Export Customs Clearance FAQ & Compliance Guide
1. Basic Export Clearance Process
Export clearance generally includes the following steps: ① the customer provides the packing list, invoice, contract and declaration elements → ② the customs broker confirms the HS code classification → ③ electronic filing via the China International Trade Single Window → ④ automatic review by the customs system (or referral to manual review) → ⑤ customs release/inspection → ⑥ loading and shipment of the goods.
Currently about 75% of export declarations at Shanghai ports are released through automatic system review ("instant release"), with the rest going to manual review or targeted inspection. Well-prepared and complete documents are the key to fast clearance.
2. Common Rejection Reasons and How to Avoid Them
HS Code Classification Errors
This is the most frequent rejection reason. Different HS codes correspond to different export supervision conditions and tax rebate rates. For example, LED luminaires under 9405 get a 13% rebate but require inspection, while those under 9405409000 get a 17% rebate with no inspection. Classification errors may lead to rejection and re-filing at best, or be deemed false declaration and face penalties at worst.
Advice: when unsure about the HS code, provide a detailed product description (material, purpose, function) and let a professional customs broker assist with classification.
Incomplete or Inaccurate Declaration Elements
Every HS code has corresponding declaration element requirements (brand, model, material, purpose, etc.); missing any one will be rejected by the system. For example, textiles must declare "weaving method", "composition content" and "grammage per square meter" — none can be omitted.
Inconsistent Document Data
Invoice amounts not matching declared values, packing list piece/weight/measurement inconsistent with declared data, contract numbers not matching invoices — these "basic errors" are common yet entirely avoidable. We recommend using a unified export documentation template to ensure data consistency.
3. Key Compliance Practices
- Declare the value truthfully; never under- or over-declare (forex verification and tax rebate audits cross-check figures)
- Export tax rebate enterprises must ensure consistency across the invoice, goods and payment flows
- Branded goods require a brand authorization letter or a declaration of self-owned brand
- Wooden packaging must carry the IPPC fumigation mark, otherwise it may be returned at the destination port
- For licensed goods (dangerous chemicals, food, medical devices, etc.), obtain the required permits in advance
