Mandatory Customs Document Checklist (100% Required for Clearance)

Missing or incorrect documents are the #1 cause of customs holds. Use this **official, complete document checklist** to guarantee acceptance by both China and Singapore customs:

Document Quality Rules (Non-Negotiable)

• All documents must be in ENGLISH
• No handwritten changes or corrections
• Consistent data across all papers
• Signed and dated by authorized personnel
• Digital copies must be high-resolution and valid

HS Code Classification: The Key to No Customs Holds

HS Codes (Harmonized System Codes) are 6–10 digit international product classification codes. They determine duty rates, GST, regulations, and customs eligibility.

HS code errors are the #2 cause of customs delays, fines, and seizures. Correct classification is non-negotiable.

Why HS Codes Matter

• Define tax and duty calculations
• Determine if goods are regulated or restricted
• Trigger or avoid customs inspections
• Affect customs clearance speed
• Prevent legal penalties and fines

Expert HS Code Classification Strategies (Broker Secrets)

1. Classify Based on Product Function & Material

Customs classify goods by what they ARE, not what you call them. Focus on material, purpose, and features.

2. Verify BOTH China & Singapore HS Codes

HS codes are mostly aligned but may have slight differences. Confirm both countries’ codes.

3. Never Guess or Use Supplier Codes Blindly

Suppliers often provide wrong HS codes to simplify export. Always verify professionally.

4. Use Licensed Classification Services

Professional brokers have direct access to customs databases and official rulings.

5. Document Classification Reasoning

Keep records to defend your classification if questioned by customs.
