Common buyer questions

What materials are best for a custom 3C electronic box?

Common choices include heavy-weight rigid paperboard (1200–1800gsm) for premium presentation, corrugated or folding carton for protection, anti-static films or coatings for ESD protection, and engineered inserts (EVA foam, molded pulp, or die-cut paperboard) for secure component placement.

How should I choose between a tier-1 brand supplier and a professional source manufacturer?

Choose tier-1 suppliers for global scale, standardized certifications and synchronized multi-region launches; choose professional source manufacturers when you need lower per-unit cost, faster dieline iteration, closer factory collaboration, and reduced brand premium while still meeting FSC/quality requirements.

What lead times and MOQs can I expect for custom 3C boxes?

Typical lead times are 4–8 weeks for production after artwork and tooling approval; expedited runs may be possible. MOQs vary by supplier and complexity—expect several thousand units for custom rigid boxes, while simple folding cartons may have lower MOQs.

How do I ensure ESD and drop protection for electronic components in packaging?

Specify ESD-safe materials, anti-static films, conductive liners, and certified ESD inserts; require drop-test reports (ISTA or equivalent) and sample testing. Work with suppliers that can supply test data and production-run quality control for ESD-sensitive products.
