Chapter 84 is a core chapter in the HS classification system, covering various machines, mechanical appliances and their parts, including power machinery, agricultural machinery, metalworking machine tools, office equipment, refrigeration equipment, etc. Goods in this chapter generally have mechanical motion or energy conversion functions, but goods such as electrical power generation and electronic components classified in other chapters must be excluded. Freezers, as heat exchange equipment that uses compressors for refrigeration, are typical mechanical appliances and are therefore classified in Chapter 84. Heading 8418 covers refrigerators, freezers and other refrigerating equipment, including compression-type, absorption-type and other types, as well as heat pumps. This heading includes not only household refrigerators and freezers, but also commercial refrigerated display cabinets, ice makers, etc. However, it should be noted that air conditioners are classified under 8415, while 8418 mainly covers standalone refrigerating equipment whose core function is to maintain a low-temperature environment rather than regulate space temperature. Code 841830 is a six-digit subheading. The first 2 digits, 84, indicate Chapter 84 (machines, mechanical appliances). Digits 3-4, 18, indicate heading 8418 (refrigerators, freezers and other refrigerating equipment). Digits 5-6, 30, indicate subheading 841830, specifically freezers with a capacity not exceeding 250 liters. Here, freezer refers to a cabinet capable of lowering the temperature of items below zero and maintaining it, usually upright or chest type, using compressor refrigeration. Capacity refers to the internal effective storage space, measured in liters, with 250 liters as the dividing point; if exceeded, classification falls under 841840. This product is a freezer with a capacity not exceeding 250 liters, meeting the description of subheading 841830. The difference from adjacent code 841810 (combined refrigerator-freezers) is that 841830 has only freezing function and no refrigerator compartment; the difference from 841840 (freezers with a capacity exceeding 250 liters) is capacity size; the difference from 841850 (other refrigerating or freezing equipment) is that 841830 is a standalone cabinet dedicated to freezing, rather than a display cabinet or other type.

Product name: The standard name of the declared commodity should accurately reflect the product attributes, such as "freezer" or "chest freezer", and avoid confusing terms such as "refrigerator". Brand: Fill in the product brand, such as "Haier", "Xingxing", etc.; if there is no brand, fill in "unbranded". Brand affects price and origin, but is not a classification factor. Model: Fill in the model provided by the manufacturer, such as "BD-100", to distinguish specific specifications. The model helps confirm capacity and function. Capacity: Declare the internal effective capacity of the freezer in liters (L), and it must not exceed 250 liters. Capacity is the key element for classification under 841830. Refrigeration method: Explain the refrigeration principle, such as "compression type", "absorption type", etc. Compression type is the most common, but absorption type may also be classified under 8418. Use: Fill in the product use scenario, such as "household", "commercial". Use affects classification; for example, medical freezers may be classified under 8418 but special regulations should be noted. Power: Fill in the rated input power in watts (W). Power affects energy efficiency and tax rates, but is not a classification factor. Origin: Fill in the country of production, such as "China". Origin affects tariffs and trade agreements and must be consistent with brand and model. Product name: freezer; Brand: Haier; Model: BD-100; Capacity: 100 liters; Refrigeration method: compression type; Use: household; Power: 80W; Origin: China. Incorrect capacity declaration: misreporting external dimensions or gross volume as effective capacity, resulting in exceeding 250 liters and incorrect classification under 841840. Function confusion: misreporting a freezer with refrigeration function as 841830, when it should actually be classified under 841810 (combined refrigerator-freezers). Failure to declare refrigeration method: not declaring compression type or absorption type, which may affect customs judgment on classification.

The core criteria for classification are: 1. Whether the product is a freezer, that is, it has only freezing function and can lower the temperature of items below zero; 2. Whether the capacity does not exceed 250 liters, where capacity refers to internal effective storage space, usually measured in liters; 3. Whether it is a standalone cabinet rather than a display cabinet or large cold storage equipment. If the above conditions are met, it is classified under 841830. If the capacity exceeds 250 liters, it is classified under 841840; if it has both refrigeration and freezing functions, it is classified under 841810; if it is other refrigerating equipment, it is classified under 841850. 841810 Combined refrigerator-freezers: 841810 is a combined appliance with both refrigeration and freezing functions, usually with separate refrigerator and freezer compartments; 841830 is only a freezer with no refrigeration function. 841840 Freezers with a capacity exceeding 250 liters: 841840 has the same function as 841830, but capacity exceeds 250 liters. Capacity is the only distinguishing standard and must be measured accurately. 841850 Other refrigerating or freezing equipment: 841850 includes refrigerated display cabinets, cold storage equipment, etc., usually large commercial equipment, while 841830 is a standalone freezer with smaller capacity. 841869 Other refrigerating equipment: 841869 covers other unspecified refrigerating equipment under heading 8418, such as ice makers and beverage coolers, which do not have the cabinet characteristics of a freezer. 841821 Compression-type household refrigerators: 841821 is a compression-type refrigerator with only refrigeration function, usually at 0-10°C, while 841830 is a freezer with a temperature below 0°C. Confirm that the product has only freezing function and no refrigerator compartment. Accurately measure the internal effective capacity to ensure it does not exceed 250 liters. Check whether the refrigeration method is compression type or absorption type. Confirm whether it is a standalone cabinet, not a display cabinet or cold storage equipment. Check whether the declaration elements are complete, especially capacity and use.

How can I check the tariff rate for 841830? The tariff rate must be determined based on origin and trade agreements. It can be checked through the General Administration of Customs website, China International Trade Single Window, or by consulting a customs broker. Note that rates may change, and the latest tariff schedule shall prevail at the time of declaration. Should a freezer with a capacity of 250 liters be classified under 841830 or 841840? Subheading 841830 explicitly states "capacity not exceeding 250 liters", so 250 liters and below are classified under 841830, and above 250 liters under 841840. The internal effective capacity must be measured accurately to avoid errors. Is there a difference in classification between household freezers and commercial freezers? Classification is mainly based on capacity and function, not use. As long as the capacity does not exceed 250 liters and it has only freezing function, whether household or commercial, it is classified under 841830. However, large commercial equipment may be classified under other subheadings due to different capacity or function. How should a freezer with refrigeration function be classified? If it has both refrigeration and freezing functions, it should be classified under 841810 (combined refrigerator-freezers). 841830 applies only to cabinets with a single freezing function. What unit should be used for capacity in declaration? The capacity unit should be "liter" (L). If the product is marked in cubic feet, it must be converted to liters (1 cubic foot ≈ 28.316 liters). The unit must be clearly stated in the declaration elements to avoid customs doubts. Can imported used freezers be classified under 841830? Used freezers can still be classified under 841830 if they meet the capacity and function conditions. However, note that used mechanical and electrical products may involve additional requirements such as import licenses and inspection and quarantine; it is advisable to consult customs in advance. What is the main difference between 841830 and 841850? 841830 is a standalone freezer with a capacity not exceeding 250 liters; 841850 is other refrigerating or freezing equipment, such as refrigerated display cabinets and cold storage, usually with larger capacity or different structure. The key difference lies in whether it is a standalone cabinet and its capacity. If the freezer capacity is exactly 250 liters, how can classification disputes be avoided? It is recommended to provide detailed technical specifications or test reports at the time of declaration to prove that the internal effective capacity does not exceed 250 liters. At the same time, explain the measurement method in the remarks column of the customs declaration form for customs verification.
