Observater is Tanzania’s premier independent Third-Party Inspection & Survey (TPI) agency. Headquartered at the Port of Dar es Salaam with a major Operational Hub in Arusha & Mwanza, we deploy expert surveyors nationwide. We conduct Pre-Shipment Inspections and Surveys at the source—whether in the Lake Zone, Arusha’s agricultural belt, or the Southern Cashew corridor—before containers move via SGR or road to the port.
Sourcing from Tanzania offers immense opportunities in sectors such as Agricultural Commodities (Cashew Nuts, Coffee, Cotton, Spices), Mining (Gold, Gemstones), and Scrap Metal Recycling. However, sourcing remotely from East Africa poses significant risks that can impact your bottom line. Importers often face challenges such as shipping delays, quality fade after the first order, quantity shortages, improper packaging, and even fraudulent “ghost” suppliers who disappear after receiving a deposit.
Observater Tanzania eliminates these risks by acting as your neutral representative on the ground. We are locally rooted with a robust nationwide network, meaning we can be at any factory or farm within 48 hours. Our Tanzania Quality Control Inspections and Surveys are strictly governed by international standards and TBS (Tanzania Bureau of Standards) guidelines, ensuring every survey is legally defensible.
Whether you are importing Raw Cashew Nuts (RCN) from Mtwara, Arabica coffee from Arusha, textiles from Mwanza, or Scrap Metal from Dar es Salaam, our certified surveyors ensure your goods meet every specification before the container is sealed. We provide the transparency you need to trade with confidence.
We provide more than just a checklist. We provide comprehensive risk mitigation tailored to the Tanzanian market.
We perform deep background checks. We verify Certificates of Incorporation, TRA TINs (Tax Compliance), and valid Business Licenses with **BRELA** to ensure you are dealing with a legal entity.
We assess production reality. Our auditors visit factories in Dar es Salaam, Bagamoyo, and Mwanza to count machinery, check production lines, and verify daily output capacity.
Rigorous inspections to TBS standards and International ISO requirements. We verify product safety, functionality, and aesthetics before goods leave the port or warehouse.
Protect your brand. We conduct social audits ensuring compliance with Tanzanian Labor Laws, checking for child labor, forced labor, and safe working conditions.
A complete lifecycle of quality assurance, from initial supplier vetting to final container sealing. We offer a holistic approach to securing your supply chain.
Don’t send money to a ghost. We physically visit the factory to verify legal existence (BRELA), check production lines, interview management, and ensure the machinery matches the product description.
Identify risks before mass production starts. We inspect raw materials (raw cashew, cotton lint, ingredients) and prototypes against your specifications.
Inspection when 20-50% of goods are ready. We catch defects on the assembly line, allowing for immediate corrective action without delaying the final shipment date.
The industry standard. Final Random Inspection (FRI) of 100% produced goods to verify quality, quantity, labeling, and packing before shipment using AQL tables.
We witness the stuffing of the container at Dar es Salaam Port, Kwala Dry Port, or the supplier’s warehouse. We ensure the goods are handled correctly and sealed.
We draw random samples during inspection and submit them to ISO 17025 accredited labs for chemical, microbiological, or physical property testing.
The Pre-Shipment Inspection and Survey (PSI) is the critical quality firewall. It is the final opportunity to catch defects before your goods leave Tanzanian soil. 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. This ensures we see a true representation of the cargo without needing to open every single box.
Our 7-Point Survey Protocol:
Sourcing from a distance requires trust, but trust must be verified. Our Factory Audit services provide a transparent profile of your supplier. We travel to the facility—whether in Dar es Salaam, Mwanza, or rural areas—to confirm they are who they claim to be. We differentiate between real manufacturers/processors and trading companies.
Audit Scope:
We utilize the Acceptable Quality Limit (AQL) standard (ISO 2859-1) to determine the number of samples inspected. This ensures a statistically accurate representation of the total shipment quality without opening every single box, balancing cost and risk.
Defect Classification System:
We don’t use generic checklists. Every industry requires specific expertise. Our surveyors are trained specialists in their respective fields.
Inspecting at the Mtwara warehouses or Moshi Coffee Exchange. We check:
Verifying export consignments from the Lake Zone and Arusha. We check:
For ginneries in Mwanza and textile mills in Dar. We check:
Specialized survey for recyclable materials in Dar and Arusha. We check:
Tanzania is a key hub for the export of recyclable materials. We provide specialized supplier verification and preshipment inspections for scrap metal traders and recycling plants. Our surveyors oversee compaction checks, container stuffing, and final sealing to ensure compliance and security. Many scrap metal consignments, particularly UBC (Used Beverage Cans), are surveyed at yards in Dar es Salaam and Arusha before being trucked to the port.
From your initial booking to the final report, our process is streamlined, transparent, and fast.
You send us the supplier details and survey requirements.
Our Ops team in Dar contacts the supplier to arrange the inspection date.
Our surveyor visits the factory/warehouse, performs the check, and takes photos.
You receive a detailed PDF report with photos and a Pass/Fail result within 24 hours.
Beyond the factory floor, the final hurdle is export readiness. Our FPSI focuses on the logistics conformity of the consignment. We seal containers at the source in Arusha, Mwanza, or Dodoma to prevent tampering during the transit to Dar es Salaam.
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, Kwala Dry Port, or the supplier’s warehouse. We prevent bad stowage, theft, and damage.
We reject unfit containers. Our 7-point survey 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.
The final chain of custody. We witness the door closing and apply high-security bolt seals. We record seal numbers immediately.
Our multi-hub structure ensures we cover the entire supply chain lifecycle, from raw material sourcing in the interior to final export at the coast.
Arusha and Mwanza serve as our command centers for the North and Lake Zones. From these hubs, we deploy teams to coffee estates, cotton ginneries, and gold mines. This proximity allows us to monitor production and seal containers at the source before they transit to Dar.
Dar es Salaam is our Headquarters and the final gatekeeper. Our senior surveyors are stationed here to oversee Container Loading, Warehousing, and Port Discharge. We maintain strict control over the Port and Inland Container Depots (ICDs) to ensure what was produced is exactly what is shipped.
We don’t just inspect; we connect the dots. Our integrated approach ensures that quality is maintained from the moment raw materials are sourced until the container seal is locked in Dar es Salaam.
