Tanzania Certificate of Conformity (PVoC) Pre-Export Verification of Conformity (PVoC) is a program to ensure that products imported into the country comply with the applicable technical regulations. The certificate of conformity resulting from the positive assessment must be provided during customs procedures.

Consignments of goods subject to mandatory regulation may be subject to one of three possible assessment schemes, depending on the frequency of shipments and the type of exporter.

Scheme A: This is a scheme available to all goods, regardless of whether the exporter is a producer or trader. This scheme requires the inspection and testing of consignments by an authorized inspector.

Scheme B: This is a scheme that includes an annual record of renewed products and the issuance of a certificate of conformity per consignment of products (including surveillance and random testing by a designated inspector).

Scheme C: This is a scheme suitable for manufacturers who have successfully implemented a quality management system in their production cycle. Includes product licensing and certification of conformity per product shipment (including random surveillance but without testing as in Scheme B)
