Booking Charcoal with Ocean Carriers: Who Accepts It and How to Get Approved

By Mohamad Sinno, Charcoal Expert · Reviewed by Budi Hartanto, shipping specialist, 25 years in forwarding as of 2026 · Last updated 3 August 2026

Coconut shell charcoal moves by sea only as declared dangerous goods. Which shipping lines accept charcoal turns on where it loads — Maersk's shisha-charcoal refusal names Vietnam and China, not Indonesia. This is the carrier layer of how charcoal actually moves from an Indonesian factory to a destination port: who accepts, on what dated conditions, and what DG booking approval takes.

The acceptance landscape, dated

As of July 2026, four ocean carriers still take Indonesian coconut shell charcoal FCL — Maersk, MSC, CMA CGM and Hapag-Lloyd — each on its own pre-audit and documentation conditions. The rest of the audited set is either origin-restricted, closed to fuel-grade charcoal, publishes nothing retrievable, or publishes only undated, pre-amendment material.

Where the container loads changes the answer

Carrier charcoal policy in 2026 is written per country of loading, so an origin-blind list inverts two rows for an Indonesian shipper. Ocean Network Express (ONE) lists, under UN 1361, "Charcoal from Indonesia is prohibited" (DG House Rule V5.0, 15 May 2026). Maersk runs the opposite way, refusing shisha, hookah and waterpipe charcoal only "From Vietnam and China," and Indonesia is not on that exclusion list (advisory effective 1 October 2025). A carrier table with no origin column gets both backwards.

Carrier-by-carrier stance for Indonesian charcoal FCL

The table gives each carrier's published stance on charcoal loading in Indonesia, the conditions attached, the carrier document it comes from, that document's date, and the date the row was last verified. Where a carrier publishes nothing retrievable, the row says so rather than guessing.

This is a snapshot of a fast-moving set of policies. For the maintained per-line detail, see the full living list of carrier stances with each verification date, refreshed on a shorter cycle than this page.

How to re-check any carrier acceptance claim, including this one

A carrier acceptance claim is only as good as three things: the carrier's own document behind it, the version and date printed on that document, and the date someone last opened it. Apply the test to any list you are handed — this one included.

1. Is the stance traced to the carrier's own advisory, house rule or prohibited-cargo list — not a third-party summary or a competitor's table?
2. Does that document carry a version number and a date? A house rule at V5.0 says something a V2.5 copy of the same rule does not.
3. When was the row last verified against the live document? Carrier charcoal policy is being revised on the order of months, not years.

This page re-verifies its carrier rows on a roughly 90-day cycle, and it dates each row twice on purpose: the advisory's own date and the date it was last checked. That is a commitment to a cadence, not a claim that the table is permanently correct. Policy movement between passes is tracked in the dated change log for charcoal shipping and trade rules.

Where the public record runs out

COSCO exposes no retrievable charcoal policy at all; ZIM's charcoal pages exist but are undated and predate 42-24. On cost, only Hapag-Lloyd names a figure: a Dangerous Goods Premium of USD 250 / EUR 210 per container (December 2025 advisory). No other audited carrier publishes a charcoal-specific surcharge in its primary sources — so treat that single number as one line's tariff, and get every other DG cost from a quote. What dangerous-goods status adds to a charcoal freight quote — surcharge, survey, jacket and payload loss — is its own breakdown.

The 2025 enforcement wave and what it means now

Carriers did not wait for the IMO deadline. IMDG Amendment 42-24 removed the exemption that let charcoal ship as non-DG on a passed N.4 test — Special Provision 978 states the N.4 test "shall not be used to exempt carbon of animal or vegetable origin (UN 1361)" (reproduced by CINS, September 2024) — and every major line rewrote its charcoal policy inside eighteen months, each setting its own enforcement date ahead of the mandate.

The dates each carrier set, ahead of the IMO deadline

Five carriers set four distinct enforcement dates between April and November 2025, all of them before the IMO's own mandatory date of 1 January 2026 — the earliest running nine months ahead. MSC and ONE landed on the same day; the rest are staggered.

1. 1 Apr 2025 Hapag-Lloyd full DG
2. 1 Jun 2025 CMA CGM SP 978
3. 1 Oct 2025 Maersk pre-audit
4. 1 Nov 2025 MSC + ONE
5. 1 Jan 2026 IMO mandatory

The stagger explains why the same shipper met different rules on different lines through 2025, why carrier pre-audit queues exist now rather than in January 2026, and why a carrier's silence was never permission — only a later start date.

Carrier documents still published today that describe the abolished route

A live URL is not a current rule. At least three carrier documents reachable today still describe the self-heating-test exemption or a pre-amendment charcoal category, and none reflects the rule in force. Quoting one of them to a booking desk costs a shipper credibility at the worst moment.

• ONE DG House Rule V2.5 (1 January 2024) — superseded. It still references the SP 925 exemption and "a total of 28 days" curing for a non-DG carbon route. Replaced by V5.0 (15 May 2026).
• CMA CGM / APL Prohibited List (4 December 2017) — superseded. It still lists "Non dangerous charcoal/carbon … REFUSED from Asian Area" — a category built on the pre-42-24 idea that charcoal could be non-dangerous at all.
• ZIM bulk-charcoal help page (undated) — treat as stale. It still contemplates a "Non-DG … Self-Heating Certificate Test report" route, i.e. the SP 925 logic 42-24 abolished.

Getting approved as a shipper

Carrier approval for charcoal is a standing shipper status granted after a factory-level audit and held separately with each carrier — not a form filed with each booking. Maersk accepts "only DG charcoal bookings from pre-audited shippers" and points shippers to the local Maersk office to obtain that status (effective 1 October 2025). Maersk is the only carrier in the audited set whose own advisory states a pre-audit requirement in those terms; treat any other line's process as something to confirm with its DG desk rather than assume.

The audits exist because of how charcoal fires start. Investigators have traced container fires to charcoal declared as "tablets for water pipes" or "hookah accessories" — trade names that hide a Class 4.2 self-heating cargo (Jensen Hughes; Gard P&I). The pre-audit is the carrier defending against exactly that concealment, which is why it inspects the factory rather than the paperwork alone.

What the carrier audit actually examines

A carrier charcoal audit tests four things a factory must be able to evidence on demand: the Dangerous Goods Declaration, the SDS/MSDS, the weathering certificate, and the vanning survey — checked against SP 978's operating conditions: 14-day weathering before packing, material ≤40 °C on the day of packing, and the 30 cm container headspace SP 978.6 requires whatever the packing approach (CINS, September 2024). The audit asks what the factory records, not what it promises. Each document, who issues it and which fields matter is set out in each document in the charcoal DG stack, who issues it and which fields matter.

What that looks like in practice, from this factory's own records: Coco Reina declares its coconut shell charcoal as UN 1361, Class 4.2, Packing Group III, in 4G fibreboard packaging, with Packing Group III assigned on SP 978's no-test default — "at least packing group III" without testing — and no separate classification test report held. Production date, packing date and packing-day material temperature are kept in the production batch log and entered on the DGD for each shipment.

What an already-approved factory saves the buyer

A buyer sourcing from a factory that already holds carrier approval books against an existing status instead of waiting out a separate audit cycle with each line. Two constraints are worth knowing before that helps: approval is per carrier, so a factory cleared with one line is not automatically cleared with another; and at least one line locks in its own suppliers — Maersk requires the thermal jacket from a Maersk-recommended supplier and accepts a vanning survey only from a Maersk-nominated surveyor, so "we have a surveyor" can still be the wrong surveyor.

The audit criteria are met with measured values, not intentions. Coco Reina runs a two-stage weathering regime — raw-material curing for at least 14 days before processing, then a post-production weathering hold of at least 14 days before container stuffing, at least 28 days in total from raw-material receipt to stuffing — and checks material temperature on each stuffing day, measured at 20–30 °C against SP 978's ≤40 °C limit. As a first-party record, this factory holds approved-shipper status with MSC and CMA CGM since January 2026, Maersk since March 2026, and PIL since June 2026, and has shipped UN 1361 FCL with MSC from Jakarta and Semarang, and with Maersk, CMA CGM and PIL from Jakarta. PIL is absent from the table above by design: shipping with a line is first-party experience, while a table row claims a carrier's published policy — which needs that carrier's own dated advisory, and no PIL source here supplies one.

Buyers planning a charcoal booking can request Coco Reina's DGD, weathering record and packing-temperature log to run against a carrier's audit — the same records a DG desk reviews. Reach the factory on WhatsApp at +62 821-3924-038.

The recovery case

A refused charcoal booking is usually recoverable, and what was missing decides how long it takes — a documentary gap closes far faster than a compliance one.

A rejected booking, recovered in one day: what was missing

In December 2025 one of this factory's bookings was refused on a single stated ground: the weathering certificate was incomplete. Nothing about the cargo changed — the charcoal had been weathered, the yard records existed, the certificate simply did not carry everything the DG desk needed to see. The factory completed and resubmitted it, and the booking cleared in one day.

Three things in that case generalise. The refusal came in December 2025 — before IMDG Amendment 42-24 became mandatory on 1 January 2026 — because the carriers were already enforcing ahead of the Code, which is the timeline set out above. The fix was documentary, not physical: the fastest recoveries are the ones where the compliance work was genuinely done and only the paperwork lagged. A booking refused because the weathering itself never happened cannot be recovered in a day, because the clock cannot be run backwards. And a documentary refusal lands before the box moves, not at the terminal gate: Maersk requires the DGD, weathering certificate, vanning certificate and MSDS before gate-in (effective 1 October 2025), so an incomplete file surfaces at booking review.

The general procedure behind a single recovery — diagnosis, document remediation, rebooking and realistic timelines — is set out step by step in the step-by-step recovery playbook for a refused DG booking.

When an approved lane still refuses the box

Carrier approval is not a guarantee of carriage. A partner line, feeder operator or term-charter vessel owner on the leg can refuse a charcoal container the contracting carrier has already accepted — Maersk's own advisory lists, among circumstances under which it will not accept charcoal, cases where "VSA (Partner) policy, TC vessel owner (term charter) / Feeder operator's policy prohibits." Approval clears the contracting carrier, not every vessel that might carry the box, so a booking rejection can still arrive on an otherwise-approved lane.

Questions carriers get asked before a charcoal booking

Is charcoal banned from ocean shipping now?

No. Coconut shell charcoal still ships by sea, but only as fully declared dangerous goods — UN 1361, Class 4.2 — and no longer as non-DG cargo. Some carriers refuse it entirely: Ocean Network Express prohibits charcoal from Indonesia (DG House Rule V5.0, 15 May 2026) and Evergreen bans fuel-grade carbon and charcoal (Prohibited List V35, June 2026). The four majors above carry it under pre-audit and documentation conditions.

Can my forwarder get carrier approval on my behalf?

No. Carrier charcoal approval is an audit of the shipper — the factory whose product loads the container — not of the forwarder. Maersk states only DG charcoal bookings from pre-audited shippers are acceptable and directs shippers to the local Maersk office for that status (effective 1 October 2025). A forwarder books against the shipper's standing status; it cannot substitute for it.

Does a passed self-heating test still let charcoal ship as non-DG?

No. Under IMDG Amendment 42-24, Special Provision 978 states the UN N.4 test "shall not be used to exempt carbon of animal or vegetable origin (UN 1361) from the provisions of this Code" (reproduced by CINS, September 2024). The self-heating test-out route was removed; any carrier page or supplier still offering it is quoting a superseded rule.
