Cable Supply Contract Clauses: Copper, Delivery & Liability
Most cable contract disputes aren't about the cable — they're about three clauses nobody read carefully: how the copper price moves, what "on time" means, and who eats the loss when something goes wrong. Here's what to negotiate in each one.
Supply Contracts · Copper · LiabilityHere's a pattern you'll recognise if you've been buying cable for a while: the contract that caused the dispute was never actually a bad contract — it was a good contract with three vague clauses. The copper adjustment said "per LME" but not which day. The delivery clause said "as scheduled" but not what happens when it slips. And the liability clause silently capped everything at the invoice value. When the deal went sideways, nobody could point to what they'd actually agreed.
This guide walks the three clauses that decide most cable-contract outcomes — copper pricing, delivery scheduling, and damages — with real examples of how suppliers draft them and what buyers should push back on.
1. The Copper Price Clause: Make the Mechanism Explicit
Copper dominates cable cost — so "the price" is really "the price of copper on a date we both agree."
Copper-price adjustment clauses are standard across the industry. The typical structure looks like the Essex Furukawa model: the buyer is charged on an LME Copper Cash Settlement basis, plus a cathode premium, plus procurement costs, plus processing costs — and if there isn't enough copper credit on the day of delivery, the missing quantity is charged at full-price conditions. Other suppliers simply state that offers are subject to adjustment for metals based on prices on the first available day after order receipt.
| Element of a copper clause | Why it matters | What to pin down |
|---|---|---|
| Reference benchmark | LME Copper Cash Settlement is the industry base | Explicitly named — "LME", not "market price" |
| Reference date | The single biggest litigation flashpoint | Order-receipt day? Delivery day? One month before delivery? |
| Premiums / surcharges | Cathode premium, procurement and processing adds up | Percentages stated in writing (e.g. 2% + 6.5% in one model) |
| Copper credit on delivery | If you under-bought copper credit, you pay full price on the shortfall | How the credit account is tracked and reconciled |
| Split when price falls | The clause cuts both ways | Buyer should benefit on the downside too, not only pay on the upside |
| Published commercial arbitration records frequently show disputes starting exactly here: the agreed formula uses an LME reference date, but the parties argue endlessly over the calculations, debit notes, and schedules. Clear drafting prevents this. | ||
Buyer's move: fix the reference date in one sentence and attach a worked example to the contract — "per LME Copper Cash Settlement on the order-receipt date, plus the agreed premium". A worked example costs five minutes now and saves a year of argument later.
2. Delivery Schedules: "Estimates" vs. "Essence"
Two contracts can both say "delivery in 8 weeks" and mean entirely different things.
Read a cable supplier's standard terms and you'll often find that quoted delivery times are "an estimate only" and that "time is not of the essence of the contract" — which, in plain terms, means a late delivery isn't a breach. Buyers' contracts push the opposite way: fixed dates, with consequences attached.
| Delivery issue | Supplier-standard stance | Buyer negotiation target |
|---|---|---|
| Are delivery dates binding? | "Estimate only, time not of the essence" | Binding schedule for your critical lines, or at least agreed milestones |
| Force majeure | Extends delivery period by the delay period | Narrow the trigger to genuinely unforeseeable events, with notice duty |
| Short delays | Compensation excluded below 2 months in some terms | A penalty that starts before 2 months for critical-path cable |
| Over/under length | ±10% on cut lengths with price adjustment | Confirm the tolerance fits your installation plan |
| Storage of goods | If dispatch is delayed by buyer, seller charges storage (≥1%/month in one model, max 10%) | Fix the storage rate before it's a surprise |
Read the practical trade: suppliers genuinely can't fully control delivery — copper availability, cable-length planning, and freight all move. The win isn't forcing an impossible guarantee; it's getting early-warning obligations, a defined penalty that bites on your critical path, and a written extension mechanism instead of silence.
3. Liquidated Damages: The Structure That Actually Bites
Delay compensation is only real if the percentage, the trigger, and the cap are all agreed in advance.
Buyer-side sample clauses in commercial contracts commonly use a weekly percentage with a cap. Three common shapes:
| Shape | Rate | Cap | Notes |
|---|---|---|---|
| Weekly rate A | 1% of net price per completed calendar week | 5% of net price of late goods | Supplier may prove lesser actual damage |
| Weekly rate B | 0.5% per full week of default | 5% of value of parts not delivered in time | Beyond cap only in specified cases |
| Daily rate | 0.05% of paid contract price per day | Amount of the guarantee deposit | Common where a deposit backs the order |
| Some clauses add a grace period before penalties accrue, and allow penalty payments to be credited against the next order — worth asking for if your relationship is long-term. Whether such figures are enforceable as liquidated damages rather than an unenforceable penalty depends on the governing law. | |||
Repeat defaults usually entitle the buyer to cancel outstanding orders after a warning. And on the other side of the table, supplier terms often reserve big lump-sum claims if you refuse to accept goods — TKD Kabel, for example, claims 20% of net order value for standard goods and up to 100% for cable already cut to size. Buyer non-performance is as real a risk as supplier delay.
4. Liability and Consequential Damages: Know What You're Waiving
The most expensive sentence in a cable contract is usually the one that excludes "consequential damages".
Nearly every cable supplier's standard terms cap liability and carve out consequential loss. The AEI Cables model is representative: total liability limited to the contract price, with no liability for "pure economic loss, loss of profit, loss of business, depletion of goodwill... whether direct, indirect or consequential." German suppliers (TKD, Kenex) take the intent-and-gross-negligence route: unlimited liability only for intent and gross negligence, with ordinary negligence capped at foreseeable damage.
What this means for you: if a failed cable batch shuts down a production line for three weeks, a contract that limits liability to the cable's invoice value doesn't compensate the shutdown — it refunds the cable. That's a commercial decision, not a mistake. Make it deliberately: for safety-critical lines, a genuine consequential-damages position — or at least a higher cap — is worth negotiating, not assuming.
Force majeure clauses often interact here: one supplier's terms state that if force majeure makes performance impossible, the seller may reduce quantities, postpone dispatch, or cancel — "without the Buyer being entitled to any claims for damages or other compensation." Always check what your contract does on force majeure before it happens.
5. A Review Checklist for Your Next Cable Contract
- Copper: named benchmark, single reference date, stated premiums, downside sharing, a worked example attached.
- Delivery: is the date an estimate or binding? What happens on force majeure? Is there an early-warning duty? Is the ±length tolerance acceptable?
- Liquidated damages: examples in commercial supplier terms use a percentage per week (0.5–1%), a cap (typically 5%), grace period, credit against next order, and cancellation right on repeat default — check enforceability under the governing law.
- Liability: cap amount, what's excluded (consequential/loss of profit), and whether intent/gross negligence is carved out.
- Spec & conformity: the cable spec is incorporated by reference; test reports and certificates listed; inspection rights stated.
- Dispute resolution: governing law, arbitration seat, and the escalation path — agreed before the dispute, not during it.
6. What a Contract-Ready Supplier Looks Like
The best counterparty isn't the one with the most favorable paper — it's the one who drafts clearly and answers the hard questions.
| Clause area | Vague supplier | Clear supplier / SORIVO |
|---|---|---|
| Copper mechanism | "Subject to metal prices" — undefined | Explicit LME reference date and premium, worked example provided |
| Delivery | "As soon as possible" | Real lead times, defined milestones, honest early warning |
| Liability | Standard-form exclusions buried in fine print | Plain-language cap and exclusions discussed before signing |
| Spec conformity | Datasheet "for reference" | Spec incorporated by reference with test reports and certificates |
| Disputes | Silent, discovered when it's too late | Governing law and escalation path agreed up front |
| A supplier who explains their contract clearly on day one is signalling how they'll handle a problem in year three. | ||
Cable Contract FAQ
How do copper price adjustment clauses work?
The cable price is tied to an LME copper benchmark on a defined date, plus a cathode premium and procurement/processing costs. The buyer effectively pays for the copper content at the agreed reference date, and adjustments flow both ways. The exact reference date and formula are the most common source of disputes.
What is a typical liquidated damages clause for late delivery?
Examples found in commercial supplier terms include 0.5–1% of the net price per week of delay, capped at 5% of the late goods' value, or a daily penalty (e.g. 0.05%) capped at the guarantee deposit. Enforceability depends on the governing law and whether the agreed amount is legally treated as liquidated damages or an unenforceable penalty.
Why do cable suppliers exclude consequential damages?
Cable is a low-margin, high-volume product, and its failure can cause losses (production shutdown, lost profit) far exceeding the cable's value. Suppliers cap liability to the contract price and exclude consequential loss because otherwise one bad batch could bankrupt them. Buyers should negotiate a higher cap or carve-outs for safety-critical lines.
What does "time is not of the essence" mean in a cable contract?
It means late delivery isn't treated as a breach of a fundamental term — the buyer can claim the agreed liquidated damages (if any) but generally can't treat the contract as ended. Buyers should push for at least binding milestones on critical-path deliveries.
Does SORIVO negotiate these contract clauses?
