HS Code 76.11 – Aluminium; reservoirs, tanks, vats and the like for material (not compressed or liquefied gas) of capacity over 300l, whether or not lined, heat-insulated, not fitted with mechanical, thermal equipment

HS code 7611 is a 4-digit heading in the Harmonized System that covers: Aluminium; reservoirs, tanks, vats and the like for material (not compressed or liquefied gas) of capacity over 300l, whether or not lined, heat-insulated, not fitted with mechanical, thermal equipment. HS Code 7611 covers aluminium reservoirs, tanks, vats, and similar containers for materials (excluding compressed or liquefied gas), provided they have a capacity exceeding 300 liters. These containers may or may not be lined or heat-insulated, but critically, they must *not* be fitted with mechanical or thermal equipment. This heading is essential for trade in industrial storage and processing vessels used across various sectors like food and beverage, chemical, pharmaceutical, and water treatment. The scope is strictly defined by material (aluminium), capacity (over 300L), and the absence of integrated mechanical or thermal machinery. Key sub-categories might differentiate based on lining type (e.g., epoxy, glass), insulation method, or specific design for certain industries (e.g., sanitary tanks for dairy). This classification is vital for trade compliance as the capacity limit (300L) and the absence of mechanical/thermal equipment are definitive boundaries. Exceeding 300L is a clear differentiator from smaller containers (7612), while the presence of equipment would shift classification to machinery chapters (e.g., 8419). Historically, aluminium tanks have been valued for their lightweight nature, corrosion resistance, and suitability for storing sensitive materials, contributing to efficient transport and processing in many industries. Within Chapter 76, this heading represents a finished, functional article made from aluminium, showcasing the material's application in large-scale industrial containment, distinct from basic forms or structural components.

Large aluminium water storage tanks, industrial chemical storage vats (non-gas), aluminium oil reservoirs, aluminium food processing tanks, pharmaceutical mixing vessels (without mechanical agitators), insulated aluminium milk storage tanks, brewery fermentation tanks (without cooling coils), aluminium fuel tanks for vehicles (over 300L), wine storage vats, wastewater treatment tanks, bulk liquid transport tanks (static, not vehicle-mounted), industrial dye vats, agricultural liquid fertilizer tanks, solvent storage tanks, large laboratory storage vats, potable water storage tanks for marine vessels, process tanks for pulp and paper industry, large-scale cooking oil storage tanks, chemical reaction vessels (passive, without heating/cooling), bitumen storage tanks, glycol storage tanks, molasses storage tanks, syrup storage tanks, industrial wash tanks

Several critical points lead to misclassification under 7611. The most frequent error is confusing these tanks with 'Aluminium containers for compressed or liquefied gas' under HS 7613, which are *specifically* designed for gases, whereas 7611 is for other materials. Another common mistake involves the capacity limit: if the tank is 300 liters or less, it falls under 7612 (Aluminium casks, drums, cans, boxes, etc., of a capacity not exceeding 300 l). Crucially, if the reservoir or tank is fitted with mechanical (e.g., agitator) or thermal equipment (e.g., heating coils, cooling jacket), it would likely be classified as machinery under chapters like 84 or 85 (e.g., 8419 for temperature-changing equipment), not under 7611, which explicitly excludes such fittings.

In 2025, the top exporters of HS code 7611 in UN Comtrade data were China ($38M, 15% of world exports), the Netherlands ($36M) and Germany ($34M). World exports came to about $249M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 7611 in UN Comtrade data were Germany ($29M, 15% of world imports), India ($22M) and Canada ($15M). World imports came to about $194M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 7611 is a 4-digit heading under Chapter 76 of the Harmonized System. The first 2 digits (76) identify the chapter, and digits 3-4 (11) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
