Reflective Sheeting for North America: ASTM D4956 and MUTCD

What do North American buyers specify?

US and Canadian sign programs are built around ASTM D4956 performance Types. The MUTCD (Manual on Uniform Traffic Control Devices) frames how agencies maintain minimum retroreflectivity — it drives replacement cycles and therefore steady replacement demand for sheeting.

Which grades serve which program (demo map)

Program	Common starting point	Verify before RFQ
Regulatory / warning signs	HIP sheeting	Type III/IV family per SKU TDS
Higher-performance permanent signs	Microprismatic traffic	Type IV/VIII/IX/XI per report
Long approach / overhead guide signs	Long-distance films	Type VIII–XI candidates
Temporary traffic control	Work zone sheeting	Orange colorways, removable options

Practical import notes

• Roll goods: 1220 mm × 45.7 m master rolls, or 24/36/48 in × 50 yd — both conventions appear in US RFQs.
• Vehicle conspicuity (DOT C2) is a different product family (vehicle tape, e.g. ECE 104 / DOT C2 rated) — not covered by this traffic-sign catalog.
• State DOT approved-products lists (APLs) may apply for agency work; private/commercial signage is less restricted.

Agency or project spec reference, ASTM Type, colors, roll or panel size, print process, quantity, destination port, and whether certification documents must name a specific lab.
