Welcome back, last week we talked about the future of customs brokers since nowadays, most of the procedures are electronic, which means that almost anyone can start their own international trade procedures on their own. However, the expertise and trajectory of a custom broker are invaluable.
And talking about technology and commerce, in the actual eCommerce landscape, speed and efficiency are critical, especially for businesses that rely on express shipments and dropshipping models. As cross-border trade continues to grow, understanding special customs regimes becomes essential for ensuring fast delivery times, controlling costs, and maintaining legal compliance.
These regimes are designed to help customs brokers simplify customs procedures for low-value or high-frequency shipments, making them particularly relevant for express couriers and online sellers shipping directly to consumers.
For companies, special customs regimes can mean reduced paperwork, simplified declarations, and faster border clearance. However, they also come with specific eligibility criteria and compliance obligations that businesses must understand to avoid penalties.
That’s why our team of Mexican customs brokers has prepared this article. Here, we’ll break down how these customs regimes work, why they matter for express shipments and dropshipping, and what businesses should consider when using them to optimize their international shipping strategy.
What are special customs regimes?
Special customs regimes are legal frameworks that allow products to be imported, exported, or moved across borders under simplified or alternative customs procedures compared to standard import processes.
Their main purpose is to facilitate international trade by reducing administrative burdens, speeding up customs clearance. These regimes are particularly relevant in high-volume, time-sensitive logistics environments such as express shipments and eCommerce.
Unlike standard customs procedures, special customs regimes are designed to be more flexible and risk-based. Customs authorities apply them to specific categories of merchandise, shipment values, or economic operators that meet predefined criteria. This allows authorities to focus controls on higher-risk consignments while enabling faster processing for low-risk goods.

Special customs regimes for express shipments
Express shipments are built aroundspeed, reliability, and predictable delivery times, which makes traditional customs procedures a major bottleneck in cross-border logistics.
Special customs regimes are therefore essential because they adapt customs controls to the operational realities of express carriers, allowing high volumes of time-sensitive products to move quickly across borders without compromising regulatory oversight.
One of the key reasons these regimes matter is their reliance on risk-based and pre-arrival processing. Express carriers typically transmit shipment data electronically before merchandise reaches the destination country, enabling customs authorities to assess risks in advance. This approach significantly reduces clearance times and congestion at ports and airports.
Finally, these regimes create a more predictable regulatory environment for express shipments, which is crucial for customer satisfaction and supply chain planning. Faster and more consistent customs clearance leads to fewer delivery disruptions, clearer cost structures, and improved tracking accuracy.
Special customs regimes for dropshipping
Dropshipping relies on a supply chain in which goods are shipped directly from a supplier to the final customer. This model generates a high volume of low-value, individual shipments, making traditional customs procedures inefficient and costly.
Special customs regimes are therefore essential in enabling dropshipping operations to function at scale, as we mentioned above; by simplifying declarations, accelerating clearance, and adapting customs controls to the realities of eCommerce.
One of the main challenges in dropshipping is determining who is responsible for customs compliance. Special customs regimes often clarify or streamline this responsibility by allowing express carriers or platforms to act as intermediaries, submitting simplified declarations and handling duties and taxes on behalf of multiple parties.
In addition, special customs regimes increasingly rely on electronic pre-declaration and data sharing, especially in eCommerce contexts. Dropshipping platforms and express carriers often transmit shipment data to customs authorities before goods arrive in the destination country. This allows customs to perform risk assessments in advance, minimizing physical inspections and delays.

Taxes, duties, and VAT in special customs regimes
Special customs regimes do not eliminate taxes or duties, but they often modify how and when they are assessed and collected. For businesses using express shipments and dropshipping models, understanding these mechanisms is essential to avoid unexpected costs, ensure compliance, and set accurate pricing strategies across different markets.
How are duties calculated for express shipments?
Under special customs regimes, customs duties are typically calculated based on the customs value of the goods, their HS classification, and the applicable tariff rate in the destination country. As we mentioned, for express shipments, customs authorities may allow simplified valuation methods or consolidated declarations, especially for low-value consignments.
In many cases, express carriers act as intermediaries, calculating and advancing duties on behalf of the importer to ensure rapid delivery. These amounts are later recharged to the seller or the customer, sometimes along with additional handling or brokerage fees.
VAT/GST implications for dropshipping
Value-added tax (VAT) or goods and services tax (GST) is often the most complex tax element for dropshipping businesses operating under special customs regimes. In cross-border eCommerce, VAT/GST may be due at the point of import, at the point of sale, or through a simplified digital scheme, depending on local regulations.
Special customs regimes increasingly aim to shift tax collection to the transaction stage, particularly for low-value goods sold online. This means that VAT/GST obligations may arise even without a physical presence in the destination country.
In some jurisdictions, online sellers or platforms are required to register for VAT/GST, collect it from customers at checkout, and remit it to tax authorities. Failure to comply can result in delayed shipments, penalties, or platform restrictions.
Common tax compliance mistakes
One of the most frequent mistakes in special customs regimes is under-declaring the value of goods to reduce duties or taxes. While this may appear to lower costs in the short term, it exposes businesses to audits, retroactive tax assessments, and fines.
Another common issue is misalignment between sales data and customs declarations, particularly when automated systems are not properly synchronized.
Dropshipping businesses also often overlook country-specific VAT/GST rules, assuming that simplified regimes remove all tax obligations. In reality, these regimes streamline procedures but still require accurate reporting and timely payment.
In case you are interested in using these special customs regimes, you will not only need to establish clear tax responsibility, but we recommend that you work with knowledgeable logistics partners and customs brokers. Don’t hesitate to contact us, we’ll be happy to assist you.
