Tariffs, lead times, and compliance headaches keep exposing how much electronics design still relies on China.
It’s not just a macroeconomic headline — it’s a design question:
Can you really get China out of your BOM?
And more importantly: what’s your plan if that dependency becomes too expensive, too slow, or politically restricted?
The Tariff Impact No One Budgeted For
As of March 24, a 10% U.S. tariff was placed on a wide range of Chinese electronics. And it’s not just about chips.
This round includes:
- Printed circuit boards (PCBs)
- Passive components like capacitors and resistors
- Rare earth elements such as neodymium and indium
You might be able to source high-end ICs from Taiwan or the U.S., but try finding reliable alternatives for low-margin, high-volume parts like SMD capacitors — especially if your existing design is tied to specific Chinese part numbers.
According to Accuris, a capacitor that cost $1 before may now cost $1.25. Multiply that by 10 components across 10,000 units, and you’re looking at thousands in unplanned costs. And that’s if you can get the parts at all.
“We’ll Just Source Elsewhere” — Really?
Many companies assume they can sidestep tariffs by moving production to Vietnam, India, or Mexico.
But here’s the issue: the parts themselves are still made in China.
Even if your product is assembled in Guadalajara, you’re likely importing:
- PCBs made in southern China
- Inductors wound with Chinese ferrite cores
- Displays built with Chinese indium tin oxide
Relocating production doesn’t solve upstream sourcing constraints. And building out new supplier relationships in non-tariffed countries can mean 8 to 10 week lead times, longer validation cycles, and incomplete logistics infrastructure.
Passive Components: The Silent Bottleneck
Passive components often fly under the radar. But they’re now the constraint that can derail a build.
From the Accuris parts database:
- Fixed resistors have relatively low risk — most can be sourced outside China.
- Fixed capacitors, on the other hand, are far more China-dependent. Alternatives exist, but they’re harder to validate and slower to ship.
This isn’t just about cost anymore. It’s about resilience — avoiding line-down situations over a part you forgot to double-source.
What You Can Do Now: A 3-Step BOM Risk Check
Before you go into production, run this quick audit:
- Flag China-only components
Check if any part in your BOM is sole-sourced from China. This includes passives, connectors, and rare earth–based subassemblies. - Identify viable alternates
For each high-risk part, determine if an equivalent is available from Taiwan, Japan, or elsewhere. Use tools like Accuris or simply ask your EMS to quote alternates. - Check your lead time assumptions
If moving suppliers, verify whether lead times go from 2 weeks to 8+ weeks. Don’t assume the alternate is a drop-in — check packaging, tolerances, and certification impacts.
You don’t need to redesign your whole product — but ignoring these steps can mean delay, cost overruns, or worse, a launch that never ships.
Titoma’s Strategy: Design for China-Resilient Electronics
At Titoma, we work with clients to design for geographic flexibility from the start. That includes:
- Avoiding sole-sourced Chinese components where possible
- Designing alternate footprints or drop-in equivalents
- Vetting suppliers in Taiwan, Southeast Asia, and Latin America
- Building full visibility into part origin and trade restrictions
See how this fits into our broader Design for Manufacturing (DFM) strategy.
Before You Finalize That BOM…
Ask your team:
- Are we tracking which components are made in China?
- If tariffs rise again, which parts will hit us the hardest?
- Do we have proven alternates outside of tariffed regions?
If the answers are unclear — or if your CM doesn’t give you full transparency — it’s time for a second opinion.
We can help you reduce risk without reinventing your design. Take a look at some of our recent electronics design projects.

FAQs
How do I estimate how much of my design depends on China?
Audit the full BOM and services. Tag each line with country for fabrication, assembly, and final shipping. Include PCB fab, enclosure, cables, batteries, packaging, test fixtures, and firmware tools. Sum spend share and identify single points of failure.
Does choosing non-China components remove China exposure?
No. Many distributors, sub-suppliers, plastics, cables, cells, and magnetics still originate in China. Even when ICs are fabbed elsewhere, lead frames, substrates, and packaging may involve China. Exposure usually remains unless you verify the full chain.
Which parts are hardest to move out of China?
Mechanicals and power parts. Enclosures, cable harnesses, batteries, magnets, speakers, and fasteners rely on dense clusters in China with short MOQs and fast tooling. Replicating that mix elsewhere raises cost and lead time.
How can I reduce dependency without a full redesign?
Design for portability. Add second sources for key ICs, keep footprints standard, avoid vendor-locked modules, specify alternate materials, and use neutral test jigs. Split the chain: PCBAs in Taiwan or Malaysia, plastics in Vietnam, final assembly near market.
What cost changes should I expect if I shift final assembly out of China?
Unit prices often rise 5–20%. You also add new NRE and a longer ramp. Some costs are offset by lower risk, steadier lead times, and reduced rework when process control improves.
Will moving assembly change the country of origin for tariffs?
Only if substantial transformation occurs outside China. Simple assembly may not change COO. Document process steps and get a binding customs ruling before you move, or you may pay tariffs anyway.
