The minimum order quantity (MOQ) for silicon carbide (SiC) components at ZIRSEC starts at just 10 pieces for most standard parts and as low as 5 pieces for certain custom parts, allowing you to prototype or run small production runs without a large upfront investment.
Why MOQ Matters for Your SiC Project
Engineers and procurement managers often face three core concerns when sourcing SiC parts:
- Cost control: High‑temperature, wear‑resistant SiC parts are premium materials; a lower MOQ reduces capital tied up in inventory.
- Design validation: Many high‑temperature processes require several design iterations before final approval.
- Supply reliability: Production delays can halt an entire plant. A supplier that can deliver small batches quickly mitigates that risk.
Our experience with European pump‑valve makers shows that an 8‑day supply interruption caused by an unavailable SiC seal ring can cost $15,000 in lost production. By offering a 10‑piece MOQ, we keep a buffer stock that eliminates such downtime.
Quick Summary – FAQ
What is the absolute lowest MOQ you accept?
For standard‑size SiC tubes, plates, and rings the MOQ is 10 pcs. For custom geometries the MOQ can be 5 pcs if the design is simple (e.g., straight tube, basic ring). Complex shapes (multi‑axis machining, internal channels) start at 20 pcs.
How does MOQ affect price?
Unit price drops roughly 8‑12 % when you move from 10 pcs to 100 pcs. For orders above 500 pcs we apply a tiered discount that can reach 20 % off the list price.
What is the typical lead time for a 10‑piece order?
Standard parts: 2‑4 weeks (including quality inspection). Custom parts: 4‑6 weeks for 5‑10 pcs, depending on the machining complexity.
Can I combine different SiC items in one MOQ?
Yes. We treat the total piece count across a single engineering drawing set as the MOQ. For example, 5 tube blanks + 5 seal rings meet the 10‑piece threshold.
Do you provide engineering support for low‑MOQ orders?
Our in‑house engineers work with you on CAD review, tolerancing, and material selection at no extra charge for orders up to 50 pcs.
Standard SiC Components and Their MOQs
Our catalog contains dozens of off‑the‑shelf SiC parts that are kept in inventory. Because they are stocked, we can ship them within 24 hours once the order is confirmed.
| Component | Typical MOQ | Lead Time |
|---|---|---|
| SiC Ceramic Tube (Ø10‑50 mm, 500‑2000 mm length) | 10 pcs | 2–3 weeks |
| SiC Seal Ring (ID/OD 5‑30 mm) | 10 pcs | 2–4 weeks |
| SiC Plate (100 mm × 100 mm × 10 mm) | 10 pcs | 3 weeks |
| SiC Burner Nozzle | 10 pcs | 3–4 weeks |
| Custom SiC Roller (diameter ≤ 100 mm) | 20 pcs | 4–6 weeks |

Custom SiC Parts – How Low Can the MOQ Go?
When the geometry falls outside our stocked range, we shift to a made‑to‑order workflow. The factors that determine the MOQ are:
- Tooling complexity: Simple boring or turning operations require minimal setup, allowing a 5‑piece MOQ.
- Material waste: If the raw billet utilization is above 70 %, we can accept smaller batches.
- Inspection regime: For high‑risk applications (e.g., aerospace‑grade furnace tubes) we run full‑width X‑ray and ultrasonic checks, which adds cost but does not increase MOQ.
One of our German customers needed a batch of 12 custom SiC crucibles with an internal channel for molten silicon. We produced a 5‑piece pilot run, performed a high‑temperature cyclic test, and then scaled to 50 pcs within two weeks of approval. The total project cost was 15 % lower than the competitor’s quote because we avoided a high‑volume minimum.
Pricing Structure Tied to MOQ
Our pricing model is transparent:
- Base price covers raw material (SiC ≥ 98 % purity), standard machining, and a single 100 % inspection.
- Each additional piece beyond the MOQ reduces the unit cost by a fixed discount tier (see the table below).
- For orders under 10 pcs we still honor the base price but apply a 5 % surcharge to cover set‑up.
| Quantity Range | Unit Price Discount |
|---|---|
| 5–9 pcs | 0 % (base price) +5 % set‑up surcharge |
| 10–49 pcs | 0 % |
| 50–199 pcs | 8 % off |
| 200–499 pcs | 12 % off |
| 500 pcs & above | 20 % off |
All quotes include a COA (Certificate of Analysis) and MSDS, which are required for customs clearance in the US and EU.
How We Manage Lead Times for Low‑MOQ Orders
Speed is a competitive advantage in the SiC market. Our production line runs two shifts, and we keep a sandbox of raw SiC billets ready for rapid machining. The typical workflow is:
- Order Confirmation (Day 0‑1): Our sales engineer verifies drawing, tolerance, and material grade.
- Tooling Check (Day 1‑2): For simple cuts we reuse existing tools; for complex parts we fabricate a new CNC program.
- Machining (Day 3‑10): Batch size determines batch‑run length; a 10‑piece order can finish within a week.
- Inspection & Packing (Day 11‑14): Dimensional check (±0.2 mm standard), surface roughness, and visual defect screening.
- Logistics (Day 15‑21): Freight forwarder picks up the order; we provide all export documents.
For emergency orders we can expedite machining to 48 hours and ship via air cargo, adding a 20 % surcharge.
Risk Mitigation – What Happens If MOQ Is Too Low?
In a few niche cases a very low MOQ can expose both buyer and supplier to risks:
- Material batch variance: SiC powder batches can vary in grain size. We mitigate by storing multiple verified batches and performing a micro‑structure scan on every lot.
- Tool wear: High‑precision cuts on small batches still cause tool wear. We schedule preventive tool replacement after every 50 cuts to keep tolerances within ±0.2 mm.
- Shipping cost per unit: Very small orders (<5 pcs) are discouraged because air freight becomes uneconomical.
Our policy is to guide the customer toward a MOQ that balances cost and reliability. In practice, most of our B2B clients settle on 10‑15 pcs for the first run.
Case Studies Highlighting Low‑MOQ Success
Case 1 – US Solar‑Thermal Plant
The client needed 12 SiC tubes (Ø25 mm × 1500 mm) for a new solar‑thermal receiver. With a 10‑piece MOQ we supplied 12 pieces, performed a 1200 °C thermal shock test, and the plant achieved a 25 % efficiency gain. The project stayed within budget because we avoided a 200‑piece minimum that would have left excess inventory.
Case 2 – German Pump‑Valve Manufacturer
A pump maker required 15 custom SiC seal rings (ID 8 mm, OD 15 mm) for a high‑pressure pump upgrade. Our 10‑piece MOQ allowed a rapid 2‑week delivery. During the first month of operation, the pump ran 30 % longer between maintenance cycles, delivering a clear ROI.
Case 3 – UK Research Laboratory
The lab ordered 5 SiC crucibles for a high‑temperature alloy experiment. Although the MOQ for crucibles is 10 pcs, we made an exception after a technical review and delivered the 5 pieces within 3 weeks. The experiment succeeded, and the lab placed a follow‑up order of 50 pcs for a larger study.
