Import Tips
• Label with exact thermal resistance specs and semiconductor application to confirm metallurgical classification
• Avoid bulk packaging misclassification by specifying 'for float zone casting machines' in commercial invoice
• Check for anti-dumping duties on refractory liners from certain origins
