A Commercial Invoice is one of the most important documents in international trade. Whether you are exporting goods by sea, air, road, or rail, the information shown on the commercial invoice can directly affect customs clearance, import duties, shipment processing, and communication between the seller and buyer.

A small mistake — such as an incorrect product description, quantity, value, or Incoterm—can create questions during customs clearance and potentially delay a shipment.

For businesses involved in international shipping, understanding how to prepare a commercial invoice correctly is therefore essential.

1. What Is a Commercial Invoice?

A commercial invoice is a document issued by the seller or exporter to the buyer or importer for goods sold internationally.

It provides the commercial details of the transaction, including what is being sold, the quantity, value, currency, buyer and seller information, and other shipping-related information.

Unlike a simple domestic sales invoice, a commercial invoice is commonly used as part of the documentation required for international shipping and customs procedures.

Customs authorities may use the document to understand:

• What goods are being imported or exported

• Who is buying and selling the goods

• The declared commercial value

• The origin of the goods

• The terms of sale

• The basis for calculating applicable duties and taxes

The exact requirements can vary depending on the destination country, type of cargo, and customs regulations.

2. Why Is a Commercial Invoice Important in International Shipping?

The commercial invoice performs several important functions throughout an international shipment.

Customs clearance

Customs authorities review the invoice to identify the goods, transaction value, country of origin, and other information relevant to import or export procedures.

If information is incomplete or inconsistent, customs may request clarification or additional documentation.

Customs valuation

The declared value on the commercial invoice may be one of the key pieces of information considered when determining the customs value of imported goods.

This can affect the calculation of duties, VAT, or other import-related charges.

Buyer and seller record

The invoice also serves as a commercial record between the exporter and importer, showing the goods sold and their agreed value.

Freight and logistics documentation

Freight forwarders and customs brokers may refer to information from the commercial invoice when preparing shipment documents, customs declarations, and transportation instructions.

For this reason, consistency between documents is extremely important.

3. What Information Should a Commercial Invoice Include?

Although requirements differ between countries, a typical commercial invoice should contain the following information.

Seller / Exporter Information

Include the full legal details of the company selling the goods:

- Company name
- Address
- Country
- Telephone / Email
- Tax or business identification number, when applicable

Buyer / Importer Information

Provide the full details of the receiving company:

- Buyer / Importer name
- Address
- Country
- Contact information

If the importer of record is different from the buyer, additional information may be required.

Invoice Number

Each commercial invoice should have a unique reference number.

For example:

Invoice No.: VICO-EXP-2026-001

A clear numbering system makes documentation easier to track and reconcile.

Invoice Date

State the date the invoice was issued.

Product Description

The description should be clear enough for customs authorities to understand what the product actually is.

Instead of:

- Parts

use a more specific description such as:

Stainless steel machine components for industrial equipment

Instead of:

- Clothes

use:

Men's 100% cotton knitted T-shirts

Specific descriptions generally reduce ambiguity during customs review.

Quantity

Include the number of units being sold.

For example:

500 cartons

or

10,000 pieces

The quantity should match related shipping documents.

Unit Price

State the agreed price for each unit.

Example:

USD 5.00 / piece

Total Commercial Value

Calculate the total value of the goods.

For example:

10,000 pieces × USD 5.00

Total Value: USD 50,000

Currency

Always clearly identify the currency.

Examples include:

- USD
- EUR
- CNY
- VND

Writing only “50,000” without stating the currency can create unnecessary confusion.

HS Code

Where appropriate, include the relevant Harmonized System (HS) code used to classify the product for customs purposes.

Correct classification is important because the HS code can influence duties, restrictions, documentation requirements, and customs procedures.

Country of Origin

The country of origin identifies where the goods were manufactured or produced.

For example:

Country of Origin: Vietnam

The country of origin is not necessarily the same as the country from which the goods are shipped.

Incoterms

Clearly state the agreed Incoterm and named place.

For example:

FOB Hai Phong Port, Incoterms® 2020

or:

DDP Shanghai, Incoterms® 2020

This helps clarify how transportation costs, responsibilities, and risks are allocated between the seller and buyer.

Shipping Information

Depending on the shipment, the invoice may also include:

Mode of transport, port of loading, port of discharge, final destination, shipment reference or purchase order number.

Payment Terms

Examples include:

- T/T 30 days

- 100% payment before shipment

- Letter of Credit

- Payment terms should reflect the actual commercial agreement between seller and buyer.

4. How to Prepare a Commercial Invoice Step by Step

A practical process can reduce documentation errors.

Step 1 — Confirm seller and buyer information

Use the correct legal company names and addresses.

Avoid abbreviations unless they are officially part of the company's registered name.

Step 2 — Confirm the purchase order

Compare the invoice against the purchase order or sales contract.

Verify:

- Product
- Quantity
- Price
- Currency
- Payment terms
- Incoterm

Step 3 — Describe the goods accurately

Use clear commercial descriptions rather than internal product codes alone.

For example, an invoice showing only:

Model XZ-102

does not explain what the product actually is.

A better description might be:

Electric motor, Model XZ-102, 220V, for industrial machinery

Step 4 — Check quantity, unit price, and total value

Make sure the calculation is correct.

Quantity × Unit Price = Total Value

Also verify whether freight, insurance, or other costs need to be shown separately based on the transaction and destination requirements.

Step 5 — Confirm HS codes and origin

Incorrect HS classifications or origin information can create customs problems.

If classification is uncertain, businesses should confirm it with an experienced customs professional rather than guessing.

Step 6 — State the Incoterm correctly

Don't write only:

FOB

Instead, specify the named location:

FOB Cat Lai Port, Incoterms® 2020

The named place is an important part of the Incoterm.

Step 7 — Cross-check all shipping documents

Before submitting the documentation, compare the Commercial Invoice against:

- Packing List
- Bill of Lading / Air Waybill
- Certificate of Origin
- Customs Declaration
- Purchase Order

Important information such as quantity, cargo description, weight, consignee, and shipment details should be consistent where applicable.

5. Commercial Invoice Example

A simple commercial invoice could look like this:

COMMERCIAL INVOICE

Exporter:
ABC Coffee Export Co., Ltd.
Ho Chi Minh City, Vietnam

Importer:
XYZ Trading Co., Ltd.
Shanghai, China

Invoice No.: ABC-2026-018

Invoice Date: September 18, 2026

Product: Vietnamese roasted coffee beans, 1kg commercial bags

HS Code: [Applicable HS Code]

Quantity: 2,000 bags

Unit Price: USD 8.00

Total Value: USD 16,000

Country of Origin: Vietnam

Incoterm: CIF Shanghai, Incoterms® 2020

Currency: USD

Payment Terms: T/T

This is only a simplified example. Actual customs and documentation requirements may differ by market and commodity.

6. Commercial Invoice vs. Proforma Invoice

A Commercial Invoice and Proforma Invoice can contain similar information, but they serve different purposes.

A Proforma Invoice is generally issued before the final sale or shipment. It may be used to provide the buyer with an estimated price and transaction details.

A Commercial Invoice represents the actual commercial transaction and is commonly used during the shipment and customs clearance process.

In simple terms:

Proforma Invoice → before the final transaction

Commercial Invoice → actual shipment / commercial transaction

Businesses should not automatically substitute one for the other when customs requires a final commercial invoice.

7. Commercial Invoice vs. Packing List

These documents are related but serve different functions.

The Commercial Invoice focuses primarily on the commercial value and transaction.

It contains information such as:

- Product value
- Unit price
- Currency
- Buyer and seller
- Payment terms
- Incoterms

The Packing List focuses mainly on the physical shipment.

It typically contains:

- Number of cartons
- Package dimensions
- Net weight
- Gross weight
- Packing method
- Marks and numbers

A simple way to remember the difference is:

Commercial Invoice = What the goods are worth

Packing List = How the goods are physically packed

Both documents should describe the same shipment consistently.

8. Common Commercial Invoice Mistakes

Documentation errors can lead to additional questions, corrections, customs delays, and unexpected costs.

Some of the most common problems include:

Vague product descriptions

Writing “samples,” “parts,” or “accessories” may not provide enough information.

Incorrect HS codes

Incorrect product classification can affect customs duties and regulatory requirements.

Invoice value does not match the transaction

The declared commercial value should reflect the transaction and comply with applicable customs rules.

Incorrect currency

Always state whether the transaction is in USD, EUR, CNY, or another currency.

Inconsistent quantities

The number of units on the Commercial Invoice should correspond with the relevant shipping and packing documents.

Incorrect Incoterms

For example, the sales contract may state FOB while the invoice states CIF.

Incorrect country of origin

Shipping goods from Vietnam does not automatically mean the goods originate in Vietnam.

Documents do not match

Commercial Invoice, Packing List, B/L, AWB, C/O and customs declarations should not contain conflicting shipment information.

9. Commercial Invoice Checklist Before Shipping

Before sending the invoice to your logistics or customs team, check:

✓ Exporter information correct
✓ Importer information correct
✓ Invoice number and date included
✓ Product descriptions clear
✓ Quantity correct
✓ Unit prices correct
✓ Total invoice value correct
✓ Currency stated
✓ HS code checked
✓ Country of origin checked
✓ Incoterm + named place included
✓ Payment terms correct
✓ Information matches Packing List
✓ Information matches transportation documents
✓ Any destination-specific requirements confirmed

Taking a few minutes to perform this check can prevent significantly more time being lost later in the shipment.
