Import Tips
• Include ATEX or IP65 ratings documentation for cleanroom compatibility; customs often scrutinize contamination risks in semiconductor imports
• Avoid pitfall of declaring as 'general purpose' - specify wafer fabrication end-use with equipment model references in entry docs
• Calculate duties using column 1 rates; check for temporary exclusions under USTR semiconductor equipment lists
