Key Takeaways
- An HS Code is not just a product code; it affects compliance for the entire shipment.
- Product details, materials, components, and usage affect the classification.
- New products should have their classification verified with experts or relevant authorities.
Why HS Codes Affect Pricing
Customs classification is linked to import duties, taxes, and product control measures. Sometimes products that look similar may fall under different classifications due to differences in materials, usage, or components. Therefore, one should not guess the code based on short product names in a quote.
If the HS Code changes after a quote, the total cost may change accordingly because taxes, permits, or clearance procedures differ from the initial assessment.
- Duties and taxes
- Permits or control measures
- Statistical data
- Risk of retrospective audits
Information that Helps Ensure Accurate Classification
You should prepare product photos, catalogs, specifications, materials, components, instructions for use, and previous invoice examples if available. For machinery, electrical equipment, or chemical products, a technical datasheet should be provided so the customs broker or experts can inspect it in detail.
