Import Tips
• Include process diagrams showing zone melting technique to substantiate semiconductor-specific classification
• Ensure labeling specifies 'for silicon/gallium arsenide monocrystalline growth' to prevent bulk machinery misclassification
• Watch for reclassification if equipment lacks RF heating coil specific to float zone method
