Rough Antimony Oxide Powder
Antimony Oxide Powder
1. Quality Standard
Sb≥70%Pb/Sb≤0.23%As/Sb≤0.8% Moisture≤2% .
2. The Grade Determination & Price Markdown Standard
2.1 Considered Sb≥80% as benchmark price.
2.2 80%>Sb≥75% thus decrease USD 35 /MMt compared with benchmark price.
2.3 75%>Sb≥70% if 1% below, thus decrease USD 100 /MMt compared with 2.2 item.
3. Price Markdown & Rejection Stipulation for Impurity over Standard
3.1 Pb/Sb, if 0.01% exceeds, thus decrease USD 20 /MMT.
3.2 As/Sb, if 0.1% exceeds, thus decrease USD 20 /MMT..
3.3 Pb/Sb>1%or As/Sb>3%,rejection.
4. Price Markdown Stipulation for Moisture over Standard
If moisture exceeds 0.1%, thus the prices decrease USD 2 /MMT.
Raw Materials for Antimony White (Sb2O3)
1. Quality Standard
Sb≥99.65%Pb≤0.1%As≤0.05%Cu≤0.01%.
Fe≤0.02%S≤0.04%Se≤0.005%Sn≤0.003%Bi≤0.003%.
2. The Stipulation of Price Markup & Price Markdown
If the raw materials quality of antimony white comes to #1 antimony standard (99.85% Antimony Metal), the price will be increased USD 20/MMT on the benchmark price of antimony white raw materials.
If the quality comes to 0# antimony standard (99.9% Antimony Metal), the price will be increased USD 35/MMT on the benchmark price of antimony white raw materials.
If the quality can not come to the standard of antimony white raw materials, and only the single element exceeds standard, i.e., Pb exceeds standard but within 0.20%, or As exceeds standard but within 0.06%, or Cu, Fe, S and Se exceed standard but within 0.5 times, the price will be decreased USD 20/MMT on the benchmark price of antimony white raw materials.
If Pb exceeds standard but within 0.24%, or As exceeds standard but within 0.07%, or Cu, Fe, S and Se exceed standard but within one times, the price will be increased USD 35/MMT on the benchmark price of antimony white raw materials; if the impurities exceed the above specifications, the price can be negotiated separately.
3.If Cu≥0.10%or Bi≥0.03%, rejection.
