We help overseas buyers source bolts, screws, nuts and washers from audited Chinese factories — with transparent pricing, factory visits, quality inspection, and consolidated shipments handled end-to-end.
Pick the model that fits your order — you can mix them within a single shipment.
You pay the factory directly. We charge a transparent 3–8% service fee on the FOB value. No hidden markups.
On-site visits, material verification via XRF spectrometer, pre-shipment inspection. Reports delivered as PDF + photos.
Monthly retainer + commission for Chinese factories that want a dedicated rep in Southeast Asia or the Middle East.
Mix multiple SKUs, sizes and finishes into one purchase order. We coordinate production across factories and ship as one LCL or FCL.
From off-the-shelf DIN parts to fully custom drawings. We work across five major standard systems and three material families.

You stay in control of every decision. We handle the friction between you and the factory.
Email or WhatsApp us a drawing, photo, or part number. We confirm feasibility and identify the right standard.
Within 48 hours we return 2–3 factory options with material, finish, MOQ and indicative pricing for each.
We arrange samples from the chosen factory. You approve appearance, dimensions and material before production.
Production follow-up, in-process checks, pre-shipment inspection. You pay the factory directly; we bill our fee separately.
Markets prioritized by anti-dumping tariffs, payment reliability, and repeat-order density.
EU and USA are case-by-case — most carbon and stainless fasteners from China face active anti-dumping duties. We help you check feasibility before quoting.
We started CMIOT because overseas buyers deserve the same factory access that large trading companies have — without the trading-company markup. Our name spells out exactly what we focus on: Custom parts, Metric standards, Industrial products, Overseas markets, Trade intermediation.
Hong Kong gives us a stable legal base, multi-currency banking, and a logistics hub with daily flights to every major region. China gives us the supply density — every fastener cluster we need is a 2-hour flight away.
We work with a deliberately small set of buyers at a time. Each engagement starts with a short call so we understand your specification, your end-customer, and what "quality" means for your market.
