Pneumatic power engines and motors - Linear acting (cylinders)
Classification scope of linear pneumatic actuators (841231)
CN code 841231 covers pneumatic power engines and motors with linear action, commonly known as pneumatic cylinders. This includes single-acting and double-acting pneumatic cylinders, rodless cylinders, guided cylinders, compact cylinders and other actuators converting compressed air energy into linear motion. Pneumatic cylinders are fundamental components in industrial automation systems, production lines, packaging machinery, robotics and internal transport systems. Classification is based on the pneumatic operating principle and linear output motion. Hydraulic linear actuators are classified under 841221. Pneumatic valves (8481) and air compressors (8414) are excluded.
Import requirements for pneumatic actuators (841231)
Importing pneumatic actuators under subheading 841231 into the EU is governed by the Union Customs Code. The Machinery Regulation (EU) 2023/1230 applies when the actuator is a machine component. PED 2014/68/EU may apply to cylinders above specified pressure thresholds, though standard pneumatic cylinders at up to 10 bar typically do not fall under PED. Pneumatic cylinders must comply with EN ISO 15552, ISO 6432 and ISO 21287 standards. Importers must hold an EORI number. Documentation includes an invoice, transport document and technical specification. Duty rates should be verified in TARIC. Imports from China and Taiwan are significant.
Applications and market for pneumatic actuators (841231)
Linear pneumatic actuators under subheading 841231 are widely used in industrial automation due to their simplicity, reliability and low cost. In assembly lines, pneumatic cylinders perform clamping, positioning, feeding and sorting operations. In packaging machinery, they drive sealing, cutting and forming mechanisms. In collaborative robotics, they serve as gripper components. In food and pharmaceutical industries, stainless steel cylinders meet hygiene requirements. Leading manufacturers include Festo, SMC Corporation, Parker Hannifin, Aventics (Emerson) and Camozzi. Imports from Asia, particularly China (Airtac) and Taiwan, are growing in the EU market. Industry 4.0 automation trends support growing demand.
Linear pneumatic actuators – ISO standards and Machinery Directive
CN code 8412 31 covers linear pneumatic actuators. These actuators are used in industrial automation, construction machinery and specialist vehicles. Import requires compliance with Machinery Directive 2006/42/EC and ISO standards for hydraulic/pneumatic systems. Customs clearance requires CE certificate and manufacturer's technical documentation.
Frequently asked questions
What actuators are classified under subheading 841231?
Subheading 841231 covers pneumatic actuators with linear motion — single and double-acting pneumatic cylinders, rodless, compact and guided cylinders. They convert compressed air energy into linear motion. Used in automation, assembly lines and packaging machinery.
What standards apply to pneumatic cylinders in the EU market?
Pneumatic cylinders should comply with ISO 15552 (profile cylinders), ISO 6432 (round mini cylinders) and ISO 21287 (compact cylinders) for dimensions, ports and parameters. These standards ensure interchangeability between manufacturers. The Machinery Regulation applies when cylinders are part of a machine.
Are pneumatic cylinders subject to the Pressure Equipment Directive PED?
Standard pneumatic cylinders operating at up to 10 bar typically do not fall under PED 2014/68/EU, as they do not exceed the thresholds for their class. Cylinders with higher working pressure or large bore may be subject to PED. The manufacturer should assess compliance with PED thresholds.
Do linear pneumatic actuators CN 8412 31 require CE marking?
Yes, linear pneumatic actuators CN 8412 31 require CE marking under Machinery Directive 2006/42/EC when placed on the EU market as standalone equipment. Spare parts may be exempt from CE marking obligations.
