Is a commercial invoice required?

Yes. Customs authorities require a commercial invoice or equivalent for international shipments to determine duties and taxes. Requirements vary by country and cargo value; confirm with your customs broker before export.

Can I sign the invoice electronically?

Yes. Electronic signatures meet U.S. legal standards under ESIGN and UETA when intent, consent, attribution, and record retention are satisfied. Ensure the receiving customs broker and bank accept e-signed documents.

What if I discover an error after submission?

Correct errors promptly with an amended invoice or corrective documentation through your customs broker. Late corrections may trigger duty reassessments or fines and can delay release.

Which supporting documents are necessary?

Common attachments include packing lists, bills of lading, certificates of origin, and export licenses. The required set depends on the goods, origin rules, and customs demands for the shipment.

How long must I keep invoices?

Retain invoices per tax and customs rules—generally at least 3 years for tax purposes (IRC §6501(a)), longer if industry rules or audits apply, or if HIPAA records are involved.

Who must sign the invoice?

An authorized representative of the exporter or seller should sign. Authorization should be recorded; for e-signed documents keep an audit trail to demonstrate signer identity and intent.

What the Mexico Commercial Invoice Is and when it's used

A Mexico Commercial Invoice is a trade document that accompanies goods exported to or imported from Mexico. It itemizes the seller, buyer, description of goods, quantities, unit and total values, currency, country of origin, Harmonized System (HS) tariff codes, and terms of sale. Customs authorities use it to assess duties, taxes, and statistical imports; carriers, freight forwarders, insurers, and banks use it for routing, claims, and payment. Accurate invoices reduce clearance delays and support compliance with customs and import-export controls.

Why a correct Mexico Commercial Invoice matters

A complete and accurate commercial invoice supports timely customs clearance, correct duty and tax assessment, and valid insurance claims. It reduces the risk of secondary inspections, costly reclassification, and shipment holds that delay delivery and add expense.

Who prepares and relies on a Mexico Commercial Invoice

Multiple parties prepare, review, and use commercial invoices across the supply chain.

Exporters and sellers: Prepare and certify the invoice for customs and billing purposes; ensure HS codes and values are accurate.
Customs brokers and freight forwarders: Submit the invoice with customs entry to Mexican authorities and coordinate duties and clearance.
Importers and buyers: Use the invoice to pay duties, reconcile shipments, and support inventory and tax records.

Clear roles and accurate data among these participants make cross-border shipments faster and reduce compliance risk.
