We are a company that focuses its activity on the design, manufacture and marketing of chemical products for the leather industry.

Likewise, in our laboratories, we work on the design of leather articles.

All the aspects mentioned are subject to work standards established, contemplated and regulated by the ISO 9001/2015 Standard.

We have a highly qualified technical team, with extensive training and experience in the leather treatment industry.

The study and wide research of processes to which hides are subjected, endows our team with great experience in the treatment of leather to obtain the best leather and split leather.

Our experience and professionalism are our best cover letter, being firmly committed to the search for innovative and more sustainable techniques, to offer our clients the best proposal.

The commitment to continuous improvement of our services and products is one of the main values of our work team.


There are many chemicals used in leather tanning, and every year many new products are introduced on the market, with their parallel risks.

For these reasons, at Química Internacional we adopt a systematic approach to safety in the use of chemical products at work, providing an adequate flow of information with the client about their dangers and the safety measures that must be adopted during their use.


The team of Química Internacional seeks customer identification and satisfaction, basing its quality policy on supplying them with products and services that meet their expectations.

The commitment to continuous improvement of our services and products is one of the main values of our work team.

It is for all these reasons that at QIN we have decided to share the objectives of such important entities in our sector as the LEATHER WORKING GROUP and LEATHER NATURALLY in order to support the manufacture of more sustainable leather and the improvement of the environment.


The experience of our team of professionals, as well as our extensive market knowledge, allow us to base our commitment to the client on the search for quality solutions adapted to their context, which allow us to obtain the necessary quality results.
