Subheading 8413 50 of the Combined Nomenclature covers other reciprocating positive displacement pumps not classified under the preceding subheadings of heading 8413. This includes high-pressure plunger pumps, mechanically or pneumatically driven diaphragm (membrane) pumps, industrial piston pumps, hydraulic piston pumps and metering pumps for chemical processes. Reciprocating positive displacement pumps operate by cyclically displacing a defined volume of liquid through piston or diaphragm movement. Classification under 8413 50 requires distinguishing from rotary positive displacement pumps (8413 60), centrifugal pumps (8413 70), concrete pumps (8413 40) and engine pumps (8413 30). Classification follows GRI Rules 1 and 6, with the key criterion being the reciprocating principle of operation. Where classification doubts arise, a BTI ruling is recommended.

Importing reciprocating positive displacement pumps under subheading 8413 50 into the European Union requires compliance with the Union Customs Code (Regulation (EU) No 952/2013). The importer must hold an EORI number and file an electronic customs declaration. Reciprocating pumps are subject to the Machinery Regulation (EU) 2023/1230, requiring an EU declaration of conformity and CE marking. High-pressure pumps may be subject to the Pressure Equipment Directive (PED) 2014/68/EU, establishing requirements for pressure equipment based on risk category. Pumps for hazardous substances must comply with REACH regarding construction materials. Pumps for explosive atmospheres require ATEX certification under Directive 2014/34/EU. Import documents include the commercial invoice, transport document, CE declaration, PED certificate (where applicable) and technical specification with operating pressure and capacity data. MFN duty rates should be verified in TARIC.

MFN duty rates for reciprocating pumps under subheading 8413 50 should be verified in the TARIC database. Preferential rates may be available under EU FTAs including CETA, EPA, EU-South Korea and TCA. Reciprocating pumps are key industrial equipment components and may benefit from autonomous tariff suspensions if included in the relevant Council Regulation. Imports from Russia and Belarus are subject to sanctions restrictions. Importers should check TARIC for anti-dumping or countervailing duties from specific countries. Import VAT is charged at the national rate. Specialised pumps for energy, mining and chemical industry applications may be subject to particular end-use controls. All current rates and trade measures should be verified in TARIC before filing the customs declaration.

CN code 8413 50 covers reciprocating pumps. Import into the EU is subject to TARIC duty rates and requires compliance with Machinery Directive 2006/42/EC. Pumps operating under pressure also fall under the Pressure Equipment Directive PED 2014/68/EU. Centrifugal pumps must meet ecodesign energy efficiency requirements. Customs clearance needs CE certificate and technical documentation.
