Compliance Gap Matrix

Gap matrix
Compliance item Common China baseline Tanzania (TBS / EWURA / TANESCO) Gap / action Source + verification date
China GB/T Baseline vs Tanzania Market Entry Package A typical China-origin file set may include GB/T 37408-2019, GB/T 19964-2024, NB/T 32004, IEC CB reports, CQC/CGC voluntary certificates, Chinese EMC reports, Chinese labels/manuals, and China utility settings sheets. GB/T 37408-2019 remains the current baseline located in public searches, while a 2025 GFM revision item has been reported but should be tracked until formally issued. This is a useful starting point but not a Tanzania approval package.GB/T 37408-2019
GB/T 19964-2024

IEC CB Scheme reports
CQC / CGC voluntary certificates		 A Tanzania market-entry package for a grid-tied PV inverter normally combines TBS PVoC shipment conformity where the consignment is regulated, accepted IEC 62109 or equivalent model safety evidence, TBS/TZS standards checks where applicable, EWURA licensing or registration for the electricity activity where in scope, and TANESCO or network-operator interconnection acceptance for the actual project.TBS PVoC import conformity
IEC 62109-1 and IEC 62109-2 or accepted equivalent safety evidence
EWURA electricity licensing or registration
Electricity (Grid and Distribution Codes) Rules, 2017
TANESCO or relevant network-operator project interconnection acceptance		 The export gap is procedural, documentary, and project-specific as much as technical. Build a Tanzania crosswalk, confirm PVoC and compulsory-standard scope before shipment, map safety evidence to IEC 62109 or accepted TZS requirements, prepare English labels and manuals, and plan EWURA/TANESCO documentation for the project configuration.[INFORMATIONAL] Do not treat a China GB/T file as a Tanzania approval file. Tanzania needs a PVoC, IEC/TZS, EWURA, and TANESCO-specific package where each gate is in scope. State Administration for Market Regulation / Standardization Administration of China2026-06-14 · unverified
EWURA Electricity Activity Licensing or Registration China project approvals, grid-connection filings, or distributed-PV registration documents do not transfer to EWURA. They can help explain project design and inverter capability but cannot replace Tanzania activity licensing or registration.China distributed PV project filing procedures
State Grid or China Southern Power Grid project acceptance documents
Local China project approval records		 EWURA states that electricity generation, transmission, distribution, supply, system operation, electricity trade, and electrical installation activities require a licence unless exempted, and that activities above 1 MW are licensed while activities below 1 MW are registered. EWURA's current public licensing page still points applicants to an online licensing route and references LOIS; any March-2026 move to an EWURA e-Service portal should be checked on the live application portal before filing. A PV inverter is not licensed as a standalone product, but the project using it may need EWURA licensing or registration before operation.Electricity Act, Cap 131
EWURA electricity licensing and registration requirements
EWURA online licensing / e-Service application portal, current route to be confirmed before filing
Electricity (Development of Small Power Projects) Rules where applicable		 The product file should be separated from the project approval file. For grid-connected or commercial PV projects, the Tanzania developer should confirm EWURA licence, registration, exemption, and small-power-project route before relying on the inverter for operation.[INFORMATIONAL] Treat EWURA licensing or registration as a project gate. A compliant inverter import file does not by itself permit electricity activity. Energy and Water Utilities Regulatory Authority (EWURA)2026-06-14 · unverified
Grid and Distribution Codes; TANESCO Interconnection Acceptance China grid evidence under GB/T 19964, GB/T 37408, NB/T 32004, State Grid, or China Southern Power Grid procedures may support technical review but is not TANESCO interconnection acceptance. Tanzania settings, forms, and commissioning records must be produced for the actual project.GB/T 19964
GB/T 37408
NB/T 32004
State Grid / China Southern Power Grid interconnection procedures		 EWURA lists the Electricity (Grid and Distribution Codes) Rules, 2017 among Tanzania electricity regulatory tools. For a grid-tied PV inverter, the project must satisfy the applicable grid or distribution code, utility interconnection review, protection settings, anti-islanding behavior, metering, and commissioning evidence required by TANESCO or the relevant network operator.Electricity (Grid and Distribution Codes) Rules, 2017
TANESCO or relevant network-operator interconnection requirements
Project-specific protection, metering, and commissioning requirements		 The largest grid gap is usually firmware and evidence: voltage and frequency trip points, reconnection timing, anti-islanding, reactive-power behavior, export limiting, and commissioning records must match Tanzania project requirements rather than China default settings.[INFORMATIONAL] Treat Tanzania grid approval as a project workflow. Confirm TANESCO or network-operator settings before shipment and commissioning. Energy and Water Utilities Regulatory Authority (EWURA)2026-06-14 · unverified
50 Hz Grid Configuration and Local Firmware Profile China domestic inverter settings are also normally 50 Hz, so nominal frequency alone is not the gap. The gap is the accepted Tanzania protection profile, trip windows, reconnection timing, and evidence for the exact utility connection.GB/T 19964
GB/T 37408
NB/T 32004
China utility settings sheets		 Tanzania grid-connected PV inverters should be configured for the local AC system and the protection profile required by the applicable grid or distribution code and the network operator. The 50 Hz operating profile, frequency ride-through or trip thresholds, voltage windows, reconnection delay, and anti-islanding settings should be documented for the Tanzania project.Electricity (Grid and Distribution Codes) Rules, 2017
TANESCO or relevant network-operator protection settings
Project commissioning and settings record		 Do not assume that a China 50 Hz profile is acceptable. Exporters should provide a Tanzania settings sheet, locked or controlled firmware profile where required, and commissioning evidence showing the configured frequency and voltage protections.[INFORMATIONAL] 50 Hz compatibility is necessary but not sufficient. Confirm the Tanzania protection profile and commissioning evidence for the actual site. Energy and Water Utilities Regulatory Authority (EWURA)2026-06-14 · unverified
TBS PVoC Import Certificate of Conformity China factory certificates, domestic test reports, CCC-exemption notes, CQC or CGC voluntary certificates, and Chinese customs files can support the PVoC document review but do not replace a Tanzania PVoC Certificate of Conformity when the HS code and product are in scope.China factory inspection records
CQC / CGC voluntary inverter certificates where available
China export customs documentation		 Tanzania Bureau of Standards states that PVoC verifies selected imported goods against applicable national standards before shipment, and consignments subject to PVoC must obtain mandatory customs-clearance documents and a Certificate of Conformity before shipment. For a PV inverter shipment, the importer or exporter should check the current TBS regulated HS-code list and the appointed PVoC service provider route before loading.Tanzania Standards Act No. 2 of 2009, section 4(1)(s)
TBS Pre-shipment Verification of Conformity (PVoC) procedure
TBS regulated HS codes under the PVoC programme		 The key gap is procedural: a technically compliant China-origin inverter may still face rejection, fines, destination inspection, re-export, or delay if the Tanzania PVoC file and CoC are not completed before shipment for a regulated consignment.[INFORMATIONAL] Treat PVoC as a shipment gate, not only a technical test file. Confirm HS-code scope and obtain the Tanzania CoC route before loading. Tanzania Bureau of Standards (TBS)2026-06-14 · unverified
Tanzania Standards Catalogue and Compulsory-vs-Voluntary Status China GB/T and NB/T standards are useful for engineering comparison but are not Tanzania standards. If a TZS or adopted IEC standard is compulsory for the import route, the China report should be crosswalked clause by clause and accepted by the PVoC provider or local reviewer.GB/T 37408
GB/T 19964
NB/T 32004		 TBS describes its standards catalogue as containing bibliographic information on Tanzania standards, including voluntary and compulsory standards across electrical engineering, energy, conformity assessment, and related fields. For PV inverters, the applicable TZS or adopted IEC references should be checked against the current catalogue and any compulsory or gazetted standard lists rather than assumed from an IEC or China report alone.TBS Standards Catalogue
TBS compulsory standards list where applicable
TBS gazetted standards list where applicable		 Do not label every IEC or TZS reference as mandatory. The mandatory status depends on TBS compulsory or gazetted lists, PVoC HS-code scope, project specifications, and grid-connection requirements.[INFORMATIONAL] Confirm mandatory status from TBS lists and the PVoC route. A standard reference alone does not prove market-access approval. Tanzania Bureau of Standards (TBS)2026-06-14 · unverified
PV Inverter Safety Evidence — IEC 62109-1 and IEC 62109-2 China-origin inverter files may include IEC CB Scheme reports, GB/T 37408 performance evidence, NB/T 32004 technical evidence, or CQC/CGC voluntary certificates. These can support acceptance but should be checked against IEC 62109 clauses and the exact Tanzania PVoC or project requirement.IEC CB Scheme reports
GB/T 37408
NB/T 32004
CQC / CGC voluntary certificates		 For Tanzania import review, project procurement, and technical due diligence, PV inverter safety evidence is commonly mapped to IEC 62109-1 for general power-converter safety and IEC 62109-2 for particular inverter requirements where those standards, adopted TZS versions, or equivalent accepted standards are requested. The evidence should be model-specific and tied to the exact hardware, firmware, ratings, and installation instructions shipped.IEC 62109-1, Safety of power converters for use in photovoltaic power systems - Part 1: General requirements
IEC 62109-2, Safety of power converters for use in photovoltaic power systems - Part 2: Particular requirements for inverters
Tanzania adopted TZS or accepted equivalent standards where applicable		 The gap is usually traceability and scope: the Tanzania file should show the same model, firmware, AC/DC ratings, isolation architecture, environmental rating, and installation limits as the shipped product, not only a generic family certificate.[INFORMATIONAL] IEC 62109 evidence is a strong safety baseline, but it must match the Tanzania import or project route and the exact shipped model. International Electrotechnical Commission (IEC)2026-06-14 · unverified
Factory Test Reports vs Tanzania Import Acceptance Chinese factory routine test records, internal quality control reports, and domestic certification files are useful inputs. They should be organized into a PVoC-ready file and reconciled with any IEC 62109, TZS, labeling, and shipment-document requirements.Factory routine test records
ISO 9001 quality records where available
China domestic certification or voluntary certificate files		 TBS PVoC allows conformity assessment through a combination of inspection, laboratory testing, documentary review, and factory audits where necessary. A PV inverter supplier should prepare test reports, quality documents, labels, manuals, serial-number controls, and shipment documents in a format accepted by the appointed PVoC provider.TBS PVoC certification procedure
TBS appointed PVoC service provider instructions
Applicable TZS, IEC, or accepted equivalent standards for the product		 A China factory file may be technically strong but incomplete for Tanzania if it lacks shipment traceability, accepted test-lab evidence, correct model naming, English documentation, or PVoC provider forms.[INFORMATIONAL] Build the China factory file into a PVoC-ready shipment file before export; technical reports alone may not clear the consignment.
