HS Code for HIP furnace

Hot Isostatic Presses (HIP) are classified under HS code 8514.11, which covers industrial or laboratory electric resistance-heated furnaces and ovens. The classification is precise because HIP equipment utilizes resistance heating elements to maintain high temperatures while simultaneously applying high isostatic gas pressure (usually argon) to materials. Under the Harmonized System, heading 8514 is dedicated to industrial electric furnaces. Subheading 8514.11 was specifically created to include hot isostatic presses, recognizing their unique dual function of thermal treatment and pressure application within a resistance-heated environment. These machines are essential for densifying castings, consolidating powders, and diffusion bonding, and their classification is driven by the primary heating method (resistance) and their specific industrial application as a press-furnace hybrid.

Products Included

• Industrial hot isostatic pressing units
• Laboratory-scale HIP furnaces
• Resistance-heated pressure vessels for material densification
• Sinter-HIP furnaces (resistance heated)
• HIP units for additive manufacturing post-processing

Common Misclassification

HIP furnaces are often misclassified under 8479.89, which is a general category for machines and mechanical appliances having individual functions. However, because the primary function involves industrial heating, heading 8514 takes precedence. Another common error is 8514.20, which covers furnaces functioning by induction or dielectric loss. If the HIP unit uses resistance heating, 8514.11 is mandatory. Furthermore, standard isostatic presses that operate at room temperature (Cold Isostatic Presses) are classified under 8479.81 and should not be confused with the heated HIP units in 8514.11.

FAQ

What is the HS code for HIP furnace?

The HS code for a Hot Isostatic Press (HIP) furnace is 8514.11, covering resistance-heated industrial electric furnaces.

Does this code include cold isostatic presses?

No, cold isostatic presses (CIP) do not involve the heating elements required for classification under 8514 and are typically classified under heading 8479.
