Import Tips
• Obtain mill certificates verifying tungsten content (typically 65-85%) and compliance with Chapter 72 purity standards to avoid reclassification
• Ensure proper packaging to prevent oxidation; declare exact chemical composition on entry documents as ferroalloys are subject to precise alloy definitions
