Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If web classified separately as fiberboard
OSB panels imported unattached to flanges classify as medium density fiberboard under heading 4411, reassembling creates the engineered I-beam.
If multi-layer assembled beams
Beams constructed from multiple solid wood layers rather than distinct I-web/flange design fall under other assembled wood products.
Not sure which classification is right?
The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Submit manufacturer performance data sheets; verify web shear values meet US standards; avoid bundling with metal hangers that trigger different classifications
