Certification

LEAFTEC spare parts are developed based on technical documentation prepared by the brand’s engineers, using original products as a reference.

Production takes place exclusively in audited factories, where each manufacturer is thoroughly evaluated to ensure compliance with LEAFTEC’s strict quality and logistical standards before manufacturing begins.

The production process relies on durable materials designed to withstand harsh working conditions. Given the aggressive environment created by exhaust heat and DEF fluid, material resilience is a crucial factor in significantly extending the lifespan of LEAFTEC components. All these standards are confirmed by compliance with PN-EN ISO 9001:2015 certification.
