Copper Cathode from AMK is mined from partial owned Mines in Mexico and Chile and we are shipping our product to China so pickup can be in any North American or Asian ports. Because we own it, we have full confidence in our Product. There is not much real copper out there on the market and this price is very good for something that is actually real and not the misleading offers that are on the internet. We have 19 warehouses in China, 5 in Los Angeles, and various others between Canada and Argentina all along North and South America. This product along with aluminum and other products are mined in Mexico and South America and is shipped to China for processing. Buyers can test, verify and tour the facilities anytime, just let me know what country and when you want to make the site visit and we can set it up. We can also call the mines at any time for a discussion if there are any other questions on the procedures. An SBLC is fine and what most groups we sell to use. You can start out with a small shipment and increase the size once your buyers are satisfied with the quality. Its the best quality on the market today.
