10 Critical Clauses Every Steel Purchase Contract Must Include

Most steel import disputes do not come from fraud — they come from silence. The price was right, the sample was right, but the contract never said who pays for re-inspection, what tolerance the walls carry, or what happens when the vessel misses laycan. A steel purchase contract is your only leverage once the goods are on the water, so the drafting is where the real negotiation happens. Here are the ten clauses that decide outcomes, with the specific numbers and wording that protect buyers.

1. Scope, Specification, and Governing Standard

Define the goods by standard + grade + delivery condition + dimensional schedule, not by name alone. “S355JR plate” is not a specification; “S355JR to EN 10025-2, normalized, 20 × 2440 × 12200 mm, EN 10029 Class A thickness tolerance, ED-Ex classifications” is. Attach a technical annex listing every item, quantity in metric tonnes, and the tolerance standard for each dimension. State that the technical annex prevails over the body in case of conflict — this single sentence resolves most document disputes.

2. Mill Certificates: Type and Traceability

Specify EN 10204 3.1 as the minimum, issued by the manufacturer, showing heat numbers, chemical analysis, mechanical test results, and heat treatment records — and state that heat numbers on certificates must match stenciling on the goods. For critical pressure-retaining or offshore work, buy 3.2 (independent witness by TPI). Require certificates in English, provided before shipment for document review, not stuffed into the courier pouch with the bill of lading.

3. Dimensional and Weight Tolerances

Reference the published tolerance tables explicitly: EN 10029 for plate, EN 10060/10055 for bright and black bar, API 5L / EN 10219-2 for pipe and hollow sections, ASTM A6/A20 for structural and pressure plate respectively. For quantity, fix the basis: theoretical weight (per standard density 7.85 and nominal dimensions) versus actual weighed — and remember theoretical weight of plate to Class A tolerance can under-deliver several percent versus buyer expectation. State the invoicing method; it changes your landed cost per part more than a 2% price concession does.

4. Price Basis, Incoterms, and Surcharges

Anchor the price: “USD 685/MT CIF Nhava Sheva, Incoterms 2020.” Then pin down what the price includes — beveling, bundle packaging, end protectors, marking, export docs — and what it excludes (duties, destination charges, demurrage). For contract periods longer than 30–60 days, agree how price adjustments work for raw-material movement (e.g. index-linked adjustment on billet/scrap indices) rather than leaving it to renegotiation under duress.

5. Payment Terms Structured to Match Risk

Common structures in steel export: 30% advance + 70% against B/L copy; or irrevocable L/C at sight for larger lots. If using L/C, scrub every document requirement against what the mill can actually produce — the most common loss scenario is a “discrepancy” fee cascade on documents nobody could satisfy (e.g. requiring SGS certificate when no TPI was booked). Add: buyer’s right to withhold final 5–10% payment until inspection at destination for repeat-trading relationships, but only if you actually want that friction.

6. Delivery Schedule and Liquidated Damages

Fix production lead time from receipt of advance or L/C, not from PO date — those differ by weeks. Define delivery as B/L date for CIF/CFR or dispatch date for FOB/EXW. Add liquidated damages that are enforceable and reasonable: e.g. 0.5% of delayed-lot value per week, capped at 5%, beyond which the buyer may cancel the undelivered balance. Without LDs, “delay” is unenforceable in most Chinese supplier contracts — with them, delay becomes rare.

7. Inspection Rights: Pre-Shipment and Destination

Three tiers, pick what matches risk: (1) final inspection before shipment — buyer or TPI (SGS, BV, TÜV, Intertek) verifies dimensions, surface, marking, and quantity against the annex; (2) witnessed testing — TPI witnesses tensile, UT, hydro; (3) destination inspection window — e.g. 30 days from discharge for claims on visible defects. State who bears TPI cost and that the goods remain inspectable in original packaging until claimed.

8. Quality Claims: Window, Evidence, and Remedies

A claims clause is worthless unless it defines evidence and remedy. Workable drafting: buyer notifies defects within 30 days (visible) / 90 days (latent, discovered in processing) with photos and test report; supplier option to (a) replace at supplier’s cost, (b) repair/rework, or (c) price-reduce proportionally; shipping on proven non-conforming goods back at supplier’s risk. Add the carve-out that MTC non-conformity (chemistry/mechanicals out of spec) is not a negotiable defect — replacement, full stop.

9. Packaging, Marking, and Documentation List

Steel ships well only when packaging is specified. State: bundles ≤ 5 MT (or as crane limits require), steel strapping with edge protection, end caps on machined ends, VCI or oiled protection for long transit, seaworthy export packing per the route. Fix marking: heat number, grade, size, PO number stenciled on each piece or bundle tag. Then list the complete document set: commercial invoice, packing list, B/L, certificate of origin (form as applicable), MTC, insurance certificate, and fumigation certificate if wood pallets are used. Missing-document delays at destination routinely cost more than the defects the documents are meant to prove.

10. Force Majeure, Disputes, and Governing Law

Define force majeure narrowly (government action, natural disaster, port closure) — “market price moved” is not force majeure, and mills will try to include raw-material crisis language. Require prompt notice within 7 days and the right to cancel after 30 days of FM. For disputes, prefer CIETAC arbitration in China for enforceability against Chinese assets, or Singapore/HK arbitration if you want neutrality; specify language of proceedings. This clause is the one you never want to use and the one that changes supplier behavior when they read it.

11. FAQ

Are the supplier’s standard terms (Proforma T&C) acceptable?

Read them — most exclude everything above. At minimum, attach your technical annex and claims clause and state they prevail; most mills accept this for repeat export business.

How much advance payment is safe?

With verified factories and 3.1 certs, 20–30% advance is normal. Above 50%, or for first-time suppliers, use L/C or third-party trade assurance rather than paying for hope.

What tolerance basis should I choose for plate?

EN 10029 Class A for general work, Class B/C where machining allowance matters — but then invoice on actual weight or agree theoretical weight with a fixed negative-mill margin.

Is destination inspection enforceable?

Yes, if the window (e.g. 30 days) and evidence standard (third-party report) are written in the contract and the supplier’s inspection rights at origin are respected.
