Why buyers source mustard seeds from India
India is the second largest mustard producer in the world, with the crop concentrated in Rajasthan, Haryana, Madhya Pradesh and Uttar Pradesh. It is a rabi crop, sown after the monsoon and harvested from February, which places Indian supply in a different window from Canadian and European rapeseed.
What distinguishes Indian mustard seeds commercially is pungency. The Indian brassica types carry high allyl isothiocyanate, which is the compound responsible for the sharp bite that condiment makers and South Asian food manufacturers specifically want. Milder canola-type rapeseed cannot substitute for it.
Demand has broadened beyond the diaspora trade. Clean-label condiment producers, pickle manufacturers and spice blenders now buy Indian material on specification, and whole seed moves into bakery and snack topping applications as well.
Seed and oil are regulated differently at destination. Seed moves almost everywhere; edible mustard oil does not. Establish the position for your market before you contract the oil.
What India offers
Black and brown mustard seed
The volume export grade and the pungent one. Grown across the northern rabi belt, sold on oil content for crushing and on purity and isothiocyanate for condiment use.
Yellow mustard seed
Milder, lower in oil, larger seeded. It goes into table mustard, pickling brines and spice mixes, and buyers usually specify seed size alongside purity.
Kachi ghani mustard oil
Cold-pressed, unrefined, pungent and dark. A premium retail product in South Asia and its diaspora markets, shipped in retail packs, drums or flexitanks depending on volume.
Mustard oil cake
The expelled residue, contracted on protein and residual oil, used as cattle feed and organic fertiliser. It is a separate market with its own price cycle.
Reference specifications for mustard seed
The table above is the working baseline for mustard seed. Two clauses carry most of the commercial weight, and only one of them is oil content.
Free fatty acid is where value leaks on any oilseed. It rises with moisture, heat and storage time, so contract a ceiling and require a pre-shipment analysis rather than accepting a harvest-time certificate.
Purity and admixture on mustard seed need numeric limits. Mustard is a small seed and is commonly grown in mixed fields, so other brassica seed in the lot is a real risk rather than a theoretical one.
Condiment buyers should specify allyl isothiocyanate content explicitly. It is the property being purchased and it varies by seed type, region and season.
Mustard seed food safety and regulatory position
Pesticide residues follow the destination’s maximum residue levels. European buyers should name testing against the current EU list; most other markets accept Codex.
Erucic acid is the parameter that governs whether mustard oil may be sold for edible use. Indian mustard is naturally high in it, and several jurisdictions restrict edible mustard oil for that reason. This does not affect the seed trade, but it decides the oil trade entirely.
For condiment and food-grade seed, ask whether the lot has been steam sterilised and at what parameters, and require a microbiological certificate. Chemical sterilisation leaves residues that European buyers now test for routinely.
Documentation for a mustard seed shipment
- Commercial invoice and packing list with lot numbers matching the bags
- Bill of lading or air waybill
- Certificate of origin, preferential where a trade agreement applies
- Phytosanitary certificate with the destination’s additional declarations
- Fumigation certificate stating fumigant, dose, duration and temperature
- Certificate of analysis covering oil content, FFA, moisture, purity and admixture
- Pesticide residue report from an accredited laboratory
- Health certificate or free sale certificate for oil shipments, where required
- Non-GMO declaration, which Indian mustard supports by origin
Exports are registered through APEDA, and edible oil production is licensed by the Food Safety and Standards Authority of India. Ask for both numbers where oil is involved.
Packing and shipping mustard seed
Mustard seed ships in 25 kg or 50 kg PP woven bags, with food-grade liners on condiment lots and one-tonne bulk bags for crushing programmes. A 20 ft container loads about 25 to 27 MT and is weight limited.
Oil moves in retail packs and jerry cans for consumer markets, in 200 litre drums for industrial buyers, and in flexitanks for full-container volumes. Flexitank shipment requires a nitrogen blanket or a short transit to protect the flavour on cold-pressed oil.
Specify container liners on food-grade seed. They isolate the cargo from residues of previous loads, which is a question your auditor will eventually ask.
Ports and routes for mustard seed cargo
Most Indian mustard seeds move through Mundra and Kandla, close to the Rajasthan and Haryana growing belt, with Nhava Sheva serving some condiment and retail oil volumes. Indicative transit runs eight to twelve days to Jebel Ali, eighteen to twenty-four days to Southeast Asia and twenty-two to thirty days to North European base ports.
Build the fumigation window into the schedule, and remember that oil shipments have their own tank cleanliness certification that must be arranged before loading rather than after.
Season and availability of Indian mustard seed
Mustard is a rabi crop. Sowing runs through October and November, harvest begins in late February, and peak mandi arrivals fall in March and April. That is the freshest and usually the best-priced window.
Carryover material is available through the second half of the year, but oil content drifts and free fatty acid rises. A buyer contracting in September should ask for a current analysis rather than the harvest certificate.
How mustard seed is priced and contracted
The price of mustard seed is built from the mandi seed price, cleaning and grading cost, bagging and inland freight, and the exporter’s margin, with ocean freight and insurance added on CIF terms. The domestic edible oil complex sets a floor: when domestic crush margins are strong, exportable seed surplus shrinks.
Most contracts run FOB Mundra or Kandla with CIF on request, against an irrevocable letter of credit at sight. Include a price adjustment per point of oil content so a marginal analysis settles itself.
How to qualify a mustard seed supplier
- Ask for the IEC, APEDA registration and FSSAI licence numbers and verify them independently.
- Ask which facility will clean, sort or sterilise the lot and whether it holds ISO 22000 or HACCP certification.
- Ask for a pre-shipment sample from the actual lot with oil content, FFA and purity reported.
- For oil, ask to see the tank or flexitank cleaning certificate and the packing line certification.
- Ask for two references in your own market who have taken material in the last twelve months.
RNG Agro Exports holds FSSAI, APEDA and ISO 22000 certification and contracts directly with processors in the northern rabi belt. Our Indian oilseeds guide covers the wider basket if you are buying more than one seed.
Common mistakes importers make with mustard seed
The first is contracting seed type loosely. Black, brown and yellow mustard are three products, and substituting one for another changes the finished condiment.
The second is buying oil without checking import permissibility. Erucic acid restrictions have caught more than one first-time buyer at the border.
The third is ignoring free fatty acid at discharge. Contract it at both ends and the incentive to ship dry seed sits with the right party.
The fourth is fixing a full year at harvest. Mustard prices move with the rabi crop and with domestic oil policy, and both are worth splitting exposure against.
Frequently asked questions about mustard seed
- What is the difference between black, brown and yellow mustard?
- Black and brown Indian mustard carry high allyl isothiocyanate and deliver the sharp pungency used in Indian cooking and in strong condiments. Yellow mustard is milder, lower in oil, and is used for table mustard, spice blends and pickling. They are different products and should be contracted separately.
- What oil content should I expect from Indian mustard seeds?
- Rabi mustard from Rajasthan and Haryana typically runs 38 to 42 per cent oil on a dry basis. Yellow mustard sits lower at 34 to 38 per cent. Always specify the basis, because a figure quoted as received moves with moisture.
- Can mustard oil be imported into any market?
- No. Several destinations restrict mustard oil for edible use because of its erucic acid content, and permit it only for external or industrial use. Confirm the position with your own food safety authority before contracting oil rather than seed.
- What is kachi ghani mustard oil?
- It is cold-pressed oil expelled at low temperature without refining, which preserves the pungency and the natural colour. It is a premium product in South Asian and diaspora markets and carries a shorter shelf life than refined oil.
- How is mustard cake used?
- Mustard oil cake is the residue after expelling and is used as cattle feed and as an organic fertiliser. It is contracted on protein and oil residue rather than on pungency, and it is a separate trade from the seed itself.
- Seed type is the first decision: black or brown Indian mustard is the pungent condiment and oil seed, yellow mustard is milder and moves into table condiments and spice blends.
- Oil content of 38 to 42 per cent is normal for Indian rabi mustard. Specify it on a dry basis and pair it with a free fatty acid ceiling.
- Pungency comes from allyl isothiocyanate released when the seed is crushed. Condiment buyers should specify it; crushers usually do not need to.
- Cold-pressed kachi ghani oil is a distinct product with its own market and its own regulatory position in several destinations. Confirm import permissibility before contracting oil rather than seed.
- A 20 ft container loads roughly 25 to 27 MT of seed in 50 kg PP bags; oil moves in flexitanks, drums or IBC totes depending on volume.

Buyers who contract mustard on oil content alone and discover the pungency is wrong have bought the correct commodity and the wrong product. Seed type and isothiocyanate content are what a condiment plant is actually paying for, and both belong in the specification.
