12 Pricing, Assay, and Settlement Tips to Avoid Disputes in Bullion Export Contracts

Pricing, assay, and settlement are the three fault lines where most bullion export contracts fail. Disputes rarely start because one party is dishonest. More often, they start because the contract leaves room for different interpretations of purity, weight basis, pricing time, payable metal, deductions, or when and how money will be released.

For exporters operating across Africa and supplying international buyers, clarity is not a formality. It is risk control. If you are exporting bullion gold or related precious metal products, your contract should read like a process manual, not a handshake translated into legal language.

This article provides 12 practical tips to help exporters, buyers, and intermediaries reduce pricing disagreements, assay challenges, and settlement delays. Each tip focuses on writing unambiguous clauses, aligning technical procedures, and matching commercial expectations with actual workflows across refineries, vaults, and logistics providers.

1) Define the trade unit, weight basis, and what “weight” actually means

A surprising number of disputes come from a single word, “weight”. In bullion export contracts, weight can refer to gross weight, net weight, fine weight, shipping weight, or received weight after re melt and retesting. Make the contract specify the exact unit and the controlling measurement.

• State the unit: kilograms, troy ounces, grams. If you use kilograms, clarify whether pricing is converted to troy ounces and which conversion factor applies.
• State the basis: gross weight (including impurities) versus fine weight (pure metal content). Most buyers pay on fine weight after assay, not on gross.
• Define “delivered weight”: weight at departure airport, weight at importer customs, weight on refinery scale, or weight at a named vault.
• Specify tolerances: acceptable variance due to scale calibration, moisture, packaging, and handling. Without tolerance, any small difference can become an accusation.
• Require calibrated scales: identify which party’s scale is controlling, require calibration certificates, and specify the calibration standard and frequency.

Practical clause idea: “Payable fine weight shall be determined from received net weight on refinery scale, multiplied by final assay. Refinery scale certificate shall be final, subject to the dispute assay procedure in Tip 6.”

2) Separate indicative pricing from final pricing, and define when price becomes fixed

Parties often discuss a price early, then assume it is final. In bullion exports, pricing normally depends on final assay and a market reference price at a specific time. A contract should make clear whether any quoted price is indicative only, and the exact moment when the final price is locked.

• Choose a pricing method: fixed price, market linked price, or hybrid.
• Define the price fixing point: contract date, shipment date, arrival date, refinery intake date, or the date of final assay confirmation.
• Specify time zone and time window: “London PM Fix”, “LBMA AM”, or a specific exchange reference at a specified time.
• Clarify who initiates the price fix: buyer, seller, or mutual. If mutual, define the communication method and deadline.
• Include what happens if fixing is missed: default fix date or fallback pricing formula.

When both parties know exactly when the price is fixed, they stop arguing about “the price we agreed” and focus on executing the agreed process.

3) Use a named reference price and a named FX reference, then document the conversion method

Market linked contracts must reference a trusted, verifiable benchmark. Ambiguity about the benchmark, or currency conversion, can create hidden losses and disputes.

• Reference price source: LBMA Gold Price, COMEX settlement, or another agreed benchmark. Write the exact name.
• Define the quote type: spot, fix, settlement, bid, ask, or mid. Do not assume “spot” means the same thing to both sides.
• Specify currency: USD is common. If settlement is in another currency, define the FX conversion clearly.
• FX source: bank telegraphic transfer rate, central bank reference, Reuters, Bloomberg, or a named bank rate at a defined time.
• Rounding rules: decimal places for ounces, kilograms, price, and FX rate. Small rounding differences can add up at large volumes.

Good practice is to keep pricing in USD based on an international benchmark, then separately define settlement currency and FX conversion if needed.

4) Define payable metal content, refining charges, and all deductions in a single schedule

Most pricing disputes are not about the headline benchmark price. They are about deductions, charges, and what is considered payable. If these are scattered across emails, they will be argued later.

• Payable percentage: for example, “99.5 percent payable on fine gold content” or another agreed payable percentage tied to assay.
• Minimum purity: minimum acceptable fineness at shipment, and what happens if it is below minimum.
• Treatment charges and refining charges: fixed per kilogram, per ounce, or percentage. State clearly which applies.
• Penalties: for excessive impurities, high silver content, base metals, or other out of spec elements. Define thresholds and penalty rates.
• Logistics and compliance costs: vault fees, refinery intake fees, assay fees, insurance, export permits, and who pays each one.

Put all deductions into a single pricing and deductions schedule as an appendix. If a deduction is not in the schedule, it should not be chargeable without written amendment.

5) Specify the assay method, laboratory standard, and sample handling chain of custody

Assay disputes often result from the difference between informal testing at origin and a refinery grade determination at destination. You reduce conflict by specifying the test method and handling process, not just “assay will be done.”

• Assay method: fire assay, ICP, XRF screening plus fire assay confirmation, or an agreed combination.
• Laboratory standard: ISO 17025 accredited laboratory, named refinery lab, or named independent lab.
• Sample preparation: how the bar is drilled, how many drillings, where on the bar, and how sample is homogenized.
• Sealing and labeling: tamper evident packaging, unique sample ID, date, and signatures by both parties or their agents.
• Chain of custody: define who holds the sample at each stage, and how custody changes are documented.

Even when the buyer uses a refinery, the seller should insist on documented sampling and chain of custody. This is not mistrust. It is quality control and protects both sides if there is later disagreement.

6) Build a two stage dispute assay procedure, including an independent umpire lab

No assay process is perfect. A strong contract anticipates disagreement and provides a fair method to resolve it quickly, without stopping payment indefinitely.

• Primary assay: define the primary lab or refinery assay that triggers provisional settlement.
• Dispute trigger: define the variance threshold, for example if the seller and buyer results differ by more than a stated fineness or percentage.
• Umpire lab: name an independent accredited lab, or define a method for selecting one from an agreed list.
• Sample selection: define which sealed retained sample goes to the umpire lab, and who ships it.
• Cost allocation: loser pays, split, or based on variance. Make it explicit.

Include a timeline. For example, umpire assay must be completed within a stated number of business days once the dispute is declared. Without deadlines, disputes can be used as a delay tactic.

7) Clarify provisional settlement versus final settlement, and link each to a document set

Cash flow is critical for exporters. Buyers often insist on final settlement after refinery assay. Exporters often need an earlier payment event. The solution is to define provisional settlement and final settlement with clear documents that trigger each stage.

• Provisional settlement: percentage of estimated value payable upon arrival, vault intake, or preliminary assay.
• Final settlement: balance payable after final assay and final pricing fix.
• Documents for provisional payment: airway bill, packing list, export permit, certificate of origin when applicable, vault receipt, insurance certificate.
• Documents for final payment: final assay certificate, final weight certificate, final invoice, and the pricing confirmation statement.
• Credit notes and debits: define how adjustments are issued and within what time frame.

This structure decreases disputes because each payment stage has objective triggers and does not rely on “trust me, it is being processed.”

8) Define settlement timelines, banking rails, and what counts as “payment made”

Settlement disputes often come from timing and banking details. One party considers payment “made” when they send the transfer instruction. The other considers it “made” only when funds are credited.

• Timeline: specify business days from a defined trigger, such as receipt of complete documents, or confirmation of assay.
• Payment method: SWIFT transfer, bank to bank transfer, or another agreed method.
• Payment confirmation: SWIFT MT103 copy plus bank value date. Define what evidence is required.
• Beneficiary details: beneficiary name must match contract party, account currency, intermediary bank if needed.
• Bank charges: OUR, SHA, or BEN. If not specified, parties will argue about short payments.

Also include a clause for what happens if compliance checks delay the transfer, and which party bears the risk of additional banking compliance requests.

9) Agree on Incoterms style delivery point and the risk transfer moment, then align it with assay and title

Disputes happen when risk, title, and assay responsibility are not aligned. If the contract says the buyer owns the metal at departure, but assay and settlement happen at destination, both sides can claim the other bears loss risk.

• Delivery point: identify whether delivery is at origin, airport, named vault, or refinery intake.
• Risk transfer: define the exact moment risk passes, such as “upon acceptance at named vault” or “upon handover to carrier.”
• Title transfer: specify when ownership transfers, and whether it is conditional on payment.
• Insurance: who insures, for what value, and up to what point. Ensure insured value matches pricing logic.
• Assay and loss events: clarify what happens if there is damage, partial loss, or tamper evidence during transit.

Alignment matters. If seller retains title until full payment, the contract should still specify who bears transit risk and who controls the claim process.

10) Treat packaging, sealing, and bar identification as pricing protection, not logistics details

Packaging errors can become assay disputes. If bars are not uniquely identified and sealed, any purity disagreement becomes almost impossible to resolve because the parties cannot prove which sample came from which bar.

• Unique IDs: bar number, batch number, or consignment number, recorded in the packing list.
• Seals: tamper evident seals with recorded seal numbers and photos at packing.
• Photographic record: bar photos showing markings and packaging, plus weight scale photos if feasible.
• Packaging spec: materials, moisture control, and protection against contamination.
• Witnessing: allow buyer representative, independent inspector, or a third party logistics provider to witness sealing.

This does not slow trade if standardized. It speeds settlement because fewer questions are raised during intake at the vault or refinery.

11) Control “out of specification” outcomes with pre agreed remedies

When metal does not meet minimum purity or contains unexpected elements, disputes escalate quickly. Prevent escalation by defining what “out of specification” means and how the parties will respond.

• Specification table: define expected fineness range and maximum impurity levels, if relevant.
• Right to reject: define whether the buyer may reject, return, or require refining with additional charges.
• Price adjustment: specify penalty pricing, additional refining charges, or payable reduction formula.
• Segregation: require the consignment to be segregated during dispute, with documented storage and custody.
• Fraud indicators: define steps if tampering, fake bars, or adulteration is suspected, including involvement of authorities and suspension of further shipments.

Clear remedies protect legitimate exporters. If quality is genuine but variable, the contract provides a predictable commercial outcome instead of a relationship crisis.

12) Reconcile settlement with a final statement, then close the trade with a dispute window and audit rights

Even after payment, issues can arise from misapplied deductions, wrong FX rates, or missing documents. The solution is to formalize the closeout process like a mini audit.

• Final settlement statement: a single document showing gross weight, net weight, final assay, fine weight, benchmark price, FX rate if any, all deductions, and the resulting net payable.
• Signed acceptance: require both parties to sign or confirm by email within a defined period.
• Dispute window: limit the time to raise pricing or settlement disputes, for example 10 to 30 business days after final statement.
• Record retention: define how long each party must retain assay records, certificates, photos, and bank confirmations.
• Audit rights: limited audit of relevant records, such as scale certificates and assay logs, subject to confidentiality.

Closing a trade properly reduces repeat disputes across multiple shipments. It also builds a reliable performance record that helps exporters obtain better terms with buyers, refiners, and logistics partners.

Putting the 12 tips into a simple contract workflow

If you want to turn the tips into a practical operational flow, structure the contract around these stages:

• Pre shipment: agree specifications, packaging, sampling plan, indicative pricing terms, and documentation list.
• Shipment and intake: define delivery point, risk transfer, inspection, weighing, and provisional settlement triggers.
• Assay and price fix: define assay method, dispute assay, price benchmark, fixing time, and conversion rules.
• Settlement: define provisional and final settlement amounts, payment rails, timelines, bank charges, and compliance delays.
• Closeout: final statement, dispute window, record retention, and limited audit rights.

Common red flags that typically lead to disputes

When reviewing a bullion export contract, treat the following as red flags that should be corrected before shipping:

• Pricing clause says “spot” but does not name the benchmark or the fixing time.
• Contract says “assay as per refinery” with no method, no retained sample, and no dispute procedure.
• Deductions are described vaguely, for example “refining and other applicable charges.”
• Payment timeline is tied to “buyer confirmation” instead of objective documents.
• Risk and title are unclear, or conflict with the delivery point and insurance clause.
• No definition of what happens if the consignment is out of specification.

Cleaning up these issues before execution is much cheaper than arguing after arrival when the metal is already under another party’s control.

Conclusion

Bullion export contracts work best when pricing, assay, and settlement are drafted as a complete system. The exporter needs predictable cash flow and fair verification. The buyer needs reliable quality and enforceable controls. The best contracts do not depend on goodwill. They convert goodwill into clear steps, clear documents, and clear timelines.

By applying these 12 pricing, assay, and settlement tips, exporters and international buyers can reduce misunderstandings, accelerate settlement, and protect long term trade relationships in the precious metals export market.
