The United States maintains multiple layers of import duties on electrical grade glass cloth tapes, beginning with the Most Favored Nation (MFN) tariffs, which conventionally range from 2% to 5% on glass fiber and related products. In addition, Section 301 tariffs, imposed in response to trade remedy investigations, currently assess an extra 7.5% to 25% duty on imports of glass fibers and substrates from certain origins, including China. These measures are designed to counteract unfair trade practices but also alter the cost base for downstream tape manufacturers and equipment integrators relying on foreign-sourced raw materials.

Layered atop these duties are IEEPA-based tariffs targeting goods from China and Hong Kong, initially implemented at 20% in March 2025 to address national security and public health concerns linked to fentanyl precursor controls. These additional ad valorem tariffs apply broadly to all imports of Chinese origin, further amplifying landed costs and complicating procurement strategies for importers in North America and Europe.

Beyond these product-specific measures, a limited-term reciprocal tariff reduction agreement temporarily lowered certain “reciprocal” duties from 125% to 10% effective May 14, 2025. However, this reduction did not extend to Section 301 or IEEPA levies and is set to expire in August unless renegotiated. Concurrently, exclusion extensions under Section 301 granted relief for specified product lines through August 31, 2025, offering brief cost reprieve to eligible importers but creating uncertainty for long-term supply chain planning.

The cumulative impact of these overlapping tariffs has prompted manufacturers to reassess sourcing strategies, often turning to regional suppliers or relocating production closer to end markets to mitigate duty exposure.
