One Delivery Date Is Not a Lead Time

A purchase order that says "delivery by 15 May" has told you when the goods are wanted. It has not told you when the tape must be woven, when the dye lot must be approved, when the sliders must clear inspection, or when the cartons must be booked. Those are the dates that actually determine whether the fifteenth is achievable, and none of them appear in a clause that names a single day.

Lead time in zipper supply is a chain of dependent steps, and the chain breaks at its slowest link. A contract that writes the chain down converts a vague promise into a schedule that can be monitored, and it gives both parties an early warning system rather than a post-mortem.

Break the Timeline Into Milestones

  1. Order confirmation. Seller confirms quantity, price, specification revision and ship date in writing within 3 working days. Silence is not confirmation.
  2. Material readiness. Tape yarn and sliders allocated; Seller notifies Buyer of any substitution within 5 working days of order.
  3. Lab dip or bulk approval. Buyer responds to a submitted shade within 3 working days; no response means the submitted shade is approved for that lot only.
  4. Production start. Seller notifies the actual start date, not the planned one, within 24 hours of the line running.
  5. Pre-shipment inspection. Completed at least 5 working days before the ship date, with the report issued the same day.
  6. Handover to carrier. Goods ready for collection on the confirmed date, with packing list and test reports attached.

Each milestone needs an owner and a consequence. A milestone that only exists to be reported is a status update, not a control.

Delay Liability Clause Block

CLAUSE 11 - DELIVERY AND DELAY
11.1 Ship date: as stated on the accepted order confirmation.
11.2 On-time means goods ready for collection at Seller's
     dock on the ship date, with documents complete.
11.3 Grace period: 3 calendar days, no liability.
11.4 Delay charge: 0.5% of the value of the delayed
     quantity per calendar day, from day 4 to day 30.
11.5 Cap: 10% of the delayed order value, and never more
     than the order value itself.
11.6 Escalation: delay beyond 30 days entitles Buyer to
     cancel the balance and buy replacement goods; Seller
     pays the documented price difference up to 15%.
11.7 Air freight: where delay is caused by Seller, Seller
     pays the difference between sea and air freight for
     the quantity required to protect the retail date.
11.8 Notice: Buyer must claim within 10 working days of
     the ship date, with evidence of the loss.
11.9 Exclusions: force majeure, Buyer-caused approval
     delay, and changes requested by Buyer after
     confirmation extend the ship date day for day.

Caps, Carve-Outs and the Force Majeure Habit

Two numbers decide whether a delay clause is credible: the daily rate and the cap. A rate that is too low is ignored, because paying it is cheaper than expediting. A rate that is too high invites the factory to sign and then price the risk back into the quotation. Half a percent per day with a ten percent cap is common because it is painful without being existential.

  • Deduct liquidated damages from the invoice rather than chasing a credit note; recovery rates are far higher.
  • Define on-time by readiness at the dock, not by the carrier's bill of lading, which the seller does not control.
  • Exclude delays caused by the buyer's late approval, late artwork or late trim cards, and say so explicitly.
  • Require force majeure notice within 5 working days with a recovery plan; a notice without a plan is an excuse.

Force majeure is the clause most often used to escape a delay that was simply a capacity failure. Narrow it: name the events, require contemporaneous evidence, and require the seller to allocate available output fairly among customers rather than to the loudest account.

Capacity, Allocation and the Seasonal Squeeze

Lead time collapses in the eight weeks before a season ships, when every customer wants the same slider finish. A contract that reserves capacity in units rather than in weeks protects the buyer far better. State a monthly volume band, the notice period required to change it, and what happens when demand exceeds the band. A seller who has promised 200,000 pieces a month and receives 320,000 will allocate, and the allocation will not favour the customer with the weakest clause.

Also separate standard lead time from expedited lead time. Expedited production costs money, and the contract should say who pays and how much notice is required. An expedite clause with no price attached is a request, not a right.

What Delay Actually Costs

The visible cost is air freight. The larger cost is the retail markdown when a style lands three weeks late, and the largest cost is the cancelled programme when a buyer loses confidence. A delay clause that recovers only the freight has recovered a fraction of the loss, which is why the escalation and cancellation rights matter more than the daily rate.

YCC's order confirmations state the ship date together with the inspection date and the document deadline, so a delay is visible at the inspection milestone rather than at the port. Buyers who monitor only the final date learn about problems when there is no longer time to fix them.

A Note on Use

This article is general commercial reference, not legal advice. Liquidated damages, penalty caps and cancellation rights are treated differently across jurisdictions, and in some they may be unenforceable or require a genuine pre-estimate of loss. Have qualified counsel review the clause before use.
