USMCA rules of origin can appear flexible when a product-specific rule connects tariff shift and regional value content with the word “or.” That flexibility exists at the finished-good level. It does not permit an importer or producer to combine selected elements from different origin alternatives component by component.
What “Or” Means in a USMCA Product-Specific Rule
The product-specific rules in Annex 4-B determine how a non-wholly obtained good may qualify as originating. Depending on the finished good’s tariff classification, the applicable rule may require a tariff shift, a regional value content calculation, or a combination of both.
Each Alternative Is a Complete Qualification Path
When a rule presents two alternatives separated by “or,” each alternative generally functions as an independent path to originating status. The producer may evaluate both paths and rely on the one the finished good fully satisfies. It may not create a third, blended path by applying one alternative to certain materials and another alternative to the remaining materials.
For example, a rule might provide:
- A specified change in tariff classification from any other heading, or
- A different tariff change, provided the finished good also satisfies a stated RVC threshold
Under that structure, the producer can qualify under the first alternative by demonstrating that every relevant non-originating material undergoes the required tariff shift. Alternatively, the producer can use the second path, but it must satisfy both the tariff shift and RVC conditions included in that path.
Qualification Occurs at the Finished-Good Level
The tariff classification, material origin, and value of individual components remain essential inputs. However, the legal conclusion applies to the finished good being exported and claimed as originating.
A producer therefore cannot designate Component A as qualifying through tariff shift while assigning Component B to RVC, then treat those separate outcomes as a combined origin determination. Instead, the producer tests the entire finished good against one complete alternative. If the first alternative fails because a non-originating material does not undergo the required classification change, the producer may test the finished good under another expressly permitted alternative.
This distinction is especially important for complex assemblies, kits, and goods incorporating significant content from outside the United States, Mexico, or Canada. North American assembly alone does not establish USMCA eligibility.
How to Evaluate Tariff Shift Before Using RVC
Tariff shift is often the first method evaluated because it can be less data intensive than regional value content. A successful tariff shift analysis still requires accurate classifications, defensible material-origin determinations, and a careful reading of the complete product-specific rule.
Classify the Finished Good and Its Materials
The analysis begins with the Harmonized Tariff Schedule classification of the finished good. That classification identifies the applicable rule of origin. The producer must then classify each non-originating material at the level required by the rule, such as chapter, heading, or subheading.
A standard tariff shift review generally follows this sequence:
- Confirm the finished good’s tariff classification.
- Identify the applicable product-specific rule.
- Establish which materials are originating and non-originating.
- Classify every relevant non-originating material.
- Compare those classifications with the required tariff change.
- Review any exceptions, notes, or additional conditions.
If all relevant non-originating materials undergo the specified change, the finished good may satisfy the tariff shift alternative, subject to the agreement’s other requirements.
Treat Unsupported Materials Conservatively
A supplier’s statement that a component was made in the United States, Mexico, or Canada is not necessarily sufficient to establish originating status. Country of manufacture and USMCA origin are different concepts. A material produced in North America may contain non-originating inputs and fail its own applicable origin rule.
Importers and producers should maintain corroborating support for materials treated as originating. Depending on the transaction, that support may include a USMCA certification, supplier origin analysis, bill of materials, production records, or other reliable documentation. Where adequate support is unavailable, the material generally should be treated as non-originating for the analysis.
If even one relevant non-originating material fails the required tariff shift, the first alternative may fail. The finished good can then be evaluated under an RVC alternative, but only if the applicable product-specific rule expressly permits it.
Using RVC Without Creating a Hybrid Origin Method
Regional value content can preserve eligibility when a finished good cannot satisfy a tariff-shift-only alternative. It measures the required level of regional value in the finished product, but it does not authorize selective treatment of components under separate qualification methods.
Apply One RVC Formula to the Finished Good
The USMCA generally provides transaction value and net cost methods for calculating RVC, subject to the wording of the applicable rule and any sector-specific requirements. Common thresholds may be expressed as 60 percent under the transaction value method or 50 percent under the net cost method, although the actual product-specific rule controls.
The basic concepts are:
- Transaction value method: regional content is measured using the adjusted transaction value of the finished good and the value of non-originating materials.
- Net cost method: regional content is measured using eligible net cost and the value of non-originating materials.
The calculation is performed for the finished good. The value and origin of components feed into that calculation, but individual components are not separately assigned to tariff shift or RVC qualification paths.
If an alternative requires both a tariff shift and RVC, the producer must satisfy both conditions. Passing the RVC threshold does not cure a failed tariff shift when that same alternative expressly requires the shift.
Preserve a Reproducible Origin File
An RVC determination should be supported by a controlled record that another qualified reviewer can reproduce. The file should typically include:
- The finished good’s classification and applicable origin rule
- A detailed bill of materials
- Material classifications and countries of origin
- Evidence supporting originating material status
- Values assigned to non-originating materials
- The selected RVC formula and threshold
- Cost records, adjustments, and calculation assumptions
- The analysis period and version history
Following the 2026 joint review, USMCA remains in force, with continued annual review activity expected. Preferential treatment remains commercially significant, particularly where non-qualifying goods face higher ordinary or additional tariffs. That environment makes disciplined origin governance more important, not less.
- USMCA remains in force after the July 2026 joint review (US declined a 16-year extension), with annual reviews now required through 2036 unless all parties agree to renew; qualifying goods continue to receive preferential (often duty-free) treatment, which has become more valuable amid additional 2025-2026 tariffs.*
- USTR opened a public comment period on October 5, 2026 (dockets USTR-2026-0595 and USTR-2026-0596) for the next joint review, with submissions due January 12, 2027, covering rules of origin, compliance, competitiveness, investment, and economic security; companies can flag issues with tariff shift, RVC, or related origin tests.
- Recent industry guides (October 2026) reconfirm that product-specific rules in Annex 4-B typically require a tariff shift, an RVC threshold (usually 60% transaction value or 50% net cost), or both for the finished good; origin is determined at the finished-good level, so mixed application of methods across individual components is not permitted.
- US-Mexico bilateral talks continued in 2026 with reported progress on autos, steel/aluminum, labor, and economic security (including potential tighter ROO to address non-North American content); Canada has faced additional tariffs, and commentators note that Chinese-origin kits or light assembly generally fail to meet USMCA ROO for US market access.
- Practitioner posts on X in early-to-mid November 2026 highlight the January 2027 comment deadline for rules-of-origin input, stress that goods must independently meet USMCA tests (tariff shift or RVC) to claim preference amid higher non-qualifying tariffs, and discuss risks of circumvention via Mexico or Canada.
Frequently Asked Questions
Can a Producer Use Tariff Shift for Some Components and RVC for Others?
No. The finished good must satisfy one complete alternative stated in the applicable product-specific rule. Component classifications, origins, and values are inputs to that analysis, but the producer cannot combine portions of separate alternatives to create a hybrid qualification method.
Can a Company Test Both Alternatives Before Making a Claim?
Yes. A producer may evaluate every alternative available under the applicable rule and select a complete method that the finished good satisfies. Testing multiple alternatives is prudent when classifications, supplier origin data, or material sourcing may change. The final claim should identify and support a defensible qualification path.
What Happens When One Material Fails the Tariff Shift?
If the rule requires every relevant non-originating material to undergo a specified tariff change, one failing material can prevent qualification under that alternative. The finished good may still qualify under a separate RVC or combined alternative if the product-specific rule provides one and all conditions of that alternative are met.
Is a USMCA Certification Required for Every North American Material?
Not necessarily in every circumstance, but the party making the claim needs reliable evidence supporting any material treated as originating. A manufacturing location or informal supplier statement does not establish USMCA origin by itself. Unsupported materials are generally best treated as non-originating until sufficient documentation is obtained.
Does Passing an RVC Threshold Automatically Establish USMCA Eligibility?
No. The finished good must satisfy the complete applicable rule and other relevant USMCA requirements. If the selected alternative requires both RVC and a tariff shift, both tests must be met. The importer must also possess valid claim support and retain the records necessary to substantiate preferential treatment.
Should Tariff Shift Always Be Tested First?
Tariff shift is commonly tested first because it may require less sensitive cost data and can be easier to administer. However, the best sequence depends on the product, sourcing model, available records, and rule language. Companies should use the method that is both permitted and adequately supported.
How Stable Software Can Help
