Origin does not change ranking. When origin is China, result cards show stored Chapter 99 mappings only if a row-level record exists. Broad categories never infer an add-on. Dataset: 356 planning rows · Last verified 2026-09-12.

Duty modeling handoff
HTS lookup ranks classification candidates. The Import Duty Calculator models landed cost only when a usable flat percentage is known. DimMath can prefill the base/general duty rate when it is a simple percentage. A China additional-duty override is prefilled only when a stored Chapter 99 mapping exists for that specific row and origin is China. HS6 fallbacks and unmapped rows never invent an add-on.
HTS vs HS, and 6-digit vs 10-digit
HS-6 is the shared international heading. US entry uses the HTS, which adds 8- and 10-digit statistical suffixes. A 6-digit match is a starting point, not a final line. Duty, MPF, and PGA flags attach to the 10-digit classification that actually describes the article as imported.
Why classification changes duty
Two products that look like “a shirt” or “a bottle” can sit in different headings because fiber content, outer surface, insulation, or principal use changed. That is why this tool asks for material and use instead of inventing a confidence score.
Why China-origin treatment may differ
Column 1 general rates are the base tariff only. Additional Section 301, Chapter 99, or special-program treatments can apply depending on the exact classification and executive actions. DimMath always passes the base/general duty rate when it is a simple percentage. For China-origin rows with a stored Chapter 99 mapping, it can also prefill the additional-duty override as planning data. Unmapped or fallback rows do not auto-fill a China add-on.
What this tool can and cannot do
Can do
- Search likely HTS matches for common ecommerce goods
- Show candidate codes and plain-English descriptions
- Identify whether a rate is a clean ad valorem percentage or complex expression
- Pass the base/general duty rate into the Import Duty Calculator when it is a simple percentage, plus stored China Chapter 99 add-ons for mapped rows
Cannot do
- Issue binding customs rulings or replace a licensed customs broker
- Determine unmapped Section 301, Chapter 99, or special-program tariff treatments beyond stored planning data
- Model quotas, anti-dumping/countervailing duties (AD/CVD), or exclusions
- Guarantee final entry acceptance by US Customs and Border Protection
DimMath shows likely HTS matches and modeling-friendly duty structures for planning. Final customs classification depends on the exact product, material, construction, and use.

Frequently Asked Questions
What is the difference between HS and HTS?
HS is the international 6-digit system. HTS is the US schedule that extends it to 8- and 10-digit lines. US duty follows the HTS line.
Why does material and use change the HTS code?
Fiber, outer surface, construction, and principal use split headings. A cotton tee and a polyester tee are not the same subheading.
Can DimMath auto-classify my product?
No. Ranked matches from a planning table are not a ruling and not broker advice.
When does a result prefill the duty calculator?
Only clean ad valorem percentages are passed as cat=Other and rate. Compound and specific expressions stay as text.
Does China origin change the duty shown?
DimMath always passes the base/general duty rate when it is a simple percentage. For China-origin rows with a stored Chapter 99 mapping, it can also prefill the additional-duty override as planning data. Unmapped or fallback rows do not auto-fill a China add-on.
