Chapter 84 is the core chapter in the HS classification covering mechanical machinery and parts, including power machinery, pumps, fans, machine tools, construction machinery, office equipment, etc. This chapter emphasizes the 'work-performing' function of machinery, that is, achieving energy conversion or material processing through mechanical motion. As a hand-held tool powered by compressed air, the pneumatic hammer falls within the 'hand tools' category of this chapter, and is distinguished from electric tools (8508) and hydraulic tools (8467). Heading 8467 covers hand-held pneumatic tools or tools with a self-contained non-electric motor, including pneumatic hammers, pneumatic drills, pneumatic wrenches, pneumatic grinders, etc. The core features are 'hand-held' and 'non-electric power source,' usually driven by compressed air. This heading also includes parts of such tools (such as hammer heads, cylinders). Note the distinction from 8466 (machine tool parts) and 8205 (hand tools). First 2 digits 84: Chapter 84, mechanical machinery and parts. Digits 3-4: 67: heading 8467, hand-held pneumatic tools and parts. Digits 5-6: 40: subheading 846740, pneumatic hammers. Specifically, 8467.11 is for rotary (including impact) pneumatic drills, 8467.19 is for other pneumatic drills, 8467.21 is for pneumatic wrenches, 8467.29 is for other pneumatic tools, and 8467.40 is for pneumatic hammers. Therefore, 846740 specifically refers to hand-held hammers powered by compressed air and used for striking or impact operations. Pneumatic hammers are classified under 846740 because their power source is compressed air (non-electric) and they are hand-held tools. Adjacent codes such as 846719 (other pneumatic drills) are used for rotary drilling, 846729 (other electric tools) are used for electric drive, and 8205 (hand tools) are used for manual drive. The impact function of a pneumatic hammer differs from rotary drilling, so it is classified under 846740.

🎯 Classification Logic
Core classification basis: 1) Power source is compressed air (non-electric); 2) Hand-held design; 3) Function is impact hammering. According to HS notes, 8467 includes 'hand-held pneumatic tools,' and pneumatic hammers meet the definitions of 'pneumatic' and 'hand-held.' If fixed type, classify under 8462 (forging or stamping machine tools) or 8463 (other machine tools). If electric, classify under 8467.29 or 8508. If parts are dedicated parts such as hammer heads, they are also classified under 8467.40. 846719 Other pneumatic drills: 846719 is a rotary drilling tool, while 846740 is an impact hammering tool; their functions differ. 846729 Other electric tools: 846729 is electrically driven, while 846740 is pneumatically driven; the power source is the core difference. 8205 Hand tools: 8205 is manually driven and has no self-contained power source, while 846740 requires compressed air drive. 8462 Forging or stamping machine tools: 8462 is fixed type and non-hand-held, used for metalworking, while 846740 is a hand-held pneumatic hammer. 8463 Other machine tools: 8463 includes fixed pneumatic hammers, but 846740 specifically refers to hand-held ones; the installation method differs. Is the power source compressed air? Is it a hand-held design? Is the function impact hammering? Is it used for materials such as metal and concrete? Is it distinguished from 846719, 846729, etc.?

❓ FAQ
What is the difference in HS codes between pneumatic hammers and electric hammers? Pneumatic hammers are classified under 846740, with compressed air as the power source; electric hammers are classified under 846729 (other electric tools) or 8508 (electric tools), with electricity as the power source. The core difference between the two lies in the power source, and 'pneumatic' or 'electric' must be clearly filled in during declaration. How can one determine whether a pneumatic hammer is hand-held or fixed? A hand-held pneumatic hammer can be operated by hand, is relatively light in weight, and usually has a handle; a fixed pneumatic hammer is installed on a frame or robotic arm and used in production lines. Hand-held ones are classified under 846740, and fixed ones under 8462 or 8463. A description of the method of use must be provided during declaration. How are parts of pneumatic hammers classified? If dedicated parts of pneumatic hammers (such as hammer heads, cylinders, impact mechanisms) are parts of hand-held pneumatic hammers, they are classified under 846740; if they are parts of fixed pneumatic hammers, they are classified under the parts subheadings of 8462 or 8463. General parts (such as bolts) are classified according to material. How should 'Working Principle' be filled in among the declaration elements for a pneumatic hammer? It should be filled in as 'impact reciprocating type' or 'hammering type,' emphasizing its impact function rather than rotation. If 'rotary type' is filled in, it may lead to classification under 846719. The working principle must be consistent with the actual item, avoiding vague descriptions. What should be noted when querying the HS code for a pneumatic hammer? When querying, confirm the first 6 digits 846740 and note differences in national subheadings. For example, the U.S. HTS may subdivide further, but the first 6 digits are internationally uniform. It is recommended to use the General Administration of Customs or WCO database and verify in combination with elements such as product name, power source, and hand-held nature. Are the HS codes for pneumatic hammers and hydraulic hammers the same? No. If a hydraulic hammer is hand-held, it is classified under 8467.89 (other hand-held tools); if fixed, under 8462 or 8463. Pneumatic hammers are classified under 846740, with compressed air as the power source, while hydraulic hammers use hydraulic oil as the power source; the classifications differ. What issues should be noted when declaring pneumatic hammers for cross-border e-commerce sales? Elements such as product name, brand, model, power source, and use must be accurately declared to avoid classification errors caused by mistakenly reporting 'electric.' At the same time, note the destination country's access requirements, such as CE certification and noise standards. It is recommended to keep product manuals and pictures for customs inspection. Does the HS code for pneumatic hammers apply to all types of pneumatic hammers? 846740 applies to hand-held pneumatic hammers, including breaker hammers, rivet hammers, impact hammers, etc. However, if they are fixed or non-hand-held, it does not apply. In addition, if a pneumatic hammer has other functions (such as drilling), it must be classified according to the principal function.
