Things to watch (6)
From the version posted Oct 16, 2026.
- Serious: Quantity not stated. The text says Qty Change but gives no quantity or unit of issue, and a quote is priced per unit; check the solicitation before pricing.
- Worth checking: Set-aside unclear. SAM.gov shows no set-aside, but the clause list includes a Notice of Total Small Business Set-Aside; ask the contracting officer which applies.
- Worth checking: Special emphasis shipboard part. The O-ring is special emphasis material for a Seal Delivery Vehicle, with certification and material control rules (Material Control Division C) that add paperwork.

- Worth checking: Rubber material must meet toxicity and flammability rules. Use of any material other than the one specified needs special engineering approval and may require testing.
- Minor: Payment timing changed. Constructive acceptance under the prompt payment clause moves from 7 days to 45 days after delivery, which affects when you are paid.
- Minor: Mercury contamination means rejection. Mercury or mercury compounds must not be added to or touch the product.
