Terms & conditions:the commercial ground rules from quotation to warranty

These terms cover every supply of motive battery packs, swap modules, retrofit kits and related technical documents from TIANQIU to overseas companies and fleet operators. This page is a general statement and is not an offer or a commitment.
Where clauses conflict, the order of precedence is: the signed contract and its annexes → the purchase order and proforma invoice → this general page. Anything here that conflicts with a signed contract is superseded by that contract.

Quotations are modelled on the four inputs you supply: destination port, payload, daily distance and motor rating. They can be issued as EXW, FOB or CIF, and a Form E certificate of origin can ship with the container.
A quotation is valid for 14 calendar days from issue, and any production capacity reserved at your request is held for the same 14 days. Past that window — or if cell and material prices, freight rates or carrier space policy move materially — we re-price and confirm in writing. Orders already under a signed contract are unaffected.

Samples and trial orders: formed when both parties confirm the sample specification, quantity and price and you pay the sample amount.
Container orders: formed when both parties sign the contract (or seal and return the proforma invoice) and the deposit stated in it is paid.
Discussions at a trade show, messages in a chat app, preliminary email confirmations, inquiry registrations and reserved capacity quotas do not form a contract; they are pre-signing correspondence only.

The usual instruments are telegraphic transfer (T/T) and letter of credit (L/C); the currency, bank details and milestones are set out in the contract. The standard pattern is a deposit on signature and the balance before shipment, or against a copy of the bill of lading.
Credit terms are offered only to contracted, credit-assessed long-term customers, with the limit, tenor and any security agreed in writing. Orders with no credit terms in the contract follow the standard milestones above. Interest on late payment or penalty rates are not set on this page and follow the contract.

Sampling takes about 3–5 days from specification confirmation and receipt of the sample payment. Container lead times quoted at confirmation are an estimate and are not a fixed-date commitment.
Lithium batteries are dangerous goods, so space is limited by each carrier’s DG allocation and route policy: the actual sailing date is confirmed when the carrier confirms the booking. If a vessel closes out, skips a port or is rescheduled, we notify you in writing immediately and arrange the next available sailing. Reference loading: about 180 units per 20GP and 320+ per 40HQ, reconfirmed against the actual model and packaging.

The standard commercial warranty is 5 years / 3,500 cycles, counted from the earlier of the factory barcode scan and the BMS activation timestamp. If a standard test within that period shows usable capacity below 80% SOH, the case is treated as warranty and the module is replaced free of charge.
Covered and excluded cases (impact-broken enclosures with water ingress, use of a non-compliant charger and similar) plus the claim workflow are set out in warranty terms and the RMA process, which this page follows. If a contract annex states a different term or test standard, the annex governs.

We are responsible for the quality of our own products and for our own delivery obligations. To the extent the law allows, we are not liable for indirect losses arising from a battery being out of service or from a delayed delivery, including lost operating days, substitute transport costs, lost profit and loss of goodwill.
Any cap on total compensation, the scope of liability and the recovery mechanism follow the signed contract. This page sets and implies no specific compensation amount or percentage.

A party prevented from performing, or delayed in performing, by force majeure is not in breach. Events include natural disasters, war and regional conflict, strikes and terminal stoppages, epidemics and government control measures, export controls and trade policy changes, port closures, carrier suspensions or omitted calls, and destination-port congestion or mandatory inspection.
The affected party must notify the other in writing within a reasonable time and provide such evidence as is available; the parties then agree a revised schedule or delivery arrangement according to the impact. How to proceed if the event lasts beyond an agreed period is set by the contract.

TIANQIU’s brand, product designs, structural drawings, BMS firmware and supporting technical documents belong to us or the relevant rights holder; they may not be copied, resold or used to imitate a product for a third party without written permission.
For custom enclosures, dedicated brackets and bespoke tooling developed against your vehicle and battery box, ownership, scope of use and subsequent disposal follow the contract. Where tooling costs are charged, the contract should state who stores the tooling and the conditions for its use and transfer.

Governing law: these terms and any contract formed under them are governed by the laws of the People’s Republic of China.
Disputes: the parties first negotiate in good faith; failing that, the dispute is submitted to the competent authority in Guangzhou. That is our standard wording and it is negotiable — the signed contract always governs, and if it names another governing law or arbitral body, that applies instead.
Amendments: this page may be revised as the business and regulations evolve. Revisions apply to new quotations and orders from the date of publication; rights and obligations under a signed contract are unaffected.
