π‘ Pro Tips for Memorization
1. The "9" Finger Trick
Hold all 10 fingers up. To multiply 9 Γ n: - Put down your n-th finger. - Count the fingers to the left of the dropped finger as the tens digit. - Count the fingers to the right as the ones digit. - Example (9 Γ 3): Put down the 3rd finger. 2 fingers left (20), 7 fingers right (7) β 27.
2. Commutative Property
Multiplication is symmetric. If you know 6 Γ 7 = 42, you automatically know 7 Γ 6 = 42. - You only need to memorize the upper triangle of the chart (including the diagonal).
3. Easy Numbers First
- Γ1: The number stays the same.
- Γ2: Double the number.
- Γ5: Ends in 0 or 5. Half of 100.
- Γ10: Just add a zero to the end.
4. Squares (Diagonal)
Memorize these "anchor" numbers: - $1^2 = 1$ - $2^2 = 4$ - $3^2 = 9$ - $4^2 = 16$ - $5^2 = 25$ - $6^2 = 36$ - $7^2 = 49$ - $8^2 = 64$ - $9^2 = 81$ - $10^2 = 100$
5. The "8" Pattern
The last digits of the 8 times table repeat in a cycle: 8, 6, 4, 2, 0. - $8 \times 1 = 8$ - $8 \times 2 = 16$ - $8 \times 3 = 24$ - $8 \times 4 = 32$ - $8 \times 5 = 40$ - $8 \times 6 = 48$ - ...and so on.
π Extended Reference: Common Hard Numbers
For faster recall, here are often-memorized specific facts: - $7 \times 8 = 56$ - $6 \times 7 = 42$ - $8 \times 8 = 64$ - $9 \times 9 = 81$ - $12 \times 12 = 144$

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) β Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) β More specific grouping within the chapter
- Subheading (6 digits) β Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) β Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate β The standard duty rate applied to WTO members
- General rate β Applied to countries without trade agreements
- Trade remedy duties β Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
