Observater is Tanzania’s premier independent Third-Party Inspection (TPI) agency. Operating from Dar es Salaam with port presence in Tanga and Mtwara, we deploy expert surveyors nationwide to verify suppliers and inspect goods before shipment.
Sourcing from Tanzania offers incredible opportunities in Agricultural Commodities (Cashew Nuts, Cotton, Coffee, Sisal), Mining (Gold, Gemstones), and Manufacturing. However, sourcing remotely from East Africa poses significant risks: logistics delays, quality fade, quantity shortages, and verification of suppliers.
Observater Tanzania eliminates these risks. We are locally rooted with a comprehensive nationwide network. Our Tanzania Quality Control Inspections are strictly governed by ISO 2859-1 (AQL) standards. Whether you are importing Cashews from Mtwara, Cotton from Mwanza, Scrap Metal from Dar es Salaam, or Coffee from Arusha, our certified inspectors ensure your goods meet every specification before the container is sealed.
We verify Business Licenses, TIN Registration, and Export Permits with BRELA and the Tanzania Revenue Authority (TRA).
Assessment of factories in Dar es Salaam, Mwanza, and Arusha to confirm production output and machinery.
Inspections to TBS (Tanzania Bureau of Standards) requirements and ISO standards before goods leave the port.
Social audits ensuring compliance with Tanzanian Labor Laws and international human rights standards.
A complete lifecycle of quality assurance, from initial supplier vetting in Dar es Salaam to final container sealing at the port.
We visit the facility to verify legal existence (BRELA/TRA), production lines, and machinery to ensure they can meet your capacity.
Full Audit Details →Identify risks before mass production starts. We inspect raw materials (raw cashew nuts, cotton bales, components) against your specifications.
Inspection when 20-50% of goods are ready. We catch defects on the assembly line, allowing for immediate corrective action.
The industry standard. Final Random Inspection (FRI) of 100% produced goods to verify quality, quantity, and packing before shipment.
Methodology →We witness the stuffing of the container at Dar es Salaam Port, ICDs, or the supplier’s warehouse to ensure security and proper sealing.
We draw samples and submit them to ISO 17025 accredited labs (e.g., TBS Labs) for chemical and physical testing.
The Pre-Shipment Inspection (PSI) is the critical quality firewall. It is the final opportunity to catch defects before your goods leave Tanzania via Dar es Salaam or other ports. Observater’s PSI services are conducted strictly according to the international standard ISO 2859-1 (ANSI/ASQ Z1.4), determining the statistically valid sample size based on your total order volume.
Our 7-Point Inspection Protocol:
Sourcing from a distance requires trust, but trust must be verified. Our Factory Audit services provide a transparent, detailed profile of your supplier. We travel to the facility—whether in Dar es Salaam, Mwanza, or Arusha—to confirm they are who they claim to be.
Audit Scope:
We utilize the Acceptable Quality Limit (AQL) standard to determine the number of samples inspected and the threshold for acceptance or rejection. This ensures a statistically accurate representation of the total shipment quality without opening every single box.
Defect Classification System:
Tanzania is a global leader in Cashew Nut exports. We provide specialized inspection services for Raw Cashew Nuts (RCN) in Mtwara and Lindi, ensuring grading meets international standards (Outturn calculation). We also inspect Scrap Metal, Copper, and Minerals for export.
Beyond the factory floor, the final hurdle is export readiness. Our FPSI focuses on the logistics conformity of the consignment before it is handed over to the forwarder. We ensure your documentation matches the physical cargo to prevent customs delays at Dar es Salaam Port, ICDs, and Across Tanzania.
The most critical moment for cargo safety. We oversee the transfer of goods from the warehouse floor into the container at the Dar es Salaam Port, Tanga Port, or the exporter’s facility. We prevent bad stowage, theft, and damage before the journey.
We reject unfit containers before loading begins. Our 7-point inspection checks for holes, odors, wet floors, and defective locking gear.
Maximizing space while ensuring safety. We supervise stacking patterns to prevent crushing and verify lashing/dunnage to stop movement.
The final chain of custody. We witness the door closing and apply high-security bolt seals. We record seal numbers immediately.
Our structure ensures we cover the entire supply chain lifecycle, from raw material sourcing in the interior to final export at the port.
Dar es Salaam is our headquarters and command center. From here, we coordinate Factory Audits and Port Operations. We have rapid access to major industrial areas like Pugu, Mikocheni, and the port zones.
We operate at the source. Our surveyors in Mtwara cover the Cashew trade. Teams in Mwanza handle Cotton and Lake Zone logistics. Arusha is our base for Coffee and Gemstone inspections.
We don’t just inspect; we connect the dots. Our integrated approach ensures that quality is maintained from the moment raw materials enter the warehouse until the container seal is locked.
Verifying inputs at farms or mines in the interior.
Monitoring processing (e.g., cashew shelling) and sorting.
AQL statistical checks on finished, packed goods.
Final supervision and sealing at Dar/Mtwara Port.
Specialized grading for Cashews (Mtwara), Coffee (Arusha), and Sisal (Tanga).
