Import Tips

• Ensure the borings are accompanied by a certificate of analysis confirming hafnium content below 1 part per 500 parts zirconium

• Declare the goods as waste and scrap, not as articles, to avoid misclassification

• Keep records of the original source to support the low-hafnium claim
