Material Selection Risks Beware that mixing materials like Aluminum alloys (1050, 1060, 1100) with Steel or Copper can complicate manufacturing and affect product performance; overlooking the exact alloy grade often leads to quality inconsistencies.
Specify Product Type Clearly Insist on precise product categorization—whether it's Aluminum Bottles, Hardware Parts, or Cable Conductors—to ensure the supplier aligns with your functional requirements and avoids delivery of unsuitable items.
Certification Expectations in Sourcing In practice, most reputable suppliers will provide ISO 9001 and RoHS certifications, but securing additional marks like ASTM or UL can be crucial depending on your market and compliance needs.
Payment and Origin Impact on Cost A critical question to pose concerns payment terms (T/T, L/C, Western Union) and supplier location (Beijing vs. Guangdong), as these factors significantly influence lead times, currency risk, and overall procurement costs.
