Import Tips
• Include GC-MS or NMR spectra in import declarations to prove chemical identity and exclude impurities that might reclassify under 'other' 2929.90
• Comply with TSCA premanufacture notification if for commercial use; pitfalls involve failing to declare end-use which triggers export control scrutiny
• Use UN-approved packaging for Class 8 corrosives; improper venting leads to common shipment rejections
