Commodity Benchmark Normalization

Site Explanation: Commodity Benchmark Normalization A commodity name alone does not identify a price. Lithium carbonate, lithium hydroxide, and spodumene are different products. Cobalt metal and cobalt hydroxide are different. Refined nickel, nickel sulfate, matte, and mixed hydroxide precipitate reflect different processing stages and commercial markets. Every benchmark should identify product, grade, purity, physical form, moisture, geography, delivery point, Incoterm, currency, unit, tax and

Interpretation rule: Results are derived estimates. They are not reported facts unless the inputs themselves come from directly reported, scope-matched evidence.

Currency Conversion to USD

price/fx
Derived result
—

Confirm the exchange-rate quote convention.

USD per Pound to USD per Metric Ton

price*2204.6226
Derived result
—

Preserves mass only; grade and delivery basis must still match.

Dry-Basis Price

wet/(1-moisture/100)
Derived result
—

Moisture must be below 100%.

Contained-Element Price

price/(fraction/100)
Derived result
—

Excludes recovery, conversion, and processing costs.

Payable Content

weight*(grade/100)*(payability/100)
Derived result
—

Use the precise grade and contract payability.

Delivered Price

origin+inland+port+ocean+insurance+duty+customs+dest
Derived result
—

Retain the original Incoterm and delivery point.

Assessment Midpoint

(low+high)/2
Derived result
—

The midpoint is not necessarily a transaction price.

Weighted Material Index - 3 Inputs

w1*(p1/b1)*100+w2*(p2/b2)*100+w3*(p3/b3)*100
Derived result
—

Weights should sum to 1.0. This is an analytical input-cost index, not a selling price.
