Product classification
HS code for Blow molding machine: 8477.30
Machinery, blow moulding machines, for working rubber or plastics or for the manufacture of products from these materials.
Classification of blow molding machine under HS 8477.30
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.

Codes often confused with 8477.30
Common mistake. 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.
Top exporters and importers of HS 847730 (the code used for blow molding machine), 2025
In 2025, the largest exporter of HS 847730 (the code used for blow molding machine) in UN Comtrade data was China, with 28% of world exports; the largest importer in UN Comtrade data was the United States, with 14% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
