Approve the specification before price先确认规格，再比较价格
Equivalent descriptions are not enough for critical components. Freeze the model, material, suffix, drawing revision and accepted alternatives.关键部件不能只依赖相似描述，应先锁定型号、材料、后缀、图纸版本和可接受的替代范围。
- Create one approved specification sheet建立统一的批准规格表
- Record brand and substitution rules记录品牌及替代规则
- Control drawing and catalogue revisions控制图纸与目录版本
Use samples and inspection intelligently合理使用样品与检验
Inspection should focus on characteristics that affect fit, function and repeat supply—not cosmetic checks alone.检验应重点关注配合、功能和重复供货，而不只是外观。
- Approve samples for new or changed items新型号或变更型号先确认样品
- Define dimensional and functional checks明确尺寸与功能检查项目
- Keep batch and packaging identification traceable保持批次与包装标识可追溯
Plan consolidation and export delivery规划整合与出口交付
Multi-item orders benefit from one packing list, coordinated readiness dates and a clearly assigned shipping responsibility.多品类订单适合统一装箱单、协调齐套日期并明确运输责任。
- Agree Incoterms and destination details确认贸易术语与目的地信息
- Define export packing and labelling明确出口包装与标签
- Review invoice, packing list and shipping documents核对发票、装箱单及运输单据
