U.S. exports of levorphanol and its salts (HS 293341) totaled $35K in June 2026, traded with 1 country.
Levorphanol is a Schedule II opioid analgesic used in pain management, and its INN designation signals that imports are subject to both FDA drug admissibility review and DEA import authorization as a controlled substance. All US imports enter under the single tariff line 2933410000. India and Denmark are the documented leading suppliers, reflecting India's active pharmaceutical ingredient manufacturing capacity and Denmark's established pharmaceutical export sector. Classification is straightforward given the dedicated heading, but regulatory compliance — including DEA quota allocation — is the primary complexity for importers.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yes. As a Schedule II controlled substance, levorphanol is subject to DEA import quotas and requires an advance import permit. FDA admissibility review applies separately to ensure the active pharmaceutical ingredient meets applicable standards. Importers should engage both agencies well in advance of shipment. Consult a licensed customs broker or regulatory counsel familiar with controlled substance imports.
Levorphanol has its own dedicated HS6 heading (293341) and a single 10-digit line (2933410000), unlike many opioid-related compounds that fall into broader NESOI categories. This specificity reduces misclassification risk but means any shipment of levorphanol or its salts — regardless of salt form — must be declared under that single line.
