RFQ上为什么会有Sample Purchase标签？

买家发布RFQ后如果系统检测为小量（即最小起订量较小）则会打上Sample Purchase 标签，相关功能点：
1、在买家提交表单的成功页面有提醒：Your buying request will be marked as a “Sample Purchase” since your requested quantity is less than the supplier’s MOQ. You can modify your buying request if you have a larger order.
2、在市场中的RFQ标题后面进行打标：
标签：Sample Purchase
悬浮文案：Potential buyer with a sample purchase request.
中问大意：此RFQ可能为样品单或试单，建议供应商把握机会。
