Derricks & Cranes (NES), Not Self-Propelled

When a crane is permanently mounted on a truck chassis and the crane function is primary, the combined unit is generally classified as a crane rather than a motor vehicle. However, if the truck is imported separately from the crane superstructure, each component is classified independently. The degree of integration and which function predominates are the key factors; a licensed customs broker should review the specific configuration.

Oil-field drilling derricks are typically stationary, non-self-propelled structures used to support drill strings rather than to transport loads horizontally — a function distinct from overhead travelling cranes or portal jib cranes. Because no more specific SITC heading captures them, they default to 74439. Importers should document the derrick's function and structural design clearly in the entry to avoid reclassification disputes.
