Charcoal vs activated carbon: what Kora supplies

Searches for “coconut shell activated carbon” bring up a mix of makers, traders and charcoal sellers, and it is easy to send a request to the wrong one. We would rather help you avoid that. Kora Coconut makes coconut shell charcoal and charcoal powder. It does not make or sell activated carbon. This note covers charcoal vs activated carbon: where charcoal sits in the chain, which numbers belong to which product and when Kora is, or is not, the right supplier.

Two products, two jobs

Coconut shell becomes charcoal by pyrolysis: it is heated in a kiln or retort with little air until it turns into carbon-rich lumps. Kora does this in its own kilns and retorts. That charcoal can be used as fuel, or it can be taken by a processor and activated, which is a separate and demanding step done in specialised plants with steam or chemicals. The result, activated carbon, is a different product with a different market, different customers and different tests.

So the chain looks like this:

1. Shell is collected.
2. Shell is carbonised into charcoal (Kora’s step).
3. Charcoal is crushed or milled to the size the processor needs (Kora offers lump and powder).
4. The processor activates it.
5. The activated carbon is graded, packed and sold to water, gold, air or other users.

Kora sits at step 2 and, for powder, step 3.

Charcoal vs activated carbon: which numbers belong to which product

A request often fails because it asks one product for the other’s numbers. As a rough guide:

Typically asked of the charcoal feedstock	Typically asked of the activated product
Fixed carbon	Iodine number
Volatile matter	Surface area
Ash	Hardness after activation
Moisture at loading	Adsorption tests for the target use
Size range of lump or mesh of powder	Particle size grade of the finished carbon

Kora publishes fixed carbon, moisture and ash limits for lump charcoal (at least 70 %, up to 10 % and up to 5 %), and a moisture limit for powder (up to 10 %). Kora does not publish volatile matter, size spread or hardness for its charcoal. It also has nothing to say about iodine number or surface area, because it does not make the activated product. If you ask Kora for an iodine number, the honest answer is that the number does not exist for this product.

When Kora is the right supplier

Kora is a fit if you:

• operate an activation line and buy charcoal or powder as the raw material;
• trade charcoal feedstock to processors and can state what the processor needs;
• want a supplier that says plainly which data it has and which it lacks, and will provide a sample and a COA with each lot.

When Kora is not

Kora is not the supplier if you need ready-made activated carbon for water treatment, gold recovery, air filtration or any other end use. Tell us your application and we will say so directly; it saves both sides time.

Paperwork differs too

Charcoal and activated carbon are not the same item for customs. Kora’s pages print one HS code for charcoal, and activated carbon is generally listed under a different heading. For the sea route, secondary sources report that charcoal and activated carbon can also be treated differently under dangerous-goods rules. Kora’s pages do not state a classification, so confirm both customs heading and dangerous-goods treatment for your cargo with your forwarder before booking.

What to send if you are a processor

• Lump or powder, and the size or mesh range you can feed.
• Your expected monthly volume and destination port.
• The properties you need reported: fixed carbon, volatile matter, ash, hardness.
• Whether you activate with steam or chemicals, if you want to share it, since that may change what you ask for.
