Import Tips

Verify the spring is specifically for watch movements (under 12mm thick/50mm wide per chapter note 3) to avoid reclassification to chapter 85

Include technical specs and end-use certification proving clock/watch exclusivity, as dual-use parts may shift to other headings

Watch for anti-dumping duties on precision springs from certain origins; declare material composition accurately
