HS Code for Biological safety cabinet

Heading 841470 specifically covers gas-tight biological safety cabinets, including those fitted with filters, provided their maximum horizontal side does not exceed 120 cm. This classification places these specialized laboratory enclosures under "Air or vacuum pumps, air or other gas compressors and fans; ventilating or recycling hoods incorporating a fan, whether or not fitted with filters; gas-tight biological safety cabinets, whether or not fitted with filters." Biological safety cabinets (BSCs) are critical equipment designed to protect laboratory personnel, the environment, and research materials from exposure to biohazards. Their inclusion here reflects their primary function as air-handling and containment devices, often incorporating sophisticated filtration systems (e.g., HEPA filters) to ensure sterility and safety. The size limitation (120 cm) is a specific delineator within this sub-heading, distinguishing smaller, more common laboratory units from larger industrial or specialized installations.

Products Included

• Class I biological safety cabinets (up to 120cm)
• Class II biological safety cabinets (Type A1, A2, B1, B2) with a maximum horizontal side not exceeding 120cm
• Class III biological safety cabinets (glove boxes) with a maximum horizontal side not exceeding 120cm
• Laminar flow hoods designed for biological containment within the specified size

Common Misclassification

841480: This code covers other air or vacuum pumps, air or other gas compressors and fans, and ventilating or recycling hoods. Larger biological safety cabinets, exceeding the 120 cm horizontal side limit, would typically fall under this broader category, as they still function as air-handling units but do not meet the specific size criterion of 841470.
902790: This code covers parts and accessories for instruments and apparatus of Chapter 90, which includes instruments and apparatus for physical or chemical analysis. While BSCs are used in conjunction with analytical instruments, they are complete functional units for containment and air handling, not merely parts or accessories.
841989: This code covers other machinery, plant or laboratory equipment, whether or not electrically heated, for the treatment of materials by a process involving a change of temperature such as heating, cooking, roasting, distilling, rectifying, sterilizing, pasteurizing, steaming, drying, evaporating, vaporizing, condensing or cooling. While some BSCs might have heating elements, their primary function is not temperature treatment but biological containment and air filtration.

FAQ

What is the HS code for a Biological safety cabinet?

The HS code for gas-tight biological safety cabinets with a maximum horizontal side not exceeding 120cm is 841470.

What is the significance of the 120cm size limit for biological safety cabinets?

The 120cm size limit in HS code 841470 specifically delineates smaller, more common laboratory-scale biological safety cabinets. Larger units, exceeding this horizontal dimension, would typically be classified under a broader heading such as 841480, which covers other air-handling equipment.
