CRITICAL REGULATORY CHANGE — EFFECTIVE 2026
Under IMDG Code Amendment 42-24, all charcoal shipments by sea must be classified as Dangerous Goods (UN 1361, Class 4.2) from January 1, 2026. Major carriers including Maersk, Hapag-Lloyd, and CMA CGM are already enforcing these rules in 2025. Non-compliant charcoal packaging export will be rejected at port.
Charcoal packaging for export has changed fundamentally. Between 2015 and 2022, 68 container fires were linked to charcoal shipments — prompting the IMO to eliminate all previous exemptions. Every bag of charcoal loaded for sea transport is now classified as Dangerous Goods. This means UN-approved packaging, mandatory thermal jackets, weathering certificates, and Dangerous Goods Declarations. Get the charcoal packaging export wrong and your container gets rejected at port, delayed, or worse — hit with a $15,000 mis-declaration fee. This guide covers exactly what you need to know for compliant charcoal shipping in 2026.
What Changed: SP 925 and SP 223 Are Gone. Before 2026, charcoal exporters could use Special Provisions SP 925 and SP 223 to exempt shipments from Dangerous Goods classification — provided the charcoal passed the UN N.4 self-heating test. In practice, this created a loophole: shippers declared charcoal as non-DG cargo, bypassing safety controls entirely. The 68 container fires between 2015 and 2022 proved this system failed. IMDG 42-24 removes both exemptions permanently and replaces them with SP 978 — no test result can exempt charcoal from DG classification.
IMDG Code 42-24: Charcoal Export Packaging Rules
Special Provision 978 (SP 978) is the new regulation governing all charcoal packaging export by sea. Here are the mandatory requirements:
1. DG classification is mandatory. All charcoal must be declared as UN 1361 / Class 4.2 (CARBON, animal or vegetable origin). The old exemptions under SP 925 and SP 223 have been removed. The UN N.4 self-heating test can no longer be used to exempt charcoal from DG classification.
2. Pre-shipment treatment (two options):
Option A — Weathering (14 days): After production, store unpacked charcoal under cover in open air for minimum 14 days before packaging. No special equipment needed. This is the standard method for most Vietnamese exporters.
Option B — Inert gas (24 hours): After pyrolysis, apply steam and cooling to the unpacked charcoal, then pack under inert gas atmosphere (e.g. nitrogen). Packages must be stored under loose cover or in open air for minimum 24 hours before transport. Requires nitrogen injection equipment — used mainly by large-scale industrial operations.
Both options require charcoal temperature ≤40°C on the day of packing.
3. Temperature limit: ≤40°C. Charcoal must not exceed 40°C on the day of packing into packaging. Temperature must be documented and photographed.
4. UN-approved packaging only. Packing instruction P002 applies. Allowed: UN-approved boxes, bags, and drums. Not allowed: packing types 4H1, 5H1, 5H2, 5L1, 5L2, 5M1. Regular PP bags without UN certification are no longer acceptable for charcoal packaging export.
5. Container stowage rules. Minimum 30 cm headspace must be maintained in the container. Stowage height must not exceed 1.5 m, or maximum block size 16 m³ with minimum 15 cm space between blocks.
6. Vacuum thermal jacket is mandatory. Every container must be completely vacuum-packed with a thermal jacket. This prevents condensation and self-heating during transit. Cost: approximately $280–400 per container (7–10 million VND). Maersk-recommended suppliers include Inthermax (Octoliner), Signode (Vapor Vac), and SAR International (RuggedPro).
Required Documents for Charcoal Packaging Export
Shipping lines now require extensive documentation before accepting charcoal bookings. Based on Maersk’s October 2025 requirements (which other carriers are adopting), you need:
Before container release:
1. Preliminary Dangerous Goods Declaration (DGD)
2. Material Safety Data Sheet (MSDS) — must indicate charcoal usage and be issued by the manufacturer
Before container gate-in at terminal:
1. Final Dangerous Goods Declaration (with correct UN packing code)
2. Weathering Certificate — on manufacturer letterhead, dated and signed, with: production date, weathering start/end dates, packaging dates, cargo temperature during packing, charcoal type and particle size, photos of weathering and packaging process
3. Vanning Certificate — from carrier-nominated surveyor only. Must include: container stuffing photos, cargo and ambient temperature readings, thermal jacket in fully vacuumed condition, door-shut photos with visible seal number
4. Material Safety Data Sheet (MSDS)
Additionally, the Multimodal Dangerous Goods Form (MDGF) must be submitted with full details, signed, and stamped at least 48 working hours before cut-off time. Mis-declaration penalty: $15,000 per container.
Approved Charcoal Packaging Export Types (P002)
Under packing instruction P002, only UN-approved packaging is permitted. Here are the compliant options for charcoal packaging export:
| Packaging Type | Weight Options | Best For | Pros | UN Code Required |
| UN Bags (PP woven) | 5/10/15/20 kg | Wholesale, distributors | Cost-effective, water-resistant | 5H3 or 5H4 |
| UN Boxes (cartons) | 3/5/10/15 kg | Retail, private label | Premium look, printable | 4G or 4GV |
IMPORTANT: Packaging types 4H1, 5H1, 5H2, 5L1, 5L2, and 5M1 are explicitly prohibited for charcoal packaging export. All packaging must be new, airtight, intact, and carry the UN certification mark.
For most B2B charcoal export, UN-certified PP woven bags (5–20 kg) remain the practical standard. For retail and private label, UN-certified carton boxes with full-color printing. Your packaging supplier must provide UN test certification proving the packaging meets P002 requirements.
Container Loading Capacity Under New Rules
The 1.5 m stowage height limit and 30 cm headspace requirement significantly reduce loading capacity compared to pre-2025 practices. Here’s what you can realistically fit in a 40HQ container with compliant charcoal packaging export:
| Product | UN Bags (PP) | UN Cartons | Notes |
| Mangrove lump | 25–27 tons | 25–27 tons | Dense, heavy product |
| Longan/Khaya lump | 20–22 tons | 20–22 tons | Similar to mangrove |
| Sawdust briquettes | – | 22–27 tons | Uniform shape, efficient stacking |
| Binchotan | 20–24 tons | 20–24 tons | Light, usually in cartons |
| Bamboo charcoal | 16–23 tons | 16–23 tons | Lighter than hardwood |
| Coffee/Eucalyptus | 18–24 tons | 18–24 tons | Softwood, lighter density |
These numbers account for the 1.5 m height limit and thermal jacket space. Actual loading depends on charcoal piece size, bag dimensions, and stacking method. Your vanning surveyor will confirm compliance during stuffing.
Moisture Protection for Charcoal Packaging Export
Moisture control is now both a safety requirement and a quality issue. Self-heating from moisture was the root cause of the 68 container fires that triggered the new regulations. Here’s the complete moisture protection protocol for charcoal packaging export:
1. Pre-loading moisture test. Charcoal must be tested at <5% moisture before packing. Document the test results — this goes into the weathering certificate.
2. Vacuum thermal jacket. Mandatory under Maersk and most major carriers. The thermal jacket lines the entire interior of the container and is vacuum-sealed, eliminating air circulation that causes condensation. Cost: approximately $280–400 per container (7–10 million VND). This is the single most effective protection measure.
3. PE inner liner in every bag/carton. Each individual UN-approved bag or carton should contain a polyethylene inner liner for direct product protection.
4. Desiccant strips. Place 8–12 calcium chloride desiccant strips inside the container, hung from lashing rings. Cost: $30–50 per container.
5. Container inspection. Before loading, inspect for holes, rust, and residual moisture. The packaging and interior atmosphere must be clean and odorless with no presence of fumes or smoke. Cargo temperature must not exceed ambient temperature by more than 5°C.
Private Label & Labeling Requirements
Charcoal packaging export now requires dual compliance: trade labeling (brand, weight, origin) AND dangerous goods labeling (UN mark, DG class, placard). Every package must display:
DG marking: UN 1361, CARBON label, Class 4.2 diamond label on every bag/carton. DG placards on all 4 sides of the container.
Trade labeling: Product name, net weight, wood type (botanical species for EU, e.g., Rhizophora apiculata for mangrove), country of origin (“Made in Vietnam”), manufacturer name, batch/lot number, FSC logo if certified.
EU-specific (EN 1860-2): Flame icon crossed by kitchen fork, warning text “Do not light indoors,” material composition, symbols minimum 6 mm (retail) or 10 mm (industrial).
Private label MOQ: Typically 1×40HQ for custom packaging. Arabic/English bilingual packaging for UAE/GCC, Japanese for Japan, Korean for Korea. Allow 7–10 extra days for first-run custom production.
What Major Carriers Require for Charcoal Packaging Export
Each shipping line has specific requirements beyond the IMDG baseline. Here’s what the major carriers demand:
Maersk (from October 1, 2025): Only DG bookings from pre-audited shippers. Vacuum thermal jacket mandatory (from Maersk-recommended suppliers only: Inthermax, Signode, or SAR International). Vanning survey by Maersk-nominated surveyors only. No non-DG charcoal bookings accepted. No shisha/hookah charcoal from Vietnam.

Frequently Asked Questions
Q: Is charcoal classified as dangerous goods for shipping?
Yes. From January 1, 2026 (mandatory), all charcoal must be declared as Dangerous Goods under UN 1361, Class 4.2. Major carriers like Maersk and Hapag-Lloyd are already enforcing this from 2025. The old exemptions under SP 925 and SP 223 have been permanently removed.
Q: What packaging is required for charcoal export?
UN-approved packaging per IMDG packing instruction P002. This includes UN-certified bags, boxes. Regular PP bags without UN certification are no longer accepted. Packaging types 4H1, 5H1, 5H2, 5L1, 5L2, and 5M1 are explicitly prohibited.
Q: What is a weathering certificate for charcoal?
A document from the charcoal manufacturer confirming that after production, the unpacked charcoal was stored under cover in open air for minimum 14 days before packaging. It must include production dates, weathering dates, packaging dates, cargo temperature, and photos of the process.
Q: Is a thermal jacket mandatory for charcoal containers?
Maersk requires vacuum thermal jacket on every charcoal container from October 2025. Other carriers are expected to follow. The jacket costs approximately $280–400 per container (7–10 million VND). Approved suppliers include Inthermax (Octoliner), Signode (Vapor Vac), and SAR International (RuggedPro).
Q: What happens if charcoal is shipped without DG declaration?
Carriers impose a mis-declaration fee of $15,000 per container. The container will be held at port, potentially rejected, and you may be blacklisted from future DG bookings. Under the new rules, there is no legal way to ship charcoal as non-DG cargo by sea.
Q: Can charcoal be shipped under a different product name to avoid DG rules?
No. Carriers now implement cargo screening and Know Your Customer (KYC) verification. Charcoal traded under alternative names to conceal its dangerous nature will be flagged. If undeclared charcoal is discovered during transit or at destination, the shipper faces a $15,000 mis-declaration fee, container detention, and blacklisting from future DG bookings.
