Import Tips & Compliance
• Distinguish from statistical 8483.20.40 by confirming non-standard flange geometry via CAD drawings
• Include vibration and temperature ratings in paperwork, as these affect end-use declarations
• Avoid pitfall of bulk packaging declaration; retail-ready units may require consumer product labeling
