Adapting to Trade Whiplash

Patrick Frith, Business Development Director at Avalara on how courier and postal networks can thrive in 2026.

The rules of international shipping are being rewritten — again. In 2026, postal and courier networks face a new wave of customs, tariffs, and trade compliance challenges that threaten to disrupt global delivery models built on speed and scale. From the European Union’s elimination of its low-value duty exemption to legal shifts in U.S. tariff enforcement and expanded customs scrutiny in North America, the changes affect every link in the supply chain.

But with complexity comes opportunity. For carriers ready to embrace compliance as a differentiator, these shifts are an opening to redefine their role — from delivery enablers to trade facilitators. Those who modernize customs workflows, provide landed cost transparency, and integrate compliance tools directly into ecommerce logistics will help their customers thrive, while unlocking new revenue and loyalty in the process.

New Customs Realities: Compliance Starts Before Pickup

Traditionally, customs clearance occurred at the border — a reactive checkpoint before parcels were released for delivery. In today’s trade environment, customs has moved upstream. Authorities in the U.S., Canada, and Mexico are increasingly demanding shipment data before arrival, including full tariff classification, origin documentation, and increasingly, declarations tied to ESG criteria such as forced labour or environmental footprint.

According to Maersk, 2026 will bring “continuous, multi‑regulation demands across your supply chain,” making compliance a responsibility not just of the importer, but of everyone involved in transport and fulfilment (Serra). What once required a customs broker now requires integrated, end‑to‑end capabilities.

For carriers, this means pre-arrival data must be collected and validated early, often at the point of label generation or checkout. It also means partnering more closely with shippers to ensure they are equipped to meet rising documentation standards.

EU’s de minimis elimination: The end of low‑value simplicity

One of the most impactful policy shifts in 2026 is the European Union’s decision to end its €150 de minimis threshold, effective March. Currently, parcels valued under that amount can enter the EU without paying customs duties, significantly reducing friction for direct‑to‑consumer sellers shipping from the U.S., China, and other non‑member countries.

That exemption is disappearing — and with it, the idea that small parcels can skip customs entirely.

Every parcel, regardless of value, will now require full tariff classification, declared origin, and proper valuation. The impact is enormous. Ecommerce platforms relying on simplified low‑value shipping must now support full customs compliance. Parcel carriers must ensure their systems and customer integrations can support these new requirements — or risk parcel rejections, delivery delays, and reputational damage.

While this increases friction in the short term, it also creates a more level playing field. Sellers who previously avoided duties via creative under‑declaration or abuse of low‑value thresholds will now face the same scrutiny as established exporters. Carriers who support their clients through the transition will gain trust — and market share.

U.S. IEEPA Case: The Legal Foundation of Future Tariffs Is in Question

A lesser known but highly consequential legal development could upend how tariffs are imposed in the U.S. In 2025, the Supreme Court agreed to hear a case concerning the scope of the International Emergency Economic Powers Act (IEEPA) — the same authority used to impose tariffs on Chinese goods during the Trump administration.

At issue is whether the executive branch has too much latitude to impose tariffs without congressional oversight. A ruling that limits presidential power under IEEPA could significantly alter how and when new tariffs are enacted. Instead of fast-moving tariff actions, the U.S. might face a slower, more legislative process or a surge in policy volatility as power shifts between branches.

For carriers, the implications are clear. The legal tools that shape tariff landscapes may change dramatically, and systems built to assume regulatory continuity may need a rethink. Staying informed and equipped to update classification and compliance logic in real time is no longer optional. It’s operational risk management.

Tariffs in 2025: Lasting Impacts on Trade Flows

This past year saw a surge in tariff activity across key trade lanes:

• Expanded U.S. Section 232 and Section 301 tariffs targeted sectors from steel and aluminum to consumer electronics, semiconductors, and automotive components.
• Environmental and social compliance measures emerged as enforcement mechanisms for trade agreements, with forced labour rules now applying to customs entries in both the U.S. and Canada.
• North American customs reforms focused on data timeliness and accuracy, aligning with EU approaches to pre-clearance and digital documentation.

As Maersk notes, trade compliance is no longer just about duties — “it encompasses a growing number of regulatory expectations that must be met to move goods smoothly” (Serra). This shift from tariff enforcement to comprehensive trade regulation means carriers need tools that do more than calculate percentages — they must manage documentation, evidence, and certification across multiple axes of risk.

The Cost of Compliance and the Risk of Delay

What’s the consequence of not keeping up? For ecommerce shipments, the risks include rejected customs entries, delayed deliveries, frustrated customers, and higher return rates. For B2B trade, non-compliance can lead to denied entry, vendor disputes, or loss of preferred importer status.

The costs are real:

• A single misclassified product can result in duty overpayments or underpayments.
• Late filings or missing origin certificates can mean penalties, retroactive duties, or blacklisting from trade preference programs.
• Consumers experiencing surprise duties on delivery often abandon future purchases.

This is not a future problem. It’s already happening and accelerating.

Strategic Playbook: 4 Ways to Lead, Not Languish

To navigate the complexity of 2026, carriers should focus on four high-impact strategies:

1. Digitize customs clearance

Manual customs processing is no longer viable at scale. Deploy automation tools that support:

• HS code assignment
• Duty and VAT calculation
• Digital declarations and e-document integration

2. Enable landed cost transparency

Surprise fees kill conversion rates. Offer Delivered Duty Paid (DDP) options and display total costs upfront, including duties, VAT, and brokerage.

3. Monitor trade regulations in real time

Laws are shifting faster than ever. Use compliance content engines that automatically update classification rules and duty rates across jurisdictions.

4. Position yourself as a compliance ally to merchants

Offer more than delivery, offer support. Help ecommerce and B2B sellers stay compliant, avoid risk, and win customer trust in the process.

Conclusion: From carrier to compliance orchestrator

Trade is no longer just about moving goods. It’s about navigating rules, managing data, and proving compliance every step of the way.

In this new landscape, postal and parcel networks must evolve from being fast and cheap to being trusted and compliant. Carriers that embrace this role will not only preserve their margins but also grow through new services and stronger customer relationships.
