Import Tips
• Obtain aerospace-grade certifications (e.g
• MIL specs) alongside silica purity tests for customs validation
• Declare end-use as non-structural fabric to stay in 7019, avoiding parts classifications
• Watch for anti-dumping duties on certain high-tech glass fibers from specific countries
