Certificate of Analysis (COA) in Export Documentation
Beyond its quality-control role, the Certificate of Analysis is often a required document under a sales contract or Letter of Credit. This guide covers its documentation role specifically.
The COA's role in the document set
Where a sales contract or LC requires a Certificate of Analysis, it typically needs to match the agreed specification exactly in the parameters tested, and be issued by a lab or party named or acceptable under the contract terms.
Under an LC, a COA that references different parameters, units, or an unnamed lab than what the LC specifies can be treated as a discrepancy, potentially delaying or blocking payment — see the LC Document Verification Protocol.
What banks and buyers check
Reviewers typically check that the COA identifies the correct shipment/batch, reports the exact parameters and limits specified in the contract or LC, and is dated and signed consistently with other shipping documents.
Practical tips for exporters
Agree the exact COA parameters, units and issuing lab with the buyer at the specification stage (see the Product Specification Protocol), not at the point of shipment — this avoids late discrepancies that can delay document presentation.
Key Takeaways
- A COA required under an LC must match the LC's specified parameters, units and lab exactly to avoid a documentary discrepancy.
- Agree COA requirements at the specification stage, not after production is complete.
- The COA's quality-control role and its documentation-compliance role are related but distinct — both matter.
FAQ
Can I substitute a different lab's COA if my usual lab is unavailable?
Only if the contract or LC does not name a specific lab, or if the buyer/bank agrees to the substitution in writing. Check the exact wording before assuming a substitution is acceptable.
Does a COA guarantee LC payment?
No — it is one of potentially several required documents. Payment depends on the full document set complying exactly with the LC's terms, not any single document alone.
