For importers dealing in automotive parts, this agreement can significantly reduce landed costs and improve pricing competitiveness.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, the benefit only applies when <a href=\"https:\/\/clearit.ca\/canadian-customs-broker-blog\/the-most-imported-product-categories-in-canada-and-their-customs-requirements\/\">goods meet strict origin requirements<\/a>.

Unlike NAFTA, CUSMA includes a built-in <\/span><b>sunset mechanism under Article 34.7<\/b><span style=\"font-weight: 400;\">: the agreement expires after 16 years unless all three parties agree to extend it. The first <\/span><b>Joint Review is scheduled for July 2026<\/b><span style=\"font-weight: 400;\">, exactly six years after entry into force, and it will determine whether CUSMA continues as written, is renegotiated, or moves toward sunset in 2036.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For automotive parts importers, the 2026 review carries direct operational consequences.

However, eligibility is not based on product type alone, it depends on how and where the product is made.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Importers often assume that commonly traded parts automatically qualify, but that\u2019s not always the case.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Examples of automotive parts include:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Engine components\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Brake systems\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Suspension parts\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Electrical systems\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Lighting components\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Filters and consumables\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Interior accessories\u00a0<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Parts similar to <\/span><a href=\"https:\/\/clearit.ca\/canadian-customs-broker-blog\/importing-tools-and-hardware-into-canada\/\"><b>tools and hardware<\/b><\/a>, or integrated systems such as automotive electronics, may qualify, but only when the <span style=\"font-weight: 400;\">origin criteria are satisfied.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">The CUSMA Automotive Appendix: Core, Principal, and Complementary Parts<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The single most important regulatory text for automotive parts importers is the <\/span><a href=\"https:\/\/www.cbsa-asfc.gc.ca\/publications\/dm-md\/d11\/d11-5-17-eng.html\"><b>Appendix to Annex 4-B of CUSMA<\/b><\/a><span style=\"font-weight: 400;\">, commonly referred to as the <\/span><b>Automotive Appendix<\/b><span style=\"font-weight: 400;\">. This appendix establishes a three-tier classification system that determines which Regional Value Content threshold applies, whether tracing of non-originating materials is permitted, and how strictly origin must be substantiated.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Most importers are unaware that their parts fall into one of these tiers. CBSA, however, applies tier-specific rules during verification.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Core Parts (Strictest Origin Requirements)<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Core parts must qualify as originating with <\/span><b>no tracing allowed for non-originating materials<\/b><span style=\"font-weight: 400;\">.

Those who don\u2019t often face reassessments and penalties.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In today\u2019s enforcement-focused environment, CUSMA should be treated as a strategic tool, not a shortcut.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Frequently Asked Questions<\/span><\/h2>\n<h3><span style=\"font-weight: 400;\">Does shipping automotive parts from the U.S. mean they qualify under CUSMA?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">No. CUSMA eligibility is determined by <\/span><b>origin<\/b><span style=\"font-weight: 400;\">, not by shipping route. A part manufactured in China, shipped through Detroit, and re-exported to Canada does not qualify under CUSMA regardless of how many times it crosses the border. To qualify, the part must be either wholly obtained in Canada, the U.S., or Mexico, or sufficiently transformed within the CUSMA region under the Product-Specific Rules of Origin in <\/span><b>Annex 4-B<\/b><span style=\"font-weight: 400;\">. CBSA can reassess claims up to four years after import under CARM if origin cannot be substantiated.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">What is the Regional Value Content threshold for auto parts under CUSMA?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">RVC thresholds vary by part tier. <\/span><b>Core parts<\/b><span style=\"font-weight: 400;\"> (engines, transmissions, body\/chassis, axles, suspension, steering, advanced batteries) require 75% RVC under the Net Cost method with no tracing of non-originating materials permitted. <\/span><b>Principal parts<\/b><span style=\"font-weight: 400;\"> require 70% Net Cost or 80% Transaction Value RVC. <\/span><b>Complementary parts<\/b><span style=\"font-weight: 400;\"> require 65% Net Cost or 75% Transaction Value. Importers should calculate using the method most favourable to qualification but must apply it consistently across the certification period.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">What is the difference between Net Cost and Transaction Value methods?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">The <\/span><b>Net Cost method<\/b><span style=\"font-weight: 400;\"> calculates RVC based on total production cost minus sales promotion, royalties, shipping, and non-allowable interest, divided by net cost. The <\/span><b>Transaction Value method<\/b><span style=\"font-weight: 400;\"> uses the FOB-adjusted sale price as the denominator. Net Cost is mandatory for core auto parts and for related-party transactions. Transaction Value is generally simpler but produces lower RVC percentages, requiring higher thresholds. CBSA Memorandum D11-4-2 provides full calculation guidance.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">What is a CUSMA Certification of Origin and who can issue it?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">A Certification of Origin is the document supporting a CUSMA preference claim. Under <\/span><b>CUSMA Article 5.2<\/b><span style=\"font-weight: 400;\">, it must contain nine minimum data elements: certifier identity, exporter, producer, importer, HS classification to six digits, origin criterion, blanket period (if applicable), authorized signature with date, and a prescribed certification statement. Unlike NAFTA, CUSMA permits the <\/span><b>importer, exporter, or producer<\/b><span style=\"font-weight: 400;\"> to issue certification, and no fixed template is required. Certifications can cover a single shipment or a blanket period of up to 12 months.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">How does CARM affect CUSMA claims?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Since October 21, 2024, all CUSMA claims must be filed through the <\/span><b>CARM Client Portal<\/b><span style=\"font-weight: 400;\"> using the Commercial Accounting Declaration with the appropriate tariff treatment code (10 for U.S., 11 for Mexico). Importers must hold an active CARM account, post financial security electronically, and maintain digital records accessible through the portal. Tariff treatment code errors are now the leading cause of automated CUSMA rejections in CARM.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">What records must I keep for CUSMA imports?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">CBSA Memorandum D17-1-21 requires importers to retain all CUSMA-supporting records for <\/span><b>six years from the date of import<\/b><span style=\"font-weight: 400;\">. Records include the Certification of Origin, bills of materials with origin designation per component, production records, cost accounting records supporting RVC calculation, supplier declarations, component invoices, and tracing documentation for materials on the Annex 4-B Tracing List. Records must be available in English or French and must be producible within 30 days of a CBSA request.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Can CBSA reassess my CUSMA claim after the goods are released?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Yes. CBSA conducts CUSMA verifications through random sampling, risk-based selection, and the semi-annual <\/span><b>Trade Verification Priorities<\/b><span style=\"font-weight: 400;\">. HS Chapter 87 has appeared on the priorities list in recent cycles, indicating active enforcement focus on automotive imports. If non-compliance is identified, CBSA issues a Detailed Adjustment Statement reassessing duty, GST, and AMPS penalties, with a 90-day dispute window under Section 60 of the Customs Act.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Do I still pay GST on auto parts when CUSMA reduces duty to zero?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Yes. CUSMA only addresses <\/span><b>duty<\/b><span style=\"font-weight: 400;\">, not Goods and Services Tax. The 5% GST applies to the <\/span><b>value for tax<\/b><span style=\"font-weight: 400;\"> which equals the customs value plus any duty owing. Even at 0% duty, GST is calculated on the customs value alone.
