Import Tips & Compliance
• Include NIST-traceable purity analysis; semiconductor importers often need ITAR/EAR export controls
• Declare exact purity to avoid reclassification; use proper NAICS for statistical reporting
• Avoid bulk mixtures, as they shift to 2804.90, altering duty and qualification for free trade agreements
