Chapter 85 covers electrical machinery and equipment and parts thereof; sound recorders and reproducers, television image and sound recorders and reproducers. This chapter includes various electrical devices for generation, conversion, storage, use, communication, signaling, control, etc., as well as electronic components such as capacitors, resistors, semiconductor devices, etc. However, this chapter does not include insulated wires and cables (heading 8544), insulators (heading 8546), etc. Heading 8532 covers fixed, variable or adjustable (pre-set) capacitors. It includes various power capacitors, capacitors for electronic equipment, such as ceramic, electrolytic, paper, plastic film and other fixed capacitors, as well as variable or adjustable capacitors used in tuning, coupling, filtering and other circuits. However, it does not include capacitors specially designed for a particular type of equipment, such as motor starting capacitors (if presented together with the motor, they are classified with the motor). First 2 digits 85: indicates Chapter 85, belonging to electrical machinery and equipment. Digits 3-4: 32 indicates heading 8532, specifically fixed, variable or adjustable capacitors. Digits 5-6: 30 under 8532, subheading 8532.30 represents variable or adjustable capacitors. This subheading is further subdivided into multiple lower subheadings, such as 8532.30.10 (power capacitors) and 8532.30.90 (other), but according to the six-digit HS code principle, 853230 refers to variable or adjustable capacitors. The product is a variable or adjustable capacitor, whose capacitance value can be adjusted within a certain range, used in tuning, coupling and other circuits. It is neither a fixed capacitor (8532.10-8532.29) nor a capacitor of other headings (such as 8532.24 specifically for multilayer ceramic fixed capacitors). Therefore, it is classified under 8532.30, in accordance with the heading text and subheading division.

Product Name: The standard name of the declared commodity, should use standardized Chinese or English name, such as "variable capacitor" or "adjustable capacitor". Brand: Fill in the manufacturer or brand name; if no brand, fill in "no brand". Model: Fill in the specific model or specification code to distinguish different products. Use: Explain the application scenario of the capacitor, such as for radio tuning, communication equipment, etc. Type: Specify whether it is a variable capacitor or an adjustable capacitor (pre-set capacitor), and the dielectric type. Capacitance Range: Fill in the minimum and maximum capacitance, usually in picofarads (pF) or microfarads (μF). Rated Voltage: Fill in the rated working voltage of the capacitor, in volts (V). Is Pre-set: Indicate whether it is a pre-set capacitor (requires tool adjustment), usually fill in "yes" or "no". Product Name: Variable Capacitor; Brand: Murata; Model: TZV2Z060A110R00; Use: For radio tuning circuit; Type: Variable capacitor, air dielectric; Capacitance Range: 5pF-60pF; Rated Voltage: 100V; Is Pre-set: No. Confusing variable capacitors with fixed capacitors, leading to classification under 8532.10 or 8532.24. Not indicating the capacitance range, which may affect customs determination of product characteristics. Use description not specific, such as only writing "used in electronic equipment", which may raise doubts.

The core basis for classification is whether the capacitance value of the capacitor is adjustable. Variable or adjustable capacitors, when used in circuits, have their capacitance value changed by mechanical or electronic means, for tuning, matching, etc. According to HS notes, 8532.30 includes variable capacitors and pre-set capacitors. If the capacitor has a fixed capacitance value, even if slightly adjustable, it should be classified under fixed capacitor subheadings. In addition, it is necessary to confirm whether it is a power capacitor; if used in power systems and adjustable, it is still classified under 8532.30. 8532.10 Fixed capacitors for 50/60Hz circuits: Fixed capacitors are not adjustable, specifically for power frequency circuits, while 8532.30 is adjustable capacitors for high-frequency tuning, etc. 8532.24 Multilayer ceramic fixed capacitors: This code is for fixed capacitors with ceramic dielectric, not adjustable; 8532.30 is adjustable, dielectric not limited. 8532.29 Other fixed capacitors: Other fixed capacitors include paper, plastic, etc., not adjustable; 8532.30 emphasizes adjustability. 8533.40 Variable resistors: Variable resistors are used to adjust resistance value, while 8532.30 is capacitors, adjusting capacitance value. Can the capacitance value be adjusted during use? Is it a pre-set capacitor (requires tool adjustment)? Is it used in power frequency circuits of power systems? Does the dielectric type affect classification? Is it confused with fixed capacitors?

How to determine whether a capacitor is variable or adjustable? Variable capacitors usually refer to capacitors whose capacitance value can be continuously adjusted during use, such as radio tuning capacitors; adjustable capacitors (pre-set) refer to those that need to be adjusted with a tool (such as a screwdriver) and then fixed, generally used for circuit calibration. Both are classified under 8532.30. Does code 853230 include all variable capacitors? Yes, 8532.30 covers all variable or adjustable capacitors, regardless of whether the dielectric is air, ceramic, or plastic. However, note that if the capacitor is combined with specific equipment, it may be classified as a complete machine. How to fill in the capacitance range when declaring? Fill in the minimum and maximum capacitance, such as 5pF-60pF. If it is a fixed value, it does not belong to this code. The unit is usually picofarads (pF) or microfarads (μF), and must be consistent with the actual product. Is there a difference in classification between variable capacitors and trimmer capacitors? In HS codes, both are classified under 8532.30, but the type must be clearly stated when declaring. Trimmer capacitors usually refer to pre-set capacitors that require tool adjustment, while variable capacitors can be adjusted directly by hand. If a variable capacitor is used in a power system, is it still classified under 853230? Yes, as long as the capacitance value is adjustable, regardless of use, it is classified under 8532.30. However, if it is a power capacitor and fixed, it is classified under 8532.10. What documents are required for importing variable capacitors? Usually, a packing list, invoice, contract, product specification sheet, etc. are required, and the declaration elements must be filled in completely. Customs may require samples or technical data to confirm classification. What is the export tax rebate rate for 853230? The export tax rebate rate will be adjusted with policies. It is recommended to check the latest export tax rebate rate library or consult the local customs. Generally, specific values are not provided; official publications shall prevail. How to check the regulatory conditions for 853230? You can check through the official website of the General Administration of Customs or the China Customs Import and Export Tariff. Regulatory conditions may include import prohibition, licenses, etc. Third-party query tools can also be used, but official sources shall prevail.
