The Harmonized System (HS) code is a standardized numerical method used worldwide to classify traded products. Incorrect classification can result in delayed shipments, overpaid or underpaid duties, compliance violations, and even product seizure. Here are the five most common mistakes exporters make when classifying their products.
Mistake 1: Using an Outdated HS Code
The World Customs Organization updates the HS nomenclature every five years. Many exporters continue using codes from previous editions that no longer apply. Always verify that you are using the current version of the HS code schedule, especially for technologically advanced products.
Mistake 2: Classifying by Product Name Rather Than Composition
A common error is to classify a product based on its commercial name rather than its composition or function. For example, a "vitamin drink" may be classified as a food supplement or a beverage depending on its actual ingredients and concentration. Always follow the General Interpretative Rules (GIR) of the HS system.
Mistake 3: Ignoring Country-Specific Classification Rules
Different countries may apply different classification rules for the same product. For instance, Saudi Arabia's SABER platform has specific requirements tied to certain HS code ranges. Read our guide on understanding SABER to understand how HS codes relate to Saudi certification requirements.
Mistake 4: Misclassifying Multi-Component Products
Products that contain multiple components (e.g., a machine with accessories) are often misclassified. The essential character rule dictates that a set should be classified based on the component that gives it its essential character. Consult a customs broker or compliance specialist when classifying complex multi-component products.
Mistake 5: Failing to Account for Special Trade Agreements
Many countries have preferential tariff rates for products imported under free trade agreements (FTAs). Exporters sometimes miss these opportunities by using the wrong HS code that does not qualify for the preferential rate, resulting in higher import duties being applied.
HS Codes and Egyptian Regulations
For exporters targeting Egypt, HS code accuracy is particularly important due to the new Egyptian import regulations for 2026, which require CoC certificates tied to specific HS code classifications.
HS Codes for Food Exports
Food exporters to Saudi Arabia must ensure their HS codes align with SFDA requirements. Our SFDA food export compliance checklist provides guidance on matching your HS codes to the correct regulatory category.
Building Materials and HS Codes
Construction products are particularly prone to HS code misclassification. Our guide on building materials certification for Saudi Arabia includes important notes on HS code requirements for construction products.
