Chapter 84 is one of the broadest chapters in the HS classification, covering various machines, mechanical appliances, machine parts, and complete equipment. Its core scope involves power machinery, pumps, fans, refrigeration equipment, machine tools, welding equipment, office machinery, automatic data processing equipment, etc. This chapter emphasizes the functionality of goods, namely machines or mechanical appliances with independent functions, as well as parts specially or principally used for such machines. Understanding Chapter 84 requires attention to its boundary with Chapter 85 (electrical equipment) and the basic rules for classifying parts. Heading 8468 covers welding equipment and parts thereof, specifically including: welding machines and apparatus using solder or fusion welding (such as arc welding machines, resistance welding machines, laser welding machines, etc.); machines and apparatus for hot spraying; and parts of the above machines or apparatus. This heading does not include machines used solely for cutting (classified under 8456), manual welding electrodes or welding wire (classified under 8311), or electrically heated welding equipment (classified under 8515). Therefore, 8468 mainly targets non-electrically heated welding equipment and its dedicated parts. Code 846890 is a 6-digit subheading. The first 2 digits 84 represent Chapter 84 (nuclear reactors, boilers, machinery, mechanical appliances and parts thereof); digits 3-4, 68, represent heading 8468 (welding machines and apparatus, other than those of heading 8515; machines and apparatus for hot spraying; parts of the above machines and apparatus); digits 5-6, 90, represent subheading 846890, namely "parts." Therefore, this code specifically refers to dedicated parts of welding equipment or hot spraying equipment under heading 8468, excluding complete welding equipment. Note: subheading 846890 covers only parts, while complete machines are classified under other subheadings of 8468 (such as 846810, 846820, etc.). This commodity is classified under 846890 because it is a dedicated part of welding equipment and does not belong to electrical equipment of Chapter 85 (such as parts of electrical welding equipment of 8515). When classifying, it is necessary to confirm: 1) whether the part is dedicated to welding equipment of 8468; 2) whether it is an electrical part (such as electrodes, cables, etc., which may be classified under 8544 or 8515). If the part has an independent function, it may be classified under other headings. Therefore, 846890 applies to dedicated parts of non-electrically heated welding equipment, such as welding torch nozzles, wire feeding mechanism parts, etc.

Product Name: The specific name of the declared commodity, which should accurately reflect the purpose and material of the part, such as "contact tip for arc welding machine." Avoid using general names such as "welding parts." Purpose: State for which type of welding equipment the part is dedicated, such as "dedicated to arc welding machines," "for hot spraying equipment." It must be consistent with the scope of heading 8468. Material: Declare the main material of the part, such as copper alloy, stainless steel, ceramics, etc. Material affects classification, as certain ceramic parts may be classified under Chapter 69. Brand: Declare the brand of the part (if any); if no brand, fill in "no brand." The brand helps confirm the source of the part and the applicable equipment. Model: Declare the model of the part, which should be consistent with the actual item. The model helps identify the specific purpose of the part. Applicable Equipment Model: Declare the model of the welding equipment to which the part applies, proving its dedication. For example, "suitable for Panasonic YD-350GR welding machine." Whether Dedicated Part: Clearly declare whether it is a dedicated part, that is, whether it is used only for equipment under heading 8468. Answer "yes" or "no." Product Name: Contact tip for arc welding machine; Purpose: Dedicated to arc welding machine; Material: Copper alloy; Brand: Panasonic; Model: TET-02015; Applicable Equipment Model: Panasonic YD-350GR; Whether Dedicated Part: Yes. Incorrectly classifying general parts (such as bolts, nuts) under 846890; they should be classified under 7318. Incorrectly classifying electrical parts (such as electrodes, cables) under 846890; they should be classified under 8515 or 8544. Failure to declare dedication, leading to classification under other headings (such as 8466 general parts).

The core criteria for classification are: 1) whether the part is dedicated to welding equipment or hot spraying equipment listed under heading 8468; 2) whether the part is an electrical part (such as parts of electrical welding equipment of 8515); 3) whether the part has an independent function (such as an independently operated wire feeder, which should be classified under 8468, not as a part). According to General Rules of Interpretation 1 and 6, 846890 applies only to dedicated parts of equipment under heading 8468 and that are not electrically heated. If the part is a dedicated part of electrical welding equipment (8515), it should be classified under 8515. If the part is a general part, it is classified according to material. 851590 Parts of electrical welding equipment: 851590 covers dedicated parts of heading 8515 (electrical welding equipment), such as welding tongs, electrodes, etc. 846890 covers parts of non-electrically heated welding equipment. The key difference lies in whether the welding equipment is electrically heated (8515) or non-electrical (8468). 846693 Machine tool parts: 846693 is dedicated parts of machine tools of 8456-8461. If welding equipment is used for cutting (such as laser cutting machines), its parts may be classified under 846693. 846890 is only for welding or hot spraying equipment. 846791 Chain saw parts: 846791 is parts of hand-held tools of 8467 (such as chain saws). If the welding equipment is hand-held, could its parts be classified under 846791? However, 8468 explicitly includes hand-held welding equipment, so its parts are still classified under 846890. Note that 8467 does not include welding equipment. 854390 Parts of electrical equipment: 854390 is parts of heading 8543 (electrical equipment with independent functions). If a welding equipment part has an independent electrical function, it may be classified under 854390. However, 846890 takes precedence for dedicated parts of welding equipment. 732690 Articles of iron or steel: 732690 covers other articles of iron or steel. If a welding equipment part is a general iron or steel article (such as a bracket) and is not dedicated, it should be classified under 732690. 846890 requires dedication. Is the part dedicated to welding equipment of 8468? Does it belong to parts of electrical welding equipment (8515)? Does the part have an independent function? Does the material affect classification (such as ceramics, plastics)? Is it a general part (such as bolts, nuts)?

What is the difference between 846890 and 851590? 846890 is parts of welding equipment (non-electrically heated), such as parts of arc welding machines and hot spraying equipment; 851590 is parts of electrical welding equipment (such as resistance welding machines, laser welding machines). The key difference lies in whether the welding equipment belongs to heading 8515. If the equipment uses electrical heating, its parts are classified under 851590; otherwise under 846890. How to determine whether a welding equipment part is dedicated? Dedication means the part is used only for equipment under heading 8468 and cannot be used for other equipment. For example, a welding torch nozzle is dedicated to arc welding machines and is a dedicated part; bolts and nuts can be used for various equipment and are general parts. When declaring, it is necessary to provide the applicable equipment model, purpose, and other evidence. Is material important when classifying welding equipment parts? Material is an important factor. For example, ceramic nozzles may be classified under Chapter 69, and plastic parts may be classified under Chapter 39, unless they are dedicated to 8468 equipment and meet the heading text. However, according to classification rules, if a part is dedicated to 8468 equipment, it may still be classified under 846890 even if the material is different. Judgment must combine material and dedication. How are parts of 846890 classified if used for cutting equipment? If the part is used for cutting equipment (such as laser cutting machines), it does not belong to 8468, because 8468 only covers welding and hot spraying equipment. Parts of cutting equipment are usually classified under 846693 as parts of 8456 (laser cutting machines), or under other headings according to the type of equipment. Are parts of hot spraying equipment classified under 846890? Yes, heading 8468 explicitly includes machines and apparatus for hot spraying, so their dedicated parts are classified under 846890. Hot spraying equipment includes flame spraying, plasma spraying, etc., but note that electrically heated plasma spraying equipment may be classified under 8515, with its parts under 851590. What should be noted when declaring parts of 846890? When declaring, it is necessary to provide elements such as product name, purpose, material, brand, model, applicable equipment model, and whether it is a dedicated part. The focus is to prove dedication and avoid confusion with general parts. At the same time, attention should be paid to distinguishing electrical and non-electrical welding equipment to prevent classification errors. If welding equipment parts are imported, how to check the tariff rate? The tariff rate must be checked according to the customs tariff of the importing country and may change. It is recommended to check the latest tariff rate through the customs official website or professional databases. Generally, information such as HS code, country of origin, and trade agreements must be provided. Note that 846890 may apply different rates, such as most-favored-nation rate, agreement rate, etc. If parts of 846890 have electrical connectors, are they classified under 8515? Not necessarily. If the main body of the part is dedicated to 8468 equipment, even if it has electrical connectors, it is still classified under 846890. But if the part is a dedicated part of electrical welding equipment (such as welding tongs), it is classified under 851590. The key depends on the type of equipment, not whether the part is electrified.
