Psyllium is one of the few agricultural commodities where a single Indian town sets the world reference price. Unjha in north Gujarat is the physical centre of the global isabgol trade, and India supplies the overwhelming majority of world demand for psyllium husk and seed. The crop is grown across north Gujarat and western Rajasthan as a rabi crop, sown after the monsoon and harvested in March and April, with arrivals concentrating in the mandis from March through May.

That concentration matters commercially. Unlike sesame or pulses, where a buyer can pivot to an alternative origin, psyllium has no meaningful substitute supply base. Price movements are therefore driven almost entirely by Indian acreage and rainfall, and a buyer with an annual programme is better served by forward contracting around the March–May arrival window than by spot purchasing through the year.

Product forms and what each is used for

Psyllium husk (isabgol)

The intact outer seed coat, mechanically separated from the seed. Sold on purity grade, which describes the percentage of pure husk after separation. This is the flake form supplied to supplement packers, bulk-laxative manufacturers and fibre brands.

Psyllium husk powder

Milled husk, specified by mesh. Coarser 40–60 mesh keeps visible texture and suits gluten-free baking and high-fibre cereals. Finer 80, 100 and 200 mesh grades flow properly in capsule filling equipment and dissolve better in drink mixes. Milling adds cost but also adds value, and the mesh should be chosen against the dosing equipment, not against a general preference for “fine”.

Psyllium seed (Plantago ovata)

The whole seed, sold for crushing, further processing or direct use. A thinner market than husk and priced accordingly.

Organic psyllium

Available under NOP and EU organic certification. Organic material commands a substantial premium, requires segregated handling through the supply chain, and needs a longer sourcing window. Insist on lot-level transaction certificates rather than a scope certificate alone.

Purity grades and reference specifications

Swell volume is the parameter that actually reflects performance. It measures how much volume a gram of husk occupies after hydration, and it correlates directly with mucilage content. A buyer who specifies only “99% psyllium” without a swell volume floor has not specified the product.

These are typical commercial ranges, not a single international standard. Write the contract against your own specification sheet, name the swell volume floor and the sterilisation method explicitly, and approve the pre-shipment sample against that sheet rather than against a description such as “export quality isabgol”.

Sterilisation: the decision that determines market access

Psyllium husk is a low-moisture agricultural product handled through open-air processing, which makes microbiological control the central technical issue in the trade. Historically much export material was sterilised with ethylene oxide. For any consignment destined for the European Union that is now a contract-breaking choice.

Ethylene oxide is not approved for use on food in the EU. The residue limit, expressed as the sum of ethylene oxide and 2-chloroethanol, is 0.05 mg/kg under Regulation (EC) No 396/2005 — effectively the limit of quantification. Detections trigger RASFF notifications and product recalls that reach the retail shelf, and a supplement brand that has to withdraw stock will not return to the supplier who caused it.

Steam sterilisation is the answer for EU-bound and most other regulated markets. It is slower and more expensive, and it can reduce swell volume if the process is poorly controlled, which is precisely why the post-sterilisation swell volume belongs on the certificate of analysis rather than the pre-treatment figure.

Regulatory position by market

United States

The US is by a wide margin the largest destination for Indian psyllium, and it is the market with the clearest regulatory anchor. FDA has authorised a health claim linking soluble fibre from psyllium seed husk to reduced risk of coronary heart disease, codified at 21 CFR 101.81. Two operative details matter to a buyer designing a product:

• The claim specifies a daily intake of 7 g or more of soluble fibre from psyllium seed husk, and the food must contain at least 1.7 g of soluble fibre per reference amount customarily consumed.
• Labelling of foods containing psyllium husk must be consistent with 21 CFR 101.17(f), the warning provision covering adequate fluid intake.

Soluble fibre content for this purpose is determined using a modification of AOAC method 991.43. Importers must also operate a Foreign Supplier Verification Program, which means the supplier’s food-safety documentation becomes part of the importer’s own regulatory file. For material entering as a dietary supplement ingredient, cGMP expectations under 21 CFR 111 apply downstream.

European Union

Two points are routinely misunderstood. First, the FDA health claim does not transfer. Under Regulation (EC) No 1924/2006 only claims entered on the EU Register may be used, and the US 7 g/day wording cannot be carried across to an EU label — verify the current Register entry before artwork is signed off. Second, ispaghula husk has a European Pharmacopoeia monograph and is long established in the EU as a bulk-forming laxative, which means the same physical material can move as a food ingredient or as a herbal medicinal substance depending on presentation and claim. That distinction determines which regulator you answer to, and it should be settled before the first order rather than after.

Germany

Germany is the strongest European market for Indian psyllium and the most demanding on documentation. German importers and contract packers routinely require an IFS or BRCGS certified supply site, a pesticide screen run against their own residue list rather than a generic panel, documented steam sterilisation with validation data, and traceability to the lot. Flohsamenschalen are also sold in pharmacy channels where pharmacopoeial specification applies, so grade and channel should be matched before quoting.

France, Italy and Spain

Food supplements in these markets operate under national notification regimes, and the botanical is well established in all three. Practically, buyers expect a pharmacopoeia-referenced specification, heavy metal results against EU limits, and a clean pesticide and ethylene oxide profile. Italian and Spanish buyers frequently source both retail-pack and bulk-blend material from the same lot, so lot-to-lot swell volume consistency carries more weight than a single strong COA.

Japan and South Korea

Japan applies the Food Sanitation Act with pesticide residues governed by its positive list, and Japanese buyers typically require a residue panel matched to their internal list. In Korea, imported material is inspected under the food safety regime administered by the Ministry of Food and Drug Safety; psyllium husk is well known in the Korean supplement market and buyers there apply tight microbiological limits alongside the residue panel.

Testing and documentation

• Third-party certificate of analysis from an accredited laboratory such as SGS or Intertek, stating purity, swell volume, moisture, ash and acid insoluble ash
• Microbiological report: total plate count, yeast and mould, E. coli, Salmonella in 25 g
• Sterilisation record naming the method, with validation data for steam treatment
• Pesticide residue report, including ethylene oxide and 2-chloroethanol for EU-bound cargo
• Heavy metals report, against USP <232>/<233> where pharmacopoeial grade is contracted
• Allergen and GMO statements, and a nutritional dossier where the buyer is building a label
• Phytosanitary certificate and certificate of origin
• Organic transaction certificate at lot level where organic is contracted
• Commercial invoice, packing list and bill of lading, declaring ITC-HS 12119032

Packing and container economics

This is where psyllium differs from every other commodity in an agro catalogue, and where inexperienced buyers get their landed cost badly wrong. Psyllium husk is extremely light. A container fills by volume long before it approaches its weight limit, so freight per tonne is several times that of a dense commodity.

Model your landed cost per kilogram of delivered fibre, not per container. Compressed baling and a switch from 20 ft to 40 ft high cube usually recover more margin on a psyllium programme than negotiating the FOB price does.

Load ports and transit

Mundra and Kandla are closest to the Unjha processing belt and handle most psyllium volume, with Nhava Sheva as an alternate. Indicative transit times from Mundra, subject to service and transhipment:

How to qualify an Indian psyllium supplier

1. Verify the Importer Exporter Code issued by DGFT and the APEDA registration-cum-membership certificate.
2. Confirm the food-safety certification is current by checking the certificate number in the certification body’s register, not by accepting a PDF.
3. Establish whether the counterparty processes or only trades. Psyllium requires milling, sieving and sterilisation capacity; ask which of those steps happen in-house.
4. Request a 500 g pre-shipment sample against your own specification and test swell volume and microbiology independently at your end.
5. Ask for a redacted certificate of analysis from a recent shipment into your specific market, and check that the sterilisation method is named on it.
6. Start with a trial container and confirm lot-to-lot swell volume consistency before committing to a term contract.
7. Agree inspection terms in writing: who appoints the surveyor, where title and risk pass, and the tolerance before rejection.

Frequently asked questions

What is the difference between 95% and 99% psyllium husk?

The figure is husk purity after mechanical separation. 95% is the standard food and supplement grade; 99% is sieved further, carries a higher swell volume, and is specified for pharmaceutical and regulated supplement use. Yield falls as purity rises, which is why the higher grade costs more.

Why does a container hold so few tonnes of psyllium?

Bulk density is very low, so the container fills by volume rather than weight. Roughly 8 to 9 MT of husk in a 20-foot container against 18 to 19 MT for a dense commodity. Build that into your landed cost from the start.

Steam or ethylene oxide sterilisation?

Steam for anything EU-bound. Ethylene oxide is not approved for food use in the EU and residues are limited to 0.05 mg/kg as the sum of ethylene oxide and 2-chloroethanol under Regulation (EC) No 396/2005.

What is the HS code?

ITC-HS 12119032 for Indian export declarations; HS 1211.90 at six digits internationally.

Is isabgol the same as psyllium husk?

Yes. Isabgol is the Hindi and Gujarati name, ispaghula husk is the pharmacopoeial name, and psyllium husk is the common trade name. All refer to the seed coat of Plantago ovata.

What is the minimum order quantity?

Trial orders from 1 MT for new buyers, then full container loads from Mundra, Nhava Sheva or Pipavav.
