Chapter 84 is the core chapter in HS classification covering machinery and mechanical appliances, including power machinery, processing machinery, handling equipment, office machinery, etc. This chapter aims to distinguish devices operating on mechanical principles, complementing Chapter 85 on electrical equipment. Rubber molding machines, as machinery for processing rubber, involve pressure, temperature, and mold forming, making them typical processing machinery, and are therefore classified in this chapter. Heading 8477 covers machines within this chapter for processing rubber or plastics and products thereof, including injection molding machines, extruders, blow molding machines, vacuum molding machines, and other molding machines. This heading includes not only complete machines but also their auxiliary equipment such as molds (however, molds if separately presented shall be classified according to their specific material). The core requirement is that the machine must be used for the molding or processing of rubber or plastics. First 2 digits 84: indicates Chapter 84, i.e., nuclear reactors, boilers, machinery and mechanical appliances and parts thereof. Digits 3-4, 77: indicates heading 8477, specifically for machines for processing rubber or plastics and products thereof. Digits 5-6, 59: indicates subheading 8477.59, i.e., other rubber molding machines. Among these, 8477.10 is injection molding machines, 8477.20 is extruders, 8477.30 is blow molding machines, 8477.40 is vacuum molding and other thermoforming machines, and 8477.51 to 8477.59 are other molding machines or machines for making other products. 8477.59 specifically refers to rubber molding machines not elsewhere specified, such as compression molding machines, transfer molding machines, calenders, etc. The goods are rubber molding machines, but are not specifically named as injection molding, extrusion, blow molding, or vacuum thermoforming, and are therefore classified under 8477.59. If they were plastic molding machines, they might be classified under 8477.59 (other plastic molding machines) or 8477.80. However, according to the subheading structure, 8477.59 is explicitly for rubber molding machines, thus distinguishing it from 8477.80 (other machines) and 8477.90 (parts).

Product Name: The Chinese and English names of the declared goods, which must be consistent with the contract and invoice, indicating the specific type such as compression molding machine, transfer molding machine, etc. Use: Explain that the machine is used for processing rubber products, such as tires, sealing rings, rubber hoses, etc., and specify the product type. Working Principle: Describe the molding method, such as compression molding, transfer molding, injection molding, etc., and briefly describe the mold closing, heating, and pressing process. Brand: Fill in the machine brand; if no brand, write 'No Brand'; must be consistent with the physical nameplate. Model: Fill in the specific model to distinguish different specifications; must be consistent with the declaration. Power: Fill in the total power of the machine (in kilowatts), reflecting equipment specifications and assisting in classification determination. Brand Type: Fill in according to customs regulations: Foreign Brand (OEM Production), Foreign Brand (Other), Domestic Brand, No Brand. Export Preference Status: If an export preferential trade agreement is involved, fill in 'Export Preference' or 'No Preference', and indicate the agreement name. Product Name: Rubber Compression Molding Machine; Use: For producing rubber sealing rings; Working Principle: Rubber raw material is placed into the mold, formed by hydraulic pressing and heating curing; Brand: XXX; Model: XXX-100; Power: 15KW; Brand Type: Domestic Brand; Export Preference Status: No Preference. Mistakenly classifying rubber molding machines under 8477.80 (other machines), ignoring that 8477.59 is specifically established for rubber molding machines. Failing to distinguish between rubber and plastic molding machines, leading to incorrect subheading selection. Unclear description of working principle, such as mistakenly reporting compression molding as injection molding, affecting classification.

The core basis for classification is whether the material processed by the machine is rubber, and whether the molding method falls within the scope listed under subheading 8477.59. First, according to the chapter notes of Chapter 84, the machine must have an independent function. Second, heading 8477 covers rubber or plastic processing machines, but subheading 8477.59 is explicitly for rubber molding machines. Therefore, it must be confirmed that the machine is dedicated to rubber and that the molding method is not injection molding, extrusion, blow molding, or vacuum thermoforming. If the machine can process both plastics and rubber, it shall be classified according to its principal use. 8477.10 Injection Molding Machines: Injection molding machines inject molten material into molds, suitable for plastics or rubber, but subheading 8477.10 is for injection molding machines; if it is a rubber injection molding machine, it is classified under 8477.10 rather than 8477.59. 8477.20 Extruders: Extruders extrude continuous profiles through a screw, used for rubber or plastics, but subheading 8477.20 is for extruders; rubber extruders are classified here. 8477.30 Blow Molding Machines: Blow molding machines are used for hollow molding, subheading 8477.30; rubber blow molding machines are relatively rare, but if for rubber, they are classified here. 8477.40 Vacuum Molding and Other Thermoforming Machines: Vacuum molding machines are used for thermoforming, subheading 8477.40; rubber thermoforming machines using vacuum molding are classified here. 8477.80 Other Machines: Subheading 8477.80 is for other rubber or plastic processing machines, such as vulcanizing machines, cutting machines, etc., but molding machines not elsewhere specified are classified under 8477.59 (rubber) or 8477.80 (plastics). Is the machine dedicated to rubber processing? Is the molding method compression, transfer, or other non-injection/extrusion/blow/vacuum? Does it have an independent function? Does it conflict with subheadings such as 8477.10, 8477.20, etc.? Does it need to be classified according to principal use?

How are rubber molding machines and plastic molding machines distinguished in HS codes? Rubber molding machines are classified under subheading 8477.59, while plastic molding machines are classified according to the molding method under 8477.10 (injection molding), 8477.20 (extrusion), etc.; if not elsewhere specified, under 8477.80. The key is the processed material and molding method. Are both compression molding machines and transfer molding machines classified under 8477.59? Yes, both compression molding machines and transfer molding machines belong to other rubber molding machines, because subheading 8477.59 covers rubber molding machines not elsewhere specified, including these two types. If a machine can process both rubber and plastics, how is it classified? According to General Rule of Interpretation 3(b), it shall be classified according to its principal use. If mainly for rubber, then 8477.59; if mainly for plastics, then classified as a plastic molding machine. Which code should rubber injection molding machines be classified under? Rubber injection molding machines should be classified under 8477.10, because subheading 8477.10 is explicitly for injection molding machines, regardless of whether processing rubber or plastics. In the declaration elements for 8477.59, how should the working principle be filled in? The molding method should be described in detail, such as 'Rubber raw material is placed into the mold, pressed hydraulically and heated, causing the rubber to vulcanize and form,' avoiding a vague description of 'molding.' How are parts of rubber molding machines classified? If parts are separately presented, they should be classified under 8477.90, but note that if the part is a mold, it is classified according to the mold material (e.g., 8480). Can exporting rubber molding machines to ASEAN enjoy the agreement rate? It is necessary to check the China-ASEAN Free Trade Agreement tariff schedule to confirm whether HS code 8477.59 is on the tariff reduction list. A certificate of origin and other documents are also required. How to check the MFN rate for 8477.59? You can visit the website of the General Administration of Customs of China or use the customs tariff inquiry system, enter HS code 8477.59 to view the latest rate, noting that rates may be adjusted annually.
