จีนเป็นแหล่งนำเข้าที่ใหญ่ที่สุดของสหภาพยุโรป สามจากสี่หมวด DPP แรก — แบตเตอรี่ สิ่งทอ อิเล็กทรอนิกส์ — เป็นสาขาที่โรงงานจีนครอง
แบตเตอรี่ — ก.พ. 2027
จีนผลิต 77% ของเซลล์ทั่วโลก CATL, BYD, CALB
สิ่งทอ — 2028
Shein/Temu: แต่ละ SKU อาจต้องมี DPP ของตัวเอง
อิเล็กทรอนิกส์ — 2028-2029
เซินเจิ้น: Xiaomi, Anker, DJI

ขั้นตอน 1-3

สาเหตุปฏิเสธอันดับ 1
ขั้นตอน 5-7
มี RA ในพื้นที่: 2 สัปดาห์
Hash-only signing
Only SHA-256 hashes leave China. Private keys stay in HSM. Compliant with China Cryptography Law.
Throughput
Tier-1: 50K-200K signatures/day. Two QTSP endpoints for failover.
MES integration
MES generates DPP JSON → hash pipeline → signing API → XAdES-LTA → QR/NFC.
One-time. 3-5 business days with local RA.
XAdES-LTA in MES.
100K/day = ¥2.9M-28.5M/year.
Annual customs audit budget.
Start Q3 2026.
USCI confusion
30% of failures. USCI (18 digits, starts with 9) ≠ business license number.
Name transliteration mismatch
25%. Lock one official English name.
Cryptography Law concerns
15% of delays. Hash-only architecture resolves this.
Throughput underestimated
20%. Test at 3× peak.
Certificate renewal ignored
10%. Plan 60-90 days ahead.
Battery makers
Q3 2026 VEO. Q4 API. Q1 2027 sandbox. Q2 production.
Textile exporters
Assess SKU volume. Map data fields.
Electronics
Budget for DPP in 2027 capital plan.
eSign.AI is RA for ANF AC. Chinese-language document processing (3-5 business days), Chinese SDK, batch signing API (100 DPP/call, 1,000+/min), qualified timestamps, PKCS#1 hash-only signing. Private keys never leave the manufacturer environment.
