  Recent observations have shown that circumbinary discs can be misaligned with
respect to the binary orbital plane.The lack of spherical symmetry, together
with the non-planar geometry of these systems, causes differential precession
which might induce the propagation of warps. While gas dynamics in such
environments is well understood, little is known about dusty discs. In this
work, we analytically study the problem of dust traps formation in misaligned
circumbinary discs. We find that pile-ups may be induced not by pressure
maxima, as the usual dust traps, but by a difference in precession rates
between the gas and dust. Indeed, this difference makes the radial drift
inefficient in two locations, leading to the formation of two dust rings whose
position depends on the system parameters. This phenomenon is likely to occur
to marginally coupled dust particles $(\text{St}\gtrsim1)$ as both the effect
of gravitational and drag force are considerable. We then perform a suite of
three-dimensional SPH numerical simulations to compare the results with our
theoretical predictions. We explore the parameter space, varying stellar mass
ratio, disc thickness, radial extension, and we find a general agreement with
the analytical expectations. Such dust pile-up prevents radial drift, fosters
dust growth and may thus promote the planet formation in circumbinary discs.
