HTS Classification for Codes That Hold Up

The 10-digit code you put on an entry decides your duty rate, your admissibility, and whether CBP comes back years later for back-duties. We classify your products correctly the first time, at the Otay Mesa and San Diego crossings, so the number holds up under audit.

What it is

What HTS Classification Actually Decides

Every product entering the United States has to be matched to a code in the Harmonized Tariff Schedule. That 10-digit number is not paperwork, it is the instruction that tells CBP how much duty you owe, whether Section 301 China tariffs or antidumping duties apply, and which agencies get to weigh in on your shipment. The importer of record is legally responsible for getting it right, even when a supplier or freight forwarder hands you a code to use.

Get it wrong and the exposure runs both directions. Classify too low and CBP can assess back-duties plus interest going back five years, along with penalties under 19 USC 1592 if they see negligence. Classify too high and you quietly overpay duty on every entry, money you rarely get back. A defensible classification, backed by the General Rules of Interpretation and the reasonable care standard, is what protects your margin and your record.

What’s included

  • Full 10-digit HTSUS classification grounded in the General Rules of Interpretation, section and chapter notes, not a guess off a product name
  • Duty rate and landed-cost analysis so you know the real number before the cargo moves
  • Section 301, antidumping, and countervailing duty screening on China and other flagged origins
  • Country of origin and substantial transformation review, which matters for IMMEX and Mexico-sourced goods
  • Review of supplier-provided or historical codes to catch misclassification before CBP does
  • Binding ruling requests filed with CBP when a classification is high-value, high-volume, or genuinely gray
  • Classification database for your recurring SKUs so every future entry stays consistent
  • Support for PGA-flagged goods where the code triggers FDA, USDA, or other agency review

How it works

How we handle it

Product review

We look at what the item actually is: composition, function, how it is packaged, and how it is used. Spec sheets, photos, and bills of material tell us more than a description line ever will.

Classification and duty analysis

We work the code through the General Rules of Interpretation and the chapter notes, then pull the duty rate and screen for 301, antidumping, and PGA flags so there are no surprises at entry.

Ruling when it counts

If the classification is gray, high-volume, or high-dollar, we file a binding ruling request with CBP so you have written certainty instead of an opinion that can be challenged.

Consistent filing going forward

We lock your SKUs into a classification record and apply the same codes on every ACE entry, so your history stays clean and audit-ready across both crossings.

HTS Classification FAQ

My supplier already gave me an HTS code. Isn’t that good enough?

No. The importer of record is legally responsible for the classification, not the supplier or the forwarder. Suppliers often pick a code that clears their export, not one that survives U.S. scrutiny. We review the code they gave you, and if it is wrong we correct it before it becomes your penalty.

What happens if CBP decides my code was wrong?

CBP can reliquidate entries and assess back-duties plus interest for up to five years. If they find negligence or gross negligence under 19 USC 1592, penalties can be several times the loss of duty. Correct classification and documented reasonable care are what keep you out of that exposure.

When is a binding ruling worth requesting?

When the classification is genuinely ambiguous, when the duty difference between two plausible codes is large, or when you import the same product in high volume. A binding ruling from CBP gives you a written, defensible answer you can rely on, which is far cheaper than defending a guess after the fact.

Can the right code lower my duty rate?

Sometimes, yes. Products often fit more than one heading, and the correct application of the General Rules of Interpretation can land you on a lower lawful rate. We do not stretch codes to dodge duty. We find the code that is both correct and, where the rules allow, the most favorable to you.

Do you handle classification for goods crossing at Otay Mesa from Mexico?

Yes. We classify U.S. imports coming north across Otay Mesa and San Diego every day, including IMMEX and maquiladora goods where country of origin and substantial transformation drive the analysis. Being border-native means we see how classification interacts with USMCA eligibility and PGA holds in real time.
