Based on the provided HS codes, here's a breakdown of the potential classifications for "EXTENSION TUBE", along with relevant details to help you determine the most accurate categorization for your specific product.

Important Note: The correct HS code depends heavily on the material and intended use of the extension tube. The following analysis covers the options provided, but further information about your product may be needed for a definitive classification.
