4701.00.00.00/Northern Bleached Softwood Kraft Mechanical Pulp (NBSKMP)/Mexico

Northern Bleached Softwood Kraft Mechanical Pulp (NBSKMP) from Mexico

NBSKMP is a high-yield mechanical pulp produced from softwood chips using a combination of mechanical grinding and mild chemical treatment, resulting in fibers with significant lignin content. It is primarily used in newsprint and tissue paper production due to its bulk and opacity. Classified under HTS 4701.00.00.00 as mechanical woodpulp, distinct from chemical pulps which remove most lignin.

Import Tips

• Verify pulp yield (85-98%) and lignin content (>20%) through lab testing to confirm mechanical classification vs. chemical pulp

• Include mill certificates specifying production method (e.g

• refiner mechanical pulping) and wood species for customs compliance

• Avoid misclassification as chemical pulp by ensuring documentation excludes low lignin or high alpha-cellulose specs
