Chapter 84 covers nuclear reactors, boilers, machinery, mechanical appliances and their parts, and is one of the most technologically advanced chapters in the HS classification. This chapter includes power machinery, pumps, fans, valves, bearings, transmissions and other general machinery, as well as specialized machinery for agriculture, textiles, printing, food processing, etc. Valves, as key components for fluid control, are classified mainly based on their working principle, structural characteristics and use, rather than material or size. Heading 8481 specifically covers valves, cocks, taps and similar appliances for pipes, boilers, tanks, vats or the like, including pressure-reducing valves, check valves, safety valves, relief valves, gate valves, ball valves, butterfly valves, globe valves, etc. This heading includes not only manual valves but also automatically controlled valves, but attention must be paid to distinguishing them from mechanical parts such as bearings of 8482 and transmission shafts of 8483. The first 2 digits 84 represent Chapter 84, machinery and mechanical appliances; digits 3-4, 81, represent heading 8481, i.e. valves and similar appliances; digits 5-6, 80, represent subheading 848180, i.e. 'other valves', covering valve types not listed in 848110 to 848170. 848110 is pressure-reducing valves, 848120 is valves for oleohydraulic or pneumatic transmissions, 848130 is check valves, 848140 is safety or relief valves, 848150 is other valves (such as gate valves, ball valves, etc.), and 848180 includes valves not specifically named, such as butterfly valves, diaphragm valves, cocks, etc. The goods are classified under 848180 because they are valve-type appliances but do not meet the description of any specific subheading from 848110 to 848170. For example, if they were pressure-reducing valves they should be classified under 848110, if they were valves for oleohydraulic transmission under 848120, and if they were check valves under 848130. Only valves that cannot be classified under the above subheadings, such as butterfly valves, diaphragm valves, cocks, etc., are classified under 848180.

Common Mistakes：
Mistakenly classifying pressure-reducing valves under 848180, when they should actually be under 848110.
Mistakenly classifying valves for oleohydraulic transmission under 848180, when they should actually be under 848120.

🎯 Classification Logic
The core basis for classification is the valve's structure, function and working principle. First determine whether it is a valve-type appliance, then determine the subheading according to the specific type. If it is a pressure-reducing valve, valve for oleohydraulic transmission, check valve, safety valve, etc., it should first be classified under the corresponding subheading; if none apply, it is classified under 848180. At the same time, attention must be paid to distinguishing it from parts such as bearings of 8482 and transmission shafts of 8483; valves generally have a fluid control function. 848110 Pressure-reducing valves: Pressure-reducing valves are used to regulate fluid pressure and keep outlet pressure stable, while 848180 covers other valves not elsewhere specified. 848120 Valves for oleohydraulic or pneumatic transmissions: Valves for oleohydraulic or pneumatic transmissions are used in hydraulic or pneumatic systems to control fluid direction, pressure or flow, and are different from the general valves of 848180. 848130 Check valves: Check valves only allow fluid to flow in one direction and prevent backflow, while 848180 includes other types of valves. 848140 Safety or relief valves: Safety or relief valves are used for overpressure protection and open automatically when pressure exceeds a set value, which differs from the conventional valve function of 848180. Is the specific type of valve clearly identified? Have subheadings 848110 to 848170 been checked? Has it been confirmed that the valve is not a pressure-reducing, transmission, check or safety valve? Have the valve's use and working principle been verified? Has it been distinguished from adjacent codes 8482 and 8483?
