For Canadian brands with 50+ SKUs selling into the US

A tariff changed last week. Which of your products are affected?

Rules on Canadian goods entering the US have been moving repeatedly, and nothing tells you when a change touches your catalogue. TariffPulse maps every SKU to its current rate and emails you the day one of yours moves.

  • Every SKU mapped to its HS code and current US rate
  • Alerts the day a rate affecting your catalogue changes
  • Margin impact calculated per SKU before you find out from an invoice

Early access — we are onboarding a first cohort and reply to every enquiry within one business day.

The cost of finding out late

SKUs affected by a rate change14
Monthly US units across those SKUs620
Additional duty per unit$3.90
Unbudgeted duty per month−$2,418
Typical delay before you notice4–8 weeks

Illustrative. The delay is the variable that matters most — the per-unit amount is fixed, but how many units you ship before noticing is entirely a function of monitoring.

The problem

The news tells you a tariff changed. Nothing tells you whether it is yours.

Trade measures affecting Canadian goods have been announced, amended, delayed and partially rescinded repeatedly. Each announcement arrives as a policy headline covering categories of goods, not as a list of your SKUs.

Translating a headline into an answer means knowing the HS classification of every product you sell, reading the measure to find which headings it covers, and working out which of your variants fall inside. For a fifty-SKU catalogue that is a day of work. For a three-hundred-SKU catalogue nobody does it.

So you find out the way everyone finds out: a duty invoice comes in higher than expected, weeks after you shipped at the old price. By then you have sold a month of orders at a margin that no longer exists.

Is this you?

If three or more of these are true, TariffPulse will pay for itself. If none of them are, we will tell you so rather than sell you something.

How it works

Four steps, and you are only in one of them

The work happens whether or not you are watching. You get the output.

1

We map your catalogue to HS codes

Every SKU gets a classification with reasoning attached, so alerts are accurate rather than approximate. Existing codes are reviewed, not assumed correct.

2

Codes are watched against current US measures

General rates plus the additional measures currently applying to Canadian-origin goods, tracked at the heading and subheading level.

3

You get an alert when yours moves

Named SKUs, the old rate, the new rate, the effective date, and the monthly unit volume behind it.

4

Margin impact, not just news

Each alert includes what the change costs you per unit and per month, so you can reprice or pause rather than investigate.

What you get

Everything included

1

SKU-to-HS mapping with reasoning

Your catalogue classified and documented. This is the asset — alerts are only as good as the mapping underneath them.

2

Heading-level change detection

Measures are written against headings and subheadings, so monitoring has to work at that level rather than by product category.

3

Named-SKU alerts

Not "textiles may be affected." A list of your product names and variant SKUs.

4

Effective-date awareness

Changes are frequently announced with a future or retroactive effective date. The date is in the alert because it determines what you owe on goods in transit.

5

CUSMA interaction flagged

Whether a measure applies to goods claiming preferential treatment changes the answer entirely, and is where most confusion lives.

6

Margin impact per SKU

Unit volume times rate delta, so the alert arrives with a decision attached.

FAQ

Questions worth asking

How do I find out whether my product is on a tariff list?
You need two things: the HS classification of the product, and the text of the measure, which lists the headings and subheadings it covers. Then you check whether your classification falls inside that list. The reason this is hard in practice is that most ecommerce catalogues do not have reliable classifications for every SKU, so the first step fails before the second one starts.
What is the US tariff on Canadian goods right now?
There is no single answer, and anyone who gives you one is oversimplifying. The rate depends on the product’s classification, whether it qualifies for CUSMA preferential treatment, and which additional measures currently apply to that heading. Two products from the same factory can face completely different rates. TariffPulse answers it per SKU because that is the only level at which the question has an answer.
Can I just watch the news?
The news tells you a measure exists. It does not tell you which of your variants are inside it, what the effective date means for goods already in transit, or whether a CUSMA claim changes the outcome. The gap between the headline and the answer is the work.
What if my HS codes are wrong today?
Then monitoring them tells you nothing useful, which is why we review the classifications first rather than taking your existing codes at face value. A wrong code produces confidently wrong alerts.
Does this tell me what to do about a change?
It tells you which SKUs, what the rate delta is, and what it costs per month at your current volume. The decision — reprice, absorb, pause, re-source — is yours, but you make it with the numbers in front of you instead of after the fact.
How often do changes actually affect a catalogue?
More often than brands expect, and unevenly. Long quiet stretches punctuated by weeks where several headings move at once. The value of monitoring is concentrated in those weeks.
