How to Read a Chinese Truck Supplier Proforma Invoice: A Line-by-Line Guide

A proforma invoice, often shortened to PI, is the quote turned into a document you can act on. It is not a receipt and not a final commercial invoice. It is the supplier's formal offer: this truck, at this price, on these terms, valid until this date. When you sign it and pay the deposit, the PI becomes the working contract for your order.

Because you pay against it, the PI deserves careful reading. Most disputes between buyers and Chinese truck suppliers trace back to something that was unclear, or simply missing, on this one page.

The Header: Who You Are Really Dealing With

Start at the top. Confirm the seller's full registered company name, not just a brand or a salesperson's name. This registered name should match the bank account you will pay later. A mismatch between the company on the PI and the name on the bank details is the single biggest red flag in China trade, so check it first.

Also confirm your own company details are correct, since these flow onto the bill of lading and the customs paperwork.

Vehicle Description and Specifications

Each line item should describe the truck clearly: chassis model, engine model and horsepower, drive configuration, gearbox, cab type, and body type if applicable. For trucks, vague descriptions cause real problems. "HOWO tractor" is not enough. You want the exact model, for example ZZ4257S3241W with a WD615.69C 371 hp engine and HW76 sleeper cab, or the SHACMAN H3000 with the specific engine and gearbox agreed.

If you discussed a specific configuration, such as tank capacity on a tanker or drum volume on a mixer, make sure it appears here. What is written on the PI is what the factory builds.

Price, Currency, and Incoterms

Look at three things together:

• The unit price and the total for the quantity ordered.
• The currency, almost always USD.
• The Incoterm, such as FOB Qingdao, CIF, or EXW.

The Incoterm decides where the supplier's responsibility ends and yours begins. FOB Qingdao means the price covers getting the truck to the port and loaded for RoRo or into a container, and you arrange freight and insurance from there. CIF means freight and insurance to your port are included. Never compare two quotes until you know which Incoterm each one uses, because they are not the same number.

Payment Terms and the Deposit

This section tells you how and when money moves. A common structure for trucks is 30 percent deposit by T/T with the balance due before shipment or against a copy of the bill of lading. Read it closely and confirm:

• The deposit percentage and the trigger for the balance.
• Whether the balance is due before or after shipment is confirmed.
• The bank details, including the account name, which must match the seller's registered name.

If anything about the banking looks off, or the details change at the last minute, stop and confirm by phone with your known contact before paying.

Lead Time, Shipment, and Validity

A serious PI states an estimated delivery lead time, often around 30 days from payment for new trucks already in stock or in production, plus a port of loading and a rough shipment window. It should also carry a validity date, because steel and component prices move. A quote from two months ago may no longer hold.

What Is Often Missing, and Worth Adding

Many proforma invoices leave out details that protect you. Before you pay, ask the supplier to add:

• Warranty terms and what they cover.
• Spare parts or tool kits included with the truck.
• Which documents they will provide: commercial invoice, packing list, bill of lading, and certificate of origin.
• Any inspection you have agreed to, such as a pre-shipment check with a photo and video report.

Getting these onto the document costs nothing and prevents most arguments later.

A Quick Pre-Payment Checklist

Before you send a deposit, confirm the six basics: the company name matches the bank account, the chassis and engine spec are exact, the Incoterm and currency are clear, the payment triggers make sense, the lead time and validity are stated, and the documents you need for customs are listed. If all six hold up, you are paying against a solid PI rather than a hopeful email.
