Western importers of hardware and electronic components now face a fundamentally restructured regulatory environment. This shift has materially altered landed-cost calculations for global OEMs.
Section 232 Forces Immediate Full-Value Tariff Reclassification
On April 2, 2026, the White House issued a presidential proclamation that overturned the prior content-based valuation methodology under Section 232 tariffs for steel, aluminum, copper, and their derivatives. Effective April 6, 2026, authorities replaced the old approach—which calculated duties according to the actual embedded metal weight or value—with a classification-based full entered-value approach.
Under the new rules, if a product or subcomponent’s HTS code falls within the covered annexes, the applicable tariffs—ranging from 25% to 50%—apply directly to the entire customs declared value of the imported good. Metal content percentage receives no offset. Hardware manufacturers importing items with metal enclosures, submodules, or assembled electronic structures must now re-audit HTS classifications. Tariff exposure has risen sharply for many lines.
A May 27, 2026, analysis by Foley & Lardner captured the compliance implications of this overhaul for multinationals.
Section 301 Overlays Compound Electronic Component Pain Points
Section 301 tariffs on Chinese-origin semiconductors, covering wafer fabrication and assembly/test stages, remain locked at 50%. This layer continues to pressure industrial electronics supply chains.
The Institute for Supply Management (ISM) released its May 2026 Manufacturing PMI report showing the index at 54%, holding above the expansion threshold. The Computer & Electronic Products sector stood out as a leading growth category amid persistent price pressures.
Printed circuit board assemblies (PCBA), drive control boards, and advanced sensor modules assembled in China now carry combined tariff burdens frequently exceeding 35%. These rates incorporate base MFN duties, Section 301 levies, and potential Section 232 overlays where metal content triggers classification. Margin compression has become acute for many electronics producers.
Tariff Impact Summary
| Category | Key Change | Tariff Rate | Scope | Effective Date |
|---|---|---|---|---|
| Section 232 Steel/Aluminum/Copper Articles & Certain Derivatives (Annex I-A) | Full entered value; no metal content offset | 50% ad valorem (reduced for qualifying UK or US-origin metal) | Covered HTS classifications including derivatives | April 6, 2026 |
| Certain Derivatives (Annex I-B) | Full entered value | 25% ad valorem (reduced options available) | Steel/aluminum/copper derivative products | April 6, 2026 |
| Chinese Semiconductors (Section 301) | Existing forced technology transfer duties | 50% | Wafer, assembly, test stages | Ongoing |
| Computer & Electronic Products (ISM Prices Index) | Sustained price increases reported | N/A (input cost pressure) | Manufacturing PMI sub-index | May 2026 reading: Prices ~82.1% |

Compliance Teams Must Map Both Risks and Targeted Exemptions
OEMs face immediate requirements to map new HTS exposures, recalibrate supplier quotes, and model updated landed costs. While de minimis exemptions for low metal content (<15% in certain derivatives) provide limited relief, classification diligence remains non-negotiable.
Supply chain teams should pay particular attention to one under-discussed carve-out: Annex I-B explicitly exempts motorcycle parts classifiable under HTSUS Chapters 84, 85, and 87 when imported exclusively for use in U.S. motorcycle manufacturing. Electronics and automotive suppliers with overlapping component strategies can leverage this provision through precise origin engineering and end-use documentation.
Compliance officers should consult current annexes published with the April 2026 proclamation and monitor subsequent adjustments, including the June 2026 refinements. Proactive reclassification, targeted exemption claims, and origin engineering remain the primary levers to mitigate exposure in this tightened regime.
