What decides the code
An extension cord with plugs is an insulated electric conductor fitted with connectors, classified under heading 8544 in subheading 8544.42.90.10.
- Fitted with connectors: the plugs at each end place the cord in subheading 8544.42, which covers conductors fitted with connectors.
- Voltage not exceeding 1,000 V: the cord falls in the 8544.42 group for conductors at or below that voltage.
- Meets the definition in statistical note 7 to the chapter: the cord takes the extension cord statistical line 8544.42.90.10.
Common mistakes
- Classifying under 8544.49: that subheading covers conductors not fitted with connectors, and a cord with plugs is fitted.
- Classifying under 8536 as a plug or connector: the cord is an insulated conductor assembly, and the plugs are fittings on it, not the article itself.
- Classifying under 8544.42.90.90 as other: the cord meets statistical note 7, so the extension cord line 8544.42.90.10 applies.
