Certificate number LB2019QB003 is an Inclusion Certificate for the "Green Building Selected Product Guide Catalogue", issued by China Building Material Certification Group Co., Ltd. (CTC) to Nockybrothers new material (Wujiang) Co., Ltd. It covers seamless wall cloth products and is registered in connection with the company's Wall Covering product code 4341, alongside Grade 5 Waterproof Finished Art Paint (product code 4323). For a buyer in the evaluation stage, the document answers one precise question: is this art paint wall cloth listed under a named green building product framework, or is the environmental story only the supplier's own wording?

This guide is written for specifiers, importers, distributors, and procurement teams comparing art paint wall cloth suppliers. It explains who issued the certificate and under which framework, which product codes it covers, how to verify it step by step before ordering, where it carries the most weight in real projects, and which commercial variables sit alongside compliance in a purchase decision. It also states clearly what the certificate does not cover, because a compliance document is only useful when its boundaries are understood.

Problem Definition: Green Claims Are Easy to Make and Hard to Verify

The phrase "eco-friendly wall cloth" is a description, not a document. In art paint wall cloth procurement, three different categories of environmental evidence are routinely bundled into the same PDF pack and treated as though they carry equal weight:

• Material composition statements - what the wall cloth is made of, such as non-woven fabric, eco-friendly water-based resin, nano inorganic mineral fillers, high-quality shell powder, and a medical-grade base material.
• Management system certificates - how the factory designs and produces, for example an ISO 9001:2015 quality management system certificate covering the whole process of design and production of wallpapers and wall cloths.
• Product-level inclusion - whether a specific product has been assessed and listed under a named, third-party framework.

Only the third category is tied to a specific product code and can be checked against a published document name and number. It is also the category most often missing from a supplier pack, because it requires an assessment of the product itself rather than of the company's processes.

The practical risk for a buyer is therefore not usually counterfeit paperwork. It is category confusion: presenting a quality management certificate as if it were a product-level environmental approval, or applying a certificate issued for one market to a project located in another. Certificate LB2019QB003 sits firmly in the third category, and reading its scope correctly is the fastest way to place the material accurately in an evaluation matrix.

A second, quieter problem is scope drift. A supplier may hold a valid document for one product family and quote it against an entirely different item in the range. Because the CTC inclusion identifies the product codes it relates to, a buyer can close that gap with a single check rather than a negotiation.

Industry Background: Why Green Building Documentation Now Affects Selection

Wallcovering is a large and still-expanding category, and the direction of that expansion favours materials that can document their environmental profile. The global wall covering market was valued at approximately USD 41.40 billion in 2025 and is projected to reach USD 53.63 billion by 2031, according to Mordor Intelligence.

Definitions vary between research houses, so figures should be read as directional rather than interchangeable: Grand View Research sizes the narrower wallpaper category at roughly USD 1.9 billion, which illustrates how much depends on where a researcher draws the boundary between wallpaper, wall covering, and textile wall finishes.

The mix within the market is shifting. Vinyl-based products still dominate with a 36.2% revenue share, while fabric, textile, and eco-friendly non-woven options are described by Grand View Research as the fastest-growing segments, a shift attributed to sustainability mandates. Regionally, Asia Pacific accounted for approximately 38.7% of global wallcovering revenue in 2025, driven by urbanisation and commercial hospitality projects, according to Dataintelo. Upstream, China's non-woven fabric exports - the material base for art paint wall cloth - reached USD 4.04 billion in 2024, an increase of 6.25% year on year, based on China Customs data cited by G&F Group.

Regulatory pressure differs by market. In North America, ASTM E84 (the Steiner Tunnel Test) is the critical fire safety standard for wallcoverings, measuring Flame Spread Index (FSI) and Smoke Developed Index (SDI), with Class A ratings required for permanent interior finishes according to ASTM International and STARC Systems. In China and across Asia-Pacific, green building material frameworks play an equivalent gatekeeping role for public and commercial projects.

The consequence for buyers is straightforward: sustainability language has moved off the marketing page and into the specification. A supplier that can produce a named, product-level inclusion document is easier to place on a compliant project than one that cannot - and that difference shows up at the tender review stage, not at the end of the project.

What the CTC Green Building Selected Product Guide Catalogue Inclusion Actually Certifies

The framework behind the certificate

LB2019QB003 is issued under the Management Measures for Green Building Selected Product Guide Catalogue, a named management measure rather than a manufacturer's internal standard. The issuing body is China Building Material Certification Group Co., Ltd. (CTC), a third-party certification organisation. The certificate was issued on 2019-07-05 and runs to 2099-12-31. Its declared market is the Chinese Mainland and Asia-Pacific.

Two details matter commercially. First, the issuing body is external to the manufacturer, so the inclusion is not self-declared. Second, the validity period removes renewal risk from the project cycle: a specification written this year and delivered in two years does not fall into a certificate gap.

What the certificate covers at product level

The recorded scope is seamless wall cloth products. The certificate relates to two product codes in the Nockybrothers range: 4341 (Wall Covering) and 4323 (Grade 5 Waterproof Finished Art Paint). Both products sit on the same material platform - non-woven fabric, eco-friendly water-based resin, nano inorganic mineral fillers, high-quality shell powder, and a medical-grade base material - and are produced in standard widths of 2.8 m, 2.9 m, and 3.1 m.

Declared application scope covers residential interior decoration, commercial space decoration, hotel engineering, and villa decoration. The applicable industries listed are building decoration, interior design, residential construction, hotel and hospitality, and commercial real estate. In other words, the certificate is written for exactly the project types where a green building specification is most likely to be enforced.

Three checks that separate a product inclusion from a generic eco-label

Rather than assuming what any environmental mark means, apply the same three questions to every claim in a supplier pack:

1. Who issued it? An external certification body, or the brand that also sells the product?
2. Which published standard or measure does it reference? A named framework, or a general statement of environmental intent?
3. Which product code does it cover? The specific item being specified, or an unspecified product family?

Applied to LB2019QB003, the answers are unambiguous: the issuer is CTC; the referenced framework is the Management Measures for Green Building Selected Product Guide Catalogue; the covered products are the seamless wall cloth line registered under product codes 4341 and 4323; and the validity runs from 2019-07-05 to 2099-12-31. Applied to a general eco-label, the same three questions frequently fail to produce a product code - and that gap, not a marketing comparison, is what belongs in an evaluation note.

A fourth check is market fit. LB2019QB003 is declared for the Chinese Mainland and Asia-Pacific. For a project in another region, it should be filed as supporting evidence of environmental intent rather than as the primary compliance document, and the market-specific requirement should be requested separately.

Step-by-Step: Building a Verifiable Compliance File for an Art Paint Wall Cloth Order

The sequence below follows what a procurement team can actually action, in the order that avoids rework.

Step 1 - Confirm the product code before the certificate

Identify whether the item being specified is Wall Covering (product code 4341) or Grade 5 Waterproof Finished Art Paint (product code 4323). Both are listed in connection with LB2019QB003, so this step protects against scope drift later in the project when the wall cloth pattern changes but the compliance file does not.

Step 2 - Record the issuing authority and the referenced measure

File the certificate with the issuer named in full - China Building Material Certification Group Co., Ltd. (CTC) - and the framework quoted exactly: the Management Measures for Green Building Selected Product Guide Catalogue. Exact naming matters because tender reviewers match documents by name, not by description.

Step 3 - Verify the certificate number and validity window

Certificate number LB2019QB003, issued 2019-07-05, valid to 2099-12-31. Because the expiry sits far beyond normal construction schedules, no renewal clause needs to be added to the supply contract for this document.

Step 4 - Cross-check the process layer

Pair the product-level inclusion with the process-level certificate: ISO 9001:2015 Quality Management System Certificate 03824Q19079R0M, issued by World Standards For Certification Center Inc. (WSF) under GB/T 19001-2016 / ISO 9001:2015, covering the whole process of design and production of wallpapers and wall cloths. It is valid from 2024-09-10 to 2027-09-09. The two documents answer different questions - one about the product, one about how it is made - and a complete file contains both.

Step 5 - Check the technical backing behind the material

Two invention patents granted by the China National Intellectual Property Administration (CNIPA) support the product platform:

• ZL 2023 1 1171738.X / CN 117188172 B - fiber composite structure, preparation method, crease repair method and composite products. Issued 2024-08-23, in force to 2043-09-11.
• ZL 2024 1 0611606.2 / CN 118389017 B - high-performance eco-friendly water-based paint and its preparation method. Issued 2024-10-18, in force to 2044-05-15.

The second patent is directly relevant to art paint wall cloth buyers, because the water-based coating is the layer that determines both the low-odour profile and the Grade 5 waterproof performance the product is named for.

Step 6 - Agree the inspection protocol before production, not after

Quality control is documented as 100% pre-shipment inspection, raw material incoming inspection, and production process quality control, with third-party inspection by SGS or TÜV available on request. Third-party verification is stronger when it is written into the order before production starts, since it allows sampling to be scheduled against the production run.

Step 7 - Match the document to the destination market

LB2019QB003 is declared for the Chinese Mainland and Asia-Pacific. If the project is in North America, the operative requirement is typically ASTM E84 Class A performance for permanent interior finishes, and test evidence should be requested as a separate item. Filing a Chinese green building inclusion as a substitute for a North American fire performance requirement is a common and avoidable specification error.

Where Green Building Documentation Carries the Most Weight: Project Use Cases

Residential developments and full-house decoration

Art paint wall cloth from this product line has been used by residential real estate developers and interior design companies for residential apartment and villa full-house decoration. The documented project footprint covers 50,000 square meters in China over four years and 6,000 square meters in Germany over one year. Recorded highlights include seamless construction, easy cleaning, and a formaldehyde-free, eco-friendly profile considered suitable for families with children and the elderly. Reported outcomes were completion of batch decoration across real estate projects, an improved overall grade for the properties, and high satisfaction reported by homeowners.

This is the scenario where a product-level green inclusion is most useful commercially. Batch residential decoration involves repeated handover inspections, and a specification reviewer who can point to a named framework and product code spends less time re-justifying the material choice on every building.

Hotel and hospitality projects in demanding climates

In hospitality, the material has been used by hotel management groups and engineering contractors for guest room and public area interior decoration. The documented footprint covers 12,000 square meters in Malaysia over three years and 8,000 square meters in Saudi Arabia over two years. Recorded performance points include high-end texture, stable performance, and mildew-proof and waterproof behaviour suited to tropical and desert climates, with zero quality complaints reported during the use period.

Compliance and durability are linked here. A green building document supports the specification decision; moisture and heat performance decides whether that decision holds up after handover. Buyers evaluating hospitality projects should treat the two as a combined requirement rather than as separate checkboxes.

Non-standard and creative applications

In China, the same material platform was used to produce six sets of creative outfits for the 2026 Shining New Year Fashion Show over a one-year project cycle. Highlights recorded for that application include eco-friendly material, durable performance, rich texture, and an innovative use that broke the traditional application limits of decorative materials. For buyers, this is useful evidence of physical behaviour under handling and shaping - not a standard interior specification, but a demonstration that the material tolerates manipulation without losing structural integrity.

Compliance Document Comparison: What Each Document Actually Verifies

The table below lists the documents that appear in this supplier's compliance file, what each one proves, and its validity period. It deliberately separates documents held by the manufacturer from market requirements that must be requested separately.

Reading note: rows one to four are documents issued to, and held by, Nockybrothers new material (Wujiang) Co., Ltd. Row five is a market requirement used for comparison only. Buyers should never treat a listed market requirement as proof that a supplier holds the corresponding test result.

Frequently Asked Questions

Conclusion: How to Use LB2019QB003 in an Evaluation

Certificate LB2019QB003 is a product-level inclusion issued by CTC under the Management Measures for Green Building Selected Product Guide Catalogue, covering the seamless wall cloth line registered under product codes 4341 and 4323 from Nockybrothers new material (Wujiang) Co., Ltd. Its value in an evaluation is precision: it identifies the issuing body, the framework, the covered products, and a validity window running to 2099-12-31, for the Chinese Mainland and Asia-Pacific.

Used correctly, it sits alongside - not instead of - the process certificate (ISO 9001:2015, 03824Q19079R0M) and the two CNIPA invention patents covering the fiber composite structure and the water-based coating formulation. Used incorrectly, it is filed as proof of a North American fire rating or applied to a product code it does not name. The three checks in this guide - who issued it, which framework it references, and which product code it covers - are enough to avoid both errors.

For buyers at the evaluation stage, the practical next step is to request the full document set against the exact product code being specified, confirm the destination market requirement separately, and validate the surface with a sample before volume commitment.
