Overview

Commercial Invoice (CI) serves as written proof of the transaction between the buyer and the seller, recording detailed information about the goods, the transaction amount, and other necessary details. It not only plays a crucial role in goods settlement but also in customs clearance, foreign exchange settlement, tax refund, and other processes. This guide provides a detailed introduction to the definition, main functions, content requirements, types, and practical applications of Commercial Invoice in actual business.

It typically includes a description of the goods, quantity, unit price, total price, terms of the transaction, payment method, and other relevant information.

Application in Actual Business

Settlement and Payment

The buyer makes payment based on the commercial invoice, and the bank handles settlement procedures accordingly. For example, a US company purchases electronic products from a Chinese supplier; the supplier issues a CI per contract, the US company pays based on it, and the bank processes settlement.

Customs Declaration and Clearance

Customs authorities determine declared value and tariff rates based on invoice content. For example, when a German company exports auto parts to the US, it must provide a CI during export declaration for tariff determination.

Tax Refund Application

Export enterprises submit commercial invoices to tax authorities as refund basis. For example, a Chinese enterprise exporting clothing to Europe submits CI documentation to apply for export tax refunds.

Accounting

Commercial invoices serve as original vouchers for bookkeeping and auditing. For example, a Japanese company receiving overseas payment performs accounting treatment based on the CI to recognize revenue.
