One Contract Is Never One Contract: Risk Control Across a 26,500-Tonne Import Chain

The deal

A Chinese state-owned investment group decided to enter bulk-commodity importing. The commodity: heavy mineral concentrate — the raw material for zircon and titanium products — bought from an overseas mining supplier and resold to domestic processors. Two consignments were planned: a first of about 8,500 tonnes, and a second of about 18,000 tonnes.

The chain had more links than most buyers realize:

1. The international sale contract with the overseas miner (spot sale, letter-of-credit payment)
2. Third-party inspection of weight, moisture, and mineral content
3. Ocean freight — with laytime and demurrage exposure
4. Port custody — the cargo stored under a state inspection-and-certification group's supervision at two Chinese port locations
5. Freight forwarding at the port
6. Domestic resale to a downstream buyer

Every link had its own contract — and every contract could leak money. Our job was to make sure none of them did.

Step one: vet the supplier before the contract

Before any redline, we ran a background check on the overseas mining company. What the records showed was instructive: the supplier's visible export history was thin, and the trade data we could find showed shipments of a different commodity category than mineral sands — a signal worth flagging to the client before it committed to an LC.

This is the part of cross-border buying that feels optional until it isn't: the supplier on the other side of your contract is the party you'll be chasing if things go wrong. Know who they are before the money moves. (This is exactly what our verification service does.)

Step two: 55 redlines on the sale contract

The supplier's draft went through multiple rounds. Our final annotated version carried 55 comments — the kind of detail that decides whether an import deal is safe or speculative. A sample:

• Inspection appointment rights. If the seller appoints and pays the third-party inspector, the report may describe cargo that isn't what ships. We pressed for buyer involvement in selecting and paying the inspector — loyalty follows the fee.
• Quantity tolerance. A ±10% tolerance is on the high side for international trade; on a multi-thousand-tonne shipment, that's hundreds of tonnes of price exposure either way. Flagged and narrowed.
• Letter-of-credit documentation. An LC is only as safe as its documents clause. We required that the negotiating documents must include third-party certificates of weight, moisture content, and mineral content — so payment can only be triggered against verified cargo, not paperwork.
• "Tier 1 bank" is not a definition. The draft required the LC from a "Tier 1 bank" — a term with no accepted meaning. We pressed to name the issuing bank precisely.
• The demurrage trap. The draft let the vessel tender its Notice of Readiness "whether in port or not" (WIPON/WIBON), starting laytime — and demurrage charges — before the ship could even berth. We struck it and tied NOR validity to the vessel actually being in berth and ready. This single clause is worth real money on bulk cargo.
• Loading supervision. Even with a weight certificate, weighed cargo isn't necessarily shipped cargo. We advised the client to control the loading-supervision step, not just the paperwork.

None of these are exotic. All of them are the difference between a contract that protects the buyer and one that merely records the purchase.

Step three: every contract in the chain, each with a formal legal opinion

The sale contract was only the beginning. Over the following weeks we reviewed and annotated every agreement the cargo would touch, and issued a formal legal opinion for each:

The resale contract alone went through eight annotated versions. That's not pedantry — on a chain deal, your downstream contract must mirror your upstream one, or you end up owning the gap between them: quality you accepted from the seller but can't pass to your buyer, weight tolerances that don't match, payment terms that leave you financing the gap.

Step four: an orderly end

When the project later wound down, we drafted the termination agreement for the port custody arrangement — closing out the storage relationship cleanly, with the cargo accounted for and liabilities allocated. Projects don't just need good beginnings; they need controlled endings.

Why this matters to a foreign buyer

This matter sits on the opposite side of the table from our excavator case: there, we armed a foreign buyer against a Chinese supplier; here, we protected a Chinese buyer purchasing from overseas. Between the two sits the whole of cross-border trade:

• The supplier-vetting instinct is the same everywhere — know who you're contracting with before money moves.
• The dangerous clauses are the same everywhere — inspection rights, tolerances, payment triggers, demurrage, document control.
• A chain is only as strong as its weakest contract — and the weakest contract is usually the one nobody read closely: the custody agreement, the forwarding terms, the "standard" resale draft.

If you're buying from China, we've sat where your supplier's lawyers sit. We know what a well-drafted Chinese-side contract protects — and what it quietly leaves open.
