Import Tips
• Ensure the insulators are described as ceramic housings, not as surge arrestors, which may be classified under heading 85.35 or 85.36
• Provide mechanical and electrical specifications to support the classification
• If imported with internal components, confirm whether they are complete surge arrestors or just insulators
