Import Tips

• Obtain end-use certification proving semiconductor manufacturing application to avoid reclassification to general machinery

• Include detailed technical specs showing gas turbine integration and wafer boule production role in commercial invoice

• Verify compliance with export controls (EAR/ITAR) as crystal growers often contain controlled precision components
