Six checks before you wire a deposit — and the red flags.
The short version: vet a wholesale drinkware supplier on six things before you commit — confirm they are a supplier that runs its own lines, get their certifications in hand, order a paid sample, check their MOQ is realistic, test their communication speed, and ask for references or case examples. A genuine factory welcomes every one of these; a reseller dodges them.
What you need to know is who will physically make your order and who answers when something goes wrong. Ask to see the line itself — photos, video, a live walkthrough — plus the address and the business licence. A supplier running its own moulding, welding, printing and packing can show you all four under one roof, and can change a spec mid-run without a week of emails. That access is the point; it is also perfectly normal to buy through a sourcing agent who has vetted that access for you.
For drinkware you need FDA 21 CFR, LFGB, EU 1935/2004 and California Prop 65 reports, plus GRS if you claim recycled content. A real supplier sends these on request. "We'll get it after the order" is a red flag.
Never skip the pre-production sample. Pay for it (cost is normally credited back against bulk), and check the colour match, logo, lid seal and overall finish. A sample tells you more than any catalogue.
A credible factory states a clear MOQ (around 500 pcs per design) and explains tooling and colour costs. Both extremes are warning signs: "no minimum, fully custom" usually means a trader, and a suspiciously huge minimum can mean they don't really want small buyers.
Send a detailed inquiry and time the reply. Good suppliers answer specific questions clearly and fast (we aim for within 24 hours). Vague, slow or copy-paste answers now become problems during production.
Ask how long they've operated, the brands or markets they serve, and for case examples. A 25-year factory that has supplied recognised brands is a very different risk profile from an unproven listing.
Shows the factory, sends certs fast, insists on a sample, clear MOQ, quick specific replies, real track record.
Won't show production, "certs later", skips samples, "no minimum fully custom", slow vague replies, no history.
We are the factory behind these articles — 500 pieces per design, samples in 7–10 days.
