Chapter 84 is the core chapter in the HS classification covering mechanical equipment and parts, including power machinery, pumps, fans, lifting and handling equipment, construction machinery, printing machinery, textile machinery, etc. This chapter has an extremely broad scope, and may include items ranging from small household tools to heavy industrial equipment, but explicitly excludes electrical equipment (Chapter 85), vehicles (Chapter 87), and optical instruments (Chapter 90). To understand this chapter, one must grasp the main thread of 'mechanical function,' namely devices that use mechanical energy to complete specific physical actions. Heading 8431 specifically covers parts of the machinery listed in headings 8425 to 8430, including dedicated parts for handling or engineering machinery such as pulley blocks, cranes, forklifts, excavators, scrapers, etc. Parts under this heading must be used in conjunction with the main machine and must not constitute a complete machine, and must not be general-purpose parts more specifically named in other headings (such as bolts, gears, etc.). As its subheading, 843139 specifically refers to other handling machinery parts other than the main machine parts of headings 8425 to 8430. The first 2 digits '84' represent Chapter 84, namely nuclear reactors, boilers, machinery, mechanical appliances and their parts, establishing the broad category that the goods belong to machinery. The 3rd-4th digits '31' represent heading 8431, namely parts specially or principally for the machinery of headings 8425 to 8430, defining the type of main machine to which the parts belong. The 5th-6th digits '39' represent subheading 843139, namely 'other handling machinery parts,' which is a residual subheading further subdivided under 8431 to cover handling machinery parts other than those in 843131 (parts of lifts, elevators) and other than 843139. The goods are classified under 843139 because they are dedicated parts of handling machinery and are not named in more specific subheadings such as 843131 (elevator parts). The difference from the adjacent code 8483 (transmission shafts, gears and other general mechanical parts) is that 843139 parts must be specially for handling machinery, whereas 8483 parts are of a general-purpose nature. In addition, if the part itself constitutes a complete machine or belongs to Chapter 87 vehicle parts, it should not be classified under this code.

🎯 Classification Logic
The core basis for classification is the dedicated nature of the part: it must be specially or principally for the handling machinery of headings 8425 to 8430, and must not be specifically named in other subheadings. At the same time, general-purpose parts (such as 8483) and components constituting a complete machine must be excluded. Customs will examine the matching relationship between the part and the main machine, its function, and its material. 843131 Parts of lifts, elevators: 843131 is dedicated to lifts or elevators, while 843139 covers parts of other handling machinery (such as forklifts, cranes). 8483 Transmission shafts, gears, etc.: 8483 covers general mechanical transmission parts and is not limited to handling machinery; if a part is dedicated to handling machinery, it should be classified under 843139. 843149 Other engineering machinery parts: 843149 covers parts of engineering machinery such as excavators and scrapers, while 843139 targets handling machinery parts. 842890 Other handling machinery: 842890 is complete handling machinery, while 843139 is its dedicated parts; the two are in the relationship of complete machine and parts. Is the part dedicated to handling machinery? Does it belong to general-purpose parts (such as bolts, gears)? Has it already been named in other subheadings (such as 843131)? Does it constitute a complete machine? Does it belong to Chapter 87 vehicle parts?
