Chapter 85 covers electrical machinery and equipment and parts thereof; sound recorders and reproducers, television image and sound recorders and reproducers, and parts and accessories of such articles. This chapter has an extremely broad scope, including everything from household appliances to precision electronic components, but excludes certain specific goods such as insulated wire (heading 85.44) and semiconductor devices themselves (heading 85.41). Heading 8541 includes: diodes, transistors and similar semiconductor devices; photosensitive semiconductor devices; light-emitting diodes (LEDs); mounted piezoelectric crystals; and parts of the foregoing articles. Note, however, that parts of 8541 do not include articles classified solely by material (such as plastic shells or glass encapsulation), nor do they include complete integrated circuits (classified under 8542). Code 854190 is a six-digit subheading. The first 2 digits 85 = Chapter 85 (electrical machinery and equipment); digits 3-4, 41 = heading 8541 (semiconductor devices; light-emitting diodes; mounted piezoelectric crystals); digits 5-6, 90 = subheading 8541.90, meaning "parts". Therefore 854190 specifically refers to parts dedicated to semiconductor devices, LEDs, piezoelectric crystals, etc. under heading 8541, rather than the complete devices themselves. The goods are parts of semiconductor devices, not complete devices. If they were complete diodes, transistors, or LEDs, they should be classified under other subheadings of 8541 (such as 8541.10 or 8541.40). If the parts are general-purpose electronic components (such as resistors or capacitors), they should be classified under 8542 or other headings. 854190 is specifically for parts dedicated to the goods listed in 8541, such as chip carriers, lead frames, and packaging housings.

Product Name: The specific name of the declared goods, which should accurately reflect the use of the part, such as "lead frame for semiconductor devices". Use: Explain for which semiconductor device the part is used (such as diodes, transistors, LEDs) and its end-use application. Material: Main material composition, such as copper alloy, plastic, ceramics, silicon, etc., which affects classification. Brand: Manufacturer or brand name; if there is no brand, fill in "no brand". Model: Specific model or specification to facilitate identification of the part's dedicated nature. Whether Dedicated Part: Declare whether the part is dedicated to devices under heading 8541 or is a general-purpose part. Processing Method: Such as stamping, injection molding, cutting, etc., which affects the classification determination. Product Name: Lead frame for semiconductor devices; Use: Used in the manufacture of transistors, ultimately for mobile phone chargers; Material: Copper alloy; Brand: ABC; Model: LF-123; Whether Dedicated Part: Yes; Processing Method: Stamped and formed. Misclassifying complete semiconductor devices under 854190, when they should actually be classified under other subheadings of 8541. Misclassifying general-purpose electronic parts (such as resistors) under 854190, when they should be classified under 8542 or other headings. Ignoring the material, which may lead to classification under a heading classified by material (such as copper articles under Chapter 74).

Core basis for classification: 1) whether the goods are dedicated parts of semiconductor devices, LEDs, or piezoelectric crystals under heading 8541; 2) whether they already possess the characteristics of dedicated parts rather than general-purpose parts; 3) whether they are excluded from other headings of Chapter 85 or headings classified by material. Refer to the Explanatory Notes to the Import and Export Tariff of the People's Republic of China on 8541.90. 854110 Diodes: 854110 is complete diodes, while 854190 is parts of diodes. If the goods already have the complete function of a diode, they should be classified under 854110. 854140 Photosensitive semiconductor devices, LEDs: 854140 is complete photosensitive devices or LEDs, and 854190 is their parts. If the goods are LED chips but not encapsulated, whether they are classified under 854140 or 854190 requires specific determination. 854231 Processors and controllers: 854231 is integrated circuits, and 854190 is parts of discrete devices. Parts of integrated circuits are generally classified under 854290, not 854190. 853400 Printed circuit boards: 853400 is printed circuit boards, which belong to electronic components, while 854190 is parts of semiconductor devices. If the part is a PCB, it should be classified under 853400. Are the goods dedicated parts of devices under heading 8541? Do the goods already have the complete function of a device? Are the goods general-purpose electronic components? Would it be more appropriate to classify the goods by material? Are the goods parts of integrated circuits under heading 8542?

What exactly are the "parts of semiconductor devices" under HS code 854190? They include parts dedicated to diodes, transistors, LEDs, piezoelectric crystals, etc. under heading 8541, such as lead frames, packaging housings, chip carriers, bonding wire, etc. However, they do not include general-purpose electronic components (such as resistors and capacitors) or complete devices. How can one determine whether a part is a dedicated part or a general-purpose part? Dedicated parts refer to parts used solely or principally with devices under heading 8541 and that cannot be used with goods of other headings. General-purpose parts such as standard screws or general plastic shells should be classified under other headings according to material or use. Should the plastic housing of a semiconductor device be classified under 854190? If the housing is dedicated to devices under heading 8541 and does not constitute a complete device, it may be classified under 854190. However, if it is a general-purpose plastic shell, it should be classified under Chapter 39 as plastic. The determination should be based on its dedicated nature. What is the difference between 854190 and 854290? 854190 is parts of semiconductor devices, LEDs, and piezoelectric crystals under heading 8541; 854290 is parts of integrated circuits under heading 8542. The dedicated objects of the two types of parts are different and must not be confused. What are common errors in declaration elements when importing parts of semiconductor devices? Common errors include: generic product names, failure to link the use to devices under 8541, omission of material, and misreporting of dedicated nature. Product name, use, material, brand, model, and whether it is a dedicated part should be filled in in detail. Where can one inquire about the tariff rate and regulatory conditions for 854190? One may consult the Customs Import and Export Tariff of the People's Republic of China, the website of the General Administration of Customs, or use the "Customs Classification Pre-ruling" service. Tariff rates change, so the latest tariff should prevail. If a part can be used both for devices under 8541 and for integrated circuits under 8542, how should it be classified? If the part is a general-purpose item, it should be classified according to its principal use or material. If the principal use cannot be determined, reference may be made to General Interpretative Rule 3(c) for classification from the last in numerical order, or a pre-ruling may be applied for. What is the export tax rebate rate for goods under 854190? Export tax rebate rates are adjusted according to national policies, and the latest export tax rebate rate database should be consulted. Generally, the rebate rate for parts of semiconductor devices is relatively high, but the specific rate should be based on what is issued by the tax authorities.
