Testing personnel of the factory laboratory are responsible for issuing the original records and draft the testing report with the designated laboratory engineers according to the prescribed form. The testing report is issued by the relevant designated laboratory upon examination and approval.



0.2 Requirements for Manufacturers Classification Management



CQC collects and arranges information related to certified product and its manufacturer quality for dynamic classification management on the manufacturers with the assistance of certification client, producer and manufacturer.



CQC classifies the manufacturers into four classes which are expressed as A, B, C and D respectively.



The quality information on which manufacturer classification is based contains at least the following information:



(1) Result of factory inspection (including initial factory inspection and follow-up inspection after certification);



(2) Testing results of sample testing and/or supervisory sampling (including type test, production site sampling or market sampling) and sample authenticity;



(3) Testing results of national or provincial random inspection, special CCC random inspection, etc.;



(4) Coordination of certification client, producer and manufacturer for post-certification supervision;



(5) Judicial decision, complaint arbitration, media exposure, consumer quality information feedback, etc.;



(6) Quality of certified product;



(7) Other information.



See Table 1 for manufacturer classification principle.



 

Table 1 Manufacturer Classification Principle

Category Classification principle

A Category B enterprises provide conformity data to CQC which conducts integrated risk assessment on the collected quality information and data provided by the enterprise and determines the category. The assessment shall at least cover the following information:

1. Production conditions: complete production line (rubber mixing-vulcanizing) (including equipment and capacity of producer or group company);

2. Factory inspection: no non-conformance items affecting the product consistency upon initial factory inspections/follow-up inspections after certification in the last two years (including the current year).

3. Results of product inspection and random inspection: no non-conformance item upon post-certification supervision and testing in the last two years (including the current year); the conclusion of all national and provincial inspections and CQC special inspections is "qualified".

4. Product testing capacity: the manufacturer (or its producer and parent company) shall possess testing capacity required by certification standards. (Conforming to technical capability requirements specified in Chapter 5 of GB/T 27025 (IEC 17025))

5. Products imported into China within supervision period shall reach a certain quantity.

6. Other information related to the quality of the certified product and its manufacturer.

B Other manufacturers except those of Classes A, C and D.

The manufacturer without any quality information is classified into Class B by default.

C Those that meet one of the following conditions are classified into Class C enterprises:

1. Where the conclusion judgment is "site verification" upon initial factory inspection and post-certification follow-up inspection;

2. Where quality problems exist and are caused by the enterprises but not serious enough to suspend or revoke the certificate;

3. Where CQC adjusts the enterprises into Class C as per the results of comprehensive evaluation on quality information related to the manufacturers and their certified products.

D Those that meet one of the following conditions are classified into Class D enterprises:

1. Where conclusion of factory inspection is judged as "rejected" and the certified product has quality problems;

2. Where the result of the supervision sampling testing is “rejected” and the product safety performance is affected;

3. Where inspections and/or supervision sampling are rejected without justifiable reasons;

4. Where serious quality problems exist as revealed by the media and are caused by the enterprise;

5. Where the conclusions of national and provincial and CCC special inspection are "rejected" and the safety performance of the product is affected (with the exception of nonconformity of instruction/identification);

6.Where CQC adjusts the enterprises into Class D as per the results of comprehensive evaluation on quality information related to the manufacturers and their certified products.



CQC will determine the classification result (class) of manufacturers according to the above classification principles based on various quality information acquired in real time.



CQC reclassifies the manufacturers periodically or aperiodically according to various information so as to realize dynamic management. If there is any change, public documents of CQC shall prevail. In principle, the manufacturer level shall be upgraded according to D-C-B-A or degraded from A-B-C-D or adjusted to the level required after the risk assessment.

检查人日数根据生产企业（场所）、检查内容和所委托认证产品的单元及覆盖的产品规格数量确定，并适当考虑生产企业的规模，一般为4～6人日/加工场所。
7.2.4 检查结论
初始工厂检查未发现不符合项或有轻微不符合项且现场已完成整改并经检查组确认有效的，工厂检查结果评价为合格。
初始工厂检查存在不符合项，可允许限期（不超过３个月）整改。生产企业应采取纠正措施，并将整改材料报CQC。
CQC 采取适当方式对整改结果进行确认(对整改情况进行书面验证或现场验证)。整改有效，工厂检查结果为合格；逾期未完成整改或整改结果不满足要求的，工厂检查结果为不合格，终止本次检查，终止认证。
工厂检查发现生产一致性控制文件的执行情况与申报并经CQC 确认的生产一致性控制文件存在严重偏差，或实际生产产品与型式试验合格样品或经确认的产品描述存在重大差异时，检查结果不合格，终止本次检查。
7.3 认证结果评价与批准
认证机构对型式试验、初始工厂检查的结论和有关资料/信息进行综合评价，对符合认证要求的，评价通过，按单元颁发认证证书。
当型式试验不合格、初始工厂检查不通过，CQC 做出不合格决定，终止认证。终止认证后认证委托人如要继续委托认证，应重新提出认证委托。
7.4认证时限
自受理认证委托之日起至颁发认证证书时止不超过90 天，包括型式试验时间、初始工厂检查时间及检查后提交报告时间（适用时）、认证结果评价和批准时间，以及证书制作时间。
以上认证活动完成时间，不包括不符合整改时间及复试检测时间。对不符合认证要求的情况，CQC 应书面通知委托人，并说明理由。
本细则没有做出明确规定的认证流程及时限，以CQC 有关程序文件及作业指导书要求为准。CQC 将按照相关程序文件和作业指导书的要求控制认证时限完成相关工作，认证委托人、生产者、生产企业应予以配合。
认证委托人、生产者（制造商）、生产企业对认证实施工作应予以积极配合和协助。由于认证委托人、生产者、生产企业其自身原因逾期未完成认证活动导致认证超时，不计入认证时间内。
8 获证后监督
认证委托人、生产者（制造商）、生产企业应按《强制性产品认证管理规定》、《强制性产品认证标志管理办法》、《强制性产品认证证书注销、暂停、撤销实施规则》、《强制性产品认证实施规则中涉及ODM 模式的补充规定》、实施规则、本实施细则和认证标准的要求，确保其持续生产的获证产品符合法律法规和标准要求、企业质量保证能力和产品一致性控制持续符合认证要求。
认证委托人、生产者（制造商）、生产企业应在本实施细则第8.1 条规定的周期内接受监督，否则按不能接受获证后监督处置。对于非连续生产的产品，认证委托人、生产者（制造商）、生产企业应主动向CQC 提交生产计划，以便于后续跟踪检查的有效开展。
8.1 获证后监督方式选择
获证后的监督方式包括获证后跟踪检查、生产现场抽取样品检测/检查或市场抽样检测/检查；结合生产企业分类结果和实际情况，获证后监督为其中一种或多种方式的组合。
获证后监督方式的选择见表3。

8.2 获证后跟踪检查的要求
8.2.1 获证后的跟踪检查原则
CQC 在生产企业分类管理的基础上，对获证产品及其生产企业实施有效的跟踪检查，以验证生产企业的生产一致性控制持续符合认证要求、确保获证产品持续符合标准要求并保持与获得批准的产品的一致性。
获证后的跟踪检查应在生产企业正常生产时，优先选择不预先通知被检查方的方式进行。对于非连续生产的产品，认证委托人应向CQC 提交相关生产计划，便于获证后跟踪检查的有效开展。
8.2.2 获证后的跟踪检查内容
跟踪检查至少包括以下内容：
(1) 生产一致性控制计划的实际执行情况，包括生产者或生产企业按照实施规则附件3 完成的生产一致性控制计划执行报告；
(2) 认证产品的结构及参数（包括型号规格和关键零部件）与《机动车辆轮胎产品技术参数表》的一致性和认证产品现场指定试验（从工厂提交的生产一致性文件计划中规定的项目中选取）；
(3)认证标志和认证证书的使用情况；
(4)前次工厂检查不符合项、外部质量信息中有关认证产品不合格的纠正、纠正措施及其有效性的验证。
8.3生产现场抽样检测或者检查
8.3.1 抽样地点
由CQC 指定人员在工厂生产线、仓库或口岸（仅限境外获证工厂）等地，按本细则8.3.2 的规定抽取样品，抽取的样品应是经生产者或生产企业确认的合格品。认证委托人、生产者或生产企业应在CQC 抽样后10 个工作日内寄出样品。
8.3.2 抽样规格和数量
CQC 根据生产企业分类结果（类别），确定监督抽样的产品规格和数量，原则上按表4 执行，应优先抽取以往未抽取过的获证产品。
