Sourcing Challenges (DIY)Dewin Dolphin Service®
icon Supplier Risk: Open B2B platforms with unverified factories and unreliable capacity claims. icon Verified Network: 7-year audited supplier network across China & Vietnam.
icon Quality Blindness: Quality decisions based solely on factory self-reports. icon Guaranteed Quality: Dolphin Reports, factory audits, and batch sampling inspections.
icon Tariff Exposure: Single-country sourcing with high duties and policy risk. icon Tax Optimization: CN/VN multi-country sourcing to reduce tariff impact.
icon Communication Gaps: Fragmented factory contacts causing technical misunderstandings. icon Project Control: Engineering-led coordination from drawings to mass production.
icon Hidden Costs: Manufacturing quotes exclude logistics, inspection, and export fees. icon Transparent Pricing: One all-in quotation covering production, QC, and delivery.
icon Delivery Uncertainty: No backup capacity when factories delay or overload. icon Stable Supply: Multi-factory backup capacity ensures consistent lead times.
icon No Accountability: Buyers take full responsibility when issues arise. icon Full Ownership: Dedicated teams manage production, customs, logistics, and quality.
