404 temporary tariff lines expire at the end of March 2027; multi-year periods under discussionTalks on reviewing the time-limited tariff rates on imported goods
On November 6 the Ministry of Finance submitted a paper, Review of the application period of temporary tariff rates, to the Customs Subcommittee of the Council on Customs, Tariff, Foreign Exchange and Other Transactions. It states that a decision is needed on 404 tariff lines whose temporary rates expire on March 31, 2027, and asks whether, for lines where the temporary character and the basis for the rate level are durable, the period might be set at several years rather than the single year used until now. This is a paper at the discussion stage and nothing has been decided.
Key points
- The paper defines a general tariff rate as a rate set from a medium- to long-term viewpoint, taking account of internal and external price gaps and the level of protection genuinely needed, and a temporary tariff rate as a rate that temporarily modifies the general rate for policy reasons, with a set expiry date
- 404 tariff lines expire on March 31, 2027: 13 lines under tariff quotas introduced before the Uruguay Round agreement took effect, 144 lines set to provide market access under that agreement, 86 lines under the state trading system, 99 lines at levels below the agreed rate or subject to adjustment levies, 54 lines reflecting consultations with partner countries, and 8 lines based on industrial policy needs
- The one-year period reflects the idea that the judgement should be made afresh each time, but some lines have been extended over many years, and the paper records a comment made in the subcommittee asking whether it is normal for rates to stay temporary while being extended every year for many years
- As a reference for multi-year periods, the paper notes that the first opportunity to modify bound rates under the WTO agreement comes in January 2030 (Reiwa 12). Other periods under the Temporary Tariff Measures Act are one year for the special safeguard duty, two years for the optional taxation system for Okinawa, three years for the designated duty-free shop system for Okinawa and for the duty exemption on aircraft parts and the reduced duty on re-imported processed goods, and ten years for preferential tariffs
- The number of lines carrying temporary rates has fallen from 416 in fiscal 2019 to 404 in fiscal 2026; in fiscal 2026 the removal of temporary rates on naphtha for petrochemical production, kerosene and gas oil cut eight lines
What to do in practice
- Check on your customs documents whether the rate applied to the goods you import is the general rate, a temporary rate or the agreed rate
- If any of your goods carry a temporary rate, work on the basis that it expires on March 31, 2027 and follow the fiscal 2027 tariff revision as it is announced
When you buy goods abroad and bring them into Japan, a tax called a tariff applies. Tariffs come in two kinds: a general rate used over the long term, and a temporary rate that replaces it for a set period. On November 6 the Ministry of Finance put a paper to a council meeting on what to do with 404 lines whose temporary rates run out on March 31, 2027. At present they are renewed a year at a time, and the talks included setting them for several years instead. Nothing has been decided.
Points
- Tariff rates come in two kinds: a general rate used over the long term, and a temporary rate with an expiry date
- 404 lines have temporary rates that run out on March 31, 2027
- Until now they have been renewed a year at a time; setting them for several years is one idea on the table, but nothing is settled
What the words mean
- tariff
- A tax charged when goods bought abroad are brought into Japan
- temporary tariff rate
- A rate that replaces the general rate for a time, with an expiry date set in advance
