Coca leaf (121130) and poppy straw (121140) are Schedule II controlled substances under US law. Importation requires a DEA import permit in addition to any FDA requirements. These shipments face strict quota and documentation controls that go well beyond standard customs clearance.

Heading 1211 covers the raw or simply dried plant material—roots, bark, leaves, seeds—in their natural form. Once the active constituents are extracted to produce a sap, tincture, or concentrated extract, the product typically moves to heading 1302. The degree of processing is the key classification boundary.
