International trade experts
When customs or tax authorities challenge the tariff classification, origin, or value of your goods, what is at stake is a tax assessment and often the viability of the operation itself. BG Consulting Group substantiates the grievances raised in legal defense with technical opinions in foreign trade and customs matters, and issues expert opinions when a case requires legal certainty before the corresponding authority.
What is the authority challenging?
Four questions to identify the type of expert opinion or technical support your case needs.

Situations we handle
Authority reclassifies your tariff code
Customs or an audit reassigns a tariff classification, changing the duty rate, the non-tariff regulations that apply, or access to preferential treatment. Disputing it takes more than a commercial argument: it requires technical support justifying the classification under the General Rules of Interpretation.
Origin denied, preference lost
The authority rejects the declared origin under the USMCA or another treaty and demands the duties that were waived under preference. Defending it means proving the specific rules of origin, the supporting documentation, and the criteria that apply to the goods.
Customs value questioned
The authority rejects the declared value or adjusts the taxable base through its own appraisal, raising the duties and taxes owed and potentially triggering penalties. Holding the declared value requires a technical valuation grounded in the customs valuation methods.
Annex 24 and IMMEX inconsistencies
Companies under an IMMEX program face findings on the Annex 24 inventory control system, unsupported discharges, or discrepancies in the material balance that put the temporary regime at risk and open the door to assessments on goods not returned.

International trade operations, from origin to destinationFrequently asked questions
Advice guides day-to-day operations. An expert opinion is a technical document that analyzes a specific case and is offered as evidence before the authority or court to support the defense grievances. It is prepared with the rigor and legal grounding its use within a proceeding demands.
From technical analysis to a grounded expert opinion.
When the authority challenges classification, origin, or the value of goods, or when legal certainty is needed before acting, the expert opinion moves through these stages until it is ready to be used as evidence.
Case review
We analyze the authority's act: the reclassification, the origin denial, the value adjustment, or the Annex 24 findings. This review determines the scope of the opinion and the technical criteria applicable to the specific case.
