Surety Bond vs Cash Security Under CARM: Which Should Canadian Importers Post?
If your business imports into Canada, CBSA holds security against your account in exchange for letting you take delivery of goods before you pay the duties and taxes on them. You can provide that security in one of two ways, and the choice is worth real money.
A surety bond covers at least 50 percent of what CBSA calculates you need. A cash deposit has to cover 100 percent of it. The privileges you receive are identical. Only the capital commitment differs.
For a mid-sized importer, that difference runs to six figures sitting idle.
Why CBSA Asks for Security at All
Release Prior to Payment is the arrangement most Canadian importers run on without thinking about it. Goods arrive, CBSA releases them, and duties and taxes are settled on a monthly statement afterwards. Without RPP, nothing moves until the money clears.
CBSA takes financial security in return. It is a standing guarantee behind your account covering what you might owe in the gap between release and payment. It is not a duty, not a per-shipment deposit, and not a fee.
Two things changed with CARM, and both still catch importers out. Importers can no longer rely on their customs broker’s security; each business posts its own against its own business number. And CBSA now recalculates the required amount every year rather than leaving it set. If you want the background, what CARM changed for importers covers how the system fits together.
Start With the Number CBSA Calculates
Before the bond-or-cash question means anything, you need the figure both options are measured against.
CBSA takes the highest monthly accounts receivable balance on your account over the preceding 12 months, including duties and GST, and does it separately for each RM account on your business number.
Three things about that formula matter for the decision:
It is a peak, not an average. One large shipment or a seasonal build can set your requirement for the whole year.
GST is in the balance. Importers who think in duty terms consistently underestimate it, because GST on imported goods often exceeds the duty.
Each RM account is calculated on its own, with its own minimum. A business with several RM extensions faces several separate postings.
The full method, including the floor and the cap, is set out in this guide to how CBSA calculates the requirement.
The 50 Percent Rule Is the Whole Decision
Here is where the two instruments separate.
| Surety bond (written security agreement) | Cash deposit (security deposit) | |
|---|---|---|
| Share of the calculated requirement | At least 50 percent | 100 percent |
| Minimum | CAD $5,000 per RM account | No separate minimum published |
| Maximum | CAD $10 million per RM account | CAD $10 million per RM account |
| What it costs you | An annual premium | The full amount, held by CBSA |
| Where it comes from | A financial security provider | Your own bank balance |
A written security agreement is issued by a financial security provider. CBSA identifies these as insurers registered with provincial or territorial authorities, members of Payments Canada, and credit unions. You obtain the agreement and post it in the CARM Client Portal.
A security deposit is your own money, transferred to CBSA and held as a guarantee against importer debt.
What the Difference Looks Like
Illustrative figures. Yours come from your own portal.
| Highest monthly accounts receivable | Post as a bond | Post as cash | Capital difference |
|---|---|---|---|
| $8,000 | $5,000 (the floor applies) | $8,000 | $3,000 |
| $200,000 | $100,000 | $200,000 | $100,000 |
| $640,000 | $320,000 | $640,000 | $320,000 |
On the middle row, choosing cash means $200,000 of working capital sits with CBSA rather than $100,000 of coverage you rent for a premium. That capital is not earning anything, is not available for inventory, and is not reducing your operating line.
The top row shows the floor at work. Half of $8,000 is $4,000, but a security agreement cannot go below CAD $5,000 per RM account.
When Cash Still Makes Sense
The bond is not automatically right, and a guide that says otherwise is selling something.
Cash is worth considering when your calculated requirement is small enough that the gap is trivial. On an $8,000 requirement, the difference is $3,000, and some businesses would rather not carry a provider relationship for that.
It also suits businesses that cannot obtain a security agreement on reasonable terms. Providers underwrite. A young company, a thin balance sheet, or an adverse credit history can mean a premium that does not justify itself, or a demand for collateral that defeats the purpose.
And it suits importers winding down Canadian operations, where a short remaining horizon makes an annual instrument awkward.
For everyone else, particularly growing importers whose requirement climbs each year, the bond is the instrument that does not consume the capital you need to grow.
The Number Changes Every Year
This is the part businesses miss, because the first posting feels like a one-time task.
CBSA runs an annual review. The assessment period runs from October 20 of one year to October 19 of the next, and that window is what gets measured for your highest monthly balance. The recalculated requirement is communicated through the CARM Client Portal, with a compliance deadline in January.
Three details make this harder than it sounds:
The notification goes to the importer, not to your broker or your surety provider. If nobody is watching portal notifications, you will not know.
Only importers whose requirement increased get notified. Silence means your number held, not that no review happened.
Processing takes time. Paper endorsements have been reported at around 25 business days. A request started the week before the deadline may not land.
Confirm the exact dates for the current cycle in your own portal. The notification is the authoritative statement of what you owe and by when.
What Happens If You Fall Short
CBSA suspends Release Prior to Payment.
Duties and taxes then become payable before your goods are released. For a business importing weekly, that is an immediate cash and delivery problem, and it arrives without a penalty notice or duty assessment attached, which is exactly why it catches people unprepared.
The fix is not complicated, but it is not instant either, and shipments wait while it is sorted out.
A Short Checklist
- Pull your current calculated requirement and posted amount from the CARM Client Portal. If you cannot see them, fix your portal access first.
- Check each RM account separately.
- Look at your last 12 months for an outlier month driving the number.
- Work out the capital difference between 50 percent and 100 percent on your figure, and treat it as a treasury decision rather than a compliance one.
- Name someone responsible for monitoring portal notifications.
- Start any change weeks ahead of the deadline, not days.
The instrument you posted during the CARM transition was often whatever was quickest at the time. It is worth asking whether it is still the right one.
