Impurity seeding in the scrape off layer plasma as well as controlling the contamination of the core plasma by high Z impurities are essential for ITER baseline scenarios. While fluid models are often used to describe impurity transport, short-lived lower ionization stages of high-Z impurities (e.g., W, Ar) may require a kinetic treatment due to their non-Maxwellian velocity distributions. To address these kinetic effects, the EMC3-EIRENE code package has been extended with a trace kinetic ion transport module in guiding center approximation. This module includes grad-B drifts, mirror-force effects and anomalous cross-field diffusion. Benchmarks with the kinetic ion transport code ERO2.0 showed fair agreement, validating the implementation. First simulations of a tungsten source in the ITER divertor region under an attached, medium-density L-mode plasma scenario demonstrate the module's capabilities. These advancements enhance predictions of impurity transport and plasma contamination control, crucial for ITER and future fusion devices.
