Why This Guide Exists
The problem: China is Japan's largest import source country by volume. Yet the compliance landscape for China-to-Japan shipments is among the most layered in the region. Bilateral trade operates across RCEP preferential tariffs, Japan-specific product certification requirements (PSE, Radio Act, medical, food), FEFTA dual-use controls, and a reformed customs clearance system that changed the definition of "importer" in October 2023.
The cost of getting it wrong: Mis-declared HS codes result in five-year retroactive duty assessments. Non-compliant electronics are seized at port. FEFTA violations involving controlled technology carry criminal penalties. Japan Customs processes approximately 36 million import declarations per year through NACCS and runs systematic post-clearance audits.
The China-Japan Trade Framework
RCEP: The First-Ever Preferential Trade Relationship Between Japan and China
Japan and China do not have a bilateral free trade agreement. However, both became founding parties to the Regional Comprehensive Economic Partnership (RCEP), which entered into force for Japan and China on January 1, 2022. This was the first time a preferential tariff relationship existed between the two countries.
Under RCEP at launch, zero tariffs applied immediately to approximately 57% of Chinese goods exported to Japan. The remaining eligible categories follow a staged elimination schedule extending to 2037.
| Trade Framework | Status | Rate |
|---|---|---|
| Bilateral FTA | None | - |
| RCEP | In force since January 1, 2022 | Preferential (staged schedule) |
| MFN (default) | Always applies unless preference claimed | Japan WTO schedule |
⚠️ RCEP preference must be claimed at the time of import declaration. If no origin documentation is submitted, Japan Customs applies the MFN rate by default. RCEP preference cannot be backdated after clearance is complete.
RCEP Rules of Origin - What Determines Eligibility
To claim RCEP preferential rates, goods must satisfy origin requirements under the agreement.
| Requirement | Detail |
|---|---|
| Origin criterion | Wholly Obtained in China (WO) or meets the Product-Specific Rule (PSR): most commonly a Change in Tariff Classification (CTC) or Regional Value Content (RVC) threshold |
| Origin documentation | RCEP Certificate of Origin (Form RCEP-1) or origin declaration by approved exporter |
| Tariff staging | RCEP rates phase in over time: some categories reach 0% immediately, others over 5–20 years |
| Bilateral accumulation | Chinese inputs in goods processed in China count toward origin |
⚠️ Product-Specific Rules vary significantly by HS chapter. Confirm the specific PSR for your heading before claiming RCEP preference at declaration.
Japan Customs Procedures - Step by Step
The NACCS System
All import declarations in Japan are filed electronically through NACCS (Nippon Automated Cargo and Port Consolidated System). Paper declarations are not accepted for standard commercial imports. NACCS validates HS headings, duty rates, and required documentation in real time at the moment of filing.
| Step | Action | Typical Timeline |
|---|---|---|
| 1 | Obtain customs clearance registration (non-resident: ACP appointment) | 3–4 weeks one-time |
| 2 | Prepare import documentation | Before cargo arrival |
| 3 | File import declaration via NACCS | At or before cargo arrival |
| 4 | Customs examination (physical or document review) | 1–3 business days |
| 5 | Pay customs duty and JCT | Upon assessment |
| 6 | Customs release issued (輸入許可) | After payment confirmed |
Key Import Documents
| Document | Required | RCEP Notes |
|---|---|---|
| Commercial invoice | Mandatory | - |
| Packing list | Mandatory | - |
| Bill of Lading or AWB | Mandatory | - |
| RCEP Certificate of Origin (Form RCEP-1) | Required if claiming RCEP rates | Submit at declaration |
| Customs power of attorney | Required if using ACP or licensed broker | - |
Duty Rates: MFN vs RCEP
How to Calculate Your Japan Import Cost
CIF Value = Cost of goods + Insurance + Freight to Japan port of entry
Customs Duty = CIF Value × Tariff Rate (MFN or RCEP preferential)
JCT = (CIF Value + Customs Duty) × 10%
Total Import Cost = CIF Value + Customs Duty + JCT
Example: Why RCEP Preference Matters
| Example A (MFN, 5% rate) | Example B (RCEP, 0% rate) | |
|---|---|---|
| Goods cost | $50,000 | $50,000 |
| Freight + Insurance | $2,000 | $2,000 |
| CIF Value | $52,000 | $52,000 |
| Customs Duty | $2,600 (5%) | $0 (0%) |
| JCT (10%) | $5,460 | $5,200 |
| Total Import Cost | $60,060 | $57,200 |
| RCEP savings | - | $2,860 per shipment |
Common Product Categories: MFN vs RCEP Rates
| Category | HS Chapter | MFN Rate | RCEP Rate (2026 approx.) |
|---|---|---|---|
| Electronic components | 8534, 8541, 8542 | 0% | 0% |
| Consumer electronics | 8517, 8528 | 0% | 0% |
| Lithium-ion batteries | 8507.60 | Free | Free |
| Electric motors | 8501 | Free | Free |
| Industrial machinery | Chapter 84 | 0–3.9% | Staged reduction |
| Clothing and textiles | Chapter 61–63 | 5.6–16% | Staged reduction |
| Processed food | Chapter 21 | 6.4–25% | Category-specific |
| Agricultural products | Chapter 01–24 | Variable | Limited concessions |

Product Compliance Requirements: Where China-to-Japan Imports Create Friction
Customs duty is only one layer. Japan maintains category-specific certification requirements that are independent of HS classification and duty rates. These are the requirements that most frequently cause shipment delays or seizure.
Electrical Products: PSE (電気用品安全法 / DENAN)
Almost all electrical products imported for distribution in Japan require PSE certification. Shipments without valid PSE are subject to seizure and are prohibited from sale. This applies to products certified in China, the EU, or the US - Japanese certification is independent.
| PSE Mark | Products | Testing |
|---|---|---|
| Diamond PSE (◇) | 116 Specified Electrical Appliances (高リスク品) | Third-party certification lab required |
| Circle PSE (○) | All other regulated electrical appliances | Self-certification against Japanese standards |
Common China-origin products by mark:
- Diamond (◇): air conditioners, electric water heaters, space heaters, some industrial equipment
- Circle (○): consumer electronics, electric fans, hair dryers, microwave ovens, chargers
Wireless Devices: Radio Act (電波法) / TELEC Certification (技適)
Any device that emits radio waves - Wi-Fi, Bluetooth, ZigBee, LTE, 5G, GPS, satellite - requires TELEC (技適) certification under Japan's Radio Act before it can be imported for commercial distribution. CE, FCC, or SRRC certification does not substitute for Japan certification.
| Device Type | Requirement | Body |
|---|---|---|
| Wireless consumer devices | TELEC mark (技適) | TELEC, MKK, or designated testing body |
| Satellite ground equipment | MIC license | Ministry of Internal Affairs and Communications |
⚠️ Importing uncertified radio devices for "testing purposes" requires a separate experimental station license (実験局免許) from MIC - this is not a commercial import authorization.
Food and Agricultural Products
| Requirement | Authority | Applicability |
|---|---|---|
| Food Sanitation Act compliance | MHLW | All food imports - inspection at port |
| Plant quarantine | MAFF | Plants and plant-based products |
| Animal quarantine | MAFF | Animal products, livestock |
| Pesticide residue (0.01 ppm default) | MHLW | Agricultural products - strict limits |
Medical Devices: PMD Act (薬機法)
Medical devices require PMDA pre-market registration or notification before import and distribution. China-origin CE-marked devices are not automatically recognized in Japan. Classification determines the registration path (Class I–IV).
FEFTA Dual-Use Controls: The Hidden Compliance Layer
The Foreign Exchange and Foreign Trade Act (外為法 / FEFTA) applies a technology-import screening layer that is entirely independent of customs classification and product certification requirements.
When FEFTA Pre-Import Clearance Is Required (外為法第52条)
FEFTA screening is triggered by:
- List Control: The product's HS heading appears on METI's controlled goods list (輸出貿易管理令 annexes)
- Catch-All Clause: The product has dual-use technical characteristics - even with a civilian HS heading - and the importer knows or has reasonable grounds to believe it could be used for weapons programs or certain military applications
Common China-origin products that trigger FEFTA review:
| Category | Trigger Type | Notes |
|---|---|---|
| Telecommunications infrastructure | List Control | Certain HS 8517 specifications |
| Lasers and optical systems | List / Catch-All | Power output, wavelength, precision thresholds |
| High-precision inertial sensors (IMU, GPS) | Catch-All | End-use and end-user analysis required |
| CNC machine tools with high tolerances | List Control | Specific tolerance specifications |
| Chemical precursors | List Control | Also subject to 化審法 separately |
| Drones with advanced stabilization and imaging | Catch-All | Military application potential assessment |
⚠️ FEFTA pre-import clearance (外為法第52条) must be obtained before the import declaration is filed in NACCS. The HS heading cited in your FEFTA application and your NACCS declaration must match exactly. A discrepancy creates direct exposure under Article 52.
Import Structure Options for Chinese Exporters and Japan Buyers
If you are shipping from China without a Japan entity, two compliant structures are available post-October 2023.
IOR (Aplash as Japan Importer)
Aplash purchases the goods from you at an agreed price, clears customs as the Japan-resident importer, and re-sells to the Japan buyer. You receive payment as the overseas seller with no Japan tax or customs obligations.
ACP (You as Non-Resident IOR, Aplash as Customs Agent)
Your company is the legal importer named on the customs declaration. Aplash, as your appointed ACP (税関事務管理人) under 関税法第95条, handles all NACCS filings. You recover Japan import JCT via 納税管理人 + QIS registration. Prerequisite: your entity must have no Japan address, residence, or office.
| Factor | IOR (Aplash as Importer) | ACP (Your Company as Importer) |
|---|---|---|
| Who is IOR on declaration | Aplash | Your company |
| JCT recovery for you | Not available | Yes, via QIS + 納税管理人 |
| Setup complexity | Low | Medium (two registrations) |
| Best for | One-time or lower volume | Recurring, JCT-sensitive |
Common Mistakes in China-to-Japan Imports
| Mistake | Consequence | Prevention |
|---|---|---|
| Claiming RCEP without a valid Certificate of Origin | MFN rate applied; potential underdeclaration penalty | Obtain Form RCEP-1 from Chinese export authority before shipment |
| Using an abolished HS heading (e.g., 8525.xx series) | NACCS declaration rejected at filing | Verify against current Japan tariff schedule, not WCO alone |
| Shipping wireless devices without 技適 certification | Seized at port; import prohibited | Obtain TELEC certification before first shipment |
| Assuming CE or FCC = Japan compliance | Japan certification is entirely independent | Separate Japan certification process required |
| Inconsistent HS heading between FEFTA filing and NACCS | 外為法 Article 52 exposure | Lock heading in advance; update both filings simultaneously |
| Nominee IOR arrangement post-October 2023 | Japan Customs challenge to importer eligibility | Use ACP or genuine IOR (Aplash) |
| Declaring transaction value between related parties without documentation | Customs valuation challenge | Prepare arm's-length documentation before declaration |
Pre-Shipment Compliance Checklist: China to Japan
