The short answer: in the coir trade, "bulk" starts at one pallet of compressed blocks or bales from a domestic distributor and runs up to full 40 ft containers bought directly from a manufacturer in India or Sri Lanka. A pallet of 5 kg blocks typically carries 200 to 240 blocks and weighs around a tonne; a 40 ft high cube carries about 20 pallets and is limited by weight, not space. Compare quotes on the cost per litre of expanded, usable medium rather than per block, agree a written specification and a tested sample before ordering, and book early, because husk supply and sun-drying depend on the weather in southern India and Sri Lanka.
Key points
- Published pallet examples: 200 blocks (about 2,250 lb) per pallet from a US distributor; 220 to 240 blocks per pallet and 20 pallets per 40 ft high cube from a Sri Lankan exporter.
- The same exporter loads 25 kg bales two ways: 630 to 650 bags and 15 tonnes floor-loaded, or 440 bags on 20 pallets and 11 tonnes palletised. Pallets cost cargo.
- Monsoons from June to September and October to January slow sun-drying (Fernland, 2021), and 2025 to 2026 trade reports describe husk shortages and higher raw-material prices.
- Riococo advises ordering substrate 3 to 4 months before planting; HortGrow Solutions suggests planning up to a year ahead.
What "bulk" means in the coco coir trade
| Scale | Typical buyer | How it is sold | Source |
|---|---|---|---|
| Retail unit | Home grower | Single 650 g brick, 5 kg block or 50 L bag | Garden centre, online shop |
| Case or part-pallet | Small nursery, market garden | Cartons of bricks, 10 to 50 blocks | Domestic distributor |
| Pallet | Garden centre, greenhouse, landscaper | 200 to 240 blocks, about 1,500 bricks, or stacked bales | Distributor or importer |
| Container (LCL or FCL) | Blender, distributor, large grower | Part of a container (LCL) or a full 20 ft or 40 ft container (FCL) | Manufacturer or exporter at origin |
Biology Insights' 2026 buyer's guide describes the same ladder, with "direct importers and bulk agricultural suppliers" selling full pallets or container loads for the biggest savings.
The jump that matters is from pallet to container. At pallet scale you buy a finished product from stock and get it in days. At container scale you specify the product, wait for it to be made, pay sea freight and clear customs, and get it in weeks or months. The price per litre is lower, but you take on the specification, testing and timing work the distributor was doing for you. The paperwork side is covered in importing coco peat from India; this article covers the buying decisions that come before it.
Blocks, bales, briquettes and bags
Compressed formats dominate bulk trade because they cut freight. A 5 kg block is compressed about 5:1 and expands to roughly 2.5 cubic feet, around 70 litres, according to FibreDust's product sheet; why yields vary between suppliers is covered in the coco peat blocks guide.
| Format | Typical unit | Best for | Watch out for |
|---|---|---|---|
| 5 kg block | 30 x 30 x 12 cm, 5 kg (Sri Lankan exporter data sheet) | Blenders, greenhouses, distributors repacking into bags | Needs hydration space and equipment |
| 650 g briquette | About 20 x 10 x 5 cm (True Leaf Market) | Garden-centre retail, mail order | Highest packaging cost per litre |
| 25 kg bale | Bagged, about 32 x 46 x 72 cm (same data sheet) | Potting-mix lines with a bale breaker | Heavy to hand-move; fewer tonnes per container when palletised |
| Grow bag / open-top slab | 1 m slab, 1.7 to 3.4 kg compressed (same data sheet) | Greenhouse fruit and vegetables, hydroponics | Counted per container, not per pallet |
| Husk chip block | 30 x 30 x 17 cm, 4.5 kg (same data sheet) | Orchids, blends needing air porosity | Different expansion and water holding from pith |
| Loose 50 L bag | Expanded, ready to use | Growers without hydration space | You pay to ship water and air |
The Sri Lankan data sheet shows how grow bag counts depend on size: 7,600 to 15,000 pieces per container for slabs from 100 x 20 x 14 cm (3.2 kg) down to 100 x 15 x 10 cm (1.7 kg). Decide the format for your crop first, then ask for the loading plan. CVM's products page lists its blocks, briquettes, grow bags, open-top slabs, husk chips and custom blends.
How coir is palletised and loaded
True Leaf Market's bulk-coir page lists 200 compressed 5 kg blocks per pallet at about 2,250 lb on a 42 x 40 x 80 inch footprint, and 1,500 bricks per pallet at about 2,150 lb. The Sri Lankan exporter's data sheet lists 220 to 240 blocks per pallet, strapped and shrink-wrapped, 20 pallets per 40 ft high cube and a minimum of 23 tonnes per container. A standard EPAL Euro pallet is 1,200 x 800 mm with a safe working load of 1,500 kg (EPAL), so a tonne of blocks per pallet is within limits; ask whether the supplier uses Euro, 1,200 x 1,000 mm or 48 x 40 inch pallets, because that decides how the load fits your racking and trucks.
Two loading choices change the economics:
- Palletised or floor-loaded. The same exporter lists 25 kg bales at 630 to 650 bags and 15 tonnes per 40 ft high cube floor-loaded, against 440 bags on 20 pallets and 11 tonnes palletised. Pallets take roughly a quarter of the cargo. Floor-loading is cheaper per tonne but means manual unloading at your dock.
- Weight, not volume, sets the quantity. Compressed coir is dense, so a 40 ft high cube of 5 kg blocks reaches weight limits before it is full, which is why suppliers quote "minimum 20 tonnes" or "minimum 23 tonnes" rather than a block count. The road limit at destination is usually the binding one; check it with your forwarder.
Fumigation and phytosanitary inspection are normally done during container loading (the Sri Lankan sheet states this), so the supplier needs your destination country's plant-health requirements before the container is stuffed.
Comparing quotes: per block, per litre, per tonne
| Quote basis | Common for | Problem |
|---|---|---|
| Per block or brick | Distributors, retail-pack suppliers | Hides moisture, sand and expansion differences |
| Per tonne | Exporters, FCL quotes | A tonne of wet, sandy pith is not a tonne of dry pith |
| Per litre expanded | Blenders, grower contracts | Only comparable if the expansion method is stated |
The number that reflects what you can actually pot or fill is the cost per litre of expanded, usable medium:
cost per litre = (price per unit + freight and duty per unit) / litres yielded per unit
A worked example in illustrative price units, not market prices: supplier A quotes 1.00 per 5 kg block and the block yields 60 L in your own test; supplier B quotes 1.15 and yields 75 L. A costs 0.0167 per litre, B costs 0.0153, so the dearer block is about 8% cheaper per litre before freight, and since both ship the same weight, freight widens the gap.
Three things make the conversion honest:
- Measure the yield yourself, with your own water and method, on a sample from current production. Published figures run from about 50 to 100 litres per 5 kg block depending on how the volume is measured.
- Correct for moisture. A block pressed wet contains less coir per kilogram. Ask for moisture at the time of weighing and weigh sample blocks on arrival.
- Correct for sand and fines. Sand adds weight; very fine dust compacts. Both reduce usable volume.
For per-tonne FCL quotes, also normalise the Incoterm, pallet choice and format, otherwise you are comparing freight terms, not coir.
What to ask a supplier before ordering
Product
- Which formats and block sizes do you produce, and which are made to order?
- Is the pith washed, and with what water? Buffered or unbuffered? (CVM washes with water to reduce EC and does not buffer or add calcium nitrate.)
- What EC and pH do you report, by which extraction method, and will the method appear on every batch report?
- Particle grade and fibre or chip percentage; can you supply a sieve analysis?
- Expansion yield per kilogram, by which method, at what moisture?
- Maximum moisture at compression and maximum sand content?
Packing and loading 7. Blocks per pallet, pallet type and dimensions, strapping and wrap? 8. Floor-loaded or palletised, and the tonnage each way? 9. Labelling: batch number, production date, country of origin, our brand?
Supply 10. Minimum order for a first trial and for repeat orders? 11. Current lead time from order to loading, and how it changes in the monsoon? 12. Do you hold dried raw material in stock, or process to order? 13. Do you keep a retained sample from each batch, and will you accept third-party inspection? 14. Who handles fumigation and the phytosanitary certificate?
Exporters commonly list "1 x 40 ft HC" as the minimum for direct export orders; distributors sell by the pallet. CVM describes its export arrangements on the export page and agrees quantities per order.
Sampling and testing before the first container
A pallet from a distributor is the product you can see; a container made to order does not exist yet when you pay the deposit, so sampling carries the risk.
- Ask for a production sample, not a showroom block, with the batch report that went with it.
- Test what you will pay for: expansion volume, moisture, EC and pH by your stated method, sand by the sink test, and a visual check for fibre strands, stones, plastic and seeds.
- Grow in it. HortGrow Solutions' James Susaimuthu recommends small-scale trials before committing (HortiDaily, September 2025). A tray of seedlings shows problems a conductivity meter will not.
- Agree the pre-shipment test in the contract: supplier batch report, third-party inspection, or sealed retained samples held by both sides.
- Keep a retained sample from every delivery, labelled with the batch number, so a problem in week six of a crop can be traced to a lot.
Lead times and seasonality
Coir is a by-product of the coconut industry and is largely sun-dried, so supply follows the weather.
Monsoons slow drying. Fernland, an Australian horticultural supplier, told customers in its October 2021 price review that "the summer monsoon from June to September and the winter monsoon from October to January has a significant impact on production volumes as all product is 'sun dried' in external drying yards." Dutch Plantin's Wim Roosen made the same point in HortiDaily in 2014: monsoons in India and Ivory Coast affect production and logistics and do not always arrive on schedule. Krishna Patil of Krishna International Trade told HortiDaily in January 2026 that irregular rainfall over two years had slowed drying, that ready-to-ship stock was limited, and that prices were up to 10% higher than in recent months as a result.
Husk availability depends on the coconut crop. Tharun Kumar of M2Balu Export reported in HortiDaily (October 2026) significant increases in husk and wet cocopeat prices since the start of 2026, smaller husks yielding less usable material, and insufficient rainfall and high temperatures in growing regions. He expected the first half of 2027 to be stable for larger manufacturers holding stocks and the second half to be the bigger concern. Susaimuthu said in September 2025 that raw-material prices had tripled in a year, citing demand, poor rainfall and disease pressure. Jaime Rodríguez of Coflor told Infoagro 2025 that monsoons in Sri Lanka and India had "lasted longer than usual, which delayed harvesting," and that India's push for plantation renewal was also reducing husk supply.
Raw material needs ageing. Roosen noted that pith must reach a certain age before it performs well, which is why established producers store dried pith rather than processing husks straight into blocks. A supplier with stock can hold lead times through a wet season; one processing to order cannot.
Shipping adds weeks. Shan Halamba of Riococo put the Sri Lanka to Europe journey at 35 to 40 days in April 2025, with Red Sea diversions adding 10 to 15 days, and advised ordering 3 to 4 months before planting (HortiDaily). Fernland reported 4 to 6 week waits for containers in 2021. Kumar said in October 2026 that freight to Europe had eased by a few hundred dollars, but gave the same advice: discuss requirements early so the manufacturer can plan production.
The supply picture is not uniformly tight. Halamba said Sri Lanka ships about 16,000 containers of coco substrate a year against a potential of more than 50,000, with less than 60% of husks used, and Patil put Indian production up 5 to 8% year on year. The constraint is drying capacity, husk price and timing rather than the existence of raw material.
Quality consistency between lots
Lots vary with the husk source, how long the pith was stored, and how it was washed and dried. Roosen's 2014 article noted that having enough raw material does not guarantee supply to professional horticulture, because strict product requirements limit which processes are acceptable, and Patil said in 2026 that domestic buyers often face uneven quality while exporters face tight checks on EC, pH and moisture.
- Specify tolerances, not just targets. "EC below a stated value by a named extraction method" is a specification; "low EC" is not. The same applies to moisture, sand and expansion.
- Ask for a batch report on every lot and compare it with your retained samples.
- Expect drift between the trial container and the third. Build an arrival check into your receiving process.
- Avoid switching supplier mid-season. Two low-EC products from different mills can still behave differently under irrigation; run new material alongside the old before switching a whole crop.
Common pitfalls for first-time bulk buyers
- Buying on price per block. A cheap block with poor expansion or high moisture costs more per litre.
- Comparing EC figures measured by different methods.
- Ordering a container by volume. Coir is weight-limited; an overweight container is refused or split.
- Not deciding on pallets. Pallets cost about a quarter of the cargo but save unloading labour. Get the quote on the basis you want.
- Ordering in the wet season with a tight deadline. Book early or buy from a supplier holding stock.
- Skipping the grow trial.
- Paying the balance before documents and tests.
- Letting the trial lot set an unwritten standard. Put tolerances in the specification so the third container is held to the same numbers as the first.
If you are planning a first pallet or container of 5 kg blocks or another format, contact CVM with your crop, format and destination to work out a specification and sample.
FAQ
How many 5 kg coco coir blocks are on a pallet?
Published examples range from 200 to 240 blocks per pallet. A US distributor lists 200 blocks at about 2,250 lb, and a Sri Lankan exporter lists 220 to 240 blocks strapped and shrink-wrapped. The count depends on pallet footprint, block dimensions and stacking height, so confirm it with each supplier.
How many coco peat blocks fit in a 40 ft container?
Around 20 pallets, or about 4,400 blocks, with suppliers quoting a minimum of 20 to 23 tonnes. Compressed coir is dense, so the container reaches its weight limit before it is full, and road weight limits at the destination often cap the load below the container's rated payload.
Is it cheaper to buy coco coir palletised or floor-loaded?
Floor-loading puts more coir in the container. One exporter lists 15 tonnes of 25 kg bales floor-loaded against 11 tonnes palletised in the same 40 ft high cube. Floor-loading is cheaper per tonne but needs manual unloading at your dock, so the saving depends on your labour and equipment.
Should I compare coco coir quotes per block, per tonne or per litre?
Per litre of expanded, usable medium. Divide the delivered price per unit by the litres that unit yields in your own hydration test. Per-block and per-tonne prices hide moisture, sand and expansion differences that change the real cost of the medium you end up with.
What is the minimum order for buying coco coir direct from a manufacturer?
Exporters commonly list one 40 ft high-cube container as the minimum for direct export orders. Smaller quantities are usually bought from an importer or distributor by the pallet, or shipped as less-than-container (LCL) cargo at a higher freight cost per tonne.
When is the best time to order coco coir in bulk?
Well ahead of the wet seasons in southern India and Sri Lanka, when sun-drying slows and lead times stretch. Suppliers quoted in the trade press advise ordering three to four months before planting, and planning up to a year ahead for large or recurring volumes.
How long does a bulk coco coir order take to arrive?
Add production time to shipping time. Sea freight from Sri Lanka or India to Europe was put at 35 to 40 days in 2025, with Red Sea diversions adding 10 to 15 days. Production time depends on whether the supplier holds dried raw material or processes to order, and on the weather during drying.
How do I make sure the second container matches the first?
Write tolerances for EC, pH, moisture, sand and expansion into the specification, ask for a batch report on every lot, keep sealed retained samples from each delivery, and repeat the key tests on arrival. Some variation between husk sources and drying conditions is normal; the specification holds it within limits.
