About Shenzhen Huahai Smart Card Co., Ltd. - Electronic Cards Supplier in China

Shenzhen Huahai Smart Card Co., Ltd. operates from Shenzhen, China and currently lists five distinct card products in its catalogue. The company is classified as an imported supplier in the electronic cards and card readers segment. Its product list includes magnetic cards, photo ID cards, PVC cards, contact IC cards and CDMA cards. Each item falls under the broader category of smart or identification cards that are commonly shipped in bulk to international buyers. The catalogue does not provide HS codes, so trade classification follows the typical HS chapters for plastic cards and electronic components.

Magnetic cards generally conform to ISO/IEC 7811 specifications for magnetic stripe encoding and are used in access control and payment systems. Photo ID cards and PVC cards are typically produced in ISO/IEC 7810 ID‑1 size (85.60 mm × 53.98 mm) with a PVC thickness of 0.76 mm. Contact IC cards follow ISO/IEC 7816 standards, offering chip‑based data storage for secure authentication. CDMA cards are a form of SIM card designed for CDMA mobile networks and align with 3GPP specifications for telecommunications. These product types are standard in global supply chains for banking, telecom, transportation and government identification programs.

Product Range and Specialties of Shenzhen Huahai Smart Card Co., Ltd.

The catalogue’s five items cover the main formats of plastic smart cards, each produced from PVC or composite PVC‑PET substrates. Magnetic stripe cards are usually encoded with three tracks at a coercivity of 250 Oe (low‑coercivity) or 400 Oe (high‑coercivity) depending on the application. Standard PVC cards are supplied in thicknesses ranging from 0.71 mm to 0.84 mm and can include optional UV or UV‑laminated finishes for durability. Contact IC cards embed a micro‑controller chip that complies with ISO/IEC 7816‑3 and often support 4 KB to 64 KB memory capacities. CDMA SIM cards are sized to the mini‑SIM (25 mm × 15 mm) or micro‑SIM (15 mm × 12 mm) form factor and are programmed according to the 3GPP 2 standard.

Photo ID cards typically integrate a printed photograph and personal data within the same PVC layer, meeting ISO/IEC 7810 ID‑1 dimensions. Buyers frequently request additional security features such as holographic overlays, laser engraving or UV printing, which can be applied during the card personalization stage. In bulk shipments, cards are commonly packed in 1,000‑card cartons, with each carton placed on palletized wooden crates for container loading. A standard 20‑foot container can accommodate approximately 200,000 ID‑1 cards, allowing efficient bulk export from Chinese manufacturing hubs.

Trade and Export Information - Shenzhen Huahai Smart Card Co., Ltd.

China ranks among the top global exporters of plastic smart cards, with Shenzhen serving as a major production hub for electronic card manufacturers. International buyers from Southeast Asia, the Middle East, Europe and North America regularly import magnetic stripe and chip cards for banking, telecom and access‑control projects. Export classifications usually fall under HS Chapter 85 for electronic components and Chapter 84 for plastic cards, and customs authorities often require conformity declarations to ISO/IEC 7810 and ISO/IEC 7816 standards. Commonly requested certifications include EMVCo approval for payment cards, 3GPP/3GPP2 compliance for SIM‑type cards, and material safety data sheets for PVC substrates. Shipments are typically packed in 1,000‑card cartons on Euro‑pallets, loaded into 20‑ft or 40‑ft containers, and shipped under FOB Shenzhen or CIF major ports such as Shanghai or Ningbo.

Importers usually ask for a commercial invoice, packing list, certificate of origin and test reports confirming magnetic coercivity or chip functionality. The typical transit time from Shenzhen to European ports is 30‑35 days, while shipments to the United States average 25‑30 days under standard maritime routes. Buyers should verify that the supplier can provide pre‑shipment inspection reports from agencies such as SGS or Bureau Veritas, especially when large volume orders are involved. Regulatory considerations may include RoHS compliance for electronic components and REACH registration for PVC materials in EU markets.

Sourcing from Shenzhen Huahai Smart Card Co., Ltd. - Buyer Guidance

Prospective buyers should request product data sheets that detail ISO/IEC 7810 ID‑1 dimensions, magnetic stripe coercivity levels and chip memory capacity for each card type. Samples of the PVC substrate, magnetic stripe and contact IC card should be examined for surface finish, thickness tolerance (±0.02 mm) and durability under bending tests. Test reports covering ISO/IEC 7816 functional verification, EMV certification for payment cards, and 3GPP2 compliance for CDMA SIM cards are standard documents to confirm quality. Prior to order confirmation, verify the supplier’s ability to meet typical minimum order quantities of 10,000 pieces per variant and to accommodate custom printing or security overlays. Clarify packaging specifications, such as 1,000 cards per carton and pallet configuration, to ensure smooth handling and accurate container loading.
