China to Japan General Cargo Duty Calculator

Between ¥10,000 and ¥200,000, a simplified declaration is available. Above ¥200,000, a formal declaration on Form C-5020 is mandatory. For context: Canada's de minimis is CAD $20 (¥1,500); the US enjoys USD $800. Japan's ¥10,000 sits in the middle — generous for small parcels, but any commercial shipment triggers the full process.

Japan's NACCS — One of the World's Most Efficient Customs Systems

The Nippon Automated Cargo and Port Consolidated System — NACCS — has processed every Japanese import declaration electronically since the late 1970s. Sea freight NACCS and Air NACCS run as separate modules, reflecting the different documentation workflows and risk profiles of ocean versus air cargo.

Speed is NACCS's calling card. Air express clears same-day through Narita, Haneda, or Kansai; sea freight at Tokyo, Yokohama, Osaka, and Kobe clears within one to two business days of arrival. Japan's investment in automation means only a minority of shipments face physical inspection. One requirement: NACCS needs a Japan-domiciled importer of record or a licensed customs broker (tsuukangyou) to file. See our Japan-to-US auto parts calculator.

Key HS Chapters for Chinese General Cargo into Japan

Japan classifies imports under 9-digit HS codes. Chapter 85 (electronics) ranges from 0% for ITA-covered semiconductors and computers to 3.5% for consumer accessories. Chapter 84 (machinery, engines, industrial equipment) runs 0–3.5%, with many lines already at zero under RCEP or the WTO ITA.

Chapters 61 and 62 — apparel, knitted and non-knitted — are steeper: Japan's textile tariffs span 5.3% to 12.8%, reflecting a policy choice to protect domestic producers. Chapter 95 (toys, sports equipment) sits at 0–3.9%; Chapter 94 (furniture, bedding) runs 0–3.8%. Japan has EPAs with ASEAN, the EU, the UK, Australia, and Switzerland, but no bilateral EPA with China — Chinese goods pay full MFN rates across the board.

RCEP Tariff Elimination — The Category-by-Category Timeline

Japan and China have never signed a bilateral free trade agreement. For decades, East Asia's two largest economies traded purely on WTO MFN terms. That changed in January 2022 when RCEP — the Regional Comprehensive Economic Partnership — entered into force, bringing both nations into the same free trade area alongside South Korea, Australia, New Zealand, and the ten ASEAN member states. RCEP is not a single-rate agreement. Each member published its own tariff elimination schedule, and Japan's schedule for Chinese goods is one of the most complex: 1,300+ tariff lines spread across 16 elimination categories, from immediate zero to 21-year phase-outs.

Japan's RCEP schedule classifies every tariff line into a category code that determines how fast the rate drops. Here's what each category means for Chinese imports as of June 2026 (year 5 of the agreement):

• Category A (Immediate elimination): Dropped to zero on January 1, 2022, the day RCEP took effect for Japan. Covers approximately 8% of Japan's tariff lines on Chinese goods — mostly industrial inputs where Japan had no domestic producer to protect: certain chemicals, mineral products, and raw metal ingots. These goods now enter at 0% regardless of origin. If your product is in this category, you've been paying zero duty since 2022.
• Category B5 (5-year linear reduction): The MFN rate phases down in equal annual increments to zero by year 5. As of 2026, these lines should be at or near zero. Covers select machinery parts, automotive components (certain engine parts under 8409, transmission components under 8483), and some plastic resins. This is the category most relevant to Chinese industrial exporters — it's the fastest path to duty-free status for non-ITA goods.
• Category B10 (10-year linear reduction): The MFN rate drops in equal annual steps, reaching zero in 2032. As of year 5 (2026), these lines are approximately halfway to zero. Covers a broad swath of industrial goods: pumps, valves, bearings, electric motors, certain steel products, and most machinery under Chapter 84. For a product with a 3.5% MFN rate in this category, the RCEP rate in 2026 would be roughly 1.75% — a meaningful reduction from the 3.5% baseline.
• Category B15 (15-year linear reduction): Reaches zero in 2037. Covers a larger range of manufactured goods: consumer electronics accessories, optical instruments, measuring devices, and select automotive parts. At year 5, approximately one-third of the MFN rate has been eliminated. For a 3.5% MFN product, the RCEP rate in 2026 is roughly 2.3%.
• Category B21 (21-year linear reduction): The longest phase-out. Reaches zero in 2043. Covers politically sensitive categories where Japan maintains domestic production: certain textiles, apparel items, footwear, leather goods, and some food products. At year 5, the reduction is small — roughly 24% of the original MFN rate — so a 10% textile tariff might be 7.6% under RCEP in 2026. These categories are where the "RCEP hasn't helped yet" complaint comes from.
• Category X (Excluded from elimination): Japan permanently excluded certain agricultural products, rice, some fishery products, and specific processed foods from any RCEP reduction. These goods continue to pay full MFN rates indefinitely. If your product is in Category X, RCEP gives you nothing — budget the full MFN rate for the life of the agreement.

The practical takeaway for a Chinese exporter in 2026: RCEP is already delivering real duty savings on industrial machinery and components (Categories B5 and B10). Consumer goods and textiles will take years longer (B15 and B21). The only way to know your exact RCEP rate is to look up your 9-digit HS code in Japan Customs' annual RCEP tariff schedule, published in English at customs.go.jp. Don't assume RCEP applies to your product — it might, at a partial rate, or it might not at all. And remember: RCEP rates are preferential rates that require a valid RCEP Certificate of Origin from the Chinese exporter. If you don't present the cert at clearance, Japan Customs defaults to the MFN rate regardless of what the schedule says.

Japanese Product Compliance and Labeling

Tariffs are only half the equation. Japan enforces extensive product safety and labeling rules. For electronics, the PSE mark — Product Safety of Electrical Appliance & Materials — is mandatory for devices from power adapters to LED lighting. METI, the Ministry of Economy, Trade and Industry, enforces strictly: non-compliant goods face denial of entry, tariff paid or not.

The JIS (Japanese Industrial Standards) system provides voluntary specs, but compliance is a de facto market-access requirement — Japanese buyers will not purchase uncertified goods. The Household Goods Quality Labeling Act mandates Japanese-language labeling on all consumer products. For food-contact materials — kitchenware, food containers — the Food Sanitation Act requires MHLW third-party testing and certification before customs will release the shipment. Testing alone can add weeks to clearance.

RCEP is reducing tariffs on Chinese goods through a 16-category elimination schedule with timelines ranging from immediate (Category A, already at zero since 2022) to 21-year phase-outs (Category B21, reaching zero in 2043). As of June 2026 (year 5), industrial machinery and components in Categories B5 and B10 are seeing meaningful reductions — many B5 lines are near zero, B10 lines roughly halfway there. Consumer goods and textiles in B15 and B21 are moving slowly; Category X products (agriculture, rice, certain processed foods) are permanently excluded. See the detailed category-by- category breakdown in the RCEP Tariff Elimination section above for exact reduction rates and timelines. Always check your 9-digit HS code against Japan Customs' annual RCEP schedule — and remember that RCEP preferential rates require a valid RCEP Certificate of Origin presented at clearance.

Do I need a Japanese importer of record?

Yes. Non-resident entities must engage either a Japan-domiciled importer of record (IOR) or a licensed customs broker — a tsuukangyou — acting as the IOR. The IOR is legally responsible for the accuracy of the declaration and for remitting all duties and taxes. For Amazon FBA Japan, this is absolute: the platform rejects inbound inventory without a Japanese IOR on file. Many sellers work with Japan IOR service providers who handle clearance, JCT remittance, and compliance for a per-shipment or monthly fee.
