Identify the implied obligation before reading the exclusion
Section 62 of the Sale of Goods Act, 1930 allows a right, duty or liability arising by implication of law under a sale contract to be negatived or varied by express agreement, the parties’ course of dealing or usage binding both parties. It is not a finding that every seller disclaimer is effective. First identify the actual implied term, the asserted variation and the evidence that makes that variation part of the relevant contract. This guide focuses on commercial goods-contract evidence, not consumer-law exclusions or a universal drafting formula.
Read the applicable text: Sale of Goods Act, 1930: sections 12–16, 59 and 62.
Separate three routes of variation
For an express agreement, establish incorporation, the accepted version and the obligation actually addressed. For a course of dealing, preserve the relevant prior transactions rather than pointing to one untested historic invoice. For usage, establish both the content of the asserted usage and why it binds both parties. Section 62 does not prescribe a minimum number of past orders or a universal percentage tolerance. Evidence of repeated performance can matter, but a count of transactions alone does not settle the legal conclusion.
Read exclusions narrowly enough to identify their target
A term addressing delivery tolerance is not necessarily an exclusion of title, grade, quality, fitness or remedies. Section 12 distinguishes conditions and warranties by construction of the contract. Section 16(4) says an express warranty or condition does not negative one implied by the Act unless inconsistent with it. Therefore compare the provisions actually claimed to conflict; do not infer that an express warranty document automatically removes every implied protection. Resolve conflicting document priority and competing purchase/sale terms before applying the financial model.
Review the transaction and remedy separately
Under section 13(2), acceptance of goods or part of them in a non-severable contract generally means a condition breach must be treated as a warranty breach, unless an express or implied term preserves rejection. Section 59 permits price diminution or extinction or damages for breach of warranty; further damage may be claimed without recovering the same loss twice. Even if a particular obligation remains applicable, acceptance, waiver, severability and the facts may affect rejection or monetary relief. Conversely, an agreed adjustment of one obligation need not eliminate all remedies for another breach. Record the nature of the claimed loss and any negotiated settlement without announcing that the full invoice value is automatically recoverable. This article gives no opinion that a particular disclaimer overrides mandatory law outside the Act.
Use calculations to expose scope differences
Quantify the result under the actual assumed clause, and show the amount affected by a different reading. A sensitivity calculation helps identify which contractual ambiguity matters; it does not let a party elect the most favourable legal interpretation. Preserve measurements, accepted versions, prior orders, communications and usage evidence. Before settling, document which variation is established, which obligations remain and what loss or price adjustment is supported. Keep internal commercial concessions separate from an assertion that the statute imposes the same concession on everyone.
Six worked illustrations
All facts and amounts are fictional. Calculations illustrate the stated assumptions, not a predetermined legal outcome.
Illustrative example 1: A quantity tolerance is an assumed contract term
An expressly agreed ±2% delivery tolerance on 10,000 units gives a range of 9,800–10,200 units. Delivery of 9,750 is 50 below the lower boundary. Section 62 does not itself supply 2%; the agreement and its legal effect must be established.
Illustrative example 2: A cap with a defined base
Assume a validly applicable negotiated adjustment cap equals 5% of the affected batch price of ₹8,00,000. The arithmetic cap is ₹40,000. Applying it to an unrelated ₹20,00,000 annual purchase total would give ₹1,00,000, a ₹60,000 difference. Whether the cap governs the actual liability needs separate legal analysis.
Illustrative example 3: A narrowed variation leaves other quantities untouched
A supported amendment changes one specification for 300 of 1,000 items at ₹250 each. Its specified population is ₹75,000 out of the ₹2,50,000 order value; 700 units and ₹1,75,000 remain outside that stated quantity scope. Do not assume a variation for 300 units changes the whole order.
Illustrative example 4: Prior-dealing coverage is an evidence measure
A reviewer identifies 12 earlier orders, but only 8 contain the same accepted term; 4 use another version. The claimed consistent-term population is 8/12, or 66.67% rounded to two decimals. That percentage exposes mixed evidence; it is not a statutory threshold proving a course of dealing.
Illustrative example 5: Usage must be proved before applying its number
A party asserts a binding trade usage allowing a 1% measurement variation on 5,000 kg. If legally established on those terms, the allowance is 50 kg. A 70 kg variance exceeds it by 20 kg. Merely knowing the calculation does not establish the usage or that it binds the other party.
Illustrative example 6: Settlement is not an automatic statutory discount
For 400 affected items the parties agree ₹15 per item in a documented settlement against ₹1,20,000 outstanding. The agreed adjustment is ₹6,000 and the residual ₹1,14,000. Preserve its scope and any reservation of other claims; section 62 does not independently prescribe ₹15 per item.

Sixteen practitioner FAQs
1. Does section 62 automatically validate a disclaimer?
No. Establish the source, incorporation, scope and applicable legal limits.
2. Which routes does the section recognise?
Express agreement, course of dealing and usage binding both parties.
3. Is one old invoice conclusive prior dealing?
Do not assume that. Review the actual transaction history and contrary evidence.
4. Is there a statutory minimum number of orders?
Section 62 does not state one.
5. Does a trade custom bind every buyer?
The section requires usage that binds both parties; evidence is necessary.
6. Does the Act prescribe a 2% tolerance?
No. The example tolerance is assumed contractual wording.
7. Can a quantity term exclude title obligations automatically?
Do not infer that. Identify the specific obligation and scope of the variation.
8. Does an express warranty remove every implied condition?
Section 16(4) requires attention to inconsistency rather than assuming total displacement.
9. What if buyer and seller documents conflict?
Resolve incorporation and priority before calculating the contractual outcome.
10. Can a variation apply only to part of an order?
Yes on its established terms; preserve the quantity scope.
11. Does proving a breach always permit rejection?
No. Examine the applicable remedy, acceptance and waiver rules.
12. Does invoice exposure equal damages?
No. Support actual loss and the relevant remedy separately.
13. Is a percentage sensitivity an election?
No. It illustrates consequences of different assumptions, not a choice of law.
14. Does this guide override consumer protections?
No. Other mandatory law requires its own analysis.
15. How should a concession be recorded?
As the actual agreed settlement with its defined scope, rather than a universal statutory discount.
16. What closes the review?
A supported conclusion on the variation, remaining obligations and the agreed or legally assessed remedy.
