Chapter 85 covers electric motors, electrical equipment and their parts; sound recorders and reproducers, television image and sound recorders and reproducers, and parts and accessories thereof. This chapter has an extremely broad scope, covering everything from household appliances to industrial electrical equipment, but excludes certain specific electrical products (such as machinery of Chapter 84, optical instruments of Chapter 90, etc.). The core characteristic is that the goods' primary function depends on electrical energy or electromagnetic principles for operation. Heading 8502 covers generating sets and rotary converters. Specifically includes: generating sets consisting of a generator and an internal combustion engine (diesel, gasoline, etc.), wind-powered generating sets, solar-powered generating sets (except those combining photovoltaic inverters with generators), and rotary converters (such as motor-generators). However, excludes: pumps driven solely by electric motors (classified under 8413), internal combustion engines themselves (classified under 8407/8408), and static converters (classified under 8504). First 2 digits 85: indicates Chapter 85 (electric motors, electrical equipment). Digits 3-4, 02: indicates heading 8502 (generating sets and rotary converters). Digits 5-6, 11: indicates subheading 8502.11, namely 'Generating sets with compression-ignition internal combustion piston engines (diesel or semi-diesel engines) of an output not exceeding 75 kVA'. Digit-by-digit breakdown: 85 (chapter) → 02 (heading) → 11 (subheading). Note that the 5th digit '1' represents compression-ignition internal combustion engine generating sets, and the 6th digit '1' represents power ≤75kVA. If power >75kVA but ≤375kVA, it would be 8502.12, and so on. This commodity is a diesel generating set, whose core characteristics are a compression-ignition internal combustion engine (diesel engine) driving a generator, with a rated output power ≤75kVA. Therefore, it is classified under 8502.11. If power >75kVA, it would be classified under 8502.12 or 8502.13; if driven by a gasoline engine, it would be classified under 8502.20; if wind-driven, it would be classified under 8502.31; if it is a static converter (such as a UPS), it would be classified under 8504.

Product Name: The Chinese and English names of the declared commodity, which should accurately reflect the product attributes, such as '柴油发电机组' or 'Diesel generator set'. Use: Describe the main application scenarios of the generating set, such as backup power, primary power, mobile power, emergency power supply, etc. Brand: Fill in the manufacturer or brand name; if no brand, fill in 'no brand'. Model: Fill in the model code assigned by the manufacturer to distinguish different specifications. Output Power: Must specify the rated output power and unit (kVA or kW) to determine the subheading. Engine Type: Specify whether it is a compression-ignition internal combustion engine (diesel) or a spark-ignition internal combustion engine (gasoline). Generator Type: Specify whether it is an AC generator or a DC generator; usually it is an AC synchronous generator. Complete Set of Parts or Finished Product: Declare the status as finished product or parts, which affects classification and valuation. Customs declaration example: Product Name: Diesel generator set Use: Backup power Brand: Cummins Model: C75D5 Output Power: 75kVA Engine Type: Compression-ignition internal combustion engine (diesel) Generator Type: AC synchronous generator Complete Set of Parts or Finished Product: Finished product Specifications: 75kVA/60Hz/400V Declaration Elements: 1. Product Name; 2. Use; 3. Brand; 4. Model; 5. Output Power; 6. Engine Type; 7. Generator Type; 8. Finished product Output power unit mistakenly filled as kW, while kVA and kW differ by power factor, which may lead to subheading error. Mistakenly reporting a diesel engine-driven generating set as gasoline engine-driven, incorrectly classified under 8502.20. Ignoring the power upper limit of 75kVA, actually power >75kVA but still declared as 8502.11. Brand and model filled inconsistently, leading customs to question the authenticity of documents.

Core basis for classification: 1) The commodity is a generating set, i.e., composed of a generator and an internal combustion engine; 2) The internal combustion engine is compression-ignition (diesel); 3) Rated output power ≤75kVA. Also need to exclude: generating equipment driven solely by electric motors (such as motor-generators, classified under 8502.40), static converters (8504), wind-powered generating sets (8502.31), and internal combustion engines themselves (8408). If the generating set is presented together with the internal combustion engine, and the internal combustion engine is clearly dedicated to the generating set, the whole is classified under 8502. 8502.12 Diesel generating sets (75kVA < power ≤375kVA): The core difference from 8502.11 is the output power range. 8502.11 is ≤75kVA, 8502.12 is >75kVA and ≤375kVA. Power is the only distinguishing criterion, and the rated power must be accurately provided. 8502.20 Spark-ignition internal combustion engine generating sets: 8502.20 is generating sets driven by spark-ignition internal combustion engines such as gasoline engines, while 8502.11 is compression-ignition (diesel). Engine type is the fundamental difference, and judgment must be based on the engine's working principle. 8502.31 Wind-powered generating sets: 8502.31 is wind-driven, belonging to renewable energy power generation, completely different from diesel generating sets in terms of power source. Diesel generating sets rely on fossil fuels. 8504.40 Static converters: 8504.40 is static converters (such as UPS, inverters) with no rotating parts; while 8502.11 includes rotating generators and internal combustion engines. If the commodity is a combination of an inverter and a diesel engine, classification should be determined by the primary function. 8408.90 Parts of compression-ignition internal combustion engines: 8408.90 is parts of diesel engines, while 8502.11 is a complete generating set. If a diesel engine is declared separately, it should be classified under 8408; if declared together with a generator, it is classified under 8502. Is it confirmed that the engine is compression-ignition (diesel)? Is the rated output power ≤75kVA? Does it include both a generator and an internal combustion engine, constituting a complete generating set? Have static converters or wind power generation been excluded? Are the declaration elements such as brand, model, and power consistent?

How to check the import tax rate for 850211? You can check the MFN rate, general rate, VAT rate, and consumption tax by entering HS code 850211 on the General Administration of Customs website, China International Trade Single Window, or third-party query platforms. Note that tax rates are subject to policy adjustments, and the latest published rates should prevail. How are diesel generating sets and gasoline generating sets distinguished in HS codes? Diesel generating sets (compression-ignition) are classified under 8502.11-8502.13, subdivided by power; gasoline generating sets (spark-ignition) are classified under 8502.20. The key distinction lies in the engine ignition method: diesel engines are compression-ignition, gasoline engines are spark-ignition. Which code should a diesel generating set with an output power of 75kVA be classified under? If the rated power is exactly 75kVA, it should be classified under 8502.11 (≤75kVA). If it exceeds 75kVA, it should be classified under 8502.12. Note that the power unit must be kVA; if it is kW, conversion is needed (kVA = kW / power factor). What are the customs declaration elements for diesel generating sets? The main declaration elements include: Product Name, Use, Brand, Model, Output Power, Engine Type, Generator Type, Complete Set of Parts or Finished Product. Some customs offices may require specifications, place of origin, etc. What are the special requirements for importing used diesel generating sets? The import of used mechanical and electrical products must comply with national regulations on the import of mechanical and electrical products, and may require pre-shipment inspection, import licenses, etc. At the same time, environmental protection and energy consumption standards must be observed, and the import of obsolete equipment is prohibited. How are diesel generating sets and diesel engine parts distinguished for classification? Complete diesel generating sets are classified under 8502; diesel engines declared separately are classified under 8408; diesel engine parts are classified under 8408.90. If the generating set and diesel engine are declared together and clearly constitute a generating set, the whole is classified under 8502. Are goods under 850211 eligible for export tax rebates? The export tax rebate rate needs to be determined based on the commodity code and the latest policy. Enterprises can check through the electronic tax bureau or the customs export tax rebate system. Generally, mechanical and electrical products enjoy a certain rebate rate, but the specific rate is subject to official publication. How to determine whether a diesel generating set belongs to 850211 rather than 850212? The only criterion is the rated output power. ≤75kVA is classified under 850211, >75kVA and ≤375kVA is classified under 850212. Power certification issued by the manufacturer or nameplate photos must be provided to ensure accurate declaration.
