1 · TURKISH MARBLE US MARKET 2026
İMİB Export Data and HS 6802 Sub-Item Distribution
Türkiye holds one of the world's largest marble reserves. According to MTA (Turkish General Directorate of Mineral Research and Exploration), approximately 40% of the world's known natural stone reserve is located within Türkiye's borders (source: MTA Natural Stone Reserve Inventory 2023). İMİB (Istanbul Mineral Exporters' Association) statistics report Turkish natural stone exports exceeded USD 1.9 billion in 2024, with the United States among the top five export destinations (source: İMİB Export Statistics 2024). This scale means US architects, distributors and fabricators should treat Turkish stone as a strategic sourcing channel, not a spot-market supplier.
International trade classifies stone products under HS (Harmonized System) chapter 6802. The World Customs Organization (WCO) HS 2022 nomenclature defines chapter 68 sub-heading 02 as "Worked monumental or building stone" (source: WCO HS 2022 Edition). The three sub-items Sipahi uses most often:
HS 6802.21
Marble slabs
Sawn or dimensionally cut, smooth-surface marble slabs. Cladding, flooring, countertops and interior product groups fall here. Over 60% of Sipahi's main export volume is this line item.
HS 6802.91
Marble block / rough
Roughly worked or dimensioned marble blocks and slab-forms. Preferred by US-side fabricators as raw material. Heavy, lower-value-add shipment.
HS 6802.29
Other calcareous stones
Travertine, limestone and other calcite-based worked stones may fall under this sub-item. Sipahi travertine lines are classified as 6802.21 or 6802.29 depending on product form and processing level — broker verification recommended.
On the US side, these HS codes expand to full 10-digit classification under the USITC (United States International Trade Commission) HTS (Harmonized Tariff Schedule) system (see Section 4). Turkish export customs uses the HS 6-digit code; US import customs requires the HTS 10-digit code, so both sides align classification before shipment.
2 · EXPORT PROCESS STEP BY STEP
Sakarya Workshop → Istanbul Ambarli → US Arrival Port
Sipahi Marble's main production workshop is in Sakarya, Türkiye. Blocks and slabs from partner quarries are cut, honed and polished at the Sakarya workshop, then packed and dispatched to Istanbul Ambarli or Kocaeli Derince port terminals. Both ports handle large container operations on the Marmara corridor and offer weekly trans-Atlantic services (source: TCDD Taşımacılık and Marmara ports weekly schedules 2026).
Incoterm comparison — FOB / CIF / DDP
Under International Chamber of Commerce (ICC) Incoterms 2020 rules, three main options are common in Sipahi B2B export (source: ICC Incoterms 2020 Rules Publication 723E):
FOB (Free On Board)
Sipahi loads the cargo onto the designated container vessel at Istanbul Ambarli or Derince; risk and cost transfer to the buyer at that point. This is Sipahi's most common quote baseline. The buyer selects the US-side forwarder and broker directly.
CIF (Cost, Insurance, Freight)
Sipahi covers ocean freight and minimum insurance in the quote; risk transfers at loading, but cost remains with Sipahi until the arrival port. Recommended for small-to-mid-size US importers.
DDP (Delivered Duty Paid)
Sipahi delivers customs-cleared goods to the buyer's US address. All operational burden sits with Sipahi; most convenient for the buyer but highest total price. Only feasible with Sipahi partner broker and warehousing on the US side — pilot rollout planned post-Coverings 2027.
Payment — LC (Letter of Credit) and TT (Telegraphic Transfer)
LC is preferred for first-time orders and 40' HC or larger volumes. An LC is a verifiable bank payment instrument regulated under the Uniform Customs and Practice for Documentary Credits (UCP 600) (source: ICC UCP 600 Publication 600). Buyer's bank typically charges 0.5-1.5% of the USD amount as opening fee. In brief:
- LC advantage: Both parties protected by bank verification; recommended for large amounts.
- TT alternative: Under 20' FCL sample and pilot orders — 30% advance + 70% against BL copy. Saves LC opening time and fee.
- Sipahi preference: First order LC for Trade Program members; optional TT transition for repeat orders.
Container and loading — 20' FCL vs 40' HC
Turkish departure ports and US arrival ports operate ISO standard 20' FCL and 40' HC (High Cube) containers. Since marble slabs and blocks are weight-dense, the binding constraint is weight, not volume:
- 20' FCL: 19-21 tons of marble slabs + ISPM-15 stamped A-frame wooden cradles. Aligns with the ~44,000 lb (~19.9 tons) US intermodal gross weight guideline.
- 40' HC: 25-27 tons of load volume, but weight management is critical. Preferred for multi-buyer block splitting.
- LCL: For volumes below a 20' FCL — LCL (Less than Container Load); Sipahi delivers FOB Ambarli into the buyer's forwarder consolidator warehouse; a 2-3 m³ pallet minimum is typical. Sample forwarder network: DSV, DB Schenker, Kuehne+Nagel, Panalpina (DHL Global Forwarding). Sipahi carries no exclusive agreement.
3 · CUSTOMS DOCUMENTATION
7 Required Documents for US Entry — Sipahi Standard Package
On US entry, the container passes through CBP (US Customs and Border Protection) filing. The buyer's licensed customs broker manages ISF (Importer Security Filing "10+2") and the entry summary process; Sipahi provides the following 7 export-side documents as standard:
- Commercial Invoice: Buyer name, ITN (Internal Transaction Number), HS/HTS code, product description, unit and total FOB / CIF USD value, Incoterm reference. The base document for the CBP entry summary.
- Packing List: Container number, seal number, gross/net weight per pallet, block/slab traceability numbers. Reference document for CBP physical inspection.
- Bill of Lading (BL) / Airway Bill (AWB): Transport document issued by the ocean carrier or air freight agent. A negotiable BL is required for LC payment.
- Certificate of Origin: Issued and stamped by TİM (Turkish Exporters' Assembly) or the affiliated Chamber of Commerce/Industry. There is no free trade agreement between the US and Türkiye, but the origin certificate is required for the MFN (Most-Favored-Nation) tariff rate at US customs (source: USTR US-Türkiye trade relations reports).
- ISPM-15 Fumigation Certificate: Heat treatment or methyl bromide fumigation certificate for A-frame cradles and pallets. Mandatory under USDA APHIS 7 CFR Part 319.40 and FAO IPPC ISPM 15:2018; missing stamps trigger container refusal.
- California Proposition 65 Compliance Letter: For containers destined for California, a Prop 65 warning label (respirable crystalline silica, OEHHA-listed) is affixed to the packaging and an OSHA silica dust program notice is provided to the receiving fabricator.
- LEED v4.1 Support Documents (optional): For projects targeting LEED certification, Sipahi supplies SDS (Safety Data Sheet), Chain-of-Custody, ADA DCOF slip data and İMİB Registry 336480 certificate as a supplementary package. Details: LEED v4.1 Turkish Marble EPD hub.
The document package is typically delivered as PDFs to the buyer's email within 3-5 business days; original hard-copy sets required for LC bank verification are couriered separately.
4 · USITC HTS CODES
US Customs — HTS 6802.21 / 6802.91 / 6802.29 Classification
The USITC Harmonized Tariff Schedule (HTS) defines the customs classification of all products imported into the United States to 10-digit granularity (source: USITC HTS 2026 Revision, hts.usitc.gov). Turkish export customs uses the HS 6-digit code; US import customs requires the full HTS 10-digit code, so the buyer's broker performs the definitive classification.
| HTS Code | Product Description | Sipahi Usage Note |
|---|---|---|
| 6802.21 | Marble, travertine and alabaster — processed, cut slabs and formed shapes | Sipahi's primary line — cladding, flooring, countertop and interior SKUs. |
| 6802.91 | Marble, travertine and alabaster — roughly worked or merely cut, non-uniform surface | Block shipment — for US fabricators processing on their own equipment. |
| 6802.29 | Other calcareous stone (travertine, limestone, etc.) — processed slabs | Some travertine SKUs fall here; buyer broker verification recommended. |
The Sipahi quote lists the suggested HTS code per SKU on the commercial invoice draft; the buyer's licensed customs broker finalizes classification during the CBP entry summary process. Incorrect classification can trigger duty adjustments, delays or penalty exposure (source: CBP Informed Compliance Publications).
5 · TIMELINE
PO → US Delivery: 8-12 Weeks Expected Total Lead Time
The table below summarizes typical scheduling for a standard 20' FCL Sipahi order. These reference figures serve as a countdown reference for post-Coverings 2027 pilot orders where the target US delivery month is fixed:
| Phase | Duration | Note |
|---|---|---|
| Sample kit + product approval | 5-10 days | 10x10 cm physical samples + thickness/finish options. UPS/DHL air freight. |
| PO confirmation → loading | 4-6 weeks | Block cutting, slab honing/polishing, quality control, packing. |
| Sakarya → Istanbul Ambarli / Derince port | 1-2 days | Local truck transfer; container yard wait for loading. |
| Ocean transit Türkiye → US | 25-35 days | LA/Long Beach, NY/NJ, Miami, Houston arrival ports. Source: Freightos Baltic Index FBX 2026 Q3 median. |
| US Customs clearance | 3-7 days | Licensed customs broker ISF (10+2) + entry summary + CBP inspection. |
| Arrival port → buyer warehouse | 2-7 days | Intermodal truck/rail; depending on domestic US distance. |
| TOTAL (excluding samples) | 8-12 weeks | Sample kit runs before the count begins; countdown starts from PO confirmation. |
2026 Q4 note: LA/Long Beach port congestion in 2026 Q4 may increase seasonally, per Marine Exchange of Southern California anchorage metrics (source: Marine Exchange of Southern California weekly reports). Sipahi's standard recommendation is a 3-4 week buffer before the project's target delivery date.
6 · FX + PAYMENT RISK MANAGEMENT
USD Pricing, Turkish Lira Cost Base, Freight Volatility
Sipahi B2B export pricing is denominated in USD. Production costs (quarry blocks, workshop labor, energy, domestic logistics) accrue in Turkish Lira. The annual volatility of TCMB's (Central Bank of Türkiye) real effective exchange rate index has increased significantly through 2022-2026 (source: TCMB Real Effective Exchange Rate Index monthly reports). Against this backdrop, Sipahi's pricing strategy rests on three pillars:
- Buffer margin: Production cost margin management against USD-TRY volatility across the quote window. LC preference lets FX risk be coordinated with financial instruments.
- Quote validity window: Sipahi standard quotes are valid 15-30 days. This window accounts for FX volatility and quarry raw material price movement.
- Freight volatility: FBX (Freightos Baltic Index) 2026 Q3 data on the Middle East / North America corridor has shown volatility around USD 2,500-3,500 per 40' HC (source: Freightos Baltic Index weekly reports). CIF quotes confirm the ocean freight rate at the shipment date's spot rate.
- LA/Long Beach congestion buffer: If 2026 Q4 Marine Exchange data indicates rising anchorage congestion, Sipahi may offer to shift shipment dates 1-2 weeks earlier or later with the buyer's coordination.
Note: Sipahi does not provide financial advisory services. FX risk hedging (forwards, options) is managed by each side with its own commercial bank. Sipahi's role is limited to quote window flexibility and LC term adjustments.

FREQUENTLY ASKED
8 Critical Questions for US Importers and Fabricators
How many tons of marble slabs can I ship in a 20' FCL container?
A 20' FCL container typically holds 19-21 tons of marble slabs. The binding constraint is weight, not volume. In the US, intermodal container inland transport gross weight is generally managed around 44,000 lb (~19.9 tons) under Federal Bridge Formula and ocean carrier weight limits (source: US DOT FMCSA Federal Bridge Formula and Ocean Carrier Weight Limit Bulletins). A 40' HC container can hold 25-27 tons of 3 cm slabs on ISPM-15 stamped A-frame wooden cradles. Sipahi recommends 20' or 40' based on order volume and weight distribution.
Which US Customs HTS code applies to Turkish marble?
The three HTS codes Sipahi uses most often: HTS 6802.21 processed marble, travertine and alabaster slabs; HTS 6802.91 marble, travertine and alabaster (blocks and roughly worked forms); HTS 6802.29 other calcareous stone processed slabs (some travertine sub-items fall here). Exact classification is confirmed on the buyer side by the licensed customs broker; USITC HTS Search (hts.usitc.gov) is the official reference shared with the buyer's broker team (source: USITC Harmonized Tariff Schedule, 2026 Revision).
Should we go with LC (Letter of Credit) or TT (Telegraphic Transfer)?
For first-time orders and volumes of 40' HC or more, LC (Letter of Credit) is preferred — a verifiable bank instrument regulated under Uniform Customs and Practice for Documentary Credits (UCP 600) that balances risk for both parties. For pilot orders under 20' FCL, TT is an acceptable alternative with 30% advance + 70% against BL copy. LC opening fees typically range 0.5-1.5% of the USD payment on the buyer's bank (source: SWIFT and US commercial bank trade finance fee schedules); the total cost comparison is disclosed in Sipahi's quote.
Why is ISPM-15 fumigation certification required?
ISPM-15 (International Standards for Phytosanitary Measures No. 15), issued under FAO IPPC (International Plant Protection Convention), sets the heat-treatment or methyl bromide fumigation standard for wooden packaging materials (pallets, cradles, dunnage). The US, through USDA APHIS, has enforced the ISPM-15 stamp requirement on imported wood packaging since 2006 — a missing stamp can trigger container refusal and re-export costs (source: USDA APHIS 7 CFR Part 319.40 and FAO IPPC ISPM 15:2018). Sipahi loads on heat-treated, IPPC-stamped A-frame cradles and includes the fumigation certificate in the document package.
Do I need a California Prop 65 warning label for Turkish marble?
California Proposition 65 (Safe Drinking Water and Toxic Enforcement Act of 1986) requires warning labels for over 900 chemicals listed by California OEHHA (Office of Environmental Health Hazard Assessment). Cutting, grinding and honing natural stone can release respirable crystalline silica, which is on the Prop 65 list (source: California OEHHA Prop 65 List, current edition). Consequently, containers destined for California carry a Prop 65 warning label on the packaging and Sipahi provides an OSHA silica dust program notice for the receiving fabricator. The Sipahi document package includes a Prop 65 compliance letter.
How many weeks from PO to US port arrival?
For a standard 20' FCL order, total time is managed at 8-12 weeks: (1) sample kit and product approval 5-10 days, (2) PO → loading 4-6 weeks of production and QC, (3) Istanbul Ambarli or Kocaeli Derince → LA/NY/Miami/Houston ocean transit 25-35 days (source: Freightos Baltic Index FBX Middle East / North America corridor 2026 Q3 median), (4) US customs clearance 3-7 days with licensed broker support. Post-Coverings 2027 (April 6-9, 2027) pilot orders are scheduled with late-April → July delivery windows.
Which LCL forwarder do you recommend for orders below a 20' container?
For LCL (Less than Container Load), Sipahi works with the forwarder of the buyer's choice. Global operators active on the Turkey — US corridor include DSV, DB Schenker, Kuehne+Nagel and Panalpina (DHL Global Forwarding), among others. Sipahi maintains no exclusive relationship with any forwarder; Sipahi delivers FOB Istanbul Ambarli into the forwarder consolidator warehouse chosen by the buyer. LCL typically needs a minimum 2-3 m³ pallet volume; below that, sample kits or airfreight are recommended.
Does Sipahi have a booth at Coverings 2027 Orlando?
No. Sipahi Marble is NOT exhibiting at Coverings 2027 (April 6-9, 2027 at the Orange County Convention Center, Orlando). Managing Director Berkay Sipahi will attend the show as a VISITOR. As an İMİB Registry 336480 member firm, Sipahi will participate in sector panels and networking sessions. In the weeks leading up to the show, pre-scheduled meeting slots are organized for US architects, LEED consultants and fabrication partners; Sipahi Trade Program members receive priority for physical sample package sharing in Orlando (source: Coverings 2027 official exhibitor list and Sipahi 2026 Q4 export plan).
