A product name is not a classification
The Harmonized System classifies goods by what they are made of, what they do and how they are presented — not by the name on the supplier's invoice. “Pump”, “machine” or “spare part” can each sit under very different headings depending on the details.
A wrong classification can change the duty treatment, trigger permit requirements, or delay a declaration while questions are resolved. Guessing at the border is the most expensive time to find out.
What helps classification
A clear description of the product, its function, its composition, the model or specification, and supporting literature such as a datasheet or catalogue. Photographs help where documents are thin.
You do not need to know the HS code before contacting CGS. Send an accurate description and whatever technical information you have, and the classification work can be done as part of customs preparation.
When an advance ruling may be appropriate
For goods that are repeatedly imported, high in value, or genuinely ambiguous, an advance classification ruling from the relevant authority can give certainty before shipment. Whether that is appropriate for your goods is something to discuss before ordering.
Send the product information early. Classification should be settled before the cargo moves, not at the counter.
This article is general guidance, not legal or customs advice for a specific shipment. Duty rates, tariff codes and regulatory requirements change — confirm current requirements for your goods with CGS.
