Sesame and Mustard Oil Sourcing in India: Specification Guide
Traditional oils are among the most adulterated commodities in the Indian market, and the adulteration is economically motivated. Extraction method, free fatty acid value and adulteration screening are the specification points. Edible and cosmetic use have different requirements.
What to Establish First
This guide is for brand owners sourcing sesame, mustard and similar traditional oils in India, for edible or cosmetic use.
Two things before specification. First, whether the oil is for edible or cosmetic use, since the licensing route, specification priorities and testing requirements differ. A single product marketed for both must satisfy both.
Second, the extraction method. Cold pressed, wood pressed, expeller pressed and refined oils are different products with different costs and characters, and the terms are used loosely. Cold pressed and wood pressed are claims about process that buyers pay a premium for, so establish the basis and retain documentation rather than accepting the description.
Adulteration Is the Central Risk
This is the point that distinguishes sourcing these oils from sourcing most ingredients.
Traditional oils command a premium over commodity refined oils, which creates economic incentive for blending. Adulteration with cheaper oils has been the subject of substantial regulatory attention in India, and basic parameters do not reliably detect it.
Require adulteration screening appropriate to the oil, with named methods, per batch rather than as a one-off supplier assurance. Ask specifically which adulterants each method detects, since techniques differ in what they can identify.
Independent verification of received batches is worth budgeting for here. It is the only check that does not rely on the supplier’s own reporting, and in a category with this risk profile it is proportionate.
Specification Elements
What belongs in your purchase specification.
| Element | What to Specify | Why |
|---|---|---|
| Oil type | Named, single oil | Basis of the product |
| Extraction method | Cold, wood, expeller or refined | Determines product and claim |
| Adulteration screening | Per batch, methods named | The central risk |
| Fatty acid profile | Target, method named | Authenticity and composition |
| Free fatty acid value | Maximum | Quality and processing indicator |
| Peroxide value | Limit at release and expiry | Oxidation measure |
| Moisture and insoluble impurities | Maximum | Quality indicator |
| Colour and aroma | Target with variation | Distinctive and informative |
| Heavy metals | Limits per batch | Standard |
| Pesticide residues | Per sourcing and market | Often required |
| Pack | Material, closure, light protection | Oxidation and leakage |
| Antioxidant system | Disclosed if used | Must be declared |
Fatty acid profile serves double duty here: it verifies composition and it is one of the indicators that can reveal blending with a different oil.
Edible Versus Cosmetic Use
The decision affects requirements throughout.
Edible Use
Food framework licensing, food-grade specification, and the full quality parameter set including free fatty acids and moisture.
Cosmetic Use
Cosmetic manufacturing licence for the product type, with cosmetic claim limits and safety assessment considerations.
Both
A product marketed for both must satisfy both routes. Obtain professional advice rather than assuming overlap.
Mustard Oil Specifically
Requirements and permissions for mustard oil vary by jurisdiction and intended use. Obtain professional advice for your market and application.
The last point matters: mustard oil’s regulatory position for edible use differs between markets, which affects both domestic positioning and any export plan.
Claim Limits
Traditional oils attract broad claims.
For an edible product under the food framework, no claim to treat, cure or prevent any condition is available, which excludes heart health claims, cholesterol claims and the therapeutic uses associated with these oils traditionally.
For a cosmetic product, claims are limited to appearance, skin or hair feel and moisturisation, and treating any condition is not available.
Cold pressed, wood pressed and single-origin claims are factual claims about process and source requiring documentation. If you cannot document it, do not claim it.
Sourcing Checklist
Complete before a first order.
- Decide edible, cosmetic or both, and confirm licensing for each.
- Obtain professional advice on requirements for your specific oil and use.
- Specify the oil type and extraction method.
- Obtain documentation supporting any cold or wood pressed claim.
- Require adulteration screening per batch with named methods.
- Ask which adulterants each method detects.
- Specify the fatty acid profile with a named method.
- Specify free fatty acid, peroxide value, moisture and impurity limits.
- Require disclosure of any antioxidant system.
- Agree heavy metal limits and pesticide screening scope.
- Investigate any price materially below market.
- Budget periodic independent verification.
- Require retained samples of every batch.
- Specify light-protective packaging and a secure closure.
- Generate stability data with sensory assessment.
- Write a claim set appropriate to the route, excluding health claims.

Frequently Asked Questions
What is the central risk in sourcing traditional oils?
Adulteration with cheaper oils, which is economically motivated and has been the subject of substantial regulatory attention in India. Basic quality parameters do not reliably detect it, so adulteration screening with named methods per batch is necessary.
What should I specify about extraction?
The method explicitly: cold pressed, wood pressed, expeller pressed or refined. These are different products at different costs, the terms are used loosely, and cold or wood pressed are process claims requiring documentation.
Why does the fatty acid profile matter?
It serves double duty: verifying composition and acting as one of the indicators that can reveal blending with a different oil. Specify it with a named test method rather than accepting a general specification sheet.
Does edible or cosmetic use change the requirements?
Substantially. Edible use follows the food framework with its full quality parameter set; cosmetic use requires a cosmetic manufacturing licence with cosmetic claim limits. A product marketed for both must satisfy both routes.
Can I claim cold pressed or single origin?
Only with documentation supporting it. These are factual claims about process and source that buyers pay a premium for, so establish the basis and retain the evidence rather than accepting a supplier description.
