HS Code for Blow molding machine

The classification of blow molding machines under HS code 8477.30 is determined by the General Rules for the Interpretation (GRI) of the Harmonized System. Specifically, Chapter 84 covers nuclear reactors, boilers, machinery, and mechanical appliances. Within this chapter, heading 8477 is dedicated to machinery for working rubber or plastics or for the manufacture of products from these materials, not specified or included elsewhere in the chapter. Blow molding is a distinct manufacturing process where plastic is melted and formed into a hollow tube known as a parison, which is then inflated against a mold cavity to create a specific shape. Because this machine is specialized for the plastic and rubber industry and utilizes the blow molding technique, it is classified under the specific subheading 8477.30. This classification applies regardless of whether the machine uses extrusion, injection, or stretch-blow methods, provided the primary function is the production of hollow plastic articles like bottles or containers.

Products Included

• Extrusion blow molding machines
• Injection blow molding machines
• Stretch blow molding machines
• Reheat and blow machines for PET bottles
• Accumulator head blow molding systems

Common Misclassification

It is frequent for importers to confuse 8477.30 with 8477.10, which is reserved for injection molding machines. While both processes involve plastic, injection molding forces molten material into a closed mold, whereas blow molding uses air pressure to expand a parison. Another common error is using 8477.20, which covers extruders. While many blow molding machines incorporate an extrusion unit to create the parison, the essential character of the finished machine is the blowing and molding function. Additionally, the molds themselves must be classified under 8480.71, as they are considered interchangeable tools rather than part of the machine's primary classification.

FAQ

What is the HS code for blow molding machines?

The primary HS code for blow molding machines used for working plastics or rubber is 8477.30.

Does this code include the molds used in the machine?

No, molds for rubber or plastics are classified separately under heading 8480, specifically 8480.71 for injection or compression types and 8480.79 for others.
