Where Import Estimates Go Wrong: HS Classification
By George · updated 2026-08-24 · checked against the 2026 Bahamas tariff schedule
When a Bahamian import bill comes in far above expectation, the cause is almost never arithmetic. It is classification — the product was matched to the wrong tariff line, and every number downstream inherited the error.
How the schedule is built
The Bahamas tariff schedule follows the international Harmonized System. It has 97 chapters, about 1,276 four-digit headings, and 6,699 individual tariff lines. Classification narrows 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%; 8518.2200 is loudspeakers at 45%
Those last two live in the same heading, four digits apart, with a 45-point duty gap between them. That is the whole problem in one example.
The four places it goes wrong
1. Sibling lines with wildly different rates. Headphones and speakers. Baby clothing (0%) and adult clothing (20%). Cribs (0%) and furniture (25%). The schedule is full of deliberate carve-outs, and a classifier that works from a product title rather than the actual heading text will miss them.
2. Marketing categories are not tariff categories. "Electronics" is not a heading. A laptop, a phone and a soundbar are 0%, 10% and 45%. Any estimate built on the shopping-site category rather than the tariff code is guessing.
3. The general rate is a fallback, not an answer. Goods that cannot be classified fall to the general rate of 35%. That is a placeholder for "we do not know," and it is wrong in both directions — badly over-stated for the many duty-free lines, understated for the 45% and 60% ones.
4. Duty-free does not mean tax-free. A line can be 0% under the Tariff Act and still carry excise under the Excise Act — the situation for vehicles, fuel and spirits. See the excise trap.
Why Amazon's deposit disagrees with the Bahamas figure
Amazon's Import Fees Deposit is generated from Amazon's own product-to-tariff mapping, applied across every destination country. It is not reading the Bahamian schedule, and it does not know that The Bahamas zero-rates computing equipment or charges 60% on mattresses. Sometimes it over-collects and you get a refund; sometimes it under-collects and the balance appears at the border.
That gap is the entire reason this site exists — every product page puts the deposit next to the Bahamian calculation and shows the difference.
How to check a classification yourself
- Find the chapter by what the product is made of or does, not by what shop sold it. Browse the schedule by chapter.
- Read the heading text, not just its friendly name. Headings carry exclusions — "other than," "excluding" — that move a product somewhere else entirely.
- Compare the sibling lines under that heading. If two lines could plausibly fit and they carry different rates, that is exactly where an automated estimate will have guessed.
- Check for excise and levy on the line, not just duty.
- Look it up: paste a product link into the lookup tool and compare its answer to your own reading.
How duty242 handles uncertainty
Classifications on this site carry a confidence level, and lines individually checked against the current schedule are marked verified. Where the schedule publishes a charge that cannot be computed from a price — excise charged per gallon, for instance — the figure is flagged as an unquantified extra rather than shown as zero. An estimate that is confidently wrong is worse than one that admits what it does not know.
Final classification and charges are always determined by Bahamas Customs.
