Import Tips

Verify the foundation is non-mechanically adjustable and includes legs to confirm HTS 9403.20.0048 classification; provide assembly diagrams if needed

Ensure metal composition labeling complies with US customs rules and include country-of-melt documentation for steel products

Avoid misclassification as parts by importing complete units; check for foldable features to prevent shifting to general frames
