The eleven tests you cannot skip
Across heavy metals, microbial limits, physical characterisation and identity, FSSAI Nutra requires a minimum of eleven assays per production batch.
- ›Heavy metals: Pb, As, Cd, Hg (4 assays, atomic absorption)
- ›Microbial: TPC, yeast & mould, coliforms, E. coli, salmonella (5 assays)
- ›Physical: disintegration, dissolution, weight variation (3 assays)
- ›Chemical: identity assay for active ingredient (1 assay)
Per-batch cost stack
Per-batch cost in a FSSAI-notified Tier-1 lab runs ₹18,000 – ₹26,000 depending on actives. Across 3,000 units that is ₹6 – ₹9 per bottle on the COGS sheet.
Brands routinely model ₹2 – ₹3. The gap shows up at audit when the brand can't produce per-batch COAs and the auditor flags it.
Why most brands skip and regret
Cutting tests below the FSSAI minimum is the fastest way to lose your nutra licence. Recovery time after a notice is 6 – 9 months — long enough to kill momentum, burn cash and lose retail listings.
Two brands in our network lost licences in 2025 for missing assay documentation. Both were back in market only after 11 and 14 months respectively, at materially smaller scale.
Building a COA template
Build the COA template before you fill the first bottle. It saves weeks at audit and ensures the partner's lab knows exactly what to report.
Include batch number, manufacturing date, expiry, test method (USP / IP reference), result, specification, pass/fail, analyst signature, QC head signature. Print on partner letterhead.
Annual audit reality
FSSAI Nutra auditors visit annually and request 12 months of COAs at random. Brands that maintained per-batch COA discipline pass cleanly; brands that batched testing weekly or monthly fail and enter notice-period.
The fix is operational: hold the partner contractually to per-batch testing with COA delivery inside 7 days of release. Most partners will agree but most brands forget to write it down.
§ KEY TAKEAWAYS
- 01Bake batch-testing cost into COGS, never treat it as OPEX
- 02Use FSSAI-notified labs only — saves time at audit
- 03Build a COA template before you fill the first bottle
- 04Hold the partner contractually to per-batch testing
- 05Maintain a 12-month COA archive — auditors will ask
- 06Recovery from a licence notice is 6 – 9 months minimum
§ GLOSSARY
Technical jargon, acronyms and scientific terms used in this file — decoded.
- COA
- Certificate of Analysis — a batch-level document from the manufacturer listing tested specs (assay, micro, heavy metals, moisture).
- Heavy-metal panel
- Lab test screening lead, arsenic, cadmium and mercury — mandatory for nutraceuticals under FSSAI Schedule VIII.
- Microbial limits
- Maximum permitted CFU counts for TPC, yeast, mould and pathogens — defines product safety and shelf-life.
- Capsule shell
- The gelatin or HPMC sleeve that holds the powder fill. HPMC is vegetarian; gelatin is bovine/porcine.
- Blister pack
- Aluminium-PVC strip packaging for capsules — moisture-tight, child-resistant variants available.
