01Marble & Travertine
Türkiye is widely recognised as one of the world’s leading natural stone producers, and marble and travertine are its best-known exports. Quarries in regions such as Afyon, Bilecik, Denizli, Muğla, Burdur, Elazığ and the Marmara islands produce white, beige, grey, red and veined marbles, as well as the classic ivory, light, noce and silver travertines. For buyers looking for a Turkish marble supplier, ARAZTA helps compare quarries, processing plants and exporters in a structured way.
A good enquiry defines the stone name or colour reference, product form and size, thickness, finish and quality grade. Products include blocks, gang-saw slabs, cut-to-size tiles, steps, skirting, vanity tops and cladding panels, in finishes such as polished, honed, brushed, antique, sandblasted and bush-hammered. Travertine can be supplied filled or unfilled, vein-cut or cross-cut. ARAZTA gathers your specification, asks suppliers for photographs of actual lots, samples and technical data, and compares offers on grade, tolerance, packing and delivered cost.
Quality control is essential for natural stone because shade variation, veining and hidden defects can affect a project. We encourage sample approval, lot inspection and clear grading before shipment, and can request test data against standards such as EN 1469 for slabs and EN 12057 for modular tiles. Slabs are shipped in bundles on A-frames or crates, tiles in wooden crates or pallets. We coordinate packing, export documents and shipment from Istanbul, Izmir and other Turkish ports.

Frequently asked questions
Which Turkish marble and travertine types can you source?
We can approach suppliers of white, beige, grey, red and black marbles and ivory, light, noce and silver travertines, in blocks, slabs, tiles and fabricated products.
What slab thicknesses and finishes are available?
Slabs are commonly produced in 2 cm and 3 cm thickness, with polished, honed, brushed, antique, sandblasted and bush-hammered finishes. Other thicknesses can be requested.
How do I approve a stone before ordering?
Request samples and photographs of the actual lot. We can coordinate sample shipment and, where needed, inspection of the material before it is loaded.
How is natural stone packed for export?
Slabs are normally bundled on A-frames or in crates, and tiles are packed in wooden crates or on pallets with protection against breakage. We confirm the packing method with the supplier.
02Granite & Quartzite
Granite and quartzite are hard, dense natural stones valued for their durability, resistance to abrasion and ability to withstand weather, traffic and chemicals. They are used in kitchen countertops, façades, floors, steps, paving and landscaping. Importers searching for a granite and quartzite exporter in Türkiye will find a range of Turkish quarries and a large processing industry, and ARAZTA helps clarify which stones are quarried locally and which are processed from imported blocks.
Hard stones are specified by name or colour reference, finish, thickness and technical properties. Common finishes include polished, honed, flamed, brushed and leathered, and slabs are usually offered in 2 cm and 3 cm thickness, while paving and kerbs are cut to project dimensions. For quartzite and granite, density, water absorption, flexural strength and abrasion resistance are relevant, and ARAZTA asks suppliers for test data referencing standards such as EN 1936, EN 12372 and EN 14157 when needed.
Because many Turkish factories cut and polish blocks from several countries, origin transparency is important. We ask suppliers to state the origin of the block, the processing location and the lot information, and recommend sample approval and photo inspection of bundles. Heavy products require careful packing and container loading, with slabs bundled on A-frames and tiles on reinforced pallets. We coordinate documents, loading supervision where required and shipment from Istanbul and other Turkish ports.

Frequently asked questions
What is the difference between granite and quartzite?
Granite is an igneous rock, while quartzite is a metamorphic rock formed from sandstone. Both are hard and durable, but they differ in appearance, veining and fabrication behaviour.
Is granite from Türkiye quarried locally?
Türkiye has local granite and quartzite resources, and its factories also process blocks from other countries. We ask each supplier to state the origin so you can decide with full information.
Which finishes are suitable for outdoor use?
Flamed, brushed and bush-hammered finishes offer better slip resistance outdoors, while polished finishes are common indoors and on countertops.
Can you supply fabricated countertops?
Yes. We can request fabricated tops with edge profiles, cut-outs and polished finishes, based on your drawings and quantities.
03Porcelain & Ceramic Tiles
Türkiye is one of the larger ceramic tile producers in Europe, with modern factories in regions such as Kütahya, Bilecik, Çanakkale, Aydın and Eskişehir. Porcelain and ceramic tiles are valued for low water absorption, durability, hygiene and design flexibility, and Turkish manufacturers offer series that imitate marble, travertine, wood, concrete and textile surfaces. For importers searching for porcelain tiles in Türkiye, ARAZTA helps compare factories, ranges and commercial terms.
Tiles are described by body type, size, thickness, surface finish and technical classification. Porcelain tiles generally have water absorption below 0.5 percent and are classified under EN 14411 and ISO 13006 as group BIa. Other relevant data include abrasion resistance class (PEI), slip resistance (for example R9 to R13 or DCOF), frost resistance, chemical resistance and calibre and shade control. Formats range from 30 x 60 and 60 x 60 cm to large slabs such as 120 x 240 cm and beyond, in thicknesses from 6 to 20 mm.
ARAZTA gathers your specification and target market, requests catalogues, samples and test reports, and compares offers on grade, shade consistency, packing and price per square metre. Tiles are packed in cartons on pallets with edge protection, and we coordinate container loading, export documents and shipment from Istanbul, Izmir, Mersin and other Turkish ports so that distributors, contractors and developers receive tiles that match their approved samples.

Frequently asked questions
Which tile formats can you source from Türkiye?
Formats from 30 x 60 and 60 x 60 cm up to large slabs of 120 x 240 cm or larger, in thicknesses from about 6 to 20 mm, depending on the factory and series.
What is the difference between porcelain and ceramic tiles?
Porcelain tiles are denser with water absorption below 0.5 percent, making them suitable for floors and exteriors. Ceramic tiles have higher absorption and are common on walls and light-duty floors.
How do I avoid shade differences between batches?
Order the full quantity in one production batch where possible, and ask for shade and calibre markings. We raise this with suppliers during quotation.
Can I order private-label packaging or custom designs?
Some Turkish factories offer private-label packing and custom designs for larger volumes. We can ask for minimum quantities and lead times.
04Mosaics & Decorative Surfaces
Mosaics and decorative surfaces add texture, colour and craftsmanship to walls, floors, bathrooms, pools and feature areas. Türkiye has a long tradition of stone carving and tile making, and today its workshops and factories produce marble, travertine, glass and ceramic mosaics, carved stone panels, water-jet cut designs and three-dimensional wall surfaces. For importers and designers, ARAZTA helps identify Turkish suppliers that can deliver both catalogue products and made-to-order decorative stone.
Mosaics are specified by material, chip size, sheet size, backing, finish and colour. Marble and travertine mosaics are available in polished, honed, tumbled and antique finishes, glass mosaics in gloss and frosted versions, and ceramic mosaics in glazed and unglazed forms. Sheets are usually mounted on mesh or paper, and special shapes such as hexagon, herringbone, basketweave and fan patterns are common. Decorative carved products may require drawings, samples and approval of a prototype before production.
ARAZTA gathers your design references, requests samples and catalogues from several suppliers, and compares offers on material quality, tolerance, minimum order and lead time. Because mosaics and carved stone are delicate, we pay close attention to packing, including cartons, dividers, wooden crates and edge protection. Documents, export clearance and shipment from Istanbul and other Turkish ports are coordinated, helping architects, contractors and distributors receive decorative surfaces that arrive intact and match the approved sample.

Is a minimum order required for custom designs?
Custom designs usually have minimum quantities and longer lead times. We ask suppliers to confirm these during the quotation.
05Sanitary & Stone Basins
Stone and ceramic basins have become design features in hotels, restaurants, villas and boutique spas, while the sanitaryware that accompanies them remains a core product for every residential and commercial bathroom. Türkiye has a strong ceramic sanitaryware industry and skilled stone workshops that carve basins, bathtubs and vanity tops from marble, travertine, onyx and other natural stones. ARAZTA helps importers reach Turkish suppliers for both mass-produced and made-to-order bathroom products.
Specification begins with the product type, shape, size, material and finish. Stone vessel basins can be carved from solid blocks in polished, honed or rough-hewn finishes, with options for pop-up wastes and overflow. Ceramic washbasins, wall-hung and floor-standing toilets, bidets and pedestals are specified by dimensions, outlet type, glaze quality and water consumption class. ARAZTA gathers drawings or catalogue references, requests samples or photographs, and compares offers on quality, tolerance, breakage rates and delivered cost.
Because basins and ceramics are fragile and heavy, we pay close attention to protective packing, with foam or paper protection, partitioned cartons and wooden crates for stone pieces. Documentation can include material descriptions, test reports and conformity information for your market. We coordinate quality inspection before shipment, export documents and shipment from Istanbul and other Turkish ports, giving hospitality developers, interior designers and distributors reliable access to bathroom products that look good and arrive undamaged.

How are basins protected during shipping?
Stone basins are usually packed in foam or paper protection inside wooden crates, while ceramics are packed in partitioned cartons on pallets. We confirm packing before shipment.
06Installation Materials
A tile or stone surface is only as good as the installation materials beneath and between it. Adhesives, grouts, waterproofing membranes, levelling compounds, sealers, trims and accessories must be chosen to match the tile, the substrate and the conditions of use. For importers and contractors, ARAZTA can source these installation materials alongside the surfaces themselves, so that one supplier network supports the whole project.
Tile adhesives are classified under EN 12004, with C1 for normal cementitious adhesives and C2 for improved performance, and additional markings such as T for reduced slip, E for extended open time and S1 or S2 for deformable products. Grouts follow EN 13888, with CG1 and CG2 cementitious classes and RG reactive types, and special products exist for large-format porcelain, natural stone and swimming pools. ARAZTA collects the tile type, size, substrate and location, then requests suitable adhesives, grouts and membranes from Turkish construction chemical producers.
We also help with accessories such as levelling clips, trims and profiles, movement joints, backer boards, stone sealers, cleaners and impregnators. Requests can be combined with tile and stone orders to simplify purchasing and shipment. Packing is typically 25 kg bags on pallets for powders and pails or drums for liquids, and we coordinate safety data sheets, technical data sheets, export documents and shipment from Istanbul, so installers receive compatible materials and clear application guidance together with the tiles themselves.
Key products
- C1 cementitious tile adhesive — standard adhesive for ceramic tiles on stable substrates.
- C2 improved tile adhesive — higher-strength adhesive for porcelain and natural stone.
- C2 S1 flexible adhesive — deformable adhesive for large formats and exteriors.
- Large-format tile adhesive — high-bed adhesives for slabs and heavy tiles.

What adhesive should I use for large-format porcelain?
Large formats usually need a C2 adhesive with improved deformability, often C2 S1, applied with the correct notched trowel. We can request suitable adhesives from Turkish producers.
Can you supply grout and adhesive together with tiles?
Yes. Tiles, adhesives, grouts, membranes and accessories can be requested together and shipped in the same container to simplify logistics.
Do installation materials need technical data sheets?
Yes. Technical and safety data sheets define coverage, open time, curing and application limits. We request them from suppliers before ordering.
How are powder adhesives packed for export?
In 25 kg bags on pallets, stretch-wrapped for protection against moisture. We confirm packing and shelf life with the supplier.
Why Source from Türkiye
Türkiye sits where Europe, Asia and the Middle East meet, and that position has helped it become one of the world’s leading origins for natural stone and ceramic surfaces. For importers searching for a Turkish marble supplier, porcelain tiles in Türkiye or stone slabs in Istanbul, ARAZTA provides a structured way to compare Turkish suppliers, quarries, factories and exporters. ARAZTA’s B2B sourcing Türkiye service researches suppliers, clarifies specifications and supports the commercial process from first enquiry to loaded container.
The raw material base is a major strength. Quarries across Anatolia produce marble, travertine, limestone and other natural stone in a wide range of colours, and modern processing plants cut, polish and calibrate slabs and tiles. The ceramic industry operates large, automated factories that produce porcelain tiles, wall tiles, large-format slabs and sanitaryware. Many suppliers work to EN, ISO and ASTM test methods and serve demanding customers in Europe, the Gulf, North America and Africa. ARAZTA asks for test reports, catalogues and samples, and clarifies whether a company quarries, manufactures or only trades.
Design range and flexibility add to the appeal. Turkish factories regularly develop new surfaces that follow international trends, from marble-look and wood-look porcelain to textured outdoor pavers, and stone workshops can fabricate vanity tops, steps, mosaics and carved elements to drawings. Many suppliers accept mixed-container orders and are used to working with distributors, contractors and architects, which helps buyers test the market before committing to large volumes.
Cost is often a deciding factor. Integrated production, local energy and raw materials and efficient factories allow competitive prices on stone and tile, and the Customs Union with the European Union simplifies trade in industrial goods. Transit times to Europe, the Middle East and North Africa are shorter than from Far Eastern origins, which helps developers and distributors manage project schedules and stock levels.
Logistics infrastructure supports exports of heavy cargo. Istanbul and the Marmara ports including Ambarlı handle containers, while Izmir, Aliağa and Mersin serve stone and ceramic regions in the west and south. Road and rail links connect factories to ports, and Turkish exporters are used to loading slabs on A-frames, palletising tiles and preparing commercial invoices, packing lists, certificates of origin and A.TR or EUR.1 documents where applicable.
If your project also requires additives, adhesives or technical hardware, we can source construction chemical raw materials and industrial equipment and components through the same Istanbul-based process, so one coordinated Istanbul export plan can cover your wider construction materials Türkiye needs.
