No. Heading 0903 covers maté whether or not roasted, so both green (unroasted) and roasted yerba maté fall under subheading 090300. Unlike coffee, where roasting creates a separate subheading, the maté heading makes no distinction based on roast level.

Maté has its own dedicated heading (0903) precisely because it is neither a Camellia sinensis tea (heading 0902) nor a general herbal infusion. Classification is based on the botanical source: only products derived from Ilex paraguariensis belong in 0903. Blended products containing maté mixed with other botanicals may require analysis of the essential character to determine the correct heading.
