US imports under HTS 6810 at a glance
Between March and July 2026, US importers entered $932 million of articles of cement, of concrete or of artificial stone under HTS heading 6810, from 44 of the 55 origin countries covered here and across 9 ten-digit tariff lines — roughly $186 million a month of customs value under a single four-digit heading.
The heading belongs to chapter 68, articles of stone, plaster, cement and mica. Classification disputes in this range usually turn on the six-digit subheading, which is where the rates start to diverge.

Who exports articles of cement, of concrete or of artificial stone to the United States
Vietnam is the largest origin with $153 million, or 16.4% of the heading, with Thailand at 15.1% and India at 13.8%. The top three take 45.3% between them — enough concentration to matter when one origin's duty treatment changes, but not so much that a buyer has no alternative to qualify.
Mexico and Canada sit near the top of the table, and the duty numbers reflect it: Mexico entered 99.9% of its value free of duty and Canada entered 99.9% of its value free of duty. Cargo that qualifies under USMCA and is claimed correctly at entry pays nothing; cargo that does not qualify, or that is never claimed, pays the ordinary rate. The certification is the whole difference.
What importers actually paid in duty
Duty treatment is split. 74.4% of the entered value was dutiable and the rest came in free, usually under a trade agreement or a duty-free provision in the tariff schedule. CBP collected $81.9 million in all, an effective 11.8% on the dutiable value and $8.78 per $100 of goods once the free entries are counted.
The spread between origins is real. Among origins with at least 2% of the heading, China paid the most duty relative to value — $35.09 per $100 — while Mexico paid $0.01. On a $250,000 purchase order that gap is about $88,000 in duty alone, which is worth pricing into a sourcing decision rather than discovering on the entry summary.

The 10-digit lines under heading 6810
9 ten-digit lines carried trade under this heading in the period. The largest, 6810.99.00.20 (other), took 46.1% of the heading at $430 million. 6810.99.00.80, 6810.99.00.40 and 6810.11.00.70 follow. Rates diverge between those lines, so the classification your broker files is worth checking against the goods rather than carried over from the last entry.
What the duty stack looks like
The rate on an entry is not one number. It is a stack: the general (column 1) rate for the 10-digit line, less any trade-agreement preference the goods qualify for, plus whatever additional duties apply to that product and origin, all applied to the customs value declared. The $8.78 per $100 above is what that stack averaged across every entry in this heading — a benchmark, not a quote.
For the origins carrying the most volume, the per-country breakdowns go a level deeper: Vietnam (6810.99.00), Thailand (6810.99.00) and India (6810.99.00). To price a specific shipment, put your 10-digit code and country of origin into the tariff simulator.
What this means for your next shipment
The numbers above are a starting point, not the answer for a specific shipment: the rate depends on the exact 10-digit line, the origin, and any trade-agreement claim you can substantiate.

Methodology
Figures come from the U.S. Census Bureau's international trade statistics for imports for consumption — the customs value of goods entered into US commerce, not shipments in transit or goods held in bonded warehouses. The period is March–July 2026 (5 months of data), and coverage is limited to 55 major origin countries, so totals here are lower than published US-wide totals for the same heading.
Three quantities are additive and everything else is derived from them: entered customs value, dutiable value and calculated duty. Effective duty is calculated duty divided by dutiable value — the rate CBP actually applied to the part of the trade that was dutiable. Dutiable share is dutiable value divided by entered value; below 20% it means the trade entered mostly free, under a trade agreement or a duty-free provision. Duty per $100 spreads calculated duty across all entered value, which is the figure comparable between origins.
Chapter 98 and chapter 99 are excluded: those are special classification and temporary-measure provisions rather than product headings. Heading and tariff-line descriptions are the current HTS text. Values are historical and reflect duty as calculated at the time of entry; they are not a quote and not a prediction of the rate on a future shipment.

Frequently asked questions
Which countries export the most articles of cement, of concrete or of artificial stone to the United States?
Vietnam is the largest origin under HTS heading 6810, with $153 million entered between March and July 2026, or 16.4% of the heading. Thailand follows at 15.1% and India at 13.8%. Figures cover the 55 major origin countries in this dataset. Source: U.S. Census Bureau, USA Trade Online / International Trade API, imports for consumption, March–July 2026; effective duty = calculated duty ÷ dutiable value.
How much import duty is paid on articles of cement, of concrete or of artificial stone under HTS 6810?
Across all origins, 74.4% of the entered value was dutiable and CBP calculated $81.9 million of duty over the five months — an effective 11.8% on dutiable value, or about $8.78 per $100 of goods across the whole heading. Your own rate depends on the exact 10-digit line and country of origin.
Which HTS codes fall under heading 6810?
Heading 6810 covers articles of cement, of concrete or of artificial stone, whether or not reinforced. 9 ten-digit lines recorded imports in this period; the largest by value were 6810.99.00.20, 6810.99.00.80, 6810.99.00.40 and 6810.11.00.70. Duty rates differ between those lines, so the 10-digit classification matters more than the heading.
Which origin pays the lowest duty on articles of cement, of concrete or of artificial stone?
Among origins with at least 2% of the heading, Mexico paid the least duty relative to entered value — about $0.01 per $100 of goods, with 99.9% of its value entering free. Duty is only one part of landed cost, and a claim has to be substantiated at entry to be allowed.
