Each material supplier:

Some metal minerals have become the main source of revenue for the armed insurgent

groups in the Democratic Republic of Congo, Africa, used to trade arms, continue their

bloody conflict with the government and ravage local civilians, thus causing international

controversy. As a world citizen, we declare and promise not to accept the use of metals

from conflict mines; meanwhile, we also require the suppliers of SHAOXING LINGFENG

MACHINERY FACTORY and SHAOXING ZINING TRADING CO.,LTD. to have the following

requirements:

1. Must fulfill their social and environmental responsibilities;

2. Ensure that the products do not use "conflict minerals" from the DRC and its

surrounding countries and regions;

3. Trace the sources of gold (Au), tantalum (Ta), tin (Sn) and tungsten (W) contained in all

products;

4. Communicate this requirement to your upstream supplier. Conflict metals: refer to minerals from conflict mines in the Democratic Republic of the

Congo, including niobium-tantalite, tinite, tungsten and gold, etc. These minerals are

refined into tantalum (Ta), tin (Sn), tungsten (W) (three T mineral) and gold (Au), which are

used in electronic and other products, respectively.

In the near future, the use of metals produced by certain smelters will be prohibited, so all

key suppliers must trace the origin of the metals used in their parts and the smelters. SHAOXING LINGFENG MACHINERY FACTOR
