Door Hinges

Door hinges are a crucial component in the functionality of doors, enabling rotational movement while providing support. They are typically constructed in pairs, with one half attached to the door and the other to the door frame.

Material

• Steel: Common for its strength and durability, often used in residential and commercial applications. Can be prone to corrosion if not coated.
• Stainless Steel: Offers superior corrosion resistance, suitable for high-humidity environments or exterior doors.
• Brass: Provides a decorative finish and good corrosion resistance, often found in older or high-end doors.
• Aluminum: Lightweight and corrosion-resistant, suitable for interior applications or areas where weight is a concern.
• Zinc Alloy: A cost-effective option offering moderate strength and corrosion resistance.

Purpose

The primary purpose of a door hinge is to allow a door to swing open and closed while supporting the weight of the door itself. They facilitate access and egress, and contribute to the security of a space when paired with a locking mechanism.

Function

Hinges function through a series of knuckles (leaves) that interlock. These knuckles contain a pin that allows for rotation. The design distributes the weight of the door across the frame, preventing sagging and ensuring smooth operation.

Usage Scenarios

• Residential Doors: Interior and exterior doors in homes, including bedroom doors, bathroom doors, and entry doors.
• Commercial Buildings: Office doors, storefront doors, and doors in high-traffic areas.
• Furniture: Cabinet doors, chests, and other furniture pieces requiring hinged openings.
• Industrial Applications: Heavy-duty doors in warehouses, factories, and other industrial settings.

Common Types

• Butt Hinges: The most common type, mortised into the edge of the door and frame. Available in various sizes and finishes.
• Ball-Bearing Hinges: Feature ball bearings between the knuckles for smoother operation, particularly useful for heavier doors.
• Spring Hinges: Automatically close the door after it is opened, used for self-closing doors in commercial or residential settings.
• Concealed Hinges: Hidden from view when the door is closed, providing a clean aesthetic. Often used in modern cabinetry.
• Flag Hinges: Used for wrapping around door frames, common in older installations or when a mortise is not desired.
• Continuous Hinges (Piano Hinges): Run the entire length of the door, providing maximum support and security. Often used for heavy doors or doors requiring a continuous seal.
• Casement Hinges: Used for casement windows and doors that swing outward.

Door hinges are mounting components used in the construction and operation of doors. They facilitate the pivoting movement of doors and are typically made of base metal, iron, or steel. They are applicable to both interior and exterior doors, and can be part of larger door frames or prefabricated structures.

Important Note: Regarding HS codes 7326908605 and 7326908688, while these codes cover articles of iron or steel, the applicability to door hinges specifically is less direct and may require further clarification with customs authorities.

Suggestion: When declaring door hinges, it is important to verify the material composition (steel or aluminum) as this impacts the applicable tariff rates. Additionally, be prepared to provide documentation confirming the intended use of the hinges (e.g., interior vs. exterior doors) to ensure correct classification.
