Specific Migration Testing Services in India
NABL-accredited testing that identifies and quantifies the exact chemical substances migrating from your packaging — BPA, phthalates, heavy metals, and more — against legally defined Specific Migration Limits (SMLs).
The Fair Labs is a NABL ISO/IEC 17025 accredited testing laboratory helping food, beverage, pharmaceutical, cosmetic, and packaging manufacturers across India verify that their packaging materials are safe, compliant, and export-ready.
Every food and beverage product sold today is in constant chemical contact with its packaging. Plastics, inks, adhesives, coatings, and laminates are formulated using a wide range of additives, monomers, catalysts, and stabilizers — and under real-world conditions of storage, heat, and time, trace amounts of these substances can migrate out of the packaging and into the food or beverage it contains. Specific Migration Testing is the scientific process used to identify and quantify exactly which individual chemical substances are migrating, and in what amount, from a packaging material into food.
Unlike a general pass/fail check, specific migration testing isolates and measures named substances — such as Bisphenol A, phthalates, primary aromatic amines, or heavy metals — against legally defined Specific Migration Limits (SMLs). This substance-by-substance approach is essential because different chemicals carry different toxicological risk profiles, and a packaging material that passes an overall migration check can still fail on an individual substance if that substance is present in concentrations that exceed its specific regulatory threshold.
For manufacturers, specific migration testing is not a regulatory formality — it is a core pillar of product safety strategy. It protects consumers from long-term, low-dose chemical exposure; it satisfies the documentary requirements of FSSAI, BIS, EU, and US FDA frameworks; it shields brands from recalls, litigation, and reputational damage; and it is frequently a non-negotiable prerequisite for retailers, private-label buyers, and export customers. As global food safety enforcement tightens and as Indian manufacturers increasingly compete in EU, US, and Gulf markets, specific migration testing has moved from "good practice" to commercial necessity.
The Fair Labs operates a NABL-accredited specific migration testing laboratory equipped to test plastic, flexible, paper, and multilayer packaging against FSSAI, BIS, EU, and US FDA frameworks, giving manufacturers a single, scientifically defensible report they can rely on for domestic compliance and export documentation alike.
What is Specific Migration Testing?
Specific Migration Testing is an analytical procedure used to measure the quantity of a named, individual chemical substance that transfer from a food contact material into food or an approved food simulant, under defined conditions of temperature and time that replicate real-world use.
What is a Specific Migration Limit (SML)?
A Specific Migration Limit (SML) is the maximum permissible quantity of a particular substance — for example, a monomer, additive, or processing aid used in plastic manufacturing — that is allowed to migrate from a packaging material into food, usually expressed in milligrams per kilogram (mg/kg) of food or food simulant. SMLs are set by toxicological risk assessment for each substance individually, which is why different chemicals have very different limits depending on their hazard profile.
Overall Migration vs. Specific Migration: What's the Difference?
This distinction is one of the most commonly misunderstood areas of food contact compliance, so it's worth stating plainly:
| Parameter | Overall Migration Testing | Specific Migration Testing |
|---|---|---|
| What it measures | The total mass of all non-volatile substances that migrate from packaging into food simulants | The quantity of one specific, named substance migrating into food or simulant |
| Purpose | Screens overall inertness of the packaging material | Confirms compliance with the legal limit for an individual hazardous substance |
| Result expressed as | mg/kg or mg/dm² (total migrate) | mg/kg for the named substance |
| Indian reference standard | IS 9845 | Substance-specific SML tables under FSSAI Packaging Regulations |
| Typical question answered | "Is this packaging material chemically inert overall?" | "Is the BPA / formaldehyde / lead level in this packaging within the legal limit?" |
A packaging material can comfortably pass overall migration testing and still contain a single substance, such as a heavy metal or a residual monomer, present in a concentration that breaches its individual SML. This is precisely why regulators worldwide require both tests — overall migration as a general inertness screen, and specific migration testing as a targeted, substance-level safety check.
Why Individual Substances Require Separate Testing
Each chemical used in food contact material manufacturing — plasticizers, stabilizers, antioxidants, residual monomers, colorants — has a distinct toxicological profile, absorption behavior, and risk threshold. A generic "total migration" number cannot tell a regulator, a brand owner, or a consumer whether a specific carcinogenic or endocrine-disrupting substance is present above a safe level. Specific migration testing uses targeted analytical chemistry (LC-MS/MS, GC-MS/MS, ICP-MS, and related techniques) to detect and quantify these substances individually, often down to trace (parts-per-billion) levels.
Migration Under Intended Conditions of Use
Specific migration testing is always conducted under conditions that simulate the actual intended use of the packaging — including contact time, contact temperature, and the nature of the food (aqueous, acidic, fatty, alcoholic, or dry). A container intended for hot-fill beverages, for instance, is tested under conditions that reflect that thermal exposure, since migration rates increase significantly with temperature and contact duration.
Food Simulants
Because testing actual food products for every possible substance is impractical and analytically difficult, regulators specify standardized food simulants that mimic the chemical behavior of different food categories:
- Distilled water — simulates aqueous, non-acidic foods
- 3% acetic acid — simulates acidic foods
- 10% or 20% ethanol — simulates alcoholic and certain aqueous foods
- Olive oil / iso-octane / Tenax — simulates fatty foods
Selecting the correct simulant (or combination of simulants) based on the food category and packaging end-use is a critical first step in generating a scientifically valid and regulator-accepted migration test report.
Packaging Safety Evaluation
Taken together, specific migration testing forms part of a comprehensive packaging safety evaluation — confirming not just that a material looks and performs correctly, but that it is chemically safe for its intended food contact application across its expected shelf life and usage conditions.
Why Specific Migration Testing Matters
Food Safety
Chemical migration from packaging is a recognized route of low-dose, long-term human exposure to substances such as endocrine disruptors, heavy metals, and carcinogenic amines. Specific migration testing is the primary scientific tool for detecting and controlling this exposure pathway.
Regulatory Compliance
FSSAI, BIS, the European Union, and the US FDA all require food contact materials to demonstrate compliance with specific migration limits before they can legally be placed on the market. Non-compliance can result in product seizure, license suspension, financial penalties, and forced recalls.
Prevention of Chemical Contamination
Migration testing identifies contamination risks originating from raw materials, additives, printing inks, adhesives, and recycled content — risks that are often invisible without laboratory analysis.
Consumer Health Protection
Many substances regulated under SML frameworks — including BPA, certain phthalates, and primary aromatic amines — are linked to endocrine disruption, carcinogenicity, or organ toxicity at elevated exposure levels.
Import and Export Compliance
Products exported to the EU, US, UK, Gulf Cooperation Council countries, or other regulated markets must typically be accompanied by specific migration test reports that satisfy the destination market's regulatory framework.
Retailer Requirements
Organized retail chains, e-commerce marketplaces, and private-label buyers increasingly mandate third-party migration test reports as a condition of vendor onboarding.
Product Quality Assurance
Migration testing data also supports formulation and material selection decisions, helping manufacturers identify safer raw material and additive combinations early in product development — reducing the risk of costly reformulation after launch.
Compliance Insight: A product that is fully compliant on labelling, nutrition, and shelf-life parameters can still be non-compliant — and legally unsellable — if its packaging fails specific migration testing. Packaging compliance is a parallel, equally enforceable requirement under Indian food law.
Regulations & Standards
Specific migration limits are not uniform across the world — each regulatory body defines its own list of regulated substances, permissible limits, and approved testing methodologies. Manufacturers selling across multiple markets must structure their testing program around every applicable destination market, not just their home jurisdiction.
FSSAI Regulations (India)
The Food Safety and Standards (Packaging) Regulations, 2018, notified by the Food Safety and Standards Authority of India, govern food contact packaging materials in India. These regulations prescribe both an overall migration limit and specific migration limits of contaminants for plastic packaging materials, in addition to general and material-specific requirements for paper, glass, metal, and plastic packaging. Under these regulations, the "specific migration limit" is defined as the maximum permitted amount of a given substance released from a material or article into food or food simulants.
Compliance with these regulations has been mandatory for food business operators since 1 July 2019. FSSAI has made it mandatory for FBOs to obtain a certificate of conformity issued by a NABL-accredited laboratory against the requirements specified in the regulation's schedules. The framework has continued to evolve: FSSAI has amended the Packaging Regulations to add antimony and DEHP (a commonly used phthalate plasticizer) as substances subject to specific migration limits for plastic materials intended to come into contact with food.
Specific migration limits under the FSSAI framework cover a defined list of contaminants. For example, specific migration limits are prescribed for substances such as barium 1.0 mg/kg, copper 5.0 mg/kg, and zinc 25.0 mg/kg, among others listed in the regulation's tables.
BIS Standards
Packaging materials regulated under FSSAI must also conform to the relevant Bureau of Indian Standards (BIS) specifications referenced in the regulation's schedules, covering material categories including plastics, paper and paperboard, glass, and metals. These include standards such as IS 6622 for greaseproof paper and IS 1993 for tin plate, alongside the plastics-specific standards referenced for polymer packaging. Pigments and colorants used in food contact plastics are separately required to conform to IS 9833.
IS 9845 (Overall Migration Reference Standard)
While IS 9845 governs overall migration testing rather than specific migration, it remains foundational context for any food contact compliance program. Plastic packaging materials are required to pass the prescribed overall migration limit of 60 mg/kg or 10 mg/dm² when tested as per IS 9845, with no visible colour migration, before specific migration parameters are even assessed. Laboratories typically conduct overall migration screening alongside specific migration testing to give manufacturers a complete compliance picture.
EU Regulation (EU) No. 10/2011
For manufacturers exporting to the European Union, Commission Regulation (EU) No. 10/2011 on plastic materials and articles intended to come into contact with food is the controlling framework. It establishes a positive list of authorized monomers and additives, each with its own SML or SML(T) (group limit), along with prescribed testing conditions, simulants, and migration test methodologies. Compliance with this regulation is typically required as part of a Declaration of Compliance (DoC) accompanying any plastic food contact material placed on the EU market.
Framework Regulation (EC) No. 1935/2004
This is the EU's overarching framework regulation covering all materials and articles intended to come into contact with food — not just plastics. It establishes the core principle that food contact materials must not transfer their constituents to food in quantities that endanger human health, change food composition unacceptably, or deteriorate food's organoleptic characteristics. (EU) No. 10/2011 operates as a specific implementing measure under this broader framework for plastics.
US FDA Food Contact Material Regulations
In the United States, food contact substances are regulated under the Federal Food, Drug, and Cosmetic Act, primarily through FDA regulations covering indirect food additives (21 CFR Parts 174–186) and the Food Contact Substance Notification (FCN) program. Migration testing conducted to FDA-aligned protocols and conditions of use is typically required to support FCN submissions or to substantiate that a packaging material's components fall within FDA-authorized use conditions and concentration limits.
Why Destination-Specific Compliance Matters
Because SMLs, regulated substance lists, approved simulants, and even permitted test methodologies differ between FSSAI, EU, and US FDA frameworks, a packaging material compliant for the Indian domestic market is not automatically compliant for export. Manufacturers selling into multiple geographies need a testing partner capable of structuring migration test programs against each destination market's specific requirements — rather than assuming one generic test report will satisfy every regulator.
Common Substances Tested
The table below summarizes the substances most frequently assessed under specific migration testing programs, the packaging types where they are most relevant, and the principal health concerns driving regulatory scrutiny.

Frequently Asked Questions
Specific migration testing is a laboratory procedure that measures the quantity of a named, individual chemical substance migrating from a food contact packaging material into food or an approved food simulant, under conditions that replicate real-world use, and compares the result against the substance's legally defined Specific Migration Limit (SML).
The Specific Migration Limit is the maximum permitted concentration of a particular substance allowed to migrate from a packaging material into food, typically expressed in mg/kg. SMLs are set individually for each regulated substance based on its toxicological risk profile.
Overall migration testing measures the total mass of all non-volatile substances migrating from packaging into food simulants, providing a general inertness check. Specific migration testing measures one named substance at a time against its own individual regulatory limit. Both are typically required for full compliance.
Yes, for food contact materials placed on the Indian market, FSSAI's Packaging Regulations require compliance with specified specific migration limits, in addition to overall migration requirements. Export markets including the EU and US impose their own mandatory specific migration testing requirements under their respective frameworks.
Commonly tested substances include Bisphenol A (BPA), phthalates, formaldehyde, melamine, primary aromatic amines, vinyl chloride monomer, acrylonitrile, styrene, epoxy derivatives, plasticizers, antioxidants, UV stabilizers, tin-based stabilizers, and heavy metals such as lead, cadmium, chromium, and mercury. The specific panel depends on the packaging material and its intended use.
Plastic, flexible, laminate, and multilayer packaging materials in direct food contact typically require specific migration testing, including PET bottles, HDPE/LDPE containers, polypropylene containers, films, caps, closures, trays, cups, and plastic-coated paper or paperboard.
In India, the FSSAI Food Safety and Standards (Packaging) Regulations, 2018, supported by relevant BIS standards, govern specific migration requirements. For export, Regulation (EU) No. 10/2011 and Framework Regulation (EC) No. 1935/2004 apply for the European Union, while US FDA food contact substance regulations apply for the United States market.
Turnaround time depends on the packaging material, the substance panel required, and the applicable regulatory framework. Our team confirms expected turnaround at the time of sample submission based on your specific testing requirements.
