What Is a Certificate of Product Analysis in the Philippines
A Certificate of Product Analysis (COA) is a document issued by the manufacturer confirming that a specific batch of product meets its approved specifications. It is one of the most frequently requested documents in Philippine product manufacturing and FDA registration.
This guide explains what a COA is, what it contains, why you need it, and how to obtain one from your manufacturer.

What Is a Certificate of Product Analysis
A COA is a batch-specific document produced by the manufacturer's quality control department. It confirms that the batch was tested, the test results were within the approved specification limits, and the batch is released for sale or use.
The COA is not a regulatory certificate issued by the FDA. It is a quality document issued by the manufacturer. However, the Philippine FDA requires it as supporting documentation for product notification or registration because it demonstrates that the specific batch has been tested and meets quality standards. For an overview of FDA requirements in contract manufacturing, see Contract Manufacturing FDA Requirements Philippines.
Why You Need a COA in the Philippines
Brand owners need a COA for two primary purposes.
First, for FDA product notification or registration. The Philippine FDA requires documentation that the product has been tested and meets specifications before it can be notified or registered for sale. The COA provides this evidence for the specific batch you are registering.
Second, for due diligence by buyers, distributors, or retailers. Institutional buyers, pharmacy chains, and some marketplace sellers require COA documentation before stocking a product. Having a COA readily available speeds up the process of getting listed with these buyers.

What Information a COA Contains
A standard COA for a cosmetic or personal care product in the Philippines includes:
Product name and product code. The name of the finished product and the manufacturer's internal product code.
Batch number and batch size. The unique identifier for the specific production batch and the total quantity produced in that batch.
Date of manufacture and expiry date. The date the batch was produced and the calculated expiry date based on stability data.
Test parameters and results. The specific tests conducted, the specification limits, and the actual test results for the batch. Typical parameters include appearance, color, odor, pH, viscosity, and microbial testing (total plate count, yeast and mold count, and absence of specified pathogens).
Release status. Confirmation that the batch passed all tests and is released for distribution.
Authorized signature. The COA is signed by the manufacturer's QC manager or authorized quality representative.

How a COA Is Used for FDA Registration
When you submit a product for FDA notification or registration in the Philippines, the COA is included in your supporting documentation package. It provides evidence that the specific product has been manufactured, tested, and meets quality standards.
The FDA reviewer uses the COA to confirm that the product's physical and chemical properties are consistent with what was declared in the product notification. If test results in the COA fall outside acceptable ranges, the notification may be rejected or held pending clarification.
For cosmetics products manufactured at Orsolab, COAs are issued for every batch and are available as part of the standard documentation package for FDA notification. Orsolab holds FDA LTO No. LTO-3000006301418 and is GMP-certified by the Philippine FDA, meaning the COA is issued from an audited, compliant facility.
For more context on GMP certification and why it matters for COA credibility, see GMP Certified Manufacturer Philippines.
Who Issues the COA
The COA is issued by the manufacturer, specifically by the quality control or quality assurance department. It must be issued by a GMP-certified manufacturer to carry full regulatory weight.
The brand owner does not issue the COA. You receive it from your manufacturer after each production batch is tested and released. If you are working with a manufacturer who does not issue COAs or who issues incomplete COAs without test data, that is a significant compliance risk.
When evaluating manufacturers, ask to see a sample COA from a previous batch. This tells you whether their documentation is complete, legible, and professional. For more on what to look for in a manufacturer, see Contract Manufacturing Philippines.
How Long a COA Is Valid
A COA documents the test results for a specific batch at the time of manufacture. It is batch-specific and does not expire in the legal sense, but it only applies to the specific batch it was issued for.
A COA for Batch 001 is not valid for Batch 002. Each new production batch requires its own COA. For FDA registration purposes, the COA must correspond to the specific batch you are submitting documentation for.
Stability testing results, which are sometimes included as part of the COA or as a separate stability report, may carry their own validity period defined by the study protocol.
How to Request a COA From Your Manufacturer
Request the COA as part of your standard batch acceptance process. After the manufacturer releases a batch, the COA should be available before or at the time of delivery.
Specify in your supply agreement or purchase order that a COA is required before you will accept the batch. This ensures the manufacturer treats it as a standard deliverable rather than an afterthought.
Orsolab issues COAs for every batch produced at the Tanza, Cavite facility, approximately 45 minutes from Metro Manila via CAVITEX. COAs are included in the documentation package provided to clients for FDA notification and quality record purposes.

FAQs
What is the difference between a COA and FDA registration in the Philippines?
A COA (Certificate of Product Analysis) is a quality document issued by the manufacturer confirming that a specific batch meets its approved specifications. FDA registration is a regulatory approval issued by the Philippine FDA allowing the product to be sold. The COA is one of the supporting documents submitted to the FDA as part of the product notification or registration process.
Do I need a separate COA for each production batch?
Yes. A COA is batch-specific. Each production batch receives its own unique batch number and its own COA reflecting the test results for that specific batch. A COA from a previous batch cannot be used as documentation for a different batch.
Can any manufacturer issue a COA, or does it need to come from a GMP-certified facility?
Any manufacturer can technically issue a document called a COA. However, for Philippine FDA registration and for acceptance by most buyers, the COA should come from a GMP-certified manufacturer. GMP certification means the manufacturer's QC procedures and documentation have been audited and approved by the FDA. Orsolab is GMP-certified by the Philippine FDA.
