Start with the numbers. These free tools come from 30 years of building hardware supply chains in China. Each one gives you a decision-grade answer in about 60 seconds. No sign-up, no paywall, no supplier to sell you. 從數字開始。這兩件免費工具來自 30 年中國硬件供應鏈實戰，每一件 60 秒內給你一個可做決策的答案。免註冊、免費、不綁任何工廠、不收供應商佣金。
The freight line on the quote is not what you pay. The container count in the sales email is not what fits on the vessel. Run the numbers first.
報價單上的運費不是你要付的錢；銷售郵件裡的櫃數不一定裝得下。下單前，先把數字算出來。
What will shipping actually cost? Ocean freight with charge breakdown and transit time, before you pick an Incoterm.海運到底要多少錢？選貿易條件之前，先看清運費與附加費結構。
How many containers does this order really need? Check the fit by carton size and weight before you book the vessel.這張訂單到底要幾個櫃？訂艙前先按紙箱尺寸與重量算裝櫃。
The tools are free and always will be. The email list below is separate: it is the weekly memo, not a paywall.
工具永久免費。下面的 email 列表是另一件事：它是週報，不是付費牆。
The Weekly Cost Memo is one page: the moves in copper, plastics, steel and freight, what each means for your quotes, and one action each. Here is an example issue — illustrative numbers, real structure.
週報一頁看完：銅、塑膠、鋼、運費動向，對報價的影響，各配一個行動。下圖為一期示例——數字示意，結構真實。
| Commodity | Move | What moves it |
|---|---|---|
| Copper | ▲ +2.1% w/w | Grid demand, restocking ahead of Golden Week |
| ABS | → flat | Oil steady, feedstock quiet |
| Steel HRC | ▼ −1.4% w/w | Soft demand, mills cutting output |
| Ocean freight | ▲ +3% w/w | Carriers managing capacity before the holiday |
What it means: copper-heavy BOMs (motors, wiring) will feel quote pressure in 2-3 weeks — lock 60-day pricing now. ABS housings are stable: a good window to close annual pricing. Steel structural parts: ask suppliers for revised quotes.
Do this week: ① Re-quote your top 3 copper-sensitive suppliers. ② Book October sailings before Golden Week capacity cuts.
Illustrative example · composite figures for demonstration; the structure matches the real memo.
Every week: the 3 material or freight moves that matter for anything made in China (copper, plastics, steel, ocean freight), each with one line on what you should do about it. Written by someone who buys these materials for a living.
每週一封：銅、塑膠、鋼材與海運運價裡最值得知道的三個動向，各配一句「你該怎麼做」。由每天在買這些材料的人撰寫。
We never sell or share your address. Only the weekly memo, nothing else. Privacy: ask us anything.
