That Sinking Feeling at the Port

You're tracking a shipment that's supposed to be in your warehouse. Instead, it's sitting at a port of entry with a hold on it and no clear answer as to why. Your freight forwarder is telling you to wait. Your supplier is blaming paperwork. Your operations team is telling you the production line needs those parts now.

This is the moment most importers wish they'd had a plan in place. And for a lot of businesses, it's also the moment they realize how little they understood about the customs process before this happened.

Shipment holds are one of the most common — and most disruptive — customs issues US importers face. They can stem from a classification discrepancy, a missing or inaccurate import document, a licensing issue, a prior disclosure, or a flagging system that CBP uses to pull shipments for closer examination. The cause matters, because the right response depends entirely on what triggered the hold in the first place.

Why Guessing Is the Wrong Move

The Risk of Responding Without Legal Guidance

When a shipment is held, there's pressure to resolve it fast. That pressure leads a lot of importers to respond to CBP inquiries without really understanding what they're responding to — and that can make the situation significantly worse.

CBP communicates through formal documents. A CF-28 is a Request for Information. A CF-29 is a Notice of Action. Neither of these is a suggestion. They're official agency communications that affect your legal rights and your compliance record, and how you respond — and when — matters in ways that aren't always obvious.

Customs lawyers know how to read these documents correctly, interpret what CBP is actually concerned about, and craft responses that address the agency's questions without inadvertently creating new ones. That distinction — between responding helpfully and responding in a way that escalates the inquiry — is one that legal experience makes.

Classification Disputes: More Common Than You'd Think

How HTS Codes Become Legal Battles

Every product imported into the United States needs to be classified under the Harmonized Tariff Schedule. That classification determines the duty rate, applicable trade remedies, and in some cases whether the product can be imported at all. Most importers handle this through their customs broker, which works fine — until CBP disagrees with the classification that's been used.

When CBP issues a ruling that reclassifies your product at a higher duty rate, or issues a Notice of Action challenging past entries, you have the right to protest that decision. But protests have a 180-day window from the date of liquidation, procedural requirements that must be met exactly, and a legal standard for what constitutes a valid argument. Miss the deadline or file a weak protest, and you've lost your chance to recover.

A tariff attorney handles these disputes as a core part of their practice. They know how to build a classification argument, what prior rulings and court decisions support your position, and how to engage with CBP at the administrative level. If a protest doesn't resolve it, they can also take the matter to the US Court of International Trade.

The Section 301 Problem Hasn't Gone Away

Additional Tariffs, Exclusions, and What You're Leaving on the Table

A lot of US importers are still paying elevated tariffs on goods from China and haven't fully audited whether exclusions apply to their products. The exclusion process has gone through multiple rounds of extensions and reinstatements, and keeping track of what's currently available — and what the application requirements are — is genuinely difficult to do without dedicated legal support.

Customs lawyers who specialize in trade compliance track exclusion availability as part of their ongoing work. They can review your product list, flag which categories have active exclusions, and handle the filings required to claim them. For companies with significant China-sourced inventory, that work often pays for itself quickly.

Beyond exclusions, there's also the question of first-sale valuation. Most importers declare the value of their goods based on the price paid to the middleman or trading company they buy from. But US customs law allows, in certain circumstances, for importers to declare value based on the manufacturer's original selling price — which is typically lower. A tariff lawyer can evaluate whether first-sale valuation is available for your supply chain and, if so, how to document and implement it properly.

When Prior Violations Are on the Table

Voluntary Disclosure and Penalty Mitigation

If your company has been misclassifying goods, under-declaring value, or otherwise making import errors — even unintentionally — there's a legal mechanism called prior disclosure that can significantly reduce your exposure. Filing a prior disclosure with CBP before the agency has initiated a formal investigation can limit penalties to no more than the unpaid duties, rather than the much higher civil penalty amounts CBP is authorized to assess.

This is a time-sensitive, procedure-heavy process. It requires customs lawyers who understand the specific criteria that qualify a disclosure, how to structure it correctly, and what documentation CBP expects to see. Filing a prior disclosure incorrectly can actually worsen your position rather than help it.

Setting Up Compliance That Scales

What a Customs Program Looks Like for Growing Importers

As businesses grow their import volumes, the compliance requirements grow with them. Classification decisions that were manageable when you were bringing in a few containers a year become significant legal exposure when you're running dozens. Recordkeeping that was easy to maintain manually becomes a liability when CBP asks to see five years of entry documentation.

Customs lawyers help growing importers build compliance infrastructure that matches their operational scale. That means written classification procedures, trained internal staff, regular third-party audits, and a clear process for handling CBP inquiries when they come in. The goal is to make compliance a routine business function rather than a crisis response capability.

It also means having a legal relationship in place before you need it urgently. The customs attorney you've worked with on classification guidance is far better positioned to help you in an enforcement situation than someone you're calling cold with a hold on your shipment.

Your Shipment Doesn't Have to Be the Wake-Up Call

A lot of companies only engage customs lawyers after something goes wrong — a hold, a penalty, an audit. But the ones that engage proactively are the ones that avoid most of those situations entirely. Customs compliance isn't a legal luxury. For any business that imports regularly, it's a core operational requirement.

Is your import operation as protected as it should be? Talk to a qualified customs lawyer about your current compliance posture. A single review could uncover savings, close off liability, and give you the confidence to grow your import business without looking over your shoulder.
