Indonesian coir fibre
Coir is the fibre extracted from coconut husk, separated from the pith that becomes growing substrate. It is graded by length and by whether it was retted, and it goes to matting, rope, erosion control, brushes and mattress manufacture rather than to horticulture.
How it leaves the country.
- Bristle fibre
- The long stiff fibre, combed out and used for brushes and brooms. The highest grade by length and the smallest volume.
- Mattress fibre
- Shorter fibre, the volume product, used in mattresses, upholstery and as a raw material for curled fibre.
- Curled fibre and rope
- Twisted and cured into curled fibre or spun into rope. It moves value to Indonesia and changes the packing entirely.
- Geotextile and mats
- Woven or needle-punched into erosion control blankets and mats. A growing trade with civil engineering buyers rather than manufacturers.
How it is graded.
There is no international standard. Grading is a trade convention around length, stiffness and cleanliness, and the measurable properties matter more than the grade name.
- Length decides the grade
- Long stiff fibre for brushes, shorter for mattresses. A specification names a length range rather than a grade word, because the words differ between exporters.
- Retted or unretted
- Retting in water softens the husk and produces a softer, paler fibre. Unretted mechanical extraction is faster and coarser. Two products at two prices.
- Pith and dust content
- Fibre carrying residual pith is heavier and dirtier, and you paid freight on it. It is the property that separates a clean supplier from a cheap one.
- Moisture
- Baled damp, coir moulds and heats. Bale moisture is a specification point and a safety one on a long voyage.
- Salt
- Where husks were soaked in brackish or sea water, salt remains. It matters for anything going into a mattress or against soil.
How it is packed.
- Compressed bales
- Machine baled and strapped. Compression is the whole shipping economics, and bale density belongs in the contract.
- Volume rather than weight
- Even baled, coir fills a container long before it reaches the weight limit. Plan in cubic metres.
- Heating in transit
- Damp baled natural fibre generates heat and, in bad cases, can ignite. Moisture control is a safety question rather than a quality one.
- Plant health
- A plant product, so destinations apply their own requirements and treatment is commonly needed.1
Where it grows.
North Sulawesi
Sulawesi
Long-established coconut processing with husk available in volume alongside the copra trade.
Riau
Sumatra
Extensive coastal coconut on the east coast, feeding fibre and pith processors near the ports.
Central Java
Java
Processing capacity serving both the fibre and substrate trades, with good container access.
Choosing between this and something else.
Documentation, where applicable.
- Phytosanitary certificate
- A plant product, issued against the destination's plant health requirements.1
- Fumigation certificate
- Commonly required for baled natural fibre, and the treatment record travels with the goods.
- Certificate of analysis
- Moisture, pith content and, where it matters, salt on the shipped lot.
- Certificate of origin
- Which form applies depends on the destination and the preference scheme in force with Indonesia.
Questions buyers ask.
How is this different from coco peat?
Same husk, different fraction. Coir is the fibre and coco peat is the pith between the fibres. They are separated in the same operation and they go to completely different industries, horticulture for one and manufacturing for the other.
Why does bale moisture matter so much?
Because damp baled natural fibre heats, and in poor conditions that becomes a fire risk as well as a mould problem. It is one of the few specification points on this site that is a safety question rather than a quality one.
Is Indonesian coir different from Sri Lankan or Indian?
India and Sri Lanka have older and more developed coir industries with deeper grading conventions. Indonesia has the husk volume and is competitive on mattress fibre and on the substrate side. For fine bristle grades the traditional origins are usually the stronger answer.
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.
