On this page

What Are Section 232 Tariffs?

Section 232 of the Trade Expansion Act of 1962 allows tariffs on imports deemed a threat to national security. In 2018, the Commerce Department determined steel and aluminum imports threatened national security, triggering tariffs that remain in effect today.

Current Rates

  • Steel: 25% ad valorem duty
  • Aluminum: 10% ad valorem duty
  • Applied in addition to regular Column 1 duties
  • Stacks with Section 301 duties for Chinese origin

Country-Specific Arrangements

Tariff-Rate Quotas (TRQ)

  • EU: Historical volume duty-free, above-quota at 25%
  • UK: Quota system in place
  • Japan: Negotiated TRQ for specific products

Exemptions and Modifications

  • Canada/Mexico: Exempt under USMCA melt-and-pour requirements
  • Australia: Full exemption
  • South Korea: Absolute quota instead of tariff

Product Scope

Steel (HTS Chapters 72-73)

  • Flat products: sheets, plates, strips
  • Long products: bars, rods, wire
  • Tubular products: pipes, tubes
  • Stainless and alloy steel included

Aluminum (HTS Chapter 76)

  • Unwrought aluminum
  • Flat rolled products
  • Bars, rods, profiles
  • Foil and wire

Product Exclusion Process

Importers can request exclusions for specific products through the Bureau of Industry and Security (BIS) portal:

  1. Demonstrate product not produced in US in sufficient quantity/quality
  2. Submit through 232 Exclusions Portal
  3. Objection period for US producers
  4. Decision typically within 90-120 days
  5. Approved exclusions last 1 year

Melt-and-Pour Requirement

USMCA exemption requires steel to be melted AND poured in North America. Aluminum must be smelted AND cast. This prevents transshipment through Canada or Mexico to avoid tariffs.

Compliance Best Practices

  • Maintain mill test certificates for country of origin
  • Verify melt-and-pour documentation for USMCA claims
  • Monitor TRQ fill rates for EU/UK imports
  • File exclusion requests early for unique products
  • Track quarterly quota updates from Commerce

Impact on Downstream Industries

Section 232 tariffs affect automotive, construction, machinery, and packaging sectors. Importers of finished goods containing steel/aluminum components should evaluate total landed cost impact. Specialty alloys and certain grades may qualify for exclusions.
