I use “SPC panels” to describe stone plastic composite panels, typically manufactured from a mineral-filled polymer core with a decorative surface and, depending on the product, a protective wear layer or backing. In commercial procurement, the term can refer to wall cladding, ceiling panels, decorative boards, or rigid flooring products, so buyers should confirm the intended application before comparing quotations. The correct purchase decision depends on panel construction, dimensions, fire and moisture requirements, installation method, surface finish, packaging, and total landed cost.

This guide explains the main SPC panel options, commonly requested specifications, suitable applications, bulk purchasing steps, and supplier evaluation criteria. I also distinguish verified project requirements from supplier-specific values because performance data can vary substantially by formulation, thickness, surface treatment, and test method.
I prepared this guide for importers, distributors, contractors, developers, interior fit-out companies, hotel and retail project buyers, and building-material wholesalers. It is especially relevant when a buyer needs repeatable specifications across multiple containers or projects rather than a small quantity for one interior. It can also help purchasing teams create a comparable request for quotation.
SPC panels are not a single standardized product category in every market. A wall panel and an SPC flooring plank may both be described as “SPC,” yet they can differ in core density, surface layer, locking system, backing, testing requirements, and intended use. I therefore recommend requesting a technical data sheet and a representative sample before approving a bulk order.
SPC usually means stone plastic composite or stone polymer composite. The core commonly combines mineral filler, often calcium carbonate, with polymer resin and additives, while the visible surface may reproduce wood, stone, marble, fabric, or other decorative designs. A typical multilayer construction can include a UV or protective coating, decorative film, wear layer, rigid core, and balancing or backing layer.
The exact formulation is supplier-specific, so the name alone does not prove a particular mineral percentage, density, waterproof rating, or fire performance. For flooring products, the relevant standard may include ISO 10582 or regional equivalents; for wall and ceiling products, the applicable requirements may instead concern reaction to fire, impact, emissions, moisture resistance, or installation-system performance. Buyers should identify the destination-market standards before asking a supplier to quote.
SPC panels are used to create a durable decorative surface while reducing some installation and maintenance demands associated with traditional materials. Depending on the product design, they can support fast interior renovation, visual consistency across rooms, and simplified cleaning. These benefits should be evaluated against substrate condition, environmental exposure, and the manufacturer’s installation instructions.
For wet rooms, I recommend treating “waterproof” as a system requirement rather than a panel-only statement. The U.S. Environmental Protection Agency explains that moisture management depends on controlling water entry, drying, and material selection across the building assembly, not merely choosing one water-resistant finish. Source: U.S. EPA, Moisture Control Fundamentals.
Rigid wall panels are commonly selected for decorative cladding and renovation applications. They may be supplied as flat boards, tongue-and-groove formats, slat-style products, or systems designed for adhesive, mechanical, or concealed installation. The buyer should confirm whether the panel requires a level substrate, separate trims, expansion gaps, or a specific adhesive.
SPC flooring generally includes a decorative layer, wear layer, rigid core, and backing, with click-lock or other installation formats. Common commercial questions include wear-layer thickness, overall thickness, dimensional stability, acoustic underlay, locking profile, and suitability for rolling loads or high-traffic areas. Flooring specifications should not be substituted for wall-panel specifications without written confirmation.
Manufacturers may offer woodgrain, stone, marble, cement, textile, solid-color, high-gloss, matte, embossed, or synchronized-texture finishes. Custom printing, embossing, edge treatment, and color matching may be possible, but availability depends on minimum order quantity, cylinder or tooling requirements, and production scheduling. I advise buyers to approve a physical color sample because monitor images do not reliably represent gloss, texture, or color under project lighting.
The following values are examples of procurement fields, not universal specifications. Actual limits should come from the supplier’s technical sheet and, where necessary, an independent laboratory report. A useful RFQ should request both the nominal value and the permitted production tolerance.
| Specification | Example procurement range or field | Why it matters |
|---|---|---|
| Panel length | Often approximately 2,400–3,000 mm for some wall formats | Affects joint layout, handling, container loading, and installation waste |
| Panel width | Often approximately 600–1,220 mm for some board formats | Influences visual scale, labor, cutting, and packaging efficiency |
| Overall thickness | Common quotation fields include 3 mm, 5 mm, 8 mm, or 10 mm | Changes rigidity, weight, trim compatibility, and impact behavior |
| Flooring wear layer | Often quoted in 0.20–0.70 mm options, depending on product class | Relevant to abrasion resistance and intended traffic level |
| Packaging quantity | Usually stated as pieces per carton and square meters per carton | Supports container planning, stock control, and damage calculations |
| Surface finish | Matte, gloss, embossed, woodgrain, stone, or customized | Determines appearance, cleaning expectations, and sample approval |
For flooring projects, ISO 10582:2017 specifies requirements for heterogeneous poly(vinyl chloride) floor coverings and provides a useful reference point for discussing product classification and testing. It does not automatically certify every SPC product, and it may not apply to wall or ceiling panels. Source: International Organization for Standardization, ISO 10582.
First, I identify whether the panels will be installed indoors, in a heated or cooled space, in a humid room, or in an area exposed to direct sunlight. I also record expected traffic, cleaning chemicals, impact exposure, rolling loads, and the condition of the substrate. These details prevent a decorative sample from being selected without considering real service conditions.
Create two lists: one for visual requirements and one for technical requirements. The visual list may include color, gloss, embossing, panel direction, joint appearance, and sample approval; the technical list may include dimensions, thickness, wear layer, dimensional stability, fire classification, emissions, moisture behavior, and installation method. This separation makes supplier comparisons more objective.

Ask which standards apply in the destination country and project type. Depending on the application, the documentation may include a technical data sheet, safety data information for relevant chemicals, test reports, installation instructions, quality-control records, and packaging specifications. Fire performance should be discussed using the exact regional classification system rather than a vague “fireproof” statement.
I recommend approving a physical sample that records the product code, color, texture, gloss, dimensions, and construction. For repeat orders, retain a control sample and define an acceptable color and surface tolerance in the purchase specification. A digital image alone is not sufficient for controlling batch-to-batch appearance.
Check the panel, adhesive or fixing method, trims, corner profiles, sealants, underlay, and substrate preparation as one system. A panel may perform differently when installed over an uneven wall, an unsuitable adhesive, or a damp substrate. Request written installation guidance and clarify which installation conditions are excluded from the supplier’s stated performance.
A practical selection framework uses five filters: application, construction, compliance, supply continuity, and landed cost. Application defines whether the product is for a wall, ceiling, floor, or specialty interior; construction defines layers, dimensions, and thickness. Compliance covers the tests and documents required by the destination market, while supply continuity covers capacity, raw-material consistency, and repeat-order control.
For a B2B project, I would compare at least three quotations using the same specification sheet. The comparison should include product price, tooling or plate charges, packaging, inspection, inland transport, export documents, freight assumptions, insurance, duties, and expected wastage. A lower unit price can become less competitive if the panel format creates excessive cutting waste or requires unavailable trims.
MOQ varies by panel size, finish, color, printing method, packaging format, and whether the order is a standard item or a custom development. I recommend asking the supplier to separate the MOQ for standard colors from the MOQ for custom colors and to state whether mixed colors can be combined in one production run. No universal MOQ should be assumed without a written quotation.
Lead time should be divided into sample approval, artwork or color confirmation, production, inspection, packing, and shipping. As a planning example, a buyer may need to budget several days for sample review and several weeks for production, but the actual schedule depends on factory loading, raw-material availability, customization, and port conditions. The purchase order should define the trigger date for production and the documents required before shipment.
Packaging deserves the same attention as the panel itself. Confirm carton dimensions in millimeters, net and gross weight in kilograms, square meters per carton, cartons per pallet, pallet dimensions, container loading assumptions, corner protection, moisture protection, and spare-panel policy. If the panel is 2,800 mm long, for example, the buyer should verify whether the packing and container plan can handle that length without unacceptable bending or damage risk.
At Novabex, I approach SPC panel sourcing as a specification-matching process rather than a one-size-fits-all product sale. As a supplier in other plastic building materials, we can discuss panel construction, surface finish, dimensions, packaging, customization, and export requirements based on the project brief. Product availability, MOQ, testing documents, lead time, and performance values must be confirmed for the specific model before a buyer places an order.
One frequent mistake is comparing panels by thickness alone. Two panels with the same nominal thickness may have different core compositions, surface layers, backing structures, densities, and installation systems. Another mistake is requesting “waterproof” or “fireproof” products without defining the test method, classification, assembly, and intended location.
Buyers also sometimes approve a sample without checking production tolerances, carton labeling, spare quantity, or replacement availability. A visually attractive sample does not confirm that every batch will match. I recommend including approved samples, technical drawings, inspection points, packaging requirements, and nonconformity procedures in the purchase documentation.
Consolidate the specification before requesting prices so each supplier quotes the same panel size, thickness, finish, packing method, and documentation. If several designs are required, ask whether they share the same core and production process; this may simplify quality control and replenishment. Where possible, use standard sizes and standard finishes for the first order, then develop customized designs after the base product has passed sample and installation review.
Calculate project quantity using net installation area plus a documented allowance for cutting, defects, and future replacement. The correct allowance depends on room geometry, panel direction, pattern repeat, opening layout, and installer skill, so I would not apply one universal percentage. For a repeat program, record actual installation waste from the first project and use that evidence to improve the next purchase.
The best SPC panel is the one whose construction and documented performance match the application, installation system, destination requirements, and purchasing plan. I recommend starting with a concise RFQ that states panel type, dimensions in millimeters, thickness in millimeters, finish, quantity in square meters or pieces, packaging requirements, destination, required documents, and target delivery window. Then compare samples, technical data, total landed cost, and supplier controls before approving production.
For a Novabex quotation, send the intended application, project quantity, preferred size and thickness, finish reference or sample, destination port or country, packaging needs, and any required compliance documents. We can then review whether a standard SPC panel or a customized solution is more appropriate and confirm the available MOQ, lead time, specifications, and commercial terms for your project.
