What Happened
On June 30, 2026, China introduced a 60-day payment cap for the energy storage sector — a direct regulatory response to the price war that has squeezed margins across the battery and EV supply chain. The new rule, reported by the South China Morning Post, requires buyers in the energy storage and EV battery industries to settle invoices within 60 days. Companies that fail to comply face enforcement action from Chinese authorities.
If your business supplies components, materials, or equipment to China’s energy storage ecosystem — or if you manufacture batteries inside China — this rule changes your receivables timeline. The South China Morning Post first reported the policy shift on June 30.
Why It Matters
China’s energy storage sector has been in a brutal price war for over 18 months. Battery cell prices dropped by roughly 40% between early 2025 and mid-2026, driven by overcapacity and aggressive discounting. In this environment, payment terms stretched. Suppliers reported waiting 90 to 180 days for settlement — sometimes longer. Smaller firms, including foreign component suppliers, carried the working capital burden while large domestic integrators delayed payment.
The 60-day cap is the government’s attempt to restore order. Beijing’s message is clear: competing on price cannot mean competing on who can delay payment the longest. For foreign businesses, this is a double-edged signal. On one hand, shorter payment cycles improve cash flow predictability. On the other, the rule signals that regulators are watching the sector more closely — and more intervention may follow.
The energy storage market matters — and it is closely tied to China’s manufacturing output, which returned to expansion in June 2026 with a PMI reading above 50. China installed 21.5 GW of new energy storage capacity in 2025, accounting for roughly 40% of global additions. The supply chain behind those installations includes foreign manufacturers of battery management systems, thermal management components, power conversion systems, and specialty materials. If you are in that chain, this rule affects you directly.
The Details
The 60-day cap applies specifically to energy storage and EV battery transactions, according to SCMP reporting. The rule is enforced through China’s existing market regulation framework — meaning the State Administration for Market Regulation (SAMR, 国家市场监督管理总局) and local commerce bureaus will monitor compliance. The regulation targets what authorities describe as “disorder” in the battery supply chain, where payment delays had become a competitive tactic rather than a financing decision.
The policy emerged as part of a broader regulatory push. Earlier in 2026, the Ministry of Industry and Information Technology (MIIT) issued guidelines calling for consolidation in the battery sector, warning that over 60% of China’s battery manufacturers were operating below 50% capacity utilization. The payment cap is a companion measure: it raises the cost of undercutting competitors through unsustainable payment practices, which should accelerate the consolidation MIIT wants.
For foreign suppliers, the rule has immediate operational implications. Under previous conditions, invoicing a Chinese energy storage integrator might mean waiting four to six months for payment. Under the new rule, you have a regulatory basis to demand settlement within 60 days. That said, enforcement is the open question. SAMR can impose penalties, but the speed and consistency of enforcement across different provinces and cities remains unproven. Companies in coastal manufacturing hubs like Jiangsu and Guangdong — where energy storage is concentrated — are likely to see faster enforcement than those in inland provinces.
The 60-day cap also intersects with China’s existing payment delay regulations — and with China’s broader procurement reform, which has been tightening payment practices across government and state-owned enterprise supply chains since mid-2026. The 2020 Regulations on Ensuring Payment to Small and Medium-Sized Enterprises already set a maximum 60-day payment term for government and large enterprise procurement from SMEs. The new energy storage rule extends this principle to a specific industrial sector, regardless of company size — a sign that regulators view battery supply chain health as a strategic priority.
What You Should Do
If your business operates in China’s energy storage or EV battery supply chain, take these steps now:
- Review your payment terms. Audit every customer contract involving energy storage or battery components sold to Chinese buyers. Flag any terms exceeding 60 days for renegotiation. Cite the new regulation as the basis.
- Document every transaction. The rule gives you grounds to escalate non-payment. But you need clear records: delivery confirmation, invoice dates, and payment terms in writing. Without documentation, enforcement is unavailable.
- Monitor local enforcement. Track whether provincial commerce bureaus in Jiangsu (32% of China’s battery production), Guangdong (18%), and Fujian (9%) issue implementing notices. These provinces will set the enforcement pace.
- Assess counterparty health. If a Chinese customer resists the 60-day cap, that is a red flag. The rule squeezes companies that rely on delayed payment to fund operations. A customer that cannot comply may be a credit risk.
For companies planning new investment in China’s battery supply chain, the rule adds a regulatory backstop to your receivables. Factor it into your working capital modeling — but do not assume universal compliance. The gap between regulation and enforcement in China is real, and payment disputes will still arise.
The Number to Remember
60 days. That is now the maximum payment window for energy storage and EV battery transactions in China. For an industry where 90-to-180-day terms were common, this cuts the expected receivables cycle by half or more. If your average collection period in China was 120 days, the rule effectively frees up two months of working capital per invoice cycle — a material improvement for cash-flow-sensitive foreign suppliers.
