Steel Plug Cock Valve for Semiconductor Wafer Processing from China
A hand-operated steel plug type valve used in high-purity gas lines for semiconductor wafer manufacturing equipment, such as crystal growers. It falls under HTS 8481.80.3065 as a hand-operated plug type valve of steel for precise flow control in cleanroom environments. The plug design ensures tight shutoff and minimal leakage critical for processing silicon boules.

Import Tips
• Verify valve meets semiconductor industry purity standards (e.g
• SEMI F19) with material certificates for import compliance
• Include end-use documentation proving use in wafer manufacturing to avoid reclassification during customs review
