Caspian's classification advisory reviews your product catalog, identifies misclassified items, corrects duty exposure before it accumulates, and seeks CBP binding rulings when certainty matters most.
The Harmonized Tariff Schedule of the United States (HTSUS) contains over 17,000 product classifications. Each 10-digit HTS code carries a specific duty rate, a set of applicable trade agreements, potential Section 301 or Section 232 tariff overlays, and eligibility rules for programs like duty drawback and GSP.
Classification is simultaneously the most consequential and most error-prone part of the import process. Suppliers assign codes based on their own country's tariff schedule. Customs brokers file based on what they're given. Nobody systematically audits whether those codes reflect the actual legal classification of the merchandise under US customs law.
Caspian does. Classification advisory is proactive tariff mitigation: catching overpayments before they're made, not after.

Caspian's trade advisors conduct a systematic review of your product catalog against HTSUS classification rules, applying the General Rules of Interpretation (GRI), Section and Chapter Notes, and applicable CBP administrative rulings. Every item in your catalog is confirmed, corrected, or flagged for further review.
Duty rate optimization identifies items that are incorrectly classified at higher-duty HTS codes when a lower-duty classification is legally defensible. This is not aggressive tariff engineering. It is an accurate application of the tariff schedule. Getting the correct classification and the correct duty rate is a legal right, not a loophole.
With Section 301 tariffs, Section 232 tariffs, and IEEPA tariff actions creating duty rate differentials of 25% or more across closely related HTS codes, small classification differences now carry enormous financial consequences. Caspian maps your product catalog against current tariff action overlays and identifies where classification precision directly reduces your tariff exposure.
When classification is genuinely ambiguous, or when certainty matters for financial planning, contract pricing, or supply chain investment, Caspian prepares and submits CBP binding ruling requests on behalf of importers. A binding ruling from CBP's National Commodity Specialist Division provides legal certainty on how your merchandise will be classified at the border.
Many free trade agreements, including USMCA, KORUS, and CAFTA-DR, require specific HTS classifications to establish origin and claim preferential duty rates. Caspian reviews your classifications against applicable FTA rules of origin to confirm you're capturing every available duty preference.
CBP classification decisions evolve. New CBP rulings, court decisions, and tariff schedule amendments can change the correct classification of existing products. Caspian monitors regulatory developments and alerts you when a classification change affects your product catalog, before a CBP audit finds it.
HTS classification is the process of assigning the correct 10-digit Harmonized Tariff Schedule code to every product you import. The HTS code determines your duty rate, your trade program eligibility, and whether the product can legally enter the country. Get it right and you pay what you owe. Get it wrong and you either overpay duties for years or trigger CBP penalties; sometimes both.
Because the wrong HTS code costs money in two directions. Misclassify a product into a higher duty bracket and you overpay on every entry until someone catches it. Misclassify into a lower bracket and CBP can issue penalties for negligence or, if the misclassification is found to be intentional, fraud under 19 USC §1592. Importers are legally required to use reasonable care in classification, and that responsibility falls on the importer, not the broker.
Trade Audit is reactive. It scans entries you've already filed and finds duty you overpaid. Classification is proactive. It makes sure your products are coded correctly before they're entered, so the overpayment doesn't happen in the first place. The two work together: Classification prevents future errors, Trade Audit recovers money lost to past ones.
Licensed customs brokers in-house. Classification is part of Caspian's advisory practice, which layers onto the platform with human expertise where the work requires it. The brokers review your products, assign HTS codes, and document the rationale. This is the kind of reasonable-care record that protects you if CBP ever questions a classification.
Caspian's Dynamic Product Catalog updates in real time as your products and HTS codes change, so the classifications feeding into your filings stay current as your catalog evolves.
CBP can challenge a classification through a rate advance, a Notice of Action, or a formal ruling request. If the disagreement results in a rate advance after liquidation, the response is a Protest under 19 USC §1514. If it surfaces before liquidation, a PSC corrects it. Caspian files both PSCs and Protests, so disputes get handled on the platform without routing to outside counsel for the filing itself.
Sometimes. If your products are currently misclassified into a higher-duty code than the law requires. The goal of classification work isn't to find the lowest possible code; it's to find the correct code. When the correct code happens to carry a lower duty rate than the one currently being used, the savings are real and ongoing. Trade Audit will surface those opportunities; Classification work locks them in going forward.
