HS Code for Screw jack

Screw jacks are classified under HS code 8425.49. This classification is determined by the General Rules of Interpretation (GRI), specifically GRI 1, which directs classification according to the terms of the headings. Heading 8425 covers pulley tackle and hoists other than skip hoists; winches and capstans; and jacks. Within this heading, the structure differentiates between hydraulic systems and mechanical systems. A screw jack operates on the principle of a lead screw, converting rotational motion into linear motion to lift heavy loads. Because it does not utilize a liquid medium under pressure to transmit power, it is excluded from subheading 8425.42, which is reserved for hydraulic jacks. Furthermore, it is not a built-in jacking system of a kind used in garages, which would fall under 8425.41. Consequently, as a mechanical jack used for raising vehicles or other heavy objects, it is correctly placed under the residual subheading 8425.49. This code applies to both manual hand-cranked jacks and those powered by an integrated electric motor, as the mechanical screw remains the primary lifting component.

Common Misclassification

Screw jacks are frequently confused with hydraulic jacks under HS code 8425.42. The distinction lies entirely in the mechanism of action; hydraulic jacks use fluid pressure, while screw jacks use mechanical threads. Another common error is classifying them under 8479.89 as general mechanical appliances. However, because heading 8425 specifically describes "jacks," it takes precedence over the more general machinery heading 8479 according to the principle of specificity.

FAQ

What is the HS code for screw jack?

The HS code for a mechanical screw jack is 8425.49, which covers jacks other than hydraulic or garage-type systems.

Can a motorized screw jack be classified here?

Yes, even if the screw jack is driven by an electric motor, it remains classified under 8425.49 because the lifting is performed by the screw mechanism rather than a hydraulic piston.
