Post Approval Changes for Cosmetics in India: When Must You File, and What Are the Risks of Not Filing?

The Post-Market Compliance Gap

Obtaining a COS-2 Import registration certificate or a COS-8 manufacturing license is not the end of the regulatory journey in India — it is the beginning of the post-market compliance phase. Any change to the product, its labelling, its formulation, or its manufacturing details after registration must be formally notified to the relevant regulatory authority. Failure to file required Post Approval Changes (PACs) before commercialising the changed product is a regulatory violation.

In practice, PAC compliance is an area where many brands — particularly those with dynamic product portfolios that iterate formulations regularly — accumulate silent compliance gaps. This article explains the PAC framework for cosmetics in India: what changes require notification, which authority receives the notification, how to determine whether a change is major or minor, and the consequences of non-filing.

The Two-Authority PAC Structure

Post approval changes for Cosmetics in India are governed by two separate regulatory authorities depending on whether the product is imported (COS-2) or manufactured in India (COS-8/COS-9):

This means a brand that both Imports and manufactures in India may be filing PACs with two different authorities simultaneously for changes that affect both its Imported and domestically manufactured product lines.

What Constitutes a Post Approval Change?

A Post Approval Change is any modification to the product or its registration details that was not part of the original COS-2 or COS-8 application. Categories of PACs include:

Formulation Changes

• Addition of a new ingredient (preservative, active, fragrance component, colourant)
• Removal of an existing ingredient
• Change in the concentration of an existing ingredient beyond a defined minor variation threshold
• Change in the source supplier of a key ingredient (where the change affects specifications)
• Change in the manufacturing process that affects product quality specifications

Labelling Changes

• Change in Importer name, address, or entity
• Change in authorised agent
• Revised label claims

Legal Manufacturing Site Changes (for imported products)

• Change in the manufacturing site’s name or address following relocation or rebranding

Major vs. Minor Changes: How to Classify

Post approval changes are classified as major or minor based on their potential Impact on product safety, efficacy, and identity. While the Cosmetics Rules 2020 do not provide an exhaustive classification matrix equivalent to Pharmaceutical PAC guidelines, the following principles apply in practice:

The Consequences of Not Filing Required PACs

Selling a product in India that has undergone a change requiring a PAC filing — without that filing having been made and approved — constitutes a violation of the Cosmetics Rules 2020. The practical consequences can include:

• Regulatory enforcement action during CDSCO or State Licensing Authority market surveillance or inspection
• Confiscation of stock at Customs if the commercial invoice or label does not match the COS-2 registration details
• Complications at the time of COS-2 renewal if undeclared changes are detected during the retention review
• Reputational risk if enforcement action is made public

Beyond enforcement risk, undeclared formulation changes that introduce new ingredients or modify concentrations can also create consumer safety liability — particularly if the change involves preservatives, actives, or colourants with sensitisation potential.

Building a PAC Compliance Tracker

For brands with dynamic product portfolios, a structured PAC compliance tracker is an operational necessity, not a luxury. A functional tracker should maintain:

• A register of all India-registered products (COS-2 certificates and COS-8/9 licenses)
• A change log for each product — recording all formulation, label, and site changes with dates
• PAC filing status for each change — ‘filed’, ‘approved’, ‘pending’, or ‘not yet filed’
• An alert system that flags any product entering India commercial distribution after a change that has not yet received PAC clearance

Key Takeaways

• Any change to a registered Cosmetic — formulation, label, specification, Legal manufacturing site, or responsible party — requires a Post Approval Change filing
• PACs for imported cosmetics go to CDSCO; PACs for domestically manufactured cosmetics go to the relevant SLA
• Major changes require pre-approval before commercialisation; minor changes allow commercialisation during review
• Selling a product with an unfiled PAC is a regulatory violation — with enforcement, Customs, and renewal consequences
• A structured PAC compliance tracker is the most practical tool for managing post-market changes across a large India portfolio
