供应商报价一家比一家低，用起来一家比一家差。8条标准先立，别靠关系靠数据。
报价一家比一家低，用起来却一家差
TPE 原料采购，标准是护身符：资质、数据、批次。结论先给：8条标准筛掉八成供应商——标准，是采购的筛子。
TPE原料采购最大的坑：标准不先立起来，踩坑就是家常便饭——标准，是采购的护身符。
采购是成本关：会筛供应商，省的是真金。不会筛，踩的是坑——采购，是企业的考题。
采购靠数据不靠关系，为什么先立标准
采购要数据：物性表、检测报告。数据，是采购的依据。
采购要资质：营业执照、认证。资质，是供应商的身份证。
采购要批次：批次可追溯。批次，是质量的账本。
资质、数据、批次，8条筛什么
一查资质：执照认证齐全。资质缺，直接筛掉——资质，是头一筛。
二看数据：物性表对得上。数据假，别合作——数据，是第二筛。
三问批次：批次可追溯。批次乱，风险高——批次，是第三筛。
四核产能、五查口碑、六看案例、七比服务、八定账期——八条合起来，筛掉八成。
8条标准，一张表对照清楚
| 标准 | 检查 | 判断 |
|---|
| 资质 | 执照 | 必查 |
| 数据 | 物性 | 必查 |
| 批次 | 追溯 | 必查 |
| 产能 | 规模 | 必查 |
| 口碑 | 案例 | 必查 |
表格读法：标准逐条核，不合格就筛，缺项的直接进淘汰栏。
标准立住，坑就少了。
筛掉忽悠的，留下能供的
| 项目 | 要求 | 判断 |
|---|
| 资质 | 齐全 | 核验 |
| 数据 | 实测 | 核验 |
| 批次 | 可溯 | 核验 |
| 服务 | 响应 | 核验 |
表格读法：筛选一项项核，风险看得见，资质和批次都要查原件。
标准，是采购的筛子。
靠关系定供应商，出问题没人管
坑一：靠关系。关系户报价好看，交货时才发现资质缺项——标准必立。
坑二：只看价格。踩坑——数据必核。
坑三：批次不核。风险——批次必查。
资质、溯源、良率——选型前问清
三问：什么资质、什么数据、什么批次。一验：小批试用实测——三问一验，供应商底细清楚。
标准验证要先行：先把资质、物性、追溯八条列成检查表，再谈价格——标准，是采购的护身符。
留样要成习惯：每批留样，物性按批次复测。批次换料先对比再放量——批次稳，客诉少。
掺假、波动、跑路：对照一张表
| 现象 | 原因 | 对策 |
|---|
| 踩坑 | 没标准 | 立标准 |
| 数据假 | 不实测 | 要报告 |
| 批次乱 | 不追溯 | 锁批次 |
| 价格虚 | 没对比 | 多比价 |
| 客诉 | 服务差 | 换供应商 |
靠关系拿料，关系一断料就断——采购靠数据不靠人情。 关系报价好看，真到交货时靠不住。
采购避坑先过三关：物性表带不带测试条件、追溯能不能查到批次、打样快不快看研发储备。
缺项淘汰、拖沓淘汰，剩两家再认样，别一家谈到底。
资质、数据、批次、产能、口碑五条必查。 执照、物性、追溯一项不落，缺一项就进淘汰栏，留两三家再认样。
供应商是长期队友，不是一锤子买卖。 响应快、能调工艺的优先，只卖料不跟机的出问题自己扛，服务要写进评估。
8条标准逐条过、小批试产良率达标，供应商从一堆报价里筛出靠谱那两家。 数据说话别拍脑袋，关系不能当验收。

科隆客户案例：交期紧性能对不上，重调配方补认证
南京一家改性料应用厂，交期紧，现货牌号性能对不上。科隆配合重调配方（油/助剂/填充比例），性能对齐，通过第三方检测并补齐认证。配方重调，交期从源头抢回来——性能对不上，先看配方体系。
小结
TPE原料采购的避坑，标准先立，数据再核，八条筛子摆出来，标准才是筛子。
Supplier quotes are lower than the last, but each one is worse in use. Set 8 standards first, don't rely on connections or data.
Quotes are lower than the last, but the results are worse
TPE Raw material procurement is a shield for standards: qualifications, data, batches. Conclusion first: 8 standards filter out 80% of suppliers — standards are the sieve for procurement.
TPE biggest pitfall in raw material procurement: if standards aren't set first, falling into pitfalls becomes routine — standards are the protection shield for procurement.
Procurement is cost control: If you can filter suppliers, you save real money. If you don't know how to screen, you fall into a trap — procurement is a test for companies.
Procurement relies on data, not connections, why set standards first ?
Procurement needs data: physical property tables and test reports. Data is the basis for procurement.
Procurement requires qualifications: business licenses and certifications. Qualifications are the supplier's ID card.
Procurement requires batches: batch is traceable. Batches are the ledger of quality.
Qualifications, data, batches—what are the 8 items to screen ?
One-check qualification: complete licenses and certifications. If qualifications are lacking, just filter them out—qualification is the first screen.
Second-check data: physical property tables match. If the data is fake, don't cooperate—data is the second screen.
Three-Ask Batch: Batch can be traced. Batch chaos and high risk—batches are the third screening.
Four-core capacity, five-point reputation check, six-point case review, seventh-level service comparison, eight-point fix-book period—eight points combined can filter out eighty percent.
8 standards, one form for clear comparison
| standard | inspection | judgment |
|---|
| qualification | license | mandatory check |
| data | physical properties | mandatory check |
| Batch | Traceability | Mandatory Check |
| Capacity | Scale | Mandatory Check |
| Reputation | Case | Mandatory Check |
Table Reading: Standard checks item by item, screening for nonconformities, and sending missing items directly into the elimination section.
Standard, and there are fewer pitfalls.
Filter out the hype, keep what can be supplied
| Project | Requirement | Judgment |
|---|
| Qualification | Complete | Verification |
| Data | Actual testing | Verification |
| Batch | Traceable | Verification |
| Service | Response | Verification |
Table Reading: Screening item by item for verification, risks are visible, and both qualifications and batches must be checked as originals.
Standards are the sieve for procurement.
Rely on connections to determine suppliers; if problems arise, no one cares .
Pitfall One: Relying on connections. Connections offer attractive quotes, but only discover missing qualifications at delivery—standards must be established.
Pitfall Two: Only look at price. Pitfall—data must be verified.
Pitfall Three: Batch verification is not required. Risk—Batch must be checked.
Qualifications, traceability, yield—ask clearly before selecting
Triple Questions: What qualifications, data, and batches. First Inspection: Small batch trial testing—Three questions and one inspection, supplier background is clear.
Standard verification should come first: First, list qualifications, physical properties, and traceability as a checklist, then discuss price—standards are the protective talisman for procurement.
Make sample retention a habit: Keep samples for each batch and retest physical properties by batch. Compare batches and material changes before scaling up volume—stable batches, fewer customer complaints.
Adulteration, fluctuations, running away: compare with a single table
| Phenomenon | Cause | Countermeasures |
|---|
| Pitfalls | No standards | Establish standards |
| Data false | Untested | Report |
| Batch Chaos | No Traceability | Batch Locking |
| Price Inflated | No Comparison | Frequent Price Comparison |
| Customer Complaints | Poor Service | Supplier Swap |
Relying on Connections to Get Materials, Once Relationships Are Cut Off, Materials Are Cut Off — Procurement Relies on Data, Not on Relationships. Relationships and quotes look good, but when it comes to delivery, they can't be relied upon.
Avoid Procurement Pitfalls First: Physical Properties Straps Without Testing Conditions, Traceability Can Track Batches, Fast Prototyping Depends on R&D Reserves.
Elimination of missing items, prolonged elimination; only review samples from two companies; negotiate with another one to the end.
Qualification, Data, Batch, Production Capacity, and Reputation Five Essentials. Licenses, physical properties, and traceability are all included; missing any one means elimination, keep two or three before reviewing samples.
Suppliers are long-term partners, not one-time deals. Priority given to those who respond quickly and can adjust processes; those who only sell materials without following the machine should bear the consequences themselves. Service must be included in the evaluation.
Pass each of the 8 standards one by one, small batch trial production yield meets the standard, and suppliers filter out the two most reliable suppliers from a pile of quotes. Don't just slap your head when talking about data; relationships can't be considered acceptance.
Eight standards screen suppliers: license, physical properties, traceability, response, sample retention, mixing rate, color powder management, after-sales. Eliminate missing items, only identify samples when two remain, don't negotiate with one to the end.
Relationship quotes look good, but when delivery comes, you can't rely on
. All three companies are on the same caliber for inquiries, record response speed and problem depth. If you can't get the operating condition in just three sentences, lower priority; if you only sell materials but don't follow the machine, handle the problem yourself.
Priority for those who respond quickly and can adjust the process; if problems arise only for selling materials but not following the machine, take responsibility yourself. No material property traceability in license is missed; service terms are written in the evaluation form, and no other company negotiates to the end.
Relationship quotations look good but are unreliable at delivery. Elimination of missing items and delayed elimination; only two companies need to recognize; another company will negotiate to the end, and no matter the license physical property traceability, nothing will be missed.
Eight standard screening suppliers will eliminate missing items, leaving only two companies to identify samples and negotiate with another company to the end.
. License physical property traceability, response, sample retention, mixing rate, color powder management, after-sales service, none missing; those who respond quickly and adjust processes are prioritized; only selling materials without following the machine will bear the consequences themselves.
Cologne customer case: tight delivery deadline with performance matched, readjusting formula to supplement certification
a modified material application factory in Nanjing, tight delivery time, in-stock grades and performance not matched. Kelon remixed formulas (oil/additives/filling ratios), aligned performance, passed third-party testing and completed certifications. Formula readjustment, delivery time was reclaimed from the source—if performance didn't match, first look at the formula system.
Summary
TPE Avoid pitfalls in raw material procurement: set standards first, verify data, lay out eight sieves, and standards are the sieve
