Last updated: April 2026 dataConiferous roundwood that has been surface-treated with paint, stain, creosote, or other preservatives occupies a distinct classification from untreated logs, and the US schedule breaks it into five 10-digit lines covering telephone/telegraph/electric power poles (4403110020), general poles/piles/posts treated with creosote or similar (4403110030), fence posts (4403110040), other poles/piles/posts (4403110050), and residual treated coniferous wood in the rough (4403110060). Canada is the dominant supplier, reflecting its integrated North American softwood industry, with Chile a secondary source. Importers should verify that the specific preservative chemistry (creosote vs. other) is correctly identified, as it determines the applicable 10-digit line and may also trigger EPA pesticide registration requirements for certain wood preservatives.

The distinction turns on end-use designation and preservative type. Line 4403110020 is reserved for telephone, telegraph, and electric power poles. Lines 4403110030 and 4403110040 cover poles/piles/posts and fence posts treated specifically with paint, stain, or creosote-type preservatives, while 4403110050 captures those treated with other preservatives. Accurate classification requires both the physical form and the specific treatment chemistry to be documented.
Creosote is a registered pesticide under FIFRA, and EPA regulates its use as a wood preservative. Importers of creosote-treated poles should confirm that the treatment was applied in compliance with applicable EPA registrations and that the product is intended for an approved use category (e.g., utility poles), as consumer-use restrictions apply to certain creosote-treated articles.
