Chapter 84 is one of the broadest chapters in the HS classification, covering various machines, mechanical appliances, power equipment, and their parts. From steam boilers and internal combustion engines to machine tools, computers, bearings, and seals, all are classified under this chapter. Its core characteristic is that goods must have mechanical motion or energy conversion functions and are typically for industrial or engineering use. Injection molding machines, as equipment that injects plastic melt into molds for shaping through mechanical pressure, fully conform to this chapter's definition of mechanical appliances. Heading 8477 specifically covers machinery for working rubber or plastics or for the manufacture of products from these materials, not specified or included elsewhere in this chapter. It includes injection molding machines, extruders, blow molding machines, calenders, vacuum forming machines, etc. The key criterion for this heading is that the machine must be used for processing rubber or plastic raw materials (such as pellets, powder, liquid) or semi-finished products, and the processing method must be shaping or reshaping. Injection molding machines are classified under this heading because they shape plastic raw materials into products through steps such as injection, holding pressure, and cooling. First 2 digits 84: represents Chapter 84, i.e., nuclear reactors, boilers, machinery, mechanical appliances, and their parts. Digits 3-4, 77: under Chapter 84, heading 8477 represents machinery for working rubber or plastics or for the manufacture of products from these materials. Digits 5-6, 10: subheading 847710, further limited to injection molding machines. Therefore, the complete code 847710 means: under Chapter 84 (mechanical appliances), heading 8477 (plastics working machinery), subheading 10 (injection molding machines). This coding hierarchy reflects the logical classification from broad category to specific commodity. Injection molding machines are classified under 847710 rather than other codes, primarily because their function is to process plastics. If a machine is used for processing metal, it should be classified under machine tool headings such as 8454-8463; if used for processing wood, under 8465. Although injection molding machines involve molds, the molds themselves are classified under 8480, while injection molding machines as complete machines are classified based on the processing object and molding method. Therefore, 847710 is the only correct classification for injection molding machines.

🎯 Classification Logic
The core criterion for classification is the machine's processing object and molding method. Injection molding machines must be used for processing plastics or rubber and shape materials in molds through steps such as injection, holding pressure, and cooling. If a machine is used for processing metal, it should be classified under 8454-8463; if used for processing wood, under 8465; if it is a plastic extruder, under 847720; if it is a blow molding machine, under 847730. Therefore, correct classification requires both: the processing object is plastic and the molding method is injection. 847720 Extruder: Extruders continuously extrude plastics through a screw to produce pipes, profiles, etc., while injection molding machines are intermittent injection molding, producing discrete products. 847730 Blow Molding Machine: Blow molding machines are used to produce hollow products such as bottles, by inflating parisons, while injection molding machines inject melt to fill molds. 847740 Vacuum Forming Machines and Other Thermoforming Machines: Vacuum forming machines use vacuum suction to shape thermoplastic sheets, while injection molding machines use molds to inject melt. 848071 Injection or Compression Molds for Rubber or Plastics: This code is for the mold itself, which is an accessory of the injection molding machine, while the injection molding machine is a complete machine and must be classified separately. 845430 Metal Die-Casting Machine: Die-casting machines are used for metal molding, with metal as the processing object, while injection molding machines process plastics, with different classification. Confirm whether the machine is used for processing plastics or rubber. Confirm whether the molding method is injection molding. Confirm whether it has an injection device and a clamping device. Confirm whether it is declared separately from the mold. Confirm whether other molding methods such as extrusion and blow molding are excluded.

❓ FAQ
How to distinguish injection molding machines from die-casting machines in HS codes? Injection molding machines process plastics and are classified under 847710; die-casting machines process metals and are classified under 845430. The core difference lies in the processing object, and customs will focus on verifying equipment use and processing materials. Can used injection molding machines be exported using 847710? Yes, HS codes do not distinguish between new and used, but attention must be paid to the destination country's access requirements for used equipment. When declaring, information such as equipment condition and years of use must be provided, and pre-shipment inspection may be required. How are molds accompanying injection molding machines classified? The mold itself should be classified under 848071 (injection or compression molds for rubber or plastics) and declared separately from the injection molding machine. If the mold and machine are imported together, the product name and code must be listed separately. How are parts of injection molding machines classified? Specialized parts such as injection screws and barrels, if they meet the notes to Chapter 84, are generally classified under 847790; general parts such as bolts and bearings are classified by material. It is recommended to consult the notes to Chapter 84 and classification decisions. How to check the import tariff rate for injection molding machines? Tariff rates vary by country, trade agreement, and annual adjustments. They can be checked through the official website of the customs administration, announcements of the tariff commission, or professional databases. It is recommended to use HS code 847710 to search on the target country's customs website. When declaring injection molding machines, must injection capacity and clamping force be provided? Yes, these are core declaration elements used by customs to confirm equipment specifications and classification. If omitted, it may lead to inspection, supplementary tax, or administrative penalties. Be sure to fill in according to actual parameters. Do all-electric injection molding machines and hydraulic injection molding machines have the same code? Yes, both are classified under 847710. HS codes are based on function rather than drive type. However, when declaring, the drive type must be indicated so that customs can understand the equipment characteristics. Will the HS code change when exporting injection molding machines to different countries? The first 6 digits 847710 are globally unified under the HS International Convention, but countries may subdivide the latter digits. For example, the US HTSUS is 8477.10.00, and the EU is 8477.10.00.
