Chapter 84 is the core chapter in HS classification covering machinery, mechanical appliances and their parts, including power machinery, pumps, fans, machine tools, office equipment, etc. This chapter emphasizes the mechanical function and power-driven attributes of goods. Parts classification requires determining whether they are dedicated to a specific type of machinery. The overall scope ranges from boilers and engines to automatic data processing equipment, making it one of the most important chapters in industrial goods trade. Heading 8467 specifically refers to hand-held pneumatic tools or hand-held tools with self-contained non-electric power (such as pneumatic or hydraulic), including tools for drilling, tapping, screwdriving, grinding, riveting, etc. This heading covers the tool itself and its dedicated parts, but excludes electric tools (classified under 8508) or hand tools (classified under 8205). Parts must be clearly dedicated to tools under heading 8467. Code 846792 consists of 6 digits: the first 2 digits 84 represent Chapter 84 (machinery and mechanical appliances); digits 3-4, 67, represent heading 8467 (hand-held pneumatic or non-electric power tools); digits 5-6, 92, represent subheading 846792, specifically referring to parts of tools under heading 8467. The 5th digit 9 indicates a parts subheading, and the 6th digit 2 further subdivides. The overall logic is: chapter → heading → subheading, progressively narrowing down to parts dedicated to pneumatic tools. This commodity is a part dedicated to pneumatic tools, possessing the characteristic of being dedicated to pneumatic tools under heading 8467, and is therefore classified under 846792. If it were a part for electric tools, it should be classified under 8508; if it were a general-purpose mechanical part, it would be classified by material or use. 846792 emphasizes 'dedication' — it cannot be a general-purpose part, and the tool itself must be hand-held, pneumatic or non-electric power-driven.

🎯 Classification Logic
The core basis for classification is: 1) whether the tool itself is hand-held, pneumatic or non-electric power-driven; 2) whether the part is dedicated to that tool. If the part can be used generally with other machinery, it is classified as a general-purpose part (such as 7318, 7326, etc.). If the tool is electric, the parts are classified under 8508. Reference is also made to the Explanatory Notes to the Import and Export Tariff for heading 8467. 846791 Parts of hand-held chainsaws: 846791 specifically refers to parts of hand-held chainsaws (regardless of power source), while 846792 only refers to parts of pneumatic tools. Chainsaw parts are not classified under 846792. 846799 Parts of other hand-held tools: 846799 covers parts of other tools under heading 8467 (such as hydraulic tools), while 846792 is limited to parts of pneumatic tools only. 8508 Electric tools: 8508 covers complete electric tools and their parts, with electric power as the power source. If parts are used for electric tools, they should be classified under 8508 rather than 846792. 8205 Hand tools: 8205 covers hand tools without power drive. If parts are used for hand tools, they are classified under 8205, not 846792. 8487 Machine parts: 8487 covers other machine parts not elsewhere specified in this chapter. If pneumatic tool parts are not dedicated to heading 8467, they may be classified under 8487. Is the tool hand-held and pneumatically driven? Is the part dedicated to that tool? Can the part be used generally with other machinery? Is it confused with electric tool parts? Is it confused with hand tool parts?

❓ FAQ
How are pneumatic tool parts and electric tool parts distinguished in HS codes? The core difference lies in the power source of the tool. Pneumatic tool parts are classified under 846792, and electric tool parts under 8508. If a part can be used for both pneumatic and electric tools, it needs to be determined based on the principal use; if it cannot be determined, it may be classified as a general-purpose part. The tool type and model should be provided at the time of declaration. Does 846792 include general-purpose parts such as sealing rings and springs? No. 846792 only covers parts dedicated to pneumatic tools. If sealing rings, springs, etc. are general-purpose standard parts, they should be classified by material (e.g., rubber sealing rings under 4016, steel springs under 7320). Only such parts specifically designed for a particular pneumatic tool may be classified under 846792. How to determine whether a part is 'dedicated' to a pneumatic tool? The determination of dedication is based on: whether the part is only applicable to tools under heading 8467 and cannot be used for other machinery. Usually, part drawings, applicable tool models, and function descriptions need to be provided. If the part is generally used in the market for multiple types of machinery, it is considered a general-purpose part and is not classified under 846792. What is the relationship between the HS codes for complete pneumatic tools and their parts? Complete pneumatic tools are classified under specific subheadings under heading 8467 (such as 846711, 846719, etc.), and their dedicated parts are classified under 846792. Complete tools and parts are classified separately, but the parts must be dedicated to the complete tool. If parts are imported together with the complete tool, they must be declared separately. In the declaration elements for 846792, is 'Applicable Tool Model' mandatory? It is recommended to provide it. This element is key to proving the dedication of the part, and its absence may lead to customs questioning the classification. If there is truly no model number, detailed information such as the tool name and function should be provided, along with a declaration of dedication. What does customs focus on during valuation when pneumatic tool parts are imported? Customs valuation focuses on the authenticity, dedication, and price reasonableness of the parts. Contracts, invoices, and parts lists need to be provided, along with an explanation of the part's function in the complete tool. If the price is significantly lower or higher than similar goods, supplementary explanation may be required. If pneumatic tool parts are imported as complete sets of unassembled components, how are they classified? If the complete set of unassembled components already has the essential character of the complete tool, it should be classified as the complete tool (8467). If the unassembled components are clearly parts, they are still classified under 846792. The specific determination is based on General Interpretative Rule 2(a) of the Tariff. Are special documents required when exporting parts under 846792? Generally, no special documents are required, but if brands or intellectual property are involved, an authorization letter is needed. If the parts are dual-use items or subject to export control, relevant licenses must be obtained. It is recommended to check the latest export regulatory conditions.
