Import Tips
• Include NIST-traceable calibration certificates to support value declaration and prevent undervaluation disputes
• Declare exact density and purity to distinguish from lead or steel counterfeits, common in scale weight imports
• Check for anti-dumping duties if sourced from non-market economies, as tungsten products face scrutiny
