As vanadium redox flow battery (VRFB) projects scale, electrolyte supply agreements are increasingly written against published vanadium pentoxide benchmarks rather than negotiated fixed prices. Understanding how those benchmarks are constructed — and how tax bases differ — has become a core commercial skill for developers and suppliers.
The settlement formula: benchmark × K + C
SunSirs (生意社) states that its benchmark price is generated from price big data and a pricing model and can be used either as a settlement price on a specified date or as an average settlement price over a specified period. The pricing formula is:
Settlement price = SunSirs benchmark price × K + C
Here K is an adjustment coefficient that incorporates items such as payment-term costs, while C is a premium or discount covering logistics costs, brand differentials and regional price differences.
What that means in practice
For an electrolyte contract, K typically absorbs the financing cost of credit terms — a supplier granting 60 or 90 days of payment will build that into the coefficient — while C captures freight from the electrolyte plant to site, the value of a qualified brand, and regional supply imbalances. Because both are negotiated, two buyers referencing the same benchmark on the same day can settle at materially different prices.
Tax basis: the hidden comparability trap
SMM notes that its 99% vanadium pentoxide quotation includes a 13% VAT rate and that no tax rebate applies. The agency explicitly warns that tax-inclusive and tax-exclusive quotations must be aligned before comparison, and that a tax-related difference should not be read as a market price movement.
This matters because international electrolyte offtake agreements frequently reference Chinese domestic quotations. A buyer comparing a VAT-inclusive Chinese assessment with an ex-tax international price without adjustment can misjudge the market by more than ten percent.
Choosing the reference period
SunSirs' trailing-year statistics for V2O5 — a low of 96,583.33 yuan/t, a high of 99,866.67 yuan/t, a median of 98,225 yuan/t and an average of 97,961.04 yuan/t — illustrate why contract drafters choose between spot-date pricing and period averaging. A single-date reference exposes both parties to daily noise; a monthly or quarterly average smooths volatility but delays the pass-through of genuine market shifts.
With the benchmark currently sitting in the mid-to-lower part of its annual range, suppliers may favour shorter averaging windows to capture any recovery, while buyers may push for longer windows to lock in present levels.
