Chapter 87 covers "Vehicles other than railway or tramway rolling-stock, and parts and accessories thereof" in the Harmonized System. This chapter includes motor vehicles (such as automobiles, motorcycles, tractors), non-motor vehicles (such as bicycles, horse-drawn carriages), and parts and accessories specially designed or principally designed for these vehicles. It should be noted that this chapter does not include certain specific types of vehicles, such as railway vehicles (Chapter 86), aircraft (Chapter 88), and ships (Chapter 89). For motorcycles, complete vehicles are classified under heading 8711, while dedicated parts are mainly classified under heading 8714. The full text of heading 8714 is "Parts and accessories of vehicles of headings 8711 to 8713", covering: dedicated parts and accessories for various motorcycles (including mopeds) and bicycles (including pedal cycles), such as frames, forks, rims, spokes, hubs, brakes, transmissions, saddles, pedals, cranks, chain wheels, cylinder blocks, cylinder heads, pistons, carburetors, etc. However, it should be noted that this heading does not include general-purpose parts (such as bolts, nuts, springs, etc.), nor does it include parts already named in other headings for internal combustion engines (such as engine parts of heading 8409). HS code 871425 is a six-digit subheading code. The first 2 digits "87" represent Chapter 87 "Vehicles other than railway or tramway rolling-stock, and parts and accessories thereof". Digits 3-4 "14" represent heading 8714 "Parts and accessories of vehicles of headings 8711 to 8713". Digits 5-6 "25" represent subheading 8714.25, whose specific description is "Cylinder blocks and cylinder heads for motorcycles". Therefore, the complete meaning of this code is: cylinder blocks and cylinder heads dedicated to motorcycles. It should be noted that the cylinder block is the main body of the engine, housing the piston and crankshaft; the cylinder head covers the top of the cylinder block, forming the combustion chamber. Both are core components of motorcycle engines, but are only classified under this subheading when dedicated to motorcycles; if used for other vehicles or general-purpose engines, they may be classified under other codes. The core reason this product is classified under 871425 rather than adjacent codes is that it is dedicated to motorcycles. According to General Rules of Interpretation 1 and 6, heading 8714 explicitly covers motorcycle parts, and subheading 8714.25 specifically names "cylinder blocks and cylinder heads". If the cylinder block or cylinder head is a general-purpose internal combustion engine part (such as for automobiles or general machinery), it should be classified under heading 8409 (parts suitable for use solely or principally with the engines of heading 8407 or 8408). However, because its design, structure, or function is only applicable to motorcycle engines, it is classified under 871425.

Product Name: The Chinese and foreign language names of the declared commodity, which should accurately reflect the product attributes, such as "Motorcycle Cylinder Block" or "Motorcycle Cylinder Head". Brand: Fill in the manufacturer or trademark brand, such as "Honda", "Yamaha", etc. If there is no brand, fill in "No Brand". Model: Fill in the specific model or part number, such as "KPH-12345", to distinguish different specifications. Applicable Vehicle Model: Indicate the motorcycle displacement or model to which the part applies, such as "Suitable for 125cc motorcycles". Material: Fill in the main material, such as "aluminum alloy", "cast iron", etc., which affects classification and customs valuation. Purpose: Explain the specific function of the part on the motorcycle, such as "Used for engine cylinder block assembly". Whether General-Purpose: Declare whether the part is dedicated to motorcycles or can be used for other internal combustion engines. Customs declaration example: Product Name: Motorcycle Cylinder Block Brand: Honda Model: KPH-12345 Applicable Vehicle Model: 125cc motorcycle Material: Aluminum alloy Purpose: Used for motorcycle engine cylinder block assembly Whether General-Purpose: Dedicated to motorcycles Specifications: Bore 52mm, Stroke 48mm Remarks: None Failure to indicate "for motorcycles", leading to classification under 8409 (general-purpose engine parts). Incorrect brand and model entry, affecting customs valuation and classification. Material description is not specific, such as only writing "metal", which may raise doubts.

The core determination basis for classification is: 1) whether the commodity is dedicated to motorcycles; 2) whether it is a cylinder block or cylinder head; 3) whether it is excluded from heading 8409, etc. According to the Explanatory Notes to the Harmonized Commodity Description and Coding System, heading 8714 covers motorcycle parts, but it should be noted that if the part can be used for other vehicles or general-purpose engines, it should be classified as a general-purpose part. In addition, if the cylinder block and cylinder head are semi-finished or unfinished, they should also be judged based on their essential characteristics. In actual classification, reference should be made to the design, structure, function, and applicable vehicle model of the part, and technical materials or samples may be provided if necessary. 8409 Parts suitable for use solely or principally with the engines of heading 8407 or 8408: 8409 covers general-purpose internal combustion engine parts, including engine parts for automobiles, motorcycles, etc., but if the part is dedicated to motorcycles, it is preferentially classified under 8714. The core difference lies in dedication: motorcycle-dedicated parts are classified under 8714, general-purpose parts under 8409. 8711 Motorcycles and mopeds with auxiliary pedals: 8711 is for complete motorcycles, while 871425 is for motorcycle-dedicated parts. If a complete motorcycle is imported, it should be classified under 8711; if it is a part, it should be classified under 8714. 871410 Other parts for motorcycles: 871410 is a subheading for motorcycle parts, but 871425 specifically names cylinder blocks and cylinder heads, which is a more specific subheading. According to General Rule of Interpretation 6, a specific description prevails over a general description. 8483 Transmission shafts and cranks, etc.: 8483 covers general-purpose transmission elements, such as crankshafts, camshafts, etc., but cylinder blocks and cylinder heads are not transmission elements, and if dedicated to motorcycles, they should still be classified under 8714. Is the part dedicated to motorcycles? Is it a cylinder block or cylinder head? Can it be classified under a more specific heading such as 8409? Is it imported together with a complete vehicle? Has sufficient technical documentation been provided?

What is the difference in HS codes between motorcycle cylinder blocks and automobile cylinder blocks? Motorcycle cylinder blocks should be classified under 871425, while automobile cylinder blocks are usually classified under 8409 (if they are general-purpose engine parts) or 8708 (if they are automobile-dedicated parts). The key difference lies in dedication: motorcycle-dedicated parts are classified under 8714, automobile-dedicated parts under 8708, and general-purpose engine parts under 8409. How to determine whether a cylinder block is dedicated to motorcycles? It can be determined by the following aspects: 1) whether the design dimensions and mounting interfaces are only applicable to motorcycle engines; 2) whether it is used in conjunction with a complete motorcycle; 3) whether the technical documentation or brand points to motorcycles. If it cannot be determined, it is recommended to apply to customs for advance classification. When importing cylinder heads, how should the "Applicable Vehicle Model" be filled in the declaration elements? Fill in the specific displacement or model, such as "Suitable for 125cc motorcycles" or "Suitable for Honda CG125". If it is a general-purpose type, indicate "General-purpose" and explain the possible applicable vehicle model range. Can cylinder blocks and cylinder heads be declared together? If both are imported simultaneously as a set of parts and both are dedicated to motorcycles, they can be declared together as "Motorcycle Cylinder Blocks and Cylinder Heads", but this must be clearly stated in the product name. If imported separately, they should be declared separately. If a cylinder block can be used for both motorcycles and other equipment, how should it be classified? If the cylinder block is general-purpose, i.e., not dedicated to motorcycles, it should not be classified under 871425, but should be classified according to its main use under 8409 (engine parts) or other corresponding headings. Classification should follow General Rules 1 and 6. When declaring, does the material of the cylinder block affect the HS code? The material itself does not directly determine the HS code, but it may affect the subheading division. For example, aluminum alloy and cast iron cylinder blocks are both classified under 871425, but the material is one of the declaration elements and must be truthfully filled in for customs review. How to check the tariff rate for 871425? Through the official website of the General Administration of Customs of China, the International Trade Single Window, or professional tariff query tools, enter HS code 871425 to view the MFN rate, general rate, VAT rate, and regulatory conditions. Note that rates may change, and the latest announcement shall prevail. When exporting motorcycle cylinder blocks to the EU, is the HS code the same? The first six digits of the EU HS code are consistent with the international code, both being 871425, but the latter digits may differ due to EU internal subdivisions. When exporting, it is necessary to confirm the EU TARIC code and pay attention to EU anti-dumping or quota measures.
