Can Power Banks Be Mailed? Complete Rules for Shipping Lithium Batteries to Taiwan
Power banks cannot be sent by post: under Article 37 of the Regulations Governing the Handling of Mail (郵件處理規則), Chunghwa Post lists lithium batteries as prohibited dangerous goods, and neither domestic nor international mail accepts them. Before sending one within Taiwan by convenience-store or home delivery, ask the carrier first and disclose that it contains a lithium battery. From mainland China to Taiwan you can use consolidated shipping: power banks themselves (UN3480) cannot go on passenger aircraft, so they go by Sea Express only, with a UN38.3 test report attached.
Last updated: 2026-10-11 ｜ Sources: Article 37 of the Regulations Governing the Handling of Mail (郵件處理規則) and Chunghwa Post’s “Classification Table of Prohibited Dangerous Goods”, the Civil Aviation Act (民用航空法), IATA Battery Guidance Document (2026), Civil Aviation Administration, Ministry of Transportation and Communications (passenger carry-on baggage rules), the Commodity Inspection Act (商品檢驗法) and the Regulations Governing Exemption from Inspection of Commodities (商品免驗辦法), Bureau of Standards, Metrology and Inspection (BSMI) inspection-exemption customs clearance codes, the Waste Disposal Act (廢棄物清理法), and Customs Administration, Ministry of Finance (Customs Import Tariff open data)
Can Power Banks Be Mailed? Does the Post Office Accept Them?
No. Chunghwa Post classifies lithium batteries as prohibited dangerous goods and does not accept them in either international or domestic mail. To ship them from mainland China back to Taiwan, you can use consolidated shipping if they comply with regulations and come with UN38.3 or other supporting documentation: power banks themselves and products with built-in lithium batteries all go by Sea Express, and under HowBridge’s acceptance rules they do not go by air.
Under Article 37, Subparagraph 3 of the Regulations Governing the Handling of Mail, flammable, explosive, or other dangerous articles may not be mailed. Chunghwa Post’s “Classification Table of Prohibited Dangerous Goods” lists lithium batteries as miscellaneous dangerous goods, so neither power banks nor loose lithium batteries may be sent as ordinary mail; the same applies to mail sent to mainland China. In addition, under Article 112-2 of the Civil Aviation Act (民用航空法), anyone who violates Article 43, Paragraph 1 by carrying or checking dangerous goods onto an aircraft is subject to a fine of NT$20,000 to NT$100,000, imposed by the Aviation Police Bureau.
| Shipping Method | Can Power Banks Be Shipped? | Basis／Requirements |
|---|---|---|
| Chunghwa Post International／Domestic Mail | Not accepted | Under Article 37, Subparagraph 3 of the Regulations Governing the Handling of Mail; Chunghwa Post’s Classification Table of Prohibited Dangerous Goods lists lithium batteries as “miscellaneous dangerous goods” |
| Mail to mainland China | Not accepted | The same prohibited dangerous goods rules apply (lithium batteries are miscellaneous dangerous goods) |
| Consolidation: Air | No air for battery items | Under HowBridge’s acceptance rules, products containing lithium batteries (including built-in batteries) do not go by air; under international rules, power banks themselves (UN3480) are also prohibited on passenger aircraft |
| Consolidation: Sea Express | Accepted with conditions | Both power banks themselves and products with built-in lithium batteries go by Sea Express; must comply with regulations and come with a UN38.3 test report or other supporting documentation |
| Convenience-store pickup／home delivery within Taiwan | Rules vary by carrier | We have found no official written policy from these carriers; check with the carrier before sending and proactively disclose that the contents include lithium batteries |
The difference is whether dangerous-goods declaration and documentation procedures are followed. Under the Regulations Governing the Handling of Mail, dangerous articles are prohibited from the mail as an entire category; consolidated shipping, by contrast, requires the seller to provide a UN38.3 test report or other supporting documentation, proper packaging, and a truthful declaration, so that lithium batteries can be transported in accordance with the rules. If a power bank is falsely declared as ordinary goods and hidden in a shipment, the parcel will be intercepted; concealing dangerous goods and bringing them onto an aircraft may also be penalized under the Civil Aviation Act provisions described above.
If batteries are imported on a commercial scale, responsible businesses must pay a recycling, clearance, and disposal fee under Articles 16 and 16-1 of the Waste Disposal Act (廢棄物清理法), at the rates approved and announced by the central competent authority; the rates announced by the Ministry of Environment prevail. This does not apply to personal use.
To compare consolidation methods for different battery-containing products, such as Bluetooth earphones, self-balancing scooters, and battery-powered toys, see the Complete Guide to Consolidating Lithium Battery Products. For shipping rules on mobile phones, laptops, earphones, and other battery-containing consumer electronics, see the Complete Guide to Consolidating 3C Products.
Shipping Power Banks Within Taiwan: Can You Use the Post Office, 7-11, or Home Delivery?
Chunghwa Post’s domestic mail does not accept power banks or lithium batteries either (Article 37, Subparagraph 3 of the Regulations Governing the Handling of Mail; Chunghwa Post’s Classification Table of Prohibited Dangerous Goods lists lithium batteries as miscellaneous dangerous goods). Whether convenience-store shipping (such as 7-ELEVEN’s store-to-store service) and home delivery accept lithium batteries varies by carrier, and we have found no official written policy; check with the carrier before sending and proactively disclose that the contents include lithium batteries.
Can Power Banks Bought on Taobao or in Mainland China Be Shipped to Taiwan?
Yes, but not by post or as an ordinary parcel—they must comply with regulations and come with supporting documentation. Power banks are Class 9 dangerous goods. Under international rules, those not installed in equipment (UN3480) are prohibited from being carried as cargo on passenger aircraft regardless of Wh, so at HowBridge power banks themselves are shipped by Sea Express only; under HowBridge’s acceptance rules, lithium batteries installed in equipment (UN3481) likewise go by Sea Express, not by air. In both cases, the seller must be able to provide a UN38.3 test report or other supporting documentation. Chunghwa Post lists lithium batteries as prohibited dangerous goods, so mail to or from mainland China does not accept them either.
Why Do Taobao Sellers Often Say “Can’t Ship to Taiwan”?
One common reason is that the courier the seller works with does not accept battery-powered goods; it does not necessarily mean Taiwan bans the import—which is a separate question from whether the product itself is legal (further reading: the “not available for sale in Taiwan” section of Items That Can’t Be Shipped from Taobao to Taiwan). In Taiwan, power banks are not prohibited imports but fall in the “inspection required” tier: the import regulation for Customs Import Tariff code 8507.60.00.10-7 is C02 (some goods under this item are commodities subject to import inspection as announced by the Bureau of Standards, Metrology and Inspection, Ministry of Economic Affairs), and under Article 6 of the Commodity Inspection Act (商品檢驗法), commodities subject to inspection that do not meet inspection requirements may not be imported; imports for personal use may be exempt when the conditions are met. In practice, have the item sent to the consolidation warehouse, ask our customer service before ordering and state that it contains a battery; once we have confirmed the documents, we will arrange Sea Express instead of bundling it with ordinary parcels.
Should Batteries Go by Sea Express or by Air? How to Choose
Anything containing a lithium battery goes by Sea Express. Under international rules, power banks themselves and loose batteries (UN3480) cannot be carried on passenger aircraft; under HowBridge’s acceptance rules, lithium batteries installed in equipment (UN3481, such as mobile phones, laptops, and Bluetooth earphones) likewise do not go by air and always go by Sea Express. Either way, the shipment must comply with regulations and come with a UN38.3 test report or other supporting documentation; please check with our customer service before shipping.
How Much Tax Do You Pay When Importing from Mainland China?
Power banks fall under tariff code 8507.60.00.10-7 with a general duty rate of 2.5%; imports from mainland China that meet the ECFA rules of origin and are applied for with a certificate of origin may qualify for 0% (in practice, ECFA is usually not claimed for small personal parcels, so do not assume 0% in every case). A shipment with a customs value (CIF) ≤ NT$2,000 is exempt from customs duty and business tax (limited to 6 times per person per half-year); above that threshold, customs duty and 5% business tax apply. BSMI personal-use inspection exemption: whether the information technology equipment code (CI000000000010, ≤ US$1,000, or more than that but ≤ 5 pieces) or the general code (CI000000000002, ≤ US$1,000 only) applies depends on how the Bureau of Standards, Metrology and Inspection classifies the actual product.
⚠️ Note: this section covers consolidated shipping. If you are a traveler bringing a power bank back to Taiwan yourself, an entirely different set of rules applies—from April 8, 2026 (ROC year 115), each passenger may carry no more than 2 power banks; they may not be checked in, used, or charged on board (this quantity limit applies alongside the 100Wh／160Wh tiers); see Can It Be Shipped by Air? and the Wh reference table below.
Can My Power Bank Be Shipped by Air? How to Determine
It depends on whether you are “carrying it as a passenger” or “shipping it through a consolidation service”: carry-on rules depend on Wh (≤100Wh is permitted, 100~160Wh requires airline approval and is limited to 2 units, and 160Wh and above may not be carried under international rules—check with your airline); for consolidated shipments, regardless of Wh, power banks themselves go by Sea Express only and require UN38.3 or other supporting documentation.
✅ Common Retail Capacities (≤ 100Wh, Approximately 27,000mAh or Less)
Eligible for Consolidation
Ship them through consolidation by Sea Express, with a UN38.3 test report or other supporting documentation prepared; outbound passengers may also carry power banks onto an aircraft (they cannot be checked in), but from April 8, 2026 (ROC year 115), each passenger is limited to 2 power banks and may not use or charge them on board. The vast majority of commercially available power banks fall into this category.
⚠️ High Capacity (> 100Wh)／Loose Batteries
Carry-On Restricted > 160Wh Prohibited as Carry-On
Passenger carry-on: power banks rated 100–160Wh require airline approval and are limited to 2 units; 160Wh and above may not be carried under international rules—check with your airline. A separate quantity rule also applies: from April 8, 2026 (ROC year 115), each passenger may carry no more than 2 power banks and may not use or charge them on board—this quantity limit applies alongside the 100Wh／160Wh tiers. Consolidated shipping: regardless of Wh, power banks themselves and loose batteries always go by Sea Express and require UN38.3 or other supporting documentation.
How Do You Calculate a Power Bank's Wh?
Enter the capacity and voltage to calculate the watt-hours (Wh) and applicable carry-on／consolidated-shipping rules instantly. Formula: Wh = mAh × V ÷ 1000.
※ Calculations based on nominal voltage are for reference only. The Wh marked on the product and the rules of the airline and carrier shall govern. Lithium battery transport must comply with UN38.3 and other applicable requirements.
Wh Limits and Capacity Reference Table
Calculated at 3.7V: 10,000mAh is approximately 37Wh, 20,000mAh is approximately 74Wh, and 26,800mAh is approximately 99Wh. Capacities of approximately 27,000mAh and above exceed 100Wh, while capacities of approximately 43,300mAh and above exceed 160Wh.
| Power Bank Capacity (3.7V) | Approximate Wh | Passenger Carry-On｜Consolidated Shipping |
|---|---|---|
| 10,000mAh | Approximately 37Wh | Permitted as carry-on｜Consolidated shipments go by Sea Express |
| 20,000mAh | Approximately 74Wh | Permitted as carry-on｜Consolidated shipments go by Sea Express |
| 26,800mAh | Approximately 99Wh | Permitted as carry-on (near the 100Wh limit)｜Same consolidated-shipping rules as above |
| Approximately 27,000mAh or Above | > 100Wh | Carry-on requires airline approval and is limited to 2 units｜Consolidated-shipping rules remain unchanged (Sea Express) |
| Approximately 43,300mAh or Above | > 160Wh | Not allowed as carry-on under international rules (check with your airline)｜Consolidated shipments go by Sea Express (supporting documentation required—please check with customer service first) |
The 100Wh/160Wh tiers come from the Civil Aviation Administration’s rules for passengers’ carry-on baggage; they apply to passengers traveling by air, not to freight or postal shipments (power banks may not be placed in checked baggage). The Civil Aviation Administration also stipulates that, from April 8, 2026 (ROC year 115), each passenger may carry no more than 2 power banks and may not use or charge them on board (this quantity limit applies alongside the 100Wh／160Wh tiers). For freight: power banks or loose batteries not installed in equipment (UN3480), regardless of Wh, are prohibited from being carried as cargo on passenger aircraft and may only be transported on cargo-only aircraft (SoC ≤ 30%) or by sea; for lithium batteries installed in equipment (UN3481), cells ≤ 20Wh and batteries ≤ 100Wh fall under the simplified IATA Section II provisions, but they are still dangerous goods and must meet packaging and marking requirements; IATA also recommends shipping batteries installed in equipment at SoC ≤ 30% (not mandatory). HowBridge acceptance rules: products containing lithium batteries (including built-in batteries) always go by Sea Express, not by air. Wh = capacity (mAh) × voltage (V) ÷ 1000; the nominal voltage of most power banks is 3.7V.
HowBridge Key Facts (Free to Cite)

Glossary
- UN3480
- Lithium-ion batteries not installed in equipment (loose batteries); power banks themselves fall into this category. Regardless of Wh, they are prohibited as cargo on passenger aircraft and may travel only on cargo-only aircraft or by maritime transport.
- UN3481
- Lithium-ion batteries installed in equipment or packed with equipment—for example, Bluetooth earphones, cameras, and toys that contain batteries.
- Wh (watt-hour)
- The energy unit for lithium batteries, calculated as Wh ＝ mAh × V ÷ 1000. At 3.7V, 20,000mAh is about 74Wh.
- SoC (state of charge)
- State of Charge: the battery’s remaining charge expressed as a percentage. When lithium batteries are shipped by air on all-cargo aircraft, SoC must be kept at 30% or below.
- UN38.3
- The lithium battery transport safety test set out in Section 38.3 of the UN Manual of Tests and Criteria for the transport of dangerous goods; lithium batteries shipped by air must have this test report.
- IMDG Code
- International Maritime Dangerous Goods Code (IMDG Code): the international rules for transporting dangerous goods by sea; lithium batteries are likewise Class 9 dangerous goods and must meet packaging, marking, and UN38.3 requirements.
Should Lithium Batteries Go by Sea Express or by Air?
Anything containing a lithium battery goes by Sea Express. Under international rules, power banks themselves and loose batteries cannot be carried on passenger aircraft; under HowBridge’s acceptance rules, lithium batteries installed in equipment likewise do not go by air. Both require UN38.3 or other supporting documentation and may not be mixed into ordinary parcels.
Lithium batteries are classified as Class 9 dangerous goods and categorized by battery configuration: loose batteries (UN3480), batteries contained in equipment (UN3481), and batteries packed with equipment (UN3481). Consolidated shipments are arranged by battery type:
| Method | Requirements | Suitable For |
|---|---|---|
| Air | Under HowBridge’s acceptance rules, products containing lithium batteries (including built-in batteries) do not go by air; under international rules, power banks themselves (UN3480) are also prohibited on passenger aircraft | Not available for lithium-battery items |
| Sea Express | Governed by the IMDG Code; lithium batteries are likewise Class 9 dangerous goods and must meet packaging, marking, and UN38.3 requirements | Power banks themselves, loose batteries, and consumer electronics containing batteries |
Products containing lithium batteries, such as power banks, Bluetooth earphones, self-balancing scooters, and battery-powered toys, cannot be mixed into ordinary parcels; they must comply with regulations and come with a UN38.3 test report or other supporting documentation. HowBridge acceptance rules: power banks themselves and products with built-in lithium batteries always go by Sea Express, not by air; before placing an order, please check with our customer service and let us know the product contains a battery. If the shipping-fee calculator on this page shows an air option, it does not apply to products containing lithium batteries; Sea Express is NT$50 per unit, charged on the greater of actual weight and volumetric weight (L × W × H in cm ÷ 10000), rounded up, with a delivery fee of NT$100 added when the actual weight is under 10 kg.
Do Imported Power Banks Require BSMI Certification?
Inspection is required for sale, while imports for personal use are generally eligible for exemption. The common exemption threshold is a total value of US$1,000 or less for goods of the same specification and model on the same declaration. Whether an exemption remains available above that value and which inspection-exemption customs clearance code should be declared depend on the product’s actual category. Confirm with a customs broker or BSMI before customs declaration.
The Bureau of Standards, Metrology and Inspection, Ministry of Economic Affairs announced the “Inspection Requirements for 3C Secondary Lithium Cells／Batteries, Secondary Lithium Power Banks, and Battery Chargers Subject to Inspection,” effective May 1, 2014 (ROC year 103) (according to media reports; the link to BSMI’s original announcement is pending). Since then, power banks have been commodities subject to inspection, and businesses must pass BSMI inspection and obtain commodity certification registration before selling them. Personal-use imports may qualify for inspection exemption under the following conditions:
Under Article 5 of the Regulations Governing Exemption from Inspection of Commodities, personal-use goods not intended for sale may be exempt from inspection if the total value of goods of the same specification and model on the same declaration is US$1,000 or less. The value is calculated using the cost, insurance, and freight value (CIF), and goods of the same specification and model covered by multiple declarations on the same import date must be aggregated.
BSMI’s “List of Common Inspection-Exemption Customs Clearance Codes” specifies different codes and conditions by product category—for example, CI000000000010 applies to information technology equipment (≤ US$1,000, or more than that but no more than 5 pieces), while CI000000000002 applies to goods not covered by a dedicated category (total value of goods of the same specification and model on the same declaration of US$1,000 or less, with no quantity limit; the code list took effect on April 1, 2019 (ROC year 108)). Although the inspection standards for power banks include the CNS 14336-1 safety standard for information technology equipment, the code to declare must be determined according to the product’s actual classification at the time of customs declaration. Confirm with a customs broker or BSMI rather than applying a code on your own.
If the goods do not qualify for inspection exemption and no approval document from the Bureau of Standards, Metrology and Inspection is available, they may not be imported under Article 6 of the Commodity Inspection Act. Business-side liability: under Article 60 of the same Act, an inspection applicant who exports, imports, or places on the market commodities that do not meet inspection requirements is subject to a fine of NT$200,000 to NT$2,000,000. We recommend choosing a power bank that has obtained BSMI commodity certification registration.
Frequently Asked Questions
No. Under Article 37, Subparagraph 3 of the Regulations Governing the Handling of Mail, flammable, explosive, or other dangerous articles may not be mailed; Chunghwa Post’s “Classification Table of Prohibited Dangerous Goods” lists lithium batteries as miscellaneous dangerous goods, so neither domestic nor international mail accepts them, and the same applies to mail sent to mainland China. In addition, under Article 112-2 of the Civil Aviation Act, anyone who violates Article 43, Paragraph 1 by carrying or checking dangerous goods onto an aircraft is subject to a fine of NT$20,000 to NT$100,000. To ship them from mainland China back to Taiwan, you can use consolidated shipping instead: if they comply with regulations and come with UN38.3 or other supporting documentation, power banks themselves and products with built-in lithium batteries all go by Sea Express and, under HowBridge’s acceptance rules, do not go by air.
Chunghwa Post’s domestic mail does not accept power banks or lithium batteries either (Article 37, Subparagraph 3 of the Regulations Governing the Handling of Mail; Chunghwa Post’s Classification Table of Prohibited Dangerous Goods lists lithium batteries as miscellaneous dangerous goods). Whether convenience-store shipping (such as 7-ELEVEN’s store-to-store service) and home delivery accept lithium batteries varies by carrier, and we have found no official written policy; check with the carrier before sending and proactively disclose that the contents include lithium batteries.
Yes, but only under certain conditions. Power banks are lithium batteries not installed in equipment (UN3480). Under ICAO／IATA rules, they are prohibited from being carried as cargo on passenger aircraft regardless of Wh, so at HowBridge they are shipped by Sea Express only, and the seller must provide a UN38.3 test report or other supporting documentation. The 100Wh／160Wh classifications apply to passenger carry-on baggage, not cargo-shipping thresholds.
Wh = capacity (mAh) × voltage (V) ÷ 1000. Most power banks have a nominal voltage of 3.7V. For example, 10,000mAh is approximately 37Wh, 20,000mAh is approximately 74Wh, and 27,000mAh is approximately 100Wh.
Products intended for sale must pass BSMI inspection. For personal-use imports, under Article 5 of the Regulations Governing Exemption from Inspection of Commodities, goods of the same specification and model on the same declaration may be exempt from inspection if their total value is US$1,000 or less (calculated on a CIF basis, with multiple declarations from the same day aggregated). Whether an exemption remains available above that value and which inspection-exemption customs clearance code should be declared—such as CI000000000010 for information technology equipment or CI000000000002 for goods not covered by a dedicated category—depend on the product’s actual category. Confirm with a customs broker or BSMI before customs declaration.
Yes. Products with built-in or included lithium batteries are also Class 9 dangerous goods (UN3481) and must comply with regulations and come with UN38.3 or other supporting documentation. Under HowBridge’s acceptance rules, products containing lithium batteries (including built-in batteries) always go by Sea Express, not by air; please check with our customer service before shipping.
Power banks fall under tariff code 8507.60.00.10-7, with a general duty rate of 2.5% (imports from mainland China that meet ECFA rules of origin and are applied for with a certificate of origin may qualify for 0%; in practice, ECFA is usually not claimed for small personal parcels, so do not assume 0% in every case). Imports with a customs value of ≤ NT$2,000 are exempt from customs duty and business tax (limited to 6 times per person per half-year); above that amount, customs duty and 5% business tax apply.
Under international rules, loose batteries (UN3480) cannot be carried on passenger aircraft, so at HowBridge they are shipped by Sea Express only, with a UN38.3 test report or other supporting documentation prepared; please check with our customer service before shipping. You may also consider buying a finished product with a built-in battery instead.
