Copper scrap on CIF terms needed

Our company is looking for copper scrap.

The following are our needs:
1. Product Type:
Copper Scrap (99.7%): 15,000 tons per month.
Copper Cathode (99.97%): 10,000 tons per month.
2. Arrived at the destination: China.
3. Production restrictions: Safe countries other than China, the United States, and Vietnam.
4. Terms of Trade: CIF.
5. Payment Method: Irrevocable Letter of Credit (L\C).
Because we have a large number of purchases, we use L/C transactions to reduce the risk of transactions.
We are the ultimate buyer (not the agent). We directly open the L/C to the seller!
We hope that the monthly supply of suppliers will reach 3,000-5,000 tons/month
If your company has more than one product, please tell me the unit price and monthly supply quantity (supply time is more than six)
