Who answers for the number
Under US customs law the importer of record is expected to use reasonable care in classifying its goods, and that responsibility does not move to a customs broker simply because the broker filed the entry. Brokers often work from the descriptions and codes their clients give them, so a thin product description upstream tends to become a wrong classification downstream. CBP can question a classification at entry, during an audit, or well after the goods have been sold, and it can look across many entries at once. When it concludes the number was wrong, the questions become how much duty is owed and whether the importer acted carefully. That second question is where internal records about how the number was chosen carry real weight.
Why classifications drift
A classification is a conclusion about a specific article, and articles change. A switch in materials, a new function added by software, a change in how goods are packed into sets, or a move from finished goods to parts can send a product to a different heading. Companies with large catalogs often discover that similar items were classified differently by different people over the years. Additional duties tied to trade actions have made a single digit more expensive than it once was, and those measures have shifted repeatedly, so the duty effect of a classification should be checked against what is in force now. Keeping a record of each classification and the reasoning behind it, and revisiting it when a product changes, is usually cheaper than reconstructing it during an inquiry.
Picking the right correction
Bring product specifications, bills of materials, photos or samples, a sample of recent entries, and any rulings or broker advice you relied on. We compare the goods with the competing headings and look at what CBP has said about similar products in published rulings. From there the choice is usually among leaving the classification alone, asking CBP for a binding ruling before future imports, correcting recent entries where the timing still allows it, or considering a prior disclosure for past errors. Several of those routes depend on timing, and a prior disclosure generally loses its benefit once you know CBP has opened a formal investigation of the issue. We also talk about who in your organization should own classification decisions going forward.
