Introduction

Labor law compliance is one of the most sensitive and legally consequential dimensions of any Chinese factory audit. For foreign buyers, the stakes are high: labor violations in your supply chain can lead to reputational damage, regulatory penalties under modern slavery acts, import restrictions, and — in the worst cases — criminal liability. China’s labor laws have been significantly strengthened in recent years, with the 2018 amendments to the Labor Contract Law, stricter social insurance enforcement from 2020 onward, and ongoing reforms to working hour regulations for gig economy and platform workers that spill over into traditional manufacturing.

Yet many foreign buyers — especially those new to China sourcing — are uncertain about what exactly to check during a factory audit. They know “labor compliance” is important but lack a detailed checklist of what constitutes compliance under Chinese law. This article provides a comprehensive, actionable guide to the labor law compliance checkpoints you should verify in every Chinese factory audit.

1. Legal Framework Overview

Before diving into specific checkpoints, it helps to understand the legal framework that governs labor relations in Chinese factories:

• Labor Law of the PRC (劳动法, 1995, amended 2018): The foundational law governing working hours, rest periods, wages, occupational safety, and female worker protections.
• Labor Contract Law of the PRC (劳动合同法, 2008, amended 2018): Governs employment contracts, probation periods, termination, severance, and fixed-term vs. open-term contracts.
• Social Insurance Law of the PRC (社会保险法, 2011, amended 2018): Mandates employer contributions to pension, medical, unemployment, work-related injury, and maternity insurance.
• Regulations on Work-Related Injury Insurance (工伤保险条例): Defines employer obligations for workplace injury reporting, compensation, and prevention.
• Provisions on the Prohibition of Child Labor (禁止使用童工规定): Sets the minimum working age at 16 and prohibits employers from using child labor under any circumstances.
• Law on the Protection of Minors (未成年人保护法): Additional protections for workers aged 16–18, including restrictions on overtime, night shifts, and hazardous work.

2. Employment Contracts — The First Checkpoint

Chinese law requires that written labor contracts be signed within one month of the employee’s start date. During your audit, check the following:

• Do all workers have written contracts? Randomly sample 10–20 contract files from different departments. Check that contracts exist for all sampled workers. Missing contracts are one of the most common labor law violations found in Chinese factory audits.
• Are contracts in Chinese? While bilingual contracts are permitted, the Chinese-language version is the legally binding one. Foreign workers (if any) should have contracts in a language they understand, but the Chinese version governs.
• Do contracts specify the correct details? Verify that contracts include: worker name, employer name and address, job description, work location, working hours, wage amount and payment date, social insurance provisions, contract duration, probation period (maximum 6 months, and cannot exceed the contract duration), and termination conditions.
• Are there open-term contracts for long-service workers? Under Chinese law, after two consecutive fixed-term contracts or 10 years of service with the same employer, workers are entitled to an open-term (indefinite) contract. Check whether long-serving workers have been properly converted.
• Are probation periods legal? Probation cannot exceed one month for contracts of 3–12 months, two months for contracts of 1–3 years, and six months for contracts of 3+ years or open-term. Probation wages must be at least 80% of the regular wage and not below the local minimum wage.

3. Working Hours and Overtime Compliance

Working hour violations are arguably the most common labor law issue found in Chinese factory audits. The legal framework is clear, but enforcement has historically been lax in export-oriented manufacturing sectors.

3.1 Legal Standards

• Standard working hours: 8 hours per day, 40 hours per week (5-day work week).
• Overtime limit: Maximum 3 hours per day, 36 hours per month. Annualized averaging is not permitted for manufacturing workers.
• Overtime pay rates: 150% of regular wage for weekday overtime, 200% for weekends (or compensatory time off), 300% for public holidays.
• Weekly rest: Workers are entitled to at least one full day of rest per week (typically Sunday, but may be a different day depending on the factory’s schedule).

3.2 What to Check During the Audit

• Punch card records: Request the last 3–6 months of attendance records (punch cards, biometric logs, or timesheets). Calculate the daily and monthly overtime for a sample of workers. Compare with overtime pay records to verify that overtime is being compensated at the correct rate.
• Payroll vs. attendance cross-check: Factory A: attendance logs show 60 hours of monthly overtime per worker, but payroll only shows 36 hours of overtime pay. This discrepancy indicates that either overtime is being unpaid or the factory is running two sets of books.
• Realistic overtime patterns: If the attendance system shows exactly 36 overtime hours for every worker every month — suspiciously precise — the factory may be capping the recorded overtime at the legal limit while workers actually work more. Compare with production output data to see if the numbers are realistic.
• Worker interviews: Ask workers (privately, away from management) how many days per week they typically work, when their last day off was, and whether they feel able to refuse overtime. This is the most honest source of overtime data.

3.3 The “Two Records” Problem

It is well known in China sourcing circles that many factories maintain two attendance systems: one for internal management (showing actual working hours) and one for audit purposes (showing compliant hours). During your audit, ask to see real-time attendance data from the biometric system rather than printed summary reports. If the factory claims they cannot show you the live system, consider it a yellow flag and investigate further.

4. Wage Compliance

4.1 Minimum Wage

Every province and city in China sets its own minimum wage, typically updated every 1–2 years. In 2026, minimum wages range from approximately RMB 1,800/month in inland provinces to RMB 2,690/month in Shanghai. The minimum wage applies to full-time workers and includes basic salary but excludes overtime pay, bonuses, and benefits. Verify that the factory pays at least the local minimum wage for normal working hours before overtime is calculated.

4.2 Timely Payment

Chinese law requires wages to be paid at least once per month, on a regular date. Check whether the factory has ever delayed wage payments. During worker interviews, ask if wages are always paid on time. Wage arrears are a significant red flag — factories that delay wages are often in financial distress.

4.3 Payroll Records

Review payroll records for a sample of workers covering the last three months. Verify that: base wages meet or exceed the local minimum wage, overtime is calculated at the correct rates (150%/200%/300%), deductions (social insurance, individual income tax, housing fund if applicable) are itemized and legal, and workers receive pay slips (工资条) showing these details.

4.4 Equal Pay for Equal Work

Chinese law prohibits wage discrimination based on gender, ethnicity, or religious belief. While it is difficult to verify this in a single audit, check whether male and female workers performing the same job role appear to receive similar base wages. Significant unexplained disparities should be flagged.

5. Social Insurance Compliance

Chinese law requires employers to enroll workers in five social insurance schemes: pension (养老保险), medical (医疗保险), unemployment (失业保险), work-related injury (工伤保险), and maternity (生育保险). Many factories also contribute to the Housing Provident Fund (住房公积金), though this is technically separate from social insurance.

5.1 What to Check

• Enrollment records: Request a list of all workers enrolled in social insurance and compare it with the total workforce. Significant gaps indicate non-enrollment, which is a violation.
• Payment receipts: Ask to see recent social insurance payment receipts from the local social insurance bureau. These show whether contributions are being paid on time and in the correct amount.
• Probation period enrollment: Chinese law requires social insurance enrollment from Day 1 of employment — probation periods do not exempt the employer. Some factories incorrectly delay enrollment until after probation ends.
• Rural vs. urban workers: Some factories enroll rural migrant workers in a reduced social insurance scheme (城乡居民保险) instead of the standard urban employee scheme (城镇职工保险). While legally permitted in some provinces, this provides lower benefits. Check whether the scheme used matches the worker’s registered residence (hukou) type and preference.

5.2 The Social Insurance Challenge

In practice, full social insurance compliance is rare among small and medium Chinese factories. The cost — approximately 30–40% of the worker’s base salary on top of the gross wage — is a significant burden for labor-intensive manufacturers. Many factories offer a “social insurance allowance” (社保补贴) instead of actual enrollment, which is illegal but widespread. As a foreign buyer, you must decide your tolerance threshold: full compliance is the legal standard and should be required for strategic suppliers, while some buyers accept partial compliance (e.g., work-related injury insurance + medical, but not pension) for low-risk, transactional suppliers.

6. Child Labor and Forced Labor Prevention

6.1 Age Verification

Chinese law sets the minimum working age at 16. During your audit: request to see ID card copies for all workers hired in the past 12 months; verify that no workers were under 16 at the time of hire; and check for any workers aged 16–18 who should not be performing hazardous work, night shifts, or overtime.

6.2 Identity Document Verification

Some migrants use fake ID cards to obtain employment before age 16. The factory should have a system for verifying ID authenticity — either through the Ministry of Public Security’s online verification platform or by checking the card’s security features. Ask the factory manager what verification process they use.

6.3 Forced Labor Indicators

Check for these forced labor red flags: workers’ ID cards or travel documents held by the factory (illegal), recruitment fees charged to workers (common but prohibited under international standards), restrictions on freedom of movement (locked dormitories, guarded factory exits), and wage deductions as a form of punishment or debt bondage. If you find any of these during a walk-through, escalate immediately.

7. Worker Welfare and Dormitory Conditions

For factories that provide dormitories — common in China’s manufacturing regions — check the following during your facility walk-through:

• Dormitory occupancy: Are rooms overcrowded? A reasonable standard is 4–8 workers per room. Bunk beds should be stable, with adequate space between bunks.
• Sanitation: Are toilets and showers clean and functioning? Is there hot water? Are there separate facilities for male and female workers?
• Fire safety in dorms: Are there smoke detectors, fire extinguishers, and clear evacuation routes in the dormitory building? Are windows not barred — or if barred, are the bars openable from inside?
• Cafeteria: Is the cafeteria clean? Are workers provided with adequate meals? Is drinking water available?
• Medical facilities: Does the factory have a first-aid station or clinic? Are first-aid kits stocked and accessible?
• Worker grievance mechanism: Is there a system for workers to report complaints anonymously? Many factories have a suggestion box or a WeChat-based reporting channel. Check whether it is actually used and whether complaints are addressed.

8. Documentation Audit Checklist Summary

For quick reference, here is a summary of documents you should request during a labor compliance audit:

• Worker list (员工花名册) with ID numbers, hire dates, and positions
• Sample labor contracts (10–20 from different departments)
• Attendance/punch card records for the past 3 months
• Payroll records for the past 3 months
• Social insurance enrollment list and payment receipts
• Work-related injury records (accident reports, compensation records)
• Overtime approval records (if the factory claims a formal approval process)
• Worker training records (especially for safety and SOP training)
• Dormitory inspection records (if applicable)
• Worker grievance log (投诉记录)
• Collective bargaining agreement (if applicable, for unionized factories)

Conclusion

Labor law compliance is a critical component of any Chinese factory audit. The key checkpoints — employment contracts, working hours and overtime pay, wages, social insurance, child labor prevention, and worker welfare — form the backbone of a comprehensive social compliance assessment. While full compliance is challenging for many Chinese factories, particularly in labor-intensive sectors, foreign buyers have both a legal and ethical responsibility to verify and enforce minimum standards.

Remember: labor violations found in your supplier’s factory are not just the supplier’s problem. Under the US Uyghur Forced Labor Prevention Act, the EU Corporate Sustainability Due Diligence Directive, and similar legislation in other markets, importers are increasingly held accountable for labor conditions in their supply chains. Investing in thorough labor compliance audits is not optional — it is a legal requirement for responsible sourcing in 2026 and beyond.
