Import duty on construction materials in Kenya

Import duty on construction materials in Kenya sits at the centre of almost every cost overrun on a building project that relies on imported steel, tiles, glass, sanitary ware or specialised machinery.

Kenya builds fast, but it does not build entirely from local inputs. Nairobi’s glass towers rely on toughened glass panels shipped in from the Gulf and Asia. Mid-range apartment finishes lean on porcelain tiles from India and China. Structural steel projects import high tensile sections that local mills cannot roll. Every one of these materials crosses a Kenyan port, and every one of them is taxed before it reaches a construction site. Contractors and quantity surveyors who ignore this step at the tendering stage routinely watch a well-priced bill of quantities collapse once the actual customs assessment lands. Anyone pricing a project that leans on concrete grade contractor rates in Kenya or imported finishes needs the duty picture settled first, not as an afterthought.

This guide works through the East African Community Common External Tariff (EAC CET), the charges the Kenya Revenue Authority (KRA) layers on top of it, and the specific duty treatment of the materials that actually move through Mombasa port and the Nairobi Inland Container Depot on a typical building project.

What Is Import Duty on Construction Materials in Kenya?

Import duty on construction materials in Kenya is a tax charged at the point of entry on cement inputs, steel, tiles, glass, aluminium products, sanitary fittings and machinery brought into the country from outside the East African Community. It is charged under the East African Community Customs Management Act and assessed using the EAC Common External Tariff, which since 2022 runs on a four band structure of a minimum duty rate of 0%, rates of 10% and 25%, and a maximum rate of 35%, with certain sensitive goods facing rates above this ceiling. The duty is one part of a wider tax stack that also includes the Import Declaration Fee, the Railway Development Levy and VAT, all of which combine to form the true landed cost of an imported building material.

What Is the EAC Common External Tariff?

The EAC CET is the shared tariff schedule used by all six East African Community partner states. As one detailed breakdown puts it, the EAC CET is a unified tariff system used by Kenya, Uganda, Tanzania, Rwanda, Burundi, and South Sudan, and it simplifies cross-border trade within the region while protecting local industries through graduated tariff bands. A material’s position in that schedule, identified by an eight digit HS code under Kenya’s national tariff extension, is what ultimately determines how much duty a contractor pays.

What Is the Difference Between Import Duty, IDF, RDL and VAT?

Import duty is a percentage charged on the customs value of the goods based on the EAC CET band. The Import Declaration Fee (IDF) is a separate customs processing charge, reduced from 3.5% to 2.5% of CIF value under the Finance Act 2023, with a minimum floor of KES 5,000 per consignment. The Railway Development Levy (RDL) funds the Standard Gauge Railway and is charged as a percentage of CIF value on top of duty. VAT, at 16%, is then applied to the sum of the CIF value and the duty already paid, meaning VAT is effectively charged on a duty-inclusive figure rather than the bare import price.

Why Does Kenya Tax Imported Construction Materials?

Kenya’s tariff policy on construction materials reflects a deliberate industrial strategy rather than a blanket revenue grab. Materials that Kenyan factories already produce in volume, such as ordinary cement and basic reinforcement bars, tend to sit in higher duty bands to protect domestic manufacturers such as those clustered around the Kenya Association of Manufacturers membership. Materials Kenya cannot produce at scale, such as certain grades of structural glass, high specification lifts, and heavy plant, are more likely to sit in lower bands or qualify for remission, because taxing them heavily would simply raise the cost of every building project without protecting any local industry.

How Does This Protectionist Policy Affect Local Manufacturing?

The EAC Council of Ministers regularly reclassifies goods as “sensitive” to shield local producers. Recent EAC gazette changes illustrate this directly: the FY 2026/2027 measures reinforce the EAC’s industrialization agenda by combining higher tariffs on selected finished goods with duty relief for manufacturing inputs, strategic projects and priority sectors. For construction materials specifically, this has translated into ceramic tiles being pushed toward the top of the tariff scale while raw material inputs used by Kenyan tile, cement and steel manufacturers are kept closer to 0% or 10% to support local production. Contractors sourcing locally through verified suppliers of quality building materials in Kenya can often avoid this tariff exposure entirely.

Import Duty Rates for Specific Construction Materials in Kenya

The table below sets out how the major categories of imported construction material are typically treated under the EAC CET. Because HS codes within a single material category can carry different rates depending on finish, thickness or intended use, these figures are indicative bands rather than a substitute for a formal classification ruling from KRA or a licensed clearing agent.

Indicative bands under the EAC Common External Tariff 2022, as amended by subsequent EAC Gazette notices. Confirm the exact HS code and current rate with a licensed clearing agent or directly at kra.go.ke before committing to a landed cost budget.

How Is Cement Taxed at the Kenyan Border?

Cement itself is manufactured domestically in significant volume by Kenyan producers, so finished bagged cement is rarely imported at scale and, where it is, typically sits toward the upper duty band to protect local output. Clinker, the semi-finished raw material Kenyan cement factories grind into finished product, is treated differently and often benefits from lower duty because it is an industrial input rather than a finished consumer good. This is a clear example of the EAC’s layered approach: the rate comes from the EAC Common External Tariff, which has four bands, 0% for most raw materials and capital goods, 10% for intermediate goods, 25% for finished goods, and a 35% band added in 2022 for many sensitive finished products.

How Is Structural Steel Classified for Duty Purposes?

Steel is one of the most heavily disaggregated categories in the tariff schedule. A single steel shipment can contain multiple HS codes at different rates depending on whether the product is a raw billet, a hot rolled bar, a cold rolled sheet, or a fabricated fastener. As one classification reference confirms for a common narrow-strip steel product, Kenya extends classifications to 8 digits under its national tariff system, and 721129 belongs to Chapter 72, Iron and steel, under the flat rolled products heading. Contractors importing structural steel sections should insist their clearing agent classify each line item separately rather than applying a single blanket rate across an entire consignment, since misclassification is a common cause of post-clearance audits and penalties.

Why Do Ceramic Tiles Attract Some of the Highest Rates?

Kenya has a growing domestic tile manufacturing base, and recent tariff amendments have pushed imported ceramic tiles toward the top of the scale specifically to protect that industry. A regional tax summary notes that under recent EAC gazette changes, the duty on certain items has been increased to 35%, including ceramic tiles, adjusted from varying previous rates. This is one of the clearest examples of industrial policy shaping a building material’s landed cost, and it is a major reason developers sourcing finishes should compare imported tile pricing carefully against locally manufactured alternatives before specifying a finish schedule.

How Are Construction Machinery and Heavy Equipment Taxed?

Heavy plant such as excavators, wheel loaders and concrete pumps is priced differently from finished building materials because Kenya does not manufacture this equipment domestically. As one specialist import guide explains, Kenya Revenue Authority classifies most construction machinery under HS Chapter 84, applying an import duty of 25% on the customs value for excavators, wheel loaders, and bulldozers, although certain crawler mounted excavator codes can attract a reduced rate depending on the specific classification confirmed with a clearing agent. VAT at 16% is then charged on top of the dutiable value, meaning a machine landing at a customs value of roughly USD 26,000 can carry close to USD 13,000 in combined duty and VAT before port handling fees are even added.

How Total Landed Cost Is Calculated on Imported Construction Materials

Understanding the duty rate alone is not enough to budget accurately. The full landed cost stacks four separate charges on top of the invoice price, and each is calculated slightly differently.

As one practical cost breakdown summarises the stacking order, IDF is the Import Declaration Fee, a customs processing fee of 2.5% of the customs CIF value, subject to a minimum of KES 5,000, and duty is only the first layer, excise where applicable, IDF, RDL and VAT are added on top. Quantity surveyors preparing a bill of quantities for an import-heavy project should always model this full stack rather than the headline duty rate alone, since the combined effect of RDL, IDF and VAT typically adds twenty percentage points or more onto the base duty figure.

Worked Example: Landed Cost of Imported Ceramic Tiles

Take a consignment of porcelain floor tiles with a CIF value of KES 2,000,000, classified at the 35% duty band. Import duty comes to KES 700,000. The Import Declaration Fee at 2.5% of CIF adds KES 50,000. The Railway Development Levy at 2% of CIF adds KES 40,000. VAT at 16% is then charged on the CIF value plus duty, which is KES 2,700,000, giving KES 432,000. Before port handling and clearing agent fees, the total tax burden on this single shipment reaches KES 1,222,000, effectively 61% on top of the original CIF value. This is precisely why developers frequently reconsider imported finishes once actual landed cost figures replace supplier quotations at the tender stage.

Exemptions, Remissions and Relief Programmes

Not every imported construction material is taxed at the standard rate. Kenya maintains several legal pathways to reduce or eliminate duty on specific categories of building materials, though each requires formal application and approval rather than automatic entitlement.

Public Private Partnership Infrastructure Projects

Materials imported for qualifying infrastructure projects can be exempted entirely from duty. A recent tax alert confirms that the stay of EAC CET application on goods imported for the direct and exclusive use in the implementation of infrastructure projects undertaken under a Public Private Partnership framework is conditional on approval by the Cabinet Secretary for the National Treasury on the recommendation of the Cabinet Secretary for the Ministry responsible for the implementation of the project. This exemption is project-specific and requires a formal application well before materials are shipped.

Duty Remission for Local Manufacturers

Kenyan manufacturers who process imported raw materials into finished building products domestically, such as steel mills importing billets to roll into bars, can apply for duty remission on those inputs. As one guide notes plainly, if machinery is imported for manufacturing in Kenya, you may qualify for duty remission, reducing your import costs significantly. This remission does not extend to contractors importing finished materials directly for a single project; it is reserved for registered manufacturers.

LPG and Energy Infrastructure Exemptions

Recent tariff amendments extended IDF exemptions to a narrow category of energy infrastructure. According to a current tax summary, there is an exemption from IDF for goods imported for the construction of liquefied petroleum gas storage tanks and related infrastructure, subject to a minimum investment value of KES 5 billion upon the recommendation of the Cabinet Secretary responsible for energy. This illustrates how narrowly targeted these exemptions tend to be, generally reserved for large, strategically significant projects rather than routine commercial construction.

Verifying Whether a Material Qualifies for Relief

Because exemption categories change with each Finance Act and EAC Gazette notice, contractors should never assume a material qualifies for relief based on an old article or a previous project. The safest approach is to confirm current status directly through a licensed clearing agent or the Kenya Revenue Authority before finalising a procurement plan, and to build the standard duty rate into the base budget so any approved exemption becomes a saving rather than a rescue.

Compliance Steps for Importing Construction Materials Into Kenya

Getting the tariff classification right is only part of the process. KRA and other regulatory bodies require a defined documentation sequence before any consignment is released at the port.

Common Mistakes That Inflate Import Duty Costs on Construction Projects

Misclassifying Materials Under the Wrong HS Code

A wrong HS code can trigger either an underpayment penalty and back duty demand, or an overpayment that quietly erodes project margin. Steel products in particular carry multiple codes within a single shipment, and treating an entire consignment under one blanket code is a frequent, costly error.

Failing to Budget for the Full Tax Stack

Pricing a project against the headline duty rate alone, without adding IDF, RDL and VAT, consistently understates landed cost by twenty to thirty percent. Every import-heavy bill of quantities should model the full stack from the outset.

Assuming Exemptions Apply Without Formal Approval

Exemptions for PPP infrastructure projects or energy infrastructure require explicit Treasury or ministerial approval before shipment. Assuming eligibility without that approval on file is a common cause of unexpected assessment at the port.

Ignoring Currency and Valuation Risk

Because duty is calculated on CIF value converted to Kenya shillings, exchange rate movement between order placement and customs clearance can materially change the final tax bill on large consignments, particularly for steel and machinery priced in US dollars.

Sourcing Locally Versus Importing: A Cost Comparison Framework

Before committing to an imported material, it is worth running a simple comparison: local price plus any local supply risk, against landed import cost plus lead time risk. For categories such as ceramic tiles, where duty can reach 35% before VAT is even applied, locally manufactured alternatives frequently outcompete imports once the full tax stack is included, even where the raw import price looked cheaper on a supplier quotation. For categories such as structural glass or specialised lifts, where Kenya has limited domestic manufacturing capacity, importing usually remains the only realistic option regardless of duty, making accurate landed cost budgeting even more important. Reviewing current labour rates for construction workers in Kenya by region alongside material costs gives a fuller picture of where local sourcing genuinely saves money on a project.
