Ⅰ. Core industrial belts and regional advantages
1. Northern Manufacturing Center: Hebei/Shandong
Hebei (Shijiazhuang, Cangzhou, Baoding):
- Industry characteristics: government-supported labor protection industry cluster, strong price competitiveness, significant advantages in cotton spinning raw materials, focusing on low-end and mid-end workwear (cotton workwear, reflective vests, basic protective clothing)
- Typical products: anti-static clothing, winter plush workwear, ordinary one-piece workwear
Shandong (Qingdao, Weifang):
- Technical advantages: concentrated production capacity of high-end functional fabrics (flame retardant, chemical protection), rich foreign trade experience, and complete European and American certifications
2.Southern Manufacturing Center: Zhejiang/Jiangsu
Zhejiang (Yiwu, Shaoxing):
- Supply chain advantages: global base for disposable non-woven protective clothing, flexible small batch orders
Jiangsu (Nantong, Suzhou):
- Innovation highland: technological protective clothing (such as cooling workwear, smart wearable integrated workwear)
Procurement strategy:
- Budget-sensitive orders → Prioritize Hebei/Shandong manufacturers
- High protection level requirements (EN11611 flame retardant, EN20471 high visibility) → Focus on Shandong/Jiangsu
Ⅱ. Golden Rules for Wholesale Purchasing (6 Key Steps)
Step 1: Clarify technical parameters and filter out invalid suppliers
| Type | RII-Required Inspection Item | Avoiding pitfalls reminder |
|---|---|---|
| Basic requirements | - Fabric composition (cotton to polyester ratio) - grammage（g/㎡） - Reflective strip grade（EN ISO 20471） |
Hebei small factory often falsely labels weight and requires SGS fabric testing |
| Functional authentication | - Flame retardant standard（EN11611/NFPA2112） - Anti static electricity（EN1149） - Prevent liquid infiltration（EN13034） |
Verify the authenticity of the certification number and be alert to the PS certificate |
| Production standards | - Sewing process (double/triple line reinforcement)） - Quality of accessories (zipper/Velcro brand) |
Request to take actual photos of the details of the car seam |
Step 2: 4 channels for accurate screening of suppliers
1.B2B Platform Advanced Search
Alibaba keywords:
“wholesale workwear manufacturer china” + “MOQ 500”
“EN11611 coveralls factory” + “BSCI audit”
- Filtering tips: Check “Gold Supplier” + “Trade Assurance” + check “Production Certificates” column
2.Industrial Belt On-site Factory Inspection List (Hebei Key Areas)
- Shijiazhuang Industrial Park: Luancheng Equipment Manufacturing Industrial Park, Zhengding Labor Protection Products Base
- Items that must be checked during factory inspection: automation level of cutting workshop, needle detection equipment, chemical storage compliance
Step 3: Three levers for cost control
- Fabric alternative: Traditional pure cotton → blended (65% polyester + 35% cotton): cost ↓15%, wear resistance ↑
- Logistics optimization: Hebei shipment → Tianjin Port LCL: Ocean freight is 8-10% lower than Qingdao Port
- Tiered pricing strategy:
| Order volume | Unit price reduction | Payment Terms |
|---|---|---|
| ＞5,000 items | 12-15% | 30% deposit + 70% upon bill of lading |
| ＞10,000 items | 18-22% | LC 60天付款 |
Ⅲ. In-depth factory inspection checklist (key items for Hebei suppliers)
✅ Qualification documents:
- Safety production license (Hebei)
- BSCI/RCS social responsibility report (required for export)
✅ Production line key points:
- Special sewing thread for flame retardant clothing (aramid thread VS ordinary thread)
- High-visibility clothing reflective material inventory (3M certification code verification)
✅ Testing capabilities:
- Own laboratory → Require video demonstration of vertical burning test
- Third-party report → Confirm that the testing agency is a CNAS accredited laboratory

V. Risk Warning and Response Strategies
⚠️ Risks specific to Hebei:
Small workshop outsourcing trap: requiring real-time video of the workshop (with date watermark)
Environmental protection production restriction season (November to February of the following year): the contract needs to include a “force majeure extension clause”
🛡️ Quality Insurance Program:
It is recommended to purchase Sinosure quality insurance, covering indicators:
Insufficient color fastness
Suture breaking force is unqualified
Reflective material failure
Action Roadmap:
Why is Haiyuan worthy of priority assessment?
In the Hebei labor protection industry belt, its dual model of “localized supply chain + export-level quality control” provides buyers with an unrepeatable cost-effective combination, which is particularly suitable for engineering contracting, mining groups and other companies that require large-scale installation.
