Importing Persian Pietra Gray Marble Blocks from Iran to China
Persian Pietra Gray is one of Iran’s most distinctive and sought-after marble varieties. Its dark gray to black background with striking white veining makes it a favorite for luxury flooring, wall cladding, and countertops in markets worldwide — and China is the largest importer of this stone, processing Pietra Gray blocks into slabs and tiles for both domestic use and re-export. This guide walks Chinese stone importers through the entire sourcing pipeline, from understanding quarry differences and quality grades to negotiating FOB Bandar Abbas pricing, booking container shipping, and clearing customs at major Chinese stone ports. Whether you are a Shuitou processor buying your first container or an established trader expanding your block supply, the steps below will help you import Pietra Gray efficiently and profitably.
What Makes Persian Pietra Gray Unique
Persian Pietra Gray, known locally as Anarak marble, is a metamorphic limestone quarried in central Iran. Geologically, it is classified as a dense marble rather than true limestone, which gives it the hardness and polishability needed for high-traffic surfaces. The base color ranges from charcoal gray to deep black, crossed by white calcite veining that forms irregular, dramatic patterns. This contrast is what sets Pietra Gray apart from similar stones like Nero Marquina from Spain or China’s own black marbles, which tend to have more linear veining.
The stone polishes to a high gloss that deepens the black background while making the white veins pop, but it can also be honed for a matte, contemporary finish. Bulk density typically falls between 2.65 and 2.70 g/cm³, with water absorption below 0.2% by weight — figures that make it suitable for both interior flooring and exterior wall cladding in temperate climates. Importantly for Chinese processors, Pietra Gray cuts cleanly on gang saws and produces slabs with minimal blade wear compared to harder granites, helping keep processing costs competitive.
Major Quarries and Regional Quality Differences
Not all Pietra Gray is created equal. The two main production regions — Najafabad in Isfahan province and the Lar area farther south — produce stone with visibly different characteristics. Najafabad Pietra Gray tends to have a more uniform dark background with finer, more evenly distributed white veining, making it the preferred source for super and first grade blocks destined for large-format slab production. Lar Pietra Gray often shows bolder, more chaotic veining and occasional rust-colored oxidation along fractures, which some designers actually prefer for feature walls but which can complicate book-matching.
Quarry blocks are extracted using diamond wire saws and drilling equipment, then sorted at the quarry face by color consistency, vein pattern, and block geometry. A well-shaped block — roughly cubic with parallel sides — yields more slabs per ton and commands a higher FOB price. Buyers should always ask suppliers which quarry a specific lot comes from, because mixing blocks from different quarries in a single container leads to inconsistent slab color after processing.
Understanding Pietra Gray Grades and Pricing
Iranian suppliers typically classify Pietra Gray blocks into three grades. Super grade features a consistent black background with bright, well-distributed white veining and minimal fractures; this is the grade most in demand for luxury projects and commands the top of the price range. First grade has slightly more variation in background tone and vein density but still produces attractive slabs suitable for commercial flooring. Commercial grade includes blocks with heavier veining, color variation, or minor fractures — acceptable for cut-to-size tiles, split-face cladding, or projects where a rustic look is desired.
FOB Bandar Abbas pricing reflects these grades. Super grade blocks generally range from $320 to $400 per ton, first grade from $250 to $320, and commercial grade from $200 to $260. Block size also affects price: large blocks above 6 tons that yield 2-meter-plus slabs carry a premium, while smaller blocks under 3 tons are discounted because they produce narrower slabs. When requesting quotes, specify the grade, minimum block weight, and acceptable vein pattern in writing so suppliers quote against the same standard.
FOB Bandar Abbas: Pricing, Proforma Invoices, and Payment
All serious Iranian stone exporters quote Pietra Gray on an FOB Bandar Abbas basis in USD per ton. The proforma invoice should state the grade, block weight range, total tonnage, container type (20-foot or 40-foot), FOB Incoterm with the named port, and payment terms. Common payment methods include 30% advance by telegraphic transfer with the 70% balance against a copy of the bill of lading, or letter of credit for larger orders. Because of banking restrictions affecting Iran, many exporters use third-country accounts in the UAE, Turkey, or Oman — confirm the beneficiary details before transferring funds.
A single 20-foot container typically holds 25 to 28 tons of Pietra Gray blocks, while a 40-foot container can carry 26 to 28 tons due to weight limits despite the larger volume. Always ask the supplier to maximize container weight legally, as overweight containers face fines and delays at both origin and destination ports.

Container Shipping from Bandar Abbas to China
Bandar Abbas, located on the Persian Gulf in Hormozgan province, is Iran’s primary stone export port. Blocks are trucked from quarries in Isfahan and Lar to the port — a journey of roughly 500 to 700 kilometers on Iran’s inland road network — and loaded into containers at the port’s CY (container yard). The main shipping lines serving the Iran–China route include Maersk, MSC, CMA CGM, and regional carriers, with most services routing through transshipment hubs like Jebel Ali (UAE), Singapore, or Port Klang (Malaysia) before reaching China.
Transit time from Bandar Abbas to Chinese ports averages 18 to 25 days depending on the transshipment schedule. Xiamen and the neighboring Shuitou stone cluster are the primary destination ports, processing the largest volume of imported marble blocks in China. Qingdao is the second major hub, serving processors in northern China. When booking freight, confirm whether the quote includes all transshipment charges and the destination port’s THC (terminal handling charges), as these can add $200 to $400 per container if not included.
Chinese Import Documents and HS Code Classification
To clear Chinese customs, importers need a complete document set: the original bill of lading or telex release, commercial invoice, packing list, certificate of origin issued by Iran Chamber of Commerce, and in some cases a quality certificate from an inspection company. The HS code for marble blocks is 2515, specifically 2515.11 for crude or roughly trimmed marble and 2515.12 for merely cut marble blocks. Correct classification matters because it determines the duty rate and whether any quarantine or certification requirements apply.
China imposes import duties and a 13% VAT on marble blocks. The exact duty rate varies by HS subheading and country of origin; consult a licensed Chinese customs broker for the current rate and any applicable preferential tariffs. Importers must also register with Chinese customs as an importer of record and have the goods declared through a broker or electronically via the single-window system. For a full document checklist and verification tips, see our guide on Iranian natural stone export documentation.
Clearing Customs and Inland Transport to Processing Facilities
Once the container arrives at Xiamen, Shuitou, or Qingdao, the customs broker submits the document package, pays duties and VAT on your behalf, and arranges release. Container dwell time at port is typically 3 to 7 days before customs hold is lifted; demurrage charges apply after the free period, so having documents ready before arrival is critical. After release, the container is trucked to your processing facility — in Shuitou, this is often a short drayage of under 50 kilometers, while deliveries to inland factories can add several days and significant cost.
At the factory, blocks are inspected for damage, weighed, and then processed on gang saws or block cutters into slabs. Typical slab thickness is 1.6cm or 2cm for the Chinese domestic market, with larger formats for export orders. Processors should retain the certificate of origin and packing list, as these may be needed if the processed slabs are later exported and the buyer requests origin documentation.
