They look alike on a peg hook and differ in cost, security and how angry your customer gets opening one. https://jchtrade.com/notes/corrugated-pop-displays-floor-counter-hook/ https://jchtrade.com/notes/corrugated-pop-displays-floor-counter-hook/ Wed, 30 Sep 2026 09:00:00 +0000 Most retail displays that sit on a store floor for a season are printed corrugated board. What the formats are, why the board and the print decide the cost, what published prices look like, and what to send for a quote. https://jchtrade.com/notes/two-shot-molding-vs-overmolding/ https://jchtrade.com/notes/two-shot-molding-vs-overmolding/ Wed, 30 Sep 2026 09:00:00 +0000 Both put a soft layer on a rigid part. One uses two ordinary tools, the other one complex tool and a two-barrel press. Volume decides most of it; the bond decides whether the part survives. https://jchtrade.com/notes/what-is-powder-coating/ https://jchtrade.com/notes/what-is-powder-coating/ Wed, 30 Sep 2026 09:00:00 +0000 Powder coating is paint applied as a dry, electrostatically charged powder and baked into a hard film. How the line runs, which powder suits which use, and the two tests that turn "powder coat, black" into a finish you can inspect. https://jchtrade.com/notes/tariff-math-moving-one-product-from-china-to-taiwan/ https://jchtrade.com/notes/tariff-math-moving-one-product-from-china-to-taiwan/ Tue, 29 Sep 2026 09:00:00 +0000 A single molded part, landed in the US from China and from Taiwan, line by line: the duty stack, the Merchandise Processing Fee, the harbor fee, freight and the one-time cost of moving the tool. Then the number that decides it: how much more Taiwan can charge before the move stops paying. https://jchtrade.com/notes/minimum-order-quantity-what-is-negotiable/ https://jchtrade.com/notes/minimum-order-quantity-what-is-negotiable/ Mon, 28 Sep 2026 09:00:00 +0000 A factory's minimum is its setup, material and machine-time costs written as a quantity. Know which cost drives the number and you'll know what you can negotiate, what you can't, and when the minimum is really a no. https://jchtrade.com/notes/what-an-injection-mold-really-costs/ https://jchtrade.com/notes/what-an-injection-mold-really-costs/ Thu, 24 Sep 2026 09:00:00 +0000 Published 2026 ranges for prototype aluminum, P20 and hardened H13 tools, single, multi-cavity and family molds, hot runner against cold, US against China — and why we will not print a Taiwan number we cannot back. https://jchtrade.com/notes/taiwan-vs-china-tariffs-for-us-importers/ https://jchtrade.com/notes/taiwan-vs-china-tariffs-for-us-importers/ Tue, 22 Sep 2026 09:00:00 +0000 China-origin goods still carry the 2018 Section 301 lists, and since July 24, 2026 a 12.5% duty on top. Taiwan-origin goods are generally topped up to 10% combined. The 2026 rate stack, layer by layer, with the official sources. https://jchtrade.com/notes/taiwan-is-a-small-island-the-shops-are-not-interchangeable/ https://jchtrade.com/notes/taiwan-is-a-small-island-the-shops-are-not-interchangeable/ Sun, 13 Sep 2026 09:00:00 +0000 Taiwan's tool and machine-tool trades sit in a few dozen kilometers.

Origin is still the floor — a China lot stuffed at Keelung is still China. https://jchtrade.com/notes/the-golden-sample-was-perfect-lot-three-was-not/ https://jchtrade.com/notes/the-golden-sample-was-perfect-lot-three-was-not/ Sun, 13 Sep 2026 09:00:00 +0000 A signed sample proves one unit was made well. It does not prove the line will hold that unit at volume. Here is the swap — resin, steel, a different line, a quiet subcontract — and the only cheap place to catch it. https://jchtrade.com/notes/reverse-engineering-from-a-sample-what-the-part-cannot-tell-you/ https://jchtrade.com/notes/reverse-engineering-from-a-sample-what-the-part-cannot-tell-you/ Tue, 08 Sep 2026 09:00:00 +0000 A scanned sample gives you geometry, not a specification. Here's what a scan-to-CAD job actually produces, where tolerance decisions get made, how first-article inspection can quietly lie to you, and when reverse engineering is the wrong move. https://jchtrade.com/notes/payment-terms-asia-manufacturing-deposits-escrow-letters-of-credit/ https://jchtrade.com/notes/payment-terms-asia-manufacturing-deposits-escrow-letters-of-credit/ Sat, 05 Sep 2026 09:00:00 +0000 Why the standard 30/70 wire means you pay in full before you see a single part, what goes wrong when you do, and how to restructure the balance so some money still sits behind something you can verify. https://jchtrade.com/notes/real-factory-or-trading-company-verify-before-deposit/ https://jchtrade.com/notes/real-factory-or-trading-company-verify-before-deposit/ Sat, 05 Sep 2026 09:00:00 +0000 The business license settles most of it in ten minutes, and almost nobody reads the right field.
