What is HS 252329?
HS 252329 covers grey Portland cement other than white Portland cement, classified under Chapter 25 of the Harmonized System (Mineral Products). It is a hydraulic binder produced by grinding clinker — formed from sintered limestone and other raw materials — with a small proportion of gypsum. The result is the standard grey cement used across virtually every construction application worldwide.
End uses span residential and commercial construction, large-scale infrastructure projects such as roads, bridges, and dams, as well as civil engineering works including tunnels and retaining structures. Procurement teams should note that while HS 252329 is the dominant classification for standard grey cement, some national tariff schedules apply subheadings that distinguish by clinker content or packaging format — always verify the precise commodity code with your customs broker before filing import entries.
Top Sourcing Countries for Grey Portland Cement
Global supply of HS 252329 is concentrated among a handful of high-volume producers, each with distinct structural advantages:
- China (CN): The world's largest cement producer by a significant margin, with massive clinker output capacity and highly competitive domestic energy costs historically supporting export-competitive pricing. Chinese cement is cost-competitive across Southeast Asia and parts of Africa, though buyers should monitor anti-dumping measures in certain destination markets.
- India (IN): A structurally advantaged exporter to the Middle East, East Africa, and South Asia. India benefits from abundant limestone reserves and growing export infrastructure. Rising domestic construction demand can periodically tighten availability for export volumes.
- Vietnam (VN): A major regional supplier to Southeast Asian markets. Vietnam has invested heavily in clinker and cement production capacity, making it a consistent and cost-competitive origin for buyers in ASEAN and Pacific Rim markets.
- Turkey (TR): The dominant supplier to European, North African, and Middle Eastern markets. Turkish cement benefits from geographic proximity to multiple import regions, reducing freight cost — a critical factor given the product's low value-to-weight ratio.
- Indonesia (ID): An increasingly active exporter within the ASEAN region, leveraging domestic limestone availability and growing production capacity to capture market share in nearby import-dependent markets.
Because cement is heavy and low-value per tonne, freight costs can represent a substantial share of landed cost. Sourcing from the nearest structurally competitive origin is almost always more cost-effective than long-haul alternatives.
Import Duty Rates and Trade Agreements
MFN duty rates for HS 252329 vary significantly by destination market. Several major importing regions apply moderate to high MFN tariffs to protect domestic cement industries, while preferential rates are available under bilateral and regional free trade agreements. Buyers sourcing from Vietnam into ASEAN member states, for example, may benefit from ASEAN Free Trade Area (AFTA) preferential rates. Similarly, Turkish exporters supply EU markets with access to the EU-Turkey Customs Union framework for industrial goods.
Import duty rates are subject to change and must be verified directly with the relevant customs authority or via your licensed customs broker prior to shipment. Anti-dumping and countervailing duties are also active in several markets against specific origins — this is a material compliance risk that procurement teams should assess at the lane level before contracting.
Cost Drivers and Price Outlook
Grey Portland cement is one of the most energy-intensive construction materials traded globally. As of March 2026, coking coal prices have risen 14.6% month-on-month — a direct input pressure on clinker production costs for suppliers reliant on coal-fired kilns. Petcoke, a closely related fuel used widely in cement manufacturing, tends to track crude oil price movements; with Brent crude up approximately 7.4% month-on-month as of February 2026, energy cost headwinds are building across multiple major supply origins.
Limestone availability and extraction costs remain a foundational price floor driver, though this is relatively stable in established producing countries. Freight rates, particularly for bulk and breakbulk vessels on key trade lanes, are a material variable for landed cost calculations and should be monitored actively by procurement teams evaluating origin switches.
Carbon pricing is an increasingly important cost dimension. The EU Carbon Border Adjustment Mechanism (CBAM) now applies to cement imports into the European Union, requiring importers to account for the embedded carbon emissions of the product. This structurally disadvantages high-emission origins and will progressively reshape cost competitiveness among supplying countries over the medium term.
Compliance and Sourcing Considerations
Grey Portland cement (HS 252329) is not classified as a hazardous material or dual-use product, and transshipment risk is assessed as low for this commodity. However, compliance considerations remain important. Product quality and specification standards — such as EN 197-1 in Europe or ASTM C150 in the United States — must be verified at origin, as off-spec cement can create significant downstream liability in construction applications.
Country of origin documentation is particularly important where anti-dumping duties or preferential tariff claims are involved. Buyers should request mill certificates, third-party quality assurance reports, and accurate Bill of Lading descriptions to avoid customs disputes at destination.
How to Source Grey Portland Cement Efficiently
Procurement managers and freight forwarders working with HS 252329 should prioritise the following actions:
- Map your landed cost by origin, incorporating current freight rates, applicable duty rates (MFN and preferential), and CBAM costs where relevant — not just FOB price.
- Qualify multiple supply origins to build resilience against demand surges in exporting countries (particularly India and China, where domestic construction cycles can reduce export availability).
- Verify product specifications and quality certifications against destination market standards before contracting, particularly for infrastructure-grade applications.
- Monitor energy commodity indices — coal and petcoke in particular — as leading indicators of supplier price movement, allowing earlier procurement decisions.
- Confirm the correct HS subheading and any applicable trade remedy measures with a licensed customs broker in the destination country prior to each shipment.
