Automatic door closers

CN code 830260 covers automatic door closers of base metal, which are mechanical or hydraulic devices that ensure a door leaf closes automatically and in a controlled manner after it has been opened. The category includes overhead hydraulic door closers in both regular-arm and slide-channel configurations, overhead concealed door closers recessed into the door leaf or the transom frame, floor-spring door closers mounted in the floor beneath the pivot axis of the door, and electromagnetic or electropneumatic hold-open devices for fire and escape doors. The operating principle of a hydraulic door closer combines a return spring that drives the closing stroke with an oil-filled damping circuit that controls closing speed; separate valves typically allow independent adjustment of closing speed, latching speed and back-check resistance. CN 830260 is an important subheading for fire protection compliance: doors on fire compartment boundaries require certified automatic closing devices to prevent the spread of fire and smoke, and the presence of a compliant door closer is a mandatory condition for the fire door assembly to maintain its rated fire resistance. This code is also relevant for controlled-access doors, entrance systems and public building doors where unassisted closing is mandated by building regulations or accessibility standards.

The range of products covered by CN 830260 spans several technically distinct categories, each suited to different architectural and regulatory requirements. Overhead door closers with a standard or parallel arm are the most widely installed type, used on interior and exterior doors in offices, schools, hospitals, retail premises and residential buildings. The closing force is defined by the EN size class, ranging from EN 2 for lightweight internal doors up to EN 6 for heavy-duty exterior doors. Slide-channel cam-action closers allow the arm to remain parallel to the door throughout the opening arc, reducing projection into the opening and improving compliance with accessibility standards for people with disabilities. Concealed overhead closers and transom-integrated closers are recessed into the door or frame and are preferred in architectural and heritage applications where a clean visual appearance is paramount. Floor closers are used under frameless glass doors in glazed entrances and are a standard product in commercial and retail construction projects. Electromagnetic hold-open devices, which release and allow the closer spring to shut the door upon activation of a fire alarm signal, are also classified under 830260 and are mandatory on many fire door assemblies in buildings used by the public.

Classification of automatic door closers under CN 830260 is generally unambiguous, as the subheading is dedicated and clearly defined. The main import compliance challenge lies in product certification requirements rather than tariff classification. Door closers intended for use on fire doors or smoke-control doors must be certified to EN 1154 (controlled door closing devices) and, where the harmonised standard mandates conformity assessment, bear CE marking under the Construction Products Regulation (EU) No 305/2011. The accompanying Declaration of Performance (DoP) must specify the relevant essential characteristics, including size class, suitability for fire and smoke doors and durability category. The DoP must be issued by the manufacturer or importer, and the conformity assessment must be carried out or overseen by an EU-notified body. Door closers for general building use that are not covered by a harmonised standard requiring CE marking do not need to be CE marked, but must comply with the EU General Product Safety Regulation. Importers should verify in the TARIC database whether preferential duty rates apply under an EU free trade agreement with the country of supply and whether any anti-dumping or other trade defence measures are currently in force. Commercial import documentation should include the invoice, packing list, transport document, technical datasheet and applicable test certificates or CE declarations of performance.

CN code 8302 60 covers automatic door closers. Fittings and mountings imported into the EU are subject to TARIC duty rates. Building fittings require compliance with the Construction Products Regulation EU 305/2011 and harmonised EN standards. Furniture and vehicle fittings must meet relevant sector standards. Customs clearance requires commercial invoice and declaration of conformity.
