COMPLETION OF YOUR BLANKET NAFTA CERTIFICATION

Preparation of the Certificate of Origin (CBP form 434) imposes certain legal obligations and liabilities
on the party signing the certificate and should be based on a careful inquiry into the terms of NAFTA and substantiation
that any goods you are seeking NAFTA preferential treatment for are, in fact, considered “originating” as defined by NAFTA.
The facts asserted in the Certificate must be supported by adequate records pertaining to the good, its materials and production.
The person signing the Certificate must be a knowledgeable and responsible person with authority to obligate the exporter/producer.

False statements of eligibility made in connection with a NAFTA claim may result in the denial of the claim and assessments of penalties as
provided by law. For goods covered by a blanket certification, it is the exporter’s responsibility to advise the importer of any significant
changes in the sourcing or production of a good that may affect the NAFTA claim. An importer who receives information that a certificate is
inaccurate or invalid must make a corrected declaration of origin within 30 days of discovery. Failure to correct a declaration that is
known to contain inaccurate information may result in the assessment of penalties.

Field-by-field instructions are found in the NAFTA Certificate Form Package. Certificates are valid only if properly completed, signed, and dated,
and cover only those products specified in field 5 of the form. A Certificate that contains inadequate information, is unsigned, or is otherwise
defective in its preparation is considered invalid and a NAFTA claim will be denied.

Please ensure that your completed Certificate does not contain some of these common errors/omissions that cause it to be invalid:

• Certificate not signed or dated.

• Date of blanket period or signing does not cover importation date or is in improper format. (day/month/year is correct format)

• Full legal name, tax ID#, & physical address of the applicable party(s) not shown in fields 1, 3, & 4* (*if field 4 is “various” does not need to be shown)

• Full description as invoiced not provided in field 5 (note- descriptions such as “parts of “or “articles of” are too general to allow CBP to relate
invoice items to the NAFTA certification).

• Field 6 requires a valid HS tariff classification up to the 6th digit. Whenever possible show the 10 digit tariff classification to ensure accurate entry processing.

• Carefully review the field instructions for NAFTA criteria on the back of the Certificate before completing field 7.

• Carefully review the field instructions on the back of the Certificate for the appropriate responses to be shown in fields 8, 9, & 10. Only those responses listed by CBP in the instructions are acceptable.

• Ensure that all boxes in field 11 (11a, 11b, 11c, 11d, 11e, & 11f) are accurately and fully completed to include the number of pages the Certificate consists of.
