Chapter 84 is the core chapter in the HS classification system covering mechanical equipment, including power machinery, metalworking machine tools, industrial processing equipment, etc. Goods in this chapter usually have the characteristics of being driven by mechanical power and being able to independently perform specific processing functions. Rubber and plastics processing machinery, as basic equipment for industrial manufacturing, is explicitly included in this chapter, reflecting its important position in global trade. Heading 8477 specifically covers machinery in this chapter for processing rubber or plastics and articles thereof. It includes injection molding machines, extruders, blow molding machines, calenders, vulcanizing equipment, etc., regardless of their heating, molding, cutting, or combining functions. However, if such machines are used for other materials (such as metal) or fall under other headings (such as molds, mold clamps), they are not classified under this heading. The first 2 digits 84: represent Chapter 84, namely nuclear reactors, boilers, machinery, mechanical appliances and parts thereof, covering the vast majority of industrial machinery. The 3rd-4th digits 77: within Chapter 84, 77 is the heading for machines and parts thereof specially for processing rubber or plastics, distinguishing it from processing metal (such as 8457-8466), wood (8465), etc. The 5th-6th digits 78: under heading 8477, subheading 8477.80 represents other rubber or plastics processing machines not elsewhere specified or included, while 8477.10 is injection molding machines, 8477.20 is extruders, 8477.30 is blow molding machines, etc. This code 847780 specifically refers to other processing equipment besides the main types such as injection molding, extrusion, and blow molding, such as calenders, vulcanizing machines, cutting machines, etc. This commodity is classified under 847780 because it is rubber or plastics processing machinery and does not fall under a more specific subheading (such as injection molding machines 847710, extruders 847720, blow molding machines 847730). If it is a mold or mold clamp, it should be classified under 8480; if it is a machine tool for processing metal, it is classified under 8457-8466; if it is a general-purpose part, it is classified according to material. Therefore, 847780 is a residual subheading covering rubber and plastics processing equipment not elsewhere specified or included.

Product Name: The Chinese and English names of the declared commodity should accurately reflect the function and use of the machine, such as "rubber calender" or "plastic thermoforming machine." Use: Explain what material the machine is used to process (rubber or plastics) and the specific production stage, such as "used for calendering and forming of plastic film." Working Principle: Briefly describe how the machine performs processing, such as "calendering through heated rollers" or "molding by compression vulcanization." Brand: Fill in the machine brand (such as "Haitian" or "ENGEL"); if there is no brand, fill in "no brand." Model: Fill in the model given by the manufacturer, such as "SJ-65" or "XLB-500." Specifications and Dimensions: Main technical parameters, such as screw diameter, calendering width, clamping force, etc., reflecting the machine's capacity. Power: Main motor power or total power, in kilowatts (kW), used to judge the scale of the machine. Product Name: Rubber calender; Use: Used for calendering and forming of rubber sheets; Working Principle: The rubber compound is calendered into thin sheets through heated rollers; Brand: Dalian Rubber & Plastics; Model: XY-3F-1730; Specifications and Dimensions: Roller diameter 610mm, calendering width 1730mm; Power: 75kW; Origin: China. Failure to distinguish between rubber and plastics processing; although both are under the same heading, the subheadings may differ. Declaring molds together with machines; molds should be classified under 8480. Ignoring the description of the working principle, resulting in mistaken classification under other processing machinery. Incomplete model filling, affecting customs review and subsequent audits.

The core basis for classification is the machine's function, processing object, and working principle. First determine whether it belongs to Chapter 84 machinery; second confirm whether it is specially used for rubber or plastics processing; then determine the subheading according to the processing method (injection molding, extrusion, blow molding, etc.). If the machine has multiple functions, classify according to the principal function. If it is a general-purpose part, classify according to material. Refer to the detailed explanation of 8477 in the Explanatory Notes to the Import and Export Tariff. 847710 Injection molding machines: Specially used for injection molding, while 847780 covers other processing equipment besides injection molding, such as calendering, vulcanization, cutting, etc. 847720 Extruders: Specially used for extrusion molding, while 847780 covers other equipment not elsewhere specified or included, such as thermoforming machines and calenders. 8480 Molds: Molds are tools used for molding and do not have independent power, while 847780 covers complete machines. 8457 Metalworking machine tools: The processing object is metal, while 847780 processes rubber or plastics. 8479 Other machinery: 8479 is for machinery not elsewhere specified or included; if it is clearly for rubber or plastics processing, it should preferentially be classified under 8477. Is the machine specially used for rubber or plastics processing? Does it have independent power and processing functions? Does it belong to a specified subheading such as injection molding, extrusion, or blow molding? Is it confused with molds or parts? Does the working principle support residual classification under 847780?

How can I check the specific tax rate for goods under 847780? You can check the latest Import and Export Tariff through the official website of the General Administration of Customs of China or the International Trade Single Window, enter HS code 847780, and view the MFN rate, general rate, VAT, and consumption tax. You can also consult a professional customs broker or use a tariff query tool, and note that tax rates may differ due to free trade agreements. Are rubber calenders and plastic calenders classified under the same code? Yes, both are classified under 847780 because heading 8477 covers rubber or plastics processing machinery and is not subdivided by material. However, when declaring, the processing object must be indicated for customs statistics and supervision. What special requirements are there for import declaration of used rubber and plastics processing machines? Pre-shipment inspection certificates, equipment condition statements, certificates of origin, etc. are required. When declaring, "used" and the years of use must be indicated, and customs may conduct inspection and valuation. Some old mechanical and electrical products are prohibited from import and must be confirmed in advance. How are parts for machines under 847780 classified? If the parts are specially used for 8477 machines, they should be classified under 8477.90; if they are general-purpose parts (such as bolts and gears), they are classified according to material (such as iron or steel under Chapter 73). Judgment should be based on the use and characteristics of the parts. How is the subheading determined for multifunctional rubber and plastics processing machines? Classify according to the principal function. If the principal function is injection molding, classify under 847710; if it is extrusion, classify under 847720; if the principal function cannot be determined or it is other processing, classify under 847780. A functional description must be provided when declaring. For rubber and plastics processing machines exported to the EU, is the HS code the same? The first 6 digits of the EU HS code are the same as those of China, all being 847780, but the later digits may differ. When exporting, declaration must be made according to the EU TARIC code, and attention should be paid to additional EU requirements such as CE certification and environmental directives. What is the difference between 847780 and 847759? 847759 is for other molding machines (such as vacuum forming and thermoforming), while 847780 is for other processing machines not elsewhere specified or included, such as calendering, vulcanization, and cutting. If the machine is used for molding, it should preferentially be classified under 847759. How should the "working principle" be described during declaration to avoid classification disputes? It should briefly and clearly explain how the machine performs processing, such as "calendering through heated rollers," "compression vulcanization molding," or "cutting by blades." Avoid vague wording and attach drawings or manuals when necessary.
