Indonesia exports dried Eucheuma cottonii (Kappaphycus alvarezii) as sun-dried bales at moisture 35-39% and foreign matter 2-5%, packed in 50 or 100 kg polypropylene bags with a 12-month shelf life. Trade runs FOB, CIF or CNF, shipped 30-60 days after payment approves, priced USD 4-12/kg per 2026.
Indonesia and the Philippines are the two dominant sources of cottonii (locally rumput laut, katoni or sakul), the red seaweed that yields kappa karagenan. Industry sources describe Indonesia as the world’s largest producer of red seaweeds. Cottonii became cultivable here in 1974 and is grown by the longline method — plastic rope tied to lines anchored to seabed poles — across warm equatorial waters, roughly within 20 degrees of the equator, where the crop can gain about ten times its mass in 45-50 days.
What exactly ships when you order dried cottonii?
You receive raw, sun-dried Eucheuma cottonii, not processed carrageenan. The seaweed is cut, sun-dried, sorted for foreign matter, then pressed into bales wrapped in polypropylene cloth and filled into 50 kg or 100 kg bags. Dried cottonii is the feedstock that carrageenan processors, food and nutraceutical manufacturers, and private-label health brands buy before extraction.
Spinosum (Eucheuma spinosum) is a separate species that yields iota carrageenan — confirm which one your process needs before you request a quote, because gel behaviour differs.
Which grade and moisture band fits your buyer?
Documented wholesale specs vary by trader and by harvest. Lower moisture and lower impurity command higher prices because they lose less weight in transit and resist mould. The table below shows real, published grade ranges.
| Documented grade | Moisture | Impurity / foreign matter | Drying |
|---|---|---|---|
| Standard lot | 35-37% max | 3% max | sun-dried |
| Higher-impurity lot | 35-37% | 5% max | sun-dried |
| Higher-moisture lot | 37-39% | 2% max | sun-dried |
| Premium “Dried Raw Algae Grade A” | under 35% | under 2% | Grade A & B selection |
Every moisture, ash, foreign-matter, microbiological, heavy-metal or carrageenan-yield figure is only verifiable against a specific batch Certificate of Analysis. Treat any spec quoted before you hold that COA as a target, not a promise.
What does dried cottonii cost to export in 2026?
| Grade | Moisture (max) | Foreign matter | Indicative FOB (USD/kg) |
|---|---|---|---|
| Commodity / salted, higher-moisture | 37-39% | up to 5% | 4-7 |
| Standard sun-dried | 35-37% | 3% | 6-9 |
| Higher-grade, low-moisture clean | under 35% | under 2% | 9-12 |
| Cleaned / washed food-grade bulk | per COA | per COA | 25-55 |
That band is FOB indicative per 2026 and moves with harvest, moisture and grade; the final quote follows your confirmed spec and MOQ. Cleaned, washed food-grade bulk sits far above raw dried because of the extra sorting and processing. Branded Western retail sea moss is priced higher again — that is a consumer shelf price, not our FOB quote.
One caution on comparing offers: some listings quote per bag rather than per kilogram. An undated export listing showed FOB “starting at $1330/Bags” from Indonesia — a per-bag figure that shifts with volume, packaging and destination and cannot be read as a per-kilo rate. Always confirm the unit before you compare.
How do container loading and MOQ work?
A typical trial ships 1 MT so you can test the material, then contracts scale to 20-100 MT. Container capacity sets the rhythm:
- 20ft container: about 15 MT
- 40ft container: about 23 MT
- 40HC container: about 25 MT (close to 350 hundred-kilo bales)
Some exporters run multiple FCL per month, so large repeat programmes are feasible from Indonesian gateways. Stored cool, dry, sealed and out of direct sunlight, dried cottonii holds its 12-month shelf life.
Which export documents come with each shipment?
| Document | Purpose | Availability |
|---|---|---|
| Certificate of Analysis (COA) | moisture, ash, foreign matter, microbio, heavy metals, carrageenan yield per batch | Included |
| Material Safety Data Sheet (MSDS) | handling and safety | Included |
| Fumigation Certificate | pest treatment | Included |
| Phytosanitary Certificate | plant-health clearance | Included |
| Certificate of Origin (COO) | proof of Indonesian origin | Included |
| Halal certificate | faith-based market access | On request |
| HACCP / ISO 22000 | food-safety system | On request |
We supply the documents most import authorities ask for, but no honest exporter guarantees customs clearance. Import duties, testing and border inspection in your country stay yours to confirm with your broker before shipment.
Where does the seaweed come from?
Indonesia’s cottonii is farmed across Maluku, West and East Nusa Tenggara (NTB, NTT), West Lombok, North Kalimantan and South Sulawesi — Bone, Maros, Jeneponto, Takalar, Luwu and East Luwu. Surabaya and wider East Java form the main processing and export gateway; the region hosts a real, expanding domestic carrageenan-processing base, with large seaweed processors that market cottonii as a high-gel-strength kappa source. Bali works as a sourcing and logistics hub rather than a large farming zone.
Seasonality matters: monsoon rains lengthen sun-drying and push moisture up, while ice-ice disease and epiphytes can dent yield. Lock your grade and delivery window early in the rainy months.
How does an export order actually work?
- Send your spec. Message the desk your destination, target grade, moisture ceiling and monthly volume by WhatsApp or the inquiry form.
- Get an indicative quote. The desk returns a 2026 FOB band and a sample offer within 24 working hours.
- Approve the sample and COA. Confirm moisture, cleanliness and gel strength against the batch COA, then agree MOQ and Incoterm (FOB, CIF or CNF).
- Approve payment. Terms are T/T, 100% irrevocable LC at sight, or 100% advance.
- Production and QC. Drying, sorting, baling and documentation run over 30-60 days after payment approves.
- Loading and shipment. Bales load into your container and ship worldwide with the agreed documents.

Frequently Asked Questions
Can you guarantee my dried cottonii clears customs in my destination country?
No honest exporter can. We cannot guarantee customs clearance or that a batch passes your border inspection. We supply the COA, phytosanitary certificate, COO, MSDS and fumigation certificate that most authorities require, plus Halal or HACCP paperwork on request. Import rules, duties and testing stay your responsibility to confirm with your broker beforehand.
What moisture level should I specify for dried Eucheuma cottonii export?
Documented trade grades run from below 35% for premium low-moisture selections up to 37-39% for standard, higher-moisture lots, with foreign matter between 2% and 5%. Lower moisture means less weight loss and mould risk but a higher FOB price. State your target moisture and maximum impurity in writing; any figure is verifiable only against a batch COA.
How is dried cottonii packed and loaded for shipping?
Seaweed is pressed into bales wrapped in polypropylene cloth, then filled into 50 kg or 100 kg bags. A 20ft container holds roughly 15 MT, a 40ft about 23 MT, and a 40HC near 25 MT, which is close to 350 hundred-kilo bales. Cool, dry, sealed storage away from sunlight preserves the 12-month shelf life.
What is the minimum order to start a dried cottonii export contract?
A typical trial ships 1 MT so you can test moisture, gel strength and cleanliness before committing. Contract volumes then rise to 20-100 MT, since a single container carries roughly 20-25 MT. Send your destination, grade and monthly demand, and the Bali Premium Trip desk returns an indicative FOB quote within 24 working hours.
