About heading 0510

Ambergris, castoreum, civet and musk; cantharides; bile, whether or not dried; glands and other animal products used in the preparation of pharmaceutical products, fresh, chilled, frozen or otherwise provisionally preserved

Heading 0510 covers a small set of animal-derived raw materials: the perfume fixatives ambergris, castoreum, civet and musk, plus cantharides, bile, glands and other animal products used to make pharmaceutical products. The heading is split into one line for the four named perfume materials at 5.1% and three residual lines for pancreas glands, bile and other secretions, and cantharides and other glands or organs, all duty free. Preservation state (fresh, chilled, frozen, dried or otherwise provisionally preserved) does not move the goods out of the heading.
