US imports under HTS 7610 at a glance
Between March and July 2026, US importers entered $904 million of aluminum structures and parts of structures under HTS heading 7610, from 48 of the 55 origin countries covered here and across 7 ten-digit tariff lines — roughly $181 million a month of customs value under a single four-digit heading.
Heading 7610 sits in chapter 76, aluminium and articles of aluminium, so anything classified here shares a duty structure with the rest of that chapter.

Who exports aluminum structures and parts of structures to the United States
Colombia is the largest origin with $279 million, or 30.9% of the heading, with Canada at 20.4% and Mexico at 11.2%. The top three take 62.5% 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.
Canada and Mexico sit near the top of the table, and the duty numbers reflect it: Canada entered 21% of its value free of duty and Mexico entered 17.4% 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
Almost everything under this heading is dutiable: 86% of entered value carried duty, and CBP collected $283 million over the five months. The effective rate on dutiable value was 36.4%, which works out to $31.27 of duty per $100 of goods. There is no meaningful duty-free channel here — classification and origin are the only levers.
The spread between origins is real. Among origins with at least 2% of the heading, China paid the most duty relative to value — $65.11 per $100 — while Colombia paid $9.11. On a $250,000 purchase order that gap is about $140,000 in duty alone, which is worth pricing into a sourcing decision rather than discovering on the entry summary.

The 10-digit lines under heading 7610
7 ten-digit lines carried trade under this heading in the period. The largest, 7610.10.00.10 (windows and their frames), took 39.4% of the heading at $357 million. 7610.90.00.80, 7610.10.00.30 and 7610.90.00.40 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 $31.27 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: Colombia (7610.10.00), China (7610.10.00) and Vietnam (7610.90.00). 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
Classify first, confirm origin second, quote freight third. A heading like 7610 rewards that order, because the duty differences between lines and between origins are usually larger than the freight differences on the same lane. Airlift USA handles the freight and coordinates classification and entry through our licensed broker network.
For the operational side rather than the tariff side, see the Metals & Fabricated Industrial Goods guide for how this cargo moves, the China to USA lane for transit times and ports and the heading index to compare against the rest of chapter 76.

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 aluminum structures and parts of structures to the United States?
Colombia is the largest origin under HTS heading 7610, with $279 million entered between March and July 2026, or 30.9% of the heading. Canada follows at 20.4% and Mexico at 11.2%. 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 aluminum structures and parts of structures under HTS 7610?
Across all origins, 86% of the entered value was dutiable and CBP calculated $283 million of duty over the five months — an effective 36.4% on dutiable value, or about $31.27 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 7610?
Heading 7610 covers aluminum structures (excluding prefabricated buildings of heading 9406) and parts of structures (for example, bridges and bridge-sections, towers, lattice masts, roofs, roofing frameworks, doors and windows and their frames and thresholds for doors, balustrades, pillars and columns); aluminum plates, rods, profiles, tubes and the like, prepared for use in structures. 7 ten-digit lines recorded imports in this period; the largest by value were 7610.10.00.10, 7610.90.00.80, 7610.10.00.30 and 7610.90.00.40. Duty rates differ between those lines, so the 10-digit classification matters more than the heading.
Which origin pays the lowest duty on aluminum structures and parts of structures?
Among origins with at least 2% of the heading, Colombia paid the least duty relative to entered value — about $9.11 per $100 of goods, with 23% 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.
