I. Market Rates for Sample Fees
General market rates for sample fees. According to industry quotes, fees are tiered by type: samples of standard off-the-shelf parts cost approximately $10–$50 (tens to hundreds of RMB), or 1–3 times the mass-production unit price;
customized samples (involving color changes, marking, or minor modifications) cost $50–$200; and samples requiring new molds or complex tooling cost $200–$1,000 or more. In the automation component sector, typical costs are tens of RMB for standard parts, hundreds for custom machined parts, and thousands for molded plastic parts requiring new tooling.
II. Three Pricing Strategies
Three strategies for charging sample fees.
Industry practices include: charging a fee that is refunded upon placing a bulk order (the most common approach; it filters clients without appearing stingy, as the fee is deducted from the final order total);
charging the standard sample fee while the client pays for shipping upon delivery (common for high-value samples or custom equipment components); and providing the sample for free but charging for express shipping (suitable for low-cost standard parts, where the shipping cost itself acts as a filter—though fees should still be charged for high-value items like equipment, custom products, or parts requiring expensive molds).

Boundaries for Free Prototyping
Boundaries for free prototyping.
According to industry norms, “free” comes with conditions: standard catalog samples valued under $100 are usually free, though the recipient covers shipping for the first request; existing clients may receive samples for free, whereas new clients are typically charged. Minor modifications to standard parts (adjusting dimensions on existing specifications) are often free or incur only courier fees; once a partnership is established, initial shipping costs can be deducted from the first order total—meaning free prototyping is contingent upon securing subsequent orders.
IV.
Deduction and Refund Rules
Rules regarding deductions and refunds.
Industry practice generally allows sample fees to be offset: for custom-machined parts (MOQ of 1 unit), a reasonable prototyping fee is charged initially but fully refunded upon subsequent mass production; machine setup fees for springs are refunded after successful mass production or applied toward the final payment; for soft-tooling prototypes, if the subsequent formal mold order goes to the same supplier, the prototyping fee is offset against the mold cost at an agreed ratio (typically 30%–100%); standard part sample fees can usually be offset against the first order. Note that these offsets depend on securing a subsequent order;
this must be stipulated in the contract, as verbal promises are unreliable.
V. Prototyping Fee Expectations
Reasonable expectations for prototyping fees.
Based on industry experience, reference costs for automation component prototypes are as follows: standard off-the-shelf parts range from tens to hundreds of yuan (1–3 times the bulk price); custom machined parts (CNC, turning/milling) are calculated by man-hours (hundreds of yuan), with single custom prototypes costing around 800–1,000 yuan; plastic parts requiring mold creation cost hundreds to thousands of yuan for prototyping, with mold costs calculated separately (ranging from thousands to tens of thousands of USD); electronic components (including PCB firmware) incur higher prototyping costs. Before placing an order, clarify whether sample fees are deductible, as well as the deduction ratio and conditions, and ensure these details are noted in the order.
Conclusion
How much do sample parts for automation equipment cost? The answer is “tiered by type, with most costs being deductible.” Standard off-the-shelf samples range from tens to hundreds of yuan (1–3 times the bulk price); custom samples typically cost around 800–1,000 yuan; and parts requiring mold creation range from hundreds to thousands of yuan, with mold fees charged separately. Common pricing strategies include: refunding the fee upon order placement; charging the sample fee plus shipping (freight collect) for high-value items; and offering free samples for standard parts valued under $100 (with the buyer paying shipping). Regarding deduction rules: prototyping fees are fully refunded upon subsequent mass production; soft-tooling sample costs can offset 30%–100% of the final mold fee;
and standard part sample costs can offset the initial order total. Industry practice dictates that sample fees serve primarily as a threshold to filter for serious clients.
By clarifying three key points—the cost, deductibility, and specific conditions for deduction—and documenting them in a written agreement, you can transform the sample fee from a “trial-and-error” expense into a discount on your first order.
