September Tax Break
China's 2% consumption tax on lithium-ion batteries takes effect September 1, and it creates a measurement problem before it creates a margin problem. The tax is booked under "taxes and surcharges" in Chinese financial statements, below gross profit (BigGo Finance, July 20). It does not appear as an invoice line item. SMM and InfoLink transaction-price assessments may therefore register no movement while producer netback falls by ~RMB 0.007/Wh.
That figure sits within the existing SMM–InfoLink spread on 314 Ah LFP cells (roughly RMB 0.006/Wh). A September quote that looks flat against August could be absorbing the full tax. Neither assessor has announced a methodology update to distinguish tax-inclusive from tax-exclusive observations. From September, this section will track invoice-price and tax-normalized trajectories separately. Until assessors tag their observations by tax basis, the second derivative on the headline series is unreadable.
Who Finances the Floor
Published ¥/Wh cost decompositions track lithium carbonate, cathode processing, separator, electrolyte, electricity, labor, and depreciation, but not the eight to ten months of working capital that upstream suppliers extend to cell makers through payables and commercial acceptance bills. CATL's combined trade and notes payable reached RMB 355.5B at H1 2026, roughly $49B of supplier balance sheet financing the system's largest producer. For Tier-3 producers at 30–40% utilization, the same credit architecture is survival infrastructure. The regulatory mechanisms meant to compress it accommodate current practice through at least mid-2027.

Measuring Tier-2 Chinese Cell Producers Against CATL's H1 2026 Numbers
CATL's H1 2026 filing — the only complete interim report from a major Chinese cell producer as of today — defines what leader economics look like at the current LFP cell floor: 94.86% utilization, ~21% blended battery gross margin, RMB 60.2B in operating cash flow. Measured against that baseline, the three Tier-2 producers with partial data available occupy distinct positions. Roughly 90% of Gotion's forecast H1 net profit came from securities holdings rather than battery operations, Farasis consumed RMB 1B in monetary funds in a single quarter, and REPT's reported turnaround cannot yet be verified against a full filing. Four indicators from these disclosures tell a procurement team which suppliers can hold pricing for the life of a contract.
