CFR Title 19: Customs Duties
Title 19 of the Code of Federal Regulations covers Customs Duties. This title contains the codified rules and regulations issued by federal agencies under their statutory authority. The Electronic Code of Federal Regulations (eCFR) shows the latest issue date as 2026-08-12 and the content as up-to-date as of 2026-08-20.
What Title 19 Regulates
Customs Duties is one of the 50 broad subject matter titles that make up the CFR. Agencies with responsibilities in this area publish proposed and final rules in the Federal Register. Once finalized, those rules are organized by title and part in the CFR. Title 19 may include definitions, compliance requirements, reporting obligations, penalties, and procedures that affect individuals, businesses, and other organizations.
Because agencies update rules frequently, the version of a regulation you read today may be different tomorrow. Always verify the current text through the official eCFR or Federal Register before relying on it for compliance, litigation, or legal advice.
What Is the CFR?
The Code of Federal Regulations (CFR) is the codification of the general and permanent rules published in the Federal Register by executive departments and agencies of the federal government. It is divided into 50 titles, each covering a broad regulatory area. Agencies propose and finalize rules in the Federal Register, and those final rules are later incorporated into the CFR. Title 19 is maintained by the agencies that have rulemaking authority in this area.
How to Cite CFR Title 19
A citation to a CFR provision typically looks like 19 C.F.R. § ___, where the part and section numbers follow the title. For example, a reference to part 100 of Title 19 would be cited as 19 C.F.R. § 100.___. Always check the current edition when citing a regulation.
