The Electronic Manufacturing Services Data Guide (2026)

The 8 primary records sort into four working groups: production surveys, customs-grade trade APIs, association and marketplace intelligence, and end-of-life environmental tracking. Seven related records from adjacent industries extend the pool to 15.

Production survey: the demand-cycle backbone

• Census M3 – Manufacturers' Shipments, Inventories & Orders (quality score 9): the only source here publishing monthly value of shipments, new orders, unfilled orders and inventories tabulated across about 89 industry categories predominantly at 6-digit NAICS, aggregated to groups such as 34S Computer and Electronic Products. Series run January 1992 to present in both seasonally adjusted and not-seasonally-adjusted form; SIC-basis series reach back to 1958 and the survey itself dates to 1957. The bulk CSV holds roughly 600,000 rows (420 months x 174+ series x adjustment flags) plus six NAICS Excel workbooks of ~550 KB each, all commercial delivery terms with attribution requested. Current-month estimates are preliminary and historical series are rebenchmarked annually.

Trade APIs: HS-coded flows on both sides of the ledger

Association and marketplace intelligence

• Global Electronics Association (IPC) – Statistical Programs & EMS Intelligence (score 8): the sole industry-association record in the pool. Monthly North American EMS shipments and book-to-bill releases publish by the end of the following month; participant-only splits cover production type, company size tier and vertical market, and program membership means contributing your own company data during an annual enrollment window.
• GlobalSources EMS Supplier Directory – 72k Products from 856 Vendors (score 7): 72,633 EMS and PCBA service listings from 857 suppliers — roughly 908 pages at 80 listings each — exposing FOB price ranges, minimum order quantities, factory country and capability descriptions without login. Coverage centers on Shenzhen, Dongguan, Xiamen and Jinjiang, refreshed continuously by vendors with no historical archive.

End-of-life and discovery layers

Ten recurring jobs define how teams put this pool to work, and each maps to named records:

Datadory delivers this dataset fully structured and normalized, ready for direct analysis without manual pipeline configuration or schema parsing.

Market researchers and consultants. Searches like "EMS book-to-bill ratio history" map onto IPC's monthly releases, published by the end of the following month, while market-sizing questions resolve to the related Census Economic Census, ASM and County Business Patterns family for establishment, payroll and product-shipping series. Consultants pinning down the correct series code for computer and electronic products output land on NAICS 334 in M3. The market researchers hub ranks these sources against alternatives.

Sourcing managers and procurement teams. Queries like "PCBA supplier directory Shenzhen" and "FOB price MOQ electronics sourcing" point at GlobalSources' 72,633 listings across 857 suppliers — FOB price bands, minimum order quantities and factory country readable without login, concentrated in Shenzhen, Dongguan, Xiamen and Jinjiang.

Trade analysts, logistics analysts and ESG researchers. Customs-district breakouts ("electronics imports by customs district") come from the imports-by-HS API with calculated duty attached; port-level routing questions ("US electronics trade data by port") resolve through USA Trade Online Reimagined's port detail from 2003; and sustainability teams searching "California e-waste recycling statistics" get CalRecycle's covered e-waste series from 2005 alongside per-capita disposal trends by jurisdiction.

A working stack starts with the production cycle and layers trade, sourcing and end-of-life evidence on top. Six steps cover most teams:

Fifteen of the 1,744 datasets Datadory catalogs serve electronic manufacturing services — 8 primary and 7 related. Quality skews high: the mean score across the 8 primaries is 7.9 out of 10, led by three records at 9, and 5 of the 8 refresh monthly. The table below collects the numbers worth quoting.

Eight questions cover most of what searchers ask about this pool — booking cycles, tariff detail, supplier pricing, port-level trade and machine-learning rights.
