What decision should buyers make first?<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">Start with the reason for change: damage, a missing interface, a revised PCB, a new divider layout, or a changed handling route. A replacement request keeps the approved design. A retool request asks engineering to review whether the design itself must change.<\/p>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"part-2-which-evidence-defines-the-current-box\">Part 2. Which evidence defines the current box?<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">Record the model code, drawing revision, outer and usable dimensions, lid or divider arrangement, label area, stacking interface, item being handled, and route. Photographs help, but a photograph does not establish a tooling interface.<\/p>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"part-3-when-does-a-like-for-like-replacement-fit\">Part 3. When does a like-for-like replacement fit?<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">A direct replacement is the sensible path when the approved drawing, material requirement, and handling role remain unchanged. This route is suitable for a documented damaged unit or a quantity increase using the same accepted design.<\/p>\n<figure style=\"margin:26px 0;text-align:center\"><img decoding=\"async\" style=\"max-width:640px;width:100%;height:auto;display:block;margin:0 auto;border-radius:8px\" alt=\"Covered ESD container configuration for drawing review\" src=\"https:\/\/swesd.com\/wp-content\/uploads\/2026\/06\/Black-Anti-Static-Turnover-Bin-with-Lid-ESD-Bin-2.webp\" \/><\/figure>\n<p style=\"margin:0 0 16px;line-height:1.7\">The buyer should still confirm the current revision and receiving criteria. \u201cSame appearance\u201d is not enough when there are several box generations on one line.<\/p>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"part-4-which-changes-need-a-tooling-review\">Part 4. Which changes need a tooling review?<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">Request a retool assessment when a wall, footprint, internal feature, cover interface, divider location, label recess, or stacking feature changes. Any change that affects fit with a board, fixture, trolley, or automated interface should be documented on the revised drawing.<\/p>\n<blockquote>\n<p style=\"margin:0 0 16px;line-height:1.7\"><strong>Important:<\/strong> Do not turn a changed handling or protection requirement into a generic \u201csame ESD box\u201d order.

What risks should stop a quick substitution?<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">Pause the order when the existing drawing is missing, the defect is structural, the new item has different dimensions, or the route leaves the controlled area. A substitute can create fit, traceability, or packaging risk even when its outside dimensions look close.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">La <a href=\"https:\/\/swesd.com\/fr\/blog\/injection-molding-esd-box-oem-tooling-moq\/\">tooling and MOQ guide<\/a> is useful for a new-project tooling discussion.
