**Indonesia is one of the world’s largest sources of red seaweed, supplying dried Eucheuma cottonii (the primary kappa-carrageenan raw material) and Eucheuma spinosum (iota carrageenan) for wholesale and export. Raw dried grades run FOB USD 4-12/kg by moisture and cleanliness; cleaned food-grade bulk sits at USD 25-55/kg. Minimum orders start at a 1 MT trial.**
If you are sourcing red seaweed but have not locked a species or grade yet, this page is the map. Carrageenan processors, food and nutraceutical manufacturers, and private-label health brands all buy from the same Indonesian farm base — they just want different grades, moisture levels and paperwork. Below are the forms, the price bands, and the steps to a quote from the Bali Premium Trip desk.
What red seaweed does Indonesia actually supply?
Two commercial red seaweeds dominate the Indonesian trade. Eucheuma cottonii — also catalogued as Kappaphycus alvarezii, and known locally as cottonii, katoni, sacul or sakul — is the leading source of kappa carrageenan, prized for firm gel strength. Eucheuma spinosum yields iota carrageenan, which gels softer and more elastic. A carrageenan-industry source describes Indonesia as “the world’s largest producer of red seaweeds (Eucheuma cottonii).”
The species grows naturally within roughly 20 degrees of latitude either side of the equator across the Indo-Pacific, concentrated in Southeast Asia, and can reach about ten times its mass in 45-50 days in warm Indonesian waters. Cottonii became cultivable in Indonesia in 1974 and is farmed by the longline method — plastic rope tied to lines anchored to seabed poles.
Production is spread across Maluku, West Nusa Tenggara (NTB), East Nusa Tenggara (NTT), South Sulawesi (Bone, Maros, Jeneponto, Takalar, Luwu, East Luwu), West Lombok and North Kalimantan. Surabaya and East Java form the main processing and export gateway — some Indonesian processors around Surabaya and East Java produce food-grade carrageenan from cottonii and spinosum. Bali works as a sourcing and logistics hub rather than a documented large production zone.
Which red seaweed grade and form fits your use?
Buyers usually fall into two camps: those extracting carrageenan and those making whole-seaweed or gel health products. This table matches species and form to typical intent.
| Species | Local name | Carrageenan type | Typical buyer / use | Common form |
|---|---|---|---|---|
| Eucheuma cottonii (Kappaphycus alvarezii) | cottonii / katoni / sacul | Kappa (firm gel) | Carrageenan processors, food, nutraceutical, health brands | Raw dried bales; cleaned food-grade |
| Eucheuma spinosum | spinosum | Iota (soft, elastic gel) | Carrageenan processors, dairy/specialty gels | Raw dried bales |
| Gracilaria (context only) | rumput laut agar | Agar (not carrageenan) | Agar producers | Raw dried |
For most first orders, the practical split is simpler: commodity/salted raw dried for carrageenan factories that will wash and refine anyway, versus cleaned, low-moisture food-grade material for buyers who need lower foreign matter going in.
What does Indonesian red seaweed cost wholesale?
Use this as your anchor. FOB indikatif per 2026, moves with harvest, moisture and grade; final quote confirmed on your spec and MOQ.
| Grade / form | Species | Typical moisture (indicative) | FOB band (USD/kg) | Typical MOQ |
|---|---|---|---|---|
| Commodity / salted raw dried | Cottonii | ~37-39% (higher) | 4-7 | 1 MT trial |
| Standard raw dried | Cottonii | ~35-37% | 6-9 | 5-20 MT |
| Premium low-moisture, cleaned | Cottonii (Grade A) | under 35% | 9-12 | 20-100 MT |
| Cleaned / washed food-grade bulk | Cottonii | food-grade, cleaned | 25-55 | on spec |
| Raw dried spinosum (iota) | Spinosum | by grade | quoted on spec / COA | 1 MT trial |
Two honest notes. The moisture ranges above are indicative grade descriptions drawn from published trader specs (some list moisture 35-37% with 3% foreign matter max; others 37-39% with 2% impurity; premium Grade A under 35%) — they are not a guarantee for your batch. Any moisture, ash, foreign-matter, microbiological, heavy-metal or carrageenan-yield figure is only claimable when it comes from your batch Certificate of Analysis. Branded Western retail sea moss sells far higher; that is not our FOB quote.
How does a red seaweed wholesale order work?
A clean sourcing run moves through six steps:
- Share your spec and volume. Tell us the species (cottonii or spinosum), target grade and moisture, whether it is food-grade or carrageenan-industrial, destination port and MOQ — over WhatsApp or email.
- Get an indicative quote within 24 working hours. We return an FOB/CIF/CNF band tied to current harvest, moisture and grade, not a made-up single number.
- Sample and COA first. Request a batch sample with its COA (moisture, ash, foreign matter, carrageenan yield) before you commit to a contract.
- Contract and terms. Trial at 1 MT, scaling to 20-100 MT contracts. Payment by T/T, 100% irrevocable LC at sight, or 100% advance; terms FOB/CIF/CNF.
- Documentation and loading. COA, MSDS, fumigation certificate, phytosanitary certificate and Certificate of Origin (COO); Halal and HACCP/ISO 22000 supplied on request. Material is baled in polypropylene cloth, 50 kg or 100 kg bags — roughly 15 MT per 20ft, 23 MT per 40ft, 25 MT per 40HC.
- Ship and follow up. Delivery is typically 30-60 days after payment is approved, shipped worldwide. Sealed, cool and dry, dried seaweed holds about a 12-month shelf life.
What paperwork and specs come with a shipment?
Serious buyers ask for a full document set, and you should. Standard export papers are the COA, MSDS, fumigation certificate, phytosanitary certificate and COO. Halal and HACCP/ISO 22000 are available on request rather than by default — confirm early if your market requires them. Seasonality is real: monsoon and rainy periods lengthen sun-drying and lift moisture, and farms manage risks like ice-ice disease and epiphytes, so both price and available grade shift through the year.
One caution worth stating plainly: red seaweed and sea moss are foods and ingredients, not medicine, so we make no disease-cure claims. Indicative prices are not a contract, and no supplier can guarantee customs clearance in your country.

Frequently Asked Questions
What red seaweed species can I buy wholesale from Indonesia?
Mainly two: Eucheuma cottonii (Kappaphycus alvarezii), the leading kappa-carrageenan source with firm gel strength, and Eucheuma spinosum, which yields softer iota carrageenan. Both ship as dried raw bales, and cottonii is also offered cleaned as food-grade bulk. Gracilaria, an agar seaweed, is a separate product line entirely.
Is Eucheuma cottonii a sea moss or a red seaweed?
It is a red seaweed, botanically Kappaphycus alvarezii, marketed internationally as a type of sea moss. In Indonesia it is called cottonii, katoni, sacul or sakul. It is the primary raw material for kappa carrageenan, so it serves both the whole-seaweed health market and the industrial carrageenan trade from the same crop.
Why is Indonesia a leading source of red seaweed?
Warm equatorial waters, wide farming areas across Sulawesi, NTT, NTB and beyond, and fast growth — cottonii can multiply about tenfold in 45-50 days — make Indonesia one of the world’s largest red-seaweed producers. A carrageenan-industry source names it “the world’s largest producer of red seaweeds,” farmed by longline since cottonii became cultivable there in 1974.
What is the minimum order for red seaweed wholesale from Indonesia?
A typical entry point is a 1 MT trial order, scaling to 20-100 MT contracts as trust and specs are confirmed. A container holds roughly 15 MT (20ft), 23 MT (40ft) or 25 MT (40HC). Payment is by T/T, irrevocable LC at sight, or advance, with delivery usually 30-60 days after payment approval.
What documents come with an Indonesian red seaweed shipment?
Standard export papers are the Certificate of Analysis (COA), MSDS, fumigation certificate, phytosanitary certificate and Certificate of Origin (COO). Halal and HACCP/ISO 22000 are supplied on request. Treat any moisture, ash, foreign-matter or carrageenan-yield figure as valid only when it appears on the specific batch COA for your shipment.
