HS Code for Hot isostatic press

The hot isostatic press (HIP) is classified under HS code 8514.11. This classification is found in Chapter 85, which covers electrical machinery and equipment. While the name includes the word "press," the functional nature of the device is an industrial electric furnace. Heading 8514 covers industrial or laboratory electric furnaces and ovens. Subheading 8514.11 was specifically created to accommodate hot isostatic presses, which utilize high pressure and high temperature simultaneously to densify materials. The classification is determined by the fact that the primary mechanism for the material transformation is the controlled application of heat via electrical resistance within a high-pressure vessel. The isostatic pressure is usually applied via an inert gas like argon. Because the heating element is the core component of the system's operation, the Harmonized System treats it as a furnace rather than a mechanical press. This distinction is vital for customs compliance, as it moves the product from the machinery chapter (84) to the electrical chapter (85).

Products Included

• Industrial hot isostatic pressing units
• Laboratory-scale HIP furnaces
• HIP systems for metal powder consolidation
• Ceramic sintering hot isostatic presses
• Diffusion bonding HIP equipment

Common Misclassification

The most common misclassification for a hot isostatic press is HS code 8462.90 (or other subheadings of 8462) due to the use of the term "press." However, 8462 is for machine-tools that mechanically deform metal, whereas a HIP uses gas pressure and heat. Another common error is HS code 8419.89, which covers general heating equipment. Since 8514.11 specifically names "hot isostatic presses," it must be used according to GRI 1.

FAQ

What is the HS code for hot isostatic press?

The specific HS code for a hot isostatic press is 8514.11.

Why is it not in Chapter 84 with other presses?

It is classified in Chapter 85 because its primary function is that of an electric furnace, using heat and gas pressure rather than mechanical force to shape or densify the material.
