Import Tips
• Obtain phytosanitary certificates confirming Douglas fir treatment per ISPM 15 for wood packaging materials used in shipping
• Document truss span ratings (e.g
• 40-60 ft) and wind/snow load certifications to distinguish from general carpentry
• Bundle with installation manuals to demonstrate end-use as roof trusses, preventing misclassification as flooring panels
