Urgent Alert: New Canada-US Duties Hit August 19th – What Shopify Merchants MUST Know About Tariff Changes

Hey Shopify fam! I've been spending some time in the community forums, and a really important discussion popped up that I absolutely need to bring to your attention. It's about some significant duty changes between Canada and the US, specifically kicking off on August 19th. If you're sourcing products from Canada for sale in the US, or vice versa, this is a must-read.

The Lowdown: A 50% Duty Jump on Canadian Goods

So, here's the core of it: The US has published three proclamations under Section 338, which means that from August 19th, an additional 50 percentage points of duty will apply to a whopping 554 Canadian tariff lines. And get this – qualifying under USMCA (that's the United States-Mexico-Canada Agreement) does not exempt them. That's a massive jump that could seriously impact your landed costs overnight.

One of our sharp community members, joshume, initially flagged this, highlighting that some specific headings (like 9903.03.12 to 9903.03.16) weren't even in the published schedule as of early on. This is a crucial detail because, as joshume pointed out, if these headings are still missing, any software (including what many brokers use!) that calculates rates from the schedule could come back with a number that looks complete but is actually 50 points short. Yikes!

Why 'Assuming by Product Type' is a Dangerous Game

My big takeaway from this community discussion, and something Mustafa_Ali emphasized, is that this isn't a simple 'all beauty products are taxed' or 'all food items are exempt' situation. This kind of arbitrary category split means you absolutely need to check line-by-line rather than just assuming based on a broad product type. It's a bit of a head-scratcher!

Joshume dove deep into the annexes and shared some eye-opening examples of just how arbitrary these boundaries look from a merchant's perspective:

• Honey is on the list, but maple syrup is not.
• Lip, eye, and nail make-up are on it, but a moisturizer is not. This means a beauty brand could have products in the same shipment that are half in scope and half out!
• Both cotton and man-made fiber sweatshirts are on the list.
• Upholstered wooden seats are not, but other furniture items are.

See what I mean? It's not intuitive, and it really drives home the point that you can't just glance at your product type and feel confident.

Your Action Plan: What to Do RIGHT NOW

Given the August 19th deadline is fast approaching, being proactive is key. Here's what you need to do, drawing directly from the expert advice shared in our community:

1. Contact Your Customs Broker or Freight Forwarder IMMEDIATELY

This is the most critical first step. Don't wait to find out at the border after August 19th. A 50-point duty jump can significantly alter your landed costs and, by extension, your customer-facing pricing.

2. Ask Them What They're Reading From

When you talk to your broker, don't just ask if your products are affected. Specifically ask them what source they are using to calculate these new duties. As joshume warned, if they're relying solely on a published schedule that might be missing the new headings (like 9903.03.12 to 9903.03.16), their calculation could be off by a significant margin. You need them to verify against the actual US proclamations under Section 338, not just a general schedule.

3. Review Your Product List Line-by-Line

Because of the arbitrary nature of the list, you or your broker need to go through your Canadian-origin products code by code. Don't assume that similar products will be treated the same way. A beauty brand shipping both makeup and moisturizer in the same order could genuinely have one taxed and one not.

4. Utilize Community Resources (with a Caveat!)

Joshume generously shared a free resource that lists the categories and codes, linked to a checker that takes 6, 8, or 10 digits:

This "Duty Diligence" page also links to the three Federal Register documents underneath it. It's a fantastic starting point for your research! However, joshume also added a crucial disclaimer: these lists were machine-read from scanned annexes, so you should always confirm any single line at the source before you act on it. Use it as a guide, but always verify with your broker and the official documents.

This is a significant change, and being prepared means getting ahead of it. Don't let these new duties catch you off guard and impact your margins. Reach out to your customs experts, dig into your product codes, and make sure you're fully aware of how this affects your Shopify business. If you have any Canadian-origin codes you want checked, joshume even offered to look them up in the thread, so don't hesitate to engage in the community!
