Import Tips
• Include engineering drawings showing marine-specific features like corrosion-resistant coatings to support classification
• Ensure supplier declarations specify 'sole use with marine propulsion engines' to prevent misclassification
• Watch for anti-dumping duties on certain aluminum imports; check Commerce Department scopes
