Inside Samsink Stainless Steel Sink Factory: MOQ, Tooling Cost, Lead Time and Full QC Process for OEM & ODM
If you are an importer, kitchen distributor, cabinet brand or commercial project buyer evaluating a stainless steel sink manufacturer, four questions decide your whole project: MOQ, tooling cost, production lead time and QC inspection. This guide answers all four with real numbers from the Samsink factory floor — covering our OEM & ODM workflow for handmade sinks, pressed sinks, workstation sinks and NSF certified commercial sinks. With decades of stainless steel sink manufacturing experience and dual production bases in China and Thailand, Samsink supports small-batch stock orders and fully customized private-label OEM & ODM sink projects for North America, Latin America, the Middle East and Southeast Asia markets. Direct answer: for existing standard sink models, MOQ is 20–50 pcs per SKU with no tooling charge. Semi-custom modifications start at 50–100 pcs. Fully custom sinks that require a new stamping mold start at 300–500 pcs per design. MOQ varies significantly depending on whether you select existing molds or develop new ones — this is the most common confusion for new buyers. 304 stainless steel · handmade & pressed sinks Fastest route to a differentiated SKU Your exclusive dimensions, layout and radius Direct answer: tooling cost is a one-time charge to develop stamping molds, bending jigs and welding fixtures for your exclusive sink design. After mold completion, all repeat bulk orders pay only the product unit price. We send you an exact quotation after reviewing your drawing — and long-term partners can get part or all of the tooling cost refunded. Direct answer: standard samples ship in 3–7 working days, standard bulk orders finish in 15–25 working days, and new-mold custom projects take 30–45 days for tooling plus 25–40 working days of production after sample sign-off. Peak season may extend lead time by 5–10 days — we always inform you in advance. Shipping time is separate from production. We support FOB, CIF, EXW and DDP terms from both China and Thailand ports for fast delivery to the US, Canada and other target markets. Direct answer: we run a 5-stage QC system, not just a final random inspection — from raw material certificates to 100% leak testing and pre-shipment salt spray sampling. Every welded sink passes a water leak test before it leaves the line. Our factory passes NSF audit and social compliance audit for commercial kitchen sink projects — see our NSF certified commercial sinks for restaurant and hospitality programs. Foshan (China) + Thailand plant for flexible production and tariff planning across markets. Farmhouse sinks, undermount, topmount, workstation, commercial sinks and mop sinks.

Most new partners start from our ready-mold catalog and add private label branding first. Two best-selling examples: For existing standard sink models, MOQ is 20–50 pcs. Custom sinks requiring a new mold normally start at 300–500 pcs MOQ. Tooling cost depends on sink structure and complexity. We send an exact quotation after reviewing your drawing, and long-term orders qualify for our tooling rebate program. Tooling takes 30–45 days, then bulk production runs 25–40 working days after sample sign-off. Standard ready sinks finish bulk orders within 15–25 days. Yes.
