How to calculate import tax in Oman

Goods imported into Oman can attract up to three charges: customs duty, excise tax (for specific products) and import VAT. They are calculated in sequence, each on a base that includes the charges before it. This guide shows the method, a worked example and the exemptions that commonly apply.

The three charges at a glance

Goods of GCC origin that meet the GCC customs union's rules of origin generally move between member states without customs duty. Some goods carry higher protective or specific duties, and a limited list is exempt.

Step 1: Work out the CIF value

Customs duty in Oman is charged on the CIF value, meaning the price of the goods plus the cost of insurance and freight to the Omani port of entry.

CIF = cost of goods + insurance + freight

If the supplier quotes FOB (free on board), add the shipping and insurance costs. Customs will rely on the commercial invoice, the bill of lading or air waybill, and the insurance documents. If declared values look low, customs can reassess them using the GCC valuation rules.

Step 2: Apply the customs duty rate

Find the HS code for your product in the GCC Common Customs Tariff. Most goods are dutiable at 5% of CIF. Examples of exceptions:

• Exempt or 0%: many basic foodstuffs, certain medicines and medical equipment, and inputs covered by industrial exemptions
• Higher rates: tobacco products and some goods protected under GCC rules
• Prohibited or restricted goods: these need prior approval or cannot be imported at all

Customs duty = CIF × duty rate

Step 3: Add excise tax where it applies

Oman's excise tax applies to a defined list of goods:

Importers of excise goods must be registered for excise tax with the Oman Tax Authority. Excise is due when the goods are released from customs.

Step 4: Calculate import VAT

VAT at 5% is charged on imports at the point of entry:

Import VAT = (CIF + customs duty + excise tax) × 5%

VAT-registered businesses can usually account for import VAT through their VAT return under the reverse-charge mechanism and recover it as input tax, so it does not become a cash cost. Unregistered importers pay it at clearance. See VAT registration in Oman.

Worked example

A trading company imports electronics with a supplier price of OMR 10,000, freight of OMR 600 and insurance of OMR 100.

On top of this come clearance costs: customs broker fees, port and handling charges, and any inspection or storage charges.

Exemptions worth checking

• GCC-origin goods with valid certificates of origin
• Free zone imports: goods brought into a free zone are generally duty-free while they stay there. See free zones in Oman.
• Industrial exemptions for registered factories on machinery and raw materials. See the industrial licence.
• Temporary imports of equipment for projects or exhibitions, against a guarantee
• Returned goods re-imported in the same condition

Paying and clearing

Declarations are lodged electronically through the customs system, usually by a licensed customs broker using your company's importer registration. Duties and VAT are paid before release. For the full procedure, read how to obtain customs clearance in Oman.

Frequently asked questions

What is the customs duty rate in Oman?

Most goods pay 5% of the CIF value under the GCC Common Customs Tariff. Some goods are exempt, and a few carry higher rates.

Is VAT charged on imports in Oman?

Yes. Import VAT at 5% is charged on the CIF value plus customs duty and any excise tax. VAT-registered businesses can usually recover it.

Do I pay customs duty on goods from the UAE or Saudi Arabia?

Goods that qualify as GCC origin generally move duty-free within the GCC customs union. Goods originating outside the GCC that were already cleared in another GCC state follow the customs union's transit and duty-transfer rules.

Who pays import tax, the buyer or the seller?

The importer of record pays, usually the Omani buyer. Under DDP (delivered duty paid) terms, the seller arranges and bears it.
