Import Tips
• Verify compatibility with specific boiler models under headings 8402/8403 via technical specs to avoid misclassification
• Provide detailed engineering drawings and material certificates (e.g
• ASME-compliant steel) for valuation and origin determination
• Watch for anti-dumping duties on certain steel components; declare as 'parts of economizers' explicitly on commercial invoice
