Chapter 84 is the broad category in the HS classification system for "nuclear reactors, boilers, machinery and mechanical appliances and parts thereof," covering a wide range of electromechanical products from power machinery to automated data processing equipment. This chapter emphasizes the functionality of goods, that is, achieving specific uses through mechanical movement or energy conversion, rather than materials or manufacturing processes. For computer-type products, this chapter mainly involves automatic data processing machines and their components, and is a core chapter for the classification of information technology products. Heading 8471 covers "automatic data processing machines and units thereof," including computers, laptops, tablets, servers, etc., as well as peripheral units such as monitors, keyboards, and storage devices. Under this heading, it is further subdivided by device type and processing capability, such as 8471.30 portable automatic data processing machines, 8471.41/49 other automatic data processing machines, etc. 8471.49 specifically refers to "other computers," that is, complete computers presented in the form of a system other than portable, mainframe, or minicomputers. Code 847149 is a 6-digit subheading. The first 2 digits "84" represent Chapter 84, namely nuclear reactors, boilers, machinery and mechanical appliances and parts thereof, covering all mechanical equipment. Digits 3-4 "71" represent heading 8471, namely automatic data processing machines and units thereof, including computers, storage devices, input/output devices, etc. Digits 5-6 "49" represent subheading 8471.49, namely "other computers," referring to automatic data processing machines not otherwise specified, usually in the form of a complete system, distinguished from portable (8471.30), mainframe (8471.50), etc. This subheading may be further subdivided by processing capability or configuration. This commodity is classified under 847149 because it is an automatic data processing machine, is not portable, not a mainframe, and not a minicomputer, and is usually presented in the form of a complete system with independent computing capability. Adjacent codes such as 847130 are for portable devices, 847150 for mainframes, and 847141 is in the same series but may have a different configuration. 847149 is a residual subheading applicable to other computer systems not specifically named.

Brand: Fill in the brand name of the computer, such as Lenovo, Dell, HP, etc.; if there is no brand, fill in "no brand." Model: Fill in the model assigned by the manufacturer, such as ThinkCentre M720, and it must be consistent with the actual item. Processor type: Fill in the CPU model and main frequency, such as Intel Core i7-9700 3.0GHz. Memory capacity: Fill in the memory size, such as 16GB DDR4, and the unit must be indicated. Hard drive capacity: Fill in the hard drive size and type, such as 512GB SSD, and the type must be indicated. Whether monitor is included: Fill in "yes" or "no," indicating whether a monitor is included at the time of declaration. Operating system: Fill in the preinstalled operating system, such as Windows 10 Pro; if none, fill in "none." Use: Fill in the main use, such as office, gaming, server, etc. Brand: Lenovo; Model: ThinkCentre M720; Processor: Intel Core i5-9400 2.9GHz; Memory: 8GB DDR4; Hard drive: 256GB SSD; Whether monitor is included: No; Operating system: Windows 10 Pro; Use: Office. Confusing memory and hard drive capacity, resulting in false declaration. Incorrect brand and model entry, affecting customs valuation and classification. Failure to indicate whether a monitor is included, which may lead to mistaken classification under 8471.60.

The core criteria for classification are: whether the device is an automatic data processing machine, whether it is presented in the form of a system, whether it has independent computing capability, and whether it belongs to already named subheadings such as portable or mainframe. 847149 is a residual subheading applicable to other computers not specifically named, usually including desktop computers, workstations, etc. If the device is portable, it should be classified under 847130; if it is a mainframe, under 847150. 847130 Portable automatic data processing machines: 847130 covers portable devices such as laptops and tablets, which are lightweight and battery-powered, while 847149 covers non-portable devices such as desktop computers. 847141 Other automatic data processing machines (under the same subheading): 847141 and 847149 both belong to 8471.4, but 847141 usually refers to systems with a certain processing capability, while 847149 is for others; the specific distinction depends on the subheading structure. 847150 Mainframes and minicomputers: 847150 specifically refers to mainframes and minicomputers, usually used in data centers, while 847149 refers to microcomputers. 847160 Input/output units: 847160 covers keyboards, mice, monitors, etc. If a computer is declared together with a monitor, it is still classified under 847149; if a monitor is declared separately, it is classified under 847160. Does the device have independent computing capability? Is it presented in the form of a complete system? Is it portable or a mainframe? Does it include peripheral devices such as a monitor? Are configurations such as processor and memory clear?

What is the difference between 847149 and 847130? 847130 specifically refers to portable automatic data processing machines, such as laptops and tablets, characterized by being lightweight and having a built-in battery. 847149 refers to other computers, usually non-portable devices such as desktop computers and workstations. If the device can be used portably, it should be classified under 847130. If a desktop computer host and monitor are declared together, which code should they be classified under? If the host and monitor are declared as a set system and the host has independent computing capability, they should be classified under 847149. If the monitor is declared separately, it is classified under 847160. If the host is declared separately, it is also classified under 847149. Should servers be classified under 847149? Server classification depends on their type. Mainframes and minicomputers are classified under 847150, while ordinary servers, if they are automatic data processing machines and are not portable, may be classified under 847149. However, note that some servers may be classified under 847141. It is recommended to judge based on processing capability and structure. How can I check the import tariff rate for 847149? Tariff rates change, so it is recommended to use the official website of the General Administration of Customs, China International Trade Single Window, or professional tariff query tools, and enter HS code 847149 along with the country of origin, trade mode, and other conditions to obtain the latest tariff rate. You may also consult a customs broker. What special documents are required when declaring 847149? Basic documents such as contracts, invoices, packing lists, and bills of lading are usually required. If sensitive components such as CPUs are involved, a brand authorization letter or certificate of origin may be required. The specific requirements are subject to customs. Are goods under 847149 subject to export controls? Some high-performance computers may be subject to export controls, which must be determined according to the Export Control Law of China and announcements by the Ministry of Commerce. If the computing power of a computer exceeds a certain threshold, an export license may be required. It is recommended to consult a professional lawyer or customs. If a computer has a preinstalled operating system, will the classification change? A preinstalled operating system does not affect classification, and it is still classified under 847149. However, the operating system information must be truthfully filled in at the time of declaration for customs valuation and statistics. Can second-hand computers be classified under 847149? Yes, but note that second-hand equipment may involve import prohibition or restriction regulations. At the time of declaration, "second-hand" and the condition rate must be indicated, and customs may require a test report.
