Chapter 84 is a core chapter in the HS classification system, covering nuclear reactors, boilers, machinery, mechanical appliances, and their parts. This chapter includes power machinery, agricultural machinery, processing machinery, office machinery, automatic data processing equipment, lifting and handling machinery, etc., but excludes electrical equipment (Chapter 85), optical instruments (Chapter 90), and vehicles (Chapter 87). Heading 8429 belongs to the key classification in the field of construction machinery within this chapter. Heading 8429 covers self-propelled bulldozers, graders, scrapers, excavators, loaders, tampers, and road rollers and other construction machinery. This heading specifically refers to earthmoving or road construction machinery that is self-powered and capable of moving on its own, excluding stationary or towed equipment (the latter is classified under 8479 or 8428, etc.). Under 8429, subheadings are further divided by machinery type and traveling method. Code 842940 is a six-digit subheading: the first 2 digits '84' represent Chapter 84 (machinery); digits 3-4 '29' represent heading 8429 (self-propelled bulldozers, graders, scrapers, excavators, loaders, tampers, and road rollers); digits 5-6 '40' represent subheading 842940, specifically referring to tampers and road rollers. This subheading further distinguishes tampers and road rollers, both used for compaction of soil or road surfaces. The goods are tampers or road rollers, which are self-propelled compaction machinery and conform to the description of heading 8429. They are not classified under 8428 (other lifting, handling machinery) because they do not have a handling function; not under 8479 (other machinery not elsewhere specified) because 8429 specifically names them; not under 8705 (special purpose vehicles) because road rollers are explicitly classified under 8429 in the HS, rather than as vehicles.

🎯 Classification Logic
The core basis for classification is: 1) whether the goods are self-propelled; 2) whether they are used for soil or road compaction; 3) whether they are specifically named under 8429. Tampers and road rollers are explicitly classified under 8429 in the HS Explanatory Notes, regardless of whether their traveling method is wheeled or crawler. If towed or walk-behind, 8428 or 8479 must be considered. In addition, if mounted on a vehicle chassis and the main function is transportation, it may be classified under 8705, but road rollers are generally not classified as vehicles. 8428 Other lifting, handling, loading and unloading machinery: 8428 covers handling and loading/unloading equipment, such as forklifts and conveyors; while 8429 is earthmoving or compaction machinery, with different functions. Towed road rollers may be classified under 8428. 8479 Other machinery of this chapter not elsewhere specified: 8479 is a residual heading, only used when the goods are not specifically named under 8429. Walk-behind road rollers, if not named, may be classified under 8479. 8705 Special purpose motor vehicles: 8705 includes crane trucks, concrete mixer trucks, etc., but road rollers are explicitly classified under 8429 in the HS, not as vehicles. 8430 Other excavating, leveling machinery: 8430 covers non-self-propelled excavating and leveling machinery, such as towed scrapers; 8429 is self-propelled. 8429 Other 8429 subheadings: Under 8429 there are also subheadings for bulldozers, excavators, etc.; 842940 specifically refers to tampers and road rollers, which need to be distinguished by function. Is it self-propelled? Is it used for soil or road compaction? Is it a tamper or road roller? Is it not towed or walk-behind? Is it not classified under 8705 or 8428?

❓ FAQ
What is the difference in declaration between tampers and road rollers under HS code 842940? Tampers are mainly used for impact compaction of railway ballast or soil, and the 'tamping method' must be indicated during declaration; road rollers are used for static or vibratory compaction of road surfaces or subgrades, and the 'compaction method' and 'traveling method' must be indicated. Both belong to 842940, but the declaration elements have different emphases. It is recommended to fill in accurately according to actual functions. Which HS code should towed road rollers be classified under? Towed road rollers, because they are not self-propelled, should not be classified under 8429, and are usually classified under 8428 (other handling machinery) or 8479 (machinery not elsewhere specified). The specific classification depends on their structure and function. It is recommended to provide detailed technical information for classification.
