The CoA Is More Than a Quality Document — It Is a Regulatory Submission

In commercial practice, a Certificate of Analysis (CoA) is a quality control document — confirmation that a batch meets specification. In an NSF dossier submitted to FSSAI, the CoA is something more: it is the objective analytical evidence that defines what your product actually contains and demonstrates that it is free from contaminants at levels that could pose a risk to Indian consumers.

The distinction matters because the CoA you use for routine batch release is almost certainly not sufficient for an FSSAI NSF submission. Commercial CoAs typically cover a limited parameter set aligned with customer specifications. FSSAI’s Scientific Panel requires a comprehensive analytical dataset — covering nutritional composition, contaminants, microbiological status, stability, and in some cases naturally occurring toxicants — with every result referenced to a validated, internationally recognised analytical method.

This article walks through the complete Section C analytical requirements, with expert guidance on the parameters that most frequently generate Panel queries.

Section C Analytical Data Checklist

#	Parameter	Method Reference	Expert Note
C1	Nutritional composition — macros, micros, active ingredient per serving and per 100g	AOAC/ ISO/ IUPAC/ Food Chemicals CODEX/ BIS/ FAO-WHO	Method reference mandatory for every parameter. In-house method’ not accepted without full validation data.
C2	Heavy metals — Lead, Cadmium, Mercury, Arsenic etc.	ICP-OES, ICP-MS, AAS, AOAC, BIS/IS, ISO etc	Must comply with FSS (Contaminants, Toxins & Residues) Regulations Results must be below FSSAI Schedule limits. ICP-MS is Panel-preferred method for trace metals.
C3	Pesticide residues — multi-residue screen	Codex MRLs / FSSAI schedule	Must comply with FSS (Contaminants, Toxins & Residues) Regulations. Mandatory for plant-derived ingredients. Multi-residue screen minimum — targeted screen alone is insufficient.
C4	Microbiological parameters — TPC, Yeast & Mould, Enterobacteriaceae count, E.coli, Salmonella, Staph. Aureus etc.	IS 5402/ISO 4833, IS 5403/ ISO 21527 Part 1 and Part 2, ISO 21528 Part 2, IS 5887 Part3 / ISO 6579, IS 14988 Part 1 / ISO 11290-1 etc.	Must comply with Food Safety and Standards (Food Products Standards and Food Additives) Regulation, 2011.
C5	Mycotoxins — Aflatoxins B1/B2/G1/G2, Ochratoxin A, Fumonisins	ISO 23719 / ISO 16050/ FSSAI 07.015:2020	Mandatory for grain, nut, spice, and fermented ingredient applications. Botanical extracts frequently queried if absent.
C6	Solvent residues — Class 1/2/3 (where extraction solvents used)	Headspace Gas Chromatography (HS-GC), GC-MS adapted from AOAC 991.20, USP 467	Required for all solvent-extracted ingredients. Panel queries solvent residues if extraction process is described but residue data absent.
C7	Stability data — active ingredient content under proposed storage conditions	As per ICH Zone IVb at 30°C ± 2°C /75% RH ± 5% RH (Real Time) and 40°C ± 2°C /75% RH ± 5% RH (Accelerated)	Minimum 6 months accelerated or real-time 12 months preferred. Must cover proposed shelf life.
C8	Naturally occurring toxicants / anti-nutritional factors (where applicable)	AOAC / ISO/ CODEX, method-specific	E.g. Agaric acid, cyanogenic glycosides, lectins, oxalates, phytates for specific botanical and novel protein sources. If not applicable, state so explicitly.

The Method Reference Requirement — More Important Than It Appears

Every analytical result in your CoA must be accompanied by the method used to generate it. ‘In-house method’ is not acceptable as a standalone method reference in an FSSAI NSF submission. The Panel needs to assess whether the method is fit for purpose, validated, and recognised by international authorities.

Acceptable method references include AOAC International methods, ISO standards, USP compendial methods, Codex Alimentarius methods, IUPAC/ BIS/ FAO-WHO and FSSAI-approved methods. For each parameter, cite the specific method number and version — for example, AOAC 2013.06 for heavy metals by ICP-MS, or ISO 4833-1:2013 for aerobic plate count.

If a validated method does not exist for a specific parameter in your product matrix — which can happen for novel ingredients — you must submit full method validation data (linearity, precision, accuracy, LOD/LOQ, specificity) alongside the analytical results. This is a significant additional workload that should be identified and planned for during the pre-filing dossier gap analysis.

The Parameters That Most Frequently Generate Panel Queries

Heavy Metals — ICP-MS Is the Preferred Method

Heavy metal testing is mandatory for all NSF applications. FSSAI’s Scientific Panels have a clear preference for ICP-MS (Inductively Coupled Plasma Mass Spectrometry) methodology — it offers the lowest detection limits and the best specificity for lead, cadmium, mercury, and arsenic. Results reported from older AAS (Atomic Absorption Spectrometry) methods may be queried if detection limits are not adequate for FSSAI schedule limit verification.

Ensure your results are reported in µg/kg (ppb) and compared explicitly against FSSAI contaminant limits for your product category. A CoA that presents results without regulatory limit comparison forces the Panel to do the comparison themselves — and may result in a query if the Panel’s reference limit differs from what you assumed.

Pesticide Residues — Multi-Residue Screen Is the Minimum

For plant-derived ingredients, a targeted pesticide screen covering only a handful of compounds is insufficient. FSSAI expects a multi-residue screen — typically 200+ pesticides — consistent with Food Safety and Standards (Contaminants, Toxins and Residues) Regulation, 2011. Many applicants submit targeted screens covering only the pesticides they believe were used in the crop’s production. The Panel will query this limitation.

Stability Data — Start Early

Stability data is one of the most common causes of application delays — not because applicants forget to include it, but because they do not start the studies early enough. Minimum 6 months of accelerated stability data (40°C/75% RH for solid dosage forms per ICH Zone IVb) or real-time data under proposed storage conditions must be available at the time of filing. If your stability studies are still ongoing when you plan to file, your filing date must be deferred until at least 6 months of data is available.

Begin stability studies 7–8 months before your planned filing date — not when the dossier is otherwise complete.

Mycotoxins — Do Not Assume Irrelevance

Mycotoxin contamination is a real risk for plant-derived, grain-derived, and fermented ingredients — and FSSAI’s Scientific Panels are alert to it. Many applicants in the supplement space omit mycotoxin data on the assumption that it is irrelevant to their ingredient. If the ingredient has any botanical or fermented origin, include mycotoxin data proactively. The cost of an additional testing is negligible compared to the timeline cost of a Panel query.

Laboratory Accreditation — NABL/ ILAC or ISO/IEC 17025

FSSAI strongly prefers CoAs from National Accreditation Board for Testing and Calibration Laboratories /International Laboratory Accreditation Cooperation, accredited laboratories (India’s National Accreditation Board for Testing and Calibration Laboratories). For foreign manufacturers, CoAs from ISO/IEC 17025 accredited laboratories are accepted — but the laboratory’s accreditation certificate and scope of accreditation must be submitted alongside the CoA. The accreditation scope must explicitly cover the parameters being tested and the relevant matrices.

A CoA from a non-accredited laboratory — even a reputable one — will generate a query and may require re-testing at an accredited facility, adding 4–8 weeks to your timeline.
