Chemi-Thermomechanical Pulp (CTMP) Softwood from Germany
Chemi-Thermomechanical Pulp (CTMP) from softwood involves a mild sodium sulfite pretreatment before thermomechanical refining, which improves brightness and strength while preserving most lignin. The chemical treatment is minimal and does not dissolve significant wood components, keeping the yield high. This pulp is classified as mechanical wood pulp under 4701.00.00.

Import Tips
• Document the sodium sulfite charge (typically under 5% on wood) to prove the chemical treatment is mild and non-dissolving
• The CBSA may test the pulp's lignin content or yield; be prepared to provide mill process data
• Verify that the pulp does not meet the dissolving grade criteria of heading 47.02
