If outer plies are not both coniferous

If not considered 'plywood' but builder's joinery

Import Tips & Compliance
• Verify both outer plies are coniferous species via mill certificates; misclassification to non-coniferous headings is common
• Ensure formaldehyde emission compliance (EPA TSCA Title VI) with lab test reports for composite wood products
• Declare accurate glue type and layers; exterior-grade requires waterproof phenolic resin documentation
