Like I said, I'd put this Lemongrass up against the highest quality on the market. In terms of the oil being organic, there is no pesticides or non-natural fertilizers and no toxic additives. I only sell one type of Lemongrass: the highest quality.
From what I gather NDA is an Australian based producer/supplier, if I were looking for Tea Tree oil I wouldn't go anywhere else. I strongly associate Australia with a long history of Tea Tree use.
My same approach applies to lemongrass, vetiver, jasmine, juniper berry and other Indian-related essential oils. Having suffered through India's horrible transportation infrastructure, any oil that emerges from India from non-Indian producers raises suspicions. Anyone who can transport within India, or export from India on the cheap isn't likely to be who they say they are. The majority of India is still rural and the parts that aren't have begun chemical fertilizing process, so it's incredibly important to find growers off the grid who aren't entrenched in chemical practices yet.
Fair point on quantity, I have 200 ml available. All of it is for sale. Anyone with an offer can contact me via eBay messaging if they desire or leave a message here.
