Sun Luck has a line of Chinese products, such as Hoisin Sauce and Black
Bean Sauce.  I normally wouldn't ask until I've contacted the company.
Being that it's Sunday, I don't think they'll be there.

Is anyone familiar with their gluten-free status, in particular their
Black Bean Garlic Sauce?  If not, can anyone recommend a black bean
sauce (GF)?  Thank you for your help.  Sidona
