Import Tips
• Include GC-MS purity certificates showing minimum 99.5% tert-butanol content to prevent reclassification
• Declare exact water content (<0.3%) as aqueous solutions may require different headings per chapter notes
• Use stainless steel containers only; avoid plastic drums that could cause contamination issues during customs inspection
