The bill of lading and invoice you see may be completely different from the stubs stored in the freight forwarder system. This is the most easily bypassed risk point in trade financing.

Verifying the authenticity of bills of lading and invoices cannot stop at "the document looks real". High-quality counterfeit invoices can pass ordinary website checks because their serial numbers are real, but the product name, amount and consignee are all altered. Pre-delivery trade financing essentially uses "future cargo rights" to exchange for funds, and the core of authenticity verification is to connect off-chain facts (where the goods are, who is the carrier, customs declaration status) with on-chain documents.
Different Verification Logic for Bills of Lading and Invoices
The Bill of Lading (B/L) is essentially a document of title to the goods, and forging a B/L equals forging ownership. The core of B/L verification is not checking its appearance, but confirming the carrier recognizes this B/L as valid.
Formal electronic B/L platforms (such as TradeGo, "Silk Road Cloud Chain" BRITC) issue and circulate B/Ls on the blockchain, and are certified by the IG P&I Club (International Group of P&I Clubs). Only 13 electronic B/L platforms worldwide have obtained this certification, and the electronic B/Ls they issue are covered by insurance the same as traditional paper B/Ls. If the B/L provided by the financing party is not retrievable on these platforms, you need to stay alert.
For paper B/Ls, the verification path is to contact the shipping company or freight forwarder that issued the B/L, and check whether the B/L number, vessel name and voyage, product name, and consignee are consistent with the stubs. Tax inspection cases show that some people found that the information on 15 freight invoices was completely inconsistent with the stubs after on-site verification with the invoicing party: the invoice itself was real, but the underlying transaction was fake.
Invoice verification is relatively mature, but "real invoice" does not equal "real transaction"
There are three official channels for invoice authenticity verification:
National VAT Invoice Verification Platform (https://inv-veri.chinatax.gov.cn): Enter the invoice code, number, invoicing date and check code, and the system will return the verification details. You need to install a root certificate for first-time use.
Electronic Tax Bureau: After logging in, conduct single or batch verification through "Digital Tax Account" → "Invoice Verification".
Electronic Tax Bureau App: Scan the invoice QR code to complete verification.
But a real invoice does not mean the corresponding trade actually happened. A Dalian-based international trading company got real invoices (with real serial numbers that can be checked on the official system), but the corresponding transportation service did not exist at all: the invoices were illegally issued by a freight forwarder staff, a "real invoice for fake transaction" situation. So invoice verification must be paired with cross-validation: check whether the product name, quantity, amount, buyer and seller on the invoice are consistent with the bill of lading, customs declaration form and contract.
One-Stop Verification Idea: Cross-Validate Three Types of Documents
The Suifenhe Free Trade Zone has launched a "customs declaration + waybill + insurance policy" three-document financing model, which realizes electronic issuance, circulation, storage and traceability on the blockchain platform. All documents are cross-verified on the chain in real time, and the verification process only takes seconds. A similar service is launched by Shenzhen's "Credible Data Verification Service Platform for Import Trade in Foreign Trade Supply Chain": it integrates data including customs declarations, tax receipts, bills of lading and logistics updates from the international trade "single window", and financial institutions use these data to cross-verify with the order information provided by core enterprises.
As an investor, you may not have access to these professional platforms, but you can require the financing party to show you the following cross-validation results:
Whether the consignor, consignee, goods description and quantity on the invoice and bill of lading are consistent
Whether the declared value on the customs declaration form matches the invoice amount
Whether the logistics tracking information (vessel name and voyage, container number, ETA) is consistent with the bill of lading
The "CA Seal for Document Exchange" service launched at Ningbo Port uses encrypted electronic signatures to technically eliminate the risk of B/L misappropriation and forgery, and the entire signature process is traceable and verifiable. The popularization of such infrastructure is making document forgery increasingly costly.
Extra Risks for Pre-Delivery Financing
Financing before goods are delivered means the B/L you get may be a "advanced B/L" (issued before the goods are loaded on the vessel) or "anti-dated B/L" (with the loading date backdated). Both situations are serious discrepancies in letter of credit settlement, but are hard to identify automatically in on-chain financing.
The verification method is: Check the real-time position and port call records of the vessel through the shipping company's official website or third-party logistics tracking platforms (such as MarineTraffic), to confirm whether the goods have actually been loaded and departed. If the B/L provided by the financing party shows the goods are already shipped, but the vessel position and track do not match, it is a dangerous red flag.

Final Verification Checklist
The ultimate standard for document authenticity verification is cross-validation. After completing all the steps above, you should confirm all the following points:
The invoice passes the State Taxation Administration platform verification, and its status is "normal" (not voided, not red-lettered)
The bill of lading can be queried in the carrier's system or the IG-certified electronic B/L platforms (such as TradeGo, BRITC)
The key information of the invoice and bill of lading (consignor, consignee, product name, quantity) match each other
The loading date on the bill of lading is basically consistent with the actual port departure date of the vessel
If the financing party cannot provide independently verifiable B/L information, or the invoice passes verification but the B/L cannot be tracked, it means the document chain is broken: the underlying asset of this financing may not exist at all.
