Sinosure: Buyer Credit Limits, the Cost of Payment Terms and Subrogation on Default

Concept

Sinosure is China's state export credit insurer, and its place in a transaction is described wrongly almost everywhere. The policyholder and the claimant is the supplier, but the credit assessment is run on the buyer: the insurer approves a limit on a named importer (买方信用限额), and only inside that limit does the factory ship on open account. That gives the direct answer to the question this topic turns on — payment terms are not won by persuasion or by order size, they are won because a Sinosure limit is open on your company. The limit is an asset the importer manages although it is held in someone else's name, and a profile built once works across every purchase in China.

The asset has a second side that appears neither in sales material nor in most English-language coverage. On non-payment the supplier files a loss, Sinosure indemnifies it up to 90% and by subrogation takes over collection from the buyer — now as a Chinese state institution, with a database of 490 million enterprises and banks (SINOSURE Profile) and a network of overseas agents. The counterparty across the table changes within two to three weeks of the missed date, and the new one has no authority to discount principal.

What follows is the insurer's own domain. Documentary instruments and renminbi settlement sit in trade finance; the price of money and credit arbitrage in corporate lending.

The institution: who ends up as your creditor

Sinosure is the sole authorised operator of China's policy export credit insurance, incorporated on 18 December 2001 as a state-owned insurance company with its own legal personality.

Its shareholder and sponsoring department is the Ministry of Finance; prudential supervision sits with the NFRA (NFRA supervisory measures on Sinosure). Article 64 of those measures exempts policy insurance whose risk is carried by the state budget from contributions to the Insurance Security Fund. Insured volume across all lines reached $1,021.4 billion in 2024, up 10% year on year, across 227,000 clients (SINOSURE); in the first half of 2025 the insurer covered 27.4% of Chinese exports (Sina Finance, 23 March 2026); according to the Berne Union its total insured amount has ranked first among ECA members since 2015 (Trade Finance Global). Practically every fourth shipment out of China moves with a state insurer standing behind the seller.

The product range: whose loss gets paid

Sinosure's products differ less in the risks they list than in who receives the money — the exporter, the lending bank or the investor.

Indemnity percentages come from Sinosure's own product pages: short-term, medium and long-term, investment.

Short-term comprehensive export credit insurance (短期出口信用保险) is the policy your shipment moves under. One asymmetry matters: if the buyer, or the issuing bank under a documentary credit, is registered in China, political risks are not covered at all. Excluded are exchange-rate losses, the exporter's own breach, exports to affiliated companies, documentary discrepancies under letters of credit, and continued shipment after the exporter knew of the risk (wording 4.0, Ningxia edition, PDF). Four provisions reach the buyer directly. Where part of the export is deliberately left undeclared, the insurer is entitled to cut the indemnity percentage or decline liability across every shipment under the policy (article 6). Article 20 bars parallel cover of the same shipments with Coface or Allianz Trade without the insurer's written consent. Article 24 imposes confidentiality on buyer information — which is why the factory will not tell you what limit you carry. Article 22 requires the insurer's prior written consent to any change in the payment date, and moving a payment "by email" entitles the insurer to cut the indemnity or decline it. The wording exists in more than 30 non-identical provincial editions (register).

The 2026 generation. 普惠定额保险 and 普惠随心保险, published 14 April 2026, are sold only through the self-service portal, with automated underwriting and no buyer credit limit (PDF); the claim filing window is two years instead of four months, assessment takes 60 days, payment 10 days; collection costs sit with the insurer in full (clause 6.7.3), while court, arbitration and legal fees are advanced by the exporter itself (clause 6.5.2) and reimbursed only where it wins and the loss is covered. Payment terms here are possible without a credit check on the buyer — but the sanctions clause is broad.

Cover of costs, not of debt. 出口前保险 rev. 2026 (11 December 2025) reimburses production cost where the contract becomes impossible to perform, and liability starts from the date the trade contract takes effect (PDF). 特定合同保险 rev. 2025 covers both costs and receivable and adds the buyer's breach of contract and termination for convenience (PDF) — a cancelled order after production has started becomes an insured event.

Buyer's credit insurance explains the cheapness of Chinese project finance: the insured is the bank, principal and interest are covered with penalty interest excluded, and there are only two exclusions — the bank's own fault and risks outside the schedule. There is no trade-dispute clause and no documentary-discrepancy clause, and the waiting period is 90 days (出口买方信贷保险单, 2022 rev, PDF). Supplier's credit insurance (March 2018) covers the exporter or contractor, separating advance from deferred payments, with a 90% maximum (PDF).

Investment, domestic trade, guarantees. 海外投资保险 rev. 2025 (27 August 2025) exists in an equity form and two debt forms; the breach-of-undertaking risk requires a final and binding court or arbitral decision for a specified amount, and clause 7.1.2 fixes the premium rate for the life of the policy regardless of any deterioration in the host country's risk (PDF). 国内贸易信用保险 rev. 2024 covers domestic Chinese receivables up to one year, but only against insolvency and protracted default. Published tariffs exist only for guarantees: financial 1% per annum, bid 0.2%, payment 0.6% (09.2025).

The buyer credit limit

A credit limit is Sinosure's decision on the maximum single exposure to a named buyer, outside which no cover exists.

The rev. 4.0 rule is hard: with no limit in force on the shipment date, the insurer does not answer for that export at all — not "in part". This is the source of the familiar scene in which a factory ready to ship on credit yesterday demands prepayment today.

Procedure. The supplier files the application, separately for each buyer. Sinosure runs an investigation on its own database of 490 million enterprises and banks, its credit bureau subsidiary 中国信保资信有限公司 (SinoRating) and 400-plus information channels. The outcome is recorded in a Credit Limit Approval Notice (信用限额审批单) — and here sits the detail missing from every survey: the indemnity percentage set at limit approval prevails over the percentage in the policy schedule. The published "90%" is a ceiling; the operative rate is set buyer by buyer, and only for shipments made after the limit takes effect.

From the buyer's side the steps are: move to open account under cover; register with the SinoRating bureau and obtain an identifier with a credit report; give the factory constitutional documents, two years of accounts and a payment history — the point at which audit inside the Chinese perimeter stops being a formality. Industry reference points (estimate): turnover from $1 million a year, one completed financial year, profitability, no arrears; investigation up to 21 days; an opening limit of the order of $100,000.

The limit revolves — it frees up again as the receivable is repaid, so it expresses single exposure rather than annual turnover. Four things cancel it: a long dormant period with no declarations; the filing of a Notice of Possible Loss on that buyer, automatically; a material change in risk; and adjustment to actual utilisation.

The hidden lever. Approving a limit is not a purely credit decision: provincial agreements set a target "limit satisfaction ratio" (限额满足率), and the notice issued by the Tibet AR Department of Commerce and the Sichuan branch on 16 June 2026 (published 22 June 2026) requires it to be held at no less than 85% (swt.xizang.gov.cn), while MOFCOM's notice of 27 March 2026 speaks of "optimising the supply of limit resources". The policy provides no formal appeal. The working route after a refusal is different: refile with an expanded file and a SinoRating report, and on a systemic refusal, escalation by the supplier through the local commerce department that carries the 满足率 target.

What deferred payment actually costs

The real interest rate on the transaction is the supplier's mark-up for the delay, not the Sinosure premium: the premium is measured in fractions of a percent, the mark-up in percent.

The formula. If the contract price on prepayment is P and, for D days of credit, the factory asks P × (1 + m), then you are borrowing P and paying P × m for it. The effective annual rate is r = m × 360 / D.

The benchmarks: the weighted average rate on newly issued corporate loans in China is 3.04% per annum (June 2026, PBoC Q2 2026 monetary policy report, PDF) with the LPR at 3.00% at the fixing of 20 August 2026 (NIFC); dollar trade finance runs at 5.2–6.2% as of September 2026 (estimate); rouble working capital at 18–25% (estimate; the analysis sits in china-lending).

Arithmetic on a live transaction. A $500,000 contract, 120 days of credit, a 2% mark-up: that is $10,000, or 2% × 360 / 120 = 6.0% per annum. A yuan loan at 3.04% over the same 120 days would cost $5,067. The $4,933 difference buys you the absence of a Chinese entity, of collateral and of a bank credit file.

What the delay costs the factory. Its own cost of money is the same 3% per annum, around 1.0% of the contract over 120 days, plus the premium. The documented reference point is the 小微企业信保易 product as published by Sinosure in 2012: the rate fell as low as 0.13%, and the worked example published by Sinosure produced 0.2% of the prior year's customs export value (js.sinosure.com.cn, 2012); the current tariff edition is not publicly confirmed. An honest cost of a 120-day deferral is 1.15–1.25% of the contract (estimate); everything above that is margin. For a share of factories the premium is zero: local governments buy cover in bulk through 政府统保平台 umbrella platforms — Shenzhen exempts exporters with turnover up to $8 million (programme), and Panyu in 2026 up to $10 million (163.com).

The policy as collateral: how banks plug in

A Sinosure policy becomes bank collateral only through a tripartite structure — a bilateral assignment of policy rights is legally void against the insurer.

Assignment of insurance proceeds (转让赔款权益): the exporter remains the insured, but a tripartite agreement is signed between exporter, bank and Sinosure under which the insurer pays the financing institution directly and in full (Shanghai Financial Regulatory Bureau). The anchor is article 28 of rev. 4.0, under which an assignment or pledge of policy rights without Sinosure's written consent has no effect. The bank as the insured: bank policy 2.0 covers purchased receivables up to 180 days — unencumbered, with notice of assignment served on the buyer, and undisputed — or forfaiting, a non-recourse purchase of the claim with a participation up to 95%. For the bank the second structure is the stronger one: it does not depend on the exporter's declaration discipline.

By the end of 2021 some 300 banks had financed more than 4 trillion yuan against Sinosure policies (Trade Finance Global); the most active are CCB with its 信保贷 product, ICBC and Ping An Bank (the six-step process). No bank publishes an advance rate against the invoice; the ceiling is set by the indemnity percentage. For the buyer this yields a concrete argument: a factory that has assigned its policy rights to a bank is paid at shipment, not 120 days later, so a mark-up "for tying up working capital" has no basis. Bank appetite is set out in the survey of Chinese banks, payment routes in paying Chinese suppliers.

Claim, subrogation, collection

Subrogation is the transfer to Sinosure of the claim against the buyer to the extent of the indemnity paid; after payment your creditor is a Chinese state insurer, not the factory.

The average time to close a case for micro and small enterprises is 13.4 days, and the "48 hours" quoted in marketing material is a 2025 record rather than a service standard (People's Daily Overseas Edition, 26 June 2026).

After payment the exporter assigns its contractual rights to Sinosure, and any sums it receives from the buyer are treated as held on the insurer's behalf. A mandatory order-of-application rule applies: once the risk has materialised and before indemnity is paid, the buyer's payments discharge debt in order of payment date, oldest first, whatever the parties may have agreed — which shuts down the practice of booking a payment against the newest shipment. The indemnity is repayable with interest if undisclosed security or a trade dispute comes to light, or if the exporter granted a discount on its own initiative. Hence the consequence usually missed: once the loss notice has been filed, the factory has no legal standing to agree a write-off with you.

How collection runs. The forums are the Chinese courts, including attachment and preservation measures, and arbitration, primarily CIETAC; abroad, Sinosure relies on the New York Convention. The pressure points inside China are the debtor's trademarks and patents, its accounts and receivables, inventory, moulds and tooling, and future shipments; an exit ban on the debtor's representatives is also reported (Harris Sliwoski / Mondaq, 27 July 2026). The insurer does not reduce principal — concessions are available on timing and on the removal of unjustified charges, which is consistent with the policy mechanics, since an unauthorised reduction of the claim triggers clawback of the indemnity. Separately there is the double payment trap: where Sinosure has already paid the supplier, a payment made directly to the factory will most likely not discharge the insurer's claim, and a settlement requires a bilingual PRC-law agreement executed under company chop with releases from every holder of the claim (Harris Sliwoski).

Why shipments with a probable goods dispute do not belong under cover. The policy contains no "quality dispute" exclusion, but the 贸易纠纷 (trade dispute) construct operates as a deferred exclusion with the broadest possible definition — any dispute capable of affecting the establishment and enforcement of the claim against the buyer. Where one exists, Sinosure determines liability itself, and if the exporter disagrees the insurer requires it to litigate or arbitrate in the buyer's country and obtain a final and binding decision before settlement proceeds, with the costs advanced by the exporter. The lever of withholding payment until a defect is remedied does not work here: withholding qualifies as protracted default, triggers the loss notice, cancels the limit and moves the dispute into collection by an insurer indifferent to the quality of the goods. Acceptance has to be closed before the payment date, and disputed shipments and first shipments from a new factory belong under a letter of credit. Case law on the adjacent ground of refusal — shipment after knowledge of the risk — is inconsistent: the Qianhai court in (2018)粤0391民初319号 treated a first missed payment as sufficient, while the Chongqing High Court in (2019)渝民申2769号 required evidence of deteriorating creditworthiness (AnJie Broad, 22 October 2024).

Sanctions perimeter and country restrictions

Sanctions protection under a Sinosure policy depends not on the company's stance but on which product was bought and in which year — there is no single regime.

There are three regimes, and conflating them is the standard error. The flagship rev. 4.0 wording contains no sanctions clause at all. The April 2026 products contain the widest possible one: payment must not breach UN resolutions or the trade and economic sanctions or anti-sanctions rules of China or of any other jurisdiction, plus a separate exclusion of countries named in a list annexed to the policy. Overseas investment insurance rev. 2025 contains an inverted clause: sanctions against the host country that block currency conversion are covered, except for sanctions imposed by the Chinese government, in which it participates or which it has undertaken to observe — meaning the instrument hedges Western sanctions effects and by design does not work against measures Beijing recognises.

Country exclusions. The documented primary list is the exclusion schedule of the 小微企业信保易 product as published by Sinosure in 2012: Cuba, Iran, Sudan, South Sudan, Libya, Côte d'Ivoire, Yemen, Syria, Afghanistan, Iraq, Somalia, Burundi, Chad, Comoros, DR Congo, Eritrea, Guinea-Bissau, Liberia, Rwanda, Sierra Leone, Zimbabwe and the State of Palestine (js.sinosure.com.cn, 2012); the current edition of that schedule is not publicly confirmed and it cannot be read as a live 2026 list. The "Sinosure country blacklist" of roughly 35 states that circulates online is described as speculative by its own author (Harris Sliwoski). In law there is no blacklist as a public institution: country access is set by the 短期险国家（地区）分类表, the non-public country classification table supplied with the policy, and by internal country underwriting policy mandated by article 31 of the NFRA measures. The country risk scale runs to nine grades; the 21st edition of the Country Risk Analysis Report was published on 20 October 2025 (Wuhan Financial Bureau).

How a country filter works in practice. The best-documented case is the Russian perimeter, and it shows the mechanism rather than an exception to it. Russia does not appear on the documented exclusion list, no public act terminating cover of Russian risk exists in open sources, and 2024 reports of refusals in the Russian business press are unsupported by a primary document and have not been updated since. The mechanism needs no public act: it runs through the non-public country classification, underwriting policy under article 31 of the NFRA measures and an unreasoned decision on the limit — which presents to the buyer as a refusal without stated grounds and a factory demanding prepayment or a confirmed letter of credit. The second layer is the sanctions clause in the 2026 products, which refers to the rules of any jurisdiction and allows a claim to be declined after the goods have shipped. The third is counter-sanctions: article 24 of the State Council regulation on outbound investment, in force from 1 July 2026, refers to the PRC Anti-Foreign Sanctions Law (Sinosure). The same three layers apply to any destination an underwriter treats as elevated, which is why sanctions screening of the chain belongs before the limit application rather than after the refusal.

What changed in 2025–2026

Three things changed over two years: the supervisory regime, the insurer's capacity and the rules of access to cover for small business.

One gap is worth recording: national full-year figures for 2025 and first-half figures for 2026 had not been published as of September 2026, and the $565.6 billion figure that circulates in several write-ups relates to the first half of 2025, not to a full year.
