SEO Query about Product Categories

Hello WPMU Dev MarketPress support,

When defining a Post in WordPress the advice I am always given is only assign it to one Category and as many Tags as you like, as assigning a Post to more than one Category will be seen as duplicate content by the SEO engines.

Does the same hold true for Product Categories within MarketPress?

Can a Product be assigned to more than one Product Category without it being seen as duplicate content by the SEO engines?

Do appreciate that you are not in control of how SEO engines view content so not able to provide a definitive answer, but any chance on providing some general guidance on this.

Kind regards,
