For generations siku toy models have been driven around the playroom. And there's a good reason for that: Since then, fathers buy for their children and grandfathers buy for their grandchildren our toy models which are created for little hands, thanks to their stable construction from metal and from plastic components.

Sieper GmbH is a medium-sized company with headquarters in Lüdenscheid, and founded in 1921. The company employs 650 staff worldwide at various locations. Sieper GmbH produces mechanical and remote-controlled toy models in various scales under the siku brand name. Siku toy models are accurately detailed, robust, and provided with a multiplicity of play functions. Development, design, marketing, administration, and production are located at the company headquarters in Lüdenscheid.

In addition, the Sieper group has further production locations in Poland and China, as well as its own marketing subsidiaries in France and Hong Kong. Siku toy models are marketed worldwide. The major export countries include European states such as France, the Benelux countries, and Scandinavia. However, siku is also an established name in the toy market in overseas countries such as China, Japan, Korea, New Zealand, and Mexico.

Fun with SIKU


SIKU toy models meet the highest quality and safety requirements and give plenty of hours of enjoyment and safe play in the kids’ playroom. To ensure these requirements are met, SIKU toy models are manufactured from die-cast metal and plastic parts. This makes them sturdy and hard-wearing, making realistic play possible of everyday scenes in road traffic, on the building site, with emergency rescue services or in agriculture. SIKU toy models contain no and PVC and meet German and international standards and guidelines for the safety of toys. SIKU toy models comply with the European Spielzeugrichtlinie 2009/48/EG, which is based on the CE code and other standardized norms (toy safety in accordance with EN 71 und EN 62115).  In addition to our compliance with high quality standards for all materials and the manufacture of our products, we are also committed to the protection of all employees working for us.

That’s why we have defined ecological and social behaviour guidelines that guarantee safety at the workplace and protection from health hazards.  To make our contribution to global solutions, our company became a member of the ICTI CARE Process. The ICTI CARE Process is an initiative of the International Council of Toy Industries (ICTI) for the toy industry’s ethical manufacturing programme, aimed at ensuring safe and humane workplace environments. The behavioural guidelines of Sieper GmbH apply to all suppliers, while the ICTI programme is aimed at toy industry suppliers.

Sieper GmbH also has ISO 9001:2015 certification for the continual improvement and as a basis for the development of our organizational structures and procedures.
