Huizhou Chungyuan Industry Development Co., Ltd.

Huizhou Chungyuan Industry Development Co., Ltd. is a China-based supplier operating from Huizhou, in the Guangdong province of southern China, an industrial corridor known for electronics manufacturing and export-oriented production. The company lists 5 active products on the B2B catalogue, all of which fall under the Computer Hardware & Peripherals and Computer Stationery & Supplies categories. The product line is concentrated entirely on electronic calculators, spanning pocket, card, desk and currency formats, with display digit counts of 8 and 12 digits across the range. None of the listed items are computer peripherals in the strict sense (such as keyboards, mice or storage devices); they sit in the office and stationery electronics segment that shares shelf space with computer supplies in B2B catalogues.

The supplier's offering covers the main form factors used in offices, schools, banks and retail environments: a compact 8-digit pocket calculator with audible key feedback, a 12-digit two-power foldable card calculator designed for portability, a 12-digit solar-powered desktop calculator intended for stationary desk use, a 12-digit dual-power electronic calculator that combines battery and solar operation, and a 12-digit dual-power currency pocket calculator aimed at foreign-exchange and small-business users. Across the five SKUs, three different power configurations appear (sound-only battery, dual battery/solar, and solar panel), and four of the five units share the 12-digit display format that is standard for accounting, tax and currency-conversion work. The product mix is narrow but covers the dominant buyer use-cases in the entry-level and mid-range calculator segment.

The catalogue is built around five electronic calculator SKUs. The display options are an 8-digit screen on the pocket sound-key model and a 12-digit screen on the remaining four products, which is the format most commonly specified for accounting, tax, banking and currency-conversion tasks. Power configurations include a battery-powered 8-digit pocket unit with sound key, a foldable card-style 12-digit calculator with two-power operation, a 12-digit solar-panel desktop calculator, a 12-digit dual-power electronic calculator, and a 12-digit dual-power currency pocket calculator. The currency-specific SKU signals a focus on foreign-exchange and small-retail buyers who need a dedicated FX function key alongside the standard arithmetic set.

In the broader calculator category, buyers typically evaluate units by display digit count (8, 10 or 12 digits), power source (battery, solar, or dual), key type (rubber dome, membrane, or mechanical), housing material (ABS plastic is standard for this segment), and the presence of business functions such as tax, currency conversion, GT (grand total), MU (mark-up), and memory keys. Common quality signals in this segment include CE marking for the European market, RoHS compliance for restriction of hazardous substances, and FCC compliance for the United States, alongside ISO 9001 quality management at the manufacturing level. Standard packaging for export is usually a blister pack or individual colour box, with inner cartons of 20 to 100 units and outer cartons sized to fit a 20 ft or 40 ft container at roughly 30,000 to 80,000 units depending on model.
