Bleached Chemi-Thermomechanical Pulp (BCTMP) from United States
Bleached Chemi-Thermomechanical Pulp (BCTMP) is produced by chemically treating wood chips with sodium sulfite or similar agents, followed by mechanical refining under steam pressure, and then peroxide bleaching to achieve high brightness. This combined chemical and mechanical process qualifies it as wood pulp obtained by a combination of mechanical and chemical pulping processes under tariff item 4705.00.00.

Import Tips
• Ensure the pulp's production process documentation clearly states both chemical and mechanical stages to support classification under 4705.00.00
• Verify that the pulp is not classified as dissolving grade (heading 47.02) by testing solubility if required
• Keep records of the bleaching agents used, as they may be relevant for CBSA verification
