This is what a buyer checks before they shortlist a construction and building products supplier.
What does a buyer check before specifying tiles?
They check the technical classification and water absorption against the application, the slip resistance rating for the location, and batch and shade consistency. Slip resistance is a liability question in commercial projects, so it is checked before appearance.
A specifier is selecting tiles for a wet commercial area where a slip claim would be traced back to the specification.

What does a buyer check before specifying tiles?
What a buyer needs to identify the product
These are the fields a buyer scans before deciding whether you are worth contacting. Missing one of them usually ends the visit without an email.
- 1
Tile type and technical class
Porcelain, ceramic and natural stone perform very differently.
- 2
Water absorption class
Determines suitability for external and wet areas.
- 3
Slip resistance rating
A liability specification in commercial and wet areas.
- 4
Breaking strength and thickness
Governs suitability for floors and traffic levels.
- 5
Dimensions and rectification
Rectified edges change the joint width and the look.
- 6
Shade variation grade
Sets the buyer's expectation about batch appearance.
- 7
Frost resistance
Essential for external use in cold climates.
The documents buyers ask for
Not all of them belong on a public page. Naming the ones you can issue is what separates a supplier who can be audited from one who cannot.
| Document | What it proves | Where it belongs |
|---|---|---|
| Technical datasheetAsked at: specification | Classification, absorption, strength, slip rating and dimensions | Publish it |
| Slip resistance test reportAsked at: commercial and wet areas — a liability document | Rating under the method the market recognises | Publish it |
| Conformity certificationAsked at: specification and import | Conformity with the tile standard for the market | Publish it |
| Batch and shade informationAsked at: every delivery | Batch identification and shade grading for a delivery | Per shipment |
| Chemical and stain resistance dataAsked at: commercial and food areas | Resistance to cleaning agents and staining | Name it, share on request |
| Installation guidanceAsked at: installation | Adhesive, joint and substrate requirements | Publish it |
| Frost resistance test reportAsked at: external applications | Freeze-thaw performance for external use | Name it, share on request |
Where tiles and ceramics sites lose the enquiry
Each of these is common, cheap to fix, and costs an enquiry that never arrives — so nobody ever reports it.
Slip resistance not published
In commercial and wet areas it is a safety and liability specification. A tile without a rating cannot be specified into those spaces at all.
Water absorption class omitted
It determines whether the tile can be used externally or in wet areas. Buyers who overlook it produce failures blamed on the product.
No shade variation grading
Tiles vary between batches by design. Without a stated grade, normal variation becomes a dispute at installation.
What the enquiry form should ask
A form that collects these can be answered properly the first time. A form that collects a name and a message cannot.
Enquiry form — tiles and ceramics
Enough to reply usefully, short enough that a buyer finishes it.
- Application and location
- Floor, wall, internal, external and wet areas differ.
- Traffic level
- Domestic and heavy commercial need different classes.
- Slip resistance requirement
- Frequently set by regulation or insurance.
- Area and quantity
- Basis of price and batch planning.
- Size, finish and shade preference
- The visible selection.
- Project timing
- Batch reservation matters for large areas.
Questions suppliers ask
Why is slip resistance the first technical check in commercial work?
Because a slip injury is traced back to the specification, and the specifier carries the exposure. Publishing the rating and the test method for every tile makes your range usable in commercial projects; omitting it confines you to domestic work.
How should shade variation be handled?
By publishing the variation grade for each product and explaining what it means. Tiles genuinely vary between batches, and setting the expectation in advance converts a normal characteristic into an understood feature rather than a complaint at handover.
Should full technical data be public or supplied on request?
Public. Specifiers filter by absorption, slip and strength class, and a range whose data is behind a form is simply not considered. There is nothing confidential in classification data, and it is what makes the product findable.
Documents and standards named here are the ones buyers in this industry commonly ask for; requirements vary by market, customer and contract, so treat this as a starting checklist rather than a compliance list. Clearer pages can help discovery and evaluation. They do not guarantee rankings, AI citations, enquiries or revenue.
