China’s green courier packaging regulations: sustainable shipping with less waste, less plastic tape & less materials

China’s express delivery industry, handling over 100 billion parcels annually, is undergoing a green transformation with the introduction of “Requirements for Restricting Excessive Packaging in Express Delivery”. Set to take effect on July 1, 2026, these regulations aim to curb waste, reduce pollution, and promote sustainable logistics. This article breaks down the key policies, technical requirements, and compliance strategies outlined in the new standards and supplementary guidelines.

Core Objectives of the Regulations

The regulations focus on three pillars:
1. Reduction: Minimize packaging layers and material use while ensuring product safety.
2. Non-Toxicity: Comply with GB 43352 to limit heavy metals and hazardous substances in packaging materials.
3. Collaboration: Encourage upstream-downstream coordination to adopt “original packaging” (pre-approved designs that eliminate secondary packaging).

Key Technical Requirements

1. Packaging Size Optimization
• “Bounding Box” Rule: Packaging size must not exceed 1.5–2.5 times the diagonal length of the item(s) being shipped, measured via a “minimum bounding box” method (see Figure 1).
• Box Classification: Seven standardized box types (1–7) are defined by maximum load capacity (3kg–50kg) and internal dimensions (450mm–2500mm). Shipments over 30kg require reinforced strapping.
•
2. Layer Restrictions
• Non-Fragile Items (e.g., clothing, electronics): ≤2 layers.
• Fragile Items (e.g., glass, ceramics): ≤3 layers.
• Perishables (e.g., cold-chain foods): ≤4 layers.
Note: Fillers like bubble wrap only count as a layer if fully enclosing the product.

3. Tape Usage Limits
• Length Caps: Tape usage must not exceed 3–5 times the box’s perimeter, depending on size (see Table 4). Exceptions allow double the limit for fragile/high-value items.
• Width Limit: ≤45mm.
• Preferred Alternatives: Degradable tape or tape-free designs (e.g., self-sealing boxes).

Supplementary Guidelines for Implementation

The supporting document Packaging Tape Usage Requirements clarifies practical applications:
• Box Types & Encapsulation Methods:
– Small boxes (Types 1–2): “一”字形 (single-strip) taping, ≤1.5× internal dimensions.
– Medium boxes (Types 3–5): “十”字形 (cross) taping, ≤2.5× internal dimensions.
– Large boxes (Types 6–7): “艹”字形 (double-cross) taping, ≤4× internal dimensions.
• Prohibitions: Tape cannot be applied to pre-sealed envelopes/bags with adhesive functions.

Compliance Verification Methods

The standards mandate precise measurement protocols:
• Item Dimensions: Use calipers/automated tools to measure the “bounding box” diagonal (average of 3 readings).
• Tape Length: Measure along the applied path, rounded to the nearest mm.
• Tolerance: ≤5% deviation in repeated tests.
Non-compliance: Any violation of the above rules classifies packaging as “excessive,” subject to penalties.

Industry Implications

1. Operational Shifts: Logistics providers must adopt size-matching algorithms and layer-counting systems.
2. Material Innovation: Demand for biodegradable fillers (e.g., plant fiber) and thin-but-strong tapes will rise.
3. Costs: While compliant materials may cost 10–15% more upfront, reduced waste and penalties offset long-term expenses.

The new policies mark a decisive step toward sustainable logistics. By standardizing packaging practices, the regulations aim to cut waste by 30–40% in the express sector by 2030. Businesses should start auditing their packaging workflows now to ensure seamless compliance by the 2026 deadline.
