Thermomechanical Pulp (TMP) from Spruce from United States
Thermomechanical Pulp (TMP) from spruce is produced by steaming wood chips at high temperature followed by mechanical defibration in refiners, preserving most lignin for strength and yield. This pulp is ideal for magazine paper and board due to its high bulk and print quality. The process is mechanical, with no chemical pulping, so it falls under 4701.00.00.

Import Tips
• Document the steaming temperature and time to show the process is thermal-mechanical, not chemical
• The CBSA may verify that no chemicals were added; keep a list of additives (if any) to prove they are non-dissolving
• Ensure the yield exceeds 90% to maintain mechanical pulp classification
