A Batch Has a History.
FDA’s supplement guidance describes batch records that identify equipment, components, processing information, and testing or examination results, either directly or through references. These records connect individual operations to a particular production batch. [Source]
Start with the Bottle in Your Hand.
When contacting a brand, provide the exact product name and lot or batch number printed on the bottle. A clear photo of that area can help avoid a transcription mistake. Keep your order number too, if your question also concerns a purchase.
Read the Document in Context.
If you receive a test report or certificate of analysis, begin with the product or material identified, the lot, the date, and the tests reported. Ask the team to explain unfamiliar terms. Do not assume a document covers another formula or every batch from the same brand.
Ask What Can Be Shared.
A useful request is: “What product or batch documentation is available for this bottle?” Records can contain information that is not part of a public consumer report. Clarify the document’s scope and any unanswered questions before treating it as a general assurance.
The product name identifies the formula. The lot number helps narrow the conversation to your bottle’s batch.
