What import notification does a tea or matcha shipment need before it can clear a Japanese port?
Every commercial shipment needs an Import Notification filed with Japan’s Ministry of Health, Labour and Welfare before it can be sold or used in business. Article 27 of the Food Sanitation Act makes the notification a condition of sale, not a formality.
The notification is filed at the quarantine station covering the port of entry, where food sanitation inspectors examine the accompanying documents and decide whether the consignment also needs an on-site or laboratory inspection before a Certificate of Notification is issued (accessed 2026-09-25, Ministry of Health, Labour and Welfare). A shipment that reaches a Japanese port without this step cannot legally be sold, no matter how clean its residue-test paperwork looks.
What import duty applies to green tea and matcha shipped from China to Japan?
It depends on the tariff line, not just the product. Japan Customs lists green tea in immediate packings of 3kg or less at a 20% general duty, while the WTO rate recorded for the same tariff line is 17%.
Under heading 09.02 of Japan’s Tariff Schedule, effective April 1, 2026, matcha and green tea fall under subheadings 0902.10 and 0902.20 — both carrying the same 20% general duty and 17% WTO rate whether the tea is packed for retail or shipped in bulk (accessed 2026-09-25, Japan Customs Tariff Schedule). A buyer who assumes a bulk shipment automatically earns a lower duty than a retail-packed one is reading the wrong tea category.
Black tea on Japan’s Tariff Schedule shows the opposite pattern for bulk shipments: subheading 0902.30 (black tea in packings of 3kg or less) carries the same 20% general duty as green tea, with a 12% WTO rate for black tea specifically, while black tea presented outside that packing threshold under 0902.40 drops to a 5% general duty and a 3% WTO rate (accessed 2026-09-25, Japan Customs). The same schedule also carries a dedicated “China (RCEP)” rate column: it is blank for tea in retail packings, but shows a Free rate for black tea outside that packing threshold under 0902.40, so a bulk black-tea shipment with a valid RCEP certificate of origin can clear at 0% instead of the 3% WTO or 5% general rate.
What must a Chinese tea producer register before it can legally export to Japan?
A customs filing inside China, first. Export food producers have had to register with the customs office at their place of business since January 1, 2022, under GACC Order No. 249, before their first shipment can leave the country.
Article 42 of GACC Order No. 249, China’s Measures for the Administration of Import and Export Food Safety, requires export food producers to file with customs at their place of domicile, with the filing procedure itself set by China’s General Administration of Customs (accessed 2026-09-25, State Council Gazette). A producer who cannot state a filing reference has skipped a legal step, not an optional one.
Article 46 of the same order goes further: registered producers must mark their customs filing number, product name, production batch number and production date directly on the outer transport packaging of every export shipment (accessed 2026-09-25, GACC Order No. 249). That marking is a detail a buyer can check on the carton itself, before the goods ever reach a Japanese port.
How can a Japanese buyer verify a Chinese tea or matcha supplier before signing a contract?
Four separate checks, not one. A supplier who passes a factory tour can still fail on customs filing, import-notification readiness, tariff classification or label compliance — each is verified against a different authority, not against the supplier’s own claim.
Side-by-side: each checkpoint below traces back to the specific article or schedule that defines it, so a buyer can ask for the document by name rather than by description.
| Checkpoint | What it confirms | How to verify it | Primary basis |
|---|---|---|---|
| Export filing | Producer is legally registered to export food from China | Ask for the customs filing number; cross-check it against the number printed on the shipment’s outer packaging | GACC Order No. 249, Art. 42 & 46 |
| Import-notification readiness | Shipment can actually be declared on arrival in Japan | Ask whether residue-test data and manufacturing records are already assembled, not promised for later | Food Sanitation Act, Art. 27 |
| Tariff classification | Landed cost is calculated on the correct schedule line | Confirm which HS 0902 subheading and which rate column the customs broker will declare | Japan Customs Tariff Schedule, Ch. 9 |
| Label readiness | Packaging is ready for Japan’s shelf requirements | Confirm the origin-country name can be finalized before the product is packed for sale | Food Labeling Standards |
