Chapter 84 is the core chapter in the HS classification system covering mechanical appliances and parts, including power machinery, pumps, fans, refrigeration equipment, packaging machinery, household appliances, etc. Goods in this chapter generally have mechanical motion characteristics or energy conversion functions, but attention must be paid to distinguishing them from electrical equipment in Chapter 85. Heading 8418 is located in this chapter and specifically refers to refrigerating and freezing equipment, reflecting the independent status of the mechanical refrigeration principle in trade classification. Heading 8418 covers refrigerators, freezers, combined refrigerator-freezers, and other refrigerating equipment, including compression-type, absorption-type, and other types. This heading includes not only household refrigerators but also commercial display cabinets, cold storage units, etc. The key distinguishing point is whether the equipment has active refrigeration function and is usually electrically driven. Under 8418, items are subdivided by volume, use, whether combined, etc. 841810 specifically refers to combined refrigerator-freezers with a capacity exceeding 500 liters. Code 841810 has 6 digits: the first 2 digits "84" represent Chapter 84 (mechanical appliances and parts); digits 3-4 "18" represent heading 8418 (refrigerators, freezers and other refrigerating equipment); digits 5-6 "10" represent subheading 841810, i.e., combined refrigerator-freezers with a capacity exceeding 500 liters. Here "combined" refers to equipment that has both refrigerating and freezing functions, usually with separate compartments; "capacity exceeding 500 liters" means the total effective volume (sum of all compartments) is greater than 500 liters. This subheading is not further subdivided, but attention must be paid to distinguishing it from subheadings such as 8418.21 (compression-type household refrigerators) and 8418.30 (upright freezers). This product is classified under 841810 because it simultaneously meets three conditions: first, it is a combined refrigerator-freezer, i.e., it has both refrigerating and freezing functions; second, its total capacity exceeds 500 liters; third, it uses mechanical refrigeration. Adjacent codes such as 8418.21 refer only to compression-type household refrigerators, usually with smaller capacity and no separate freezer compartment; 8418.30 refers to upright freezers with only freezing function; 8418.40 refers to refrigerated display cabinets with no freezing function. Therefore, capacity and functional combination are the key factors determining classification under 841810.

Product Name: The standard name of the declared goods, which should reflect "combined refrigerator-freezer" and the capacity range, such as "620-liter combined refrigerator-freezer." Brand Type: Fill in the brand name or "no brand," such as "Haier," "Siemens," etc., used for customs intellectual property recordation verification. Export Preference Status: Fill in according to whether a preferential certificate of origin such as an FTA is applied for, such as "enjoying agreement rate" or "not enjoying." Capacity: Declare the total effective capacity in liters, and clearly state whether it exceeds 500 liters, such as "total capacity 620 liters." Refrigeration Method: Explain the refrigeration principle, such as "compression-type" or "absorption-type," usually compression-type. Use: Fill in "household" or "commercial," which affects classification and regulatory conditions. Specifications and Model: Fill in product model, dimensions, power, and other parameters, such as "BCD-620W, width 900mm, power 200W." Whether Equipped with Independent Freezer Compartment: Confirm whether it has an independent freezer compartment, which is an important feature of a combined unit. Product Name: 620-liter combined refrigerator-freezer; Brand Type: Haier; Export Preference Status: not enjoying; Capacity: total capacity 620 liters (refrigerator compartment 400 liters, freezer compartment 220 liters); Refrigeration Method: compression-type; Use: household; Specifications and Model: BCD-620W, width 900mm, height 1800mm, power 200W; Whether Equipped with Independent Freezer Compartment: yes. Capacity calculation error: calculating only a single compartment capacity without combining the total capacity, resulting in classification under other subheadings. Inaccurate function description: mistakenly reporting a freezer-only or refrigerator-only device as a combined unit, causing classification disputes. Confusing brand with model: filling the model in the brand column, affecting intellectual property verification and subsequent audits.

The core criteria for classification are: 1) whether the product is a combined refrigerator-freezer, i.e., it has both refrigerating and freezing functions and usually has independent compartments; 2) whether the total effective capacity exceeds 500 liters; 3) whether mechanical refrigeration is used. Note that capacity should be calculated according to customs-accepted methods, usually the sum of the volumes of all compartments. If the capacity does not exceed 500 liters, it should be classified under a subheading other than 8418.10, such as 8418.21 (compression-type household refrigerators). In addition, use (household/commercial) does not affect classification under 841810, but may affect regulatory conditions. 841810 Combined refrigerator-freezers with a capacity exceeding 500 liters: Current code, requiring capacity >500 liters and being a combined unit. 841821 Compression-type household refrigerators: Usually capacity ≤500 liters, and may have no independent freezer compartment, or weaker freezing capability. 841830 Upright freezers (capacity ≤800 liters): Only has freezing function, no refrigerator compartment, and different capacity limit. 841840 Upright freezers (capacity >800 liters): Only freezing function, capacity exceeds 800 liters, different function from combined units. 841850 Refrigerated display cabinets: Only refrigerating function, usually used for commercial display, no freezer compartment. Does it have both refrigerating and freezing functions? Does the total capacity exceed 500 liters? Does it use mechanical refrigeration (compression-type or absorption-type)? Have the volumes of all compartments been combined for calculation? Do the brand and model match the actual product?

How can I check the import tariff rate for 841810? You can use the General Administration of Customs website, China International Trade Single Window, or third-party query platforms, enter HS code 841810, select the country of origin and trade mode, and obtain the MFN rate, agreement rate, etc. Note that rates may be adjusted, and it is recommended to use the latest data at the time of declaration. Which code should a 500-liter combined refrigerator-freezer be classified under? If the capacity is exactly 500 liters, it does not meet the condition of "exceeding 500 liters" and should be classified under a subheading other than 8418.10, such as 8418.21 (compression-type household refrigerators) or 8418.29 (other household refrigerators), depending on the refrigeration method and use. What certifications are required for 841810 products exported to the EU? Usually CE certification (Low Voltage Directive, EMC Directive), energy efficiency label (ERP Directive), and RoHS compliance are required. The specifics depend on product specifications and EU member state requirements; it is recommended to confirm with the importer in advance. How should capacity be calculated for customs declaration? Capacity should be the sum of the effective volumes of all compartments, usually in liters, declared according to the manufacturer's technical parameters or measured data. Customs may require a test report, so accuracy of the data must be ensured. What is the main difference between 841810 and 841821? 841810 requires a capacity exceeding 500 liters and being a combined refrigerator-freezer; 841821 is a compression-type household refrigerator, usually with capacity not exceeding 500 liters and possibly no independent freezer compartment. There is a clear boundary between the two in terms of capacity and functional combination. What should be noted when selling 841810 products via cross-border e-commerce? It is necessary to confirm that the product complies with the destination country's energy efficiency and safety standards and to correctly declare the HS code. Small parcel exports may be eligible for simplified declaration, but bulk trade requires formal customs declaration. It is recommended to retain product technical documentation for inspection. If a combined unit has a capacity exceeding 500 liters but a very small freezer compartment, is it still classified under 841810? As long as it has an independent freezing function and the total capacity exceeds 500 liters, it should be classified under 841810; the size of the freezer compartment does not affect classification. However, if the freezer compartment can only make ice or the temperature does not meet freezing standards, it may be determined to be a refrigerator, and careful judgment is required. Does exporting products under 841810 require an export license? Usually not required, but if dual-use items or destination country sanctions are involved, a license may be required. It is recommended to check the latest Catalog of Goods Subject to Export License Administration and customs regulatory conditions, or consult a professional customs broker.
