full picture, line by line with each verification date, sits with the carriers hub.

What a refused booking costs while it is being fixed

Most of the cost is schedule. The container waits, storage and detention accrue, and the next vessel may be a week out. Those costs are recoverable in the sense that a document can be re-issued and the box can sail — our December 2025 case cleared in a day, though a one-day recovery is that case's figure and not a promise. A weathering shortfall is different: the period cannot be re-run inside a booking window, so the shipment waits for the material rather than for the paperwork. That is the failure worth designing against, and it is designed against at the kiln, not at the port. For the line-by-line picture with each verification date, and what to do once a booking has already been refused, see which lines accept charcoal, and the recovery route after a refusal.

Shipper FAQ

Is coconut shell charcoal treated differently from any other charcoal?

No. The Dangerous Goods List entry for UN 1361 names coconut shell alongside bone, bamboo, jute and wood as source materials for the same entry, so the classification, the weathering condition and the packing-temperature limit apply identically. What differs is commercial, not regulatory: origin, and which lines will book it.

Who signs the dangerous goods declaration, and what does signing it mean?

The shipper signs it. The signature states that the consignment is classified, packed, marked and labelled correctly and is fit for carriage. It is not a formality a forwarder absorbs: the liability sits with whoever signed, which is why the production and packing data on it must come from a record rather than from memory.

Does the incoterm decide who carries the dangerous-goods obligation?

It decides who arranges and pays for carriage, not who is the consignor of dangerous goods. Classification, weathering and the declaration stay with the party offering the goods for transport, whatever term is agreed. We offer EXW Factory as the default and CFR on some orders.

How can a buyer verify a supplier actually ships charcoal compliantly?

Ask for documents rather than assurances: a recent dangerous goods declaration, the weathering statement with its production and packing dates, the safety data sheet, and a vanning survey report. We supply the weathering record and vanning survey on request. A supplier who describes charcoal as outside the Code is describing a regime that ended on 1 January 2026.

Can a charcoal sample go by air instead?

Not as a way around the classification. The Dangerous Goods List entry for UN 1361 carries a limited quantity of 0 and an excepted quantity of E0, so neither of the small-quantity routes that exist for many substances is available. Air carriage sits under a different instrument from the IMDG Code and we have not verified its charcoal provisions here — confirm the route with a dangerous-goods forwarder before assuming a sample can fly.

How do I find out when these rules change again?

Amendment 42-24 carried a voluntary period before its mandatory date — adopted May 2024, applicable voluntarily from January 2025, in force January 2026 — so the Code side gave a year of notice. Carrier policy moves faster and with less, as the December 2025 refusal above shows. Both are tracked in the dated radar of charcoal shipping and import rule changes.
