How to Compare Transparent Rain Cover Suppliers
透明防雨布供应商比较页
Supplier comparison is meaningful only when every quotation answers the same brief. Build a fact-based scorecard for transparent PE or high-transparency PVC rather than ranking suppliers by headline price alone.
只有每份报价都回应同一份需求时，供应商比较才有意义。应为透明 PE 或高透明 PVC 建立基于事实的评分表，而不是只按表面价格排序。
1. Compare the same product scope
1. 比较同一产品范围
Separate PE and PVC quotation lines and keep finished dimensions, quantity and packing equal. If suppliers interpret the request differently, clarify the specification before assigning any score.
请分开 PE 与 PVC 报价项目，并保持成品尺寸、数量和包装一致。如供应商对需求理解不同，应先澄清规格，再评分。
2. Separate evidence from assumptions
2. 区分证据与假设
For JHY ClearRain, the supplied references show the stated PE and PVC features only. Apply the same discipline to every supplier: record what is documented, what is merely visible and what still needs written confirmation.
对 JHY ClearRain 而言，现有资料只支持已列出的 PE 与 PVC 特征。对每个供应商都应采用同一原则：记录有文件支持的内容、仅从图片可见的内容以及仍需书面确认的内容。
3. Audit the specification response
3. 审核规格响应
Check material direction, finished size, edges, corners, grommets, quantity and packing. Score omissions separately from confirmed differences. Unpublished thicknesses, tolerances and other parameters must not be guessed.
请核对材质方向、成品尺寸、包边、角部、扣眼、数量和包装。遗漏项应与已确认差异分开评分；未公布的厚度、公差和其他参数不能靠猜测。
4. Normalize commercial terms
4. 统一商务条件
Compare price only after the included product and service scope matches. Ask each supplier to state MOQ, lead time, payment, validity, packing, inspection and shipping terms. JHY ClearRain terms are not published and require current confirmation.
只有包含的产品和服务范围一致后，才能比较价格。应要求每个供应商列明起订量、交期、付款、有效期、包装、验货和运输条款。JHY ClearRain 的相关条件未公布，需按当前询盘确认。
5. Review approval methods
5. 审核确认方式
Ask how the offered construction and appearance can be approved. Do not assume that samples, reference pieces or third-party inspection are available. Confirm the method, responsibility and any cost in writing.
请询问如何确认报价结构和外观，不要默认可提供样品、参考件或第三方验货。确认方式、责任和可能费用都应书面说明。
6. Keep a decision record
6. 保留决策记录
Save the final specification, clarification replies and quotation version used for selection. A supplier score should show unresolved questions clearly so they are not mistaken for confirmed capability.
请保存用于选择的最终规格、澄清回复和报价版本。供应商评分应清楚显示未解决问题，避免将其误认为已确认能力。
