+ Surveillance is conducted through the testing of samples for each import shipment.
– Method 5: Testing of typical samples and assessment of the production process; surveillance through testing of samples taken at the production site or on the market in combination with assessment of the production process.
The validity of the Certificate of Conformity shall not exceed 3 years and annual surveillance is conducted through testing of samples at the production site or on the market in combination with assessment of the production process.
This method is applicable to products manufactured by domestic or foreign production facilities that have established and maintained a quality management system to ensure stable product and goods quality.
– Method 7: Testing and assessment of product and goods batches.
The validity of the Certificate of Conformity is only valid for the batch of manufactured or imported building material products and goods.
3.2. Regulations on declaration of conformity
3.2.1. Domestically produced building material products and goods must be declared as conforming at the local Inspection Agency where the business is registered, based on the Certification results from a registered or recognized Certification Body in accordance with the law.
3.2.2. The dossiers, order and procedures for declaration of conformity shall comply with the provisions in Articles 14 and 15 of Circular No. 28/2012/TT-BKHCN, amended and supplemented in Circular No. 02/2017/TT-BKHCN and Circular No. 06/2020/TT-BKHCN (Applying the latest version when replaced or amended).
3.3. Regulations for imported building material goods
3.3.1. For imported building material goods specified in Part 2 of this Regulation, the importer must:
a) Register for state inspection of imported goods quality at the local Inspection Agency where the products or goods are imported.
b) When registering for state inspection, the name of the Conformity Certification Body and the Testing Organization that will perform the testing and quality certification assessment of the imported goods must be specified on the Registration Form No. 01 – Decree No. 74/2018/ND-CP dated May 15, 2018 of the Government, amended and supplemented according to Clause 9, Article 4 of Decree No. 154/2018/ND-CP dated November 9, 2018 of the Government. The Inspection Agency shall confirm that the importer has registered for inspection of imported goods quality on the registration form.
c) The importer shall submit the registration form confirmed by the Inspection Agency to the Customs Authority to be allowed to clear the goods.
d) Within 15 working days (for cement, cement additives, concrete and mortar products, it is 35 working days) from the date of customs clearance of the goods, the importer must submit a copy (signed and stamped by the importer) of the Certificate of Conformity and the results of goods quality inspection (performed by the conformity certification body and testing organization named in the registration form previously submitted to the Inspection Agency) in accordance with Table 1 of this Regulation to the Inspection Agency.
đ)In case the goods have been assessed by the Certification Body in the exporting country, within 03 working days from the date of customs clearance, the importer must submit a copy (signed and stamped by the importer) of the Certificate of Conformity to the Inspection Agency.
e) In case the importer registers for quality inspection on the National Single Window Portal, the registration for inspection and return of quality inspection results shall be done through the National Single Window Portal.
g) The importer shall be fully responsible before the law for the quality of the goods they import.
3.3.2. Application of exemption or reduction of quality inspection for imported building material goods in accordance with Clause 3, Article 1 of Decree 74/2018/ND-CP and Clause 3, Article 4 of Decree 154/2018/ND-CP dated 09/11/2018 of the Government amending, supplementing and repealing some provisions on investment and business conditions in the field of state management of the Ministry of Science and Technology and some regulations on specialized inspection.
When requesting exemption or reduction of inspection, the importing unit shall prepare 01 set of application dossier for exemption of inspection as prescribed in Clause 3, Article 4 of Decree 154/2018/ND-CP and send it to the local Inspection Agency for consideration and confirmation of exemption or reduction.
During the period of exemption or reduction of imported goods quality inspection: the importing unit shall comply with the provisions in Article 7, Circular No. 06/2020/TT-BKHCN dated 10/12/2020.
3.4. Regulations on handling of import dossiers and quality of imported building material goods that do not conform to technical regulations: implemented according to Clause 3, Article 6 and Article 9 of Circular No. 06/2020/TT-BKHCN dated 10/12/2020.
3.5. Methods of sampling, specifications and quantity of samples for testing and assessment
3.5.1. The method of sampling typical samples and representative samples shall comply with the provisions in the current national standards on sampling methods and sample preparation for the corresponding products.
