Tanzania Verification of Conformity (PVOC)

Tanzania Pre-Export Verification of Conformity (PVOC) is a mandatory certification scheme implemented by the Tanzanian government to ensure imported products comply with relevant standards and safeguard consumer safety, the environment and public health, which is regulated by the Tanzania Bureau of Standards (TBS). All products covered in the controlled list must obtain a Certificate of Conformity (COC) via PVOC certification prior to export to Tanzania; otherwise, the goods will be detained, fined or returned during customs clearance.

Validity Period: Tanzanian PVOC certificate is issued for one shipment only, valid solely for the current batch of exported goods and cannot be reused.

Mandatory Requirement: As stipulated by TBS, Tanzanian Customs reserves the right to refuse entry of goods within the controlled list without a valid COC certificate. Therefore, certification must be completed before shipment.

Scope of Application

Tanzania PVOC certification covers a wide range of products, mainly including but not limited to the following categories:

Electrical and electronic products (such as household appliances, lighting fixtures, wires, cables and batteries);
Machinery and equipment (such as construction machinery, agricultural machinery and generators);
Construction materials (such as steel, cement, ceramic tiles, pipes and coatings);
Chemical products (such as plastic products, cleaning agents and cosmetics);
Textiles, garments, footwear and leather goods;
Toys, children's products and food contact materials;
Automobiles, auto parts and tires;
Furniture, paper products, etc.

Note: Special products such as food, pharmaceuticals and medical devices are subject to separate regulatory requirements. Please confirm with TBS in advance whether they fall under PVOC control.

Notes

Test Report Requirements: The test report must cover all key indicators specified in Tanzanian standards to prevent document review rejection due to incomplete test items.
Marking Compliance: Products shall be clearly marked with country of origin, model number, safety marks and other information; otherwise the on-site inspection may be failed.
Selection of Certification Bodies: Applications must be processed via third-party organizations authorized by TBS. Certificates issued by unauthorized bodies are invalid, so the qualification of the agency shall be confirmed in advance.
Time Arrangement: The PVOC certification process (including document review and inspection) normally takes 1 to 2 weeks, excluding product testing time. Advance preparation is recommended to avoid shipment delays.

Relevant Standards

Tanzanian Standards (TZS);
International standards mutually recognized by Tanzania (such as ISO, IEC, EN, BS, etc.);
National standards or industrial standards of exporting countries recognized by TBS (equivalence to TZS standards shall be verified).

Service Process

1. Submit Application

Fully completed application form (including product name, model, quantity, HS code, importer information, etc.);
Product manual, technical specification sheet, circuit diagram (for electrical and electronic products);
Clear photos of products (showing key information such as brand, model, compliance marks, country of origin);
Valid test report (issued by an ISO/IEC 17025 accredited laboratory, covering key product indicators, generally valid for 1-2 years);
Proforma invoice or commercial invoice, packing list;
Business license or registration certificate of the importer in Tanzania (if available).

2. Document Review

The certification body shall review the submitted documents, focusing on verifying whether the test report meets Tanzanian standard requirements, whether the technical documents are complete, and whether the product information is consistent. If the documents are incomplete or non-compliant, supplementary materials or rectification shall be carried out (such as retesting and revising technical parameters).

3. On-site Inspection (Mandatory)

All controlled products are subject to pre-shipment on-site inspection. Inspectors assigned by the certification body will verify the following items:

Consistency between goods and test samples (brand, model, specification, appearance, etc.);
Compliance of product marking (e.g. marking country of origin "Made in China", safety warnings, marks required by TBS, etc.);
Intact packaging and availability of necessary manuals (English is normally required).

4. Issue COC Certificate

After document review and on-site inspection are passed, the certification body will issue the Certificate of Conformity (COC), the final document for PVOC certification, within 3-5 working days. All information on the certificate must be completely consistent with customs clearance documents (invoice, bill of lading), otherwise customs clearance will be affected.
