List of TBS Certified Companies in Tanzania 2026: How to Search and Verify Certified Products

If you are searching for a list of TBS certified companies in Tanzania 2026, the most reliable source is the official Tanzania Bureau of Standards (TBS) certified-companies database.

TBS maintains an online register showing certified companies together with information such as:

• Company name
• Product name
• Brand name
• Licence number
• Location
• Applicable Tanzania Standard
• Certification issue date
• Certification expiry date

The list changes as new licences are issued, renewed or expire. Therefore, businesses, consumers, procurement officers and researchers should verify a company directly through the live TBS database instead of relying only on an old PDF or copied list.

Quick Answer: Where Can I Find TBS Certified Companies in Tanzania?

Use the official TBS certified-companies register:

TBS Certified Companies:
https://www.tbs.go.tz/companies

The register allows users to identify certified manufacturers and products and inspect the relevant certification dates and standards.

Important: TBS certification is generally connected to a particular product and standard. A company appearing in the register does not automatically mean that every product manufactured or sold by that company carries the same certification.

What Does TBS Certified Mean?

TBS operates several certification schemes, including:

• Standards Mark of Quality Certification
• Batch Certification
• Tested Product Certification
• Systems Certification

Under the Standards Mark Certification Scheme, manufacturers whose products conform to relevant Tanzania standards may be licensed to use the TBS Standards Mark of Quality.

TBS explains that products displaying its Standards Mark are independently and routinely tested against the applicable Tanzania standards and that permission to use the mark is granted to manufacturers meeting the required quality-auditing procedures.

Sample List of TBS Certified Companies in Tanzania 2026

The following are examples appearing in the official TBS certified-companies database during 2026.

This is not the complete national register because the official TBS database contains many more company-product certification records and is continuously updated.

These entries are examples from the official live register and should be rechecked before procurement, tender evaluation or commercial verification because expiry and renewal dates can change.

More TBS Certified Companies Appearing in the 2026 Register

Other examples appearing in TBS records include:

• Shafa Agro Limited
• Mannaeh Spices and Food Products Tanzania
• Darsh Industries Limited
• Global Drinking Water Ltd

The certification is attached to the listed product, standard and licence record—not merely to the company name.

How to Search the TBS Certified Companies List

The easiest approach is to use the company register and search by the information you know.

Search by company name

For example:

Tanga Cement

or:

Darsh Industries

This helps confirm whether a named manufacturer appears in the current register.

Search by product

Try product categories such as:

• Bottled water
• Cement
• Maize flour
• Mattress
• Soap
• Steel
• Cable
• Bread
• Cooking oil
• Cosmetics
• Roofing sheets

This is particularly useful for procurement officers looking for manufacturers of a particular product.

Search by brand

A company name may be unfamiliar while its brand is well known.

For example, the official register can show the:

• Manufacturer
• Product
• Brand
• Licence
• Standard

This makes brand-level verification easier.

Why You Should Check the Expiry Date

One of the most important fields in the TBS register is the certification expiry date.

A company may have been certified previously, but that does not automatically prove that the same certification remains valid today.

Check:

Issued Date

and

Expiry Date

For example, the register contains licences issued during 2025 that remain valid into 2026, as well as licences issued during 2026 that extend into 2027.

This distinction matters when using the information for:

• Government tenders
• Supplier verification
• Procurement
• Product sourcing
• Quality assurance
• Retail stocking
• Academic research

TBS Certification and Government Tenders in Tanzania

TBS certification may become particularly important when a public tender requires products to comply with specified national or international standards.

A tender could specify:

• TBS certification
• Tanzania Standard number
• Product-quality requirements
• Manufacturer authorisation
• Test certificate
• Other conformity documentation

The tender document determines exactly what bidders must provide.

Therefore, procurement teams should not merely ask:

Is this company TBS certified?

Instead, ask:

Is the specific product being offered certified against the standard required by this tender, and is the certification still valid?

This is a stronger procurement-control question.

Businesses searching public procurement opportunities can also monitor:

How to Verify a TBS Mark Before Buying

If you are buying goods for a company, institution or government contract, use a simple verification process.

Step 1: Check the manufacturer

Find the official company name.

Step 2: Identify the exact product

Do not verify only the brand.

Step 3: Search TBS

Use the official certified-company register.

Step 4: Compare the standard

Check the standard number displayed in the register.

Step 5: Check the licence

Where provided, compare the licence number.

Step 6: Confirm validity dates

Pay special attention to the expiry date.

Step 7: Investigate inconsistencies

If the product packaging and official database do not match, seek clarification from TBS or the manufacturer.

Can I Download the Full TBS Certified Companies List as PDF?

Users commonly search:

TBS certified companies Tanzania PDF

TBS certified products Tanzania PDF

list of TBS certified companies PDF

However, the online TBS register is more useful for current verification because certification records are continuously updated.

A static PDF can become outdated when licences:

• Expire
• Are renewed
• Change
• Are added
• Are removed

For current 2026 verification, use:

TBS Certified Companies

rather than depending only on an old downloaded list.

How Manufacturers Obtain the TBS Standards Mark

TBS explains that the Standards Mark Certification Scheme is available to manufacturers whose products conform to relevant Tanzania standards.

The mark indicates that product samples have been independently and routinely tested and certified against applicable standards. TBS grants permission to use the mark to manufacturers satisfying its certification and quality-audit procedures.

Manufacturers seeking certification should therefore use official TBS guidance rather than purchasing supposed “TBS certificates” from intermediaries.

TBS Certification Information

Be Careful With Fake TBS Certification Claims

A product label can be copied.

A logo can be printed.

A document can be altered.

Therefore, do not verify certification solely because a supplier sends you:

• A certificate image
• A WhatsApp photograph
• A company profile
• A quotation displaying the TBS logo

Cross-check the information in the official TBS system.

Be especially careful when purchasing:

• Food
• Drinking water
• Construction materials
• Electrical equipment
• Personal-care products
• Industrial products

TBS Certified Companies for Procurement Officers

Procurement professionals can create a supplier-verification table such as:

This can support supplier due diligence.

However, TBS certification alone does not determine whether a company is eligible for a tender.

Other requirements may include:

• Business registration
• Tax compliance
• Relevant licence
• Experience
• Financial capacity
• Manufacturer authorisation
• Tender-specific documentation
