About Zhejiang Yongtailong Electronic Co., Ltd. - Electronic Meters Supplier in China

Zhejiang Yongtailong Electronic Co., Ltd. operates in Zhejiang province, China and currently lists five distinct meter products in its catalogue. The company focuses on electronic meters and electric power meters, which are classified under HS chapter 90, specifically the 9028.30 sub‑heading for electricity measuring instruments. All five items are designed for DIN‑rail mounting and target applications such as residential, commercial and small‑industrial power monitoring. The catalogue includes single‑phase and three‑phase configurations, with both standard and double‑tariff functionality. Each product description references the material composition of the housing and internal conductors, indicating ABS or ABS/PC plastics combined with copper and electronic PCB components.

Product Range and Specialties of Zhejiang Yongtailong Electronic Co., Ltd.

The five listed products comprise a Single Phase DIN‑Rail Energy Meter, a Three‑Phase DIN‑Rail KWH Meter, a generic Din‑rail Energy Meter (HS 9028.30), a Three‑Phase Double Tariff Meter (HS 9028.30) and a Single Phase KWh Meter (HS 9028.30). Typical specifications for these categories include voltage ratings of 230 V / 400 V, current ranges up to 100 A, accuracy classes of 0.5 % (Class 1) or 1 % (Class 2) as defined in IEC 62053‑21, and communication options such as Modbus RTU. The plastic housings (ABS or ABS/PC) provide insulation and mechanical protection, while copper internal conductors ensure reliable current sensing. Industry practice also sees optional features like pulse output, LCD display and dual‑tariff registers for time‑of‑use billing.

Trade and Export Information - Zhejiang Yongtailong Electronic Co., Ltd.

China is a major exporter of electronic power meters, and shipments under HS code 9028.30 are routinely cleared for markets in Southeast Asia, the European Union, the Middle East and Africa. Buyers commonly request CE marking for EU entry, UL certification for North America, and IECEx for hazardous locations. Export logistics usually involve 20‑ft or 40‑ft containers with meters packed in anti‑static foam and sealed in corrugated boxes, labelled with the HS code and net weight. Chinese manufacturers often work with freight forwarders using FOB or CIF terms, and they must provide a test report conforming to IEC 62053‑21 and a declaration of conformity. Import regulations in many jurisdictions also require a calibration certificate dated within six months of shipment.

Sourcing from Zhejiang Yongtailong Electronic Co., Ltd. - Buyer Guidance

When sourcing from this supplier, request the IEC 62053‑21 test report that confirms accuracy class, voltage rating and temperature performance. Ask for a CE or UL declaration of conformity, as well as a material safety data sheet for the ABS/PC housing to verify compliance with RoHS. Verify the minimum order quantity, which for electronic meters is typically 100 units per model, and confirm lead time - Chinese manufacturers generally quote 30‑45 days for production after sample approval. Request a pre‑shipment sample to assess LCD readability, pulse output stability and DIN‑rail mounting tolerances before finalizing the order.

What types of meters does Zhejiang Yongtailong Electronic list?

The catalogue includes single‑phase and three‑phase DIN‑rail energy meters, a three‑phase KWH meter, a double‑tariff three‑phase meter and a single‑phase KWh meter, all classified under HS 9028.30.

Which material is used for the meter housings?

The housings are made of ABS plastic or an ABS/PC blend, with copper used for the internal conductors and electronic PCB components for the circuitry.

What HS code applies to most of the listed meters?

Three of the products are explicitly tagged with HS code 9028.30, which covers instruments for measuring electricity.

What standard accuracy class should buyers expect?

Electronic power meters of this class are typically manufactured to IEC 62053‑21, offering accuracy classes of 0.5 % (Class 1) or 1 % (Class 2) for active energy measurement.

Which certifications are usually required for import?

Importers generally request CE marking for EU markets, UL certification for North America, and an IECEx certificate for use in hazardous zones. These are not listed as held by the supplier, so buyers should ask the supplier to provide them.

What is the usual packaging for these meters during export?

Meters are commonly packed in anti‑static foam inserts, placed inside sealed corrugated boxes, and then palletised for container loading. The packaging includes the HS code label and net weight.

What is a typical minimum order quantity and lead time?

Chinese meter manufacturers often set a MOQ of 100 units per model and a production lead time of 30‑45 days after sample approval.

How can a buyer verify the performance of the meters before full order?

Buyers should request a functional sample, review the IEC 62053‑21 test report, and check the calibration certificate for the specific batch before confirming larger volumes.
