Bay oil is not a complete technical specification. Leaf essential oil and fixed oil from the fruit are different products; do not order one as a substitute for the other.
Why name the method?
A comparative study of Laurus nobilis examines hydrodistillation and steam distillation separately. Its processing conditions do not establish our facility capacity or the characteristics of a quoted batch. Ask the supplier to identify the actual method.

How should yield and composition be assessed?
An oil percentage or constituent proportion should be accompanied by method and units in a batch report. Check the sampled material and that the report’s batch number matches the shipment. Do not use an isolated online average as a purchase acceptance limit.
What belongs in the enquiry?
State botanical name, plant part, oil type, application, quantity and packaging. Identify required analyses and safety data sheets beforehand. Oil availability, lead time and technical suitability need written confirmation; the leaf catalogue is not an oil-stock commitment.
