About HZH Marine Group Co., Ltd. - Marine Communication Supplier in China

China is the origin of HZH Marine Group Co., Ltd., which currently lists 15 active products across five primary categories: Radio, Microphone, Batteries & Chargers, Earphones/Headphone, and Walkie Talkie. The catalogue includes intrinsic‑safety marine radios, explosion‑proof walkie‑talkie earphones, GMDSS‑compatible batteries, and specialised throat and skull microphones. Two items carry explicit customs classifications: the CLB750G GMDSS Radio HT649 Battery is recorded under HS code 8507.80 and uses a lithium primary cell chemistry, while the Intrinsically Safe Walkie Talkie Earphones fall under HS code 8518.30 with an ABS plastic housing and silicone rubber earpiece. All products are marketed for maritime environments, with several models described as waterproof or explosion‑proof. The supplier’s trust tier is listed as “harbor”, indicating a mid‑level verification level in the platform.

Product Range and Specialties of HZH Marine Group Co., Ltd.

The catalogue comprises fifteen items ranging from intrinsic‑safety VHF radios to explosion‑proof microphones and lithium‑cell batteries. In maritime communications, radios are commonly required to meet IEC 60945 (Class A) and DNV‑GL standards, while microphones follow IEC 60065 for audio equipment. Batteries for GMDSS applications typically adhere to IEC 62133 safety standards and are supplied in compliance with HS chapter 85 classifications. Earphones and headsets used in hazardous zones are frequently certified to IECEx or ATEX requirements and are built to IP68 ingress protection.

Typical marine VHF radios operate in the 156 - 174 MHz band with output power between 5 W and 25 W, and digital models may include DSC and AIS functions. Explosion‑proof microphones often feature a rugged metal housing, a frequency response of 100 Hz - 15 kHz, and a sensitivity around - 55 dBV/Pa. Lithium primary cells used in GMDSS batteries provide a nominal voltage of 3.7 V and a capacity of 1500 mAh, packed in anti‑static containers for sea freight. Products are generally supplied in 20‑ft containers with palletized packaging, allowing 40‑60 units per pallet depending on size.

Trade and Export Information - HZH Marine Group Co., Ltd.

China is a major exporter of marine communication equipment, with shipments frequently destined for Southeast Asian ports, African coastal nations, the Middle East, and Latin American shipping fleets. HS codes 8518 (radio receivers and transmitters) and 8507 (batteries) dominate customs entries for the categories offered by this supplier, and the GMDSS battery falls under sub‑heading 8507.80. Importers typically require IECEx, ATEX, CE, and in some regions FCC or SRRC approval to satisfy safety and electromagnetic compatibility regulations. Freight is most often arranged on 20‑ft or 40‑ft containers under FOB or CIF terms, with moisture‑resistant pallets to protect electronic components.

Buyers in the offshore oil‑and‑gas sector often request additional documentation such as a Type Test Report, a Declaration of Conformity, and a Material Safety Data Sheet for lithium batteries. Maritime authorities may also demand proof of compliance with SOLAS Chapter VIII for GMDSS equipment. Packaging standards call for anti‑static inner liners, sealed outer cartons, and clear labeling of HS codes and handling instructions. Seasonal peaks occur before the start of the shipping calendar year, when vessel operators stock up on spare radios and safety accessories.

Sourcing from HZH Marine Group Co., Ltd. - Buyer Guidance

Sourcing from HZH Marine Group should begin with a request for the latest IECEx or ATEX certificates for the explosion‑proof microphones and walkie‑talkie earphones, as well as IEC 60945 test reports for the VHF radios. Buyers should verify the battery’s compliance with IEC 62133 and obtain a safety data sheet that details storage temperature range and transport classification. It is advisable to request a functional sample to confirm frequency coverage, output power, and IP rating before confirming a bulk order. Confirm that the supplier can provide CE or DNV‑GL marking copies if required by the importing country.

Typical minimum order quantities for marine radios range from 50 to 100 units, while accessories such as earphones may be ordered in batches of 200. Lead times reported by Chinese manufacturers for this product class are generally 30‑45 days after receipt of a confirmed purchase order and payment. Packaging is usually on export‑grade wooden pallets wrapped in stretch film, with each unit placed in a static‑dissipative box. Buyers should also arrange for a pre‑shipment inspection under a recognized scheme (e.g., SGS or BV) to verify conformity with the requested specifications.
