CBP Outlines New Compliance for Metal Tariffs Enforcement
CBP releases new compliance rules for metal tariffs affecting legal strategies.
Why it matters: Legal teams must navigate complex tariff reporting, impacting compliance costs and client advisement.
- 50% duty on full customs value for certain metals under HTSUS 9903.82.02.
- 0% duty if metal is under 15% weight as per HTSUS 9903.82.03.
- 25% and 15% duties for UK derivatives under HTSUS 9903.82.04 and 9903.82.05.
- Copper tariffs vary by U.S. content thresholds.
The U.S. Customs and Border Protection (CBP) recently introduced updated compliance guidelines for reporting tariffs on imports like steel, aluminum, and copper. This follows a recent presidential proclamation from 2026 detailing changes in tariff structures.
Legal professionals specializing in import/export must now adapt to these measures, as failure to comply could lead to increased duties and penalties. The guidelines specify a 50% duty on the full customs value for identified metals classified under HTSUS 9903.82.02. Products that contain less than 15% of these metals by weight may qualify for a 0% duty, provided appropriate weight documentation is presented, outlined in HTSUS 9903.82.03.
The guidelines also modify duties for metal derivatives originating from the UK. Such articles will incur a 25% or 15% duty, depending on processing specifics, classified under HTSUS 9903.82.04 and 9903.82.05. Copper-related tariffs will vary according to the proportion of U.S. content, as specified in HTSUS 9903.82.06 to HTSUS 9903.82.11.
In response, law firms and corporate legal departments must diligently assess and document the country of origin for their metallic components, especially for steel and aluminum. Future updates, expected via CBP's Cargo Systems Messaging Service (CSMS), will further guide updates on copper components.

By the numbers:
- 50% duty — Full customs value for specific metals under HTSUS 9903.82.02
- 0% duty — Less than 15% of product weight for duty exemption
- 25% and 15% — Duties for UK-origin derivatives based on processing specifics
Yes, but: Importers must quickly adapt to these changes, but ongoing legal interpretations may affect final duty rates.
What's next: CBP to release further updates on copper tariffs via CSMS.
