Product ID
Lot or batch number, product name, and internal SKU so the CoA maps precisely to the tested material and production record.
A clear, consistent CoA reduces release delays, supports regulatory compliance, and creates an auditable record that links test data to product lots. A well‑designed template lowers rework, speeds customer approvals, and helps teams demonstrate conformity during inspections or supplier audits.
Lot or batch number, product name, and internal SKU so the CoA maps precisely to the tested material and production record.
Sample type, date and time collected, collector name, and chain‑of‑custody references that demonstrate sample integrity from collection through analysis.
Analytical method identifiers, version or SOP numbers, instruments used, and method reference so results are reproducible and auditable.
Measured values, units, limits or acceptance criteria, and result flags (pass/fail) presented in a structured table for quick review and machine parsing.
Laboratory accreditation, certificate numbers or scope (e.g., ISO/IEC 17025) and any regulatory identifiers required by the receiving authority.
Authorized signer name, job title, signature date, and any required witness or notarization entries for legal or customer requirements.

Turnaround depends on tests; from same day to several business days
Allow one business day for QA review in standard workflows
Signer should complete approval within available release window
Deliver signed CoA immediately after approval
Define and document expedited handling in SOPs
Verify identity, record chain of custody, and assign internal ID.
Complete analytical tests according to the indicated SOPs.
Quality reviews methods, calculations, and any deviations.
Authorized signer approves CoA and triggers distribution.
A QA Manager or Quality Assurance designee is commonly authorized to review analytical results, confirm acceptance criteria have been met, and sign the CoA. Their signature attests that the test methods and results were reviewed according to the laboratory's SOPs and that the product lot is released under specified conditions.
The Laboratory Director or Technical Lead often has final approval authority for complex or out‑of‑specification results. They document method deviations, approve corrective actions, and certify that the laboratory followed accredited procedures before signing and dating the CoA.
Optica standardized templates to reduce review cycles and customer queries.
Martin Properties migrated paper certificates to a fully digital workflow to support remote inspections.
