Custom sheet metal parts from China are priced by material, part complexity, finish, and volume, plus any tooling or setup fees. Add international shipping and duties to reach true landed cost.
You order through one of three routes: direct to a factory, through a sourcing agent, or through a US-facing partner that runs production in China. Each route trades price against oversight.
At a glance
| Sourcing route | What drives your cost | Typical lead time | Best for |
| Direct to a factory | Lowest quoted per-part price; you absorb communication, QC, and freight coordination | Varies by shop; you manage the schedule | Buyers with in-house engineering and China logistics experience |
| Sourcing agent / broker | Factory price plus agent margin or fee | Adds a coordination layer on top of factory time | Buyers who want a single point of contact but not a full service partner |
| US-facing partner with China production | Bundled quote covering DFM, production, and often shipping | Prototyping in 3 to 7 days and production in 7 to 15 days is typical for some providers | Buyers who want engineering feedback and one contract, English-language support |
Lead times above are examples of what some providers publish; confirm current quotes for your specific part.
What actually drives the cost of a sheet metal part
The per-part quote is a stack, not a single number. Break it down before you compare vendors.
Material. Steel, stainless, aluminum, and copper alloys carry different base costs and machine differently. Gauge (thickness) matters too. Heavier stock costs more and can slow forming.
Part complexity. Bend count, tight tolerances, cutouts, and welded assemblies all add labor. A flat bracket with two bends is cheap. A multi-panel enclosure with welded seams and threaded inserts is not.
Finishing. Powder coating, anodizing, plating, and brushing each add a process step and cost. Some finishes also add days to the schedule.
Volume. Per-part price drops as quantity climbs because setup is amortized across more units. A run of 10 and a run of 1,000 have very different unit economics.
Tooling and setup fees. This is where buyers get surprised. Laser cutting and press-brake bending usually have modest setup charges. Stamping and deep-draw work need dedicated dies, and die tooling is a real upfront cost that only pays off at higher volumes. Ask any supplier to separate the one-time tooling fee from the recurring per-part price so you can see where your break-even sits.
Gavin Yi of Yijin Solution makes a point worth keeping in mind here: a low part price doesn’t always mean a low project cost. Hidden costs pile up through redesigns, repeated prototyping rounds, quality problems, and a rough production handoff. His view is to judge total project efficiency, not just the number on the quote. Treat that as one experienced opinion, then apply it to your own parts.
Shipping and landed cost
The quoted part price is not what the parts cost you. Landed cost is.
Sheet metal parts are often bulky and can be heavy, so freight matters. Small or urgent orders usually go by air, which is fast and expensive. Larger production runs go by sea, which is cheaper per unit but adds transit weeks. Add these to reach a real number:
- Factory-quoted part price and tooling
- Packaging (metal parts need protection against transit damage and corrosion)
- International freight (air or sea)
- Import duties and any tariffs on your product category
- Customs brokerage and inland delivery in the US
A part that looks cheap at the factory gate can lose its advantage once duties and air freight are added. Model the full landed cost for the quantity you actually plan to buy.
Going direct to a factory
Buying straight from a Chinese factory gives you the lowest quoted price. There’s no middle margin. The trade-off is that you own everything else: technical drawings in a format the shop can use, back-and-forth on manufacturability, quality inspection, and freight arrangement.
This route works if you have engineering staff who can read and correct a supplier’s questions, and someone comfortable coordinating international shipping. It works less well for a first-time buyer or a small team without those skills, because the problems that inflate total cost (misread tolerances, a rejected first article, a delayed shipment) land on you.
Working through a sourcing agent
An agent or broker sits between you and one or more factories. They handle supplier selection, communication, and often inspection and logistics, for a fee or a margin on the factory price.
Platforms like Hubs and Fictiv fit near this space with digital quoting and platform-managed sourcing, so you upload a file and get a quote back without hunting for individual shops. That’s useful when you want speed on the quoting side and a managed process rather than a raw factory relationship. The agent route in general suits buyers who want a single contact and someone to catch problems, without committing to a full manufacturing partner.
Watch the margin structure. Some agents quote you a bundled price and keep the factory quote private, which makes it hard to see what you’re paying for coordination versus parts.
Using a US-facing partner with China production
A US-facing manufacturing partner runs the factory relationship for you and gives you one contract, English-language support, and usually design-for-manufacturability feedback before anything gets cut. You get the cost base of China production with a smoother buyer experience. The quote often bundles engineering review, production, and sometimes shipping into one number.
This is the category Yijin Solution sits in. Sheet metal fabrication is one of its core services, offered alongside custom fasteners, and it has no minimum order, so runs can start at a single piece and scale to 100,000-plus parts, with sheet sizes up to 2440 × 1220 mm.
Prototyping typically runs 3 to 7 days; production batches typically take 7 to 15 days, though those ranges hold for many jobs rather than every one. You can see the scope of its work on the Yijin Solution sheet metal page.
An engineered, considered path is slower to start than pulling an off-the-shelf part or hitting an instant-quote button. Design feedback and validation take time before the first part ships.
If you need parts tomorrow and your design is already locked and simple, that upfront engineering step is time you may not want to spend. The payoff is fewer surprises later, which is where hidden project cost usually hides. For a well-defined, simple part in a hurry, a faster off-the-shelf or instant-quote route may serve you better.
How ordering typically works
The workflow is similar across routes, but a US-facing partner runs more of it for you.
- Send your design. Provide a CAD file, a 2D drawing with tolerances, material spec, finish, and quantity. The more complete this package, the tighter the quote.
- Get DFM feedback. A good partner reviews your design for manufacturability and flags anything that will raise cost or risk before production. Ask for this. It’s cheaper to change a drawing than a batch.
- Approve the quote. Confirm per-part price, any tooling or setup fee, lead time, and shipping terms in writing. Separate the one-time from the recurring costs.
- Prototype and validate. Order a sample or first article, check it against your drawing, and sign off before committing to volume.
- Run production and hand off. The supplier produces the batch, inspects it, packs for transit, and ships. Clarify who owns freight, duties, and inspection at this stage.
Frequently asked questions
How do I estimate landed cost before I commit?
Ask the supplier to itemize the part price, tooling or setup fee, and packaging, then add freight (air or sea), US import duties for your product category, and customs and inland delivery. Model it at the quantity you actually intend to buy, since per-part price and freight economics both shift with volume.
Are there tooling fees on every sheet metal order?
No. Laser cutting and press-brake bending usually carry modest setup charges rather than dedicated tooling. Stamping and deep-draw processes need custom dies, which are a real upfront cost that only pays back at higher volumes. Always ask a supplier to state tooling separately from per-part pricing.
Can I order a small quantity or a single prototype?
It depends on the supplier. Some Chinese partners set minimums; others don’t. Yijin Solution, for example, states no minimum order and takes runs from one piece up to 100,000-plus parts. Confirm minimums with any vendor before you build your cost model around a small batch.
Why can a cheaper quote end up costing more?
Because the factory-gate price is only one line in the landed total. Freight (especially air on an urgent order), import duties, and any tooling or die fees stack on top, and a part that looked cheap can lose its advantage once they’re added.
Then there’s rework: a rejected first article means another sample round and another shipment before you reach production. Price the full landed cost at your real quantity, not the per-part figure alone.
How long does production take?
It varies by part, finish, and volume, so get a written lead time with each quote. As a reference point, Yijin Solution publishes prototype turnaround of 3 to 7 days, with production runs at 7 to 15 days; treat those as typical, not a fixed commitment on any given job.
The short version
Pick your route by how much of the work you want to own. Direct-to-factory gives the lowest quoted price if you can manage engineering, QC, and freight yourself. An agent or a platform like Hubs or Fictiv adds a coordination layer and faster quoting.
A US-facing partner with China production bundles DFM, manufacturing, and support into one contract, trading a slower start against fewer surprises downstream. Whichever route you choose, price the full landed cost, separate tooling from per-part, and get lead times in writing.
