Buy America eligible
Cement and cementitious materials are statutorily excluded from Buy America domestic-preference requirements (IIJA §70917(c), 2 CFR 184.3, applied at 23 CFR 635.410), so imported cement can be used on federal-aid, state, and private projects without a waiver.

Standards & specifications
Manufactured to American standards
Leading Vietnamese export mills produce cement conforming to US standards, not just domestic ones. Every Soku shipment includes mill test reports documenting conformance.
| Product | Standard | Notes |
|---|---|---|
| Portland Cement Type I / II | ASTM C150 | Low-alkali available; conformance documented by mill test reports |
| Portland Cement PCB40 / PCB50 | TCVN 6260 (Vietnam) | Strength-graded blended cement for general construction |

Proven chemistry
Representative Type I/II low-alkali results: C3A 6.69 (spec < 8), equivalent alkalies 0.58, 28-day strength 43 MPa.
SGS inspection
Independent SGS inspection at three stages of every shipment, with payment released only against the SGS certificate.
Secured terms
Irrevocable Letter of Credit, bank-to-bank documents, and a 10-day quality cure period built into every contract.
State DOT qualification, run with you
For public and DOT work, states qualify cement sources through approved-source lists backed by AASHTO-accredited mill laboratories (ASTM C1222), ASTM C150/C595 conformance documentation, shipment-level certification, and in some states NTPEP data. Several state specifications explicitly admit foreign mills that meet these requirements. Soku USA manages the approved-source application process alongside your team, state by state.
HTS 2523 base NTR duty rate: Free (USGS MCS 2026). As of July 2026, no US antidumping or countervailing duty orders specific to Vietnamese cement were in effect. Separate economy-wide trade-action surcharges apply to Vietnam-origin goods and change over time; Soku quotes are landed-cost with the current tariff layer included, and classification is always confirmed with a licensed customs broker before contract.

Common questions
FAQ
Does Vietnamese cement meet ASTM standards?
Yes. Leading Vietnamese export mills manufacture Portland cement conforming to ASTM C150 Type I and Type II, including low-alkali grades, specifically for the US market. Every Soku shipment includes mill test reports documenting conformance; project acceptance is always subject to your engineer's specification and shipment testing.
How much cement does Vietnam export?
Vietnam is the world's largest cement and clinker exporter, shipping roughly 30 million tonnes per year, and one of the world's top three producers at about 110 million tonnes annually (USGS). In 2025, Vietnam tied with Canada as the second-largest source of US cement imports at 19 percent each, behind only Turkey.
Are there US import duties on Vietnamese cement?
Cement and clinker under HTS 2523 carry a base NTR duty rate of Free, and as of July 2026 no US antidumping or countervailing duty orders specific to Vietnamese cement were in effect (USGS MCS 2026). Separate economy-wide trade-action surcharges on Vietnam-origin goods do apply and change over time, so every Soku quote is landed-cost: we price the current tariff layer in and confirm classification with a licensed customs broker before contract.
What order sizes can Soku USA handle?
From containerized bagged cement for smaller projects up to full bulk vessels of 55,000 tonnes. Tell us your volume and we will structure the right shipment.
How long does shipping to the USA take?
Typically several weeks by ocean freight depending on the destination. Documented shipments from Vietnam to the US Gulf run about five to six weeks; West Coast and Hawaii routes are shorter.
Which ports do shipments leave from?
Primarily Cam Pha, Hai Phong, and Nghi Son, Vietnam's main deep-water cement and clinker terminals. Phuc Loi shipments load at Nghi Son in vessels up to 50,000 metric tonnes.
Is imported cement Buy America eligible?
Yes. Under IIJA Section 70917(c), implemented at 2 CFR 184.3 and applied by FHWA at 23 CFR 635.410, cement and cementitious materials are excluded materials outside Buy America's domestic-preference categories, so imported cement can be used on federal-aid projects without a waiver. One precision: once cement is incorporated into a manufactured product, that product is evaluated as a whole. We provide the full citation packet with every quote.
