For comparing lots and discussing specifications and pricing, not a universal RTV supply threshold.
Content conditions are not the complete definition or RTV purchasing minimums. Check source, beneficiation and physical form for applicability. Do not directly apply this table to ore, slag, dust or recycled material.
Product form
Identify ore/concentrate, mineral type and processing. Express tin as Sn, separately from SnO₂.
Assay and lot information
Sn, Pb, As, Hg, Fe; W / WO₃
Pricing discussion
Actual Sn, associated tungsten, impurities, moisture, quantity and shipping inform pricing, without fixed grade or moisture thresholds.
For comparing lots and discussing specifications and pricing, not a universal RTV supply threshold.
WO₃≥65% is a commercial specification example from the supplied source, not a standard grade established by content alone or a fixed RTV minimum. Discuss mineral type, impurities, moisture and price per lot.
Product form
Distinguish wolframite, scheelite or mixed material; state grade as WO₃. Content alone does not establish a standard grade.
Assay and lot information
WO₃, Sn, Mo, As, P, S, Cu, Pb, Bi
Pricing discussion
Discuss pricing from WO₃, mineral type, impurities, moisture, quantity and delivery; no universal discount factor is assumed.
For comparing lots and discussing specifications and pricing, not a universal RTV supply threshold.
Both columns are low-lead AA references. Identify tin grade and lead category together; discuss actual assays and commercial terms separately.
Size, weight and lot reference Reference ingot weight: 25±1.5 kg; same-grade/class lots up to 50 t. Special ingot, bundle or pallet weights are agreed; do not assume 1 t per pallet.
Product form
Sn99.90 AA / Sn99.95 AA are references. Identify grade and lead category; discuss actual available lots separately.
Assay and lot information
Sn, As, Fe, Cu, Pb, Bi, Sb, Cd, Zn, Al, S, Ag, Ni + Co
Pricing discussion
Actual chemistry, Pb category, ingot weight, packing, quantity and delivery location inform pricing and delivery.
Start with the information available; further details can follow. Material form, quantity, location, available photos/assays and contact details.
From lot information to price discussion
Discuss the pricing basis, testing, payment and delivery arrangements for the particular lot.
