Import Tips
• Determine whether the valves are classifiable as parts of general use under Section XV Note 2 (e.g
• taps, cocks, and valves of heading 84.81)
• If they are complete valves, they may be classified under heading 84.81 rather than 8109.99.00
• Provide a detailed product description and technical drawings to support classification
• Check if the valves require any special import permits for use in chemical plants
