Title 19 › CHAPTER 4 — TARIFF ACT OF 1930 › SUBTITLE III — ADMINISTRATIVE PROVISIONS › Part VI — Miscellaneous Provisions › § 1644a
The Secretary of the Treasury can name which U.S. airports are official ports of entry for civil aircraft coming from other countries. The Secretary can assign Customs officers to those ports, give other federal officers Customs duties if their bosses agree, and make rules that apply Customs, public health, immigration, and some ship-entry rules to planes when needed. If someone breaks those rules or related health or Customs laws that now apply to aircraft, they can be fined $5,000 for each violation, and the plane can be seized or forfeited. The Secretary (and for some immigration rules, the Attorney General) can reduce or cancel those fines. If a controlled drug covered by section 1584 is found on or unloaded from the plane, the owner or person in command must pay the penalties in section 1584 unless they prove they did not know and used the highest care to prevent it. If the owner, operator, or commander breaks the rule, the plane can be held by a lien. The Secretary of Agriculture can make plant and animal quarantine laws apply to civil air travel, and violators face the penalties those laws call for. Decisions to reduce or cancel penalties are final, and the Secretary must tell the Attorney General if a forfeiture court case is happening during a penalty review. A plane with a lien can be quickly seized, reported to the Attorney General, and either held until legal action is taken or released if the fine is paid, a court seizes it, the Attorney General declines action, or a bond is posted. Penalties can be collected by suing the person, suing the plane, or both, using admiralty-style rules; a jury may be requested if the amount in dispute is more than $20. Agencies may be given money to rent space at a public airport (see 49 U.S.C. 47102) for inspections or related work, but they must consult the Secretary of Transportation first. Definitions used follow 49 U.S.C. 40102(a).
