Bubble Level
A bubble level (also known as a spirit level or simply a level) is an instrument designed to indicate whether a surface is horizontal (level) or vertical (plumb). It consists of a curved glass or plastic vial partially filled with a liquid, typically alcohol or mineral spirit, leaving a bubble within the vial.
Material:
- Housing: Commonly constructed from aluminum, wood, plastic, or cast iron. Aluminum is favored for its durability and resistance to corrosion, while wood is used in traditional levels. Plastic levels are lightweight and inexpensive.
- Vial: Typically made of glass or acrylic.
- Liquid: Usually alcohol-based spirits, mineral spirit, or, in some older levels, ether. The liquid's viscosity affects the damping of the bubble's movement.
- End Caps: Often made of rubber or plastic to provide shock absorption and protect the vials.
Purpose:
The primary purpose of a bubble level is to establish a true horizontal or vertical plane as a reference point for various construction, carpentry, surveying, and DIY tasks.
Function:
The functionality relies on the principle of gravity. When the level is placed on a surface, the bubble will rise to the highest point within the vial.
- Horizontal Level: Indicates a perfectly level surface when the bubble is centered between the markings on the horizontal vial.
- Vertical Level (Plumb): Indicates a perfectly vertical surface when the bubble is centered between the markings on the vertical vial(s). Some levels have vials on multiple sides to check plumb in different directions.
Usage Scenarios:
- Construction: Foundations, walls, floors, roofs, door and window frames.
- Carpentry: Installing shelves, cabinets, trim, and ensuring furniture is level.
- Masonry: Laying bricks, tiles, and stones.
- Plumbing: Ensuring pipes are correctly sloped for drainage.
- Surveying: Establishing accurate elevations and grades.
- DIY Projects: Hanging pictures, mounting televisions, and general home repairs.
Common Types:
- Spirit Level: The most common type, utilizing curved vials filled with alcohol. Available in various lengths, from small pocket levels to large, multi-vial levels.
- Post Level: Designed to attach to posts for checking plumb during installation.
- Torpedo Level: Small, compact levels often used in tight spaces.
- Line Level: A small level suspended on a line, used for leveling over longer distances.
- Digital Level: Incorporates electronic sensors to display angles numerically, offering increased precision and features like audible alerts.
- Laser Level: Projects a laser beam to create a reference line for leveling, suitable for larger projects and longer distances.
- Bull's-eye Level: A circular level used for leveling in all directions; often found on tripods for cameras and surveying equipment.
Bubble levels are instruments used to indicate whether a surface is horizontal (level) or vertical (plumb). Based on the provided reference material, the following HS codes may be relevant:
-
9017.80.00.00: This HS code falls under Chapter 90 – Instruments and apparatus which measure or check for physical quantities, meter or check flow, liquid level, or other physical quantities; and parts and accessories thereof. Specifically, it covers Other instruments with a basic duty of 5.3%, an additional tariff of 25.0%, and an additional tariff of 30.0% after April 2, 2025, resulting in a total tariff of 60.3%.
-
9031.80.80.85: This HS code is categorized under Chapter 90 – Instruments and apparatus which measure or check for physical quantities, meter or check flow, liquid level, or other physical quantities; and parts and accessories thereof. It specifically covers Measuring or checking instruments, appliances and machines, not specified or included elsewhere in this chapter; profile projectors; parts and accessories thereof: Other instruments, appliances and machines: Other Other. It has a basic duty of 0.0%, an additional tariff of 0.0%, and an additional tariff of 30.0% after April 2, 2025, resulting in a total tariff of 30.0%.
-
9031.90.91.95: This HS code falls under Chapter 90 – Instruments and apparatus which measure or check for physical quantities, meter or check flow, liquid level, or other physical quantities; and parts and accessories thereof. It specifically covers Measuring or checking instruments, appliances and machines, not specified or included elsewhere in this chapter; profile projectors; parts and accessories thereof: Parts and accessories: Other: Other Other. It has a basic duty of 0.0%, an additional tariff of 25.0%, and an additional tariff of 30.0% after April 2, 2025, plus an additional tariff of 25% for steel and aluminum products, resulting in a total tariff of 80.0%.
It is important to note that the applicable tariff will depend on the specific composition and function of the bubble level. If the bubble level contains parts made of steel or aluminum, HS code 9031.90.91.95 may be applicable, with a total tariff of 80.0%.
