- Classify watch components for more accurate HTS codes
- Estimate US import duties using live official tariff rates
- Apply origin-based tariff surcharges to duty estimates
- Fill Shopify customs fields and generate a customs worksheet
Classify watches into HTS codes, estimate US import duties, and auto-fill store customs fields.
Importing watches into the US is uniquely complicated: customs doesn't charge one duty on the product — it charges separate rates on the movement, case, band, and battery, each with its own tariff line. Get it wrong and you overpay or face delays at the border. ChronoBase Customs does the hard part automatically — it researches your product, pulls current rates from the official US tariff schedule, and pushes ready-to-use customs data to Shopify, with a printable worksheet for every entry.
