SITCSection 6
U.S. imports of copper foil (not over 0.15 mm thick) (SITC 68261) totaled $41.2M in April 2026, traded with 27 countries.
Importers of Copper Foil (Not Over 0.15 mm Thick) paid $18.3M in duties in April 2026 — an effective duty rate of 45% on $40.8M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataElectrodeposited and rolled copper foil at or below 0.15 mm thickness is a foundational material for printed circuit boards (PCBs), lithium-ion battery current collectors, and electromagnetic shielding — making it a strategically significant input for electronics and electric vehicle manufacturing. The product may be bare, printed, or backed with paper, polymer, or other materials, and the backing does not change the classification as long as the copper layer itself does not exceed the thickness threshold. Section 301 tariffs have applied to certain electronics-related copper foil imports from China, creating meaningful cost and sourcing considerations for PCB and battery manufacturers. Surface roughness (Rz value) and peel strength are critical quality parameters for PCB-grade foil that should be specified in purchase contracts.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
No — the heading explicitly covers foil whether or not backed with paper, polymer, or other materials, provided the copper layer itself does not exceed 0.15 mm. The nature of the backing may, however, affect other regulatory requirements (e.g., chemical content declarations for certain polymer backings) and should be documented on the commercial invoice.
PCB-grade electrodeposited foil is characterized by controlled surface roughness (Rz on the matte side), tensile strength, elongation, and peel strength to the laminate substrate. IPC-4562 is the widely referenced industry standard in the US market. Importers supplying PCB fabricators should ensure mill certifications include these parameters, as substitution of a lower-grade foil can cause lamination defects and customer rejections.
