Which manufacturing route makes sense?
This is a decision checklist, not a market-average price or speed claim. Evaluate like-for-like product specifications.
Local Korean production may fit when…
- • A prototype is urgently needed
- • Frequent engineering changes are expected
- • On-site inspection must be immediate
Vietnam sourcing may fit when…
- • Repeat batches of stable drawings
- • Longer production planning horizon
- • Several manufacturers can quote the same specs
LANDED COST & LEAD-TIME MODEL
Compare total costs, not just unit prices
Adjust unit price, setup, QC, shipping, import charges and the stages of fulfillment. The calculator starts with fictional numbers for illustration only.

Scenario difference: Vietnam is 1,970,000₩ (19.6%) lower. Vietnam takes 16 days longer.
Demo assumptions, not published market rates or binding supplier quotations. Total = unit × quantity + setup + freight + QA + manually entered import costs. Lead time assumes RFQ, sample, production and delivery are sequential. VAT, currency fluctuations and unlisted charges excluded unless entered. Verify Incoterms, HS classification, tariffs and import obligations before ordering.
Cost analysis should use the same currency, Incoterms, inspection scope, delivery point, order volume and product specification. Import declaration and preferential duties require separate verification.
STEP-BY-STEP PROCUREMENT
Six steps from requirements to shipment
Stages are adapted for each order and are not a service-level guarantee.
- 01
Review RFQ / drawing scope
Define part, quantities, material, tolerances, finish, required standards and target delivery.
- 02
NDA & DFM discussion
Agree NDA for sensitive files and discuss design-for-manufacture requirements.
- 03
Screen machine shops
Review machinery, measurement capability, material options, capacity and export readiness.
- 04
Comparable quotations
Compare like-for-like unit rates, setup, MOQ, Incoterms and sample costs.
- 05
Prototype & first-article check
Validate dimensions, function and appearance against agreed acceptance criteria.
- 06
Production & delivery
Coordinate production issues, shipping documentation, delivery and possible reorders.

Frequently asked questions
What MOQs and tolerances can a CNC supplier offer?
They depend on the machine shop, process, material and drawing complexity. Confirm against a specific RFQ and inspection plan.
Is Vietnam always cheaper and faster?
No. Repeated batches may improve unit economics, while setup, international transport, customs, quality issues and rework can reverse the advantage. Urgent prototypes may favor domestic production.
How do you protect confidential engineering drawings?
We do not collect drawings in the public form. Sensitive documents require an agreed NDA, limited access and transfer method.
Who is responsible for manufacturing quality?
KVBiz supports screening and coordination. Quality warranty, inspection and non-conformity handling belong in the supplier–buyer contract.
