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
