Complete Guide: How to Calculate Import Duty and Taxes in Nigeria (2026 Update)

Imagine this: You've just paid ₦3.2 million for goods from China. The container arrives at Apapa port, and your clearing agent calls to tell you your customs bill is ₦1.8 million.

Crazy, right? But this happens every day. Importers budget for products and shipping, and then customs charges come and destroy their profit margins.

The formula isn't secret. Customs uses the same calculation every time. Most importers just don't know it.

Here's exactly how to calculate import duty in Nigeria before you ship, so you can budget the right amount for your imports, every time you order from China.

The Quick Formula You Need For Your Next Import

Save this for the next time you import goods from China

CIF = Cost + Insurance (0.5% of C+F) + Freight

Import Duty = Duty Rate % × CIF

Surcharge = 7% × Import Duty

CISS = 1% × FOB in ₦

ETLS = 0.5% × CIF in ₦ (non-ECOWAS)

Subtotal = CIF + Duty + Surcharge + CISS + ETLS

VAT = 7.5% × Subtotal

Total Duty = Duty + Surcharge + CISS + ETLS + VAT

Where Importers Go Wrong

As you calculate customs costs, make sure to avoid these common mistakes

1. Using black market exchange rates: Customs uses CBN official rate (₦1,470/$). Not parallel market. Not yesterday's rate. The official CBN rate on clearance day.

2. Ignoring VAT: VAT is 7.5% on top of your total. Not on product cost. On CIF + all duties combined. It can be a massive extra cost if you calculate it wrongly.

3. Guessing the HS code: Don’t say "It's a phone accessory, so probably 20%." Make sure you confirm. Wrong code = wrong rate = extra thousands paid.

4. Forgetting insurance in CIF: Insurance is tiny (0.5%) but required. Skip it and your CIF will be wrong from the start.

• What You're Actually Paying For

When your goods arrive at Nigerian ports, you pay five separate charges:

1. Import Duty (the main tax)

2. Surcharge (7% of your duty)

3. CISS (inspection fee)

4. ETLS (ECOWAS levy for non-ECOWAS imports)

5. VAT (7.5% on top of everything)

The key is knowing how to calculate each one. Let's take a look at the terms that matter

How Proc360 Eliminates Customs Surprises

Everything starts with CIF. If you get this wrong, then every subsequent calculation fails.

Let's try a real life example: Amaka's Shoe Import

Amaka imports women's shoes from China. Here's her breakdown:

Order details:

• Product cost: $8,000

• China handling fees: $600

• Shipping to Lagos: $2,000

• HS Code: 6403.99 (women's leather shoes)

• Duty rate: 20%

Watch how the numbers build up:

Product cost: $8000

Freight: $2000

Insurance: 0.5% × ($8,000 + $2,000) = $50

CIF: ($8,000 + $2,000 + $50) = $10,050

Now, convert that to naira at $1=₦1,470

Current CIF cost is ₦14,773,500

Customs Charges

Import Duty: 20% × ₦14,773,500 = ₦2,954,700

Surcharge: 7% × ₦2,954,700 = ₦206,829

CISS: 1% × ₦12,642,000 = ₦126,420

ETLS: 0.5% × ₦14,773,500 = ₦73,868

Total cost (without taxes)= ₦18,135,317

VAT: 7.5% × ₦18,135,317 = ₦1,360,149

Final Landed Cost: ₦19,495,466

Her $8,000 order costs ₦19.5 million landed.

Customs added ₦4.7 million. That’s almost 32% of the CIF value.

That's why you need to calculate before ordering, and this guide will show you exactly how much you’ll pay for customs clearance.

• Your Product's HS Code Determines Everything

Different products have different duty rates. For example

How to find your HS code:

• Nigeria Customs Tariff book

• Ask your supplier

• Nigeria Customs Service website

• Clearing agent

Wrong HS code = wrong duty rate = surprise bills at the port.

Platforms like Proc360 sort goods by the correct HS codes upfront to prevent custom clearance issues at the port.

• Duty Rates Differ by Product Type

Goods can be divided into three broad categories:

1. Low duty (5-10%): Raw materials, industrial machinery, medical equipment

2. Medium duty (20-25%): Electronics, textiles, shoes, cosmetics

3. High duty (35-70%): Vehicles, rice, alcohol, tobacco

We also have prohibited goods like used clothing, counterfeits, certain pharmaceuticals that have extra high duties to prevent their importation
