U.S. tariff and customs rules can change with little notice. This article provides general educational information, not customs, tax, or legal advice; confirm each SKU’s HTS classification, country of origin, CUSMA eligibility, customs value, entry method, and duty treatment with a licensed customs broker or qualified customs or legal professional before shipping.
Canadian brands have dealt with several different U.S. tariff systems since March 2025. On July 24, 2026, the temporary 10% global surcharge ended, a separate 10% forced-labor Section 301 tariff took effect on most Canadian goods, and a new international-mail entry process began. Four days earlier, the United States announced separate 50% tariffs on listed Canadian goods that are scheduled to take effect on August 19.
That timing matters. A fulfillment plan based on a single headline rate can be wrong before the next replenishment reaches the border. The better operating question is: what will this SKU cost under its actual classification, origin, entry method, customs value, and inventory route?
What Canadian Brands Need to Know Now
Tariffs: The temporary 10% Section 122 surcharge applied from February 24 until 12:01 a.m. Eastern on July 24, 2026. A separate Section 301 action now adds 10% to most products of Canada, on top of the applicable HTSUS rate. Goods entered free of duty under CUSMA and specified product categories are excluded from that additional tariff. The USTR implementation notice controls the rate, exclusions, and July 24 effective date. Separately, the Section 338 announcement schedules a 50% tariff on listed Canadian goods from August 19 regardless of CUSMA status. Product scope and other trade remedies still need to be checked.
De minimis: Commercial shipments valued at $800 or less no longer receive duty-free Section 321 treatment merely because of their value. CBP says the suspension applies across all countries and transport modes, with narrow exceptions such as qualifying bona fide gifts and certain traveller goods. See the current CBP ecommerce guidance.
CUSMA: The July 1 joint review did not renew CUSMA in its current form, but the agreement remains in force while the parties continue discussions. Preferential treatment still depends on the product-specific origin rule and a valid claim. See the USTR joint-review statement.
Customs and brokerage: A tariff is only one cost. Entry preparation, bonds, CBP user fees, carrier charges, and broker fees are separate. Even when a broker files the entry, CBP says the importer of record remains responsible for the entry’s accuracy and applicable duties, taxes, and fees.
Inventory position: Moving replenishment into the United States can reduce repeated parcel-clearance work and keep U.S. returns domestic. It does not change the applicable tariff rate by itself, so compare the full per-order cost of Canadian parcel shipping with the full cost of bulk entry, U.S. storage, domestic delivery, and added inventory.
The immediate decision is to replace any company-wide tariff assumption with a SKU-level cost and origin matrix.
What Actually Changed: The Tariff Timeline That Matters
The sequence explains why invoices and models built only a few months ago may no longer be reliable:
- March 4, 2025: The United States began collecting an additional 25% IEEPA duty on most Canadian goods and 10% on Canadian energy products. The original rates and effective date appear in CBP’s Federal Register implementation notice.
- March 7, 2025: Canadian goods qualifying for duty-free treatment under CUSMA were excluded from the IEEPA Canada duty. The same amendment reduced the additional rate on non-qualifying potash to 10%, as recorded in the amended implementation notice.
- August 1, 2025: The additional IEEPA rate for non-CUSMA Canadian goods rose from 25% to 35%, while qualifying CUSMA goods remained excluded and Canadian energy and potash stayed at 10%. The July 31 White House fact sheet documents that change.
- August 29, 2025: The United States suspended duty-free de minimis treatment worldwide for commercial goods that had previously qualified under the $800 threshold. CBP’s suspension fact sheet confirms the date and worldwide scope.
- February 20 and 24, 2026: The White House ended the additional IEEPA ad valorem duties and introduced a separate 10% Section 122 surcharge, effective February 24 for no more than 150 days. Qualifying duty-free CUSMA goods were among its exceptions. The order ending the IEEPA tariff actions and the Section 122 proclamation are distinct actions.
- July 1, 2026: The three governments completed the first joint CUSMA review. The United States did not renew the agreement in its current form, but the USTR statement confirms that it remains in force while discussions continue.
- July 20, 2026: The United States announced three Section 338 tariff actions covering listed Canadian goods. The additional rate is 50%, applies to covered goods even when they qualify under CUSMA, and is scheduled to begin at 12:01 a.m. Eastern on August 19, 2026. Examples in the White House fact sheet include wine, hockey sticks, and cement. The annexes to the alcoholic-beverage, dairy, and motor-vehicle proclamations control the actual product scope. Each says the new duty is in addition to other duties except where the proclamation provides otherwise, so a covered SKU needs a fresh stacking and exclusion check before August 19.
- July 24, 2026: A separate forced-labor Section 301 action took effect. It adds 10% to most Canadian goods in addition to the applicable HTSUS rate. USTR’s legal notice excludes specified product categories and any Canadian product entered free of duty under CUSMA; heading 9903.05.29 and U.S. note 52 contain the controlling language. See the USTR fact sheet and implementation notice.
- July 24, 2026: The temporary Section 122 surcharge reached the end date in its Federal Register implementation notice. CBP’s new mail informal-entry process also took effect, replacing the interim postal-duty method with classification-based entry and duty calculation.
The operational decision is time-specific. Store the source and effective date beside every tariff assumption in the landed-cost file, then set a review date before the next import.
Why De Minimis Mattered More Than Most Brands Realized
The former $800 Section 321 treatment removed duty from many eligible direct-to-consumer parcels. It also let many low-value shipments move without the formal or informal entry process now required.
Consider a Vancouver apparel brand shipping 500 U.S. orders per day at a $60 average order value. Before August 29, 2025, an otherwise eligible order below $800 could receive duty-free de minimis treatment. Now the low value alone does not remove duty or entry obligations. The brand needs the correct classification, origin, value, entry method, and filer data for those orders.
There is no defensible fixed “after” cost per $60 order. CBP’s July 2026 ecommerce guidance says:
- Informal entry is generally available for eligible shipments valued at $2,500 or less.
- Formal entry is required above $2,500 and for certain goods, including goods subject to quotas or antidumping and countervailing duties.
- Under the new mail process, applicable duties depend on the HTSUS classification, country of origin, customs value, and other entry facts.
- Most mail shipments are exempt from the Merchandise Processing Fee, but other charges may apply. Inbound Express Mail Service is an exception to that general MPF treatment.
Carrier and broker charges are not tariffs and are not set at one government rate. CBP notes that brokers charge for their services, while duties and processing fees may be separate. Ask each carrier or broker for a written schedule by entry type, tariff line, disbursement method, bond, advancement, and return.
For a parcel model, calculate:
Applicable duty + CBP fees + brokerage/carrier clearance + transport + bond or disbursement cost + expected refusal/return cost
Then multiply by daily U.S. order volume. The decision is whether direct parcel entry still protects contribution margin after all six cost groups, not whether the order remains below $800.
CUSMA Compliance Is a SKU-Level Decision
CUSMA is still an important route to preferential tariff treatment, but “Made in Canada” is not a complete origin analysis. A good must meet the agreement’s applicable rule of origin and be supported by a valid preference claim.
For the Section 301 action effective July 24, that distinction has an immediate cost consequence: the additional 10% does not apply to a Canadian product entered free of duty under CUSMA. That exclusion does not remove an unrelated trade remedy that applies to the product, and it does not make a product CUSMA-eligible without the required origin support.
The USTR heading applies to “articles the product of Canada.” Shipping from a Canadian warehouse or buying from a Canadian seller does not establish origin on its own.
Start with classification. The HTS code points to the normal duty rate and the product-specific CUSMA rule. Origin analysis then tests the product and its materials against that rule. The result can differ across two products made in the same Canadian facility.
Apparel shows why the product detail matters. A knit T-shirt may fall in HTSUS heading 6109, but fibre content and construction determine the full classification. CBP’s current USMCA textile guidance says the revised rules for Chapters 61 and 62 include tariff-shift requirements and North American sourcing conditions for certain inputs, including sewing thread, pocketing fabric, narrow elastic bands, and coated fabric. A T-shirt cut and sewn in Canada from non-North-American fabric therefore needs the heading-specific rule and any applicable tariff-preference-level provision checked; Canadian sewing alone does not settle eligibility.
The certification process is more flexible than the old NAFTA form, but it still requires evidence. CBP says a USMCA certification has no prescribed form and must contain nine minimum data elements. U.S. regulations also require an importer claiming preference to retain supporting records for at least five years from importation. See 19 CFR Part 182.
Create one controlled record for every U.S.-bound SKU:
- Full 10-digit HTSUS classification and classification rationale
- Country of origin and supporting supplier data
- CUSMA product-specific origin rule and pass/fail conclusion
- Certification owner, issue date, blanket period if used, and supporting documents
- Normal duty rate and every additional trade action checked
- Importer of record, broker, entry type, and record-retention location
- Last verification date and named owner for the next check
The decision is made SKU by SKU. A mixed order or replenishment can contain goods with different duty treatment, even when every carton ships from Canada.
Three Fulfillment Strategies Canadian Brands Are Using Right Now
No inventory design removes the need for correct customs treatment. The difference is where entries happen, how often they happen, and whether individual customers or the brand feel the border friction.
1. Dual-Country Inventory With Domesticated Shipping
Inventory moves into the United States in planned replenishments. After customs release, U.S. ecommerce and wholesale orders ship domestically, while Canadian inventory continues to serve Canadian demand.
Consolidation can reduce the number of parcel entries, broker interactions, and cross-border return movements. It does not lower the tariff rate by itself, and it does not permit a brand to choose “wholesale value” simply because goods move in bulk. CBP’s valuation rules generally begin with the price actually paid or payable when merchandise is sold for export to the United States; other methods apply when transaction value is unavailable or unacceptable. See CBP’s customs-value guidance.
For a qualified brand, cross-border domesticated shipping can connect batch replenishment with domestic U.S. order delivery. The operational test is whether fewer entries, domestic last mile, and domestic returns offset the added storage, replenishment, and inventory-carrying cost.
2. A CUSMA-First Product and Sourcing Plan
This approach begins with the product file rather than the warehouse. The brand classifies its catalogue, tests each SKU against the applicable origin rule, closes evidence gaps with suppliers, and then assesses whether sourcing changes make commercial sense.
Do not change a supplier solely to chase a tariff preference. Compare the total change in component cost, lead time, minimum order quantity, quality control, and working capital with the verified duty difference. For fashion and apparel, fabric, yarn, thread, elastic, and other inputs can affect origin treatment.
The operational test is the annual, evidence-backed duty saving by SKU after the cost of sourcing and maintaining the claim.
3. U.S.-Only Fulfillment for U.S. Customers
This design moves the full U.S.-bound assortment into an American warehouse and replenishes it against a U.S. forecast. Customers receive domestic parcels and return goods to a domestic address.
It works when demand is predictable enough to avoid moving the same unit between countries to fix imbalances. The system must also show one real-time inventory position across ecommerce, wholesale, Amazon, and retail allocations. Evolution’s warehouse and inventory-visibility model illustrates the control brands need when stock is distributed across locations.
The operational test is whether the U.S. volume, service benefit, and return savings justify dedicated inventory and added operating obligations.
When Dual-Country Inventory or Domesticated Shipping Makes Sense
There is no universal U.S.-revenue threshold. Use an operating model built from your own orders.
Dual-country inventory deserves a full business case when several of these conditions are present:
- U.S. demand is steady by SKU, not driven by one brief campaign.
- Daily parcel clearance creates repeated entry, brokerage, support, or delivery work.
- U.S. customers are abandoning or refusing orders because charges or delivery timing are unclear.
- Return volume makes a second border movement expensive relative to domestic inspection and restocking.
- Wholesale, marketplace, or retail programs need U.S. inventory on a predictable schedule.
- The brand can fund safety stock in two countries without creating slow-moving inventory.
- The warehouse and order systems can allocate stock, prevent overselling, and report a single inventory picture.
Run the comparison over a full demand cycle:
Canada-direct parcel cost per U.S. order × U.S. orders
versus
Bulk entry + U.S. storage + domestic pick/pack + domestic delivery + inventory carrying cost + expected domestic return cost
Add a downside case for a tariff change and a demand miss. The right option protects margin in the base case without creating a cash or stock problem in the downside case.
What This Means for Your Landed Cost Calculation
Landed cost should be calculated at the SKU and entry level before it is rolled into an order average.
Use this structure:
Customs value
- normal HTSUS duty
- additional duties that apply to the product, origin, and entry date
− valid preferential or relief treatment claimed at entry
- CBP user fees when applicable
- broker, bond, carrier-clearance, and duty-advancement charges
- international or replenishment freight
- warehousing, pick/pack, and domestic or cross-border last mile
- expected return, refusal, redelivery, and inventory-carrying cost
For formal entries where it applies, the FY2026 Merchandise Processing Fee is 0.3464% of the entered value, with a $33.58 minimum and $651.50 maximum, plus a $4.03 surcharge for a manually filed entry. CBP publishes those current MPF amounts. USMCA-originating goods can receive an MPF exemption when the preference claim is made at entry; CBP’s USMCA entry guidance says an MPF refund is not available through a later post-importation claim.
For example, assume a July 24 or later entry has a $20,000 customs value. Under the USTR Section 301 implementation notice, that additional duty is $2,000 if the Canadian goods are covered and not excluded. If the goods are entered free of duty under CUSMA, that Section 301 amount is $0. The normal HTSUS duty and any unrelated trade remedies still need to be added or excluded on their own legal terms. An applicable MPF on the same $20,000 formal entry calculates to $69.28 before any other fee or private charge.
Use the U.S. International Trade Commission’s current Harmonized Tariff Schedule for the tariff line, then have the importer and broker confirm the entry treatment. Keep quoted broker and carrier charges in separate fields so a private service fee is never mistaken for government duty.
The decision is based on contribution margin after landed cost, not gross margin before customs and returns.
The Returns Problem Nobody Talks About
A return from a U.S. customer to Canada creates another international movement. It may require export evidence, Canadian re-entry documentation, transport, inspection, and a decision about whether the item can be resold. A return to U.S.-held inventory avoids that second border movement.
Duty drawback may help in some cases, but it should be treated as a recovery process rather than an assumed credit. U.S. rules allow up to 99% of certain duties, taxes, and fees on qualifying unused merchandise that is exported or destroyed, while rejected-merchandise and CUSMA claims have their own requirements and restrictions. See the CBP drawback overview and 19 CFR Part 190.
Model returns with four inputs:
- Return rate by SKU and reason
- Cost to move, inspect, and restock or dispose of each item
- Resale recovery in Canada versus the United States
- Drawback or returned-goods relief that a qualified professional has confirmed and the records can support
Evolution’s returns-management service can keep the physical workflow and inventory record connected. The location decision should follow the lowest verified net cost after recovery value, not an unsupported industry return-rate threshold.
How to Evaluate Whether Your Current Setup Still Works
Use this diagnostic with finance, ecommerce, operations, and your customs adviser:
Do you know the current U.S. contribution margin by SKU and channel? Include applicable duty, entry and broker charges, freight, fulfillment, last mile, payment cost, returns, and customer-service credits. An average that blends CUSMA-qualifying and non-qualifying goods can hide the SKUs causing the loss.
Is your classification and origin file ready before the order ships? Every active U.S.-bound SKU needs a classification rationale, origin evidence, preference decision, supporting certification where used, and last-verified date. If the team is deciding eligibility after CBP or the carrier asks, the process is reactive.
Who is the importer of record, and who pays charges without surprising the customer? Your Incoterm and sales terms should match the party actually prepared to clear the goods. The Government of Canada’s U.S. ecommerce logistics guide explains that Delivered Duty Paid places the transport, import, duty, and delivery responsibility on the seller. Whatever term you use, document the importer and customer-facing charge policy.
Would planned U.S. replenishment cost less than parcel-by-parcel border work? Compare both options with the same customs assumptions. Do not assign a lower tariff or customs value to bulk inventory unless your customs adviser has confirmed the treatment.
Can your inventory system support two countries? The team should see available, reserved, in-transit, quarantined, returned, and damaged stock by location. It should also prevent a promotion, wholesale allocation, or marketplace feed from selling the same unit twice.
What happens to a U.S. return? Decide the return address, inspection standard, disposition, inventory update, customer refund timing, export evidence, and any relief claim before the first return arrives.

What the 2026 CUSMA Review Means for Fulfillment Planning
The July 1 review did not end CUSMA. USTR states that the United States did not renew it in its current form, while also confirming that the agreement remains in force as the parties continue negotiations. Canada’s joint-review guidance explains that the review was not an expiry date and that the agreement remains in force until 2036 unless the parties extend or terminate it under its terms.
No current primary source verifies a final renegotiated outcome as of July 25. Do not model a new rule of origin, tariff preference, or renewal date until the three governments publish it.
The practical response is to keep documentation current, avoid inventory designs that depend on one tariff assumption, and make allocation rules adjustable by SKU and country. Add a formal customs-policy review before each major buy, product launch, and U.S. replenishment cycle.
Build a Fulfillment Plan That Can Change With the Rules
The tariff timeline will keep moving, but the operating method is stable: classify the product, prove origin, identify the importer, calculate full landed cost, and position inventory only after the numbers support it.
Evolution Fulfillment works as an extension of established multichannel brands, connecting inventory visibility, B2B and B2C fulfillment, returns, and cross-border domesticated shipping. That lets the operating plan change without separating customs decisions from warehouse and customer-experience decisions.
