Rejecting a shipment feels decisive.

It can also be the moment a manageable technical problem becomes a legal, supply-chain and evidence problem at the same time.

Before sending “We reject the goods,” a buyer should know exactly what is wrong, which goods are affected, what the contract requires, what evidence has been preserved, and what rejection would trigger next.

The checklist below is designed as an operational sequence. It does not assume a universal right to reject. Contract and applicable law control.

Five questions to answer before touching the goods

1. What exactly is the alleged nonconformity?

Write it as a measurable difference.

Bad:

“Quality unacceptable.”

Better:

“Specification Rev D requires 3.00 ± 0.10 mm coating thickness; 18 of 60 sampled parts measured 2.62–2.78 mm using Method X.”

If you cannot state the problem precisely, do not start with a legal conclusion.

2. Which goods are actually implicated?

Identify:

  • SKU;
  • batch/lot;
  • serial number;
  • carton/pallet;
  • quantity;
  • production date;
  • delivery date.

Do not turn one bad sample into an unsupported statement about the whole shipment.

3. Which document created the requirement?

The source may be:

  • contract;
  • PO;
  • drawing;
  • approved sample;
  • technical standard;
  • packaging appendix;
  • regulatory clause;
  • later change order.

A quality file without a controlled specification version is vulnerable.

4. What test produced the result?

Record method, equipment, calibration, sample size, conditions and operator.

A buyer’s internal test may be useful, but if it differs from the agreed method, the parties may be arguing about methodology rather than product.

5. Can the current condition still be preserved?

Before sorting, reworking, scrapping or returning goods, ask whether those actions will destroy evidence.

Photograph in context. Quarantine representative units. Preserve packaging. Track sample custody.

Only after those five questions are answered should the buyer move into decision mode.

Decision 1: quarantine or continue using?

If continued use could contaminate evidence, damage downstream product or create safety/regulatory risk, quarantine may be appropriate.

But quarantine scope should be proportionate to the known facts.

Label:

  • HOLD;
  • lot;
  • date;
  • reason;
  • owner;
  • release authority.

Avoid mixing disputed and undisputed units.

Decision 2: inspect the whole shipment or sample?

The choice depends on:

  • lot size;
  • defect type;
  • agreed sampling plan;
  • severity;
  • destructiveness of testing;
  • cost;
  • downstream risk.

A 100% sort can create strong data but may be expensive and may alter packaging or chain of custody.

A sample can be efficient but must be defensible.

Use a technical expert where needed.

Decision 3: notify the seller now or wait for complete testing?

Waiting for perfect evidence can be risky if the contract or applicable law expects timely notice.

On the other hand, a premature accusation can overstate facts.

A practical notice can say:

  • issue discovered;
  • goods identified;
  • investigation continuing;
  • known measurements;
  • goods preserved;
  • seller invited to inspect;
  • rights reserved as appropriate.

If the CISG applies, examination and notice rules may matter, including Article 39’s treatment of notice of lack of conformity. Applicability and timing must be assessed for the actual transaction.

Decision 4: invite joint inspection?

For substantial disputes, joint inspection can reduce later arguments about:

  • sample selection;
  • condition;
  • test method;
  • quantity;
  • chain of custody.

It is not always required, but refusing reasonable access without a good reason can make factual resolution harder.

Decision 5: separate transit damage from production nonconformity?

Inspect:

  • container;
  • pallet;
  • outer carton;
  • internal packaging;
  • moisture;
  • impact;
  • seal;
  • loading/unloading photos.

Incoterms® 2020 can allocate certain delivery, cost and risk responsibilities if incorporated, but they do not decide the entire quality claim.

Do not ask “Who bears risk?” before identifying what happened and when.

Decision 6: identify the contractual specification hierarchy

Documents can conflict.

For example:

  • master agreement says Specification A;
  • PO attaches Specification B;
  • later email approves deviation C;
  • supplier drawing still shows A.

Find any precedence clause.

If none exists, counsel may need to interpret incorporation, amendment and course of dealing.

Decision 7: determine whether a regulatory requirement is involved

A product can meet private specifications and still fail a mandatory legal requirement.

Or the buyer may mistakenly treat a voluntary standard as mandatory.

Record:

  • jurisdiction;
  • regulation/standard;
  • version;
  • effective date;
  • product scope;
  • responsible party under the contract;
  • certificate/test report.

WTO TBT materials are useful for understanding the international context of technical regulations and conformity assessment, but a private contract dispute still turns on applicable law and facts.

Decision 8: quantify operational impact

Do not stop at defect percentage.

Measure:

  • production line downtime;
  • customer returns;
  • rework hours;
  • sorting costs;
  • replacement lead time;
  • expedited freight;
  • disposal;
  • downstream claims.

Separate documented cost from forecasts.

A projected loss is not the same as an incurred loss.

Decision 9: check whether the alleged problem can be cured

Possible cure paths:

  • sorting;
  • rework;
  • local repair;
  • replacement component;
  • relabeling;
  • documentation correction;
  • replacement shipment.

Whether the seller has a legal right or obligation to cure depends on contract and applicable law.

The operational question is simply: Is cure physically and commercially possible?

Decision 10: decide what to do with undisputed goods

If only one lot is affected, rejecting every shipment can increase damages unnecessarily.

Ask whether compliant units can be:

  • segregated;
  • accepted;
  • paid;
  • used safely;
  • released.

Do not create a bigger dispute than the evidence supports.

Decision 11: review payment consequences before withholding money

Quality and payment are often linked, but not automatically in the way either side assumes.

Check:

  • set-off clauses;
  • retention rights;
  • invoice allocation;
  • amount genuinely disputed;
  • effect of partial payment;
  • credit notes;
  • tax/VAT documentation.

Do not simply stop all payments without understanding the contractual and local-law consequences.

Decision 12: calculate the remedy ladder

Rank possible outcomes from least disruptive to most:

  1. clarification;
  2. document correction;
  3. sorting;
  4. rework;
  5. partial credit;
  6. replacement;
  7. negotiated price adjustment;
  8. partial rejection;
  9. broader rejection/termination;
  10. formal claim.

The legal availability of each option differs. The list is a negotiation sequence, not a statement of entitlement.

Decision 13: preserve a control sample

Keep enough representative material to allow future testing.

Record:

  • sample ID;
  • lot;
  • condition;
  • packaging;
  • seal;
  • storage;
  • custodian.

If destructive testing is planned, retain duplicates where feasible.

Decision 14: select the laboratory and test protocol

Do not choose a lab only because it is “on our side.”

Define:

  • accreditation if relevant;
  • exact test;
  • standard/version;
  • sample preparation;
  • tolerance;
  • uncertainty;
  • pass/fail rule;
  • witness rights;
  • reporting format.

A report with a famous logo but unclear methodology can still be disputed.

Decision 15: decide whether the seller gets a cure opportunity

This is a legal and commercial question.

A buyer may want immediate rejection. A seller may propose fast rework.

Consider:

  • urgency;
  • safety;
  • production schedule;
  • repeated failure;
  • prior cure attempts;
  • contract rights;
  • cost.

Local counsel should confirm whether a cure opportunity is required, optional or strategically sensible.

Decision 16: draft the rejection or reservation notice carefully

A serious notice should identify facts, not adjectives.

Include as appropriate:

  • contract/PO;
  • goods;
  • quantity;
  • delivery;
  • specification;
  • known deviation;
  • evidence;
  • requested response;
  • preservation/inspection offer;
  • rights reservation;
  • deadline based on the actual contract/law.

Avoid statements you cannot prove, such as “fraud,” “deliberate substitution,” or “entire shipment unusable,” unless evidence supports them and counsel approves the wording.

Decision 17: map what happens if the seller disagrees

Before rejection, know the next fork:

  • negotiation;
  • expert determination;
  • mediation;
  • arbitration;
  • court;
  • insurance claim;
  • carrier claim;
  • regulatory report.

A rejection notice without a next-step map may simply start another email cycle.

Decision 18: authorize the irreversible action

Only now decide whether to:

  • return goods;
  • scrap;
  • rework;
  • replace;
  • suspend;
  • reject;
  • terminate;
  • commence a formal claim.

Assign one executive or designated decision-maker.

Record the evidence and legal advice supporting the decision.

Distinguish physical refusal from legal rejection

A warehouse may refuse to unload damaged cartons for operational reasons. A buyer may quarantine goods after receipt. A legal “rejection,” however, can carry a specific meaning and consequences under the governing contract and law.

Do not let warehouse language make the legal decision accidentally.

If operations writes “REJECTED” in a receiving system, counsel should know what that status means internally and whether an external notice is still required. Likewise, accepting goods into a quarantine area should not automatically be described as waiving quality objections.

Use precise labels until the legal position is confirmed.

Put ownership beside every decision

Quality disputes often stall because engineering assumes legal owns the next step, legal assumes procurement is waiting for the lab, and procurement assumes the supplier is arranging inspection.

Add one more column to the action log:

Decision Owner Due Evidence needed Status
quarantine scope quality lead today lot map open
joint inspection procurement tomorrow seller availability open
test protocol engineering 48h contract standard open
notice wording legal/commercial 48h facts + deadline open
shipment disposition executive owner after test options + advice pending

This turns the checklist into an operating system rather than a document that everyone reads and nobody owns.

Revisit the decision if the facts change

A rejection decision should not become sacred merely because it was made early.

New facts may show that:

  • only one lot is affected;
  • transport damage explains part of the condition;
  • the agreed test method produces a different result;
  • a quick cure is technically feasible;
  • a mandatory regulatory issue is broader than first thought.

Record the changed fact, who reviewed it and whether the prior decision still stands. Controlled revision is stronger than pretending the first theory was perfect.

A counterexample: why “obvious defect” still needs process

Imagine 200 chairs arrive with visibly cracked armrests.

It seems obvious: reject everything.

Then the records show:

  • only 30 chairs were opened;
  • cracks appear on 12;
  • all 12 came from one pallet;
  • forklift damage is visible on that pallet;
  • remaining pallets are intact;
  • the carrier signed a damage notation.

The issue may still be serious, but the first impression—“factory defect across all 200”—has changed.

A disciplined checklist does not weaken the buyer. It prevents the buyer from locking itself into the wrong factual theory.

A second counterexample: “passes the drawing” may still be insufficient

A supplier shows that dimensions match the drawing.

The buyer then produces a contract appendix requiring a specific flame-resistance test for the destination market.

Now dimensional conformity is not the only issue.

Again, the key is the complete requirement hierarchy.

Sources and jurisdiction boundaries

The CISG is relevant only if its scope and connecting conditions are satisfied. The UK Sale of Goods Act 1979 is a national-law example, not a worldwide rejection rule. Incoterms® 2020 may allocate defined delivery/risk/cost responsibilities when incorporated but do not replace product-quality terms. WTO TBT materials concern government technical measures; they do not decide the private remedy.

Bottom line

Rejecting goods should be the end of an investigation sequence, not the beginning.

The safest order is:

define → identify → preserve → notify → test → quantify → map remedies → confirm legal basis → act.

That approach does not make the buyer slow. It makes the eventual decision much harder to attack.

General educational information only, not legal advice or technical testing guidance. Inspection, notice, rejection, cure, payment withholding and remedies vary by contract, product and jurisdiction.
