What shipping a container of charcoal involves
Three things decide whether a container of charcoal moves: how it is classified, how it was prepared before it was packed, and which documents travel with it. The first two are one regulation, and it changed. The third is what a buyer can check.
§1 · Classification, preparation, paperwork
Charcoal is not an ordinary dry cargo by sea. It moves under a named entry in the maritime dangerous-goods code, and the conditions attached to that entry were rewritten recently enough that a good deal of trade guidance still describes the old ones. What shipping as UN 1361, Class 4.2, packing group III, now requires of a producer is the page under this one.
Preparation is the part that costs something. The code sets conditions on how the material is handled between the kiln and the container, which means a production schedule either has room for them or does not. Paperwork is the part you can audit without visiting anyone: a document that should exist and does not is the earliest signal available that something upstream was skipped.
§2 · The documents that travel with a container
Three of these come from someone independent of us, which is what makes them worth asking for by name. Which of them your destination requires is a question for your broker; this is the pack a container of charcoal generally moves with.
| Document | What it establishes | Who issues it |
|---|---|---|
| Commercial invoice and packing list | What the goods are declared as, and the tariff line they are declared under. | Us, per shipment |
| Certificate of origin | Where the goods were produced. | Chamber of commerce at origin |
| Dangerous goods declaration | That the shipment is declared under the entry in the maritime code, with its class and packing group. | Us, per shipment |
| Weathering certificate | That the batch was weathered before it was packed, dated to the batch. | The producer, or the surveyor who attended |
| Vanning survey | How the container was stuffed, against the stowage figures the carrier works to. | An independent surveyor |
| Certificate of analysis | The measured values for your lot, with the test method and the issuing laboratory named on it. | The laboratory |
| Bill of lading | The contract of carriage, and the cargo description the carrier accepted. | The carrier |
§3 · The pages under this one
The entry, the provision that replaced the old exemptions, the four things a producer now has to do, and the three documents to ask a supplier for: what changed in the dangerous-goods code, and what to ask your supplier. That is the page to read before your next booking, and it is the one that explains why the weathering certificate in the table above exists at all.
The tariff line is a separate question with a separate answer. We declare 4402.20.10, and the subheading it sits under was added to the nomenclature in 2022 — which is recent enough that a good deal of the trade, including us until this year, was still using the code that preceded it. What changed, what your own line probably is, and what the four documents have to agree on is the other page in this section.
§4 · The limits of what is in this section
Classification for any given consignment is the shipper's and the carrier's determination, and nothing in this section is a determination of yours. We describe the maritime code; road and rail regimes have not embedded the same conditions. What this site does and does not claim — including on dangerous-goods classification — sets the limits out in full and governs every page here.

§5 · What supports the above
| Claim | What supports it | How we state it |
|---|---|---|
| Charcoal moves under a named dangerous-goods entry in the maritime code. | The entry and its conditions are published. The provisions are named on the page under this one. | Stated as fact. |
| The documents in §2 are the ones that travel with a container of charcoal. | How our own shipments are documented. | Stated as fact about our process. Which documents a given destination requires is your broker's answer rather than ours, and §2 says so. |
| A document that should exist and does not is a signal about the supplier. | Our reasoning, not a rule. | Our assessment. §2 names who issues each document so that you can check rather than take our word for it. |
§6 · Before any of this matters
None of it needs settling before you have burned the cube, and the document pack is agreed in the contract rather than at the port — how an order works end to end covers that sequence.
