Key Specifications and Standards
Industrial protective cases from KeXinMaterials comply with ISO9001:2015 quality management, ROHS, CE, REACH, IP67/IP68 ingress protection, MIL-STD-810G environmental testing, and ATA 300 Category I luggage standards. Selected SKUs include FDA compatibility statement for medical applications and NSN registration support for defense applications.
Standard SKU stock: 50-piece MOQ, 7-15 day delivery. OEM MOQ 100 pieces per SKU with 30-45 day production lead time. Custom tooling projects start at 500-1,000 pieces depending on complexity.
B2B Procurement Decision Framework
For B2B buyers, the procurement decision balances 5 factors: unit price, total cost of ownership (TCO), delivery lead time, certifications, and after-sales support. KeXinMaterials factory-direct pricing is typically 40-60% below Western brand retail for comparable specifications.
Recommended RFQ checklist: (1) target SKU or custom specifications; (2) annual volume forecast; (3) destination country and shipping terms (EXW / FOB); (4) required certifications; (5) customization needs (logo, color, foam, packaging); (6) sample policy; (7) warranty and spare parts; (8) payment terms (typically 30% deposit, 70% balance on B/L copy).
Production Capacity and Lead Times
KeXinMaterials operates a 13,000㎠ self-built facility with 60+ injection molding machines, rotomolding equipment, foam fabrication lines, and QC laboratories. Monthly capacity exceeds 50,000 cases across all product lines.
Standard SKU lead time: 7-15 days production + 18-35 days ocean freight (FOB Shenzhen to US West Coast 18-26 days, EU 24-32 days, US East Coast 28-35 days; FOB Ningbo adds 2-3 days). OEM 30-45 days production + same freight. Air freight 3-7 days available at higher cost.
Quality Control and Certifications
Every shipment includes an AQL 2.5 sampling inspection report. Quality control covers raw material verification (incoming PP/PA66/ABS), in-process checks (dimensions, weight, color match), pre-shipment audit (drop test 1.2m onto concrete, water immersion 30 min at 1m depth for IP67 SKUs, latch cycle test 50 cycles), and traceability records per batch.
Certifications held: ISO9001:2015, ROHS, CE, REACH, IP67/IP68, MIL-STD-810G Method 516.7 (drop) + Method 514.8 (vibration) + Method 501/502 (temperature), ATA 300 Category I, California Prop 65, FDA compatibility statement. Defect claims must be filed within 30 days of receipt with photos and batch number.
Total Cost of Ownership (5-Year)
Indicative 5-year landed cost per case for a 500-piece bulk order:
| Cost dimension | KeXinMaterials | Brand retail |
|---|---|---|
| Unit price (500 pcs) | USD 60-120 | USD 150-300 |
| Shipping (FOB/EU per case) | USD 4-8 | USD 6-12 |
| Warranty replacements (5 yr) | Free (1 yr + bulk 3 yr) | Free (lifetime, distributor-dependent) |
| Custom foam insert | USD 15-40 (in-house) | USD 30-60 (distributor margin) |
| Lead time loss (opportunity cost) | None / 7-15 day stock | Distributor-dependent |
Net savings: typically 40-60% vs Western brand retail for comparable specifications.
Customization and OEM Workflow
Step-by-step OEM process: (1) requirements submission (case type, target volume, custom needs); (2) DFM analysis + quote within 12 hours; (3) artwork approval (vector logo AI/EPS/SVG, 3D mockup within 24 hours, physical sample 7-10 days); (4) PO + sample fee (USD 200-1500, refundable against orders ≥ 1,000 pieces) + 30% production deposit; (5) custom production 30-45 days with AQL 2.5 QC; (6) shipment per agreed terms (EXW Shenzhen / FOB Shenzhen / FOB Ningbo) + 1-year warranty + free replacement parts.
Customization options: logo printing (silk-screen / pad / laser engraving), Pantone color matching (MOQ 300), custom foam interiors (EVA / EPE / PU), custom hardware (latches, hinges, handles, wheels), retail packaging (FNSKU labels, branded boxes).
