What is Turkish white marble's position in the US market? Why is this a growing segment?
By 2026 Q1 data, Türkiye ranks #2 supplier in US raw marble imports (US ITA / Census Bureau sector data). Against the classic EU suppliers Italy, Spain and Greece, Türkiye's Muğla-Milas White has entered US architect office specifications thanks to production cost, scale capacity and a white+grey vein palette similar to Italian Carrara. In Manhattan, Beverly Hills and Miami Beach luxury residential tower programs, the specification 'Carrara or equivalent Turkish white marble' has been specified increasingly often over the past 5 years. This growing segment is why the US is the priority market channel for Turkish marble exports.
What will Sipahi offer at Coverings 2027 Orlando?
Coverings 2027 is the largest US and international natural stone trade fair (April 6-9, 2027, Orlando). Under Sipahi Managing Director Berkay Sipahi's visitor program, Turkish white marble + travertine supply capacity for the US market, reference project portfolio and fabrication-partner CNC network are presented. Pre-scheduled meetings with US importers, architect offices and project developers include Turkish white marble sample and trade panel walkthroughs. Following the Coverings visit, New York, LA and Miami importer visit programs are planned.
How do customs tariff and NSI processes work for Turkish marble exports to the US?
There is no free trade agreement between the US and Türkiye; however, US import customs tariff on natural stone HS 6802 is relatively low (MFN normal rate). CBP (Customs and Border Protection) certificate of origin, ASTM test reports, LEED submittal product evidence and — for Florida — FBC HVHZ certification are attached to import documents. NSI (Natural Stone Institute) member status provides trust and architect-specification reference in the US market; Sipahi is in the NSI membership pipeline in the 2026-2027 window.
How are ASTM C503 and ASTM C666 freeze-thaw standards met?
For white marble export to the US market, ASTM C503 (White Marble) is the baseline specification framework; compressive strength (ASTM C170), flexural (ASTM C880) and durability (ASTM C99) test reports are requested together. For Northeast US climate conditions (New York, Boston, Chicago), ASTM C666 freeze-thaw durability testing is mandatory. Sipahi keeps these test reports ready from producer lines on export orders and attaches them to project files along with LEED submittal product evidence.
How are LEED v4/v4.1, CalGreen and CDPH VOC standards met for Turkish white marble?
Most US prestige projects mandate or expect LEED v4/v4.1 (USGBC) green building certification; CalGreen is additionally mandatory in California, and CDPH Section 01350 is requested for indoor air quality. Turkish white marble is included in submittal processes for MR (Materials & Resources) credits with EPD (Environmental Product Declaration) product evidence. Natural stone VOC (Volatile Organic Compound) emissions are negligible and thus natively compatible with the CDPH standard; installation adhesive and sealant products should also be VOC-certified.
How is Miami-Dade FBC HVHZ (High Velocity Hurricane Zone) compliance achieved?
Miami Beach and Palm Beach oceanfront luxury tower programs fall under the FBC HVHZ (Florida Building Code, High Velocity Hurricane Zone) framework. It requires the facade cladding system (marble + mechanical anchor + insulation) to be designed and certified to withstand certain wind speeds (146+ mph). Turkish white marble is used as a slab in this system; it is designed together with a stainless-steel mechanical anchor system (Miami-Dade Notice of Acceptance / NOA certified). Sipahi coordinates this certification chain with the architect office and facade contractor alongside the marble slab in the export program.
Does Sipahi actually export to the US market, or is this in preparation?
Sipahi Marble has supplied natural stone to large-scale domestic programs since 1989. İMİB (İstanbul Mineral and Metals Exporters' Association) membership was completed in August 2026; Registry 336480. Active US export pilot programs are being prepared for the 2026-2027 window: fabrication-partner CNC network readiness, US importer and architect office meetings, DYS application, NSI membership pipeline and the Coverings 2027 Orlando visitor program are steps. Sipahi is ready for US projects with supply capacity, producer-network relationships and ASTM + LEED documentation readiness.
What is the minimum container quantity and quotation process for export orders?
For US export, one full 20' container (~20-24 tons or 300-400 m² of 2 cm slab) is the economic floor. This covers a mid-sized residential villa or a small boutique hotel program. For Manhattan tower or Miami Beach tower mega-programs, 3-10 container series are planned. Quotation process: project information via WhatsApp/email (city/state, variety, dimensions, finish, LEED + ASTM + HVHZ requirement) → written offer within 24-48 hours → samples or trade panels shipped on request → after client approval, shop drawings → fabrication-partner CNC → Adapazarı final inspection → shipment.
