Certificates
How East Coast Labs uses Certificates of Analysis.
A COA link on East Coast Labs means a product-owned document has been attached to that record. If no COA is attached, the page represents that absence plainly rather than implying a fallback.
Attached COA
On East Coast Labs, a live COA link means a PDF has been attached to the exact product record in view. It is meant to support that record's documented batch and release context.
Scope of proof
A COA can support analytical and release information for a specific record, but it does not automatically answer every handling, shipping, or support question on its own.
Missing documentation
If no COA has been attached, East Coast Labs shows that gap directly on the record instead of replacing it with decorative brand-level assurance.
What to expect
A COA should feel tied to the record, not bolted onto it.
When a COA is attached, the document should make sense alongside the record's visible fields such as purity result, analytical method, batch or lot, analysis date, and release date. The value of the document comes from that alignment.
East Coast Labs uses the product page as the place where certificate access is declared. Researchers should not have to guess whether the record has a document attached or open a support ticket just to discover whether the file exists.
COAs and other records
Not every supporting document is a COA.
East Coast Labs can also attach other product-owned reference documents that add handling, release, or record context. Those files should be read as supporting record documents with their own purpose, not as automatic substitutes for a Certificate of Analysis.
That distinction matters because a COA answers one kind of question, while storage notes, release commentary, and support guidance answer others. The storefront keeps those document types separate so the record stays legible.
Related guides
A COA link only makes sense inside the broader guide layer, where testing terminology, storage handling, glossary definitions, and product-level release context stay aligned.
