AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
To classify a product from Nigeria, read the US Harmonized Tariff Schedule from the heading down using the General Rules of Interpretation: first the terms of the headings and the section and chapter notes, then the narrower subheadings. The 8-digit line sets the duty rate and the 10-digit number is for statistics, according to CBP's classification guide. The importer must use reasonable care, and can check CBP's rulings database or ask for a binding ruling.
Why the code matters
The HTS code on your entry decides the ordinary duty rate, whether extra tariffs or exclusions apply, and which other agencies, such as the FDA or USDA, take an interest. CBP's informed compliance publication on tariff classification says the importer of record must use "reasonable care" to classify goods, and that failing to do so can lead to delays, higher duties with interest, detention, seizure or penalties. CBP sets the final classification when the entry is liquidated, so a wrong code can cost money long after the goods are sold.
Classification is also the first thing a broker asks for. If you hand over a vague description such as "African foodstuff" or "fabric", you are asking the broker to guess, and the guess is made in your name as importer. A precise description of what the product is made of, how it is processed and what it is used for is what turns a guess into a defensible code.
How the schedule is built
The US schedule (HTSUS) is based on the international Harmonized System. CBP's guide describes the levels:
| Level | Digits | What it is |
|---|---|---|
| Chapter | 2 | The HTSUS has 22 sections and 99 chapters; chapters 98 and 99 are for US national use. |
| Heading | 4 | Broad product description; the first two digits show the chapter. |
| Subheading | 6 | The international level, shared with other countries. |
| US rate line | 8 | The legal US level where duty rates apply. |
| Statistical suffix | 10 | For trade statistics only; not legal authority for classification. |
Duty rates appear in columns. Column 1 General is the rate for countries with normal trade relations; Column 1 Special shows preference programmes; Column 2 applies to a small number of countries without normal trade relations.
The rules of interpretation, in plain words
- GRI 1: classify by the wording of the headings and the section and chapter notes. Most goods are settled here. Read the notes; they often exclude things you would expect to be included.
- GRI 2: covers incomplete or unfinished goods, unassembled or disassembled goods, and mixtures or combinations of materials.
- GRI 3: if two headings fit, use the most specific; if that fails, the material or part that gives essential character; if that fails, the heading last in numerical order.
- GRI 4: goods that fit nowhere go with the goods they are most like. Rarely used.
- GRI 5: cases and packing go with their contents in most cases.
- GRI 6: apply the same steps at subheading level, comparing only subheadings at the same level.
The World Customs Organization's Explanatory Notes are not legally binding but are, CBP says, generally treated as persuasive. They are often the clearest guide to what a heading covers.
Worked approach for typical Nigerian goods
The examples below show the method, not the answer. We do not give codes because the right one depends on details only you have.
- Garri: ask what it is in tariff terms. It is a processed product of a root (cassava), granulated and toasted. Search the schedule for cassava and for flours and meals of roots, read the chapter notes on what processing moves a product to another chapter, and check whether any ingredient was added.
- An ankara dress: the material (cotton woven fabric, printed), the construction (woven, not knitted), and the wearer (women's or girls') each narrow the heading. A label with fibre content is needed anyway; see textile labelling.
- Shea butter: is it a raw vegetable fat or a cosmetic preparation? Packaging and marketing for skin use can change the answer, and the FDA treatment too.
- A gift set of black soap, a sponge and shea butter: GRI 3 on sets and essential character applies.
Where to check your answer
- Search CBP's Customs Rulings Online Search System (CROSS) at rulings.cbp.gov for rulings on similar goods. A ruling for someone else's goods is not binding on yours, but it shows CBP's reasoning.
- For certainty before you import, request a binding ruling under 19 CFR Part 177; see how to request a binding ruling.
- Use a licensed customs broker for complex goods. CBP's guide notes that relying only on its general publication may not count as reasonable care.
Keep a classification file
For each product you import regularly, keep a one-page note: a photo, the materials and percentages, how it is made and used, the HTS code you chose, the headings you ruled out and why, and any CROSS rulings you relied on. If CBP asks questions at liquidation, that file is your evidence of reasonable care. Update it when the supplier changes the recipe, the fabric or the packaging, because a change in materials can change the code.
After classification, check the additional duties for products of Nigeria; see current US tariffs on Nigerian goods.
Where Pryme fits
Knowing the code lets you price landed cost before you pay a supplier. A Pryme Business Account holds dollars and naira (business multicurrency), and the Finance agent can prepare a landed-cost note for your review.
Questions people ask
How do I find the HTS code for a product from Nigeria?
Read the schedule from the heading down using the General Rules of Interpretation, starting with the headings and chapter notes, then check CBP's CROSS rulings database for similar goods.
Is the 10-digit HTS number the legal code?
No. CBP says the 8-digit line is where duty rates apply, and the 10-digit suffix is for statistics only.
Who is responsible if the HTS code is wrong?
The importer of record, who must use reasonable care. CBP can reclassify at liquidation and charge extra duty with interest.
Can CBP tell me the right HTS code in advance?
Yes. You can request a binding ruling under 19 CFR Part 177, which CBP says it provides without charge.
