HS Code Finder: Get Your Customs Codes Right

A seller I know once shipped 200 units of silicone phone cases to Germany, declaring them as "phone accessories" with HS code 8517.70, which refers to parts for telephones. This was incorrect. The correct code was 3926.90, which is for other articles of plastics. This mistake resulted in an 8% tariff instead of 0%. Consequently, German customs flagged the shipment, held it for 11 days, and imposed an additional fee on the buyer for reclassification. This led to a one-star review and a filed dispute from the buyer.

HS codes are critical for international shipping. They determine the taxes and duties a country applies to your products at the border. Misclassifying them can lead to delays, extra charges, and dissatisfied customers.

What HS Codes Are

The Harmonized System (HS) is a standardized numerical method for classifying traded products. Developed by the World Customs Organization, it is adopted by over 200 countries worldwide.

Each product crossing an international border must be classified under an HS code. The first six digits are universal and consistent globally, while additional digits are country-specific to accommodate individual tariff schedules.

HS Code Structure

HS codes are structured to provide detailed product categorization. The layout is as follows:

• First 2 digits (Chapter): These represent broad categories. For example, "39" indicates plastics and articles thereof.
• First 4 digits (Heading): This provides more specificity, such as "3926" for other articles of plastics.
• First 6 digits (Subheading): This narrows it further, like "3926.90" for other articles of plastics not specified elsewhere.
• 8-10 digits (Country-specific): These digits, such as "3926.90.9996" in the US, provide the exact tariff line for specific countries.

The international standardization of the first six digits allows for a unified system, while the additional digits offer the flexibility needed for country-specific tariffs.

How Many HS Codes Exist?

The vast array of HS codes can be overwhelming:

• Chapters (2-digit): There are 97 chapters.
• Headings (4-digit): Approximately 1,200 headings exist.
• Subheadings (6-digit): Around 5,600 subheadings are available.
• US HTS lines (10-digit): Nearly 19,000 tariff lines are used.

This complexity is why HS codes are frequently misclassified, leading to significant implications.

Why Wrong HS Codes Cost You Money

Incorrect HS codes can trigger a cascade of costly issues:

Higher duties than necessary. Some HS codes carry 0% duty rates, while similar-sounding codes may incur duties ranging from 15-25%. Misclassification can result in overpayment by your customers or yourself, particularly if you ship DDP (Delivered Duty Paid).

Customs holds and delays. If the declared HS code doesn't match the product, customs may flag the shipment for inspection, leading to delays averaging 5-15 business days.

Fines and penalties. Consistent misclassification can result in penalties. In the US, intentional errors can lead to fines up to $10,000 per occurrence.

Seized shipments. Some codes may trigger import restrictions or require special licenses, leading to the potential seizure of goods if reclassified into a restricted category.

Real Examples of Costly HS Code Mistakes

Consider some real-world examples where incorrect HS codes led to significant issues:

• Silicone phone case: Incorrectly classified as phone parts (8517.70) instead of plastic articles (3926.90), resulting in an 8% duty and an 11-day delay.
• Bamboo cutting board: Incorrectly flagged for review due to wrong classification as wood kitchenware (4419.19) instead of other wood articles (4419.90).
• LED desk lamp: Misclassified as LED lamps (9405.42) instead of portable electric lamps (8513.10), requiring different safety certifications.
• Cotton t-shirt: Misclassified as cotton t-shirts (6109.10) instead of cotton pullovers (6110.20), leading to a 4% vs 16.5% duty discrepancy in certain markets.
• Stainless steel water bottle: Incorrectly classified as stainless steel table/kitchen articles (7323.93) instead of vacuum flasks (9617.00), affecting tariff treatment.

These examples underscore the importance of precise HS code classification to avoid unnecessary costs and delays.

How to Find the Right HS Code

Step 1: Identify What Your Product IS (Material + Function)

HS codes primarily classify products based on material composition and function. Consider:

• What is the primary material? (e.g., plastic, metal, textile)
• What is the primary function? (e.g., clothing, tool, decoration)
• Is it a finished product or a component?
• Is it intended for consumer or industrial use?

Step 2: Start with the Chapter

Understanding the general category of your product helps narrow down the options:

• 01-24: Food, animals, agricultural products
• 25-27: Minerals, fuels
• 28-38: Chemicals
• 39-40: Plastics and rubber
• 41-43: Leather and furs
• 44-46: Wood products
• 47-49: Paper products
• 50-63: Textiles and clothing
• 64-67: Footwear, headwear
• 68-70: Stone, ceramic, glass
• 71: Jewelry and precious metals
• 72-83: Base metals
• 84-85: Machinery and electronics
• 86-89: Vehicles and transport
• 90-92: Instruments and apparatus
• 93: Arms and ammunition
• 94-96: Furniture, toys, miscellaneous
• 97: Art and antiques

Step 3: Use Official Lookup Tools

Utilize reliable tools to find the appropriate HS code:

• USITC HTS Search: For US-specific 10-digit codes.
• WCO HS Online: For international 6-digit codes.
• EU TARIC: For EU-specific codes and duties.
• Canada CBSA: For Canadian tariff codes.
• Atoship HS Finder: Integrated into label creation for multi-country lookup.

Step 4: Check the Section and Chapter Notes

Each HS chapter begins with legal notes defining its scope. Many errors occur because people skip this step. For example, Chapter 39 (Plastics) Note 2 excludes goods of Section XI (textiles), meaning a plastic-coated fabric might fall under textiles rather than plastics. These nuances are only clear if you read the notes.

Step 5: Verify Against Customs Rulings

The US Customs and Border Protection maintains a database of classification rulings. Search for similar products to see their official classifications. This database is invaluable; if the CBP has made a ruling on a product like yours, it provides authoritative guidance.

HS Codes and Free Trade Agreements

Your HS code influences whether a product qualifies for reduced duties under free trade agreements like the USMCA or other preferential trade deals. These agreements offer reduced or zero duties for qualifying goods, but correct HS classification and proof of origin are essential.

Tips for Getting HS Codes Right

Never guess. Always verify the HS code.

Classify the finished product, not components. A watch is classified as a watch, not as separate leather or metal items.

Use the more specific description when available. Specificity trumps generality.

Consider material when function is ambiguous. Material differences often dictate separate codes.

Consult a customs broker for high-volume shipments. Their expertise can prevent costly misclassifications.

Document your classifications. Maintain records of your reasoning to support your decisions if questioned by customs.

Building Your Product HS Code Database

Ecommerce sellers shipping internationally should maintain a reference spreadsheet:

• Product SKU: Internal reference.
• Product Description: Detailed for customs.
• HS Code (6-digit): Universal identification.
• US HTS (10-digit): Specific for US exports.
• Country of Origin: Manufacturing location.
• Declared Value: Per-unit value for customs.
• Notes: Documented classification reasoning.

Ensure accuracy from the start to prevent future problems. Accurate HS codes are crucial for smooth international operations and customer satisfaction.
