Batch Reports and Certificate Library
To request a certificate of analysis (CoA) or batch report from Knockout Labs, give the product name and the lot code printed on the container. If you are checking a product before buying, send its catalogue link and ask which lot the available report covers.
Request a batch reportIdentify the lot in your request
| Your situation | Details to include | Question to ask |
|---|---|---|
| Before ordering | Product name, product-page link and intended variant or fill | Which lot is being offered, and what documents are available for it? |
| Material already received | Product name, exact lot code and order reference if available. Keep a readable label photograph for follow-up. | Which report and specification apply to this container? |
| An older lot | Original product and lot details, order reference if available, and any report identifier already held | Is the original record retrievable, and has a later version replaced it? |
Copy the lot code exactly, including any prefix or suffix. If a character is unclear, quote the readable part and tell support which character you cannot make out. An order reference helps locate the transaction, but one order can contain more than one lot.
Include the question the report needs to answer
On the contact form, select Batch report or COA. Put the identifier you have in “Order or batch reference”. Use the message to name the product, the lot or variant, and the particular result you need.
Before buying. A useful request is “Which lot is being offered for this product, and is a current CoA available for that lot? I need to check the identity test and its reported result.” Include the product link and labelled amount.
With a container. After giving the lot code, ask “Which report number and revision cover this container? Please identify the sample reference and the method used for the reported purity result.” If you have a label photo or a report to share, ask how to send it.
If the question turns on how a result was obtained, specify what you need to see, such as the chromatogram behind an area percentage. The analytical methods guide explains the kinds of records a method can produce. Confirm availability for the named lot.
Check a supplied document before relying on it
- Match product, form and lot using the certificate-to-batch guide.
- Identify who issued the document and who performed the analysis. Manufacturer and independent testing explain the distinction.
- Check the report identifier, issue date, version and complete page set. Ask whether a later issue replaces the copy you hold.
- Read the stated tests, results and criteria together. For a purity claim, confirm the method and reporting basis rather than relying on the headline percentage.
ICH Q7 describes batch identifiers, tests, acceptance limits and numerical results for pharmaceutical API certificates. Use those fields as a reading checklist. The actual report tells you which tests were performed for the lot in question. [A3]
Distinguish unavailable, archived and superseded records
| Record status | What it means for your review | Next step |
|---|---|---|
| Not supplied or not listed | The requested evidence is not available to you through this page or response. | Ask whether it exists, is pending or cannot be provided; leave the result unconfirmed. |
| Archived lot record | The document concerns a historical lot. Age alone does not establish that it was replaced. | Verify the exact lot and applicable version; do not apply it to current stock. |
| Superseded report | A later issue replaces the earlier document. | Retain the version history and ask what changed. |
| Mismatched or incomplete record | A lot, sample, page or other necessary connection is unresolved. | Identify the discrepancy and request clarification before treating it as evidence for your material. |
For an older lot, keep the original report number and ask whether a later revision replaced it. If a report is supplied for internal review, check with the issuer before sharing it more widely. If no result is supplied, record the field as unresolved. An out-of-specification result requires a reported result and an applicable criterion.
If the document's connection to the submitted sample is unclear, consult chain of custody. A laboratory result and a batch-release decision also serve different purposes. Return to the quality hub for the broader document routes.
