About Yuechung International Corp. - GPS Navigation System Supplier in Taiwan

Taiwan‑based Yuechung International Corp. lists five distinct electronic components in its current catalogue, giving an active product count of five. The catalogue includes Quartz Crystal, Oscillator, GPS / GNSS Modules, GPS / GNSS Antenna Modules and GPS / GNSS Receivers, each identified by its product name in the supplied data. The Quartz Crystal entry is associated with HS code 8541.60 and is described as natural or synthetic piezoelectric quartz (SiO2). The GPS / GNSS Antenna Modules are recorded under HS code 8529.10 and are built on a PCB substrate with copper trace antenna, ceramic patch element and ABS housing. The remaining three items - Oscillator, GPS / GNSS Modules and GPS / GNSS Receivers - are listed without additional HS or material details in the source data.

The supplier’s top categories are GPS Navigation System, Quartz, Electronic Oscillator and Electronic Antenna, indicating a focus on precision timing and positioning components. All five products fall under the broader electronics components segment, which is commonly classified in HS Chapter 85 for electronic circuits and Chapter 85.29 for radio‑frequency parts. The catalogue does not include any stated certifications, so buyers should verify standard compliance independently. The product list reflects a typical Taiwanese export portfolio of high‑frequency and timing devices.

Product Range and Specialties of Yuechung International Corp.

The five items in the catalogue cover core parts used in navigation and timing applications. Quartz crystals are supplied in natural or synthetic SiO2 form and are normally offered in common cuts such as AT‑cut or BT‑cut, with frequencies ranging from 10 MHz to 100 MHz and tolerance levels of ±10 ppm to ±30 ppm. Oscillators built from these crystals are typically available as fixed‑frequency crystal oscillators, temperature‑compensated (TCXO) or voltage‑controlled (VCXO) units, with output frequencies up to 200 MHz and phase‑noise specifications expressed in dBc/Hz. GPS / GNSS Modules integrate a radio front‑end, baseband processor and firmware, supporting L1/L2 bands and often conforming to SBAS standards. Antenna modules combine a PCB‑based copper trace or ceramic patch antenna with an ABS housing, delivering gains of 2‑5 dBi and VSWR below 2.0 across the GNSS bands. Receivers complete the chain by providing position, velocity and time data and are usually offered with serial (UART) or USB interfaces.

Trade and Export Information - Yuechung International Corp.

Taiwan is a major exporter of electronic components, and products such as quartz crystals, oscillators and GNSS modules are routinely shipped to North America, Europe and Southeast Asia. HS code 8541.60 places the quartz crystal within the “electronic integrated circuits” category, which commonly requires compliance with RoHS, REACH and, for wireless devices, FCC Part 15 or CE marking. HS code 8529.10 for antenna modules falls under “parts suitable for use in radio, television, navigation and radar equipment,” where buyers often request test reports for gain, VSWR and environmental durability. Typical export packaging includes antistatic bags, moisture‑barrier sealed boxes and, for bulk shipments, double‑wall cartons on 20‑ft or 40‑ft containers. Freight terms such as CIF or FOB are standard, with air freight used for small‑lot samples or time‑critical deliveries.

Sourcing from Yuechung International Corp. - Buyer Guidance

When sourcing quartz crystals from this supplier, request the frequency tolerance, temperature coefficient and crystal size (e.g., 5 mm × 5 mm) together with a RoHS compliance certificate and a material safety data sheet. For oscillators, ask for the output frequency range, phase‑noise specification, power consumption and any available test report for load regulation. GNSS modules and receivers should be accompanied by a functional test report showing acquisition time, sensitivity (e.g., - 165 dBm) and supported constellations (GPS, GLONASS, BeiDou). Because the supplier does not list certifications, buyers should verify ISO 9001 or similar quality‑management certificates before placing large orders. Typical minimum order quantities are 500 pcs for quartz crystals, 200 pcs for oscillators and 100 pcs for GNSS modules, with lead times of 15‑30 days after sample approval. Requesting a pre‑shipment inspection report (e.g., SGS or Bureau Veritas) can further reduce risk.

What types of quartz crystals does Yuechung International Corp. offer?

The catalogue lists a Quartz Crystal made from natural or synthetic piezoelectric quartz (SiO2) under HS code 8541.60. Buyers can expect common cuts such as AT‑cut with frequencies from 10 MHz to 100 MHz and tolerance levels typically between ±10 ppm and ±30 ppm.

Does the supplier provide specifications for the GPS / GNSS Antenna Modules?

Yes. The Antenna Modules are described with HS code 8529.10 and consist of a PCB substrate, copper trace antenna, ceramic patch element and ABS housing. Standard specifications include a gain of 2‑5 dBi and VSWR below 2.0 across GPS L1/L2 bands.

Which certifications should a buyer request for these electronic components?

Buyers should request RoHS compliance, REACH conformity and, for wireless items, FCC Part 15 or CE test reports. Since the supplier’s certifications are not listed, verification of ISO 9001 or equivalent quality‑management certificates is advisable.

What are typical packaging methods for the listed products?

Quartz crystals and oscillators are usually packed in antistatic bags inside moisture‑barrier sealed boxes. Antenna modules and receivers are commonly shipped in double‑wall cartons with protective foam inserts, suitable for container or air freight.

What are common minimum order quantities and lead times?

Industry practice for these components is a MOQ of around 500 pcs for quartz crystals, 200 pcs for oscillators and 100 pcs for GNSS modules or receivers. Lead times after sample approval generally range from 15 to 30 days.

How can a buyer arrange a sample request?

Buyers should contact the supplier specifying the exact part number, required quantity for the sample (often 10‑20 pcs), and request a test report or datasheet. Samples are typically dispatched by air freight with CIF terms.

What HS codes apply to the supplier’s product range?

The catalogue provides HS code 8541.60 for Quartz Crystal and HS code 8529.10 for GPS / GNSS Antenna Modules. The remaining items - Oscillator, GPS / GNSS Modules and GPS / GNSS Receivers - fall under the broader HS Chapter 85 electronic components categories.

Which markets commonly import these Taiwanese electronic components?

Major import markets include the United States, European Union countries, Japan and South Korea. These regions use the components in automotive navigation, consumer electronics, industrial automation and telecommunications equipment.
