Most commercially traded truffle species are not CITES-listed, but importers should confirm the species identity and verify that the product is not subject to any country-of-origin export restrictions. Standard FDA requirements apply: prior notice, facility registration, and FSMA supplier verification. For wild-harvested specialty fungi, species identification documentation from the supplier is advisable to support admissibility and classification.

Sun-dried, air-dried, and mechanically dehydrated mushrooms all fall under this heading, but the method significantly affects flavor intensity, rehydration characteristics, and market price. For example, traditionally sun-dried shiitake develop higher levels of guanylate (a flavor enhancer) than mechanically dried equivalents, commanding a premium in specialty food markets. The drying method should be specified in commercial contracts but does not change the SITC classification.
