A COA or specification sheet is a documentation file that summarizes product and batch information. Buyers often use these files for procurement records, receiving checks, and internal documentation.
Fields and formats can vary by supplier, but many documents include similar sections.
Common COA / Specification Sheet Fields
Product Name
The product name identifies the item the document refers to. Compare it with the product page, invoice, or order confirmation.
SKU or Catalog Number
The SKU or catalog number helps distinguish similar items, sizes, or formats.
Batch / Lot Number
The batch or lot number connects the document to a specific production or packaging batch. If you are matching a document to an order, this is one of the most important fields.
Date Fields
COA/spec documents may include preparation, review, release, or document dates. Date labels vary by supplier.
Identity
Identity testing is used to confirm that the documented item matches the expected product identity according to the method listed on the document.
Purity or Assay
Purity or assay fields summarize measured results according to the listed method and acceptance criteria. The exact terminology depends on the product and test format.
Test Method Labels
Method labels may refer to internal methods, compendial methods, or instrument-based methods. The COA/spec sheet should identify the method used for each listed result when available.
Acceptance Criteria
Acceptance criteria describe the documented specification or expected range for a listed test.
Result
The result field shows the recorded value or status for the test listed in that row.
How to Compare a COA to Your Order
Start with the product name and SKU. Then compare the batch/lot number, if available. If anything is unclear, request clarification from the supplier using the order number or purchase email.
When to Request Documentation
Request COA/spec documentation when you need product or batch documentation for purchasing records, vendor review, receiving workflows, or internal files.
