Chapter 84 is the core chapter in the HS classification system covering machinery and mechanical appliances, and parts thereof. Its scope includes power machinery, pumps, fans, bearings, transmission devices, machine tools, hand tools, etc. Goods in this chapter generally have the characteristics of being power-driven, having mechanical motion, or performing energy conversion, but do not include purely electrical equipment (Chapter 85) and vehicles (Chapter 87). As a hydraulic-powered hand tool, the hydraulic hammer's core function conforms to the definition of 'machinery' in this chapter. Heading 8467 covers hand-held pneumatic or hydraulic tools and hand-held tools with self-contained power units (electric or non-electric). Specifically, it includes pneumatic drills, pneumatic hammers, hydraulic hammers, chain saws, polishers, etc. This heading emphasizes 'hand-held' and 'self-contained power,' distinguishing it from stationary machine tools (8457-8466) and hand tools (8205). As a hydraulically driven hand-held impact tool, the hydraulic hammer falls entirely within the scope of this heading. First 2 digits 84: Chapter 84, machinery and mechanical appliances, and parts thereof. Digits 3-4, 67: Heading 8467, hand-held pneumatic or hydraulic tools and hand-held tools with self-contained power units. Digits 5-6, 60: Subheading 846760, specifically referring to hydraulic hammers. Note: Under heading 8467, goods are further subdivided by power type and tool type: 846711 for pneumatic rotary tools, 846719 for other pneumatic tools, 846721-846729 for electric tools, 846781 for chain saws, 846789 for other hydraulic tools, and 846791-846799 for parts. 846760 specifically refers to hydraulic hammers, i.e., hand-held hammering tools driven by hydraulic oil pressure to actuate an impact mechanism. Hydraulic hammers are classified under 846760 rather than 846789 (other hydraulic tools) because their function is 'hammering' rather than rotating, cutting, or grinding. They are also not classified under the parts subheadings of 8467 (846791-846799) because that code refers to complete tools. The difference from 8462 (hydraulic presses) is that 8462 covers stationary, non-hand-held metalworking machine tools, whereas 846760 covers hand-held impact tools used in construction or maintenance.

Product Name: The specific name of the declared commodity, which should use standard Chinese or English, such as 'hydraulic hammer,' and avoid colloquial names. Brand: Fill in the manufacturer or trademark brand. If there is no brand, state 'no brand'; do not leave blank. Model: Fill in the specific model or specification, such as 'HM-1000,' to distinguish products of the same brand with different parameters. Power Type: Clearly state 'hydraulic drive,' distinguishing it from pneumatic or electric, which is key to classification under 846760. Use: Briefly describe the application scenario, such as 'hand-held impact tool for building demolition and mining.' Working Principle: Explain that hydraulic oil drives the piston in reciprocating impact, such as 'hydraulic oil pressure drives the impact piston.' Hand-held or Not: Clearly state 'hand-held' or 'portable,' which is the core characteristic of heading 8467. Complete Machine or Parts: Declare 'complete machine' or 'parts'; parts should be classified under 846791-846799. Example of customs declaration elements: Product Name: Hydraulic hammer; Brand: TOKU; Model: TH-1000; Power Type: Hydraulic drive; Use: For building demolition and concrete breaking; Working Principle: Hydraulic oil drives piston in reciprocating impact; Hand-held or Not: Hand-held; Complete Machine or Parts: Complete machine. Note: This commodity is a hand-held hydraulic tool, conforming to heading 8467, subheading 846760. Incorrectly declaring a hydraulic hammer as a pneumatic tool (846719), ignoring the difference in power type. Confusing hand-held hydraulic hammers with machine-mounted breakers, the latter of which may be classified under 8430. Failing to distinguish parts from complete machines, such as declaring the hammer head separately, which should be classified under 846799 rather than 846760.

Core criteria for classification: 1) Whether it is a hand-held tool; 2) Whether it has a self-contained power unit; 3) Whether the power type is hydraulic; 4) Whether the function is hammering. If all four points are met, it is classified under 846760. If it is stationary or not hand-held, consider 8462 (hydraulic presses) or 8430 (mining machinery). If pneumatic, classify under 846719; if electric, classify under 846729. Parts are classified under 846791-846799. 846719 Other pneumatic tools: The power source is compressed air, not hydraulic oil. Hydraulic hammers have higher pressure, greater impact force, and usually come with hydraulic lines. 846729 Other electric tools: The power source is an electric motor, requiring an external power supply or battery. Hydraulic hammers have no electric motor and rely on a hydraulic pump station for oil supply. 846789 Other hydraulic tools: Covers non-hammering tools such as hydraulic wrenches and hydraulic shears. Hydraulic hammers are specifically for impact breaking and have a single function. 8462 Hydraulic presses: Stationary, non-hand-held, used for metal sheet processing. Hydraulic hammers are hand-held, used for building demolition. 8430 Mining machinery: Includes machine-mounted breakers, drilling rigs, etc., usually installed on excavators or rigs, not hand-held. Is it clearly a hand-held tool? Is the power type hydraulic? Is the function impact hammering? Does it have a self-contained power unit (or connect to a hydraulic pump)? Is it a complete machine rather than parts?

What is the difference in HS codes between hydraulic hammers and pneumatic hammers? Hydraulic hammers are classified under 846760, and pneumatic hammers under 846719. The difference lies in the power source: hydraulic hammers are driven by hydraulic oil, while pneumatic hammers are driven by compressed air. When declaring, the power type must be clearly stated, and corresponding technical documents provided. If a hydraulic hammer is mounted on an excavator, can it still be classified under 846760? No. 846760 only applies to hand-held hydraulic hammers. Machine-mounted breakers installed on excavators are excavator attachments and are usually classified under the excavator as a whole (8429) or separately under 8430. Under which code should parts of hydraulic hammers (such as hammer heads, pistons) be classified? Parts specifically for hydraulic hammers are classified under 846791 to 846799. Among these, 846799 covers parts for other hydraulic tools. If a hammer head is imported separately, it is usually classified as a part, but it must be confirmed whether it has an independent function. How can I check the import tariff rate for hydraulic hammers? The tariff rate must be checked according to the customs tariff of the destination country. For example, for China Customs, you can log on to the 'Customs Import and Export Tariff of the PRC' to check the MFN rate, general rate, and VAT for 846760. Tariff rates change, so it is recommended to refer to the latest tariff schedule. What certifications are required for exporting hydraulic hammers to the EU? The EU requires machinery products to comply with the Machinery Directive (2006/42/EC) and bear the CE mark. Hydraulic hammers must also meet noise, vibration, and other requirements. It is recommended to obtain CE certification and prepare technical files before export. How should the 'Working Principle' field be filled in during declaration? It should concisely describe how hydraulic oil drives the piston in reciprocating motion to generate impact force. For example: 'A hydraulic pump provides high-pressure oil to push the piston to impact the hammer head.' Avoid vague expressions such as 'breaking.' Are hydraulic hammers and hydraulic breakers the same commodity? Yes, hydraulic breaker is a common name for hydraulic hammer, both referring to hand-held hydraulic impact tools classified under 846760. However, 'breaker' sometimes also refers to machine-mounted types, which should be distinguished based on whether they are hand-held. If a hydraulic hammer comes with an electric hydraulic pump station, how should it be classified? If the hydraulic hammer is imported together with an electric pump station, and the pump station provides power for the hammer, it is usually classified as a complete set of tools, still under 846760. If the pump station is imported separately, it is classified under 8413 (hydraulic pumps).
