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, ranging from household appliances to semiconductor devices, but explicitly excludes goods excluded by the notes to Section XVI. The core issue is whether the goods have an electrical or electronic function and are not more specifically classified under other chapters. Heading 8542 covers integrated circuits (ICs) and parts thereof. Integrated circuits refer to circuits formed by semiconductor processes or thick-film or thin-film processes, in which circuit elements (transistors, diodes, resistors, capacitors, etc.) are inseparably combined on a single substrate, or combined on an insulating substrate to form a circuit module with a specific function. This heading includes monolithic integrated circuits, hybrid integrated circuits, multi-chip integrated circuits, and memories, etc., but does not include circuit boards merely assembled from discrete components. First 2 digits 85: belongs to Chapter 85, representing electrical machinery and equipment and parts thereof. Digits 3-4, 42: represents heading 8542, i.e., integrated circuits. Digits 5-6, 90: represents subheading 854290, i.e., parts of integrated circuits. Therefore, 854290 specifically refers to parts used for integrated circuits (8542), which are not themselves complete integrated circuits but are constituent parts thereof, such as diced semiconductor wafers, chip carriers, lead frames, packaging housings, etc. Note: if the part itself is a complete integrated circuit, it is classified under other subheadings of 8542, not 854290. This commodity is classified under 854290 because it is a dedicated part of an integrated circuit, not a complete integrated circuit. If it were a complete integrated circuit, it should be classified under subheadings 854231 to 854239, etc.; if it were a discrete device, it would be classified under 8541; if it were a printed circuit assembly, it might be classified under 8548 or according to the complete machine. 854290 specifically covers parts of integrated circuits not named in other subheadings, reflecting the principle of distinguishing parts from complete articles.

🎯 Classification Logic
Core classification determination basis: First confirm whether the commodity is a dedicated part of an integrated circuit, i.e., whether it is dedicated for use with integrated circuits under 8542 and is not itself a complete integrated circuit. Second, check whether there is a more specific listing under other headings, such as discrete devices under 8541, printed circuits under 8534, etc. Finally, according to the General Rules for the Interpretation of the Harmonized System, if it cannot be distinguished, classify according to the essential character. For parts, two conditions must be met: "dedication" and "not a complete article." 854231 Processors and controllers: 854231 is a complete integrated circuit with processing functions; 854290 is a part thereof and does not have complete functions. 854232 Memories: 854232 is a complete memory integrated circuit; 854290 is a part of a memory, such as gold fingers on a memory module, housing, etc. 854110 Diodes: 854110 is a discrete device diode; 854290 is a part of an integrated circuit, usually an integration of multiple elements. 853400 Printed circuits: 853400 is a bare printed circuit board; 854290 is a part of an integrated circuit, which may be included on a printed circuit but is not itself a circuit board. 854890 Other electrical parts: 854890 is electrical parts not named under other headings; 854290 specifically refers to integrated circuit parts and is more targeted. Is the part dedicated for use with 8542 integrated circuits? Is the part a complete integrated circuit? Is there a more specific listing under other headings? Do the material and function support classification under 854290? Is it diced or encapsulated?

❓ FAQ
How can one determine whether a part is an integrated circuit part or another electrical part? The key is dedication: if the part is dedicated for use with integrated circuits (such as lead frames, packaging housings, wafers) and is not itself a complete integrated circuit, it is classified under 854290. If it is general-purpose or used for other electrical equipment, it may be classified under 854890 or other headings. Should diced semiconductor wafers be classified under 854290? Yes, diced but unencapsulated semiconductor wafers, if dedicated for use with integrated circuits, are generally classified under 854290. However, if a complete circuit has been formed and it has functions, it may be classified under 854231, etc. Undiced wafers are generally classified under 3818 or 854290, depending on the specific state. How are integrated circuit packaging housings classified? If a packaging housing is dedicated for use with integrated circuits and is made of plastic, ceramic, etc., it is generally classified under 854290. However, if the housing itself carries circuits or connectors, it may be classified under other headings. Proof of dedication is required. How can the import tariff rate for 854290 be checked? Tariff rates change; it is recommended to consult the "Import and Export Tariff of the People's Republic of China" issued by the General Administration of Customs of China or check through the "Customs Classification Pre-ruling" system. You may also use the tariff inquiry tool on the official website of the General Administration of Customs, entering the code and country of origin to obtain the latest tariff rate. If an integrated circuit part is a kit composed of multiple parts, how is it classified? If the kit already has the character of a complete integrated circuit, it should be classified as a complete integrated circuit; if it is merely a kit of parts and is not assembled, it is generally classified as parts, but it is necessary to determine whether it constitutes essential character according to General Rule 3(b). It is recommended to provide a detailed list and use. What is the main difference between 854290 and 854890? 854290 specifically refers to parts of integrated circuits, while 854890 is electrical parts not named under other headings. If a part is dedicated for use with integrated circuits, priority is given to classification under 854290; if dedication cannot be proven, it is classified under 854890. How should cross-border e-commerce sales of integrated circuit parts be declared? It is necessary to truthfully declare elements such as product name, use, material, brand, and model, and ensure accurate classification. For small parcels, declaration may be simplified, but detailed information should be retained for inspection. It is recommended to use classification opinions recognized by customs. Are there export controls on integrated circuit parts? Some high-performance integrated circuits and their parts may be subject to export controls and require licenses. For details, consult the "Catalogue of Dual-Use Items and Technologies Subject to Import and Export License Administration." Enterprises should pay attention to the latest regulations to avoid violations.
