CPTPP Savings: Primary Batteries & Cells (HS 8506)
Two lines carry a real 7% MFN duty — one of them lithium batteries that are also DGR-classified cargo, independent of the duty question.

CPTPP rate
HS 8506 covers primary cells and primary (non-rechargeable) batteries. Cells with welded connectors for electronic locks and smoke-detector batteries are already Free at MFN; other manganese dioxide cells and other lithium (primary) batteries carry a 7% MFN duty CPTPP eliminates.
Part of our Dangerous Goods Cargo commodity guide →What actually qualifies: tariff shift or regional value content
Manufactured goods generally qualify under CPTPP's product-specific rules of origin through either a tariff-shift test — the finished good must be classified under a different HS heading than any non-originating materials used to make it — or a regional value content (RVC) threshold, typically 30–40% under CPTPP, notably more lenient than NAFTA's old 50–60% requirement.
Unlike the textile yarn-forward rule or produce's wholly-obtained test, this means a part can incorporate some non-CPTPP-origin materials or components and still qualify, provided the specific tariff-shift or RVC threshold for that HS heading is met. Confirm the applicable rule for the specific heading rather than assuming any manufacturing location automatically qualifies.

Tariff lines with a real CPTPP saving
Only the codes under HS 8506 that actually carry an MFN rate above zero — lines already Free at MFN aren't shown here since there's no saving to claim.
| HS Code | Description | MFN | CPTPP |
|---|---|---|---|
| 8506.10.90 | Other manganese dioxide cells | 7% | Free |
| 8506.50.90 | Other lithium batteries (primary, non-rechargeable) | 7% | Free |
CPTPP Rate Claim
Confirm origin eligibility before claiming the CPTPP rate on HS 8506
Claiming the CPTPP rate requires confirming the good actually meets its product-specific rule of origin — not just that it shipped from a CPTPP member country. See the origin test above before booking a shipment against this rate.

Frequently asked questions
No — the CPTPP duty treatment and the IATA DGR classification (UN 3090/3091, lithium metal) are entirely separate. A lithium primary battery shipment still needs the correct Packing Instruction and declaration regardless of what duty rate applies. See our dangerous goods commodity page and lithium battery guide for that side.
