If a carrier, terminal or a large customer has asked your company to back a promise with a standby letter of credit or a demand guarantee, the request is not about financing a shipment. It is about security: a bank promising to pay a third party if you (or, less often, your customer) do not perform, decided purely on paperwork rather than on who was actually at fault. That is a different instrument from a commercial letter of credit financing the sale of the cargo itself, covered in our guide to letters of credit and document discrepancies, and it is a different problem from managing whether your own customers pay on time, covered in trade credit insurance and credit control for forwarders. This is about the security instrument itself: what it commits you to, how the two main types differ, and what to negotiate before your bank issues one or before you accept one from a counterparty.
Why a forwarder ends up dealing with one at all
Three situations come up repeatedly.
A carrier, airline or terminal wants security before extending credit. Ocean carriers, airlines and some terminal operators will open a running credit account for a forwarder only against collateral, because they are effectively lending freight charges between invoice and payment. The IATA Cargo Agency Program is the clearest documented example: IATA states plainly on its accreditation pages that a bank guarantee, among other accepted forms of financial security, will be requested once it has reviewed an agent's financial statements, with the specific form and amount varying by country and IATA's own assessment. A demand guarantee or standby letter of credit is one of the ways an agent satisfies that requirement.
A customer on a large project-cargo or EPC contract wants a performance guarantee. If your business is moving heavy-lift or project cargo under a contract with milestone deliveries, the owner or main contractor may require a guarantee that pays out if you fail to deliver, separate from and in addition to any liability insurance you carry. Our guide to freight forwarder insurance, E&O and cargo legal liability covers the insurance side of that risk; a performance guarantee is a contractual security instrument, not a policy, and the two are not substitutes for each other.
You require one from a shaky customer instead of extending open credit. The relationship can run the other way too. If a new or financially uncertain customer wants freight moved on credit terms you are not comfortable extending, asking them to have their own bank issue a standby letter of credit or demand guarantee in your favour shifts the payment risk from your receivables ledger onto their bank, which is a different kind of protection from the customer vetting and limit-setting our credit control guide walks through.
How the two instruments differ mechanically
Both a standby letter of credit and a demand guarantee are independent undertakings: the bank pays against a compliant presentation of documents, without investigating whether the underlying contract was actually breached. Where they differ is in which rulebook typically governs them and in the vocabulary each rulebook uses.
A standby letter of credit is usually issued subject to ISP98, the International Standby Practices published by the International Chamber of Commerce as ICC Publication No. 590 and developed under the Institute of International Banking Law and Practice, effective from 1 January 1999 and purpose-built for standby instruments. A standby can instead be issued subject to UCP 600, the ICC's rules written primarily for commercial documentary credits, which apply to standbys only "to the extent to which they may be applicable" and are correspondingly less detailed on standby-specific situations such as extend-or-pay requests. A demand guarantee, by contrast, is typically issued subject to URDG 758, the ICC's Uniform Rules for Demand Guarantees, which took effect on 1 July 2010 and use "guarantor" and "applicant" rather than the letter-of-credit vocabulary of "issuer" and "applicant". Which rule set actually applies is a matter of what the instrument text says, not of what the instrument is called, so confirm the governing rules are stated explicitly before assuming ISP98, UCP 600 or URDG 758 automatically applies.
A demand guarantee should also be kept distinct from a simple, or accessory, bank guarantee, sometimes called a suretyship. An accessory guarantee is legally tied to the underlying contract: the guarantor can usually raise the same defences the principal debtor could, and the beneficiary generally has to show the underlying obligation was actually breached before collecting. A demand guarantee under URDG 758 is deliberately not accessory in that way. URDG 758 states that the guarantor is not concerned with, and cannot be bound by, the terms of the underlying contract, and it further restricts what a compliant demand can require: a guarantee should not contain a condition other than a date or the lapse of a time period unless it also specifies a document to indicate compliance with that condition, and the guarantor disregards any condition that fails to specify such a document. In practice this means a well-drafted demand guarantee still requires paperwork, just paperwork the beneficiary itself supplies (typically a signed statement that the applicant is in default), rather than independent proof.
The instrument in one table
| Feature | Standby letter of credit | Demand guarantee | Simple (accessory) bank guarantee |
|---|---|---|---|
| Typical governing rules | ISP98 (ICC Publication 590), sometimes UCP 600 | URDG 758 (ICC Publication 758) | National civil or commercial law; no ICC rule set |
| Relationship to the underlying contract | Independent; bank examines documents only | Independent; bank examines documents only | Accessory; tied to whether the underlying obligation was actually breached |
| What triggers payment | A compliant documentary presentation (often a simple demand plus a statement of default) | A compliant demand, which URDG 758 requires to be tied to a specified document if any non-date condition is attached | Proof, or at least an arguable case, that the principal debtor defaulted |
| Where it is more common | United States and other jurisdictions where local law makes true demand guarantees harder to structure | Widely used internationally, especially in construction, project cargo and government tenders outside the US | Domestic transactions under civil-law suretyship rules |
The "pay first, argue later" character, and what it actually costs you
The independence principle behind both a standby letter of credit and a demand guarantee is what makes them valuable to a beneficiary and expensive to an applicant. If the beneficiary presents documents that comply on their face, the bank pays, even if the applicant believes the underlying claim is wrong, overstated or fraudulent (fraud is the narrow exception both ISP98 and URDG 758 recognise, and it is deliberately hard to prove on short notice). Disputing whether the demand was actually justified happens afterward, between the applicant and the beneficiary, or against the beneficiary in court, not before the bank pays out.
What that means practically for whoever is asked to have one issued: it is not a promise on paper. The issuing bank will not commit to paying out on your behalf without security of its own, which usually means the guarantee amount is counted against your borrowing facility, or the bank requires cash collateral, for as long as the instrument is live. A standby letter of credit or demand guarantee sitting on your bank line reduces what else that line can fund, working capital, other trade finance, a factoring facility, for the full face amount and the full validity period, whether or not it is ever drawn. That contingent liability is the real price, not a headline fee percentage, and it is worth walking through with your own bank before agreeing to any specific amount or duration.
What to negotiate before you agree to one
Whether your bank is issuing the instrument or a counterparty's bank is issuing one in your favour, the terms below are the ones worth pushing on, because a badly drafted instrument sits on a credit line, or exposes a beneficiary to a slow and one-sided claim, for far longer than the underlying risk justifies.
- Validity period. Fix an expiry date tied to the actual contract term or delivery milestone, not an open-ended one. Many standby letters of credit carry an "evergreen" clause that renews automatically unless the issuer gives notice, commonly with a defined notice window before each renewal date; confirm whether that clause exists and who has to act, and by when, to stop an unwanted renewal.
- A reducing, or step-down, amount tied to milestones. On a project-cargo contract with staged deliveries, there is no reason the full guarantee amount should stay exposed after early milestones are met and accepted. Negotiate a schedule that reduces the guaranteed amount as agreed deliverables are signed off, rather than one fixed figure that sits at full value until the contract closes out.
- Narrow, document-specific drawing conditions. Under URDG 758, a guarantee can require a signed statement of default without further proof, which is exactly the "pay first, argue later" risk described above. Push for the demand to require a specific, named document (a certified engineer's report, a specific notice already sent and acknowledged under the underlying contract) rather than a bare, unsupported statement, since that is the difference between a guarantee that is only drawn on genuine grounds and one that can be drawn on an assertion alone.
- Confirm the governing rules in the instrument text itself. Do not assume ISP98, UCP 600 or URDG 758 applies by default. State it explicitly, because the rule set decides how extend-or-pay requests, force majeure and document examination periods actually work, and those provisions differ between the three.
- Ask your bank what collateral or facility headroom the instrument actually consumes, and for how long, before agreeing to the amount a counterparty is asking for. A number that looks reasonable on the counterparty's term sheet can be a disproportionate draw on your own working capital line.
What to do next
If you are being asked to provide security for the first time, whether by a carrier opening a credit account, a terminal, or a customer on a large contract, start the conversation with your own bank's trade finance desk before agreeing to a figure or a duration, and get the governing rules and the drawing conditions in writing rather than relying on a verbal assurance about how it will be used. If you are on the other side, asking a customer's bank to back a shaky receivable with a demand guarantee, the same negotiating points apply in reverse: a validity period and drawing condition you actually understand are worth more than a headline guarantee amount you never expect to call.
Security instruments are one part of managing counterparty risk; finding a forwarder or a customer worth trusting in the first place is the other. You can search more than 29,300 logistics companies by country and service in the CargoLinked directory, or post a shipment on the public requests board and let forwarders with the right coverage come to you.
