U.S. exports of non-impregnated nonconiferous railway & tramway sleepers (ties) (HS 440612) totaled $1.0M in August 2026, exported to 2 countries.
Last updated: August 2026 dataHardwood railway and tramway sleepers that have not been impregnated with preservatives are classified under a single 10-digit line (4406120000), covering species such as oak, azobé, and other dense hardwoods traditionally valued for their natural durability in track applications. Canada and Gabon are the two recorded US suppliers, reflecting both North American hardwood production and Central African tropical timber exports. Gabon's presence signals that tropical hardwood species — which may be subject to CITES review or Lacey Act documentation requirements — are a meaningful part of this trade flow. Importers must be prepared to provide species identification and chain-of-custody documentation to satisfy Lacey Act due-care obligations.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The Lacey Act requires importers to file a Plant and Plant Product Declaration (PPQ Form 505) for covered wood products, identifying the scientific name of the species, country of harvest, and quantity. For tropical hardwoods from Gabon, accurate species identification is essential, and importers should obtain harvest legality documentation from their supplier to satisfy due-care requirements.
The HS structure separates sleepers by both wood type (coniferous vs. nonconiferous) and treatment status (impregnated vs. not), because preservative treatment significantly changes the product's durability, end use, and sometimes its tariff treatment. Importers should verify the treatment status with mill documentation, as misclassification between impregnated and non-impregnated lines can result in duty discrepancies and CBP penalties.
