USMCA eligibility: what to check before claiming a preferential rate
Shipping from Mexico or Canada does not by itself prove USMCA eligibility. Establish the applicable origin rule and supporting production facts, then prepare the certification and claim correctly. A certificate is evidence of a claim, not a substitute for meeting the rule.
Start with the rule and the production facts
Identify the product classification and consult the relevant USMCA rule in the current HTS General Note 11. Products may qualify through different routes; do not apply a single regional-percentage shortcut to every product. Obtain supplier evidence about materials and production, and ask the broker which records support the specific rule.
Keep the shipping location, ordinary country-of-origin analysis and preferential originating status as separate worksheet questions. A warehouse address is evidence of shipment location, not of the manufacturing operations needed to meet an origin rule.
An evidence checklist for a Mexican supplier
| Supplier answer | What it establishes | Next question |
|---|---|---|
| We ship from Monterrey | Shipment location only | Where and how were the goods produced? |
| We manufacture the goods in Mexico | A production fact to investigate | Which product-specific rule is met, using which materials? |
| We can provide a certification | A proposed claim document | Does the evidence support the origin criterion and period? |
In this invented case, do not switch the estimate to a preferential rate until the unresolved questions are answered. Keep an ordinary-duty estimate as a planning baseline. Once eligibility is documented, compare the supported preference scenario while keeping customs value, quantities and entry date unchanged.
Check the certification without treating it as approval
USMCA does not prescribe a single mandatory certificate form. Annex 5-A specifies minimum data elements, including the certifier, importer/exporter/producer information as applicable, goods description and HS classification, origin criterion, period for a blanket certification, and the signed certification. Check the actual Annex requirements and exceptions with the broker; collecting names alone is not an eligibility review.
Archive the evidence used and date the review. If materials or manufacturing change, revisit the rule before reusing the claim. LandedLlama can model supported preference inputs, but it does not certify origin, issue a certificate or authorize a preferential entry.
Assumptions and limits
Assumptions
- Illustrative non-automotive purchase from a supplier in Mexico; no preferential status is assumed.
Costs and duties not included
- No tariff-shift or regional-value-content result is established for a particular product.
- A preference may not remove every additional measure or charge.
Prepare your own estimate
Use your shipment details to open the existing calculator.
Use digits and a dot, with up to two decimals (for example, 1200.50).
Opening the calculator prepares these inputs. Only pressing Calculate uses a calculation from your plan.
You will need to select the correct HTS code in the calculator before it can estimate duties.
Common questions
Are goods bought in Mexico automatically USMCA-originating?
No. Purchase and shipping location do not replace the applicable production and origin requirements.
Does a USMCA certificate guarantee the final total is zero?
No. Verify eligibility, the claim and separately applicable charges or additional measures for the product and date.
