Chapter 85 covers electric motors, electrical equipment and parts thereof; sound recorders and reproducers, television image and sound recorders and reproducers, and parts and accessories thereof. This chapter is one of the most technology-intensive chapters in the HS classification, covering a wide range of products from household appliances to industrial electronic equipment. The core characteristic is that goods must operate by electrical energy or be parts of electrical apparatus, but it should be noted that this chapter excludes certain specific electrical products (such as mechanical apparatus of Chapter 84, optical instruments of Chapter 90, etc.). Heading 8515 covers welding machines and apparatus, including arc welding, resistance welding, laser welding, electron beam welding, plasma arc welding and other types of welding equipment, as well as apparatus for hot spraying of metals or metal carbides. However, this heading does not include welding materials such as manual welding electrodes and welding wire (classified in Chapter 83 or Chapter 71), nor does it include machines used solely for cutting (if welding is the primary function, they remain classified in this heading). First 2 digits 85 = Chapter 85 (electric motors, electrical equipment and parts thereof); digits 3-4: 15 = heading 8515 (welding machines and apparatus); digits 5-6: 29 = subheading 851529, specifically "other resistance welding machines". Under 8515, 851511 covers brazing or soldering machines, 851519 covers other brazing or soldering machines, 851521 covers fully or partly automatic resistance welding machines, 851529 covers other resistance welding machines, 851531 covers fully or partly automatic arc welding machines, 851539 covers other arc welding machines, and 851580 covers other welding machines and apparatus. Therefore, 851529 specifically refers to resistance welding machines other than fully or partly automatic resistance welding machines. This commodity is a resistance welding machine and is not fully or partly automatic, so it is classified under 851529. If it were a fully or partly automatic resistance welding machine, it would be classified under 851521; if it were an arc welding machine, it would be classified under 851531 or 851539; if it were laser welding, electron beam welding, etc., it would be classified under 851580. Attention should be paid to distinguishing it from other subheadings of 8515, with the core being the welding principle (resistance welding) and the degree of automation (non-fully/partly automatic).

Product Name: The Chinese and foreign language names of the declared commodity, which should accurately reflect the welding principle and machine type, such as "resistance welding machine (non-fully automatic)". Brand Type: Fill in the brand name or logo; if no brand, fill in "no brand"; must be consistent with the actual product. Export Preference Status: Select "export goods enjoy preferential tariffs in the final destination country" or "do not enjoy" based on actual trade conditions, and fill in the corresponding agreement code. Use: Explain the application field of the welding machine, such as "used for automobile body welding", "used for metal product processing", etc. Working Principle: Indicate the welding principle, such as "resistance welding", "arc welding", "laser welding", etc., which must be consistent with the classification. Degree of Automation: Specify whether it is fully automatic, partly automatic, or manual; resistance welding machines need to distinguish between fully/partly automatic and others. Power: Fill in the rated power of the welding machine, usually in kilowatts (kW) or kilovolt-amperes (kVA). Model: Fill in the model designated by the manufacturer to identify specific specifications. Product Name: resistance welding machine (non-fully automatic); Brand Type: no brand; Export Preference Status: do not enjoy; Use: used for metal cabinet welding; Working Principle: resistance welding; Degree of Automation: manual; Power: 50kVA; Model: DN-50. Remarks: This equipment is a stationary resistance welding machine that generates resistance heat at the contact surface of workpieces by applying pressure and current through electrodes to achieve welding, operated non-fully or partly automatically. Failure to distinguish resistance welding from arc welding, leading to subheading errors. Ignoring the degree of automation, incorrectly classifying a non-fully automatic resistance welding machine under 851521. Inaccurate declaration of brand type, such as declaring an OEM machine as no brand. Incorrect power units, such as writing kVA as kW. Use description too broad to assist classification.

The core basis for classification is the welding principle (resistance welding) and the degree of automation (non-fully or partly automatic). According to the Import and Export Tariff, subheadings under 8515 are divided by welding method and degree of automation. Resistance welding machines are further divided into fully or partly automatic (851521) and other (851529). Therefore, if the equipment is resistance welding and non-fully or partly automatic, it is classified under 851529. A comprehensive determination should be made based on product manuals, technical parameters, and operating methods. 851521 Fully or partly automatic resistance welding machines: This code requires the resistance welding machine to have fully or partly automatic functions, while 851529 is non-fully or partly automatic. The key difference lies in whether it has automation features such as automatic feeding and automatic welding cycles. 851531 Fully or partly automatic arc welding machines: Different welding principles: 851531 is arc welding, 851529 is resistance welding. Arc welding uses arc heat, resistance welding uses resistance heat. 851539 Other arc welding machines: Non-fully or partly automatic arc welding machines are classified under 851539, while resistance welding machines are classified under 851529. The difference in principle is the core distinguishing point. 851580 Other welding machines and apparatus: This code covers laser welding, electron beam welding, plasma arc welding and other unlisted welding methods, as well as hot metal spraying apparatus. Resistance welding machines are not classified here. 846880 Other welding machines and apparatus (mechanical): 846880 covers welding machines using mechanical methods (such as friction welding, ultrasonic welding), while 851529 is electrical resistance welding machines. Is the welding principle resistance welding? Does it have fully or partly automatic functions? Is it used for welding rather than cutting or brazing? Are the declaration elements such as brand, model, and power complete? Is it confused with mechanical welding equipment of Chapter 84?

How to determine whether a welding machine belongs to 851529? First confirm that the welding principle is resistance welding, and then confirm that it is non-fully or partly automatic. If both conditions are met, it is classified under 851529. If it is a fully or partly automatic resistance welding machine, it is classified under 851521; if it is arc welding, it is classified under 851531 or 851539. What is the difference between 851529 and 851580? 851529 specifically refers to non-fully or partly automatic resistance welding machines, while 851580 covers other unlisted welding machines and apparatus, such as laser welding, electron beam welding, plasma arc welding, etc. The welding principles are different, and strict distinction is required during classification. What are the consequences of incorrect power declaration? Power is an important reference for customs valuation and classification. Incorrect declaration may lead to classification queries, tax supplements, or administrative penalties. It is recommended to fill in accurately based on the equipment nameplate or technical manual, and pay attention to units (kW or kVA). What are the differences in declaration elements between resistance welding machines and arc welding machines? Resistance welding machines require key declaration of the degree of automation (fully automatic/partly automatic/other), while arc welding machines also need to distinguish the degree of automation. However, their working principles are different, and the declaration must clearly state "resistance welding" or "arc welding" for correct customs classification. If a welding machine has both welding and cutting functions, how should it be classified? Classify according to the primary function. If welding is the primary function, it is classified under 8515; if cutting is the primary function, it may be classified under 8461 or 8462, etc. Function descriptions and technical parameters should be provided, and advance classification may be applied for if necessary. What documents are required for exporting goods under 851529? Generally, contracts, invoices, packing lists, customs declarations, declaration elements, etc. are required. If preferential tariffs are claimed, a certificate of origin is required. In addition, depending on the destination country's requirements, CE certification, quality certificates, etc. may be required. How to check the import tariff rate for 851529? The latest tariff rates can be checked through the official website of the General Administration of Customs of China or the International Trade Single Window. Tariff rates vary by country, trade agreements, and annual adjustments, and the official published rates should prevail. How to distinguish 851529 from 846880 in classification? 846880 covers mechanical welding machines (such as friction welding machines, ultrasonic welding machines), while 851529 covers electrical resistance welding machines. The core difference lies in the source of welding energy: mechanical energy vs. electrical energy.
