Auditing a Dice Factory: What to Check Before You Order

A deposit on a custom dice run is an act of faith. You wire half the invoice to a workshop an ocean away, on the strength of a storefront, a sales chat and a folder of glamour shots. Most horror stories in this industry — vanished deposits, sets that arrive dull, tolerances that drift mid-run — trace back to a single moment: the buyer never actually checked who they were buying from. This is our factory's honest answer to the question we wish more buyers asked us: how do you audit a dice factory before you order?

1. Start with the paper trail, not the product photos

Product photos prove nothing; anyone can download them. Registration documents are harder to fake and much more revealing. Ask for the supplier's registered legal name and business licence, then cross-check that the name on the licence matches the name on the proforma invoice you'll eventually pay. A mismatch between "the brand", "the company" and "the beneficiary account" is the classic signature of a trading company relaying your order to a workshop you'll never meet.

Take us as a worked example of what a clean paper trail looks like. YSDICE is the B2B face of Dongguan Yushun Hardware Co., Ltd. (), and we've been casting dice in Chang'an, Dongguan since 2018. That's a verifiable legal entity, a named district, and a founding year you can check against the record — our Alibaba storefront shows nine years focused on polyhedral dice, with a 4.9/5 rating across 459 reviews. You are not looking for a beautiful answer; you are looking for a consistent one. When the licence, the storefront, the invoice header and the shipping origin all agree, the story is probably true.

Also ask the simplest question in sourcing: where exactly is the factory? A genuine manufacturer names the city, the district and usually the street without hesitation, and will invite you to visit. A middleman gets vague, or names a city that doesn't match the licence.

2. Walk the floor — even from your desk

Nothing replaces standing on the casting floor, but a live video call gets you 80% of the way there for the cost of a calendar slot. Ask your contact to walk the phone through the workshop while you watch: die-casting machines cycling, resin pouring stations, sanding benches, the QC table. You're checking three things — that the floor exists, that it's currently running, and that the equipment matches the product range you were promised.

If your order is large enough to justify it, commission a third-party inspection firm to visit in person. Any factory confident in its floor will say yes immediately — we welcome third-party audits, and the factories worth your deposit generally do. The suppliers who suddenly discover "scheduling problems" when an independent inspector is proposed are telling you everything you need to know.

3. The six-line test: match the catalogue to the machines

Here is a pattern worth internalising: a trading company can sell you anything, instantly. A real factory can make certain things very well and is honest about the rest. So probe the catalogue. Ask which product lines run in-house, on what equipment, and which steps involve outside partners.

On our floor that answer is specific: six lines in-house — die-cast zinc-alloy metal on three casting machines, sharp-edge epoxy resin that is hand-poured and hand-sanded through five grits, rounded resin and liquid core, injection acrylic, plus silicone, wood and hand-carved gemstone — alongside accessories like wooden and magnetic dice boxes, PU leather bags and hexagon trays. And one step deliberately is not in-house: electroplating, which runs through two dedicated plating partners so every metal set is plated fresh to order rather than pulled from a shelf. That kind of unprompted honesty about what's outsourced, and why, is a green flag. A supplier who claims to do everything under one roof, including specialist surface chemistry, is usually describing someone else's roof.

4. QC you can verify: Inspection, SGS and toy safety

Every supplier says "strict quality control". Your job is to convert that slogan into documents. Three requests will do it.

First, ask what sampling standard governs the pre-shipment inspection. The professional answer is a named AQL level — ours is a two-stage inspection — once at the workshop that made them, once again before dispatch — with a photo report, which means a statistically defined sample of your run is pulled and inspected against agreed defect limits before anything ships, and you see the evidence. A supplier who cannot name an AQL level has no inspection system, only good intentions.

Second, ask for material certificates. SGS material reports tell you the zinc alloy or resin is what the quote said it was. Third, if your dice could end up in younger hands or in retail, ask about EN71 and ASTM toy-safety testing — retailers and fulfilment partners increasingly demand it, and a factory that already tests to those standards saves you a compliance scramble later.

5. Sampling is the cheapest audit you will ever run

A sample is not just a preview of your product — it is a stress test of the whole operation. It tests communication (did they understand the spec?), engineering (can they hit it?), and logistics (did it arrive when promised?). We turn custom samples around in 3–5 days, stock-design samples within a week, and refund the sample cost on your first order; whatever factory you audit, get their equivalent numbers in writing and hold them to the dates.

When the sample lands, inspect it like an engineer, not a fan. Check face flatness against a desk edge, numeral paint fill under magnification, edge and corner symmetry, plating coverage inside recesses, and — for resin — clarity and bubble control. Then float-test or spin-test for balance. While you're at it, confirm the production timeline behind the sample: a steel mold takes 20–25 days to cut, and mass production runs 10–30 days depending on material (metal 20–25, sharp edge 15–20, rounded 25–30, acrylic 20–25). A supplier promising a full custom metal run in two weeks is either cutting corners or quoting a fantasy.

6. Measure the track record, not the promises

Promises are free; operational metrics are earned. Three numbers tell you more than any brochure. Response time first: our average is under seven hours, and in general a supplier who is slow while courting your deposit will be glacial once they hold it. On-time dispatch second: ours runs at 99% or better, and you should ask any factory how they measure theirs — a supplier who has never measured it doesn't manage it.

The number I'd trust most is the reorder rate. Reviews can be curated, photos can be borrowed — but nobody reorders from a factory that burned them.— Queenie, YSDICE project manager

That third metric — repeat business — is the closest thing sourcing has to ground truth. A 26% reorder rate means a quarter of the buyers who have been through the whole cycle, from quote to unboxing, chose to come back. Whatever supplier you're vetting, ask what share of their revenue is returning clients, and watch whether the answer is a number or a shrug.

7. Commercial terms that protect you

The last audit layer is the paperwork you'll actually sign. Industry-standard payment is a 50% deposit with the balance before shipment — treat any demand for 100% upfront from a new supplier as a red flag. Prefer payment rails with recourse: Alibaba Trade Assurance holds funds against the agreed spec and date, and T/T or PayPal leave a clean trail. Confirm your trade-term options — EXW, FOB or DDP — and make sure the quote states which one, because a "cheap" EXW price can swallow its savings in freight handling you didn't budget.

Two clauses matter more than buyers expect. Get mold ownership in writing: who paid for the steel, who keeps it, and whether the tooling cost is refunded as reorder volume accumulates (ours is). And confirm your designs are protected — we sign NDAs on request and never resell a client's molds or designs, and molds are archived so a reorder colour-matches a year later. A factory that hesitates on either clause is planning a future you won't like.

8. Quote forensics: reading an offer like an auditor

The quotation itself is an audit document, if you read it the way we write it. A factory that runs a disciplined floor produces a disciplined quote, because the numbers come out of a costing system rather than a negotiating posture. Look for five things in the offer before you compare a single price. The mold fee should be stated as a one-time figure — in this industry, $600–$2,000 by complexity — with the refund mechanics in writing if reorder volume earns it back. The sample policy should carry dates and a cost treatment; ours reads "custom in 3–5 days, stock within a week, refunded on the first order", and whatever factory you audit should hand you something equally checkable. The trade term should be named — EXW, FOB or DDP — not implied. The production window should differ by material, because the processes differ: a quote listing one flat "15 days" for metal, resin and acrylic alike was written by someone who has never actually scheduled those three lines. And the inspection standard should appear on the proforma itself, so that our two-stage inspection becomes a contractual promise instead of a slogan on a website.

Now the red flags. A suspiciously round total with no breakdown usually means the seller is quoting from a reseller margin, not a bill of materials. "Free mold" is the loudest one: hardened steel and 20–25 days of machining are never free — the cost is buried in the unit price, which quietly converts your tooling into their leverage, because a mold you never paid for is a mold you will struggle to claim when you want to move or reorder. And the unit price dramatically below the pack is the most expensive number on the page. A fair price for a hand-sanded sharp-edge set has patient labour inside it; a quote that deletes that labour has deleted the five grits along with it. Cheap is a process claim. Audit it like one.

9. The ten-day audit calendar you can copy

Sequenced properly, the whole method fits inside ten working days — and most of it runs in parallel with getting your design quoted anyway, so the audit costs you almost no calendar at all.

Two practical notes from watching hundreds of buyers run versions of this. First, audit two suppliers in the same ten days, not one — the comparison exposes evasions that a single conversation hides, because you now know what a direct answer sounds like. Second, keep every answer in writing in one thread. The audit's real product is a paper trail you can hold a factory to at week six of production, and a WhatsApp voice note is not a paper trail. When buyers run this play on us, the whole exchange typically closes inside the ten days — the documents exist, so producing them is an attachment, not a project.

10. Auditing for year two: capacity, records and the claim that lands

Everything so far audits the first order. If your project works, the relationship you are really buying is the second year — and it has its own checklist. Ask how molds and colour records are kept: the steel should be archived with the approved specification and the Pantone recipes on file, so a reorder placed twelve months later matches the first batch without a fresh sampling loop. Ask about peak-season capacity: the fourth quarter is crowded with crowdfunding fulfilment, and a factory should be able to tell you how far ahead a Q4 slot books and what happens to your timeline when the floor is full. A vague answer in July becomes your delay in November.

Then ask the uncomfortable one: what happens when a defect lands anyway? No process yields zero defects — inspection catches defects, it does not abolish them — so the mature question is remediation. Get the claim procedure in writing before the deposit: what evidence is needed (photographs against the photo report you already hold), what the remedy is (replacement pieces in the next run, or credit), and how fast the answer comes. A factory's behaviour on a hundred-dollar claim predicts its behaviour on a ten-thousand-dollar one, and a supplier with a named procedure has handled claims like an adult before. This is also where a named project manager matters — a consistent contact who answered in under seven hours while courting you should still be answering at that speed in month eight, and at YSDICE that continuity is deliberate: the same file that Dongguan Yushun Hardware Co., Ltd. keeps for its own production management — mold registry, Pantone records, inspection reports — is the file your year-two questions are answered from. A factory that manages itself on paper can prove itself on paper. That, in the end, is what an audit is checking for.

The one-page audit, and when to walk away

None of this requires a flight to Guangdong. A licence check, a video floor walk, three documents, one sample and two written clauses — perhaps ten days of elapsed time — will separate a real factory from a storefront with confidence. Here is the whole method in one table.

And when a supplier fails two or more rows? Walk. The custom dice world is small, the good factories answer these questions gladly, and the ten days you spend auditing are cheaper than the six months you'd spend recovering a lost deposit — or relaunching a campaign whose dice arrived wrong.
