PO means purchase order. In China sourcing, it is usually the buyer’s order document, recording the core terms of a specific transaction.

Many small orders move forward on the supplier’s pro forma invoice alone. That is convenient, but it also means the supplier largely controls what is written. When a dispute happens, buyers often discover that the specifications were vague, inspection was not agreed, delay had no consequence, and the payee was never checked.

The short definition

A purchase order is the buyer’s document confirming a purchase. It often includes the supplier, buyer, product, model, quantity, unit price, total price, packaging, delivery date, payment terms, shipping term, inspection requirement, and attachments.

A PO does not automatically equal a complete contract. Its legal effect depends on whether the supplier accepted it, signed or stamped it, performed according to it , and whether there are other contract documents.

Statute Civil Code Arts. 490–491 when a PO becomes a contract

Art. 490www.court.gov.cn中华人民共和国民法典 - 中华人民共和国最高人民法院最高人民法院政务网站,最高人民法院网，最高人民法院，最高人民法院网是人民群众了解和联系最高人民法院的重要窗口，承载着司法公开、法治宣传、服务群众、接受监督等重要使命。是最高人民法院的政务网站，是最高人民法院在互联网上唯一的正式身份。www.court.gov.cn: a written contract forms when both parties sign, seal, or fingerprint; performance plus acceptance before signing also forms it. Art. 491: a successful online order submission forms the contract unless agreed otherwise.

Even where there is a formal contract, a PO remains useful because each batch needs specific quantity, specification, timing, and payment details.

What a PO should include

First, identify the supplier correctly. Do not use only an English name. Add the registered Chinese name and Unified Social Credit Code where possible.

Term Unified Social Credit Code (USCC)

An 18-character code assigned to every registered Chinese entity, printed on its business license and searchable on the National Enterprise Credit Information Publicity System国家市场监督管理总局国家企业信用信息公示系统查询中国企业登记、行政处罚、经营异常等信用信息的官方系统。www.gsxt.gov.cn. It identifies the legal party for contracts and lawsuits.

Second, specify the product. Model, material, dimensions, color, packaging, certification, drawing version, and sample number should be clear.

Third, state quantity, price, and payment. This includes deposit, balance, payment conditions, and bank details.

Fourth, state delivery and shipping terms. FOB Shanghai, Incoterms 2020 is clearer than simply writing “FOB China.”

Naming the port, as in FOB Shanghai, fixes where costs and risk pass from seller to buyer.

Fifth, state inspection and acceptance standards. Without a standard, it is hard to prove what counts as nonconforming goods.

Statute Civil Code Arts. 510–511 default quality standards

Where quality terms are silent, Arts. 510–511www.court.gov.cn中华人民共和国民法典 - 中华人民共和国最高人民法院最高人民法院政务网站,最高人民法院网，最高人民法院，最高人民法院网是人民群众了解和联系最高人民法院的重要窗口，承载着司法公开、法治宣传、服务群众、接受监督等重要使命。是最高人民法院的政务网站，是最高人民法院在互联网上唯一的正式身份。www.court.gov.cn fill the gap: mandatory national standards first, then recommended national, then industry, then usual or purpose-fit standards.

Why a PI is not enough

A pro forma invoice is usually issued by the supplier. It is useful for price, payment, and shipment arrangements, but it may not contain the buyer’s risk-control terms.

For example, a PI may state product name and price but omit drawing version, defect standard, inspection rights, delay consequences, refund terms, and dispute resolution.

Common mistakes

Specifications are scattered across WhatsApp, WeChat, email, and photos with no single version.

The PO uses an English trade name instead of the Chinese legal entity.

The supplier’s PI conflicts with the buyer’s PO, and no one confirms which controls.

Inspection is not tied to the balance payment, so the buyer discovers defects after payment.
Statute Civil Code Arts. 620–621 inspection and notice deadlines

Art. 620 requires inspection within the agreed period, or promptly if none. Under Art. 621www.court.gov.cn中华人民共和国民法典 - 中华人民共和国最高人民法院最高人民法院政务网站,最高人民法院网，最高人民法院，最高人民法院网是人民群众了解和联系最高人民法院的重要窗口，承载着司法公开、法治宣传、服务群众、接受监督等重要使命。是最高人民法院的政务网站，是最高人民法院在互联网上唯一的正式身份。www.court.gov.cn, defects not reported within that period, or within two years of delivery, are deemed conforming unless a warranty period applies.

The PO fails to reference the contract, NNN agreement, quality agreement, or attachments.

The bottom line

A PO turns the buyer’s purchase requirements into an order record that can be checked, accepted, and preserved as evidence. It may not replace a contract, but it can be a central part of the contract structure.

If you are placing an order with a Chinese supplier and are unsure how the PO, PI, contract, and payment terms fit together, contact me.
