Sawdust, Wood Waste & Scrap (Agglomerated, Other Than Pellets)

Artificial fire logs are specifically composed of wax combined with sawdust or wood residues, molded into a log shape for consumer use in fireplaces. Other agglomerated sawdust products (such as industrial fuel blocks) that do not contain wax as a binding agent would be classified under the appropriate NESOI or specific agglomerated line rather than 4401392000. Composition documentation from the manufacturer is the key supporting evidence.

Heading 440131 covers wood pellets specifically, and 440132 covers wood briquettes. Heading 440139 captures all other agglomerated forms of sawdust and wood waste — including agglomerated logs and other shapes — that do not meet the specific physical definitions of pellets or briquettes. When a product's form is ambiguous, importers should obtain a binding ruling from CBP to avoid misclassification.
