About Changzhou Keliking Electronics Co., Ltd. - Electric Buzzers Supplier in China

Changzhou Keliking Electronics Co., Ltd. is located in Changzhou, China and currently lists five active electric buzzer products. The catalogue covers a range of electromagnetic and magnetic buzzers designed for integration in GPS devices, point‑of‑sale terminals, and other electronic equipment. Products are classified under HS chapter 85, with specific codes 8531.10, 8531.80 and 8531.90 indicating acoustic signalling devices. Materials mentioned include magnetic coil assemblies, copper windings, steel diaphragms, ABS or PBT thermoplastic housings, and neodymium or ferrite magnets. The supplier’s portfolio includes both ultra‑small SMD buzzers and micro‑small magnetic variants.

The five items comprise a GPS/POS buzzer (HS 8531.80), an SMD acoustic component without a disclosed HS code, an ultra‑small SMD electromagnetic buzzer (HS 8531.10), a micro‑small SMD magnetic buzzer (HS 8531.90), and a buzzer speaker alarm audio beeper (HS 8531.10). Each description specifies the core material composition, such as copper coil, steel diaphragm, and various polymer housings. The catalogue does not list additional certifications, leaving verification to the buyer.

Product Range and Specialties of Changzhou Keliking Electronics Co., Ltd.

The catalogue lists five electric buzzer models: a GPS/POS buzzer, an SMD acoustic component, an ultra‑small SMD electromagnetic buzzer, a micro‑small SMD magnetic buzzer, and a buzzer speaker alarm audio beeper. All items fall under HS 8531 families and are built from copper coils, steel or steel‑alloy diaphragms, ABS/PBT housings and either neodymium or ferrite magnets. In the industry, miniature SMD buzzers are typically rated for 3 V‑12 V operation, resonant frequencies between 2 kHz and 4 kHz, and sound pressure levels of 80‑100 dB at 10 mm. Common specifications also include current consumption of 10‑30 mA, operating temperature ranges of - 20 °C to +85 °C, and compliance with IEC 60068 environmental tests. Buyers often request data sheets that detail SPL, resonant frequency, voltage range and magnetic material grade.

Trade and Export Information - Changzhou Keliking Electronics Co., Ltd.

China is a leading exporter of electronic components, and electric buzzers classified under HS 8531 are routinely shipped to North America, the European Union, and Southeast Asian manufacturing hubs. Buyers of acoustic signalling devices usually require CE marking, RoHS compliance, and electromagnetic compatibility certifications such as FCC Part 15 or UL 60335, especially for devices integrated into consumer electronics. Standard export packaging involves anti‑static bags placed in bulk cartons, loaded into 20‑ft or 40‑ft containers, with FOB or CIF terms from ports like Shanghai or Ningbo. Customs authorities often reference the HS 8531 code to assess duty rates and verify that the shipment includes the required conformity documents.

Sourcing from Changzhou Keliking Electronics Co., Ltd. - Buyer Guidance

When sourcing from Changzhou Keliking Electronics, request a full product datasheet that lists operating voltage, sound pressure level, resonant frequency, current draw and temperature range. Ask for test reports covering IEC 60068 environmental tests and RoHS certificates to confirm the absence of restricted substances. Verify the material composition of the magnets (neodymium vs ferrite) and the housing polymer, and confirm that anti‑static packaging will be used for bulk shipments. Typical minimum order quantities for SMD buzzers are around 1 000 units per model, with lead times of four to six weeks after sample approval and receipt of the required compliance documents.

What types of buzzers does Changzhou Keliking Electronics offer?

The company lists five electric buzzer models, including a GPS/POS buzzer (HS 8531.80), an SMD acoustic component, an ultra‑small SMD electromagnetic buzzer (HS 8531.10), a micro‑small SMD magnetic buzzer (HS 8531.90), and a buzzer speaker alarm audio beeper (HS 8531.10).

Which HS codes apply to these buzzers?

The listed HS codes are 8531.10 for the ultra‑small electromagnetic buzzer and the audio‑beeper, 8531.80 for the GPS/POS unit, and 8531.90 for the micro‑small magnetic buzzer. Products without a specific code fall under the broader 8531 heading for acoustic signalling devices.

What material specifications are typical for these buzzers?

Materials mentioned include copper coil windings, steel or steel‑alloy diaphragms, ABS or PBT thermoplastic housings, and neodymium or ferrite magnets. Such compositions are common for miniature SMD buzzers to achieve high SPL in a compact form.

Which certifications should a buyer request?

Buyers should request CE marking, RoHS compliance, and any applicable EMC test reports such as FCC Part 15 or UL 60335. These certifications are standard for electronic components exported from China.

What are typical packaging and shipping methods?

Buzzers are usually packed in anti‑static bags, placed in bulk cartons, and loaded in 20‑ft or 40‑ft containers. FOB or CIF terms from Chinese ports such as Shanghai or Ningbo are common.

What is a typical MOQ and lead time?

For miniature SMD buzzers, manufacturers often set a minimum order quantity of 1 000 pieces per model, with a production lead time of four to six weeks after order confirmation and receipt of sample approval.

How can a buyer verify product performance?

Request a datasheet that includes operating voltage (e.g., 3‑12 V), sound pressure level (80‑100 dB), resonant frequency (2‑4 kHz) and temperature range (‑20 °C to +85 °C). Independent test reports against IEC 60068 can confirm durability and compliance.

Are there any import restrictions for these buzzers?

Importing acoustic signalling devices under HS 8531 may require compliance with local electromagnetic compatibility regulations and, in some regions, a declaration of conformity. Ensure the supplier provides the necessary certificates to clear customs.
