Indonesian coco peat and coir
Coco peat is the pith left when coconut husk is processed for fibre, compressed into blocks and used as a growing substrate. Indonesia has the husk supply to produce it at scale. The property that decides whether a consignment is usable is salt content, and that is set by how thoroughly the material was washed.
How it leaves the country.
- Blocks and bricks
- Compressed to a fraction of their expanded volume, which is what makes the material economic to ship. Sold by block weight and expansion ratio.
- Grow bags and slabs
- Pressed to a finished shape for horticultural production lines, usually wrapped and ready to plant into.
- Coir fibre
- The long fibre separated from the pith, used for mats, ropes, brushes and erosion control. A separate trade with separate buyers.
- Chips and husk chunks
- Coarser fractions blended into a substrate to open its structure and hold air. Ordered as a proportion of the mix.
How it is graded.
Growing media is bought on measured properties. The specification below is what separates a usable consignment from an expensive block of salt.
- Electrical conductivity
- The measure of soluble salts. Coconut husk carries sodium and potassium naturally, and washing is what removes them. Name your maximum in the contract.
- Washed, buffered and unwashed
- Three different products at three prices. Buffered material has been treated with a calcium solution to displace sodium held on the exchange sites, which plain washing does not reach.
- Particle size and fibre content
- The pith to fibre ratio decides water holding and air porosity. A substrate for propagation and one for long-season fruit are not the same blend.
- Expansion ratio
- How many litres a block yields when wetted. It is what you are actually buying, so it belongs in the contract alongside the block weight.
- Moisture at loading
- You pay freight on water. A block loaded wet costs more per usable litre and arrives heavier than the packing list says it should.
How it is packed.
- Palletised blocks
- Stacked and strapped, loaded to fill the container by volume. Compression is the entire economics of the product.
- Wrapped for moisture
- Blocks take up humidity in transit and can arrive soft and mouldy on a long tropical routing. Wrapping and stowage belong in the order.
- Fumigation and pallets
- Wooden pallets under the load need the heat treatment mark, and that is checked at arrival independently of the cargo itself.1
Where it grows.
North Sulawesi
Sulawesi
A long-established coconut region with husk available in volume alongside the copra and oil trade.
Riau
Sumatra
Extensive coastal coconut planting on the east coast, feeding processors close to the ports.
Central Java
Java
Processing capacity serving both the fibre trade and the substrate trade, with good container access.
Choosing between this and something else.
Documentation, where applicable.
- Phytosanitary certificate
- A plant product going into horticulture, so plant health is the first question the destination asks.2
- Certificate of analysis
- Electrical conductivity, pH, moisture and particle distribution on the shipped lot. The document this product is bought on.
- ISPM 15 mark
- On the pallets under the cargo. Checked separately from the goods and a common reason for a hold.1
- Certificate of origin
- Which form applies depends on the destination and the preference scheme in force with Indonesia.
Questions buyers ask.
Why does salt content matter so much?
Because the substrate sits against the roots for a whole season. Coconut husk holds sodium and potassium naturally, and material that was rinsed quickly rather than washed properly will release them into the root zone. The damage shows up weeks after planting, by which time the consignment is long since paid for.
What is buffering, and do I need it?
Washing removes salts held in the water. Buffering treats the material with a calcium solution to displace sodium held on the exchange sites, which washing alone leaves behind. Growers running long crops on high-value production generally specify buffered material. For short propagation cycles, washed is often enough.
How do I compare prices between suppliers?
Per expanded litre, with the EC specification attached. A price per block means nothing until you know the expansion ratio and the salt level, and those two are exactly what varies between an inexpensive offer and a usable one.
What does your service cost?
Five per cent of the order value, paid by you and never by the factory. A factory audit starts at $250 depending on location. We work with orders from $10,000 per shipment.
