About Our Mustard Seeds
Mustard is one of the world’s oldest cultivated crops, with references dating back over 3,000 years in ancient Indian, Greek and Roman texts. In Indian cooking, black and brown mustard seeds are a fundamental tempering spice — tossed into hot oil at the start of cooking to release their characteristic nutty, pungent aroma. In Western cuisine and condiment manufacturing, yellow mustard seeds form the base of everything from classic American yellow mustard to complex French Dijon and whole-grain mustards.
At UnitedSpices, we source our mustard seeds from the key growing regions of India — Rajasthan, Madhya Pradesh, Uttar Pradesh and West Bengal — where optimal agro-climatic conditions yield seeds with high oil content, uniform size and characteristic pungency. Each lot is machine cleaned, gravity sorted and screened for foreign matter before being packed in moisture-barrier materials, the same estate-to-shipment standards that govern our cumin seeds and garam masala exports.

We export three primary mustard seed varieties, each suited to different industrial applications. Black mustard (Brassica nigra) is the most pungent and preferred in South Indian cuisine. Brown mustard (Brassica juncea) is the global standard for Dijon-style mustard and cold-pressed oil. Yellow/White mustard (Brassica hirta) is the mildest and widely used in Western condiments, pickling and emulsification.

Why Glucosinolate Content Defines Mustard Seed Pungency
Mustard’s signature bite comes from glucosinolates — sinigrin in black and brown seeds, sinalbin in yellow seeds — which convert to pungent isothiocyanates when the seed is crushed and mixed with water, via the enzyme myrosinase. Our seeds are tested for glucosinolate integrity to guarantee consistent pungency on crushing.

Our Quality Commitment
Mustard seed quality is determined by three primary parameters: oil content, purity and microbiological safety. At UnitedSpices, every incoming lot is sampled and tested for oil content using the Soxhlet extraction method, moisture content, foreign matter and admixture levels before being approved for processing. Only lots meeting our minimum purity threshold of 99% proceed to the cleaning line.
Our multi-stage cleaning process uses aspiration channels, vibratory screens, gravity separators and colour-sorting optical machines to achieve outstanding seed purity — removing not just stones and dust, but also discoloured or shrivelled seeds that reduce quality. For export lots bound for allergen-sensitive markets, we provide detailed allergen statements noting mustard’s classification as one of the 14 major EU food allergens.
For food manufacturers and oil mill buyers, we provide full batch-level origin and grade declarations on the Certificate of Analysis for supply chain traceability, alongside custom grading and sieve-size services matched to specific industrial requirements.

Mustard Seeds Export — Frequently Asked Questions
Common questions from buyers sourcing mustard seeds from India.
What are mustard seeds and what varieties do you supply?
Mustard seeds are the small round seeds of plants in the Brassica family, used whole for tempering, ground into powder, or pressed for oil. We supply all three commercial varieties: Black (Brassica nigra), Brown (Brassica juncea) and Yellow/White (Brassica hirta), each with distinct pungency and industrial use.
What is the difference between black, brown and yellow mustard seeds?
Black mustard is the smallest and most pungent, used mainly in South Indian and Bengali tempering. Brown mustard (Rai) has medium-high pungency and the highest oil content, making it the standard for Dijon-style mustard and cold-pressed mustard oil. Yellow/White mustard is the mildest and largest seed, used in American yellow mustard, whole-grain condiments and emulsifiers.
What is the oil content of your mustard seeds?
Oil content varies by variety: 28-32% for Black mustard, 32-40% for Brown mustard, and 28-34% for Yellow/White mustard, all verified by Soxhlet extraction testing on every export lot.
Are your mustard seeds suitable for cold-pressed mustard oil production?
Yes. Our Brown mustard (Brassica juncea) seeds, with 32-40% oil content, are the preferred raw material for cold-pressed kachi ghani mustard oil, widely consumed across North India, Bangladesh and Pakistan. Low-erucic varieties are also available on request.
What is the minimum order quantity (MOQ) for mustard seeds export?
Our standard MOQ for mustard seeds is 500 kg per variety and packaging format. Custom-graded lots (specific sieve size, colour sorting or moisture conditioning) carry a 1 MT minimum. Smaller sample quantities are available on request.
