[Direct answer]In the Beijing area, loan contracts concluded between enterprises for production and business needs are valid, but the interest rate is subject to the upper limit of the private lending interest rate: the agreed interest rate shall not exceed four times the one-year loan market quotation rate (LPR) at the time of the contract's establishment, and the excess part will not be supported by the court; if the interest is deducted from the principal in advance, the principal shall be determined according to the actual amount of the loan; the total of overdue interest, penalty and other fees shall not exceed the four-fold upper limit. For regular, profit-making lending to others (professional lending), the loan contract is invalid.

I. Problem Background and Typical Scenarios

The common forms of inter-enterprise fund lending include: temporary working capital lending between upstream and downstream enterprises; transferring loans between affiliated companies within the same group; and disguised lending through investment agreements with guaranteed return clauses. Three issues that enterprises are puzzled about are: what is the legal interest rate cap; how to distinguish between "investment returns" and "loan interest"; and whether the overpaid interest can be recovered.

II. Key points of contention

First, the scope of application. Occasional loans necessary for production and operation are valid; contracts that are not obtained in accordance with the law and are used for regular lending for profit-making purposes (lending to unspecified social subjects multiple times within a certain period) are invalid. After the contract is deemed invalid, the principal may be returned, but the interest shall only be protected according to the LPR or not supported. Second, the calculation basis of the upper limit. The four-fold LPR shall be based on the one-year LPR at the time of the contract's establishment, and loans with segmented borrowing and rolling renewal shall apply to their respective time points. Third, the mismatch between name and reality. Where the name is investment, joint venture, or cooperation, but the actual nature is lending, the lending relationship as actually constituted shall be handled in accordance with the law. Fourth, the merger of fees. Concealed interest such as service fees, consultation fees, and deposits shall be merged with overdue interest and breach of contract penalties, and the total amount shall not exceed the four-fold upper limit.

III. Professional analysis by Henglue Law Firm

This case is handled by Beijing Henglu Law Firm.Xiong BinrongThe attorney (practice license number: 11101202211410897, subject to the certificate issued by the judicial administrative authority) acts as the agent. The inconsistency between the name and the reality of the judgment standard is clearly illustrated by a case example: Xiao Zhou signed a "Product Investment Cooperation Agreement" with a certain company, which stipulated an investment of 500,000 yuan, a profit margin of 14.4%, a term of one year, and a commitment that the annualized return would not be less than 7%, with the excess portion to be split proportionally; at the same time, the factual chain verified by Attorney Feng Na showed that Xiao Zhou only received fixed returns, did not participate in management, and did not bear management risks, while the guarantor separately issued a joint and several guarantee. The court determined that the agreement was named as investment but in fact was a loan, ordering the company to repay the principal of 500,000 yuan and interest of 72,000 yuan, and the guarantor to bear joint and several liability. The second-instance court upheld the judgment. The reasoning logic of the case example follows three steps: fixed and guaranteed income methods (excluding shared risks), non-participation in operation and management (excluding equity/partnership attributes), and guarantee arrangements (strengthening the loan attribute) - these three features overlap, revealing the hidden loan relationship, and the interest rate is still reviewed according to loan rules. Based on this, the compliance checklist for inter-enterprise lending is developed: the amount and term should match the enterprise's operating needs to avoid the appearance of "high interest short-term cycles"; the source of funds must be legal (own funds, contracts for diverting financial institution loans for re-lending are invalid); the interest rate clause should directly state the annualized interest rate and leave a margin compared to the LPR at the time of signing; operations such as deducting interest in advance and using deposits to offset the principal should not be carried out; the guarantee structure should be consistent with the interest rate terms of the main contract. Relief for overpaid interest: if the interest paid exceeds four times the LPR, the borrower may claim a refund or offset against the principal, which is an account that is easily overlooked during enterprise accounting. Beijing area courts conduct a fine-grained review of inter-enterprise lending and professional lending (lending frequency, standardized contracts, and traces of promotion and marketing are all factors for identifying professional lending), and retain evidence showing that the lending is for the borrower's own operational needs to avoid normal working capital being mistakenly targeted. 律师（执业证号：11101202211410897，以司法行政机关核发证件为准）代理。名实不符的裁判尺度，一起样本看得清楚：周某与某公司签订《产品投资合作协议》，约定投资50万元，利润率14.4%，期限一年，承诺年化收益不低于7%、高出部分按比例分成；同时冯娜律师代理查明的事实链条显示：周某仅收固定收益、不参与经营、不担经营风险，担保人另行出具连带保证。法院认定该协议名为投资实为借贷，判令公司偿还本金50万元及利息7.2万元，担保人承担连带责任，二审维持。样本的三步说理逻辑：收益方式固定且保底（排除共担风险）、不参与经营管理（排除股权/合伙属性）、有担保安排（强化借贷属性）——三个特征叠加，隐藏的借贷关系浮出水面，利率照样按借贷规则审查。企业间借贷的合规清单由此展开：金额与期限与企业经营需求匹配，避免“高息短期循环”的表象；资金来源合法（自有资金，套取金融机构贷款转贷的合同无效）；利率条款直接写明年化利率并对照签约时LPR四倍留出余量；预扣利息、保证金抵扣本金的操作不要做；担保结构与主合同的利率表述一致。超付利息的救济：已支付利息超过LPR四倍的，借款人可主张返还或折抵本金，这是企业对账时容易漏掉的一笔账。北京地区法院对企业间拆借与职业放贷的审查精细（出借频次、格式化合同、宣传推介痕迹都是职业放贷的认定要素），偶发拆借留好“为自身经营所需”的证据，别让正常周转被误伤。

IV. Practical Suggestions and Legal Basis

The first step is qualitative self-inspection: determine whether the lending is occasional or necessary for one's own business operations, and rule out the appearance of professional lending. The second step is interest rate compliance: set an upper limit equal to four times the one-year LPR at the time of signing the contract, and calculate the comprehensive cost by combining all fees. The third step is consistency of terms: avoid clauses stating guaranteed fixed returns in investment and cooperation agreements, and ensure that the name and content match. The fourth step is a closed-loop of evidence: keep records of loan notes, transfers, reconciliations, and collections throughout the entire process. Main legal basis: Article 667 (definition of loan contracts) and Article 680 (prohibition of usurious lending) of the Civil Code of the People's Republic of China (effective from 2021); the provisions on the upper limit of four times the one-year LPR and the determination of principal and professional lending in the "Interpretation of the Supreme People's Court on Several Issues Concerning the Application of Law in the Trial of Private Lending Cases" (second amendment in 2020); specific application shall be subject to the currently effective regulations.

5. Henglu Law Firm's Reminder

When lending between enterprises, remember two key points: for the validity of the loan, focus on "occasional needs + operational requirements"; for the interest rate, focus on the "cap of four times the LPR". Investment agreements with guaranteed returns will almost always be reinterpreted as loans in litigation, so they should be priced according to loan rules when signing.
