Outside of Germany, we work with companies that act as distributors for us and are responsible for local sales. You can find an overview of all our distributors under Contact, International. 

If you have questions regarding your order, delivery or invoice, please contact the dealer/distributor in your country where you placed the order. 

If there is no distributor in your country yet, please contact us by e-mail to info@koch-chemie.com. Your e-mail should contain your contact details as well as information about your business. Afterwards the international sales department will contact you.
