Many buyers who have sourced CNC parts from mainland China are now looking at other suppliers in Asia. Taiwan is often the first place they check: it has a deep machining industry, an export-oriented supply chain, and a separate customs territory.
This guide lays out the practical differences so you can decide whether a Taiwanese supplier fits your parts.
Tariffs and country of origin
Taiwan is a separate customs territory, and goods made in Taiwan carry Taiwan as their country of origin. In the United States, the Section 301 tariffs on Chinese-origin goods do not apply to Taiwan-origin goods. Other US tariff measures can apply to Taiwan as well, and rates change, so always check the current duty for your part’s HS code before you compare quotes.
Country of origin is decided by where the part is substantially made, not where it ships from. A part machined in Taiwan from bar stock is a Taiwan-origin part.
Supply chain and industry depth
Central Taiwan, around Taichung, hosts a large cluster of machine tool builders, tooling suppliers, material stockists, heat treaters and finishing shops. For a machine shop this means short lead times on outside processes such as anodizing and heat treatment.
Taiwan’s machining industry grew up serving export customers in bicycles, automotive and motorcycle parts, machinery and electronics, so export packaging, documents and English-language drawings are routine.
Cost
For simple, high-volume parts, mainland China is often cheaper on unit price. For small and medium batches, parts with several critical features, or projects where engineering communication matters, the gap narrows. Compare landed cost — unit price, tooling, freight, duty and the cost of rejected parts — not unit price alone.
How to qualify a Taiwanese machine shop
Ask every supplier the same questions and compare the answers:
- Which machines they run and which part sizes and materials suit them
- What tolerance they routinely hold on your material
- Which processes they do in-house and which they send out (finishing, heat treatment)
- How they check critical dimensions before shipping
- Whether they can make a prototype or first batch before production
- Which countries they already ship to
Where Chi Xin fits
Chi Xin Technology is a CNC machine shop in Nantun District, Taichung, Taiwan, founded in 2022. We run 5+ CNC machines — 4.5-axis CNC machining centers and CNC lathes — and mainly machine aluminum alloys and alloy steel, with a metal tolerance of 0.02 mm. We also offer wire EDM and surface finishing including anodizing, and we export to customers in Europe and North America.
We machine aluminum and alloy steel parts — from prototypes to production runs — that need CNC turning, 4.5-axis milling, or both.
Frequently asked questions
Do Section 301 China tariffs apply to parts made in Taiwan?
Section 301 tariffs cover Chinese-origin goods. Taiwan-origin goods can be subject to other US tariff measures, and rates change, so check the current duty for your HS code with your customs broker.
Is Taiwan more expensive than China for CNC parts?
Unit prices are often higher on simple, high-volume parts. Compare landed cost — including duty, freight and quality costs — for your specific part.
Can I start with prototypes?
Yes. We machine prototypes as well as production runs.
