If you sell online and ship outside Turkey, you have probably run into the term commercial invoice for international shipping more than once. This single document decides whether your parcel clears customs smoothly or sits in a warehouse for days while the buyer asks where their order is. This guide explains what the document is, what belongs on it, and how to prepare it correctly every time.
What Is a Commercial Invoice for International Shipping?
A commercial invoice is a legal document that describes the goods inside a shipment, their value, and the parties involved in the sale. Customs authorities in the destination country use it to decide how much duty and tax to charge, and to verify that the shipment is legitimate. Unlike a regular sales receipt, it is written specifically for cross-border movement of goods and is required for almost every commercial shipment leaving Turkey, whether it travels by air, courier or postal service.
It is different from a proforma invoice, which is sent before the sale is finalized to give the buyer an estimate. The commercial invoice is the final version, issued once the goods are actually being shipped.
Why Customs Officers Rely on This Document
Think of the commercial invoice as the passport of your package. Without accurate information, a customs officer cannot classify the goods, apply the correct tariff, or confirm that nothing prohibited is inside the box. Missing or vague descriptions are one of the most common reasons shipments get held, returned, or charged extra fees. A clear, complete invoice speeds up clearance and reduces the chance of your buyer receiving an unexpected bill or a long delay.
What Information Should Be on a Commercial Invoice
While formats vary slightly by carrier, a complete commercial invoice for international shipping should always include:
- Full name, address and contact details of the sender (exporter)
- Full name, address and contact details of the receiver (importer)
- Invoice date and a unique invoice number
- A clear description of each item, avoiding vague terms like "gift" or "sample"
- Quantity, unit value and total value of each item, plus the currency used
- Country of origin for the goods
- HS code for each product, where required — see our HS code guide for how to find the right code
- Total shipment weight and number of packages
- Reason for export, such as "sale of goods"
- Incoterm agreed with the buyer, for example DAP or DDP
- Signature of the sender, if the carrier requires it
A vague description such as "clothes" or "electronics parts" is one of the most frequent causes of delay. Instead, write something specific, like "men's cotton t-shirt, size M" or "USB-C charging cable, 1 meter." The more precise the description, the faster the item can be classified at customs.
Step-by-Step: Creating a Commercial Invoice
- List every item in the shipment separately, even if they belong to the same order.
- Write the real, declared value of each item — never leave it blank or write zero, even for returns or samples.
- Match the description and value to what is actually inside the box; customs can open parcels to verify.
- Add the correct HS code for each product category.
- Double-check the receiver's address and phone number, since mismatches can cause the invoice to be rejected.
- Keep a copy for your own records in case the buyer or customs authority asks questions later.
Common Mistakes Sellers Make
Many first-time exporters underestimate how strict customs can be about small details. Some frequent errors include:
- Declaring a lower value than the actual sale price to reduce duties — this is considered customs fraud and can lead to fines or seized goods
- Writing generic descriptions instead of specific product names
- Forgetting to include the HS code, which can trigger manual review
- Leaving out the Incoterm, which creates confusion about who pays duties
- Not matching the invoice total to the actual payment received from the buyer
Each destination country has its own thresholds and documentation habits, so always check the latest requirements with the carrier or the customs authority before shipping. Our country guides, such as the shipping to the USA guide and the shipping to Germany guide, cover general expectations for some of the most common destinations.
Creating Commercial Invoices the Easy Way
Manually filling out a commercial invoice for every order becomes time-consuming once your store grows. On Kargobaz, shipping labels and the required customs documents, including the commercial invoice, can be created online in minutes once you enter your order details. You can compare rates from carriers such as FedEx, UPS, Aramex, PTT, Widect and SMSA side by side before choosing how to ship, and check expected costs in advance with the international shipping cost calculator.
If you sell through a platform like Shopify, WooCommerce or eBay, connecting your store lets order details flow in automatically, which reduces the risk of typos on the invoice. Learn more about available store integrations. Creating an account is free and there are no contracts or minimum volume requirements, so it is worth setting up before your next shipment.
Final Checklist Before You Ship
Before handing over any international parcel, run through this short checklist: does the invoice match what's inside the box, is every value realistic, is the HS code present, and does the receiver's information match the shipping label exactly? A few extra minutes spent reviewing the document can save days of delay at customs.
