Chapter 84 is the core chapter in the HS classification covering mechanical equipment and parts, including power machinery, pumps, compressors, fans, lifting and handling equipment, construction machinery, textile machinery, printing machinery, office machinery, automatic data processing equipment, etc. Goods in this chapter are mostly mechanical devices with independent functions, and their classification emphasizes function and use rather than material or manufacturing process. As an important material handling equipment heading within it, 8428 together with cranes, forklifts, elevators, etc. constitutes the industrial logistics equipment system. Heading 8428 covers other lifting, handling, loading and unloading machinery (for example: lifts, escalators, conveyors, cable cars, etc.), but excludes cranes, forklifts, elevators, etc. of headings 8425 to 8427. This heading mainly includes machinery for continuous transport of materials, such as belt, chain, and roller conveyors, as well as pneumatic lifts, screw conveyors, etc. The key feature of 8428 is that it is used for continuous or intermittent handling of materials in the vertical or horizontal direction, but does not include cranes mainly used for lifting heavy objects. Code 842820 is a six-digit subheading. The first two digits 84 represent Chapter 84 (mechanical equipment); digits 3-4, 28, represent heading 8428 (other lifting, handling, loading and unloading machinery); digits 5-6, 20, represent subheading 842820, specifically pneumatic lifts and conveyors. This subheading is further subdivided into pneumatic lifts and pneumatic conveyors, both of which use compressed air or airflow as the power source or conveying medium. In the HS system, the subheading level is usually distinguished according to power type, structural principle, or use. 842820 clearly takes 'pneumatic' as its technical feature, distinguishing it from mechanical, hydraulic, or electric handling equipment. This commodity is classified under 842820 because its core function is to use pneumatic principles to achieve vertical lifting or horizontal conveying of materials, which conforms to the scope of heading 8428, 'other lifting, handling, loading and unloading machinery.' It does not belong to the cranes of 8425 (not intermittent lifting of heavy objects), nor to the overhead cranes of 8426 or the forklifts of 8427. At the same time, it does not meet the specific structural requirements of other subheadings under 8428 such as 842810 (lifts) or 842833 (belt conveyors), and therefore is classified under 842820 based on its pneumatic characteristics.

Product Name: The standard name of the declared commodity, which should reflect the pneumatic lifting or conveying function, such as 'pneumatic lift' or 'pneumatic conveyor.' Use: Explain the industry and scenario in which the equipment is applied, such as 'used for vertical lifting in grain storage' or 'used for pneumatic conveying of chemical powders.' Working Principle: Briefly describe the pneumatic method, such as 'uses compressed air to drive a piston to lift materials' or 'uses airflow to convey particles in a pipeline.' Brand: Fill in the equipment brand or manufacturer name; if there is no brand, fill in 'no brand.' Model: Fill in the specific model or specification, such as 'QD-100.' Conveying Capacity: Indicate the conveying volume per unit time, such as '10 tons/hour' or '500 cubic meters/hour.' Main Material: Explain the material of the parts in contact with the materials or the main structure, such as 'carbon steel' or 'stainless steel.' Power: If it is an electric-pneumatic hybrid, indicate the motor power; for pure pneumatic, indicate air consumption. Customs declaration example: Product Name: Pneumatic lift Use: Used for vertical lifting of wheat flour in a flour mill Working Principle: Uses compressed air to drive a cylinder and push the hopper to rise and fall along the guide rail Brand: ABC Model: QD-200 Conveying Capacity: 5 tons/hour Main Material: Stainless steel Power: Air consumption 0.8 cubic meters/minute HS Code: 842820 Failure to indicate the 'pneumatic' feature, resulting in classification under other subheadings such as 842810 (lifts). Mistakenly declaring a pneumatic conveyor as 842833 (belt conveyor), ignoring the difference in power. Incomplete declaration elements, such as missing working principle or conveying capacity, affecting classification.

The core basis for classification is whether the equipment uses pneumatic principles to achieve lifting or conveying of materials and does not belong to the lifting or forklift equipment of 8425 to 8427. 842820 specifically refers to pneumatic lifts and conveyors, whose technical feature is the use of compressed air or airflow as the power source or conveying medium. If the equipment is mechanical, hydraulic, or electric, it may be classified under other subheadings of 8428. At the same time, it is necessary to confirm whether the equipment has a continuous conveying function rather than intermittent lifting. 842810 Lifts and bucket elevators: 842810 covers non-pneumatic lifts, such as hydraulic lifts and mechanical bucket elevators; 842820 is limited to pneumatic type, and the power source is different. 842833 Belt conveyors: 842833 is a belt-type continuous conveyor, relying on belt transmission; 842820 is pneumatic conveying, using airflow or pneumatic devices, and the structural principle is different. 842839 Other machinery for continuous transport of materials: 842839 covers other continuous conveyors not elsewhere specified, such as roller and chain types; 842820 is clearly pneumatic and is preferentially classified under 842820. 842890 Other lifting, handling, loading and unloading machinery: 842890 covers other equipment not elsewhere specified under 8428, such as loading and unloading platforms; 842820 is specific pneumatic equipment and is not classified under 842890. Does the equipment use pneumatic power or conveying method? Is it used for continuous or intermittent handling of materials? Does it belong to the cranes or forklifts of 8425-8427? Does it have lifting or conveying functions? Do the declaration elements fully describe the pneumatic characteristics?

What is the difference in HS codes between pneumatic lifts and hydraulic lifts? Pneumatic lifts are classified under 842820, while hydraulic lifts are usually classified under 842810. The power principles are different: pneumatic uses compressed air, while hydraulic uses liquid pressure. The working principle must be accurately declared during customs declaration to avoid confusion. How are pneumatic conveyors distinguished from belt conveyors? Pneumatic conveyors use airflow to convey materials in pipelines and are classified under 842820; belt conveyors rely on belts for continuous conveying and are classified under 842833. The key difference lies in the conveying medium and structure, and 'pneumatic' or 'belt-type' should be indicated during declaration. Does 842820 include pneumatic pipeline conveying systems? Yes, 842820 includes pneumatic pipeline conveying systems, such as pneumatic conveying devices, used for powdery and granular materials. However, it must be ensured that their core function is conveying rather than other processing. If it is pneumatic lifting equipment, it may be classified under 8425. What key elements must be provided when declaring 842820? Product name, use, working principle (pneumatic method), brand, model, conveying capacity, and main material must be provided. Working principle and conveying capacity are important bases for distinguishing classification, and their absence may lead to rejection or classification disputes. If a pneumatic lift is equipped with electric control, does it affect classification? It does not affect classification. As long as the core lifting function is achieved pneumatically, it is still classified under 842820. Electric control only assists operation and does not change the main power feature. However, it must be stated in the declaration that pneumatic is primary and electric is auxiliary. How can the export tax rebate rate for 842820 be checked? The export tax rebate rate must be determined according to the customs tariff and rebate policy of the current year. The latest rebate rate can be checked through the official website of the General Administration of Customs of China, the electronic port, or by consulting a customs broker. Note that rates are adjusted and the rate at the time of declaration shall prevail. Which code should parts of pneumatic lifts be classified under? Specialized parts are usually classified under 842890 (parts of other lifting and handling machinery), but if the part itself is a pneumatic component (such as a cylinder), it may be classified under 8412. It should be judged according to the function of the part, and a detailed description is recommended. For cross-border e-commerce small parcel exports of pneumatic conveyors, is formal customs declaration required? If the value exceeds the limit stipulated by customs, formal customs declaration is required and HS code 842820 must be declared. Small parcel exports must also truthfully declare the product name and code to avoid customs seizure or fines due to classification errors.
