Ultrafine copper powder required, 8 tons monthly to UAE

I am interested in buying ultrafine copper powder with a chemical purity of 99.9999%.
Volume: 8 tons per month.
Please send your offers with the following information:
- specifications (particle size) ;
- whether there are certifications available (e.g., ISO or other standards);
- delivery terms.
- payment terms (preferred payment methods and conditions);
- price (pricing per ton for monthly deliveries up to 8 tons).
Once I receive the above information, I will be able to confirm the volume and proceed with further discussions.
