- Under ISO 4730, the only species officially permitted for "tea tree oil" is Melaleuca alternifolia — all others (e.g. M. linariifolia, M. dissitiflora) are classified differently
- The oil is defined as "Tea tree oil [Melaleuca alternifolia (Maiden & Betche) Cheel]" in ISO 4730, the world benchmark for this oil
- Chinese planting (Guangxi, Yunnan) now supplies a large share of global tea tree oil, with quality aligned to ISO 4730

- Do not confuse with "ti-tree" (Cordyline) or melaleuca species used for other purposes
