Cages Key Blocker Bags
Cages Key Blocker Bags, also known as Faraday bags for keys, are specialized pouches designed to block radio frequency (RF) signals, preventing electronic key fobs from communicating with the outside world. They are primarily used for security purposes, specifically to protect vehicles from theft via relay attacks.
Material:
These bags are constructed from multiple layers of shielding fabric. Common materials include:
- Outer Layer: Typically durable nylon or polyester for abrasion resistance and weather protection.
- Shielding Layer: Woven with metallic fibers (often copper or nickel-plated copper) to create a Faraday cage effect. This layer is the core component responsible for blocking RF signals.
- Inner Lining: Often a soft fabric to prevent scratching the key fob.
Purpose:
The primary purpose is to prevent vehicle theft through relay attacks. These attacks exploit the communication between a key fob and the vehicle's keyless entry system.
Function:
Key fobs constantly emit a low-power radio signal. A Faraday bag functions by surrounding the fob in a conductive shield. This shield intercepts and absorbs the RF signal, effectively isolating the fob from external receivers. When the signal is blocked, the vehicle cannot be unlocked or started remotely by thieves using signal amplification devices.
Usage Scenarios:
- Home Security: Storing key fobs inside the bag at home, especially overnight or when unattended for extended periods.
- Travel: Protecting key fobs during travel, particularly in areas with high theft rates or where security is a concern.
- Parking Garages/Public Areas: Using the bag when parking in public areas where the risk of relay attacks is higher.
- Vehicle Storage: Protecting key fobs during long-term vehicle storage.
Common Types:
- Single Key Fob Bags: Designed to hold one key fob. These are the most common and affordable type.
- Multiple Key Fob Bags: Larger bags with compartments for storing multiple key fobs.
- Key Fob Sleeve/Pouch: Smaller, simpler pouches that encase the key fob.
- Signal Blocking Boxes: Larger, more robust boxes that can hold multiple key fobs and other electronic devices.
- Integrated Car Key Signal Blocker: Some manufacturers offer signal blocker devices that can be directly connected to the vehicle's OBD port or keyless entry system.
Based on the provided information, the declared goods can be understood as enclosures (cages), access control items (key blockers), and containers (bags). Here's a breakdown of potentially relevant HS codes:
- 8301700000: This HS code covers padlocks and locks (key, combination or electrically operated), of base metal; clasps and frames with clasps, incorporating locks, of base metal; keys and parts of any of the foregoing articles, of base metal. The '83' chapter indicates base metal articles; '01' specifies locks, keys and clasps; '700000' further defines these items. This code is applicable if the “key blocker” component functions as a locking mechanism. The total tax rate is 42.0%.
- 3923210080: This HS code covers articles for the conveyance or packing of goods, of plastics; stoppers, lids, caps and other closures, of plastics: Sacks and bags (including cones): Of polymers of ethylene Other: With no single side exceeding 75 mm in length. The '39' chapter relates to plastics; '23' specifies articles for conveyance or packing; '210080' details sacks and bags made of ethylene polymers with dimensions not exceeding 75mm. This code is relevant if the “bags” are made of plastic and meet the size criteria. The total tax rate is 58.0%.
- 3923900080: This HS code covers articles for the conveyance or packing of goods, of plastics; stoppers, lids, caps and other closures, of plastics: Other Other. The '39' chapter relates to plastics; '23' specifies articles for conveyance or packing; '900080' covers other plastic articles. This code is applicable if the “bags” are made of plastic but do not fall under the specific criteria of 3923210080. The total tax rate is 58.0%.
