Where Import Estimates Go Wrong: HS Classification
By George · updated 2026-09-30 · worked examples checked against the Bahamas Tariff Act (schedule version 2026-2027)
When an import bill comes in far above what you expected, the arithmetic is rarely the problem. The usual cause is classification: the product was matched to the wrong tariff line, and every figure after that was based on it.
How the schedule is organised
The Bahamas tariff schedule follows the international Harmonized System. It has 97 chapters, about 1,277 four-digit headings and 6,702 individual tariff lines, and classification works from the general to the specific:
- Chapter (2 digits): chapter 85 is electrical machinery and equipment
- Heading (4 digits): 8518 is microphones, headphones, amplifiers and loudspeakers
- Tariff line (8 digits): 8518.3000 is headphones at 0%, and 8518.2200 is loudspeakers at 45%
Those two lines are in the same heading and 45 points of duty apart. Most classification problems look like that.
Four common mistakes
1. Neighbouring lines with very different rates. Headphones and speakers. Baby clothing (0%) and adult clothing (20%). Cribs (0%) and other furniture (25%). The schedule has many deliberate exceptions like these, and a classifier that works from a product title instead of the heading text will miss them.
2. Shop categories aren't tariff categories. "Electronics" isn't a heading. A laptop, a phone and a soundbar are 0%, 10% and 45%, and an estimate based on the store's category rather than the tariff code is a guess.
3. The general rate is a fallback. Goods that can't be classified fall to the general rate of 35%. That only means "unknown", and it's wrong both ways: far too high for the many duty-free lines, and too low for the 45% and 60% ones.
4. Duty-free doesn't mean tax-free. A line can be 0% under the Tariff Act and still carry excise under the Excise Act, as vehicles, fuel and spirits do. See duty-free but not tax-free.
Why Amazon's deposit differs from the Bahamas figure
Amazon's Import Fees Deposit comes from Amazon's own product-to-tariff mapping, which it uses for every destination country. It doesn't read the Bahamas schedule, so it doesn't know that computers are duty-free here or that mattresses are 60%. Sometimes it collects too much and you get a refund; sometimes it collects too little and you pay the balance at the border.
That gap is why this site exists. Every product page shows the deposit next to the Bahamas calculation.
How to check a classification yourself
- Find the chapter by what the product is made of or what it does, not by which shop sold it. You can browse the schedule by chapter.
- Read the heading text, not just its short name. Headings carry exclusions ("other than", "excluding") that move a product somewhere else entirely.
- Compare the neighbouring lines under that heading. If two of them could fit and they have different rates, that's exactly where an automated estimate will have guessed.
- Check the line for excise and levy as well as duty.
- Look it up: paste a product link into the lookup tool and compare its answer with your own reading.
How duty242 handles uncertainty
Each classification on this site has a confidence level, and lines that have been checked individually against the current schedule are tagged verified. Where a charge can't be worked out from a price, such as excise charged per gallon, it's flagged as an extra rather than shown as zero.
Final classification and charges are always determined by Bahamas Customs.
