QB/T 2755 Explained: China's Carpet-Tile Standard (2005 → 2024) and How to Use It When Buying

1. What QB/T 2755 is — and the letters that matter

On a Chinese carpet-tile quotation you will often see a line like “complies with QB/T 2755”. It is worth knowing exactly what that claims, because the prefix carries as much information as the number.

QB/T 2755 is China's light-industry standard for carpet tiles. Broken into its parts: QB denotes the light-industry sector; the /T marks it as tuijian — recommended, meaning voluntary; and 2755 is the document number. It sets out how a carpet tile is classified, the requirements it should meet, the test methods used to check them, and the rules for inspection, marking, packaging, transport and storage.

The single most useful thing to understand is what the prefix is not: it is not a GB national standard, and it is not mandatory. That does not make it worthless — a voluntary industry standard is a perfectly good common baseline — but it means a QB/T 2755 claim is a statement about product quality conventions, not a statement about legal compliance or indoor-air safety. Those live elsewhere, as section 4 explains.

2. Where it sits in China's standards system

China's standards are tiered, and the prefix tells you both the tier and whether the standard is mandatory. The rule that repays learning once: a bare GB is mandatory; add /T and it becomes recommended. The same logic applies one tier down, which is why QB/T is a recommended industry standard.

3. The 2005 → 2024 change almost nobody flags

Here is the detail that is missing from every English page we could find on this subject, and the one most likely to catch a buyer out: the 2005 edition has been replaced.

QB/T 2755-2024 “Block carpet” was released on 10 December 2024 and took effect on 1 January 2026, superseding QB/T 2755-2005 “Carpet tiles”. The revision reorganises the requirements — broadly into internal quality and external quality — alongside the usual test methods, inspection rules, marking, packaging, transport and storage.

The practical consequence is simple. A supplier whose spec sheet or product page still cites QB/T 2755-2005 in 2026 is quoting a withdrawn edition. That is not necessarily a red flag on the product — it usually just means the documentation has not been refreshed — but it is a fair and revealing question to ask: which edition does your current test report cite, and can you send it? How promptly a supplier can answer tells you something about how they keep their paperwork.

We hold to the same test. Where we cite the standard, we cite the current 2024 edition, and if you are reading a document of ours that still says 2005, tell us — it means a page needs updating.

4. What the standard proves — and what it does not

Standards are deliberately narrow, and the narrowness is the useful part. A QB/T 2755 claim speaks to the physical product; it is silent on several things buyers often assume it covers.

That last row is the one to hold on to. If indoor-air quality matters to your project — and in an enclosed commercial interior it usually does — the document you want is GB 18587-2001, China's mandatory limit on harmful substances released from carpets, cushions and adhesives, or an internationally recognised emissions certificate. A QB/T 2755 line will not stand in for it. We cover reading an emissions certificate in detail in our Green Label Plus guide.

5. How it maps to the EN/ISO standards a Western spec uses

If you are specifying from Europe, the Middle East or Australia, your tender probably references EN or ISO standards rather than Chinese ones. QB/T 2755 does not map one-to-one onto them, so the cleanest approach is to treat each performance question as its own standard and ask for evidence against the one your project names.

A tidy specification pairs the Chinese product standard (QB/T 2755-2024) with the Chinese mandatory emissions standard (GB 18587) and cross-checks against whichever EN/ISO benchmarks the project references — then asks the supplier for a report against each named standard, not a single "meets all standards" line.

6. Where UNIJOY sits in this standard

We have a direct line to this document, and it is worth being precise about what that does and does not mean. UNIJOY's manufacturing predecessor, Shanghai Gaorong, was among the participating drafting units for QB/T 2755-2005, and Pei Hairong — our founder — was named as one of the principal drafters, on the standard's own preface list.

That is genuine background: it means the people who built our manufacturing operation were in the room when the industry wrote down how a carpet tile should be classified and tested. What it is not is a performance claim about any individual product. Helping draft a standard and meeting a project's emissions or fire requirement are separate things, evidenced separately — which is exactly the discipline this whole guide is arguing for.

7. Using a QB/T 2755 claim as a buyer

1. Read the prefix. QB/T = voluntary industry standard, not a mandatory national one. Calibrate the weight you give the claim accordingly.
2. Check the edition. The current edition is QB/T 2755-2024. A citation of the 2005 edition in 2026 is a withdrawn standard — ask for the current report.
3. Match the report to the tile. Confirm the tested sample's construction — yarn, pile, backing, format — matches the exact SKU on your quotation.
4. Ask for emissions separately. GB 18587 domestically, or Green Label Plus / an EPD internationally. QB/T 2755 does not cover it.
5. List fire, static and colourfastness as their own requirements, each with its own named standard and report.
6. Where a document doesn't match, ask rather than assume equivalence. A supplier who can hand you the right report for the right tile has answered the only question that matters.

The useful question is never “does the supplier mention a standard?” It is “can this supplier show which edition applies to this exact tile, and produce the separate evidence for everything the standard deliberately leaves out?” Answer that, and a compliance line stops being marketing and becomes something you can rely on.
