Batteries Exporters in Bangladesh: Verified Supplier Checklist

Use this checklist before you commit to a battery supplier in Bangladesh, not after the order is placed. It is a supplier check, not a product inspection: each item asks for a document, a name, or a written answer to file against the order. Mark each item met, not met, or not applicable, and keep the evidence with the purchase order.

Why this checklist matters

Battery orders fail in ways a price comparison cannot show: evidence for a different model, a quote for a product not made, or a label suited to another market. Because batteries are regulated goods, a paperwork gap can hold a shipment at the border even when the goods are sound. Checking first separates three questions: does this business trade as claimed, does it make or source this exact battery, and can it support labelling, transport, and delivery?

The checklist also protects repeat orders, often placed on trust alone, by giving the second order a baseline: any difference must be explained before shipment.

Before you start

Write down the battery before contacting any supplier: chemistry, primary or rechargeable, size and terminal type, the device it will power, destination country, and transport route. Chemistry decides which standards and transport rules apply, so a vague brief is not enough.

Decide who completes the checklist and who signs it off. On larger orders, the price negotiator should not be the only document checker. Agree that a missing report, a certificate naming a different model, or a label omitting required information stops the order until resolved.

The full checklist (numbered, printable)

A. Identity and trading standing

1. Confirm the legal name, address, and contacts, and check the same name on quotations, invoices, and bank details.

2. Ask what the supplier does for this order: manufacture, assembly, packing, or trading, and what another party does.

3. Ask for the business registration or trade licence, and record its number and expiry date where shown.

4. Ask for two references for similar battery orders, and contact at least one before a first order.

5. Confirm your contact can quote and confirm orders, and record their name and role.

B. Product scope and chemistry match

6. Confirm in writing the exact chemistry, cell type, size, voltage, and capacity, against your specification.

7. Confirm whether the battery is primary or rechargeable, and that the evidence matches that category.

8. Ask whether it ships as loose cells, a finished battery, or a battery inside or packed with equipment.

9. Ask for a datasheet for the exact model, and note any difference from the quotation.

10. Ask what would change for a different size or chemistry, and whether fresh evidence is needed.

C. Standards and test evidence

11. Ask which standard applies, and ask for the report naming the exact model, not a similar one.

12. For primary batteries, IEC 60086-1 covers dimensions, nomenclature, terminals, markings, test methods, performance, safety, and environmental aspects.¹

13. For portable sealed secondary lithium batteries, check for IEC 62133-2 evidence, which sets safety requirements for portable sealed secondary lithium cells and batteries.²

14. Check the laboratory, date, and model on each report, and file the report itself, not a summary alone.

15. Ask whether any certificate or report has conditions, limits, or expiry, and record them.

16. If a national mark is claimed, ask for its licence. Lead-acid traction batteries were brought under the Bangladesh Standards and Testing Institution mandatory quality certificate system.³

D. Factory and production control

17. Ask how production is controlled: incoming, in-process, and final checks before packing.

18. Ask how traceability works: how a battery or carton traces to its cell batch and date.

19. Ask how a failed batch is handled, and who decides on rework, segregation, or rejection.

20. Ask whether production, assembly, or packing is subcontracted, and who holds the evidence for the finished product.

21. For a first order, ask for dated photos of the actual order, not catalogue images, and check labels and cartons.

E. Commercial terms, MOQ, and price drivers

22. Ask for the minimum order quantity in your order unit, and what changes below or above it.

23. Ask for a price breakdown by cost driver, showing what moves if chemistry, size, quantity, or packing changes.

24. Ask what the price includes: packing, marking, documentation, and delivery to the agreed point, each stated.

25. Ask for the lead time from confirmation, and what events would extend it.

26. Ask for payment terms, and confirm the bank name matches the legal name in section A.

F. Labelling and destination market

27. Ask for a label proof for the exact battery and market before bulk labelling, and check name, category, capacity, chemistry, and safety information.

28. For the European Union, Regulation (EU) 2023/1542 applies to all battery categories placed on the Union market, whether made there or imported.⁴

29. For the European Union, CE marking, where required, must be affixed visibly, legibly, and indelibly to the battery, or to packaging and documents where that is not possible.⁴

30. Ask who owns destination-market compliance: supplier, importer, or a shared split, and record it.

31. Ask for the declaration of conformity, and check it names the Regulation or standard claimed.

G. Transport, by chemistry

32. For lithium only, ask for the UN 38.3 test summary for the exact type; UN 38.3 covers eight tests, T1 to T8.⁵

33. For lithium only, confirm the UN number with the forwarder: alone, contained in equipment, or packed with equipment.⁵

34. For non-lithium chemistries, do not accept a lithium test summary as transport evidence. Ask the forwarder to confirm the correct classification, packing, and marking in writing.

35. Ask for the safety data sheet for the exact chemistry offered, and check its product name and chemistry match the order.

H. Packing and shipment documents

36. Ask for a packing specification: carton contents, marking, pallet plan where used, and protection against short circuits and damage.

37. Ask which documents will be supplied: invoice, packing list, certificate of origin where required, test evidence, and safety data sheet, each named before shipment.

38. Confirm classification with your broker: primary cells and batteries fall under heading 8506, by chemistry, while rechargeable accumulators fall under a different heading.⁶

39. Ask how cartons will be marked for checking against the packing list on arrival: model, quantity, and batch.

I. Change control and escalation

40. Agree in writing that any change to cell source, chemistry, capacity, pack design, labelling, or packing is notified before shipment, with fresh evidence where it affects a standard or transport rule.

41. Agree a single contact for quality problems and a written complaint route, including faulty-goods handling and return costs.

42. Record the result: items met, items not applicable and why, and items to close before confirmation.

Common failures and how to fix them

The most common failure is a certificate belonging to a different product: a report naming a similar size, an earlier model, or a cell rather than the finished battery. Stop at section C and ask for the report naming the exact model. If it cannot be produced, treat the item as not met.

The next failure is a chemistry mismatch in transport: a lithium summary offered for a non-lithium order. The fix is section G: separate the chemistries, and get forwarder confirmation in writing for the chemistry shipped. A label written for one market and shipped to another is caught by section F at proof stage, before bulk labelling locks it in.

A third failure is a price agreed before the specification is fixed. When size, packing, or documentation are added later, price or lead time moves. The fix is section E: settle the specification, packing, and document list first, then agree the price against that list. Where a supplier cannot answer a section, the order needs a different supplier, a third-party check, or a smaller first order.

FAQs

When should this checklist be used?

Use it before a first order, and again when chemistry, size, supplier, or market changes. For unchanged repeat orders, re-check sections C, F, and G.

Who should complete it?

The buyer, a buying agent, or an independent inspector can complete it, provided the checker is not also the only person negotiating price. Share the specification and destination market with the checker first.

What are the most common failures?

A certificate naming a different model, a transport document for the wrong chemistry, a label for another market, and a price agreed before packing and documentation were fixed.

Can a third party do it?

Yes, if you share the full specification, destination market, and this checklist before the check starts, and if the third party files the evidence relied on, not a pass mark alone.
