Busbars for Bangladesh projects, made in India
What it takes to land busbars on a Bangladesh site: the port they clear through, the standards a consultant will hold them to, and the paperwork that has to travel with them.
Getting busbars into Bangladesh
Bangladesh is targeting 30 GW of solar by 2030 and imports most of the mounting structure it needs. Kolkata to Chittagong is a short haul, and that shows up directly in your landed cost rather than in a sales pitch. Freight is the easy part. BNBC compliance is what has to be evidenced document by document.

Busbars into Bangladesh — the questions that come up
Answered by the people who make the product, not a sales desk.
Copper busbar in bar, rod or profile form exports under HS 74071000 (bars, rods and profiles of refined copper). Confirm the exact subheading with your customs broker for your specific cross-section. Buyers shipping to the UAE benefit from 0% duty on HS 7407 under India–UAE CEPA, with a valid Certificate of Origin attached.
Copper busbar sits under HSN 7407 and carries 18% GST domestically. On export it's zero-rated: we ship under an LUT with no IGST charged, or pay IGST and claim the refund back afterward. Whichever route, the buyer's FOB or CIF price carries no Indian tax, only their own country's import duty and VAT.
ETP (Electrolytic Tough Pitch) copper, at 99.9% IACS conductivity or better, is the standard and most economical choice for the vast majority of switchgear, panel and substation busbar work. OFHC (Oxygen-Free High Conductivity) copper is reserved for specialised applications: high-vacuum, cryogenic or ultra-high-purity electronics, and it commands a real premium most power-distribution projects have no reason to pay.
Tin plating protects the copper surface from oxidation and keeps bolted joint resistance stable over the life of the installation. Specify it for outdoor, humid or coastal switchgear, and anywhere joints get made and re-made during maintenance. Bare copper is fine for sealed, indoor, low-humidity panels where cost matters more and joints stay put for years at a time.
IACS stands for International Annealed Copper Standard. 100 % IACS equals a resistivity of 1.7241 µΩ·cm (or 5.8 × 10⁷ S/m). ETP copper tests at 100–102 % IACS; anything below 98 % indicates impurities or cold-work embrittlement, causing the bar to run hotter at rated current. The practical check: ask for resistivity per metre (µΩ/m) rather than a percentage, a 100×10 mm ETP busbar should measure about 0.0172 µΩ/m. If the supplier quotes '>98 %' without a tested value from an NABL lab, that is a red flag. Our NABL-certified test report states the measured conductivity on each heat, not just a compliance claim.
