Chapter 90 covers optical, photographic, cinematographic, measuring, checking, medical or surgical instruments and apparatus, precision instruments and apparatus; parts and accessories thereof. Goods under this chapter generally feature high technology content and high added value. Classification requires focus on their functional principles, uses, and whether they fall within the exclusion scope of the notes to this chapter. Heading 9016 covers balances with a sensitivity of 50 mg or better, whether or not with weights. This heading specifically refers to high-precision weighing instruments. The core criterion is whether the sensitivity (scale interval) reaches 50 mg or better, regardless of whether weights are provided or whether it is combined with other devices. First 2 digits 90 = Chapter 90 (optical, measuring, medical and other precision instruments); digits 3-4, 16 = heading 9016 (balances with sensitivity ≤ 50 mg); digits 5-6, 00 = subheading, indicating no further subdivision under this heading, and all balances meeting the heading description are classified under this subheading. Therefore, 901600 fully represents 'balances with a sensitivity of 50 mg or better.' Vehicle-mounted precision balances are classified under this code because they have high-precision weighing functions and their sensitivity meets the threshold. Vehicle-mounted precision balances are classified under 901600 because their core function is precision weighing and their sensitivity is typically ≤ 50 mg, meeting the description of heading 9016. They are not classified under 8423 (weighing machinery) because the latter refers to ordinary weighing equipment with sensitivity > 50 mg; they are not classified under 9031 (measuring or checking instruments) because the latter does not specifically target balances.

Heading
Heading 9016 covers balances with a sensitivity of 50 mg or better, whether or not with weights. This heading specifically refers to high-precision weighing instruments. The core criterion is whether the sensitivity (scale interval) reaches 50 mg or better, regardless of whether weights are provided or whether it is combined with other devices.
Digit Breakdown
First 2 digits 90 = Chapter 90 (optical, measuring, medical and other precision instruments); digits 3-4, 16 = heading 9016 (balances with sensitivity ≤ 50 mg); digits 5-6, 00 = subheading, indicating no further subdivision under this heading, and all balances meeting the heading description are classified under this subheading. Therefore, 901600 fully represents 'balances with a sensitivity of 50 mg or better.' Vehicle-mounted precision balances are classified under this code because they have high-precision weighing functions and their sensitivity meets the threshold.
Classification Basis
Vehicle-mounted precision balances are classified under 901600 because their core function is precision weighing and their sensitivity is typically ≤ 50 mg, meeting the description of heading 9016. They are not classified under 8423 (weighing machinery) because the latter refers to ordinary weighing equipment with sensitivity > 50 mg; they are not classified under 9031 (measuring or checking instruments) because the latter does not specifically target balances.
📝 Declaration Elements

Model: Fill in the specific model, such as 'XP205,' 'ME204,' etc., to identify the specific specifications. Sensitivity: Fill in the scale interval (sensitivity) of the balance, which must be ≤ 50 mg, such as '0.01 mg,' '0.1 mg.' Maximum Capacity: Fill in the maximum capacity of the balance, such as '220 g,' '5000 g,' which together with sensitivity determines the precision grade. With or Without Weights: Fill in whether weights are included, such as 'with weights' or 'without weights,' which affects classification completeness. Working Principle: Briefly describe the working principle, such as 'electromagnetic force compensation,' 'strain gauge,' etc., to help determine whether it is a precision balance.

🎯 Classification Logic
The core basis for classification is the notes to Chapter 90 of the Import and Export Tariff and the text of heading 9016. Key determination points: 1. Whether sensitivity is ≤ 50 mg; 2. Whether it is a balance (rather than other weighing devices); 3. Whether it is used for vehicles (vehicle-mounted does not affect classification; it is still classified under 9016 as a precision balance). If sensitivity > 50 mg, it should be classified under 8423; if it is vehicle-specific weighing equipment with sensitivity > 50 mg, it is also classified under 8423. 8423 Weighing Machinery: 8423 covers weighing machinery with sensitivity > 50 mg, including vehicle-mounted weighbridges, price-computing scales, etc.; 9016 is limited to precision balances with sensitivity ≤ 50 mg. 9031 Measuring or Checking Instruments: 9031 covers other measuring and checking instruments, such as coordinate measuring machines; 9016 specifically refers to precision balances with a single function. 9017 Drawing, Calculating and Measuring Instruments: 9017 is used for drawing, calculating, etc., and does not involve weighing; 9016 is used for precision weighing. 9027 Physicochemical Analysis Instruments: 9027 covers analytical instruments such as spectrometers and chromatographs; 9016 refers only to precision balances and does not have analytical functions. Is the sensitivity ≤ 50 mg? Is it a balance rather than other weighing machinery? Is it used for vehicles? Vehicle-mounted does not affect classification. Does it include weights? Including weights does not affect classification. Does it have other instrument functions? If so, it may be excluded.

❓ FAQ
What is the difference in HS codes between vehicle-mounted precision balances and ordinary vehicle-mounted weighing equipment? The core difference lies in sensitivity. Vehicle-mounted precision balances with sensitivity ≤ 50 mg are classified under 901600; vehicle-mounted weighing equipment with sensitivity > 50 mg (such as weighbridges and price-computing scales) are classified under 8423. Sensitivity parameters must be provided at declaration. How can I check the import tariff rate for 901600? It can be checked through the General Administration of Customs official website, China International Trade Single Window, or the Import and Export Tariff. Tariff rates vary by country, trade agreement, and origin of goods. It is recommended to rely on the latest tariff or consult a professional customs broker. What are the consequences of writing the sensitivity unit incorrectly when declaring a vehicle-mounted precision balance? Incorrect units may lead to classification errors. For example, if 0.01 g is mistakenly written as 0.01 mg, the actual sensitivity may be > 50 mg, and it should be classified under 8423 rather than 9016. Incorrect declaration may trigger customs questioning, supplementary duties, or penalties. Are vehicle-mounted precision balances with weights still classified under 901600? Yes. Heading 9016 explicitly includes 'whether or not with weights,' so the inclusion of weights does not affect classification and they remain classified under 901600. However, whether weights are included must be truthfully filled in at declaration. If a vehicle-mounted precision balance also has a data recording function, does that change its classification? If the data recording function is merely auxiliary and does not change the basic function of the balance, it remains classified under 901600. However, if that function makes it a multifunctional instrument, it may be classified according to its principal function. It is recommended to provide a detailed manual. What should be noted when declaring a vehicle-mounted precision balance imported through cross-border e-commerce channels? Detailed declaration elements must be provided, including sensitivity, maximum capacity, brand, and model. Personal use may be subject to postal tax, but if the quantity exceeds the limit or it is for commercial use, it must be declared under general trade and classified under 901600. How can 901600 and 902780 be distinguished for classification? 901600 specifically refers to balances with sensitivity ≤ 50 mg; 902780 covers other physicochemical analysis instruments. If the balance is used only for weighing, it is classified under 9016; if it has analytical functions (such as moisture determination), it may be classified under 9027. What are the key points of customs review for the classification of vehicle-mounted precision balances? The review focuses on sensitivity parameters, working principle, use, and whether weights are included. Enterprises must provide technical manuals, test reports, and other evidence proving sensitivity ≤ 50 mg; otherwise, it may be classified under 8423.
