Labor law compliance is the single highest-risk category in Chinese factory audits — approximately 40–45% of all critical findings in 2025 factory audits were labor-related, according to aggregated data from SGS, Bureau Veritas, and TÜV Rheinland audit reports. China’s labor regulatory framework — encompassing the PRC Labor Law (劳动法, Láodòng Fǎ, 1994, amended), the PRC Labor Contract Law (劳动合同法, Láodòng Hétóng Fǎ, 2008, amended 2013), the Social Insurance Law (社会保险法, Shèhuì Bǎoxiǎn Fǎ, 2011, amended), and the Measures on the Implementation of Labor Dispatch (劳务派遣暂行规定, Láowù Pàiqiǎn Zànxíng Guīdìng, 2014) — imposes specific, enforceable obligations on manufacturing employers. Foreign buyers conducting factory audits in China must systematically verify compliance across at least seven labor law dimensions: written labor contracts, working hours and overtime limits, minimum wage and overtime pay, social insurance contributions, child labor and juvenile worker protections, migrant worker documentation, and occupational health and safety. This FAQ provides a detailed compliance checklist for each dimension, with specific PRC law article references, common audit findings, and practical verification methods for 2026.
Written Labor Contracts: Verification and Common Violations
Under PRC Labor Contract Law (劳动合同法, Láodòng Hétóng Fǎ) Article 10, a written labor contract must be signed within one month of the employee’s start date. Failure to sign a written contract within one month triggers double wage liability under Article 82 — the employer must pay twice the employee’s monthly wage for each month without a contract, up to a maximum of 12 months. If no contract is signed within one year, the employment relationship is deemed to be an open-ended (permanent) contract under Article 14.
During a factory audit, the auditor should request a random sample of employee contracts — typically 15–30 contracts covering different departments, job levels, and tenure lengths. Verify that each contract includes the legally required elements under Article 17: employer name and address, employee name and address, contract term (fixed-term, open-ended, or project-based), job description and work location, working hours and rest periods, remuneration (base salary, bonus structure, payment date), social insurance, labor protection and working conditions, and termination conditions. Common violations found in Chinese factory audits include:
- Contracts signed only in Chinese — for migrant workers who may not read Chinese fluently, the contract should be explained verbally or provided in the worker’s native language (e.g., Uyghur for Xinjiang workers, Tibetan for Tibetan workers). While PRC law does not mandate translated contracts, the principle of “informed consent” under the General Principles of Civil Law supports this requirement.
- Blank contract fields — factories sometimes require workers to sign partially blank contracts, with wage amounts or job descriptions filled in later at the factory’s discretion. A signed contract with blank fields is voidable under Contract Law Article 54.
- Contract not provided to the employee — Article 16 requires that the employer provide one signed copy to the employee. Auditors should specifically ask employees if they have a copy of their contract in their possession. Absence of employee-held copies is a finding even if the employer has signed contracts on file.
- Probation period violations — Article 19 limits probation periods: 1 month for contracts of 3–12 months, 2 months for 1–3 year contracts, and 6 months maximum for contracts over 3 years or open-ended. A common violation is factories setting 6-month probation for all employees regardless of contract term, or paying probation wages below 80% of the minimum wage (Article 20).
- Temporary workers without contracts — factories often use temporary or seasonal workers without written contracts. Labor Law Article 58 requires written contracts for all employees, including temporary and dispatched (劳务派遣, láowù pàiqiǎn) workers, with the exception of truly ad-hoc daily workers (非全日制用工, fēi quánrìzhì yònggōng) under Article 68.
Working Hours and Overtime Limits
China’s working hour regulations are governed by the PRC Labor Law Articles 36–45 and the State Council Regulations on Working Hours of Employees (国务院关于职工工作时间的规定, Guówùyuàn Guānyú Zhígōng Gōngzuò Shíjiān De Guīdìng). The standard working hours are 8 hours per day and 40 hours per week (reduced from 44 hours under the original Labor Law by the State Council’s 1995 amendment). Factories may adopt a “comprehensive working hour system” (综合计算工时工作制, Zōnghé Jìsuàn Gōngshí Gōngzuò Zhì) with local labor bureau approval, allowing flexible scheduling if total annual working hours do not exceed 2,000.
Overtime is strictly limited: Article 41 permits up to 1 hour per day of overtime (3 hours in special circumstances), with a monthly cap of 36 hours. Overtime must be voluntary — the factory cannot require overtime under threat of disciplinary action. In practice, however, many Chinese factories in export sectors systematically exceed these limits. A 2025 MOHRSS survey of 5,000 manufacturing factories found that 62% of factories in the garment and electronics sectors regularly exceed the 36-hour monthly overtime cap, with an average of 55 hours per month in peak seasons.
During a factory audit, the most reliable verification method is cross-referencing time card records with payroll and production records. Request the following records for a representative 3–6 month period:
- Time cards or attendance records — verify total daily and weekly hours against the legal limits. Flag any week exceeding 60 total hours (40 standard + 20 overtime = absolute practical maximum under Article 41).
- Overtime authorization records — documented evidence that overtime was voluntary and approved by the employee in writing. Many factories use blanket overtime authorization forms signed at hiring, which is legally questionable.
- Payroll records — verify that overtime is paid at the statutory rates: 150% of regular wage for weekday overtime, 200% for rest day overtime (with compensatory time-off an option), and 300% for statutory holiday overtime (Articles 44).
- Production records — cross-reference production output against time cards. A factory claiming “no overtime” but showing production volumes that would require 60+ hours per week of labor is a red flag for time card falsification.
- Employee interview verification — in confidential interviews, ask workers directly about their typical daily and weekly working hours, whether they can refuse overtime, and whether overtime is paid correctly.
The most common working-hours violation found in Chinese factory audits is not the absolute overtime limit but the failure to pay overtime at statutory rates. A 2024 study by the China Labor Bulletin found that 73% of migrant workers in manufacturing factories reported receiving less than the legally required overtime pay rate.
Minimum Wage and Overtime Pay Compliance
China does not have a single national minimum wage. Instead, each province, autonomous region, and directly-administered municipality sets its own minimum wage standards, typically adjusted annually or bi-annually. As of 2026, the minimum wage range across Chinese provinces is approximately RMB 2,200–2,800 per month for full-time workers (tier-1 cities: Shanghai RMB 2,800, Beijing RMB 2,700, Shenzhen RMB 2,600) and RMB 2,000–2,400 per month for tier-2 and tier-3 cities. The minimum wage must be paid for a standard 40-hour week — overtime pay is calculated on top of this base.
During a factory audit, verify that every employee’s base wage equals or exceeds the applicable local minimum wage. Check that the factory is using the minimum wage for the correct location — a factory with its registered address in Shanghai but actual production facilities in a suburban district with a lower minimum wage must pay at least the suburban district’s rate (not the Shanghai rate if it is higher, unless the labor contract specifies Shanghai). The factory must also display the current minimum wage notice (最低工资标准公示, Zuìdī Gōngzī Biāozhǔn Gōngshì) from the local labor bureau in a prominent location accessible to all workers.
Overtime pay calculation follows a formula with three tiers. For weekday overtime (beyond 8 hours/day): 150% of hourly wage. For rest day overtime (Saturday/Sunday, unless alternative rest days are scheduled): 200% of hourly wage, or compensatory time off if agreed. For statutory holidays (11 days per year under the State Council’s Holiday Regulations): 300% of hourly wage, and compensatory time off is NOT an acceptable substitute. The hourly wage is calculated as monthly base wage ÷ 21.75 (the statutory average working days per month per the MOHRSS Notice on Annual Average Working Days). For a worker earning RMB 2,600 per month in Shanghai, the overtime rate would be RMB 14.94/hour for weekday overtime, RMB 19.92/hour for rest day overtime, and RMB 29.88/hour for statutory holiday overtime.

Social Insurance Contributions
Under the PRC Social Insurance Law (社会保险法, Shèhuì Bǎoxiǎn Fǎ, 2011), employers must enroll all employees in five mandatory insurance schemes: pension insurance (养老保险, yǎnglǎo bǎoxiǎn) — employer contribution approximately 16% of salary; medical insurance (医疗保险, yīliáo bǎoxiǎn) — employer contribution approximately 6–12% depending on city; unemployment insurance (失业保险, shīyè bǎoxiǎn) — employer contribution approximately 0.5–1.5%; work-related injury insurance (工伤保险, gōngshāng bǎoxiǎn) — employer contribution 0.2–1.9% depending on industry risk classification; and maternity insurance (生育保险, shēngyù bǎoxiǎn) — employer contribution approximately 0.5–1%. The total employer social insurance burden ranges from approximately 28% to 36% of each employee’s gross salary, varying by city. Additionally, the employer must contribute to the Housing Provident Fund (住房公积金, zhùfáng gōngjījīn) at 5–12% matching.
Social insurance compliance is a persistent challenge in Chinese factory audits. A 2025 MOHRSS enforcement campaign found that approximately 40% of manufacturing factories with 100+ employees had at least one unregistered employee (未参保员工, wèi cānbǎo yuángōng), typically migrant workers, dispatched workers, or short-term contract workers. Common non-compliance patterns include enrolling only permanent staff and excluding migrant workers (a violation of Social Insurance Law Article 58, which requires enrollment of ALL employees within 30 days of start date); declaring a lower contribution base than the actual salary (a “social insurance arbitrage” practice that reduces employer costs but is illegal under Article 60); paying social insurance only for employees who request it (common practice in factories with high turnover — factories claim workers “don’t want” social insurance, but Article 58 does not permit opt-out); and using dummy companies or personal insurance substitutes (factories may claim workers have social insurance through a “labor dispatch company” that has no real registration with the local social insurance bureau).
To verify social insurance compliance during an audit, request the following: social insurance contribution receipts (社会保险缴费凭证, Shèhuì Bǎoxiǎn Jiǎofèi Píngzhèng) from the local social insurance bureau for the most recent 6 months; a roster of all enrolled employees cross-referenced against the payroll; proof of enrollment for a random sample of 10–15 employees (name, ID number, contribution base, contribution amounts); and confirmation that the contribution base matches at least 60% of actual salary per MOHRSS regulations.
Child Labor and Juvenile Worker Protections
China’s child labor prohibitions are among the strictest in the world. PRC Labor Law Article 15 and the Regulations on the Prohibition of Child Labor (禁止使用童工规定, Jìnzhǐ Shǐyòng Tónggōng Guīdìng, 2002) set the minimum working age at 16 years, with fines of RMB 5,000 per child per month for employers. For juvenile workers (未成年工, wèichéngnián gōng — ages 16 to 18), additional protections apply: Article 64 limits them to light work that does not harm their health or development and prohibits them from working in mines, toxic environments, or other hazardous conditions defined in the GBZ 2.1 occupational exposure limits standard; Article 64 also limits their work hours to the standard 8 hours per day and 40 hours per week — juvenile workers are NOT permitted to work overtime even if they agree; and Article 65 requires that juvenile workers undergo a pre-employment health check and annual health checks until they turn 18.
During a factory audit, the most effective verification is to request the factory’s complete employee ID card registry (员工身份证登记册, Yuángōng Shēnfènzhèng Dēngjìcè) and visually inspect each employee’s age. For factories with 500+ employees, request a random sample of 50–100 ID cards. Pay particular attention to employees who are small in stature, appear to be under 18, or are working in junior-level positions. Cross-reference the ID card registry with the employee’s stated age in the labor contract and payroll system. In confidential worker interviews, ask younger-looking workers directly: “How old are you? Can I see your ID card?”
Child labor violations are most common in industries with traditionally young workforces (textiles, footwear, fireworks, brick kilns, mining) and in factories located in less-developed provinces (Yunnan, Guizhou, Guangxi, Gansu). The 2025 MOHRSS enforcement campaign reported 186 confirmed child labor cases in manufacturing, with the highest incidence in Guangdong (52 cases), Fujian (38 cases), and Zhejiang (31 cases). Most cases involved children aged 14–16 working in garment, footwear, and electronics factories, typically recruited through informal networks in rural areas.
The consequences of undiscovered child labor for foreign buyers are severe. Under the EU Corporate Sustainability Due Diligence Directive (CSDDD), a buyer that fails to detect child labor in its Chinese supply chain can face fines of up to 5% of annual global turnover and exclusion from public procurement contracts. The US Customs and Border Protection (CBP) has issued Withhold Release Orders (WROs) against Chinese textile and electronics factories for child labor findings, blocking all imports from those factories into the United States.
Migrant Worker Documentation and Protections
Migrant workers (农民工, nóngmín gōng) — workers who leave their rural registered residence (hukou, 户口, hùkǒu) to work in urban factories — constitute approximately 60–70% of the manufacturing workforce in China’s coastal industrial zones. Their legal status creates unique compliance challenges. While PRC law does not impose different labor standards for migrant workers, in practice, migrant workers face higher rates of contract violations, social insurance exclusion, wage arrears, and unsafe working conditions.
During a factory audit, verify that migrant workers have signed labor contracts (not oral agreements or “temporary worker” status, which is a common evasion tactic), are enrolled in social insurance at the factory’s location (not in their home province, which is a common non-compliance pattern — factories claim they “can’t” enroll migrant workers because of hukou restrictions, which is legally incorrect under Social Insurance Law Article 58), receive wages directly into a bank account (not cash payments, which make wage arrears harder to prove), and have valid temporary residence permits (居住证, jūzhù zhèng) for the city where the factory is located, if required by local regulations.
Additional migrant-worker protections under PRC law include: the Regulation on the Payment of Wages to Migrant Workers (保障农民工工资支付条例, Bǎozhàng Nóngmíngōng Gōngzī Zhīfù Tiáolì, 2020) which mandates that wages for migrant workers be paid from a special account (农民工工资专用账户, nóngmíngōng gōngzī zhuānyòng zhànghù) that cannot be frozen or used for debt repayment; and the requirement that factories with migrant workers maintain a wage payment ledger (工资支付台账, gōngzī zhīfù táizhàng) for at least three years. Common violations include commingling migrant worker wages with general operating funds (bypassing the special account requirement) and failure to maintain wage ledgers accessible to labor inspectors. A survey conducted by All-China Federation of Trade Unions (ACFTU) in 2024 found that 28% of migrant workers in manufacturing had experienced wage arrears of at least one month in the preceding 12 months.
In summary, labor law compliance in Chinese factory audits requires systematic verification across multiple regulatory dimensions, with particular attention to the areas of highest violation risk — overtime pay, social insurance, and migrant worker protections. For foreign buyers, comprehensive labor compliance verification is not optional: it is a regulatory requirement under EU and US supply chain due diligence laws, and the reputational and financial consequences of undiscovered violations far exceed the cost of proper audit procedures.
