4705.00.00.00/Chemi-Thermomechanical Pulp (CTMP)/China

Chemi-Thermomechanical Pulp (CTMP) from China

Chemi-thermomechanical pulp (CTMP) is produced by treating wood chips with chemicals like sodium sulfite before mechanical refining under steam pressure, resulting in high-yield pulp with good strength properties. It falls under HTS 4705.00.00.00 as it combines chemical impregnation and mechanical processing to break down wood fibers. This pulp is widely used in newsprint and tissue production.

Import Tips

• Verify pulp yield and processing method via mill certificates to confirm classification under 4705, avoiding misclassification as pure mechanical pulp

• Ensure documentation includes chemical treatment details (e.g

• sulfite or peroxide) and brightness levels for customs valuation

• Check for moisture content compliance (typically 10-50%) as it affects duty assessment; common pitfall is inadequate lab testing
