Pulpwood and Woodpulp

USDA APHIS phytosanitary requirements apply primarily to unprocessed pulpwood logs and raw wood, which may require import permits and pest-treatment certification. Processed woodpulp that has undergone chemical or mechanical pulping is generally considered a manufactured product and faces fewer phytosanitary restrictions, though importers should confirm the applicable APHIS regulations for their specific material.

Woodpulp is broadly divided by pulping process — chemical pulps (kraft and sulfite) versus mechanical and semi-chemical pulps — and further by bleaching status (bleached, semi-bleached, unbleached). These distinctions affect both the applicable HTS subheading and the product's suitability for specific paper grades, making accurate grade identification essential for correct classification and contract specification.
