A bad supplier rarely announces itself. The problems show up after the wire transfer clears — wrong wear layer, a batch that does not match the sample, certificates that do not check out. Most of it is avoidable if you know what to look at during vetting. Here are the signals that should make you slow down and ask harder questions.

Certificates that cannot be verified
Any serious SPC manufacturer can name the certification body and give you a document number you can check. If a supplier sends a blurry logo, a certificate with no registration number, or refuses to say who issued it, treat that as a stop sign. FloorScore, CE under EU 305/2011, and ISO 9001 all have verifiable references behind them — a real factory hands them over without drama. MILAT holds FloorScore, CE, and the full ISO family (9001, 10002, 14001, 27001, 45001), and shares documentation on request.
A trader dressed up as a factory
Plenty of "manufacturers" online are actually trading companies buying from whoever is cheapest that month. That is why batches drift and accountability disappears when something goes wrong. Ask for the factory address, the production line, and who owns the plant. MILAT manufactures in Gaziantep (Başpınar OSB) as the dedicated flooring manufacturer — you are dealing with the maker, not a middleman.
Vague or shifting specifications
A credible supplier states the wear layer, core type, click system, surface texture, and acoustic rating in writing. Watch for suppliers who quote a price before they will commit to specs, or who describe the product only in adjectives — "premium," "high quality," "strong." You want AC ratings, the click licence, the coating. MILAT SPC uses a licensed Unilin click, EIR surface, AC5 maximum wear, IXPE acoustic backing up to 21 dB, and 2X UV coating on a 100% waterproof core.
No samples, or samples that never match
If a supplier resists sending physical samples, ask why. Photos hide colour, gloss, and texture. And when you do order, the production run should match the sample and stay consistent batch to batch — a common failure point with low-tier factories. Always request samples and, for larger programmes, a reference of batch consistency.
Compare the promises
| Red flag | What a credible supplier does |
|---|---|
| "Trust us, it's certified" | Names the body and gives a checkable number |
| Price quoted before specs | Locks specs in writing, then prices |
| No factory address | Shares plant location and ownership |
| Only digital photos | Sends physical samples on request |
| Price far below market | Prices in line with real material and freight cost |
Prices that make no sense
SPC has a material floor — limestone core, virgin PVC, a real wear layer, UV coating, and freight all cost money. A quote dramatically under the market usually means a thinner wear layer than promised, recycled filler, or a spec swap on the production run. Cheap upfront becomes expensive on the claim.

Communication that fades
How a supplier communicates during sampling is how they will communicate during a problem. Slow replies, dodged technical questions, and no named contact are early warnings. You want one accountable point of contact who answers specifics.

The proforma invoice tells you plenty
Before any money moves, the proforma invoice is your preview of how the supplier works. A good one reads like a specification: product name and collection, dimensions, wear layer, total thickness, click system, packaging details, quantity by design, incoterm, port, payment terms and validity. A thin proforma with a product called something like SPC 5.5mm and a lump-sum price is a red flag in itself, because everything left vague is something that can quietly change between deposit and delivery. Insist that the document describes exactly what you sampled, and keep the approved sample itself labelled and stored; it is the physical standard every later argument gets settled against.
Refusing third-party inspection
Independent pre-shipment inspection is routine in flooring, and any established factory has hosted inspectors many times. A supplier who resists it, stalls the booking until the goods have shipped, or insists their own report is sufficient has told you where the risk sits. The refusal matters more than any excuse attached to it. A confident manufacturer treats inspection as free marketing: the inspector confirms what the factory already knows. Make inspection rights part of the order confirmation, not a favour requested afterwards.
Pressure tactics and expiring offers
Legitimate quotations do expire, because raw material and freight costs move. But pressure has a different smell: discounts that die tonight, a last container that three other buyers supposedly want, insistence on skipping the sample stage to catch a vessel. These tactics exist to shorten your due-diligence window, and that is their only purpose. A factory with real production has next month too. When urgency appears on the seller's side of the table before you have created any, slow down deliberately and watch how they react.
A useful counter-move is to state your process out loud: samples first, then documents, then a trial order, on your timeline. A genuine manufacturer accepts this without friction because it mirrors how their good customers already buy. A seller whose margin depends on you not looking closely will keep trying to compress the sequence, and each attempt is another data point you did not have to pay for.
Packaging tells the truth about a factory
You can read a factory's discipline from how a pallet arrives. Clean, printed boxes with design name, batch number, quantity and handling marks speak of a controlled operation. Generic brown boxes with a photocopied label, missing batch numbers, or pallets strapped as an afterthought predict the same carelessness inside the plank. Damaged corners and chipped click profiles from poor packing cause more site complaints than manufacturing defects do. Ask for photos of standard export packaging during vetting; the answer is evidence either way.
How claims are handled when something goes wrong
Every supplier is charming before the wire transfer; the difference shows when a problem lands. During vetting, ask directly: if a batch arrives with an issue, what is your claims process, what evidence do you need, and who decides? A serious manufacturer has a documented procedure, usually anchored in its quality certifications, and can describe a real past claim and its resolution. Evasive answers now predict evasive answers later, when the stakes are a container on your dock instead of a hypothetical. Write the agreed claims process into the order confirmation while goodwill is still cheap.
