HS Code for Rubber extruder

A rubber extruder is classified under HS code 8477.20. This classification is based on the machine's primary function within the manufacturing sector. Chapter 84 covers nuclear reactors, boilers, machinery, and mechanical appliances. Heading 8477 is specifically dedicated to machinery for working rubber or plastics or for the manufacture of products from these materials, not specified elsewhere in the chapter. Subheading 8477.20 identifies extruders, which are machines that force heated rubber through a shaped die to create continuous profiles, tubes, or sheets. The classification follows GRI 1, as the machine is explicitly described by the text of the heading and subheading. It includes the entire assembly: the hopper, the heated barrel, the internal screw, and the motor drive system.

Products Included

• Single-screw rubber extruders
• Twin-screw extruders for rubber compounding
• Cold-feed and hot-feed rubber extruders
• Extruders for rubber tire tread production
• Silicone rubber extruders for medical tubing

Common Misclassification

Rubber extruders are often confused with 8477.10, which is reserved for injection-molding machines. While both process rubber, the method of forming the product (continuous extrusion vs. mold injection) is the deciding factor. Another misclassification is 8479.89, a general code for machines with individual functions. However, because 8477 specifically mentions rubber-working machinery, it takes precedence over the general machinery heading. Additionally, the dies used with the extruder are often misclassified; they should be under 8480.71 or 8480.79 depending on the material.

FAQ

What is the HS code for rubber extruder?

The HS code for a rubber extruder is 8477.20, which covers machinery for the extrusion of rubber or plastics.

Does this code include the cooling trough?

Usually, the cooling trough is classified separately under 8477.80 as auxiliary equipment, unless it is imported as a functional unit with the extruder under GRI 1.
