The broker files the entry, but the legal duty sits with the importer of record under the reasonable care standard. This post covers the three ways broker errors actually happen, what the importer liability means in practice, and the review routine that catches errors while they are still correctable.

## Reasonable care has a name and an address

Customs law in the US puts the obligation on the importer to exercise reasonable care in classification, valuation, and origin claims, and to keep the records to prove it. A broker acts as the importer agent with a power of attorney. When an entry is wrong, CBP looks to the importer first, and the importer remedy against the broker is a contract conversation that happens later, usually after the duty and any penalty have been settled with the government.

None of this makes brokers careless. It makes the importer the last line of review whether they planned to be or not, so the only choice is whether that review is a system or a surprise.

## The three real causes

Stale master data leads. The broker classifies and values from the product file they were given, and product files rot: a price renegotiated in March, a material swapped in June, a new supplier in a new country in September, none of it sent. The entry is a faithful filing of last year product.

Second, ambiguous instructions. A casual email saying use the usual code becomes the authority for a product the usual code never covered. Third, genuine keying and judgment errors by the broker, which happen in every high volume operation and are exactly what sampling review exists to catch. Notice the ratio: in most post incident reviews, two of the three causes live on the importer side of the fence.

## Corrections have clocks

Many errors can be fixed cleanly if caught early: post summary corrections before liquidation, protests after, within their windows. The same error caught years later, across hundreds of entries, is a prior disclosure conversation and a much larger cheque. The difference between a correction and a crisis is almost always the date it was found, which is why review frequency beats review depth. A shallow monthly sample finds things while they are still cheap.

## A review routine that fits in an afternoon

Pull a small sample of entries each month, spread across suppliers and product lines. For each, trace three fields back to source documents: classification against the current spec, value against the paid invoice, origin against the supplier declaration. Log mismatches, fix the master data the same week, and keep the log. That log, kept over years, is the physical evidence of reasonable care if the question is ever asked formally.

## Frequently asked questions

## If my broker made the error, am I still liable to customs?

Yes. The importer of record carries the legal duty of reasonable care, and the broker acts as your agent. You may have a contractual claim against the broker afterwards, but duty and penalties are assessed against the importer first.

## What is reasonable care in practice?

Being able to show you gave your broker correct, current information, that you sought advice where classification or value was uncertain, and that you reviewed entries for errors. A documented monthly sample review is strong practical evidence of it.

## How can a wrong entry be corrected?

Depends on timing. Before liquidation, a post summary correction handles many changes. After liquidation, a protest within its deadline is the route. Older or widespread errors may need a prior disclosure, which is a conversation to have with advice, early.

## How often should an importer audit its broker entries?

A small sample monthly beats a deep audit annually, because correction windows close with time. Trace classification, value, and origin to source documents, and fix the master data behind any mismatch the same week it is found.
