What machining in Vietnam actually costs, and where the saving goes

September 26, 2026

A machined part has four cost components, and only one of them is genuinely cheaper in Vietnam. Knowing which one tells you in about a minute whether your part is worth sourcing here, before anyone quotes anything.

The four components

Material. Aluminium, stainless and steel are globally traded and the price per kilogram is broadly similar wherever you buy. A local mill might shave a little, an imported grade costs more here than at home. Treat material as neutral.

Machine time. This is where the difference lives. The hourly rate covers the machine, the floor, the power and the operator, and it is materially lower here than in the US, Germany or Japan. The more hours your part needs, the more the difference matters.

Setup and programming. Also labour, so it also moves. Its effect on the unit price depends entirely on quantity, because it is divided across the batch.

Freight, duty and handling. These only go up. Everything you save on the first three has to survive this line.

Which parts win and which do not

Run this test on your own part:

Your part	Likely outcome
Long cycle time, several setups, moderate material cost	Clear saving. This is the case this route was built for
Simple, fast, made from expensive metal	Thin saving. The metal dominates and the metal does not get cheaper
Small, light, high quantity	Good. Freight per piece is low and machine hours are high
Large, heavy, low quantity	Usually not worth it. Freight eats the saving
Tight tolerance requiring a CMM at every stage	Possible, and the shop list is shorter, so the price gap narrows

The pattern: the saving comes from hours, not from parts. A part that takes twenty minutes of spindle time benefits. A part that takes ninety seconds does not.

The lines buyers forget

Freight is priced on volume, not weight, most of the time. A light part in a big box can cost more to ship than a dense one. Ask how the parts will be packed before you assume a number.

Payment friction. International transfers carry fees at both ends and a currency spread. On a 2,000 dollar order that is noise. On a 300 dollar order it is not.

Your own time. Sourcing, vetting, chasing and inspecting all cost money in salary, and that cost does not appear on any quote. It is the main reason buyers use a hub rather than qualifying a shop themselves.

Rework and scrap. A supplier that is 8 percent cheaper and produces one bad batch a year is not cheaper. This is why we measure parts before they are packed rather than after you open the box.

What we can and cannot control

We are transparent about the mechanics because it is the only way this decision gets made properly.

• We control: the choice of shop, so your part runs on a machine that suits it rather than one that happens to be free. The DFM review, which is usually worth more than any negotiation. The inspection, which stops a cheap part becoming an expensive one.
• We do not control: the metal price, the freight market or the duty rate in your country.

Our margin sits between what you pay and what the shop is paid, and there is no separate fee on top. That is the whole commercial model, stated plainly on the about page.

The changes that move a price the most

Before comparing suppliers, compare your drawing against itself:

1. Open the internal corner radii. A larger cutter runs faster through the same pocket.
2. Question the blanket tolerance. A general note with three called-out features costs far less than ±0.01 mm everywhere.
3. Quote two quantities. The gap between them tells you how much of the price is setup.
4. Use a stocked material. An imported grade adds weeks, and weeks are a cost even when they are not a line on the invoice.

Those four are worth more than any discount you will negotiate. The full list is in the DFM checklist, and the mechanics behind the price are in what drives the price of a machined part.

The honest summary

If your part is labour-heavy, made from a stocked material, small enough to ship economically and needed in a few hundred pieces, this route usually wins. If it is a heavy one-off or a fast simple part in an exotic alloy, it usually does not, and we will say so rather than quote it.

A worked comparison

Take the same part quoted two ways: an aluminium bracket, 180 x 90 x 40 mm, two setups, four toleranced bores, bead blast, 250 pieces.

Line	Western shop	Vietnam, through us
Material	Broadly the same	Broadly the same
Machine hours	The largest line	The same hours, a lower rate
Setup and programming	Spread over 250	Spread over 250, at a lower rate
Finishing	In house or local	Usually subcontracted, adds days
Inspection	Included	Included, and reported
Freight	Short, cheap	Long, and real
Duty	None	Depends on your country

The pattern holds on almost every part: two lines move in your favour, one moves against you, and the rest are flat. Which is why the answer depends on the ratio of machine hours to weight, rather than on a headline percentage.

Questions worth asking any supplier

1. What is the price at twice this quantity? It exposes how much of the unit price is setup.
2. Which single feature costs the most time? A supplier who can answer has read your drawing.
3. Is the material stocked or ordered? This is a schedule question that turns into a cost question.
4. What is the packed weight and volume? You cannot estimate freight without it, and freight is the line that decides the whole comparison.

Ask those four and you can compare any two suppliers in any two countries honestly, including us against someone closer to home.
