I. Summary of Key U.S. Customs Clearance Policies for 2025

These policies were not released in a day; they are basically published and implemented gradually from the end of 2024 to the first half of 2025. Many sellers may have heard about them in bits and pieces, so today I will help you clarify everything at once:

1. Cancel the "minimum tax exemption" policy

  1. From May 2, 2025
  2. All products originating from mainland China and Hong Kong
  3. No matter which country the shipment is sent to, it is no exception for transshipment or overseas warehouse transfer.
  4. As long as it is sent through the postal network, the exemption for amounts under $800 is no longer applicable, and all must pay customs duties.
In other words, the previous "low-priced small package" "T86" model is completely invalid.

2. T86 simplified customs clearance mode canceled applicability

T86=Fast customs clearance channel for small packages under $800 exempt from tax, many e-commerce and freight sellers used to rely on this channel to avoid formal customs declaration.
Starting from 2025, the T86 model is not applicable to goods shipped from mainland China and Hong Kong, and must go through formal customs declaration and tax payment procedures.

3. New various tariff policies

0
Note: The above policies are mostly subject to dynamic adjustments and need to be followed up with announcements in real time.

2. HTS Code & MID Code Practical Sharing

Many customs clearance issues arise from non-standard documents and declaration information, HTS and MID are key:

HTS Code (Harmonized Tariff Schedule) Harmonized Tariff Schedule classification code

  • Issued by the U.S. Customs and Border Protection (CBP), directly determining the product tax rate.
  • 10-digit number, example:
8471300100 → Portable automatic data processing equipment (laptop)
0
Common Product HTS Code Reference (Example)
Practical suggestions:
✔ Confirm the accurate 10-digit HTS code for the product to avoid misclassification affecting the tax rate ✔ Export documents, invoices, and customs materials should maintain consistency in HTS ✔ For highly sensitive categories (steel, aluminum, semiconductors, lithium batteries, and powered products), be sure to verify the codes clearly to avoid high taxes or inspections

MID Code (Manufacturer Identification Code) Manufacturer Identification Code

MID=Manufacturer Identification Code, Format:
【Country of Origin Code】+【Manufacturer Name Abbreviation】+【Address Information Abbreviation】
For example:
Product Source: Shenzhen, Guangdong, China, Manufacturer: ABC Electronics Ltd., Address: No. 88, Fuyong Rd
➡️ MID code entry: CNABCELEF88
0
Common Error Examples:
❌ MID filled with CNUNKNOWN → Information unclear, prone to order cancellation ❌ Simplifying and omitting some information → Increased difficulty in traceability, customs clearance delays ❌ Same manufacturer, different batch information not unified → Easily triggers system risk control
