How to Read a Quantity Clause

The price clause tells you the money per unit. The quantity clause tells you how many units, how far that number may flex, and whose weight counts. People negotiate the price for an hour and initial the quantity because it looked like a round number. The flex around that number is where cargoes get bigger than the grain you have, or smaller than the ship you booked. Weight certificates are how the number is later proved, as described at https://goodsandgrain.trade/grain-weight-certificates.

The base amount and the unit

Read the figure and the unit in the same breath. Metric tons, short tons, and bushels do not survive a casual conversion. If the price is per bushel and the quantity is in tons, the contract should show how the conversion is done. A silent conversion is a second negotiation after loading.

Also read whether the amount is a minimum, a maximum, or a target. Those words are the difference between a promise and a ceiling.

More or less, and who chooses

Bulk contracts often allow a percentage more or less than the named quantity. The important half of that sentence is who chooses the final figure. Seller's option means the party loading can deliver anywhere in the band. Buyer's option means the party taking the grain can call the size. Operational convenience and commercial advantage both hide in that choice. A seller who planned the low end and meets a buyer who calls the high end has a sourcing problem.

Ask what notice is required before the choice is made, and whether the choice can be changed after a vessel is nominated. A tolerance that can be sprung at the berth is not the same tool as a tolerance declared at nomination.

Which scale closes the number

The clause should point at loaded weight, outturn weight, or a rule for splitting the difference. Shortage fights start when this sentence is missing. That pattern is described at https://goodsandgrain.trade/grain-shortage-claims-overview. If drafts and shore scales can both exist, say which one invoices. Tolerances and governing weight work together. A two percent tolerance does you little good if a different, harsher custom is what the other side thinks governs.

Moisture adjustments belong nearby. A quantity that shrinks because water was removed should not be described as a mysterious loss. Say whether dry weight or as-is weight is the traded quantity.

Fit the clause to the grain and the ship

A tolerance wider than the grain you can assemble invites a default. A tolerance narrower than the way a bulk vessel actually loads invites a technical breach on a normal operation. Talk to the person who will nominate the ship before you agree the band. Letters of credit add another constraint: a credit with no tolerance can turn an allowed contractual variance into a documentary discrepancy. Credits are explained at https://goodsandgrain.trade/letter-of-credit-grain-sale.

If you priced a futures hedge to the base quantity, know what happens to the hedge when the final figure lands at the edge of the band. The leftovers are a position.

Read it once aloud

Say: we will deliver this many units, plus or minus this percent, at this party's option, invoiced on this weight. If you stumble, the clause is not ready. Fix it while both sides still want the sale. Quantity disputes after a ship has sailed are a worse classroom.

This is a reading guide, not a substitute for the contract form you were offered. If the amount is large, have someone who ships bulk grain read the clause with you.

Frequently asked questions

Is a five percent tolerance always the custom?

Do not assume a percentage. Read the one in your contract and who is allowed to use it.

Does the tolerance apply to quality as well as weight?

Not by itself. Quality discounts and quantity tolerance are different clauses. Check both.

What if the credit and the contract disagree on tolerance?

Fix the credit or the contract before loading. The bank will follow the credit. The buyer may follow the contract. You do not want both.
