FAQ
Answers before you send a drawing.
Straight answers on quoting, capability, tariffs and terms. Where the honest answer is "not yet" or "we are the wrong shop," that is what you will read below.
Before you quote
What is your minimum order quantity?
Minimum order quantity is set per part and process, and confirmed in the written quote. Our cost advantage comes from tooling amortized over production volume, so if your volume is too low for us to be competitive we will tell you rather than quote badly.
How fast do you turn around a quote?
Within 48 hours once we have a complete drawing package. STEP files and dimensioned PDFs move fastest; an incomplete drawing takes longer because we have to ask questions first.
What should I send for the fastest, most accurate quote?
A STEP file plus a dimensioned PDF is the fastest combination. Add your annual volume, material and finish, and any inspection or acceptance criteria, and we can usually quote without a back-and-forth.
Will you sign an NDA before reviewing my drawing?
Yes. Tell us you need one when you submit the RFQ or email us directly, and we will sign before we open the file. What an NDA does and does not protect with a Vietnam manufacturer is covered in NNN vs NDA.
Capability and quality
What tolerances do you hold?
Tolerances are confirmed feature by feature on the quote. On machined bores in castings we hold ±0.001 in. (0.025 mm), with GD&T concentricity to Ø0.003 in, and a surface finish to 125 RMS.
What materials do you run?
ADC12 aluminum and Zamak 3 zinc for die casting; brass and bronze for sand casting; steel grades 52100, C1117 and 12L14; aluminum 2011-T3 and 6061-T6; ASTM A513 DOM steel tube; and silicon bronze.
What finishes do you offer?
Electroplating, anodizing, gold plating, zinc plating, RoHS-compliant blue trivalent chromate, powder coating with pad printing, and oil-dip rust protection. We also cut ANPT and NPT threads to ANSI/ASME B1.20.1, and knurl.
Do you hold ISO 9001?
Not yet — certification is in progress, not held. What we can send today: a business registration certificate, an equipment and capacity list on request, first-article inspection reports, material certification on request, and salt-spray results. If a signed ISO 9001 certificate is a gate for your approved-vendor list, tell us before you send a drawing, not after samples ship.
What quality documents can you send today?
A business registration certificate, an equipment and capacity list on request, first-article inspection reports, material certification on request, salt-spray results, and RoHS declarations.
What work will you turn down?
Simultaneous five-axis work, single-micron tolerances, programs too small for tooling to amortize, and any program that requires a signed ISO 9001 certificate today. We would rather say no upfront than quote badly.
What is the difference between in-house and managed partner processes?
In-house means the machines and people of our lead CNC plant: CNC turning and CNC milling. Managed means we hold the drawing, the purchase order and the inspection, and a partner plant makes the part: die casting, stamping, surface finishing, sand casting (machined afterwards at our lead CNC plant), aluminum extrusion, injection molding, sheet metal and laser cutting, waterjet cutting, and rotational molding. Each quote names the production site and the country of origin.
Tariffs, origin and shipping
How does the Vietnam tariff compare to China's, as of September 2026?
As of September 2026, Vietnam's Section 301 rate is 12.5%. China's aggregate Section 301 rate is 37.5% on HTS lines covered by the legacy Lists 1–3. That gap is real, but it is Section 301 only — Section 232 metals duties and your specific HTS code still decide the actual landed cost. Sources: USTR's Section 301 notice in the Federal Register (July 28, 2026) and the US tariff schedule, chapter 99.
Does Section 232 apply to parts made in Vietnam too?
Yes. Section 232 metals duties apply regardless of country of origin, so a Vietnam-made part is not automatically exempt. Landed cost has to be worked out per part against its own HTS code, not assumed from the country alone.
Can you prove the parts are Vietnamese origin?
Yes, and we treat it as an engineering question, not a paperwork one. We keep a material traceability file per part number covering the process routing, the material source and the value added here, plus a Certificate of Origin Form B issued through Vietnam's Ministry of Industry and Trade. For your highest-exposure parts we will file for a binding ruling from US Customs.
What happens if a part is found to be transshipped, and what is the actual test?
If a part fails to qualify as Vietnamese origin, it is treated as Chinese origin: it pays the China tariff rates, and it is exposed to CBP enforcement action on top of that. The legal test is substantial transformation under 19 CFR 134.1(b) — the part has to genuinely change character here, not just pass through on its way to the US.
FOB or DDP — which should I choose, and who handles customs?
We quote FOB Ho Chi Minh City if you want to run your own import. If you would rather receive DDP, say so on your RFQ: whether DDP is available for your part, and who acts as importer of record, is confirmed per quote, in writing. FOB vs Delivered Duty Paid sets out who carries duty and customs liability under each, and the landed cost guide lists the fees on top of duty.
Commercial
How much does tooling cost, and who owns it?
Tooling cost is set per part and process and stated in the written quote, priced separately from the piece price. Tooling payment terms and tooling ownership are confirmed in the same quote. The terms to settle before the first shot are listed in who owns die casting tooling overseas.
How do you price, and how do we pay?
Quoted FOB Ho Chi Minh City; DDP terms and the importer-of-record arrangement are confirmed per quote. Tooling is priced separately from the piece price, and payment terms for tooling and production orders are set out in the written quote.
What happens if a lot fails inspection, or I need to change the design?
Tell us as soon as you find it — the right response depends on the part and the failure, so we will confirm the specifics on your quote and order. A design change moves a part back through first-article inspection before it runs in production again, so it stays qualified against the new print.
How is my part packaged and shipped?
Parts are individually bagged and packed in cartons under 30 lb. We quote FOB Ho Chi Minh City; DDP terms are confirmed per quote — see the FOB-or-DDP question above.
