ISO4730 and AS 2782-2009 Standards

The chemical composition of tea tree oil is defined by international standard ISO 4730 (2004) and the identical Australian standard AS 2782-2009 ("Oil of Melaleuca, Terpinen-4-ol type"), which specifies levels of 15 of the more than 100 components in pure Australian tea tree oil. Any batch of oil sold by an ATTIA member must be accompanied by an independently tested certificate of analysis demonstrating conformance to these standards. ATTIA also recommends that the country of origin is clearly declared when purchasing tea tree oil from any supplier.

A summary of the standard:

AS 2782 – 2009 Oil of Melaleuca, terpen-4-ol type (Tea Tree Oil)

Essential oil obtained by steam distillation of the foliage and terminal branchlets of Melaleuca alternifolia (Maiden et Betche) Cheel, Melaleuca linariifolia Smith, and Melaleuca dissitiflora F. Mueller, as well as other species of Melaleuca provided that the oil obtained conforms to the requirements given in this International Standard.
