Combination Lock

A combination lock is a mechanical or electronic lock that requires a sequence of inputs to open. Unlike keyed locks which use a unique key, combination locks rely on a user-known combination of numbers, letters, or symbols.

Materials

Combination locks are typically constructed from:

• Metal Alloys: Brass, zinc, steel, and aluminum are common for the lock body, dials, and internal mechanisms due to their strength and resistance to tampering.
• Plastic: Often used for dials, covers, and some internal components, particularly in lower-cost models.
• Electronic Components: Digital combination locks incorporate circuits, batteries, keypads, and sometimes wireless communication modules.

Purpose

The primary purpose of a combination lock is to secure items against unauthorized access. They are used in a wide variety of applications where convenience and moderate security are desired.

Function

Combination locks function by requiring the user to manipulate a series of components in a specific order to align internal mechanisms, releasing the locking bolt or shackle. The mechanism typically involves:

• Dial(s): Rotating dials allow the user to input the combination.
• Cam(s): Internal components that move as the dial is rotated.
• Gate(s): Aligned when the correct combination is entered, allowing the shackle to release.
• Shackle: The U-shaped component that secures the lock around an object.

Usage Scenarios

• Luggage Security: Securing suitcases, backpacks, and travel bags.
• Gym Lockers: Protecting personal belongings in fitness facilities.
• School Lockers: Securing student materials.
• Bike Security: Though generally offering lower security than dedicated bike locks, they can deter casual theft.
• Storage Units: Securing smaller storage spaces.
• Padlocks: General-purpose security for gates, sheds, and other objects.
• Safes: More complex combination locks are used in safes for higher security.

Common Types

• Three-Dial Combination Lock: The most common type, featuring three rotating dials with numbers 0-39. The combination requires a sequence of three numbers.
• Four-Dial Combination Lock: Similar to three-dial locks but with four dials, offering a larger number of possible combinations.
• Digital Combination Lock: Uses a keypad to enter a numerical code. Often programmable and can store multiple combinations.
• Push-Button Combination Lock: Uses a series of buttons to enter a code.
• Programmable Combination Lock: Allows the user to change the combination easily.
• Directional Combination Lock: Requires rotating the dial clockwise and counterclockwise to specific numbers.
• Key Combination Lock: Requires both a key to operate and a combination to open. This type provides a higher level of security.

Combination locks are security devices utilizing a selection of numbers or letters to grant access. They are commonly used to secure luggage, bicycles, cabinets, and other personal belongings.

Here are the HS codes related to combination locks, based on the provided reference material:

• 83.01.00.00 - Locks, padlocks, hasps, chain, and the like, of iron or steel: This HS code covers locks made of iron or steel, which includes combination locks constructed from these materials. The first two digits (83) indicate the chapter for miscellaneous articles of base metal. The next two digits (01) specify locks, padlocks, hasps, and chains. The final two digits (00) denote all items within this category.
• 83.01.20.00 - Locks, padlocks, hasps, chain, and the like, of iron or steel: This HS code specifically covers combination locks made of iron or steel. The first two digits (83) indicate the chapter for miscellaneous articles of base metal. The next two digits (01) specify locks, padlocks, hasps, and chains. The final two digits (20) denote combination locks within this category.
• 83.01.40.00 - Locks, padlocks, hasps, chain, and the like, of iron or steel: This HS code specifically covers combination locks made of iron or steel. The first two digits (83) indicate the chapter for miscellaneous articles of base metal. The next two digits (01) specify locks, padlocks, hasps, and chains. The final two digits (40) denote combination locks within this category.
• 83.01.90.00 - Locks, padlocks, hasps, chain, and the like, of iron or steel: This HS code covers locks made of iron or steel, which includes combination locks constructed from these materials. The first two digits (83) indicate the chapter for miscellaneous articles of base metal. The next two digits (01) specify locks, padlocks, hasps, and chains.
