USMCA Regional Value Content: Net Cost Method Worked Examples and the 75% Line

Updated 2026-10-21. Formula text quoted from HTSUS General Note 11 (Rev. 21, 2026) and the Canadian CUSMA implementation regulations; every computation below is reproducible from the pinned inputs.

1. Two formulas, one statute

USMCA rules of origin live in HTSUS General Note 11. Subdivision (c)(i) lets the importer, exporter or producer choose between two computations:

TV is the transaction value adjusted to exclude international shipment costs; NC is the net cost of the good; VNM is the value of non-originating materials, including materials of undetermined origin, used by the producer. The numerator logic is identical — regional share minus foreign share over a base — but the bases differ, and the schedule's own wording flags the asymmetry that matters: subdivision (c)(v) removes the choice whenever the product-specific rule in subdivision (o) has no transaction-value test. That is why every automotive RVC story in this article is a net-cost story whether the importer likes it or not.

There is also a ratchet built into (c)(vi): if a verification forces an adjustment to transaction value or material values, the party may move from transaction value to net cost. Once net cost has produced a result, moving back is off the table. Pick your first method as if you will be stuck with it.

2. What comes out of the denominator

Subdivision (vii) defines net cost as total cost minus four categories, reachable through three alternative allocation paths: (A) subtract from the whole-facility total cost first, then allocate; (B) allocate total cost, then subtract what landed on the good; or (C) allocate each cost item so the exclusions never enter the good's pool in the first place. The four excluded categories are:

• sales promotion, marketing, and after-sales service costs;
• royalties;
• shipping and packing costs; and
• non-allowable interest costs.

VNM has its own fairness rule in (c)(iv): non-originating materials consumed to make an originating input you later use do not count against you — double-counting upstream foreign content is prohibited. Conversely a special rule lets certain local processing value embedded in non-originating components count as originating content, which is how regional fabrication of imported blanks earns credit.

3. Four worked examples

Example 1 reproduces the worked example in Canada's CUSMA Rules of Origin Regulations (SOR/2020-155, s.7); examples 2–4 are arithmetic on pinned inputs, recomputed by our generator at build time.

Example 4 deserves a second look because it is where audits concentrate. The same physical operation reports total cost of $800,000 with $200,000 of qualifying exclusions and $156,000 of non-originating materials. Presented naively against total cost the good shows 80.5% regional content; computed lawfully on net cost ($600,000) it shows 74.0% and fails the 75% line. Nothing about the factory changed — only the denominator did. The reverse presentation also occurs: heavy promotional spend inflates the benefit of exclusions, which is why subdivision (vii) offers three sanctioned paths and requires reasonable, consistent allocation rather than whichever figure flatters the filing.

4. The automotive ladder and averaging

Vehicles carry their own staging schedule inside the note: 66 percent under the net cost method beginning on July 1, 2020; 69 percent from 2021; 72 percent from 2022; and 75 percent under the net cost method beginning on July 1, 2023, and thereafter for passenger vehicles and light trucks. Parts listed in Table A.1 of the automotive appendix currently sit at 75% under net cost or 85% under transaction value, with high-value batteries (subheading 8507.60) called out separately. Producers may also aggregate RVC across a model year for intermediate-material super-cores — averaging that smooths month-to-month variance but binds you to the net-cost discipline all year.

Operationally, that means the 75% line is now the planning floor for anyone assembling vehicles or A-list parts inside North America. A component at 74.0% (example 4) is not a rounding error away from compliance; it is a supply-chain decision away — substitute one non-originating input, or push more qualifying processing into the region under the (c)(iv)(B) special rule.

5. Five checks before you certify origin

1. Read the product-specific rule first. If subdivision (o) for your good lacks a transaction-value option, the net cost method is mandatory — budget the accounting work before quoting FTA pricing via our FTA eligibility checker.
2. Lock the exclusion ledger. Promotions, royalties, shipping/packing and non-allowable interest must be traceable to the general ledger, or the three-path choice becomes an auditor's finding instead of yours.
3. Compute both methods anyway. Even where TV is lawful, net cost previews what a verification would force — and remember the one-way ratchet of (c)(vi).
4. Reconcile VNM against customs entries. Materials of undetermined origin count as non-originating; align the VNM workbook with entry data using our HS code reference so classification drift does not silently inflate regional content.
5. Document the allocation path. Whichever of (A), (B) or (C) you adopt, write it down and apply it consistently across the model year — switching paths between verifications is how arithmetic becomes testimony.

6. Frequently asked questions

What is the net cost method in USMCA?

One of two ways to compute regional value content. Under General Note 11 subdivision (c)(iii) of the HTSUS, RVC = ((NC - VNM)/NC) x 100, where NC is the net cost of the good and VNM is the value of non-originating materials used in production.

When must I use the net cost method instead of transaction value?

Whenever the product-specific rule in General Note 11 subdivision (o) provides an RVC requirement that is not based on the transaction value method. For those goods the choice disappears — subdivision (c)(v) makes net cost mandatory. Automotive goods are the largest such family.

Which costs are excluded from net cost?

Four categories come out of total cost: sales promotion, marketing, and after-sales service costs; royalties; shipping and packing costs; and non-allowable interest costs. The producer may remove them before allocation, allocate then subtract, or allocate each cost so they never enter the pool.

What is the RVC threshold for vehicles under USMCA?

It stages upward: 66 percent net-cost RVC from July 2020, 69 percent from July 2021, 72 percent from July 2022, and 75 percent from July 2023 onward for passenger vehicles and light trucks. Parts listed in Table A.1 face 75 percent under net cost or 85 percent under transaction value today.

Can I switch from transaction value to net cost after entry?

Yes in one direction only. If a verification forces a valuation or material-value adjustment, the importer, exporter or producer may recalculate using net cost. Once net cost has been used, switching back to transaction value is not permitted.

How do you calculate RVC step by step?

Subtract the four excluded cost categories from total cost to get net cost, divide the value of non-originating materials by that net cost, subtract the quotient from one, and multiply by 100. A good with $88 net cost and $40 of non-originating materials lands at (88-40)/88 = 54.5 percent.

Does the net cost method change what my product is made of?

No — it only changes the arithmetic used to prove it. Two factories can build identical goods and report different regional value content because their accounting presentation differs; the statute disciplines that presentation through three sanctioned allocation paths and a consistency requirement across verifications.

7. Recap

• Two statutory formulas exist; the net cost method, RVC = ((NC − VNM)/NC) × 100, is mandatory whenever the product-specific rule omits a transaction-value option.
• Net cost strips four cost categories from the denominator — and the stripping rules decide borderline cases, as the 80.5% vs 74.0% flip shows.
• For passenger vehicles and light trucks the net-cost requirement has staged to 75% since July 2023; Table A.1 parts face 75% (net cost) or 85% (transaction value).
• Method switching is one-directional: TV may collapse into net cost after a verification adjustment, never the reverse.
• Run candidate bills of material through the landed cost calculator, then confirm preference paperwork against our US FTA eligibility map and the Free-but-not-MFN census for the rate payoff.
