Bleached Chemi-Thermomechanical Pulp (BCTMP)
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.

More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the pulp is bleached and primarily chemical, with minimal mechanical processing
Bleached chemical wood pulp (soda or sulphate) falls under heading 47.03, not the combined process pulp of 4705.
If the pulp is bleached chemical sulphite pulp
Bleached sulphite chemical pulp is classified under heading 47.04, distinct from combined mechanical-chemical pulp.

Import Tips & Compliance
• 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
