什么时候选国际品牌，什么时候选中国厂商

International brand or Chinese manufacturer?

• 选国际品牌：需要强品牌背书、订单量极大、对产地有硬性要求；
• Choose international: when brand backing matters, volumes are very large, or origin requirements are strict.
• 选中国厂商：需要定制灵活、中小批量、交期快、成本敏感、技术支持。
• Choose Chinese manufacturers: for flexible customization, small-to-mid batches, fast lead times, cost sensitivity, and technical support.
