Every imported product is assigned an HTS code — and that code determines your duty rate, special tariffs, trade agreement eligibility, and regulatory requirements. One wrong digit costs money. GLCHB classifies goods correctly, every time.
Send us your product description and current HTS code. We'll review classification, check CBP rulings, and identify any savings opportunities — no obligation.

It is based on the international Harmonized System (HS) — a 6-digit global commodity classification maintained by the World Customs Organization (WCO) — with U.S.-specific detail added at the 8, 10, and occasionally deeper digit levels.
The HTSUS has 99 Chapters, organized into 22 Sections, covering everything from live animals (Chapter 1) to works of art (Chapter 97) and special classification provisions (Chapters 98 and 99). Classifying a product correctly requires understanding the product's essential character, the applicable section and chapter notes (which are legally binding), and the General Rules of Interpretation (GRI) that govern how ambiguous products are classified.
A complete U.S. HTS code is typically 10 digits. Here's what each segment means:
The first 6 digits (the HS number) are internationally recognized — all WCO member countries use the same first 6 digits for the same goods. The U.S. adds additional specificity at 8 and 10 digits, which can affect the duty rate, quota applicability, and statistical tracking.
CBP requires classification decisions to follow the GRI in sequence. Most goods are classified under GRI 1; the others apply only when GRI 1 doesn't resolve the question:
Since 2018, Section 301 tariffs on Chinese-origin goods have made HTS classification even more financially consequential. Section 301 tariffs are applied at the 8-digit or 10-digit HTSUS level — meaning the same physical product, classified differently, can face drastically different duty liability.
Consider engineered quartz countertops. They can potentially be classified under Chapter 25 (stone), Chapter 68 (articles of stone), or Chapter 69 (ceramic products), depending on composition and manufacturing process. Each chapter carries different Section 301 treatment. This is not a loophole — it's the product of genuine legal ambiguity that exists in the tariff schedule. CBP's published rulings and the WCO's Explanatory Notes inform the correct classification, and GLCHB reviews both before classifying high-stakes goods.
CBP has authority to penalize importers for classification errors it deems grossly negligent or fraudulent. Even innocent misclassification results in duty underpayment, which CBP can collect (with interest) up to 4 years after liquidation. Importers who discover a pattern of misclassification should consider a prior disclosure to CBP rather than waiting to be audited.
A CBP binding ruling (officially an "Advance Classification Ruling") is an official written determination from CBP stating how specific goods must be classified under the HTSUS. Once issued, the ruling is binding on all CBP ports of entry — a port cannot reclassify goods that are properly described in an active ruling.
GLCHB's process for binding rulings:
GLCHB also cross-checks the CROSS database for existing rulings on similar goods before every new commodity classification — to ensure our classification is consistent with CBP's own published guidance.
One of the highest-ROI services GLCHB provides is a reclassification audit for existing importers. Surprisingly often, goods have been classified under a higher-duty code for years — either through an original error or because the tariff schedule changed but the code didn't. Common savings mechanisms we identify:
| Savings Mechanism | How It Works | Typical Impact |
|---|---|---|
| Reclassification to lower-duty heading | Identify a more accurate heading with lower MFN duty rate | Varies; 0–15% on entry value |
| USMCA/CAFTA-DR preference | Claim preferential duty rate for qualifying goods from Mexico, Canada, or CAFTA-DR countries | Often duty-free (0% vs. 5–20%) |
| Chapter 98 special provisions | Duty-free or reduced duty for U.S. goods returned after processing abroad | Duty only on value added abroad |
| Section 301 exclusion claims | Identify active Section 301 exclusions from China tariffs for specific HTS codes | 25% savings on covered goods |
| First Sale valuation | Use first-sale (factory) price rather than middleman price as dutiable value | Typically 10–30% reduction in taxable value |
| Antidumping/CVD avoidance review | Verify product is correctly out-of-scope of an ADD/CVD order | Eliminate 30–400%+ ADD/CVD exposure |
In addition to duty rates, an HTS code determines which partner government agencies (PGAs) must review the shipment before CBP can release it. The most common PGAs for Miami-area importers include:
Accurate HTS classification is therefore not just a duty issue — it's a regulatory gatekeeping issue. An incorrect code that avoids a PGA requirement is a misclassification that creates compliance risk, not a smart shortcut.
Every shipment GLCHB handles goes through our classification workflow:
We maintain a commodity classification database for each client's regularly imported goods, so repeat shipments don't require starting from scratch. New vendors or product variations are reviewed against the existing classification to identify any material differences that would require re-analysis.
Send us your product description and we'll review classification, check CBP rulings, identify duty savings, and confirm PGA requirements — at no cost.
