货到海关被扣，理由只有一条：认证不齐。REACH/ROHS提前备，不然货出不去。
货到海关被扣，认证没提前备
TPE 出口认证是“合规活”：REACH、ROHS、报关。结论先给：REACH/ROHS不齐卡海关——认证，是出口的通行证。
TPE出口认证最大的坑：REACH SVHC和ROHS缺一项，货到港直接被扣——认证，是出口的底线。
出口是合规关：认证齐，出口顺。认证缺，卡海关——出口，是采购的合规题。
出口是合规门槛，为什么先备单证
REACH 是欧盟门槛：化学品注册。REACH，是出口的硬门槛。
ROHS 是限用门槛：有害物质限制。ROHS，是出口的硬标准。
海关查证：单证齐全放行。海关，是出口的关卡。
认证、检测、单证，备什么
认证：对应目的国要求。认证，是头一项。
检测：第三方报告。检测，是第二项。
单证：报关资料齐。单证，是第三项。
认证要求，一张表对照清楚
| 市场 | 认证 | 检测 | 判断 |
|---|
| 欧盟 | REACH | 有 | 必备 |
| 欧盟 | ROHS | 有 | 必备 |
| 美国 | FDA | 有 | 按需 |
| 国内 | 无 | 常规 | 达标 |
表格读法：市场不同要求不同，欧盟REACH、美加州Prop65分开列。
认证，是出口的通行证。
单证齐货能出，准备核这四项
| 项目 | 要求 | 判断 |
|---|
| REACH | 齐 | 达标 |
| ROHS | 齐 | 达标 |
| 报告 | 可查 | 达标 |
| 单证 | 齐全 | 达标 |
表格读法：认证一项项核，出口看得见，报告有效期和测试机构标上。
认证，是出口的底线。
认证不齐报告过期，货卡在港
坑一：认证不齐。货到了才发现SVHC没更新，清关卡住——认证必齐。
坑二：报告过期。白备——报告必新。
坑三：单证缺项。卡关——单证必全。
REACH、ROHS、有效期——出货前备
三问：什么市场、什么认证、什么单证。一验：报告核验实测——三问一验，供应商底细清楚。
认证验证要先行：先把REACH SVHC清单、ROHS、目标市场认证备齐，再谈发货——认证，是出口的通行证。
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。
卡关、报告过期、补证：对照一张表
| 现象 | 原因 | 对策 |
|---|
| 卡关 | 认证缺 | 提前备 |
| 白备 | 报告过期 | 更新 |
| 扣货 | 单证缺 | 补单证 |
| 延误 | 没预案 | 做预案 |
| 客诉 | 合规松 | 走流程 |
货卡海关，多半是认证没前置，不是货有问题。REACH、RoHS 要的是报告对得上批次。
按目标市场列清单：欧盟 REACH/RoHS、美国 FDA/LFGB。报告编号、日期、机构三项先备齐。
认证报告对批次有效，过期就重测。软胶料配方一调，报告就要更新，别拿两年前的报告走新单。
等货到港才发现缺一份报告，柜压在港口每天都在烧钱。认证周期比生产还长，必须前置。
合规清单+报关演练跑在前，整批一次放行。出口单不再因为一张纸延误。

小结
TPE出口认证的准备，认证先备，报告再核，REACH和ROHS缺项就卡港，认证是通行证。
The goods were held up at customs for only one reason: incomplete certification. Prepare REACH/ROHS in advance, otherwise the goods cannot be shipped out.
The goods were held by customs, certification was not prepared in advance
TPE export certification is 'compliance in action': REACH, ROHS, customs declaration. Here's the conclusion first: REACH/ROHS alone are not enough for customs—the certification is the passport for export.
The biggest pitfall in TPE export certification: missing either REACH SVHC or ROHS will result in the goods being directly detained at the port — certification is the bottom line for export.
Exporting depends on compliance: with all certifications, export goes smoothly. Without certifications, customs will hold it—export is a compliance issue for procurement.
Export is a compliance threshold, so why prepare documents first?
REACH is the EU threshold: chemical registration. REACH is a hard threshold for exports.
ROHS is a restriction threshold: restriction of hazardous substances. ROHS is a strict standard for export.
Customs verification: release if all documents are complete. Customs is the checkpoint for exports.
Certification, testing, documentation, what to prepare
Certification: According to the requirements of the destination country. Certification is the first item.
Testing: third-party report. Testing is the second item.
Documents: Customs declaration materials are complete. Documents are the third item.
Certification requirements, one form to clearly compare
| market | Certification | Detection | Judgment |
|---|
| European Union | REACH | have | Essential |
| European Union | ROHS | have | Essential |
| United States | FDA | have | On demand |
| domestic | None | Regular | Meet the standard |
Table reading: Different markets have different requirements, with the EU REACH and California Prop65 listed separately.
Certification is the passport for exports.
The goods can be shipped once the documents are complete; prepare to check these four items.
| Project | Requirement | Judgment |
|---|
| REACH | Qi | Meet the standard |
| ROHS | Qi | Meet the standard |
| Report | Verifiable | Meet the standard |
| Documents | Complete | Meet the standard |
Table reading: Verify each certification item one by one, check the export visibility, and mark the report validity period and testing organization.
Certification is the baseline for export.
Certification incomplete and report expired, goods stuck at the port
Pitfall 1: Incomplete certifications. You only realize the SVHC hasn't been updated after the goods arrive, causing customs clearance to be stuck — all certifications must be complete.
Pitfall 2: Report expired. Always prepare in advance—the report must be up-to-date.
Pitfall Three: Missing documents. Checkpoint — all documents must be complete.
REACH, ROHS, Validity Period — Prepare Before Shipment
Three questions: what market, what certification, what documents. One verification: report verification and actual measurement — three questions and one verification, the supplier's details are clear.
Certification and verification should come first: first gather the REACH SVHC list, ROHS, and target market certifications, then discuss shipment—certification is the passport for export.
Making sample retention a habit: retain samples for each batch, and re-test physical properties batch by batch. Before switching materials between batches, compare them first before scaling up—the batch is stable, and customer complaints are few.
Stuck, expired reports, supplementary certificates: check against a single table
| Phenomenon | Reason | Countermeasure |
|---|
| Stuck at a level | Certification missing | Prepare in advance |
| completely prepared | Report expired | Update |
| Withhold goods | Missing documents | Supplement documents |
| Delay | No plan | Make a contingency plan |
| Customer complaint | Compliance relaxation | Follow procedures |
Customs for cargo trucks is mostly due to the certification not being prepared in advance, not because there is a problem with the goods. REACH and RoHS require the reports to match the batch.
List according to target market: EU REACH/RoHS, US FDA/LFGB. Prepare the three items first: report number, date, and organization.
The certification report is valid for the batch; once it expires, it must be retested. Once the soft gel formula is adjusted, the report needs to be updated. Don't use a report from two years ago for a new order.
Only when the goods arrived at the port did we find that one report was missing, and the container sitting at the port was costing money every day. The certification cycle is longer than production, so it must be done in advance.
Compliance checklist: Customs declaration exercises are done in advance, allowing the entire batch to be released at once. Export orders will no longer be delayed because of a single document.
Most of the time, customs issues with cargo trucks are due to missing pre-approval, not problems with the goods. REACH and RoHS require that the reports match the batch, and the inventory should be listed according to the target market: EU REACH/RoHS, US FDA/LFGB. First, prepare the report numbers, dates, and issuing organizations.
If the certification report is valid for the batch and expires, it will be retested.
The soft rubber formula report needs to be updated as soon as it's adjusted. Don’t use a report from two years ago for a new order. The certification process is longer than production and must be done in advance. Waiting until the goods arrive at the port to find the report missing results in containers being held at the port and costs accumulating every day.
The export document compliance checklist should be completed before customs declaration practice. The entire batch will be released at once, no longer delayed because of a single piece of paper. The REACH SVHC list is updated every year, and newly added restricted substances need to be screened in the formulas in advance.
It wasn't until the goods arrived at the port that I discovered one report was missing, and the container is stuck at the port, costing money every day.
The certification period is longer than production, so it must be done in advance. Reports are valid for specific batches, and if expired, re-testing is required. Don’t use a report from two years ago for a new order.
Compliance checklist plus customs declaration drill run ahead, whole batch released at once
. Export documents no longer get delayed because of a single piece of paper. The REACH SVHC list is updated every year with new restricted substances, requiring the formula to be screened in advance, and only discovering the missing report when the goods arrive at the port results in containers sitting at the port and burning money every day.
Most issues with cargo trucks at customs are due to certification not being pre-approved, not because there is a problem with the goods. REACH and RoHS require that the report matches the batch. Make a list according to the target market, and first prepare the three items for the EU REACH/RoHS and US FDA/LFGB: report number, date, and institution.
Most of the problems with cargo trucks at customs are due to the lack of prior certification, not because there is an issue with the goods.
REACH/RoHS requires that the report matches the batch and lists the target market. EU REACH/RoHS, US FDA/LFGB—certification reports are only valid for the batch. Once the formula is adjusted, the report needs to be updated. Don’t use a report from two years ago for a new order.
The certification cycle is even longer than production, so you have to pre-order and only discover missing reports when the goods arrive at the port, causing daily losses due to storage at the port.
. REACH SVHC list is updated annually with newly restricted substances, allowing for early formulation screening. Whole batches can be released at once without being delayed by a single paper report.
Cologne Customer Case: Low-temperature cracking led to full batch scrapping, sample data shows 98% yield rate
A Wuhu-based modified material application factory experienced a batch of TPE export parts cracking at low temperatures, resulting in the entire batch being scrapped. Cologne assisted by providing samples and physical property data from the same batch, with batch pass rate consistently above 98%. With samples plus data, performing the low-temperature test once aligns everything — for cracking issues, first check the plasticizer and filler system.
Summary
Preparation for TPE export certification: prepare for certification first, verify reports afterward. Missing items in REACH and ROHS regulations will hold up shipments at the port; certification is the passport.
