Payment structure: bid header 30-day CRAC payment vs ATC 95%/5% split

Bid Payment Timelines state payment within 30 days of CRAC (superseding GTC 10-day 100% payment), while ATC clause 10 withholds 5% basic until PBG is submitted.

• Bid p.2 Payment Timelines: pay seller within 30 days of CRAC and online bills (supersedes GeM GTC clause 12’s 10 days).
• GeM GTC clause 12 default: 100% within 10 days of CRAC unless STC/ATC specifies otherwise.
• ATC clause 10: 95% basic + 100% taxes within 30 days after receipt and acceptance; remaining 5% basic against PBG (warranty + 3 months claim).
• Practical reading: ATC is the more specific payment mechanism for this bid and should be priced/cashed-flowed as 95% + 5% retention against PBG, on the 30-day timeline rather than GTC’s 10 days.
• Separately, GTC Performance Security clause says payments become due only after receipt/verification of Performance Security — which interacts with the 5% retention and ePBG requirement.

Liquidated damages cap: ATC max 10% vs GeM GTC 5% (10% only for inordinate delay)

BDL ATC LD is 0.5%/week capped at 10% of delayed stores’ price; GeM GTC LD is 0.5%/week of delayed quantity value, generally capped at 5% of total contract value (10% only if delay is inordinate >25% of completion period).

• ATC clause 13: 0.5% of price of delayed stores (incl. duties, taxes) per week or part thereof, maximum 10%; tax increases during DP extension not borne by BDL if delay attributable to vendor.
• GTC clause 15(iii): 0.5% of contract value of delayed quantity per week, pre-estimated damages not exceeding 5% of total contract value; for inordinate delay maximum deduction 10%.
• Bidder should assume the buyer-specific ATC LD wording will be applied on this BDL contract, but note the GTC’s lower general cap if relying on GeM standard remedies — clarify with buyer if material.

PBG claim/validity buffer: ATC 3 months vs GeM GTC 2 months beyond obligations

ATC requires PBG valid till warranty + 3 months claim; GeM GTC states Performance Security valid for 2 months beyond completion of all contractual obligations including warranty. Bid ePBG duration is 21 months (fits 18-month warranty + 3 months).

• For this bid, ePBG Duration 21 months and ATC 18+3 months claim are aligned; treat 21 months / warranty+3 months as the required cover rather than GTC’s generic +2 months.

Single-tender foreign OEM product vs Class-1/Class-2-only MII eligibility

Bid is Single Tender limited to ELECTRONIC ENTERPRISES INDIA PRIVATE LIMITED for Krohn-Hite-7500, while MII clauses bar non-local suppliers and require min 50%/20% local content for Class 1/2.

• Technical scope is a named US-brand Krohn-Hite Model 7500 amplifier (Annexure-1).
• Simultaneously: Only Class-I and Class-II Local suppliers eligible; Non-Local suppliers not eligible; min 50% and 20% local content.
• This is a material eligibility/pricing tension for the sole listed seller (and any claimed MII status) — confirm how local-content classification is to be established for this OEM model.

Confirm sole eligible bidder and MII local-content treatment for Krohn-Hite 7500

Ask BDL to confirm whether only ELECTRONIC ENTERPRISES INDIA PVT LTD may bid, and how Class-1/Class-2 local-content thresholds apply to this foreign-OEM Model 7500 supply.

• Material to bid/no-bid and to any MII preference/eligibility declaration risk.
• If non-local content is inherent, seek written clarification on whether the MII participation filter is waived for this single tender/PAC-style buy.

Clarify operative payment milestones (100% at 30 days vs 95% + 5% on PBG)

Request confirmation that ATC clause 10 (95% basic + 100% taxes, 5% against PBG) overrides the bid-header ‘within 30 days of CRAC’ wording and GTC 10-day 100% default.

• Also confirm whether full ePBG 5% must still be submitted within 15 days of award before any payment becomes due (GTC 7(ii)), in addition to the 5% retention.

LD ceiling applicable on this contract

Ask whether BDL ATC max 10% LD or GeM GTC 5%/10%-inordinate-delay framework will be enforced.

• Affects delay risk pricing for a 6-month delivery of an imported instrument.

What exactly must be uploaded as ‘Certificate (Requested in ATC)’ and ‘Additional Doc 1’

Seek a definitive checklist mapping the GeM mandatory document fields to named ATC certificates to avoid technical rejection.

• GeM lists four seller document fields; ATC names OEM authorisation, compliance statement, service centres, etc., but does not label ‘Additional Doc 1’.

Acceptance demonstration logistics and delivery address

Request unmasked consignee address/contact and scope of ‘demonstration of item at BDL’ (on-site power, interfaces, pass criteria, who bears demo cost/time).

• Consignee address is redacted as ***********Visakhapatnam in the bid PDF; acceptance requires demonstration at BDL.

Accessories, options and exact configuration to price

Confirm whether only RK519, CAB-018 and CAB-025 are mandatory accessories, or any datasheet options (e.g. remote gain 011, extended warranty EW7500, other cables) are also required.

• Annexure datasheet lists multiple optional accessories; ATC names three specific accessories only.

Liquidated damages and strict delivery

Delivery within 06 months/180 days is of the essence; LD 0.5%/week up to 10% under ATC; tax increases during delay extension not borne by BDL if vendor-caused.

• Short Duration Bid published for emergency procurement of critical products/services — limited bid window (publish 12-09-2026, end 21-09-2026).
• GeM GTC also provides LD framework and treats >25% period delay as inordinate (up to 10%).

Performance security cash lock and payment retention

5% ePBG for 21 months plus ATC 5% basic retention against PBG; GTC makes payments due only after PBG receipt/verification — working-capital risk.

• GST may be held until invoice appears in GSTR-2B/2A.
• Failure to furnish performance security in time is a default ground under GeM GTC.

Warranty, free repair/replace and India service capability

18-month warranty with free repair/replace; seller expected to maintain India service group and upload nearby service-centre details — ongoing support liability for an imported instrument.

AS 9100D / counterfeit / access and quality liability

Stringent quality clauses: no non-conforming or counterfeit parts; notify process/provider changes; BDL/customer/regulator right of access across supply chain; retain records 3 years; ISO 14001:2015 EMS compliance.

• Counterfeit parts receipt triggers severe action against supplier.
• Supply not acknowledged as valid until all mandatory PO documents (inspection, warranty, ePBG, GST invoice, checklist) are provided.

Eligibility / single-tender and MII declaration risk

Single-tender restriction plus Class-1/2-only MII rule and land-border registration create high bid-rejection and false-declaration termination risk if classifications are wrong.

• False land-border declaration: immediate termination and further legal action.
• Undisclosed demerger can lead to debarment.
• Missing any sought certificate/document: offer liable to rejection.

No arbitration/mediation clause in bid header

Bid lists Arbitration Clause: No and Mediation Clause: No — dispute-resolution path is less favourable than multi-tier ADR and defaults to whatever GeM GTC/legal remedies remain.

Price and GST quoting risk

Bidders must self-check GST; reimbursement limited to actuals or applicable rates, whichever lower, and not above quoted GST % — under/over-quoting GST hurts margin or competitiveness.

• Statutory GST variation rules under GeM GTC allocate pre-bid-end GST changes to seller.

Inviting / buying organisation

Ministry of Defence — Department of Defence Production — Bharat Dynamics Limited (BDL).

• Office Name is masked as *********** in the bid PDF.
• Bid Number GEM/2026/B/8013829 dated 12-09-2026.
