FAQ
What is your minimum order quantity (MOQ)?
We adopt a flexible MOQ policy: we support 3-5pcs MOQ for standard models to meet R&D needs, 5% discount for small quantity orders (50-100pcs), and up to 15% step discount for large quantity orders (above 1000pcs). MOQ for special package or customized materials need to be confirmed separately.
What are the payment methods? What is the billing period?
We provide diversified settlement plans: new customers support T/T prepayment of 30%, and after 3 times of cooperation, we can apply for 50% prepayment + 50% on delivery; quality customers can be open to monthly settlement of 30-60 days after evaluation.
Can you provide proof of original packaging?
All shipped materials retain complete original packaging information: including but not limited to original labels, lot numbers, MSL ratings, RoHS test reports. For bulk materials, we provide secondary vacuum packaging with test certificates.
Do you accept customer-specified substitutes?
We provide professional material substitution management service: Customers are required to provide a written confirmation letter for substitution, and we will verify the compatibility of parameters and issue an evaluation report. At the same time, we will mark the BOM change records to ensure traceability.
What support can you provide for special customized specifications of components?
We provide full-process customization services from design to mass production: Parameter customization: We support personalized adjustment of electrical characteristics, package size, etc. Sample Trial Production: Engineering samples can be provided in 2 weeks at the earliest. Small batch validation: Starting from 50-100pcs, complete test report will be provided. Mass production guarantee: establish exclusive production line and quality control standards.
How do you ensure the environmental compliance of components?
We have established a four-fold environmental protection mechanism: Raw material control: Require suppliers to provide the latest RoHS/REACH test report. Incoming material inspection: XRF screening for hazardous substances for each batch. Process control: Lead-free production lines operate independently to avoid cross contamination. Documentation Traceability: Maintain a complete chain of documents proving environmental compliance.
