2.3 Ministry of Ecology and Environment (MEE)
MEE regulates environmental impacts through laws like the Environmental Protection Law and the Water Pollution Prevention and Control Law. Tanneries must comply with strict discharge limits for pollutants like chromium, sulfides, and organic compounds, driving investments in cleaner technologies.
2.4 National Standards of the People’s Republic of China (GB Standards)
GB standards are mandatory or voluntary technical specifications issued by SAMR. For the leather industry, key GB standards cover raw material quality, processing techniques, product performance, and safety requirements. Examples include:
-
GB/T 16799-2018: Leather—Physical and mechanical tests—Determination of tear load (tensile strength, elongation, etc.).
-
GB 20400-2006: Leather and fur—Limit of harmful substances (restrictions on formaldehyde, azo dyes, and heavy metals).
-
GB/T 39372-2020: Technical specification for green design product evaluation—Leather products.
3. Technical Standards: Ensuring Quality and Performance
China’s leather specifications emphasize both functional performance and consumer safety. These standards are aligned with international benchmarks set by organizations like the International Organization for Standardization (ISO) and the European Committee for Standardization (CEN), facilitating exports to global markets.
3.1 Raw Material Specifications
Raw hides and skins, primarily sourced from cattle, sheep, goats, and pigs, must meet stringent criteria for freshness, thickness, and defect levels. Standards such as GB/T 14629-2018 (Hides and skins—Grading) classify materials based on origin, size, and quality, ensuring consistency in downstream processing.
3.2 Processing and Tanning Standards
Tanning—the process of converting raw hides into durable leather—is critical for determining final product properties. Chinese standards regulate tanning methods (e.g., chrome tanning, vegetable tanning, synthetic tanning) and their associated parameters:
-
Chemical Usage: Limits on toxic chemicals like hexavalent chromium (a carcinogen) are enforced under GB 20400-2006. Chrome tanning, which accounts for ~80% of China’s leather production, requires strict control of Cr(III) concentrations (≤3 mg/kg in finished leather).
-
Process Efficiency: Guidelines promote water recycling and energy conservation, with targets for reducing wastewater discharge per ton of leather (e.g., ≤50 m³/ton under advanced treatment systems).
3.3 Finished Product Standards
Finished leather products (e.g., shoes, bags, upholstery) must comply with performance tests for durability, flexibility, and resistance to wear. Key metrics include:
-
Tensile Strength: Minimum values vary by application (e.g., 15 N/mm² for shoe uppers vs. 10 N/mm² for garments).
-
Color Fastness: Resistance to rubbing, washing, and light exposure (tested via ISO 105-B02 for color fading).
-
Abrasion Resistance: Measured using devices like the Martindale abrasion tester (e.g., ≥20,000 cycles for high-end furniture leather).
4. Environmental and Safety Regulations
Environmental sustainability is a top priority in China’s leather industry, driven by public health concerns and international pressure. Key regulations focus on pollution prevention and resource efficiency:
4.1 Pollutant Discharge Standards
MEE’s Discharge Standard of Water Pollutants for Tannery Industry (GB 30486-2013) sets strict limits on pollutants in wastewater, including:
-
Chemical Oxygen Demand (COD): ≤100 mg/L (advanced treatment required for some regions).
-
Total Chromium: ≤1.5 mg/L.
-
Sulfide: ≤0.5 mg/L.
Tanneries must install wastewater treatment plants (WWTPs) with technologies like reverse osmosis, activated carbon adsorption, and biological treatment to meet these standards. Non-compliant facilities face fines, shutdowns, or license revocation.
4.2 Restricted Substances
To protect consumers, China bans or restricts hazardous chemicals in leather products. The GB 20400-2006 standard prohibits:
-
Formaldehyde: ≤75 mg/kg (for direct skin contact products like gloves).
-
Azo Dyes: Any dye that releases carcinogenic aromatic amines (e.g., benzidine).
-
Heavy Metals: Lead (≤90 mg/kg), cadmium (≤75 mg/kg), and mercury (≤60 mg/kg).
These restrictions align with the EU’s REACH regulation and the U.S. Consumer Product Safety Improvement Act (CPSIA), simplifying export compliance.
4.3 Occupational Health and Safety
The Law on Work Safety mandates safe working conditions in tanneries, including ventilation systems to reduce exposure to toxic fumes (e.g., hydrogen sulfide) and personal protective equipment (PPE) for workers handling chemicals. Regular audits by MEE and local labor bureaus ensure adherence.
