5. What lead times are typical for mass orders?
Standard orders can take 8¨C12 weeks, including material sourcing, tool setup, production, and export clearance. Expedited options may be available at a premium if the manufacturer has the capacity.
6. How can I monitor order status and inventory levels?
Secure web portals or API connections allow 24/7 visibility into committed stock, order confirmations, advanced shipping notices, and historical shipment data.
7. What environmental standards apply to sensor manufacturing?
Manufacturers must comply with restricted-substance directives such as RoHS and REACH. Wastewater treatment, air-emission controls, and hazardous-waste handling must adhere to local and international regulations.
8. How do manufacturers ensure consistent product quality?
Documented APQP, PPAP, and FMEA processes, real-time SPC monitoring, in-house testing facilities, and periodic third-party audits validate equipment calibration and process adherence.
9. What payment terms are common with Chinese suppliers?
Common terms include 30% deposit on order confirmation and 70% balance before shipment (T/T). Letters of credit are common for new relationships, while open-account terms are available for established partners.
10. How can I establish a long-term supply partnership?
Begin with a pilot order and a performance review. If satisfied with quality, lead times, and support, negotiate a multi-year contract with volume forecasts, price-protection clauses, and joint-development commitments.
