No. Dried mushrooms—where drying is the preservation method—generally classify under the heading for dried vegetables rather than under 2003. Heading 2003 covers mushrooms and truffles prepared or preserved by methods such as canning, brining (without acetic acid), or packing in oil, not simple desiccation.

Preserved truffles packed in oil, brine, or similar media (other than vinegar or acetic acid) fall under 200390, the non-Agaricus subheading. Their high unit value often draws additional scrutiny on valuation and country-of-origin documentation, particularly for European-origin products.
