Blanket Order & VMI Program
Scheduled production runs from 178+ Dolphin-audited Vietnam factories. Fixed pricing. Buffer stock. FTA documentation on every release.
Move beyond one-off orders. Dewin's Blanket Order & VMI program builds a managed, long-term supply relationship between your company and the right Vietnam factory — with 50-point quality assurance and full FTA paperwork on every shipment.
What Is a Blanket Order Program?
Long-term production relationships with Vietnam factories — with fixed pricing, scheduled releases, and Dewin managing every quality and documentation step.
Blanket Purchase Order
You commit to a total annual quantity. The factory reserves capacity and pre-sources raw materials. Individual shipments are "called off" on a schedule — monthly, biweekly, or on demand.
Vendor Managed Inventory (VMI)
Dewin holds 4–8 weeks of finished goods at the factory. When your stock drops below the reorder point, we automatically trigger the next production run and release. No stockouts.
Dolphin Audit Quality Guarantee
Every factory on the program scores Tier 1 (90+) or Tier 2 (80+) on the 50-point Dolphin Audit. Pre-shipment inspection is conducted on every release before goods leave Vietnam.
50-Point Dolphin Audit: The Quality Foundation
Every factory on the Blanket Order program has been physically audited against all 5 pillars. Long-term programs demand verified factories — not just marketing brochures.
Pillar 1 — Facility & Safety
10 ptsProduction floor condition, material storage, fire safety, and environmental compliance — predictors of production stability.
Pillar 2 — Equipment & Capacity
10 ptsMachine models, maintenance records, capacity utilization, and equipment age — determines ability to fulfill blanket volume commitments.
Pillar 3 — Quality Systems
10 ptsISO certification (physical verification), NCR system, calibration records, inspection equipment (CMM, VMM, hardness tester).
Pillar 4 — Workforce & Management
10 ptsWorker stability, management responsiveness, English capability, technical competence, and production planning maturity.
Pillar 5 — Export Compliance
10 ptsVCCI registration, Form B issuance capability, COO documentation records, raw material origin traceability, anti-circumvention compliance.
FTA Documentation on Every Release
Every shipment release under a Dewin Blanket Order includes the correct CO documentation for your target market — qualifying your parts for FTA import duty savings.
FTA rates and eligibility depend on specific HTS codes and rules of origin. Dewin verifies CO eligibility per shipment. Learn more about COO documentation →
How the Blanket Order Program Works
From first drawing to ongoing automated replenishment — managed end-to-end by Dewin's on-ground Vietnam team.
Part Qualification & Factory Match
Week 1–2Submit drawings and annual volumes. Dewin matches to the right Dolphin-audited factory from our 178+ network based on capability, certification, capacity, and QCLDM tier.
Blanket Quote & Agreement
Week 2–3Factory issues a fixed-price blanket quote. Dewin reviews and structures the agreement — unit price, MOQ per release, total annual commitment, price guarantee period, and tooling terms.
First Article Inspection (FAI)
Week 3–10 (process-dependent)Factory produces first article parts. Dewin conducts on-site dimensional inspection and physical audit. You approve FAI. Tooling registered to your account with ownership documentation.
Buffer Stock Production
Week 10–14First production run builds your agreed 4–8 week buffer. Pre-shipment inspection conducted. Buffer stock held at factory, photographed, documented, and ready to release.
Scheduled Release Cadence
OngoingYou call off releases against the blanket — monthly, biweekly, or on-demand. Each release ships with PSI certificate, VCCI Form B COO, material certs, and dimensional report.
VMI Auto-Replenishment
Ongoing (automated)Dewin monitors buffer inventory. When stock drops below reorder point, next production run is automatically triggered. Periodic factory re-audits ensure sustained quality standards.

Why Source Through Dewin vs Direct?
Going direct to a Vietnam factory can work — but managing quality, documentation, and long-term supply risk without an on-ground partner is genuinely hard.
