What the trade commonly reports

What the trade commonly reports
Point of comparison	Guangxi cassia (our supply)	Vietnamese cinnamon (not our supply)
Botanical species	Cinnamomum aromaticum (syn. C. cassia), grown in Guangxi under a protected geographical indication.	Often Cinnamomum loureiroi, a related but distinct species; commonly labelled “Vietnamese cinnamon” or “Saigon cinnamon” in trade.
Common trade name	Chinese cassia, Guangxi cassia.	Vietnamese cinnamon, Saigon cinnamon; sometimes marketed simply as “cassia”.
Aroma and oil content	Warm, sweet-spicy; volatile oil content confirmed by lot test.	Often reported in the trade as higher in volatile oil and more pungent; not something we have tested ourselves.
Available from Yang Squared	Yes — 11 forms, from bark and rolls to pressed bundles and powder.	No. If a specification calls for Vietnamese cinnamon specifically, we cannot supply it.
