Monoblock pump HSN Code

Understanding Monoblock Pump HSN Codes

Monoblock pumps are widely used in residential, agricultural, and industrial settings for efficiently moving liquids, primarily water. Characterized by their compact design where the pump and motor are integrated into a single unit, these pumps are a critical piece of machinery. For businesses involved in their manufacture, distribution, or sale in India, understanding the correct Harmonized System of Nomenclature (HSN) code for monoblock pumps is essential for accurate Goods and Services Tax (GST) compliance.

The HSN system is a globally standardized method for classifying traded products, vital for streamlining customs procedures and ensuring consistent taxation. When classifying a “monoblock pump,” its function as a liquid pump is the primary determinant.

The Monoblock Pump HSN Classification

Monoblock pumps, being mechanical appliances designed to pump liquids, unequivocally fall under Chapter 84: “Nuclear reactors, boilers, machinery and mechanical appliances; parts thereof.” This chapter is the designated home for most industrial and mechanical equipment.

Specifically, the HSN heading 8413 is dedicated to: “Pumps For Liquids, Whether Or Not Fitted With A Measuring Device; Liquid Elevators.”

While the provided data doesn’t explicitly list “Monoblock pump” with a single HSN code, it offers several highly relevant subheadings that a monoblock pump would fall under, depending on its specific type and application. A monoblock pump is essentially a type of centrifugal or positive displacement pump that is “power driven” and “designed primarily for handling water.”

Based on the descriptions, a monoblock pump would most likely be classified under one of the following, usually with a 28% GST rate:

• For Centrifugal Pumps: Many monoblock pumps are centrifugal.
  • 84137094: “Other Centrifugal Pumps: Other: Vertical Turbine Driven Pumps” (though monoblocks are often horizontal, this indicates the type of pump).
  • The broader category for centrifugal pumps under HSN 8413 would apply.
• For Power Driven Pumps Primarily Designed for Handling Water:
  • The general description “Power Driven Pumps Primarily Designed For Handling Water, Namely, Centrifugal Pumps (Horizontal And Vertical), Deep Tube-Well Turbine Pumps, Submersible Pumps, Axial Flow And Mixed Flow Vertical Pumps” (HSN 8413) directly covers the function of most monoblock pumps. The data lists “8413” as the general heading for these.
  • Specific types of water pumps are listed:
    • 84133030: “Water Pump” (likely for internal combustion piston engines, but shows a general water pump classification).
    • 84138130: “Axial Flow And Mixed Flow Vertical Pump Designed Primarily For Handling Water.”
    • 84135021: “Deep Tube Well Turbine Pump.”
• Other Rotary Positive Displacement Pumps: If the monoblock pump is not centrifugal but a rotary positive displacement type.
  • 84136090: “Other Rotary Positive Displacement Pumps: Other.”

It is important to note that many of the specific pump types listed in the data (e.g., fuel pumps, metering pumps, deep tube well pumps) could potentially be manufactured in a “monoblock” design. The crucial factor for HSN classification is the pump’s core mechanical principle and its primary intended use (e.g., handling water, specific liquids).

The overwhelming majority of these liquid pumps (HSN 8413) attract a 28% GST rate, effective since November 15, 2017 (or July 1, 2017).

Other “pumps” mentioned in the data, like “Air or Vacuum Pumps” (HSN 8414) or “Heat Pumps” (HSN 8418), are distinctly different and fall under separate HSN codes and may have different GST rates (e.g., 18% for most air compressors and fans).
