Import Tips
• Confirm the copper foil thickness is 0.15 mm or less, excluding the BT resin backing, to meet the tariff item definition
• Keep technical documentation showing the refined copper composition (at least 99.85% copper) for CBSA verification
• If the laminate is used in finished semiconductor packages, confirm whether the finished article classification applies instead
