Dried Wood Ear Mushrooms (Auricularia spp.)

The distinction is botanical: Auricularia species (wood ears, black fungus) have a characteristic ear-shaped, gelatinous-when-rehydrated form and are classified under 0712320000, while Tremella species (snow fungus, white jelly fungus) fall under 0712330000. Importers should request species-level identification from suppliers — ideally with a phytosanitary or botanical certificate — because the two genera can appear visually similar in dried form and misclassification is a known audit risk.

Beyond standard FDA Prior Notice and commercial invoice requirements, importers sourcing from China should maintain records supporting the Section 301 tariff classification, including supplier certificates confirming species identity and country of origin. If product is transshipped through Vietnam or other intermediary countries, CBP may scrutinize origin claims closely. A licensed customs broker can advise on origin documentation standards and current Section 301 applicability.
