Chapter 84 is the core chapter in the HS classification covering mechanical equipment and parts, including power machinery, pumps, fans, air conditioning equipment, refrigeration equipment, etc. Goods in this chapter usually have mechanical motion characteristics or energy conversion functions, but exclude electrical equipment (Chapter 85) and vehicles (Chapter 87). Evaporative air coolers, as mechanical devices that use the principle of water evaporation and heat absorption for cooling, fall within the scope of this chapter. Heading 8479 covers machines and mechanical appliances having individual functions, not specified or included elsewhere in this chapter. This heading is a "residual" heading applicable to mechanical equipment that cannot be classified under specific headings such as 8471 to 8478. Evaporative air coolers, because they do not contain a refrigeration unit (compression-type refrigeration), are not classified under 8415 air conditioning machines, nor under 8414 fans, and are therefore classified under 8479. First 2 digits 84: indicates Chapter 84, covering mechanical equipment and parts. Digits 3-4, 79: indicates heading 8479, i.e., "machines and mechanical appliances having individual functions, not specified or included elsewhere in this chapter." Digits 5-6, 60: indicates subheading 847960, specifically "evaporative air coolers." This subheading specifically targets equipment that uses the principle of water evaporation and heat absorption to cool air, distinguishing it from other air conditioning devices. Evaporative air coolers do not contain a compression-type refrigeration system, so they are not classified under 8415 air conditioning machines; they are also not merely fans, but achieve cooling through water evaporation, so they are not classified under 8414. Because their function is individual and they are not specified or included elsewhere, they are classified under 8479, and further under the specific subheading 847960.

Heading
Heading 8479 covers machines and mechanical appliances having individual functions, not specified or included elsewhere in this chapter. This heading is a "residual" heading applicable to mechanical equipment that cannot be classified under specific headings such as 8471 to 8478. Evaporative air coolers, because they do not contain a refrigeration unit (compression-type refrigeration), are not classified under 8415 air conditioning machines, nor under 8414 fans, and are therefore classified under 8479.
Digit Breakdown
First 2 digits 84: indicates Chapter 84, covering mechanical equipment and parts. Digits 3-4, 79: indicates heading 8479, i.e., "machines and mechanical appliances having individual functions, not specified or included elsewhere in this chapter." Digits 5-6, 60: indicates subheading 847960, specifically "evaporative air coolers." This subheading specifically targets equipment that uses the principle of water evaporation and heat absorption to cool air, distinguishing it from other air conditioning devices.
Classification Basis
Evaporative air coolers do not contain a compression-type refrigeration system, so they are not classified under 8415 air conditioning machines; they are also not merely fans, but achieve cooling through water evaporation, so they are not classified under 8414. Because their function is individual and they are not specified or included elsewhere, they are classified under 8479, and further under the specific subheading 847960.

Ignoring the "Whether It Has a Refrigeration Device" element, failing to clearly declare no compressor refrigeration.
Power or air volume filled in inaccurately, inconsistent with product technical parameters.
🎯 Classification Logic
The core basis for classification is the product's cooling principle: evaporative air coolers use water evaporation to absorb latent heat to cool air and do not contain a compression-type refrigeration system. According to General Rules of Interpretation 1 and 6, the goods conform to the description of 8479 "machines not specified or included elsewhere," and subheading 847960 explicitly names "evaporative air coolers," so they should be classified under this code. 8415 Air Conditioning Machines: 8415 includes air conditioning machines with compression-type refrigeration (heat pumps) that can actively cool and dehumidify; evaporative coolers rely solely on water evaporation for cooling, have no compressor, and are therefore not classified under 8415. 8414 Fans: 8414 covers fans for simple ventilation or air exchange, without cooling function; evaporative coolers achieve cooling through water evaporation, exceeding the function of fans, and are therefore not classified under 8414. 8479 Other Machines: 8479 is a residual heading, but 847960 is a specific subheading and should be given priority for classification under 847960. 8418 Refrigeration Equipment: 8418 covers compression-type refrigeration equipment (such as refrigerators, freezers) used for cold storage and freezing; evaporative coolers are used for air cooling, not cold storage, and are therefore not classified under 8418. Does it not contain a compression-type refrigeration system? Does it use the principle of water evaporation and heat absorption? Is it used for air cooling rather than cold storage? Is it not specifically named under other headings? Does it meet the description of subheading 847960?

Confused Codes：
8415 - Air Conditioning Machines
8415 includes air conditioning machines with compression-type refrigeration (heat pumps) that can actively cool and dehumidify; evaporative coolers rely solely on water evaporation for cooling, have no compressor, and are therefore not classified under 8415.
8414 - Fans
8414 covers fans for simple ventilation or air exchange, without cooling function; evaporative coolers achieve cooling through water evaporation, exceeding the function of fans, and are therefore not classified under 8414.
8479 - Other Machines
8479 is a residual heading, but 847960 is a specific subheading and should be given priority for classification under 847960.
8418 - Refrigeration Equipment
8418 covers compression-type refrigeration equipment (such as refrigerators, freezers) used for cold storage and freezing; evaporative coolers are used for air cooling, not cold storage, and are therefore not classified under 8418.

❓ FAQ
What is the difference in HS classification between evaporative air coolers and ordinary air conditioners? Ordinary air conditioners usually contain a compression-type refrigeration system and are classified under 8415; evaporative air coolers have no compressor and rely on water evaporation for cooling, and are classified under 847960. How can I check the import tariff rate for 847960? You can visit the official website of the General Administration of Customs of China or use the "Customs Classification Intelligent Navigation" system, enter HS code 847960 to check the latest tariff rate, or consult a professional customs broker. How should "Whether It Has a Refrigeration Device" be filled in during declaration? If the product has no compression-type refrigeration system, fill in "No"; if it does, it may be classified under 8415, and the code needs to be reconfirmed. What certifications are required for exporting evaporative air coolers? Exports generally need to comply with destination country standards, such as EU CE, US UL, etc. Specific requirements should be handled according to customer requirements and local regulations. What is the difference between 847960 and 847989? 847960 is the specific subheading for evaporative air coolers; 847989 is for other machines not elsewhere specified under 8479. If a product meets the description of 847960, it should be classified under 847960 first. If an evaporative cooler has a humidifying function, will it affect classification? If humidification is an auxiliary function and the main function is still evaporative cooling, it does not affect classification under 847960; if the main function becomes humidification, it may be classified under other subheadings of 8479. What should be noted when filling in brand and model during customs declaration? Brand and model should be filled in truthfully, consistent with the actual product and documents, to avoid customs clearance delays or penalties due to inaccurate declaration. Are the power and air volume of evaporative air coolers required to be declared? Yes, power and air volume are important technical parameters that help customs confirm the product's attributes and classification, and should be declared accurately.
