Supplier Sample Evaluation

供应商样品评估

New sellers order one sample, hold it, say "looks good", wire $8,400 for 1,000 units. Two months later returns hit 18%. The product was 0.4 inches off spec, the packaging failed FBA prep, the polybag had no suffocation warning. By then 600 units are stranded. A 25-point sample test before mass production catches all of this. Costs 30 minutes. Saves $3K-$10K per launch.
新卖家通常会订购一件样品,检查后觉得“看起来不错”,就转账8400美元订购1000件产品。两个月后退货率达到18%——产品尺寸比规格要求差0.4英寸,包装不符合FBA备货标准,塑料袋没有窒息警告标识。此时已有600件产品积压。而大规模生产前的25项样品测试可以提前发现所有这些问题,仅需耗时30分钟,每次产品上线可节省3000-10000美元。

When to use this

使用场景

  • Sample just arrived from a new supplier
  • Switching suppliers on an existing SKU
  • Adding a new variation (color, size) and supplier sent a sample
  • Pre-trade-show evaluation of multiple supplier candidates
  • 新供应商的样品刚到货
  • 现有SKU更换供应商
  • 添加新变体(颜色、尺寸)后供应商发来样品
  • 展会前评估多家供应商候选样品

The framework. The 25-Point Sample Test

测试框架:25项样品测试

Five sections, five points each. Each point is pass or fail. Three or more fails in any single section = full rejection, request a new sample.

Step by step

操作步骤

  1. Unbox in good light. Photograph the unboxing. Keep the box, polybag, inserts.
  2. Run Section 1 Specs. Use calipers, scale, Pantone book or hex picker. Log measurements vs spec sheet.
  3. Run Section 2 Quality. Perform the destructive tests on one sample if multiple. Otherwise functional checks only.
  4. Run Section 3 Packaging. Verify polybag mil with thickness gauge. Scan FNSKU. Read inserts for typos.
  5. Run Section 4 Compliance. Cross-reference category requirements per Amazon and FTC. Photograph any missing labels.
  6. Run Section 5 Safety. Physical inspection plus material certificate review from supplier.
  7. Score the test. Tally pass/fail. Any section with 3+ fails: REJECT, request new sample. Any single fail on safety or compliance: BLOCK PO until resolved.
  8. Write supplier message. Specific, photo-attached, actionable. Set a deadline. Re-sample required if changes are material.
  9. Run the quality check, then decide.
  1. 在充足光线环境下拆箱。拍摄拆箱过程,保留包装盒、塑料袋和内页说明。
  2. 执行第一部分规格参数测试。使用卡尺、秤、潘通色卡或取色器测量,记录测量值与规格表的对比结果。
  3. 执行第二部分产品质量测试。若有多件样品,可对其中一件进行破坏性测试;否则仅进行功能性检查。
  4. 执行第三部分包装测试。使用厚度计验证塑料袋厚度,扫描FNSKU条码,检查内页说明是否有拼写错误。
  5. 执行第四部分合规性测试。对照Amazon和FTC的品类要求交叉验证,拍摄缺失的标识。
  6. 执行第五部分安全性测试。进行物理检查,并审核供应商提供的材质证书。
  7. 统计测试得分。汇总合格/不合格项。任意部分出现3个及以上不合格项:拒收样品,要求重新提供;安全性或合规性任意一项不合格:暂停PO审批直至问题解决。
  8. 撰写供应商反馈信息。内容需具体、附带照片、可执行,并设定截止日期。若涉及重大变更,要求供应商重新提供样品。
  9. 完成质量检查后,再做决策

Worked example

示例案例

Supplier: Shenzhen Hengli, Product: bamboo cutting board 16x10x0.75 inches, sample arrived day 14 of negotiation.
Section 1 Specs: 4/5. Width measured 9.6" instead of 10" (4% off, fail). Section 2 Quality: 5/5. Pass all. Section 3 Packaging: 3/5. Polybag is 1.2 mil (fail), no suffocation warning (fail), FNSKU placement covers Country of Origin (fail). Hits the 3-fail section threshold = REJECT. Section 4 Compliance: 4/5. Country of Origin not on product, only on box (fail). Section 5 Safety: 5/5. Pass.
Verdict: REJECT. Request new sample with: width corrected to 10", polybag 1.5 mil with 5/8" suffocation warning, FNSKU placement on side panel, Country of Origin laser-etched on bottom of board. Lead time impact: +14 days. Cost impact: $0.04 per unit polybag upgrade. Without this catch: 1,000 units would have arrived, failed FBA receiving on the polybag spec, 1,000 units returned to 3PL for re-prep at $0.85 per unit = $850 rework cost plus 21 days delay.
供应商:深圳恒力,产品:16x10x0.75英寸竹制砧板,样品于谈判第14天到货。
第一部分规格参数:4/5。宽度实测9.6英寸,而非要求的10英寸(偏差4%,不合格)。 第二部分产品质量:5/5。全部合格。 第三部分包装:3/5。塑料袋厚度为1.2 mil(不合格),无窒息警告标识(不合格),FNSKU条码位置遮挡了原产国标识(不合格)。单部分出现3项不合格,触发拒收阈值 = 拒收。 第四部分合规性:4/5。原产国仅标注在外箱,未标注在产品上(不合格)。 第五部分安全性:5/5。全部合格。
结论:拒收。要求供应商重新提供符合以下要求的样品:宽度修正为10英寸,使用1.5 mil厚度且带有5/8英寸窒息警告标识的塑料袋,FNSKU条码贴在侧面板,原产国激光蚀刻在砧板底部。交付周期影响:+14天。成本影响:每个塑料袋升级增加0.04美元。若未提前发现这些问题:1000件产品到货后,因塑料袋规格不符合FBA收货标准被拒收,1000件产品需退回3PL(第三方物流)重新备货,每件成本0.85美元,总计850美元返工成本,外加21天延误。

Quality check

质量检查要点

  • Calipers used for dimension check, not a tape measure
  • Photos taken at every fail point, not just notes
  • Material certificates requested if any Section 5 doubt exists
  • Mil gauge used on polybag, not estimated
  • Supplier message specifies a deadline, not "soon"
  • 使用卡尺而非卷尺测量尺寸
  • 每个不合格项都拍摄照片,而非仅做文字记录
  • 若对第五部分安全性有疑问,要求供应商提供材质证书
  • 使用厚度计测量塑料袋厚度,而非估算
  • 供应商反馈信息需明确截止日期,而非模糊的“尽快”

Common mistakes

常见错误

  • Eyeballing dimensions. A 4% width error is invisible to the eye, fatal in returns.
  • Approving on the "looks good" test. No structured rubric = inconsistent QC.
  • Skipping Section 4 compliance. Missing CE or FCC mark on electronics = listing suppression and FBA rejection.
  • One sample, multiple variations. Different colors often come from different molds. Sample each.
  • No re-sample after fixes. Verbal promise to fix is not a verified fix. Pay $40 for a re-sample.

  • 目测尺寸:4%的宽度误差肉眼难以察觉,但会导致致命的退货问题。
  • 仅凭“看起来不错”就批准:无结构化评估标准会导致QC结果不一致。
  • 跳过第四部分合规性测试:电子产品缺失CE或FCC标识会导致商品listing被下架、FBA拒收。
  • 一件样品覆盖多个变体:不同颜色通常来自不同模具,需分别取样测试。
  • 整改后不重新取样:口头承诺整改不等于已验证整改效果,花40美元重新取样很有必要。
