Smoot-Hawley Tariff Act (Tariff Act of 1930)

Its rate schedules were replaced long ago, but its sections still govern imports: Section 304 requires country of origin marking, Section 307 bans goods made with forced labor, Section 321 provides the de minimis authority, Section 337 lets the ITC exclude infringing goods, Section 484 requires entry by the importer of record and Section 592 penalizes false statements. Section 338 allows duties of up to 50 percent on countries that discriminate against US commerce.

Most day-to-day US import obligations a fulfillment operator faces trace back to the Tariff Act of 1930. A 3PL receiving a container must make sure goods are marked with their origin under Section 304, expect that suspected forced-labor goods can be detained under Section 307, now enforced with the UFLPA, and keep entry data accurate to avoid Section 592 penalties. The original 1930 rate increases are also the standard historical example of a retaliatory tariff spiral, often cited in current tariff debates.
