Trade Regulations

Compliance with Laws and Trade Regulations

When you buy from Sigma Supply, you can rest assured knowing that all regulations and laws are followed and that your products are sourced from equitable partners.  We ensure this by having our vendors demonstrate adherence to all applicable trade and import/export laws and regulations that apply to their activities (including those issued by the United Nations, the European Union, the U.S. government and individual countries where the vendors will be importing or exporting goods or materials).  Vendors must not participate in any international boycotts that are prohibited by the U.S. government.  Additionally, vendors must adhere to all trade sanctions imposed by the U.S. Government, including, but not limited to, sanctions imposed on countries, entities and individuals.  It is further expected that our vendors do not engage in any practices that impose on the civil liberties of the human workers, with respect to local laws.     


Sourcing Materials

Sigma Supply’s material sourcing serves to further demonstrate our commitment to monitor the full chain of custody, from raw materials to the finished product.  Our suppliers are required to maintain documentation showing the origin and place of production of incoming materials and that such materials were obtained consistent with applicable environmental laws.  Suppliers shall exercise due diligence.  This may include compliance with the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas.  This covers the entire supply chain with respect to the sourcing of all gold, columbite-tantalite (coltan), cassiterite, wolframite, and their derivatives (including tin, tantalum, and tungsten) contained in their products.  We purposely avoid any metals from the Democratic Republic of the Congo (“DRC”) or any adjoining country.  The supplier must ensure that these metals did not benefit any armed groups who perpetrate human rights abuses in the DRC, or an adjoining country.
