Look for an essential-oil batch document using the manufacturer, full product name and the identifier on your particular bottle. A brand presentation or report for another batch does not replace that match. Save the packaging details before searching an official source.
Copy the package identifiers first
Photograph the code so that its letters and numbers remain legible. Keep the product name, manufacturer and quantity. If the box and bottle have several codes, record them separately instead of guessing which one identifies the batch.
Distinguish a batch identifier from a product barcode. Ask the seller which code connects your bottle to its documentation when the marking is unclear. The same information supports both a search and a question to the manufacturer.

A doTERRA lookup example
The official Source to You page offers GC/MS report lookup by Quality ID. It describes an identifier on the bottom of doTERRA single-essential-oil bottles purchased after May 2016. This is that service's route, rather than a rule for every brand.
Open the official page, find the Quality ID field and enter the code from your own bottle. If a report is returned, compare its identifier and product description with the package. We checked the public lookup page for this guide. We did not submit a made-up code or obtain a report for an unknown batch.
Check a returned document
| Check | Question |
|---|---|
| Identity | Does the identifier match your bottle? |
| Product | Do the name and described material match? |
| File origin | Did it come from an official source or receive manufacturer confirmation? |
| Scope | What was tested, and which explanations accompany the result? |
A graph with peaks does not let an untrained reader certify authenticity, safety or a treatment effect. Ask the manufacturer or a suitably qualified specialist to explain unclear conclusions. Keep the original file with its source address and retrieval date.
If you cannot find a report
Source to You says that its GC/MS report lookup does not support proprietary blends. An empty result for an unsupported category alone does not prove a counterfeit. Ask the manufacturer which documents are available for your product and how they connect to its batch.
Explore the oil's name in eoASSIST. Keep batch documentation separately from the general reference entry. The label guide lists the package fields worth recording.
