Why “Taxes Are Higher Than Expected” in Food Imports
People who are new to food importing often say things like:
- “The taxes seem higher than what I found online.”
- “I followed an explanation for personal imports, but it didn’t match.”
- “I thought customs duty would be low, but the consumption tax is heavy.”
In most cases, the reason is simple:
👉 They are confusing the tax rules for personal imports and commercial imports.
This is especially critical for food imports, because:
- Almost all food imports are treated as commercial imports
- The personal import “60% valuation rule” does not apply
As a result, the tax calculation method is fundamentally different.
In this article, using food imports as the main example, we will explain for beginners to intermediate readers:
- The difference in tax rules between personal and commercial imports
- How customs duty and consumption tax are calculated for commercial (food) imports
- Common mistakes made in real import operations
The Key Conclusion First: Food Imports Are Almost Always “Commercial Imports”
Here is the most important takeaway upfront.
👉 Food imported for resale is, in principle, always treated as a commercial import.
- Corporations and sole proprietors → Commercial import
- Side businesses and small-lot imports → Commercial import
- Selling on Amazon or through retail channels → Commercial import
The idea that “small quantities qualify as personal imports” does not apply to food.
Differences in Tax Rules Between Personal and Commercial Imports
Comparison of Tax Calculation Rules
| Item | Personal Import | Commercial Import (Food) |
|---|---|---|
| Import purpose | Personal use | Resale / business use |
| Taxable value | Product price + freight × 60% | Product price + freight (100%) |
| Special rules | 60% rule applies | No special reduction |
| Duty rate | Often simplified rates | Official tariff rates |
| Consumption tax | 10% | 10% |
| HS code | Simplified | Formal HS classification required |
👉 The biggest difference: the 60% rule cannot be used for food imports.
Basic Tax Structure for Commercial (Food) Imports
There are two types of taxes paid when importing food:
① Customs Duty
- Duty rates vary by food category
- Processed foods and confectionery generally have duty rates
- Rates may also change depending on ingredients
② Consumption Tax
- Flat rate of 10%
- Applies even if customs duty is 0%
👉 Customs duty + consumption tax = total import taxes

Understanding “Taxable Value” in Commercial Imports
Taxable Value for Commercial Imports (Very Important)
For commercial imports, the taxable value is simply the total of:
- Product price (FOB or CIF value, depending on Incoterms)
- International freight
- Insurance (if applicable)
Taxable value = Product price + International freight + Insurance
👉 There is no 60% reduction.
If you think about this using the same logic as personal imports, it leads to the feeling that “taxes are too high.”
How Taxes Are Calculated for Food Imports
Step ① Calculate the Taxable Value
Example:
- Product price: JPY 100,000
- International freight: JPY 20,000
Taxable value = JPY 120,000
Step ② Calculate Customs Duty
Duty rates depend on the HS code and food category.
- Some food items: 0%
- Confectionery and processed foods: several percent to around 10%
Assuming a duty rate of 5%:
Customs duty = 120,000 × 5% = JPY 6,000
Step ③ Calculate Consumption Tax
For commercial imports, consumption tax is calculated as:
(Taxable value + customs duty) × 10%
Consumption tax = (120,000 + 6,000) × 10% = JPY 12,600
Total Taxes Payable
- Customs duty: JPY 6,000
- Consumption tax: JPY 12,600
- Total: JPY 18,600
👉 A key feature of food imports is that consumption tax accounts for a very large portion of the total tax burden.
Why There Is Such a Big Difference Between Personal and Food Imports
Even for the same product:
- Personal import: 60% valuation
- Commercial import: 100% valuation
This means the taxable value itself is different.
Example: Product + freight = JPY 120,000
- Personal import: 120,000 × 0.6 = JPY 72,000
- Commercial import: JPY 120,000
👉 This difference is the real reason taxes feel “higher than expected.”
In Food Imports, Classification Errors Are Riskier Than Taxes
In commercial (food) imports, tax rates may change due to:
- Incorrect HS code classification
- Misunderstanding of the food category
- Differences in ingredients and composition
👉 Attempting to reduce taxes through self-judged classification can result in post-clearance corrections or additional assessments.

Common Misconceptions About Food Imports
❌ “It’s a small quantity, so it’s a personal import.”
→ If it’s for resale, it’s a commercial import.
❌ “Customs duty is 0%, so taxes will be low.”
→ Consumption tax of 10% always applies.
❌ “I followed an article about personal imports online.”
→ Those rules do not apply to food imports.
Summary: Always Assume “Commercial Import” for Food
- Food imports are, in principle, all commercial imports
- The personal import 60% rule cannot be used
- Taxable value is 100% of product price plus freight
- Consumption tax has a larger impact than customs duty
- Accurate HS classification is the key to avoiding tax trouble
👉 Food import taxes are not “high” — the rules are simply different.
Once you understand this, cost calculations become much easier.
