Every shape and size we press
Eight shapes, 26 sizes, and any size on custom order. Cubes are counted per kilogram at packing; the extrusion profiles share one size list because the factory cuts all three on the same dies. Dimensional tolerance is ±0.3 mm per side throughout.
The roster
26 sizes have their own page so far. The rest are listed with the roster facts we hold and get a page as it is written — a card without a link is a size you can order today, not one we are unsure about.
Cube
22, 25, 26, 27, 28 mm
Counts run in the same order as the sizes. Nominal packing count, counted at factory packing.
Cube with hole
26, 30 mm
A centre-hole cut of the cube. P28 records the two sizes and no counts, and neither size inherits the plain cube’s packing box.
Hexagonal
20×50, 20×35, 21×50, 22×50, 22×35 mm
Six flat faces cut into the extrusion. Read across the flats, then the length.

Stix / finger
20×50, 20×35, 21×50, 22×50, 22×35 mm
The factory catalogue name for this profile is “stix”. Stick and finger are the trade names for the same coal. Round in section: read the diameter, then the length.

Octagonal
20×50, 20×35, 21×50, 22×50, 22×35 mm
Eight flat faces rather than six — the same extrusion and the same size list as the hexagonal.

Flat / brix
25×25×15, 25×25×17 mm
Two heights on one footprint. Flat and brix are the same shape under both of the market’s names.

|---|---|
| 25 × 25 × 15 mm | On request |
| 25 × 25 × 17 mm | On request |
Dome
20×35 mm
A curved upper face on a flat base, so it seats on one plane.

| 20 × 35 mm | On request |
Lotus (3 leaves)
15×25 mm
A three-leaf pressing, and the second shape on this roster with a recorded count. The name is a shape, not the heat-management device the trade calls a lotus.
| Size | Pieces per kg |

| 15 × 25 mm | 72 — nominal |
How to read a card
Each size page carries one table, and every row names the block the figure comes from. That is the whole convention, and it exists because the numbers in this trade travel without their sources: piece counts get quoted as guarantees, box dimensions get carried across from a neighbouring size, and payloads get inferred from the size above.
So a cell either names its source or says not recorded. Nominal packing count means counted at the factory as the boxes are filled — first-party, and still nominal, because it moves with density and moisture on the day. Where a master carton or a house-box format is not on our sheet for a size, the card says so rather than showing the dimension from the size above it. Cube 22 and cube 27 have no recorded master carton; cube 22 has no recorded 20 ft payload. Those are three empty cells we could fill plausibly and do not.

1 × FCL (20 ft or 40 ft), and minimum 2 tonnes per shape, size and packaging variant inside it — so a container can be split across sizes as long as each variant reaches two tonnes. A 40 ft loads 26.5 t whatever the shape, because it weighs out before it cubes out; a 20 ft fills by volume, which is why its payload differs by size. Full working: wholesale pricing and container economics. The product behind every card, with its measured specification and commercial terms, is described in coconut shell charcoal briquettes, wholesale from an Indonesian factory.
Catalogue questions
- How many shapes and sizes can I actually order?
- Eight shapes across 26 sizes, and any size on custom order. Cube runs 22 to 28 mm; the three extrusion profiles — hexagonal, stix and octagonal — share one list of five sizes; flat/brix has two thicknesses; cube-with-hole, dome and lotus have their own.
- Why do some sizes show a piece count and others say "on request"?
- Because we publish the counts we actually record at packing. Cube is counted for all five sizes and lotus for its one; for the rest the count exists but is not on our data sheet, so the desk gives it rather than this page guessing it.
- Is the piece count a guarantee?
- No — it is a nominal packing count. It moves with density and moisture on the day the boxes are filled. Dimensional tolerance is ±0.3 mm per side.
- Does the price change with shape or size?
- No. Price follows the grade, which is an ash band, and the packaging — boxed or bulk. Shape and size change how much fits in a container, not the figure per tonne.
- What is the smallest order per size?
- One full container overall, and two tonnes per shape, size and packaging variant inside it. So you can split a container across several sizes as long as each reaches two tonnes.
- Can I mix sizes in one container?
- Yes, subject to the two-tonne minimum per variant. Mixing changes the payload: a 20 ft fills by volume, so the densest packing sets the tonnage, while a 40 ft weighs out at 26.5 t whatever the shape.
